PART I

Item 1. Business

Overview

Ritter Pharmaceuticals, Inc. develops novel therapeutic products that modulate the human gut microbiome to treat gastrointestinal diseases. We are advancing human gut health research by exploring the metabolic capacity of the gut microbiota and translating the functionality of prebiotic-based therapeutics into applications intended to have a meaningful impact on a patient’s health.

Our first novel microbiome modulator, RP-G28, an orally administered, high purity galactooligosaccharide (“GOS”), is currently under development for the reduction of symptoms associated with lactose intolerance. RP-G28 is designed to stimulate the growth of lactose-metabolizing bacteria in the colon, thereby effectively adapting the gut microbiome to assist in digesting the lactose that reaches the large intestine. RP-G28 has the potential to become the first drug approved by the Food and Drug Administration (“FDA”) for the reduction of symptoms associated with lactose intolerance. RP-G28 has been studied in a Phase 2a clinical trial and an adaptive design Phase 2b/3 clinical trial and is a first-in-class compound.

On October 17, 2016, we announced that the last patient had completed dosing and all monitoring visits in our Phase 2b/3 clinical trial of RP-G28 for the treatment of lactose intolerance. Topline results of the trial are expected to be announced in the first quarter of 2017. The Phase 2b/3 trial is a double-blind, placebo-controlled, three arm, multicenter study evaluating safety, efficacy and tolerability of two dosing regimens of RP-G28 in patients with moderate to severe lactose intolerance symptoms. Enrollment was initiated in March 2016 and completed in August 2016, achieving our projected enrollment time period. The study aims to evaluate a patient’s ability to consume dairy foods post-treatment with improved tolerance and reduced digestive symptoms. A total of 377 subjects were enrolled in the trial with 18 clinical sites participating throughout the United States. Patients underwent a 30-day treatment, followed by a 30-day post-treatment evaluation of dairy tolerance. A subset of subjects have been rolled into a 12-month extension study to evaluate long-term durability of treatment. The study will also evaluate each participant’s microbiome, expanding knowledge of the effects that RP-G28 may have on adapting the gut microbiota in a beneficial manner. The subjects are expected to complete the 12-month evaluation during the fourth quarter 2017.

We have had communications with the FDA regarding our clinical program and regulatory path towards getting RP-G28 adequately studied and eventually approved. We intend to hold two meetings with the FDA in the near future about our Phase 2b/3 study, including a Type C meeting as well as an End of Phase 2 meeting, both of which the FDA has encouraged us to schedule. These meetings and communications are typical for development stage companies and include the clinical pathway, regulatory requirements, statistical plan and endpoints and similar matters.

The Gut Microbiome

The human gut is a relatively under-explored ecosystem but provides a great opportunity for using dietary intervention strategies to reduce the impact of gastrointestinal disease. The human body carries about 100 trillion microorganisms in the intestines, which is 10 times greater than the number of cells in the human body. This microbial population is responsible for a number of beneficial activities such as fermentation, strengthening the immune system, preventing growth of pathogenic bacteria, providing nutrients, and providing hormones. The increasing knowledge of how these microbial populations impact human health provides opportunities for novel therapies to treat an assortment of diseases such as neurological disease, cardiovascular disease, obesity, irritable bowel syndrome, inflammatory bowel disease, colon cancer, allergies, autism and depression.

Platform Approach

Our platform is based on selectively colonizing microbiota (increasing beneficial bacteria) in the colon, and thus changing the colon’s composition of microbiota. This process has been shown to stimulate the growth of endogenous bifidobacteria, which after a short feeding period become predominant in the colon. The result is believed to reduce inflammation and improve digestion, thereby potentially reducing digestive symptoms.

RP-G28 selectively increases colonization of lactose-metabolizing bacteria in the colon, such as bifidobacteria and lactobacilli, without increasing the growth of harmful bacteria, such as Escherichia coli (“E. coli”). Increased colonization of lactose-metabolizing colonic microbiota is associated with increased lactase activity, thereby increasing the fermentation of lactose into galactose, glucose and short chain fatty acids. We believe this process could reduce lactose-derived gas production and thereby mitigate the symptoms of lactose intolerance.

Lactose Intolerance

Studies have suggested that lactose intolerance is a widespread condition affecting over one billion people worldwide and over 40 million people in the United States (or 15% of the U.S. population), with an estimated nine million of those individuals demonstrating moderate to severe symptoms.

Current annual spending on over-the-counter lactose intolerance aids in the United States has been estimated at approximately $2.45 billion. However, these options are limited and there is no long-term treatment available.

Lactose intolerance develops in lactose maldigesters when consuming too much lactose or when lactose is added to a previously low-lactose diet. People with lactose maldigestion have a low activity level of lactase, the enzyme responsible for breaking down human lactose, located in the brush border membrane of the small intestine. Lactose intolerance is characterized by one or more of the cardinal symptoms; including abdominal pain/cramps, bloating, gas, and diarrhea following the ingestion of lactose or lactose-containing foods.

In lactose maldigesters, unhydrolyzed lactose passes into the large intestine, where it is fermented by the indigenous microflora into gases and short chain fatty acids. The excessive gas production and the osmotic effects of excessive undigested lactose cause the symptoms of lactose intolerance. Symptoms begin about 30 minutes to two hours after eating or drinking foods containing lactose. The severity of symptoms depends on many factors, including the amount of lactose a person can tolerate and a person’s age, ethnicity, and digestion rate. The symptoms of lactose intolerance are caused by gases and toxins produced by anaerobic bacteria in the large intestine. The problem of lactose intolerance has been exacerbated because many foods and drinks contain traces of lactose without lactose being clearly stated on the product’s label.

Diagnosis

Lactose intolerance is often diagnosed by evaluating an individual’s clinical history, which reveals a relationship between lactose ingestion and onset of symptoms. Hydrogen breath tests may also be utilized to diagnose lactose malabsorption and a milk challenge may be used to differentiate between lactose malabsorption and lactose intolerance. Further tests can be conducted to rule out other digestive diseases or conditions, including: stool examination to document the presence of a parasite, blood tests to determine the presence of celiac disease, and intestinal biopsies to determine mucosal problems leading to malabsorption, such as inflammatory bowel disease or ulcerative colitis.

Our History

We were formed as a Nevada limited liability company on March 29, 2004 under the name Ritter Natural Sciences, LLC. Our first prototype, Lactagen^™, was an alternative lactose intolerance treatment method. In 2004, clinical testing was conducted, which included a 60 subject double-blind placebo controlled clinical trial. The results were published in the Federation of American Societies for Experimental Biology in May 2005 and demonstrated Lactagen^™ to be an effective and safe product for reducing symptoms for nearly 80% of the clinical participants who were on Lactagen^™.

In 2008, we expanded our focus by developing a prescription drug development program. We initiated the program by developing RP-G28, a second generation edition of Lactagen^™. We believe that RP-G28 enables us to state stronger claims, garner more medical community support and reach a wider market in the effort to treat lactose intolerance.

To help fund the development of RP-G28, we were awarded a grant from the United States government’s Health Care Bill program, the Qualifying Therapeutic Discovery Project, in 2008. The grant program provides support for innovative projects that are determined by the U.S. Department of Health and Human Services to have reasonable potential to result in new therapies that treat areas of unmet medical need and/or prevent, detect or treat chronic or acute diseases and conditions.

On September 16, 2008, we converted into a Delaware corporation under the name Ritter Pharmaceuticals, Inc.

Our Leading Product Candidate — RP-G28

Overview

RP-G28 is a novel highly purified GOS, which is synthesized enzymatically. The product is being developed to reduce the symptoms and frequency of episodes of abdominal pain associated with lactose intolerance. The therapeutic is taken orally (a powder solution mixed in water) for 30 consecutive days. The proposed mechanism of action of RP-G28 is to increase the intestinal growth and colonization of bacteria that can metabolize lactose to compensate for a patient’s intrinsic inability to digest lactose. Once colonization of bacteria has occurred, it is hypothesized that patients will continue to tolerate lactose as long as they maintain their microflora balance. RP-G28 has the potential to become the first FDA-approved drug for the reduction of symptoms associated with lactose intolerance.

Galactooligosaccharides (GOS)

RP-G28 is a >95% purified GOS product. GOS refers to a group of compounds containing β-linkages of 1 to 6 galactose units with a single glucose on the terminal end and are found at low levels in human milk. GOS products resist hydrolysis by salivary and intestinal enzymes because of the configuration of their glycosidic bonds and reach the colon virtually intact. The undigested GOS enhances the growth of beneficial, lactose metabolizing, colonic bacteria that already exist in the subject’s digestive track, including multiple species and strains of bifidobacteria and lactobacilli. Once colonies of these bacteria have increased, continued lactose exposure should maintain tolerability of lactose without further exposure to RP-G28.

The significance of a higher purity GOS, namely RP-G28, was highlighted in a 2010 study by Klaenhammer. The in vitro study concluded that RP-G28 promoted growth of lactobacilli and bifidobacteria, but did not promote multiple strains of E. coli. In contrast, lower purity GOS stimulated both bifidobacteria as well as the strains of E. coli evaluated. (As seen below in Figure 1, NCK 430 (e. coli) grew in the presence of low purity GOS (GOS 2). Alternatively, the higher purity GOS (RP-G28/GOS 1) did not promote the growth of E. coli.).

Figure 1

Mechanism of Action

RP-G28 selectively increases colonization of lactose-metabolizing bacteria in the colon, such as bifidobacteria and lactobacilli, without increasing the growth of harmful bacteria, such as E. coli. Increased colonization of lactose-metabolizing colonic bacteria is associated with increased lactase activity and GOS utilization, thereby increasing the fermentation of lactose into galactose, glucose and short chain fatty acids. Digestion of lactose reduces lactose-derived gas production and thereby mitigates the symptoms of lactose intolerance.

Safety & Toxicology of GOS

Clinical studies of GOS products were reviewed as part of the safety evaluation to support our Investigational New Drug (“IND”) Application for RP-G28. The safety of GOS products in humans has been evaluated in 486 adults at doses of 2.5 to 15 gm/day for up to 14 weeks, 342 children at doses of 2.0 – 2.4 gm/day for up to 1 year, and in 2415 newborns and infants for up to 6 months. Overall, no reports of severe adverse events attributable to the consumption of GOS were reported in the literature.

Among the studies that included tolerance endpoints, side effects were limited to reports of flatulence, fullness, gastronintestinal symptoms, and changes in stool consistency and frequency when GOS was consumed on a repeat basis at quantities of between 5.5 to 15 g/day (Ito 1990; Deguchi 1997; Teuri 1998); however, this effect was not consistently reported in all studies (Teuri and Korpela 1998; Depeint 2008; Drakoularako 2010; van de Heuval 1998; van Dokkum 1999; Bouhnik 2004; Sairanen and Piirainen 2007; Shadid 2007). Similar observations of increased flatulence have been reported following the consumption of fructooligosaccharides (15 gm/day) over a 7-day period (Alles 1996), and this symptom represents a localized effect that is expected in association with the consumption of indigestible fiber in large quantities. There were no reports of events in other System Organ Class (“SOC”) suggestive of systemic toxicity.

RP-G28 Clinical Safety

In addition to the nonclinical studies evaluating GOS products, the safety of RP-G28 for clinical investigation is supported by clinical safety results from our Phase 2a study, G28-001. In this study, RP-G28 was escalated from 1.5 grams per day to 15 grams per day over a 35-day dosing period.

RP-G28 was well-tolerated. There were no serious adverse effects. The most common adverse effects were headache, dizziness, nausea, upper respiratory tract infection, nasal congestion and pain. All adverse effects were mild or moderate in severity, and event occurrence was distributed over the treatment and post-treatment follow-up phase. No clinically significant changes or findings were noted from clinical lab evaluations, vital sign measurements, physical exams, or 12-lead electrocardiograms.

Our Market Opportunity

Unmet Medical Needs

Lactose intolerance is a challenging condition to manage. According to a market research study conducted by Objective Insights in April 2012, approximately 60% of lactose intolerant sufferers reported experiencing symptoms daily, or bi-weekly. Not only can symptoms be painful and embarrassing, they can also dramatically affect one’s quality of life, social activities, and health. Currently there are few reliable, or effective, treatments available that provide consistent or satisfactory relief.

Currently, there is no approved prescription treatment for lactose intolerance. Most persons with lactose intolerance avoid ingestion of milk and dairy products while others substitute non-lactose-containing foods in their diet. However, complete avoidance of lactose-containing foods is difficult to achieve (especially for those with moderate to severe symptoms) and can lead to significant long-term morbidity (i.e., dietary deficiencies of calcium and vitamin D).

At the 2010 National Institute of Health (“NIH”) Consensus Development Conference: Lactose Intolerance and Health, the NIH highlighted numerous health risks tied to lactose intolerance such as: osteoporosis; hypertension; and low bone density. There is substantial evidence indicating that lactose intolerance is a major factor in limiting calcium and nutrient intake in the diet of people who are lactose intolerant. Adequate calcium intake is essential to reducing the risks of osteoporosis and hypertension. In addition, chronic calcium depletion has been linked to increased arterial blood pressure in over 30 published reports, thereby establishing a relationship between hypertension and low calcium intake. Moreover, there is evidence of a correlation between calcium intake and both colon and breast cancer.

Treatment Options

Doctors generally recommend the following treatments for the management of lactose intolerance: (1) dairy avoidance; (2) lactase supplements; (3) probiotics/dietary supplements; and (4) dairy substitutes/lactose free products. Despite educating their patients on all viable treatment options, physicians tend to advise their patients to refrain from consuming any dairy products whatsoever. However, in a 2008 survey conducted by Engage Health, 47% of lactose intolerance sufferers reported that this method was not effective (largely due to hidden dairy products in ingredients), and only 30% of lactose intolerance sufferers reported lactase supplements as being effective in managing their lactose intolerance. Further, while probiotics/dietary supplements have been demonstrated to aid and support one’s digestive system, helping break down general foods consumed, they don’t directly help with lactose intolerance. The 2008 survey by Engage Health suggests that the majority of lactose intolerance patients are dissatisfied with current treatment options.

Patients Unsatisfied with Current Management Options

Growing Awareness

Lactose intolerance is a condition that continues to expand as society advances and evolves. It has been estimated that gastroenterologists see approximately 15 new patients with lactose intolerance each month. Education and awareness have increased, and the American diet has greatly changed over the past decade to include more dairy-based goods. As the populace is growing older, the prevalence of lactose intolerance is increasing because more people tend to develop lactose intolerance later in life. Increased education and diagnosis is making more people aware of their allergies and digestive conditions. Physicians may compound the growth of lactose intolerance prevalence and its associated disorders by recommending individuals to avoid dairy products, a practice which in and of itself may increase severity of the intolerance.

Doctors tend to diagnose lactose intolerance in a patient before the patient is able to self-diagnose it. However, patients tend to initiate discussion about lactose intolerance with their doctors. This is indicative of broad public awareness of lactose intolerance. Doctors often administer two tests for diagnosing lactose intolerance: (i) a symptom history test and (ii) a hydrogen breath test.

Our Competitive Strengths

Market Opportunity

RP-G28 has the potential to become the first approved drug in the United States and Europe for the reduction of symptoms associated with lactose intolerance.

See “Business—Intellectual Property” for additional information regarding our patent portfolio.

Our Growth Strategy

In order to achieve our objective of developing safe and effective applications to treat conditions associated with microbiome dysfunctions, our near-term and long-term strategies include the following:

Clinical and Regulatory

IND Application/Phase 1

We submitted an IND application for RP-G28 to the FDA in June 2010. Because the safety and tolerability profile, pharmacokinetics and dose response curve of GOS products is generally well understood, as part of our IND submission, we proposed that the data supporting the IND was sufficient to support a Phase 2 proof-of-concept study in a small number of lactose-intolerant patients. The FDA agreed with this proposal and the typical Phase 1 clinical program in healthy volunteers was replaced with a Phase 2a program in subjects with lactose intolerance.

On June 28, 2010, we received an advice letter from the FDA regarding our IND submission. The FDA suggested that we (1) consider expanding our inclusion criteria to include females of childbearing potential who are willing to use appropriate contraception throughout the duration of the protocol; (2) follow the FDA’s guidance regarding Patient-Reported Outcome Measures; and (3) include a pharmacokinetic study in our proposed Phase 2a trial to determine the extent of systemic exposure of RP-G28.

Phase 2a Study

In June 2011, we began a Phase 2a clinical trial on RP-G28 to validate the efficacy, safety, and tolerance of RP-G28 compared to placebo when administered to subjects with symptoms of lactose intolerance. The clinical results from the study, which concluded at the end of 2011, showed that RP-G28 improved lactose digestion versus placebo as measured by the improvement in digestive symptoms associated with lactose intolerance and decline in hydrogen production present in a hydrogen breath test.

On June 12, 2013, we announced positive data from our Phase 2a first-in-human, proof of concept clinical study of RP-G28. The purpose of the study was to assess the effectiveness, safety and tolerability of RP-G28 compared to a placebo when administered to subjects with symptoms associated with lactose intolerance. The results were presented at Digestive Diseases Week and the New York Academy of Sciences Conference on Probiotics, Prebiotics and the Host Microbiome: The Science of Translation, and co-sponsored by the Sackler Institute for Nutrition Science and the International Scientific Association of Probiotics and Prebiotics.

The clinical microbiome data from this Phase 2a clinical trial of RP-G28 in patients with lactose intolerance was published in the Proceedings of the National Academy of Science (“PNAS-Plus”) PNAS 2017; Early Edition, published ahead of print January 3, 2017. The paper titled, “Impact of short-chain galactooligosaccharides on the gut microbiome of lactose-intolerant individuals,” reports findings on our lead therapeutic candidate, RP-G28, a short-chain GOS. The data validates RP-G28’s mechanism of action and supports the product as a potential treatment for lactose intolerance. The newly published microbiome data provides further insight into RP-G28’s Phase 2a 2013 clinical trial.

The double-blinded, randomized, multi-center, placebo-controlled Phase 2a study evaluated RP-G28 in 62 patients with lactose intolerance over a treatment period of 35 consecutive days. Post-treatment, subjects reintroduced dairy into their diets and were followed for an additional 30 days to evaluate lactose digestion, as measured by hydrogen production and symptom improvements. In order to confirm lactose intolerance and study participation, subjects underwent a 25-gram lactose challenge in the clinic. Lactose intolerance symptoms and hydrogen production via hydrogen breath test were assessed for six hours post-lactose dose. Eligible subjects were required to demonstrate a minimum symptom score and a “positive” hydrogen breath test in order to be eligible for randomization. A “positive” breath test was defined as a hydrogen gas elevation of 20 parts per million (ppm) at two time-points within the six hours following a lactose-loading dose. The primary endpoints included tracking patients’ gastrointestinal symptoms via a patient-reported symptom assessment instrument (a Likert Scale, measuring individual symptoms of flatulence, bloating, cramping, abdominal pain and diarrhea, on a scale of 0 (none) to 10 (worst)) at baseline, day 36 and day 66; as well as the measurement of hydrogen gas levels in their breath following a 25-gram lactose challenge.

RP-G28 was well tolerated, with no significant adverse events reported. The Phase 2a study demonstrated clinically meaningful benefits to patients on treatment, whereas treated subjects reported increased tolerance to lactose and dairy foods: reduced lactose intolerance symptoms (gas, bloating, cramping and abdominal pain) were reported in subjects on RP-G28, a durable reduction in abdominal pain (p=0.019) was reported, and treated patients were six times more likely to describe themselves as lactose tolerant (p=0.039). In sum, positive trends were seen when the entire per protocol study population was analyzed, including some statistically significant subgroup analysis, suggesting that a therapeutically positive effect is seen. Although there were few primary and secondary efficacy endpoints with statistically significant results, the combined data suggest that RP-G28 is exerting a positive therapeutic effect. We believe these positive drug effect trends combined with the benign safety profile support continued drug development of RP-G28.

Key findings of the Phase 2a study include:

Figure 2

In the Phase 2a study, changes in the fecal microbiome were investigated using both Terminal Restriction Fragment Length Polymorphisms (“TRFLP”), a molecular biology technique for profiling microbial communities based on the position of a restriction site closest to a labeled end of an amplified gene, and microme analysis of 16S rRNA genex by pyrosequencing, a method of DNA sequencing (determining the order of nucleotides in DNA).

Figure 3

In addition, Principal Component Analysis (“PCA”), a multivariate method that helps transform a number of possibly correlated variables into a smaller number of uncorrelated variables called principal components, thereby reducing the dimensions of a complex dataset, showed statistically significant shifts in the microbiome of subjects fed RP-G28, compared to placebo, at 66 days. Specifically, RP-G28 significantly altered the microbiomes of 82% of the study participants who received the treatment. See Figure 3 above.

Pre-treatment, three distinct clusters were identified, whereas post-treatment (Day 66) two distinct clusters were identified, showing a clear shift in certain species represented before and after treatment.

Principal Coordinates Analysis (“PCoA”), a multivariate method that helps visualize similarities and dissimilarities in large datasets, was also utilized to analyze the microbiome data. For analysis of 16S amplicon sequencing data, we created Unweighted Unifrac similarity matrices (that is we conducted PCoA) and applied ANOSIM (Analysis of Similarities) and PERMANOVA (Permutational Analysis of Variance) statistical analyses. Our analysis showed a significant association between Day (day 0 or baseline, and day 36 and 66 as categories) and microbiome composition (ANOSIM R = 0.218, P = 0.0001, PERMANOVA Pseudo-F = 3.4318, P = 0.0001). These data indicate that RP-G28 and subsequent introduction of lactose into the diet had impacted the fecal microbiome of participants. Further, lactose metabolizing bacteria were shown to increase in the treatment group.

The results of our Phase 2a study were published in Nutrition Journal in a manuscript entitled “Improving lactose digestion and symptoms of lactose intolerance with a novel galactooligosaccharide (RP-G28): a randomized, double-blind clinical trial.”

We held a Type C meeting with the FDA’s Division of Gastroenterology and Inborn Errors Products on February 20, 2013. The purpose of the meeting was to obtain the FDA’s feedback on the planned Phase 2 program and Phase 3 programs, inform the FDA of our ongoing development plans, gain feedback on relevant clinical trial design and end points related to patient meaningful benefits, and to inform the FDA of the status of our product characterization. We believe that this meeting was a significant step forward in streamlining the pathway to initial U.S. approval of RP-G28 to reduce symptoms and frequency of symptomatic episodes associated with lactose intolerance. The meeting and official meeting minutes provided valuable guidance on the development path of RP-G28:

Following analysis of the Phase 2a clinical trial, discussions with the FDA in 2013 about our clinical development plan, and further discussions with our regulatory consultants, we initiated a Phase 2b/3 clinical trial of RP-G28 in March 2016. We believe this trial could serve as one of two pivotal trials should the resulting data and the FDA be supportive of this trial as a pivotal trial. We did not discuss the Phase 2b/3 study design and development plan with the FDA before initiating the study in March 2016, though we did submit a supplement to the IND detailing the protocols for the adaptive study and intend to hold two meetings with the FDA in the near future.

Nonclinical Safety Plans

Given the established safety profile of GOS in humans and the lack of significant safety concerns with RP-G28 administered to subjects in the Phase 2a study, no additional non-clinical safety studies are planned to support continued evaluation of RP-G28 in the Phase 2 program.

Guidelines adopted by the FDA and established by ICH require nonclinical studies that specifically address female fertility to be completed before the inclusion of women of child bearing potential in large-scale or long-duration clinical trials (e.g., Phase 3 trials). In the United States, such assessments of embryo-fetal development can be deferred until before Phase 3 using precautions to prevent pregnancy in clinical trials. As the FDA recommended in their June 28, 2010 advice letter, we will continue to evaluate females of child-bearing potential who are willing to use appropriate contraception throughout the duration of any study.

Phase 2b/3 Study

Enrollment in our Phase 2b/3 clinical trial of RP-G28 was initiated in March 2016 and completed in August 2016. The final patient completed dosing and all monitoring visits in October 2016. Topline results of this trial are expected to be announced in the first quarter of 2017.

The Phase 2b/3 study was designed as a multi-center double-blinded, placebo controlled clinical trial of approximately 377 subjects to determine the maximum tolerated dose and optimal dose-escalation schedule for RP-G28. The trial assessed patients with moderate to severe abdominal pain as measured by a pain Likert scale after a lactose challenge. The Phase 2b/3 clinical trial was intended to measure additional lactose intolerance symptoms (gas, bloating, diarrhea, cramps) as secondary endpoints. Entry criteria in the Phase 2b/3 study included a hydrogen breath test to validate lactase deficiency. The Phase 2b/3 study design included a screening phase; a 30-day course treatment phase and a 30-day post-treatment evaluation phase. The study was designed to gradually escalate the dose beyond the 15 gm/day dose level evaluated in the Phase 2a study. Study subjects abstained from lactose containing food products and were then randomized evenly (1:1:1:1) to receive one of three doses of RP-G28 or placebo for 30 days. Subjects were then followed post-treatment for an additional 30 days while lactose containing food products were re-introduced into their diets. The primary endpoint for the Phase 2b/3 clinical study was a durable reduction in abdominal pain, with secondary endpoints measuring changes in individual lactose intolerance symptoms (gas, bloating, diarrhea, cramps). The Phase 2b/3 study was also designed to include collection of blood samples to assess systemic exposure to RP-G28 using measurement of serum concentrations of a trisaccharide. This was monitored as a surrogate to assess the systemic bioavailability of orally administered RP-G28. Additionally, the study required the collection of fecal samples from patients enrolled to evaluate the baseline and changes to the patient’s microbiome that correlate to symptom reduction and lactose tolerance.

In order to gather long-term data on subjects exposed to RP-G28, we also offered enrollment in an observational extension study, G28-004, to subjects who completed the Phase 2b/3 protocol. As RP-G28 is expected to provide extended relief from lactose intolerance symptoms beyond the initial 30-day treatment phase, this extension study for the Phase 2b/3 program will assess the long-term treatment effect. We intend for the results from this study to guide the need to evaluate an additional 30-day course of treatment in a Phase 3 clinical trial in subjects who experience the return of lactose intolerance symptoms after an initial course of RP-G28.

Adaptive seamless phase 2b/3 designs, such as the Phase 2b/3 pivotal clinical trial for RP-G28, are aimed at interweaving the two phases of full development by combining them into one single, uninterrupted study conducted in two steps. Adaptive seamless phase 2b/3 designs enable a clinical trial to be conducted in steps with the sample size calculation selected on the basis of data observed in the first step to continue along to the second step. The main statistical challenge in such a design is ensuring control of the type I error rate. Most methodology for such trials is based on the same endpoint being used for interim and final analyses. A type I error is one in which the adaptation process leads to design, analysis, or conduct flaws that introduce bias that increases the chance of a false conclusion that a treatment is effective (a type I error). Controlling type I error can be accomplished by prospectively specifying and including in the statistical analysis plan all possible adaptation plans that may be considered during the course of the trial. We worked with Covance, Inc. (“Covance”), a contract research organization (“CRO”) to control a type I error in our Phase 2b/3 study.

We did not discuss the Phase 2b/3 study design and development plan with the FDA before initiating the study in March 2016, though we did submit a supplement to the IND detailing the protocols for the adaptive study and have subsequently had communications with the FDA regarding our clinical program. We intend to hold two meetings with the FDA in the near future about our Phase 2b/3 study, including a Type C meeting as well as an End of Phase 2 meeting, both of which the FDA has encouraged us to schedule. These meetings and communications are typical for development stage companies and include the clinical pathway, regulatory requirements, statistical plan and endpoints and similar matters.

Master Service Agreement

On December 30, 2015, we entered into a Master Service Agreement with Covance, with an effective date of December 29, 2015. Pursuant to the terms of the Master Service Agreement, Covance (or one or more of its affiliates) will provide Phase 1, 2, 3, and 4 clinical services for a clinical study or studies to us, and, at our request, assist us with the design of such studies, in accordance with the terms of separate individual project agreements to be entered into by the parties. The term of the agreement is for three years and will renew automatically for successive one year periods unless Covance is no longer providing services under the agreement or either party has terminated the agreement upon written notice. We may terminate the Master Service Agreement or any individual project agreement entered into under the Master Service Agreement prior to the applicable study’s completion at any time for any reason upon 30 days written notice to Covance, except when the reason for termination is the safety of subjects, in which case it may be terminated immediately. Covance may not terminate any individual project agreement without cause, except when the reason for the termination is the safety of subjects, in which case it may be terminated immediately. In the event of a termination of the Master Service Agreement, Covance will be entitled to full payment for (i) work performed on the applicable project upon through the date work on such project is concluded and (ii) reimbursement for all non-cancellable and non-refundable expenses and financial obligations which Covance (or an affiliate) has incurred or undertaken on our behalf.

Manufacturing

We do not own or operate manufacturing facilities for the production of RP-G28 or any other product candidates we may develop, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We have an exclusive worldwide agreement (the “Supply Agreement”) to manufacture a higher purity form of GOS (referred to as “Improved GOS”) with Ricerche Sperimentali Montaleor (“RSM”) in connection with the clinical and nonclinical studies we will need to conduct prior to receiving regulatory approval for RPG-28. RSM has also agreed that it will not, except as necessary for RSM to perform its obligations under the Supply Agreement, market or sell Improved GOS, or any GOS that are of greater purity to any third party.

Pursuant to the terms of the Supply Agreement, as amended on July 24, 2015, we purchased the exclusive worldwide assignment of all right, title and interest to the Improved GOS (the “Improved GOS IP”) on July 30, 2015 for $800,000. We also issued 100,000 shares of our common stock to RSM pursuant to a stock purchase agreement. The shares issued to RSM are subject to a lock-up agreement, pursuant to which RSM has agreed that it will not sell these shares for a period ending on the earlier of (i) the public release by us of the final results of our Phase 2b/3 clinical trial of RP-G28 and (ii) the filing of a Form 10-Q with the SEC for the fiscal quarter in which we receive the results of our Phase 2b/3 clinical trial of RP-G28.

Under the terms of the Supply Agreement, as amended, if we fail to make any future option payment to RSM required under the terms of the Supply Agreement, we may be required to return the Improved GOS IP to RSM. The terms of the Supply Agreement, as amended, require us to pay RSM $400,000 within 10 days following FDA approval of a new drug application for the first product owned or controlled by us using Improved GOS as its active pharmaceutical ingredient and to pay RSM the sum of $250 per kilo for clinical supply of Improved GOS.

Commercialization

Given our stage of development, we have not yet established a commercial organization or distribution capabilities. RP-G28, if approved, is intended to be prescribed to patients suffering from lactose intolerance. These patients are normally under the care of a gastroenterologist and/or a primary care physician. Our current plan is to evaluate a possible partnership to commercialize RP-G28 for the reduction of symptoms associated with lactose intolerance in patients in the United States and Europe if it is approved. We may also build our own commercial infrastructure or utilize contract reimbursement specialists, sales people and medical education specialists, and take other steps to establish the necessary commercial infrastructure at such time as we believe that RP-G28 is approaching marketing approval. Outside of the United States and Europe, subject to obtaining necessary marketing approvals, we will likely seek to commercialize RP-G28 through distribution or other collaboration arrangements for patients suffering from lactose intolerance.

Competition

The biopharmaceutical industry is characterized by intense competition and rapid innovation. Although we know of no drug candidate, other than RP-G28, in advanced clinical trials for treating lactose intolerance, other biopharmaceutical companies may be able to develop compounds or drugs that are able to achieve similar or better results. Our potential competitors include major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies and universities and other research institutions. Some of the pharmaceutical and biotechnology companies we expect to compete with include microbiome-based development companies such as Second Genome, Inc., Seres Health, Inc., Enterome SA, Vedanta Biosciences, Inc., and Rebiotix, Inc. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. We will also compete with providers of a wide variety of lactase supplements (the most widely used supplement in the United States being Lactaid^®), probiotic/dietary supplements, and lactose-free and dairy-free products. We believe the key competitive factors that will affect the development and commercial success of our product candidates are efficacy, safety and tolerability profile, reliability, convenience of dosing, price and reimbursement.

Intellectual Property

The proprietary nature of, and protection for, our product candidates and our discovery programs, processes and know-how are important to our business. We have sought patent protection in the United States and internationally for uses of RP-G28 and our discovery programs, and any other inventions to which we have rights, where available and when appropriate. Our policy is to pursue, maintain and defend patent rights, whether developed internally or licensed from third parties, and to protect the technology, inventions and improvements that are commercially important to the development of our business. We also rely on trade secrets that may be important to the development of our business. We do not have composition of matter patent protection in the United States for RP-G28, which may result in competitors being able to offer and sell products so long as these competitors do not infringe any other patents that we hold, including patents directed to methods of manufacturing and purified RP-G28 or directed to methods of using RP-G28.

Patents and Proprietary Rights Covering Our Drug Candidates

We strive to protect our product candidates and exclusivity rights, as well as both maintain and fortify our position in the field of reduction of symptoms associated with lactose intolerance. We believe our intellectual property portfolio consists of early and broad filings in the area. We have focused on patents and patent applications relating to use of our products in disease treatment. We have sought and continue to seek the strongest possible intellectual property protection available to us in order to prevent others from directly competing with us, as well as to exclude competition around our products, their manufacture, and methods for use of the products in disease treatment. Our intellectual property portfolio related to RP-G28 contains four issued patents relating to RP-G28 and its uses. That portfolio also includes at least 15 other related, pending patent applications in the United States and worldwide. We also own a patent family, including claims generally directed to processes for producing an improved form of GOS mixtures (higher purity); this family includes issued patents in United States (not expiring until 2030), Italy (not expiring until 2029), and China, Germany, and the Netherlands (not expiring until 2030), as well as applications pending in the United States, Japan, India, and other jurisdictions that, if issued, will not expire until 2030.

This portfolio includes patents and proprietary rights related to:

We are pursuing patent applications. These applications are pending in the United States, Europe, Japan and other jurisdictions, and, if they issue as patents, will not expire until at least 2030, and include claims generally directed to (i) oral dosage forms of a higher purity GOS, (ii) use of GOS for treating lactose intolerance, and (iii) methods of preventing or reducing certain symptoms of lactose intolerance using GOS dosage forms. For example, we have paid issue fees (and expect patents to issue in due course) in two United States patent applications: one includes claims directed to an oral dosage forms comprising a prebiotic composition comprising 95% or more GOS by weight and less than 5% digestible saccharides by weight, in which the GOS comprises at least 45% by weight trisaccharides, and the other includes claims directed to oral dosage forms of GOS, comprising 0.1 to 10 g of a liquid GOS composition encapsulated in a gelatin capsule, in which the GOS composition comprises at least about 95% GOS by weight, less than about 5% digestible saccharides by weight, and at least 45% by weight trisaccharides.

Trade Secrets

In addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. Trade secrets and know-how can be difficult to protect. We seek to protect our proprietary processes, in part, by confidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and commercial partners. These agreements are designed to protect our proprietary information. We also seek to preserve the integrity and confidentiality of our data, trade secrets and know-how by maintaining physical security of our premises and physical and electronic security of our information technology systems.

Government Regulation and Product Approval

Governmental authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, labeling, packaging, promotion, storage, advertising, distribution, marketing and export and import of products such as those we are developing. Our product candidates must be approved by the FDA through the NDA process before they may be legally marketed in the United States and by the European Medicines Agency (the “EMA”) through the Marketing Authorization Application (“MAA”) process before they may be legally marketed in Europe. Our product candidates will be subject to similar requirements in other countries prior to marketing in those countries. The process of obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

United States Government Regulation

NDA Approval Processes

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (the “FDCA”) and implementing regulations. Failure to comply with the applicable U.S. requirements at any time during the product development process or approval process, or after approval, may subject an applicant to administrative or judicial sanctions, any of which could have a material adverse effect on us. These sanctions could include:

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

Once a pharmaceutical candidate is identified for development, it enters the preclinical or nonclinical testing stage. Nonclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies. An IND sponsor must submit the results of the nonclinical tests, together with manufacturing information and analytical data, to the FDA as part of the IND. Some nonclinical testing may continue even after the IND is submitted. In addition to including the results of the nonclinical studies, the IND will also include a protocol detailing, among other things, the objectives of the clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the first phase lends itself to an efficacy determination. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, places the IND on clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. A clinical hold may occur at any time during the life of an IND, and may affect one or more specific studies or all studies conducted under the IND.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCPs. They must be conducted under protocols detailing the objectives of the trial, dosing procedures, research subject selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND, and progress reports detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must timely report to FDA serious and unexpected adverse reactions, any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigation brochure, or any findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the drug. An institutional review board, or IRB, at each institution participating in the clinical trial must review and approve the protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form that must be provided to each research subject or the subject’s legal representative, monitor the study until completed and otherwise comply with IRB regulations.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Adaptive seamless phase 2b/3 designs, such as the Phase 2b/3 pivotal clinical trial for RP-G28 that we recently completed enrolling and dosing in October 2016, are aimed at interweaving the two phases of full development by combining them into one single, uninterrupted study conducted in two steps. Adaptive seamless phase 2b/3 designs enable a clinical trial to be conducted in steps with the sample size calculation selected on the basis of data observed in the first step to continue along to the second step. The main statistical challenge in such a design is ensuring control of the type I error rate. Most methodology for such trials is based on the same endpoint being used for interim and final analyses. A type I error is one in which the adaptation process leads to design, analysis, or conduct flaws that introduce bias that increases the chance of a false conclusion that a treatment is effective (a type I error). Controlling a type I error can be accomplished by prospectively specifying and including in the statistical analysis plan all possible adaptation plans that may be considered during the course of the trial. We have worked with our CRO to determine how best to control type I error in our Phase 2b/3 study.

Human clinical trials are inherently uncertain and Phase 1, Phase 2 and Phase 3 testing may not be successfully completed. The FDA or the sponsor may suspend a clinical trial at any time for a variety of reasons, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to the submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at other times may be requested. For instance, we held a Type C meeting with the FDA’s Division of Gastroenterology and Inborn Errors Products on February 20, 2013. The purpose of the meeting was to obtain the FDA’s feedback on the planned clinical development program and future necessary clinical studies, inform the FDA of our ongoing development plans, gain feedback on relevant clinical trial design and end points related to patient meaningful benefits, and to inform the FDA of the status of our product characterization. Following analysis of the Phase 2a clinical trial, discussions with the FDA during the Type C Meeting in early 2013 about our clinical development plan, and further discussions with our regulatory consultants, we initiated an adaptive design Phase 2b/3 clinical trial of RPG-28 in March 2016 and completed final enrollment and dosing in October 2016. As part of this process, we submitted a supplement to the IND detailing the protocols for the adaptive study.

We have had subsequent communications with FDA regarding our clinical program and regulatory path towards getting our product adequately studied and eventually approved. We intend to hold two meetings with the FDA in the near future about our Phase 2b/3 study, including a Type C meeting as well as an End of Phase 2 meeting, both of which the FDA has encouraged us to schedule. These meetings and communications are typical for development stage companies and include the clinical pathway, regulatory requirements, statistical plan and endpoints and similar matters.

FDA meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide advice on the next phase of development. Sponsors typically use the meeting at the end of Phase 2 to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 clinical trial that they believe will support the approval of the new drug.

Concurrent with clinical trials, sponsors usually complete additional animal safety studies and also develop additional information about the chemistry and physical characteristics of the drug and finalize a process for manufacturing commercial quantities of the product in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug and the manufacturer must develop methods for testing the quality, purity and potency of the drug. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its proposed shelf-life.

The results of product development, nonclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests and other control mechanisms, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the product. The submission of an NDA is subject to the payment of user fees, but a waiver of such fees may be obtained under specified circumstances. The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the agency’s threshold determination of whether it is sufficiently complete to permit substantive review. It may request additional information rather than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing.

Once the submission is accepted for filing, the FDA begins an in-depth review. NDAs receive either standard or priority review. A drug representing a significant improvement in treatment, prevention or diagnosis of disease may receive priority review. The FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical or other data. Even if such data are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant. The FDA may refer the NDA to an advisory committee for review and recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA, the FDA will inspect the facility or facilities where the product is manufactured and tested.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of FDA marketing approval of RP-G28, one of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND, and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the application for extension must be made prior to expiration of the patent. The United States Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we intend to apply for restorations of patent term for some of our currently owned or licensed patents to add patent life beyond their current expiration date, depending on the expected length of clinical trials and other factors involved in the submission of the relevant NDA.

Market exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application (“ANDA”), or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an approved NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA; however, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Pediatric Exclusivity and Pediatric Use

Under the Best Pharmaceuticals for Children Act (“BPCA”), certain drugs may obtain an additional six months of exclusivity, if the sponsor submits information requested in writing by the FDA (a Written Request) relating to the use of the active moiety of the drug in children. The FDA may not issue a Written Request for studies on unapproved or approved indications or where it determines that information relating to the use of a drug in a pediatric population, or part of the pediatric population, may not produce health benefits in that population.

We have not received a Written Request for such pediatric studies, although we may ask the FDA to issue a Written Request for such studies in the future. To receive the six-month pediatric market exclusivity, we would have to receive a Written Request from the FDA, conduct the requested studies in accordance with a written agreement with the FDA or, if there is no written agreement, in accordance with commonly accepted scientific principles, and submit reports of the studies. A Written Request may include studies for indications that are not currently in the labeling if the FDA determines that such information will benefit the public health. The FDA will accept the reports upon its determination that the studies were conducted in accordance with and are responsive to the original Written Request or commonly accepted scientific principles, as appropriate, and that the reports comply with the FDA’s filing requirements.

In addition, the Pediatric Research Equity Act (“PREA”) requires all applications (or supplements to an application) submitted under section 505 of the FDCA (21 U.S.C. §355) for a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration to contain a pediatric assessment unless the applicant has obtained a waiver or deferral. It also authorizes the FDA to require holders of approved NDAs for marketed drugs to conduct pediatric studies under certain circumstances. In general, PREA applies only to those drugs developed for diseases and/or conditions that occur in both the adult and pediatric populations. Products intended for pediatric-specific indications will be subject to the requirements of PREA only if they are initially developed for a subset of the relevant pediatric population.

As part of the Food and Drug Administration Safety and Innovation Act, Congress reauthorized both BPCA and PREA, which were slated to expire on September 30, 2012, and made both laws permanent.

Orphan Drugs

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States and when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that drug or biologic.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full NDA, to market the same product for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Orphan drug exclusive marketing rights in the United States also may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

We intend to explore orphan drug designation for RP-G28 for any orphan indication in which there is a medically plausible basis for treatment of the indication through colonic adaptation of gut bacteria.

Post-approval Requirements

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and approval. In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

Any drug products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things:

Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and some state agencies for compliance with cGMP and other laws.

We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products. Future FDA and state inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt production or distribution, or require substantial resources to correct.

From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes will be enacted, or FDA regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

Regulation Outside of the United States

In addition to regulations in the United States, we will be subject to regulations of other countries governing clinical trials and commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain approval by the comparable regulatory authorities of countries outside of the United States before we can commence clinical trials in such countries and approval of the regulators of such countries or economic areas, such as the European Union, before we may market products in those countries or areas. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA approval.

Under European Union regulatory systems, a company may submit marketing authorization applications either under a centralized or decentralized procedure. The centralized procedure, which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative disorders or diabetes and optional for those medicines which are highly innovative, provides for the grant of a single marketing authorization that is valid for all European Union member states. The decentralized procedure provides for mutual recognition of national approval decisions. Under this procedure, the holder of a national marketing authorization may submit an application to the remaining member states. Within 90 days of receiving the applications and assessments report, each member state must decide whether to recognize approval. If a member state does not recognize the marketing authorization, the disputed points are eventually referred to the European Commission, whose decision is binding on all member states.

Reimbursement

Sales of our products will depend, in part, on the extent to which the costs of our products will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. These third-party payors are increasingly challenging the prices charged for medical products and services. Additionally, the containment of healthcare costs has become a priority of federal and state governments and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. If these third-party payors do not consider our products to be cost-effective compared to other therapies, they may not cover our products after approved as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the “MMA”) imposed new requirements for the distribution and pricing of prescription drugs for Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs. Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand for our products for which we receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness of different treatments for the same illness. A plan for the research will be developed by the Department of Health and Human Services, the Agency for Healthcare Research and Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures will be made to Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is not clear what effect, if any, the research will have on the sales of any product, if any such product or the condition that it is intended to treat is the subject of a study. It is also possible that comparative effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of our product candidates. If third-party payors do not consider our products to be cost-effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act of 2010 (collectively, the “ACA”), enacted in March 2010, is a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. With regard to pharmaceutical products, among other things, the ACA is expected to expand and increase industry rebates for drugs covered under Medicaid programs and make changes to the coverage requirements under the Medicare Part D program. Although it is too early to determine the full effect of the ACA, the law appears likely to continue the pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs. In addition, some members of the U.S. Congress have been seeking to repeal in full or amend portions of the legislation and we expect they will continue to review and assess this legislation and alternative health care reform proposals. Ongoing Congressional efforts to repeal or amend the ACA, add to the uncertainty of the legislative changes enacted as part of the ACA.

In addition, in some non-U.S. jurisdictions, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products. Historically, products launched in the European Union do not follow price structures of the United States and generally tend to be significantly lower.

Item 1A. Risk Factors

We operate in a dynamic and rapidly changing business environment that involves multiple risks and substantial uncertainty. The following discussion addresses risks and uncertainties that could cause, or contribute to causing, actual results to differ from expectations in material ways. In evaluating our business, investors should pay particular attention to the risks and uncertainties described below and in other sections of this Annual Report and in our subsequent filings with the SEC. These risks and uncertainties, or other events that we do not currently anticipate or that we currently deem immaterial also may affect our results of operations, cash flows and financial condition. The trading price of our common stock could also decline due to any of these risks, and you could lose all or part of your investment. The following information should be read in conjunction with Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and related notes included in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report.

Risks Relating to Our Financial Position and Need for Additional Capital

We have incurred net losses in each year since our inception. Currently, we have no products approved for commercial sale. As a result, our ability to reduce our losses and reach profitability is unknown, and we may never achieve or sustain profitability.

We have incurred net losses in each year since our inception. The accompanying financial statements have been prepared assuming that we will continue as a going concern, which contemplates, among other things, the realization of assets and satisfaction of liabilities in the normal course of business. For the years ended December 31, 2016 and 2015, we had net losses of approximately $18.4 million and $8.8 million, respectively, and had net cash used in operating activities of approximately $15.2 million and $5.7 million, respectively. These net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

To date, we have devoted most of our financial resources to our corporate overhead and research and development, including our drug discovery research, preclinical development activities and clinical trials. We currently have no products that are approved for commercial sale. We expect to continue to incur net losses and negative operating cash flow for the foreseeable future, and we expect these losses to increase as we continue our development of, and seek regulatory approvals for, RP-G28, and other product candidates, prepare for and begin the commercialization of any approved products, and add infrastructure and personnel to support our product development efforts and operations as a public company. We anticipate that any such losses could be significant for the next several years as we complete our Phase 2b/3 and begin any Phase 3 clinical trials for RP-G28 for the reduction of symptoms associated with lactose intolerance and related activities required for regulatory approval of RP-G28. If RP-G28 does not gain regulatory approval, or does not achieve market acceptance, we may never become profitable, unless we are able to develop and market some other product. These net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. In addition, our expenses could increase if we are required by the FDA or the EMA, to perform studies or trials in addition to those currently expected, or if there are any delays in completing our clinical trials or the development of RP-G28, or any other product candidate we may develop in the future. The amount of future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues.

We will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our operations.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. As of December 31, 2016, we have a total of approximately $7.0 million in cash.

On June 29, 2015, we closed our initial public offering of 4,000,000 shares of common stock at a public offering price of $5.00 per share. Total gross proceeds from our initial public offering were $20.0 million before deducting underwriting discounts and commissions and other offering expenses payable by us, resulting in net proceeds of $17.4 million.

On December 18, 2015, we entered into a common stock purchase agreement (the “Aspire Purchase Agreement”) with Aspire Capital Fund, LLC (“Aspire Capital”), which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $10.0 million of our shares of common stock over the approximately 30-month term of the Aspire Purchase Agreement. As of the date of this Annual Report, we have sold 1,577,699 shares of common stock to Aspire Capital for proceeds of $3.0 million.

On October 31, 2016, we closed a public offering of 2,127,660 shares of our common stock at a price to the public of $2.35 per share, for net proceeds of approximately $4.4 million, after deducting underwriting discounts and commissions and offering expenses payable by us in the offering.

We expect our existing cash and cash equivalents, together with interest, and any proceeds received from our sale of shares of common stock to Aspire Capital in the future pursuant to the Aspire Purchase Agreement, will be sufficient to fund our current operations through 2017. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. For example, our clinical trials may encounter technical, enrollment or other difficulties that could increase our development costs more than we expect.

We do not expect our existing capital resources will be sufficient to enable us to complete the commercialization of RP-G28, if approved, or to initiate any clinical trials or additional development work for other product candidates, other than as described above. We will need to secure additional financing in order to complete clinical development and commercialize RP-G28 and to generally fund our operations. To complete the work necessary to file a NDA and a MAA for RP-G28 as a treatment for patients with lactose intolerance, which is currently anticipated to occur in 2019, we estimate that our RP-G28 clinical trials, and our planned clinical and nonclinical studies, as well as other work needed to submit RP-G28 for regulatory approval in the United States, Europe and other countries, will cost approximately $85 million, including the internal resources needed to manage the program. If the FDA or EMA requires that we perform additional nonclinical studies or clinical trials, our expenses would further increase beyond what we currently expect and the anticipated timing of any potential NDA or MAA would likely be delayed.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail one or more of our research or development programs. We also could be required to seek funds through arrangements with collaborative partners or otherwise that may require us to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us.

The extent to which we utilize the Aspire Purchase Agreement with Aspire Capital as a source of funding will depend on a number of factors, including the prevailing market price of our common stock, the volume of trading in our common stock and the extent to which we are able to secure funds from other sources. The number of shares that we may sell to Aspire Capital under the Aspire Purchase Agreement on any given day and during the term of the agreement is limited. Additionally, we and Aspire Capital may not effect any sales of shares of our common stock under the Aspire Purchase Agreement during the continuance of an event of default or on any trading day that the closing sale price of our common stock is less than $0.50 per share. Even if we are able to access the full $10 million under the Aspire Purchase Agreement, we will still need additional capital to fully implement our business, operating and development plans.

We may sell additional equity or debt securities to fund our operations, which would result in dilution to our stockholders and imposed restrictions on our business.

We may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. Additional funding may not be available to us on acceptable terms or at all. To the extent that we raise additional funds by issuing equity securities (including any common stock issued to Aspire Capital pursuant to the Aspire Purchase Agreement), our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that impact our ability to conduct business. If we are not able to raise additional capital when required or on acceptable terms, we may have to (i) significantly delay, scale back or discontinue the development and/or commercialization of one or more product candidates; (ii) seek collaborators for product candidates at an earlier stage than otherwise would be desirable and on terms that are less favorable than might otherwise be available; or (iii) relinquish or otherwise dispose of rights to technologies, product candidates or products that we would otherwise seek to develop or commercialize. In addition, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional shares by us, or the possibility of such issuance, may cause the market price of our shares to decline.

Our financial condition and operating results have varied significantly since our formation and are expected to continue to fluctuate significantly from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control.

Our operations since 2010 have been limited to developing our technology and undertaking preclinical studies and clinical trials of our lead product candidate, RP-G28. We have not yet obtained regulatory approvals for RP-G28, or any other product candidate. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had approved products on the market. Our financial condition and operating results have varied significantly since our formation and are expected to continue to significantly fluctuate from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include:

Accordingly, the results of any quarterly or annual periods should not be relied upon as indications of future operating performance.

Risks Relating to Regulatory Review and Approval of Our Product Candidates

We are substantially dependent on the success of RP-G28.

We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. We currently invest nearly all of our efforts and financial resources in the research and development of RP-G28, which is currently our only product candidate. Our business currently depends entirely on the successful development and commercialization of RP-G28.

We cannot be certain that RP-G28 will receive regulatory approval, and without regulatory approval we will not be able to market RP-G28 as a prescription drug.

The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by the FDA in the United States, the EMA in Europe, and regulatory authorities in other countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States or Europe until we receive approval of a NDA from the FDA or a MAA from the EMA, respectively. We have not submitted any marketing applications for RP-G28.

NDAs and MAAs must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. NDAs and MAAs must also include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of a NDA or a MAA is a lengthy, expensive and uncertain process, and we may not be successful in obtaining approval. The FDA and the EMA review processes can take years to complete and approval is never guaranteed. If we submit a NDA to the FDA, the FDA must decide whether to accept or reject the submission for filing. We cannot be certain that any submissions will be accepted for filing and review by the FDA. Regulators of other jurisdictions, such as the EMA, have their own procedures for approval of product candidates. Even if a product is approved, the FDA or the EMA, as the case may be, may limit the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming clinical trials or reporting as conditions of approval. Regulatory authorities in countries outside of the United States and Europe also have requirements for approval of drug candidates with which we must comply prior to marketing in those countries. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able to obtain regulatory approval in any other country. In addition, delays in approvals or rejections of marketing applications in the United States, Europe or other countries may be based upon many factors, including regulatory requests for additional analyses, reports, data, preclinical studies and clinical trials, regulatory questions regarding different interpretations of data and results, changes in regulatory policy during the period of product development and the emergence of new information regarding our product candidates or other products. Also, regulatory approval for any product candidates may be withdrawn.

We have completed one Phase 2a trial and an adaptive design Phase 2b/3 clinical trial for RP-G28. Before we submit a NDA to the FDA or a MAA to the EMA for RP-G28 for the treatment of pain and the reduction in the frequency of symptomatic episodes of lactose intolerance, we must successfully complete a Phase 2b/3 trial and Phase 3 trials. Following analysis of the Phase 2a clinical trial, discussions with the FDA during the Type C meeting in 2013 about our clinical development plan, and further discussions with our regulatory consultants, we initiated an adaptive design Phase 2b/3 clinical trial of RPG-28 in March 2016. A trial that is designed as an adaptive seamless clinical trial refers to a trial that combines the objectives of what are typically separate trials into a single uninterrupted trial with multiple objectives.

Regulatory authorities in the United States and Europe have both published guidance documents on the use and implementation of adaptive design trials. These documents include description of adaptive trials and include a requirement for prospectively written standard operating procedures and working processes for executing adaptive trials and a recommendation that sponsor companies engage with CROs that have the necessary experience in running such trials. In addition, the regulations governing INDs are extensive and involve numerous notification requirements including that, generally, an IND supplement must be submitted to and cleared by the FDA before a sponsor or an investigator may make any change to the investigational plan that may affect its scientific soundness or the rights, safety or welfare of human subjects. We intend to comply with these requirements. We submitted an IND supplement containing amended protocols for the Phase 2b/3 adaptive trial, and have had subsequent communications with FDA regarding our clinical program and regulatory path towards getting our product adequately studied and eventually approved. We intend to hold two meetings with the FDA in the near future about our Phase 2b/3 study, including a Type C meeting as well as an End of Phase 2 meeting, both of which the FDA has encouraged us to schedule. These meetings and communications are typical for development stage companies and include the clinical pathway, regulatory requirements, statistical plan and endpoints and similar matters. There can be no assurance that this trial and other trials will not be delayed or disrupted as a result of our current development plan.

In addition, guidelines adopted by the FDA and established by the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) require nonclinical studies that specifically address female fertility to be completed before the inclusion of women of child bearing potential in large-scale or long-duration clinical trials (e.g., Phase 3 trials). In the United States, such assessments of embryo-fetal development can be deferred until before Phase 3 using precautions to prevent pregnancy in clinical trials. As the FDA recommended in their June 28, 2010 advice letter, we will continue to evaluate females of child-bearing potential who are willing to use appropriate contraception throughout the duration of any study. We cannot predict whether our future trials and studies will be successful or whether regulators will agree with our conclusions regarding the preclinical studies and clinical trials we have conducted to date.

If we are unable to obtain approval from the FDA, the EMA or other regulatory agencies for RP-G28, or if, subsequent to approval, we are unable to successfully commercialize RP-G28, we will not be able to generate sufficient revenue to become profitable or to continue our operations.

Any statements in this document indicating that RP-G28 has demonstrated preliminary evidence of efficacy are our own and are not based on the FDA’s or any other comparable governmental agency’s assessment of RP-G28 and do not indicate that RP-G28 will achieve favorable efficacy results in any later stage trials or that the FDA or any comparable agency will ultimately determine that RP-G28 is effective for purposes of granting marketing approval.

The FDA and other regulatory agencies outside the United States, such as the EMA, may not agree to our proposed endpoint for approval of RP-G28 for the reduction of symptoms associated with lactose intolerance in patients, in which case we would need to complete an additional clinical trial in order to seek approval outside the United States.

During our Type C Meeting with the FDA in February 2013, we had proposed that future studies with RP-G28 in subjects with lactose intolerance would utilize a total lactose intolerance symptom score, measured by a patient reporting instrument that we were going to develop, as the primary, stand-alone endpoint. However, based on RP-G28’s mechanism of action, data from the Phase 2a clinical study, further research conducted after the Type C Meeting with the FDA along with FDA guidance and products under the review of the Division of Gastroenterology and Inborn Errors Products, we used abdominal pain, measured by the Patient Assessment of Adequate Relief Item instrument administered monthly, as the primary endpoint for the Phase 2b/Phase 3 study that assessed RP-G28 for the management of lactose intolerant patients with moderate to severe abdominal pain associated with lactose intake. We believe that evaluation of abdominal pain is a reliable clinical assessment of treatment response and treatment benefit in a lactose intolerant patient. Although no FDA-approved product exists for lactose intolerance, the use of a pain scale as a primary endpoint has been used as a validated primary measurement in many approved products, including other gastrointestinal products used to treat diseases such as Irritable Bowel Syndrome (IBS). We did not consult with the FDA about our intent to use abdominal pain as a primary endpoint. We also did not discuss the Phase 2b/3 study design and development plan with the FDA before initiating the study in March 2016, though we did submit a supplement to the IND detailing the protocols for the adaptive study. We intend to hold two meetings with the FDA in the near future about our Phase 2b/3 study, including a Type C meeting as well as an End of Phase 2 meeting, both of which the FDA has encouraged us to schedule.

We do not know if the FDA, the EMA or regulatory authorities in other countries will agree with our final primary endpoint for approval of RP-G28. The FDA, the EMA and regulatory authorities in other countries in which we may seek approval for and market RP-G28, may require additional nonclinical studies and/or clinical trials prior to granting approval. It may be expensive and time consuming to conduct and complete additional nonclinical studies and clinical trials that the EMA and other regulatory authorities may require us to perform. As such, any requirement by the EMA or other regulatory authorities that we conduct additional nonclinical studies or clinical trials could materially and adversely affect our business, financial condition and results of operations. Furthermore, even if we receive regulatory approval of RP-G28 for the reduction of symptoms associated with lactose intolerance in patients, the labeling for RP-G28 in the United States, Europe or other countries in which we seek approval may include limitations that could impact the commercial success of RP-G28.

The results from our planned Phase 2b/3 trial with adaptive design may not be sufficiently robust to support the submission of marketing approval for RP-G28.

We conducted our Phase 2b clinical trial as an adaptive design seamless Phase 2b/3 clinical trial. We did not meet with the FDA to discuss the Phase 2b/3 study design or the development plan for RP-G28 before initiating the Phase 2b/3 study in march 2016. The FDA standard for traditional approval of a drug generally requires two well-controlled Phase 3 studies. If the FDA disagrees with our choice of primary endpoint for our Phase 2b/3 trial or the results for the primary endpoint are not robust or significant relative to control, are subject to confounding factors, or are not adequately supported by other study endpoints, the FDA may not recognize the Phase 2b/3 trial as one of the required pivotal trials required for FDA approval. If the FDA or other regulatory authorities do not recognize this trial as a pivotal trial, we would incur increased costs and delays in the marketing approval process, which would require us to expend more resources than we have available.

Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for RP-G28 or our other product candidates we may develop in the future.

Delays in the commencement, enrollment and completion of clinical trials could increase our product development costs or limit the regulatory approval of RP-G28 or other product candidates we may develop in the future. Although we believe that our existing cash and cash equivalents, together with interest, and any proceeds received from our sale of shares of common stock to Aspire Capital in the future pursuant to the pursuant to the Aspire Purchase Agreement should be sufficient to fund our projected operating requirements through the completion of the Phase 2b/3 and the design of any Phase 3 trials of RP-G28, we may not be able to complete these trials on time or we may be required to conduct additional clinical trials or nonclinical studies not currently planned to receive approval for RP-G28 as a treatment for lactose intolerance. The commencement, enrollment and completion of clinical trials may be delayed or suspended for a variety of reasons, including:

Changes in regulatory requirements and guidance may also occur and we may need to amend clinical trial protocols to reflect these changes with appropriate regulatory authorities. Amendments may require us to resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. In addition, a clinical trial may be suspended or terminated at any time by us, our future collaborators, the FDA or other regulatory authorities due to a number of factors, including:

In addition, if we or any of our potential future collaborators are required to conduct additional clinical trials or other nonclinical studies of our product candidates beyond those contemplated, our ability to obtain regulatory approval of these product candidates and to generate revenue from their sales would be similarly harmed.

Clinical failure can occur at any stage of clinical development. The results of earlier clinical trials are not necessarily predictive of future results and any product candidate we or our potential future collaborators advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval.

Clinical failure can occur at any stage of our clinical development. Clinical trials may produce negative or inconclusive results, and we or our collaborators may decide, or regulators may require us, to conduct additional clinical trials or nonclinical studies. In addition, data obtained from trials and studies are susceptible to varying interpretations, and regulators may not interpret our data as favorably as we do, which may delay, limit or prevent regulatory approval. Success in preclinical studies and early clinical trials does not ensure that subsequent clinical trials will generate the same or similar results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in Phase 2b and/or Phase 3 clinical trials, including adaptive seamless clinical trials even after seeing promising results in earlier clinical trials.

In addition, the design of a clinical trial can determine whether its results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well-advanced. We may be unable to design and execute a clinical trial to support regulatory approval. Further, clinical trials of potential products often reveal that it is not practical or feasible to continue development efforts.

If RP-G28, or any of the other product candidates that we may develop in the future, is found to be unsafe or lack efficacy, we will not be able to obtain regulatory approval for it and our business would be harmed. For example, if the results of our Phase 2b/3 and any Phase 3 trials of RP-G28 do not achieve the primary efficacy endpoints or demonstrate expected safety, the prospects for approval of RP-G28 would be materially and adversely affected.

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in composition of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. We do not know whether any Phase 2, Phase 3 or other clinical trials we or any of our potential future collaborators may conduct will demonstrate the consistent or adequate efficacy and safety that would be required to obtain regulatory approval and market RP-G28. Our adaptive Phase 2b/3 clinical trial for RP-G28 may not be deemed to be a pivotal trial by the FDA or may not provide sufficient support for NDA approval. The FDA may require us to make changes to the proposed study design for this adaptive trial or may require us to conduct one or more additional clinical trials, possibly involving a larger sample size or a different clinical trial design, or may require longer follow-up periods, particularly if the FDA does not find the results from our adaptive Phase 2b/3 clinical trial to be sufficiently persuasive as one of the required pivotal trials required for FDA approval. If we are unable to bring RP-G28 to market, our ability to create long-term stockholder value will be limited.

Our product candidates may have undesirable side effects which may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales.

Unforeseen side effects from RP-G28, or other product candidates we may develop in the future, could arise either during clinical development or, if approved, after the approved product has been marketed. The most common side effects observed in clinical trials of RP-G28 were headache (nine out of 57), nausea (three out of 57), upper respiratory tract infection (two of 57), nasal congestion (two of 57), and pain (two out of 57). No patients were withdrawn from our Phase 2b/3 clinical trial for these side effects.

Any undesirable or unacceptable side effects associated with our product candidates could interrupt, delay or halt clinical trials, and result in delay of, or failure to obtain, marketing approval from the FDA and other regulatory authorities.

In addition:

Any of these events could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products.

Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance. If there is not sufficient reimbursement for our products, it is less likely that they will be widely used.

Market acceptance and sales of RP-G28, or any other product candidates we may develop in the future, if approved, will depend on reimbursement policies and may be affected by, among other things, future healthcare reform measures. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for RP-G28 or any other product candidates that we may develop. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, our products. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize RP-G28, or other product candidates that we develop.

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the “MMA”), changed the way Medicare covers and pays for pharmaceutical products. The legislation established Medicare Part D, which expanded Medicare coverage for outpatient prescription drug purchases by the elderly but provided authority for limiting the number of drugs that will be covered in any therapeutic class. The MMA also introduced a new reimbursement methodology based on average sales prices for physician-administered drugs. Any negotiated prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain in the United States. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

The United States and several other jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. We expect to experience pricing pressures in connection with the sale of RP-G28, and any other product candidates that we develop, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act of 2010 (collectively, the “ACA”), enacted in March 2010, is a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. With regard to pharmaceutical products, among other things, the ACA is expected to expand and increase industry rebates for drugs covered under Medicaid programs and make changes to the coverage requirements under the Medicare Part D program. Although it is too early to determine the full effect of the ACA, the law appears likely to continue the pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs. In addition, some members of the U.S. Congress have been seeking to repeal in full or amend portions of the legislation and we expect they will continue to review and assess this legislation and alternative health care reform proposals. Ongoing Congressional efforts to repeal or amend the ACA, add to the uncertainty of the legislative changes enacted as part of the ACA.

If we do not obtain protection under the Hatch-Waxman Act and similar legislation outside of the United States by extending the patent terms and obtaining data exclusivity for our product candidates, our business may be materially harmed.

Depending upon the timing, duration and specifics of FDA marketing approval of RP-G28, one of our U.S. patents may be eligible for a limited Patent Term Extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (which is sometimes referred to as the “Hatch-Waxman Act”), provided our U.S. patent claims a method of treating lactose intolerance that is approved by the FDA. The Hatch-Waxman Act, 35 U.S.C. §156, permits a patent extension of up to five years as compensation for patent term lost during the FDA regulatory review process. The scope of protection afforded by the patent during the extended term is not commensurate with the scope of the unextended portion of the patent; for example, the “rights derived” from a method of use patent during the extended period are “limited to any use claimed by the patent and approved for the product.” 35 U.S.C. §156(b)(2). We may not be granted an extension because of, for example, failing to apply for the extension within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable statutory and/or regulatory requirements including, for example, the requirement that the patent to be extended “claim” the approved product or a method of using the approved product. Moreover, the applicable period of extension could be less than we request. If we are unable to obtain patent term extension or if the term of any such extension is shorter than we request, the period during which we will be able to exclude others from marketing their versions of our product will be shortened and our competitors may obtain approval of generic products following our patent expiration, and our revenue could be reduced, possibly materially. Similar concerns are associated with obtaining Supplemental Protection Certificates (SPCs) of certain patents issued in Europe and owned by Inalco, to which we have an exclusive options of assignment, based upon patent terms lost during European regulatory review processes. In the event that we are unable to obtain any patent term extension, the issued patents for RP-G28 are expected to expire in 2030, assuming they withstand any challenge toothier validity and/or patentability.

If we market products in a manner that violates healthcare fraud and abuse laws, or if we violate government price reporting laws, we may be subject to civil or criminal penalties.

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal healthcare laws, commonly referred to as “fraud and abuse” laws, have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. Other jurisdictions such as Europe have similar laws. These laws include false claims and anti-kickback statutes. If we market our products and our products are paid for by governmental programs, it is possible that some of our business activities could be subject to challenge under one or more of these laws.

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid. The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service covered by Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers or formulary managers on the other. Although there are several statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Most states also have statutes or regulations similar to the federal anti-kickback law and federal false claims laws, which apply to items and services covered by Medicaid and other state programs, or, in several states, apply regardless of the payor. Administrative, civil and criminal sanctions may be imposed under these federal and state laws.

Over the past few years, a number of pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of promotional and marketing activities, such as: providing free trips, free goods, sham consulting fees and grants and other monetary benefits to prescribers; reporting inflated average wholesale prices that were then used by federal programs to set reimbursement rates; engaging in off-label promotion; and submitting inflated best price information to the Medicaid Rebate Program to reduce liability for Medicaid rebates.

Any delay or disruption in the manufacture and supply of RP-G28 may negatively impact our operations.

We do not intend to manufacture the pharmaceutical products that we plan to sell. We have an agreement with RSM, our contract manufacturer, for the production of Improved GOS, the active pharmaceutical ingredient in RP-G28, and the formulation of sufficient quantities of Improved GOS for the clinical and nonclinical studies that we believe we will need to conduct prior to seeking regulatory approval for RPG-28. However, we do not have agreements for commercial supplies of RP-G28 and we may not be able to reach agreements with these or other contract manufacturers for sufficient supplies to commercialize RP-G28 if it is approved.

Reliance on third-party manufacturers entails risks, to which we would not be subject if we manufactured the product candidates ourselves, including:

Any of these factors could cause the delay of approval or commercialization of our product candidates, cause us to incur higher costs or prevent us from commercializing our product candidates successfully. Furthermore, if RP-G28 or other product candidates are approved and contract manufacturers fail to deliver the required commercial quantities of finished product on a timely basis and at commercially reasonable prices and we are unable to find one or more replacement manufacturers capable of production at a substantially equivalent cost, in substantially equivalent volumes and quality and on a timely basis, we would likely be unable to meet demand for our products and could lose potential revenue. It may take several years to establish an alternative source of supply for our product candidates and to have any such new source approved by the government agencies that regulate our products. In the event we do need to identify alternative manufacturing partners, we may have to secure licenses to manufacturing and/or purification technologies, including third-party patent licenses, to allow us to manufacture RP-G28 that is suitable for the late-stage regulatory review process and/or adequate to manufacture commercial quantities of RP-G28.

If the FDA and EMA and other regulatory agencies do not approve the manufacturing facilities of our future contract manufacturers for commercial production, we may not be able to commercialize any of our product candidates.

The facilities used by any contract manufacturer to manufacture RP-G28, or other product candidates we may develop in the future, must be the subject of a satisfactory inspection before the FDA or the regulators in other jurisdictions approve the product candidate manufactured at that facility. We are completely dependent on these third-party manufacturers for compliance with the requirements of U.S. and non-U.S. regulators for the manufacture of our finished products. If our manufacturers cannot successfully manufacture material that conform to our specifications and current good manufacturing practice requirements of any governmental agency whose jurisdiction to which we are subject, our product candidates will not be approved or, if already approved, may be subject to recalls.

Even if our product candidates receive regulatory approval, we may still face future development and regulatory difficulties.

RP-G28 and any other product candidates we develop in the future, if approved, will be subject to ongoing regulatory requirements for labeling, packaging, storage, advertising, promotion, record-keeping and submission of safety and other post-market information. In addition, approved products, manufacturers and manufacturers’ facilities are required to comply with extensive FDA and EMA requirements and requirements of other similar agencies, including ensuring that quality control and manufacturing procedures conform to current cGMPs. As such, we and our contract manufacturers are subject to continual review and periodic inspections to assess compliance with cGMPs. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control. We will also be required to report certain adverse reactions and production problems, if any, to the FDA and EMA and other similar agencies and to comply with certain requirements concerning advertising and promotion for our products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. Accordingly, we may not promote our approved products, if any, for indications or uses for which they are not approved.

If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, it may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If our product candidates fail to comply with applicable regulatory requirements, a regulatory agency may:

Risks Relating to the Commercialization of Our Products

Even if approved, our product candidates may not achieve broad market acceptance among physicians, patients and healthcare payors, and as a result our revenues generated from their sales may be limited.

The commercial success of RP-G28, if approved, will depend upon its acceptance among the medical community, including physicians, health care payors and patients. The degree of market acceptance of RP-G28, or other product candidates we may develop in the future, will depend on a number of factors, including:

If our product candidates are approved, but do not achieve an adequate level of acceptance by physicians, patients, the medical community and healthcare payors, sufficient revenue may not be generated from these products and we may not become or remain profitable. In addition, efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may never be successful.

We have no internal sales, distribution and/or marketing capabilities at this time and we will have to invest significant resources to develop those capabilities or enter into acceptable third-party sales and marketing arrangements.

We have no internal sales, distribution and/or marketing capabilities at this time. To develop these capabilities, we will have to invest significant amounts of financial and management resources, some of which will be committed prior to any confirmation that RP-G28 will be approved. For product candidates for which we decide to perform sales, marketing and distribution functions ourselves or through third parties, we could face a number of additional risks, including:

We may have limited or no control over the sales, marketing and distribution activities of these third parties. Our future revenues may depend heavily on the success of the efforts of these third parties.

We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop RP-G28 or other product candidates and our financial condition and operating results.

Because developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities and marketing approved products are expensive, we may seek to enter into collaborations with companies that have more experience. Additionally, if RP-G28, or any other product candidate we develop in the future, receives marketing approval, we may enter into sales and marketing arrangements with third parties with respect to our unlicensed territories. If we are unable to enter into arrangements on acceptable terms, we may be unable to effectively market and sell our products in our target markets. We expect to face competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time consuming to negotiate, document and implement and they may require substantial resources to maintain. We may not be successful in our efforts to establish and implement collaborations or other alternative arrangements for the development of our product candidates.

When we collaborate with a third party for the development and commercialization of a product candidate, we can expect to relinquish some or all of the control over the future success of that product candidate to the third party. For example, we may relinquish the rights to RP-G28 in jurisdictions outside of the United States. Our collaboration partner may not devote sufficient resources to the commercialization of our product candidates or may otherwise fail in their commercialization. The terms of any collaboration or other arrangement that we establish may not be favorable to us. In addition, any collaboration that we enter into may be unsuccessful in the development and commercialization of our product candidates. In some cases, we may be responsible for continuing preclinical and initial clinical development of a product candidate or research program under a collaboration arrangement, and the payment we receive from our collaboration partner may be insufficient to cover the cost of this development. If we are unable to reach agreements with suitable collaborators for our product candidates, we would face increased costs, we may be forced to limit the number of our product candidates we can commercially develop or the territories in which we commercialize them and we might fail to commercialize products or programs for which a suitable collaborator cannot be found. If we fail to achieve successful collaborations, our operating results and financial condition will be materially and adversely affected.

Risks Relating to Our Business and Strategy

We may face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.

Although we know of no other drug candidates in advanced clinical trials for treating lactose intolerance, the biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. We have potential competitors in the United States, Europe and other jurisdictions, including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical and generic drug companies and universities and other research institutions. Many of these potential competitors have greater financial and other resources, such as larger research and development staff and more experienced marketing and manufacturing organizations. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. These companies also have significantly greater research, sales and marketing capabilities and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. As a result of all of these factors, these potential competitors may succeed in obtaining patent protection and/or FDA approval or discovering, developing and commercializing drugs for the diseases that we are targeting before we do. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Some of the pharmaceutical and biotechnology companies we expect to compete with include microbiome based development companies: Second Genome, Inc., Seres Health, Inc., Enterome SA, Vedanta Biosciences, Inc., and Rebiotix Inc. In addition, many universities and private and public research institutes may become active in our target disease areas. These potential competitors may succeed in developing, acquiring or licensing on an exclusive basis, technologies and drug products that are more effective or less costly than RP-G28 or any other product candidates that we are currently developing or that we may develop, which could render our products obsolete and noncompetitive.

We believe that our ability to successfully compete will depend on, among other things:

If our competitors market products that are more effective, safer or less expensive than ours, or that reach the market sooner than ours, we may not achieve commercial success. In addition, the biopharmaceutical industry is characterized by rapid technological change. Because our research approach integrates many technologies, it may be difficult for us to stay abreast of the rapid changes in each technology. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or product candidates obsolete, less competitive or not economical.

We depend on third-party contractors for a substantial portion of our operations and may not be able to control their work as effectively as if we performed these functions ourselves.

We outsource substantial portions of our operations to third-party service providers, including the conduct of preclinical studies and clinical trials, collection and analysis of data, and manufacturing. Our agreements with third-party service providers and CROs are on a study-by-study and project-by-project basis. Typically, we may terminate the agreements with notice and are responsible for the supplier’s previously incurred costs. In addition, any CRO that we retain will be subject to the FDA’s and EMA’s regulatory requirements and similar standards outside of the United States and Europe and we do not have control over compliance with these regulations by these providers. Consequently, if these providers do not adhere to applicable governing practices and standards, the development and commercialization of our product candidates could be delayed or stopped, which could severely harm our business and financial condition.

Because we have relied on third parties, our internal capacity to perform these functions is limited to management oversight. Outsourcing these functions involves the risk that third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. Although we have not experienced any significant difficulties with our third-party contractors, it is possible that we could experience difficulties in the future. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated. There are a limited number of third-party service providers that specialize or have the expertise required to achieve our business objectives. Identifying, qualifying and managing performance of third-party service providers can be difficult, time consuming and cause delays in our development programs. We currently have a small number of employees, which limits the internal resources we have available to identify and monitor third-party service providers. To the extent we are unable to identify, retain and successfully manage the performance of third-party service providers in the future, our business may be adversely affected, and we may be subject to the imposition of civil or criminal penalties if their conduct of clinical trials violates applicable law.

We may enter into agreements with other third parties for the development and commercialization of RP-G28, or other product candidates we develop in the future, in international markets. International business relationships subject us to additional risks that may materially adversely affect our ability to attain or sustain profitable operations, including:

We will need to expand our operations and increase the size of our company, and we may experience difficulties in managing growth.

As we increase the number of ongoing product development programs and advance our product candidates through preclinical studies and clinical trials, we will need to increase our product development, scientific and administrative headcount to manage these programs. In addition, to meet our obligations as a public company, we will need to increase our general and administrative capabilities. Our management, personnel and systems currently in place may not be adequate to support this future growth. Our need to effectively manage our operations, growth and various projects requires that we:

If we are unable to successfully manage this growth and increased complexity of operations, our business may be adversely affected.

We may not be able to manage our business effectively if we are unable to attract and retain key personnel and consultants.

We may not be able to attract or retain qualified management, finance, scientific and clinical personnel and consultants due to the intense competition for qualified personnel and consultants among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain necessary personnel and consultants to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.

We are highly dependent on the development, regulatory, commercialization and business development expertise of Michael D. Step, our Chief Executive Officer, Andrew J. Ritter, our Founder and President, and Ira E. Ritter, our Executive Chairman and Chief Strategic Officer. If we were to lose one or more of these key employees, our ability to implement our business strategy successfully could be seriously harmed. Any of our executive officers may terminate their employment at any time. Replacing any of these persons would be difficult and could take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to develop, gain regulatory approval of and commercialize products successfully.

There is also a risk that other obligations could distract our officers and employees from our business, which could have negative impact on our ability to effectuate our business plans.

In addition, we have scientific and clinical advisors and consultants who assist us in formulating our research, development and clinical strategies. Competition to hire and retain consultants from a limited pool is intense. Further, because these advisors are not our employees, they may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us, and typically they will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

If we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately report our financial condition, results of operations or cash flows, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

The Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and procedures. Commencing with this Annual Report, we are required, under Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. This assessment must include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. A material weakness is a control deficiency, or combination of control deficiencies, in internal control over financial reporting that results in more than a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis. Section 404 of the Sarbanes-Oxley Act also generally requires an attestation from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting. However, for as long as we remain an emerging growth company, as defined in the JOBS Act, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm’s requirement to attest to the effectiveness of our internal controls over financial reporting.

Our compliance with Section 404 will require that we incur substantial accounting expense and expend significant management efforts. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting once that firm begin its Section 404 reviews, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the NASDAQ stock market, the SEC, or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We are subject to the periodic reporting requirements of the Exchange Act. Our disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements or insufficient disclosure due to error or fraud may occur and not be detected.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading, which could significantly harm our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators, provide accurate information to the FDA and non-U.S. regulators, comply with health care fraud and abuse laws and regulations in the United States and abroad, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the health care industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted an employee handbook, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for a product candidate and may have to limit its commercialization.

The use of our product candidates in clinical trials and the sale of any products for which we may obtain marketing approval expose us to the risk of product liability claims. Product liability claims may be brought against us or our potential future collaborators by participants enrolled in our clinical trials, patients, health care providers or others using, administering or selling our products. If we cannot successfully defend ourselves against any such claims, we would incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

We have product liability insurance coverage for our Phase 2b/3 clinical trials in the United States and in selected other jurisdictions where we intend to conduct clinical trials at levels we believe are sufficient and consistent with industry standards for companies at our stage of development. However, our insurance coverage may not reimburse us or may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to product liability. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against us, particularly if judgments exceed our insurance coverage, could decrease our cash resources and adversely affect our business.

Our insurance policies are expensive and only protect us from some business risks, which will leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability ($2.0 million coverage), employment practices liability, workers’ compensation, and directors’ and officers’ insurance at levels we believe are typical for a company in our industry and at our stage of development. We currently carry clinical trial liability insurance for our Phase 2b/3 clinical trials at levels we believe are sufficient and consistent with industry standards for companies at our stage of development. We do not know, however, if we will be able to maintain insurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our financial position and results of operations.

If we engage in an acquisition, reorganization or business combination, we will incur a variety of risks that could adversely affect our business operations or our stockholders.

From time to time we have considered, and we will continue to consider in the future, strategic business initiatives intended to further the expansion and development of our business. These initiatives may include acquiring businesses, technologies or products or entering into a business combination with another company. If we pursue such a strategy, we could, among other things:

Although we intend to evaluate and consider acquisitions, reorganizations and business combinations in the future, we have no agreements or understandings with respect to any acquisition, reorganization or business combination at this time.

Risks Relating to Our Intellectual Property

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection. If our patent position does not adequately protect our product candidates, others could compete against us more directly, which would harm our business, possibly materially.

Our commercial success will depend in part on obtaining, maintaining and enforcing patent protection and on developing, preserving and enforcing current trade secret protection. In particular, it will depend in part on our ability to obtain, maintain and enforce patents, especially those related to methods of using our current product, RP-G28, and other future drug candidates, and those related to the methods used to develop and manufacture our products, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing our products depends on the extent to which we have rights under valid and enforceable patents (and/or trade secrets) that cover these activities. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will withstand subsequent challenges to their validity and or patentability, or if they will be commercially useful in protecting our product candidates, discovery programs and processes. Furthermore, we cannot be sure that our existing patents and patent applications will embrace (or “claim”) the particular uses for RP-G28 that will be approved by FDA.

The patent positions of biotechnology and pharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved.

No consistent policy regarding the patentability and/or validity of patent claims related to pharmaceutical patents has emerged, to date, in the United States or in most jurisdictions outside of the United States. Changes in either the patent laws (be they substantive or procedural) or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that will issue or will be enforceable in the patents that have or may be issued from the patents and applications we currently own or may in the future own or license from third parties. Further, if any patents we obtain, or to which we obtain licenses, are deemed invalid, unpatentable and unenforceable, our ability to commercialize or license our technology could be adversely affected.

In the future others may file patent applications covering products, uses for products, and manufacturing techniques and related technologies that are similar, identical or competitive to ours or important to our business. We cannot be certain that any patent application owned by a third party will not have priority over patent applications filed or in-licensed by us in the future, or that we or our licensors will not be involved in interference, opposition, inter partes review or invalidity proceedings before U.S. or non-U.S. patent offices or courts.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

Patents covering methods of using RP-G28 expire in 2030 if the appropriate maintenance fee renewal, annuity, or other government fees are paid, unless a patent term extension based on regulatory delay is obtained. We expect that expiration in 2030 of some of our method-of-use patents covering use of RP-G28 for treating lactose intolerance will have a limited impact on our ability to protect our intellectual property in the United States, where we have additional issued patents covering this use that extend until 2030. In other countries, our pending patent applications covering use of RP-G28 for treating other indications, if issued, would expire in 2030. We will attempt to mitigate the effect of patent expiration by seeking data exclusivity, or the foreign equivalent thereof, in conjunction with product approval, as well as by filing additional patent applications covering improvements in our intellectual property.

We expect that the other patent applications for the RP-G28 portfolio, if issued, and if the appropriate maintenance, renewal, annuity or other governmental fees are paid, would expire in 2030. We own pending applications in the United States and Europe covering RP-G28 analogs, and uses of such analogs as therapeutics to treat a variety of disorders, including lactose intolerance. Patent protection, to the extent it issues, would be expected to extend to 2030, unless a patent term extension based on regulatory delay is obtained.

Due to the patent laws of a country, or the decisions of a patent examiner in a country, or our own filing strategies, we may not obtain patent coverage for all of our product candidates or methods involving these candidates in the parent patent application. We plan to pursue divisional patent applications or continuation patent applications in the United States and other countries to obtain claim coverage for inventions which were disclosed but not claimed in the parent patent application.

We may also rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or feasible. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how.

RP-G28 does not have composition of matter patent protection.

Although we own certain patents and patent applications with claims directed to specific methods of using RP-G28 to treat lactose intolerance, RP-G28 has no composition of matter patent protection in the United States or elsewhere. As a result, we may be limited in our ability to list our patents in the FDA’s Orange Book if the use of our product, consistent with its FDA-approved label, would not fall within the scope of our patent claims. Also, our competitors may be able to offer and sell products so long as these competitors do not infringe any other patents that we (or third parties) hold, including patents with claims directed to the manufacture of RP-G28 and/or method of use patents. In general, method of use patents are more difficult to enforce than composition of matter patents because, for example, of the risks that FDA may approve alternative uses of the subject compounds not covered by the method of use patents, and others may engage in off-label sale or use of the subject compounds. Physicians are permitted to prescribe an approved product for uses that are not described in the product’s labeling. Although off-label prescriptions may infringe our method of use patents, the practice is common across medical specialties and such infringement is difficult to prevent or prosecute. FDA approval of uses that are not covered by our patents would limit our ability to generate revenue from the sale of RP-G28, if approved for commercial sale. Off-label sales would limit our ability to generate revenue from the sale of RP-G28, if approved for commercial sale.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights.

If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or company may seek a post grant review (including inter parte review) of our patents, and has the right to ask the court to rule that such patents are invalid or should not be enforced against that third party. These lawsuits and administrative proceedings are expensive and would consume time and resources and divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents. In addition, there is a risk that the court or administrative body will decide that such patents are not valid or unpatentable and that we do not have the right to stop the other party from using the inventions. There is also the risk that, even if the validity/patentability of such patents is upheld, the court will refuse to stop the other party on the ground that such other party’s activities do not infringe our rights to such patents. In addition, the U.S. Supreme Court and the Court of Appeals for the Federal Circuit have recently articulated and/or modified certain tests used by the U.S. Patent and Trademark Office (the “USPTO”), in assessing patentability and by the courts in assessing validity and claim scope, which may decrease the likelihood that we will be able to obtain patents and increase the likelihood that others may succeed in challenging any patents we obtain or license.

We may infringe the intellectual property rights of others, which may prevent or delay our product development efforts and stop us from commercializing or increase the costs of commercializing our product candidates.

Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. We cannot guarantee that our products, our methods of manufacture, or our uses of RP-G28 (or our other product candidates), will not infringe third-party patents. Furthermore, a third party may claim that we or our manufacturing or commercialization collaborators are using inventions covered by the third party’s patent rights and may go to court to stop us from engaging in our normal operations and activities, including making or selling our product candidates. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and scientific personnel. There is a risk that a court would decide that we or our commercialization collaborators are infringing the third party’s patents and would order us or our collaborators to stop the activities covered by the patents. In that event, we or our commercialization collaborators may not have a viable way around the patent and may need to halt commercialization of the relevant product. In addition, there is a risk that a court will order us or our collaborators to pay the other party damages for having violated the other party’s patents. In the future, we may agree to indemnify our commercial collaborators against certain intellectual property infringement claims brought by third parties. The pharmaceutical and biotechnology industries have produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The scope of coverage of a patent is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, the patentee would need to demonstrate, by a preponderance of the evidence that our products or methods infringe the patent claims of the relevant patent, and we would need to demonstrate either that we do not infringe or, by clear and convincing evidence, that the patent claims are invalid; we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these proceedings, we may incur substantial costs and divert management’s time and attention in pursuing these proceedings, which could have a material adverse effect on us. If we are unable to avoid infringing the patent rights of others, we may be required to seek a license, which may not be available, defend an infringement action or challenge the validity of the patents in court. Patent litigation is costly and time consuming. We may not have sufficient resources to bring these actions to a successful conclusion. In addition, if we do not obtain a license, develop or obtain non-infringing technology, fail to defend an infringement action successfully or have infringed patents declared invalid, we may incur substantial monetary damages, encounter significant delays in bringing our product candidates to market and be precluded from manufacturing or selling our product candidates.

We cannot be certain that others have not filed patent applications for technology covered by our pending applications, or that we were the first to invent the technology, because:

Our competitors may have filed, and may in the future file, patent applications covering technology similar to ours. Any such patent application may have priority over our patent applications, which could further require us to obtain rights to issued patents covering such technologies. If another party has filed a U.S. patent application on inventions similar to ours, we may have to participate in an interference proceeding declared by the USPTO to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if, unbeknownst to us, the other party had independently arrived at the same or similar invention prior to our own invention, resulting in a loss of our U.S. patent position with respect to such inventions. Other countries have similar laws that permit secrecy of patent applications, and may be entitled to priority over our applications in such jurisdictions.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We employ an outside firm and rely on our outside counsel to pay these fees due to non-U.S. patent agencies and this outside firm has systems in place to ensure compliance on payment of fees. The USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to enter the market and this circumstance would have a material adverse effect on our business.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. If we are not able to adequately prevent disclosure of trade secrets and other proprietary information, the value of our technology and products could be significantly diminished.

As is common in the biotechnology and pharmaceutical industries, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

We rely on trade secrets to protect our proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. For example, the FDA, as part of its Transparency Initiative, is currently considering whether to make additional information publicly available on a routine basis, including information that we may consider to be trade secrets or other proprietary information, and it is not clear at the present time how the FDA’s disclosure policies may change in the future, if at all. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

Failure to secure trademark registrations could adversely affect our business.

We have not developed a trademark for our RP-G28 product. Hence, we do not currently own any actual or potential trademark rights associated with our RP-G28 product. If we seek to register additional trademarks, including trademarks associated with our RP-G28 product, our trademark applications may not be allowed for registration or our registered trademarks may not be maintained or enforced. During trademark registration proceedings, we may receive rejections. Although we are given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in comparable agencies in many other jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we do not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties than we otherwise would.

Risks Relating to Our Common Stock

An active trading market for our common stock may not develop or be sustained.

Prior to our initial public offering, there was no public market for our common stock. Since our initial public offering in June 2015, there has been, and we expect that there will continue to be, only a limited volume of trading in our common stock. An active trading market in our common stock may not develop or, if developed, may not be sustained. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. The lack of an active market may also reduce the fair market value of your shares. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

Our share price may be volatile, which could subject us to securities class action litigation and prevent you from being able to sell your shares at or above your purchase price.

The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed in this section, and others beyond our control, including:

Furthermore, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of shares of our common stock. In addition, such fluctuations could subject us to securities class action litigation, which could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

Our executive officers, directors and principal stockholders maintain the ability to exert substantial influence over all matters submitted to stockholders for approval.

Our executive officers, directors and principal stockholders beneficially own shares representing approximately 28.6% of our outstanding capital stock. As a result, if these stockholders were to choose to act together, they would be able to exert substantial influence over all matters submitted to our stockholders for approval, as well as our management and affairs. For example, these persons, if they choose to act together, would exert substantial influence over the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of voting power could delay or prevent an acquisition of our Company on terms that other stockholders may desire.

We are an “emerging growth company” and avail ourselves of reduced disclosure requirements applicable to emerging growth companies, which could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We may take advantage of these reporting exemptions until we are no longer an “emerging growth company.” We will remain an emerging growth company until the earlier of  (i) the last day of the fiscal year (a) following the fifth anniversary of the date we completed our initial public offering, which was June 29, 2015, (b) in which we have total annual gross revenue of at least $1.0 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeded $700.0 million as of the prior June 30^th, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

Future sales of our common stock, or the perception that future sales may occur, may cause the market price of our common stock to decline, even if our business is doing well.

Sales by our stockholders of a substantial number of shares of our common stock in the public market could occur in the future. These sales, or the perception in the market that the holders of a large number of shares of common stock intend to sell shares, could reduce the market price of our common stock. We had 11,619,197 outstanding shares of common stock as of December 31, 2016. Of the shares outstanding, a total of 8,144,018 shares may be resold in the public market at any time and the remaining 3,475,179 shares are currently restricted under securities laws.

In connection with the Aspire Capital financing transaction, we registered and issued 1,577,699 shares of our common stock to Aspire Capital under the Aspire Purchase Agreement. We have registered an additional 3,000,000 shares of common stock that we may issue to Aspire Capital in the future under the terms of the Aspire Purchase Agreement. The number of shares ultimately offered for sale by Aspire Capital is dependent upon the number of shares we elect to sell to Aspire Capital under the Aspire Purchase Agreement. Aspire Capital may sell all, some or none of our shares that it holds or comes to hold under the Aspire Purchase Agreement. The sale of a substantial number of shares of our common stock by Aspire Capital, or anticipation of such sales, could cause the trading price of our common stock to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire. However, we have the right under the Aspire Purchase Agreement to control the timing and amount of sales of our shares to Aspire Capital, and the Aspire Purchase Agreement may be terminated by us at any time at our discretion without any penalty or cost to us.

We have also registered 2,565,284 shares of common stock that have been or may be issued under our equity compensation plans. These shares may be sold in the public market subject to any vesting conditions.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline.

The trading market for our common stock will depend on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. There can be no assurance that analysts will cover us or provide favorable coverage. If one or more of the analysts who cover us downgrade our stock or change their opinion of our stock, our share price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Our failure to meet the continued listing requirements of NASDAQ could result in a de-listing of our common stock.

If we fail to satisfy the continued listing requirements of NASDAQ, such as the corporate governance requirements or the minimum closing bid price requirement, NASDAQ may take steps to de-list our common stock. Such a de-listing would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a de-listing, we would take actions to restore our compliance with NASDAQ’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the NASDAQ minimum bid price requirement or prevent future non-compliance with NASDAQ’s listing requirements.

Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions provide that:

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful stockholder claims against us and may reduce the amount of money available to us.

As permitted by Section 102(b)(7) of the DGCL, our amended and restated certificate of incorporation limits the liability of our directors to the fullest extent permitted by law. In addition, as permitted by Section 145 of the DGCL, our amended and restated certificate of incorporation and our amended and restated bylaws provide that we shall indemnify, to the fullest extent authorized by the DGCL, each person who is involved in any litigation or other proceeding because such person is or was a director or officer of our company or is or was serving as an officer or director of another entity at our request, against all expense, loss or liability reasonably incurred or suffered in connection therewith. Our amended and restated certificate of incorporation provides that the right to indemnification includes the right to be paid expenses incurred in defending any proceeding in advance of its final disposition, provided, however, that such advance payment will only be made upon delivery to us of an undertaking, by or on behalf of the director or officer, to repay all amounts so advanced if it is ultimately determined that such director is not entitled to indemnification. If we do not pay a proper claim for indemnification in full within 60 days after we receive a written claim for such indemnification, except in the case of a claim for an advancement of expenses, in which case such period is 20 days, our restated certificate of incorporation and our restated bylaws authorize the claimant to bring an action against us and prescribe what constitutes a defense to such action.

Section 145 of the DGCL permits a corporation to indemnify any director or officer of the corporation against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with any action, suit or proceeding brought by reason of the fact that such person is or was a director or officer of the corporation, if such person acted in good faith and in a manner that he reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, if he or she had no reason to believe his or her conduct was unlawful. In a derivative action, (i.e., one brought by or on behalf of the corporation), indemnification may be provided only for expenses actually and reasonably incurred by any director or officer in connection with the defense or settlement of such an action or suit if such person acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification shall be provided if such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine that the defendant is fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.

The rights conferred in the restated certificate of incorporation and the restated bylaws are not exclusive, and we are authorized to enter into indemnification agreements with our directors, officers, employees and agents and to obtain insurance to indemnify such persons. We have entered into indemnification agreements with each of our officers and directors.

The above limitations on liability and our indemnification obligations limit the personal liability of our directors and officers for monetary damages for breach of their fiduciary duty as directors by shifting the burden of such losses and expenses to us. Although we plan to increase the coverage under our directors’ and officers’ liability insurance, certain liabilities or expenses covered by our indemnification obligations may not be covered by such insurance or the coverage limitation amounts may be exceeded. As a result, we may need to use a significant amount of our funds to satisfy our indemnification obligations, which could severely harm our business and financial condition and limit the funds available to stockholders who may choose to bring a claim against our company.

We have never paid dividends on our common stock and do not anticipate paying dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.

We have never paid dividends on our common stock and we do not anticipate paying dividends on our common stock for the foreseeable future. Accordingly, any return on an investment in our common stock will be realized, if at all, only when stockholders sell their shares. In addition, our failure to pay dividends may make our stock less attractive to investors, adversely impacting trading volume and price.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2016, we had federal net operating loss carryforwards, or NOLs, of approximately $26.7 million which begin to expire in 2028. Our ability to utilize our NOLs may be limited under Section 382 and 383 of the Internal Revenue Code. The limitations apply if an ownership change, as defined by Section 382, occurs. Generally, an ownership change occurs when certain shareholders increase their aggregate ownership by more than 50 percentage points over their lowest ownership percentage in a testing period (typically three years). Although we have not undergone a Section 382 analysis, it is possible that the utilization of the NOLs, could be substantially limited. Additionally, U.S. tax laws limit the time during which these carryforwards may be utilized against future taxes. As a result, we may not be able to take full advantage of these carryforwards for federal and state tax purposes. Future changes in stock ownership may also trigger an ownership change and, consequently, a Section 382 limitation.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

On July 9, 2015, we entered into a lease with Century Park, pursuant to which we lease approximately 2,780 square feet of office space in Los Angeles, California for our headquarters. The lease provides for a term of sixty-one (61) months, which commenced October 1, 2015. We paid no rent for the first month of the term and will pay base rent of $9,174 per month for months two through 13 of the term, with increasing base rent for each twelve-month period thereafter under the term of the lease to a maximum of $10,325 per month for months 50 through 61. We have the option to extend the term of the lease for one five-year term, provided that the rent would be subject to market adjustment at the beginning of the renewal term. We believe that our facility is suitable and adequate for our current needs.

Item 3. Legal Proceedings

From time to time, we have been and may again become involved in legal proceedings arising in the ordinary course of our business. We are not presently a party to any material litigation.

Item 4. Mine Safety Disclosures

Not Applicable.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our shares of common stock have been listed and traded on The NASDAQ Capital Market under the symbol “RTTR” since June 24, 2015. Prior to that date, there was no public market for our common stock.

The following table sets forth, for the periods indicated, the high and low intra-day sale prices in dollars on The NASDAQ Capital Market for our common stock.

Holders

As of February 20, 2017 there were approximately 42 registered holders of record of our common stock. These figures do not reflect the beneficial ownership or shares held in nominee name.

Dividend Policy

We have never paid or declared any cash dividends on our common stock, and we do not anticipate paying any cash dividends on our common stock in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. Any future determination to pay dividends will be at the discretion of our board of directors and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors our board of directors deems relevant. See “Risk Factors — Risks Relating to Our Common Stock— We have never paid dividends on our common stock and do not anticipate paying dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.”

Recent Sales of Unregistered Securities

On December 18, 2015, we entered into a common stock purchase agreement (the “Aspire Purchase Agreement”) with Aspire Capital Fund, LLC (“Aspire Capital”), which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $10.0 million of shares of our common stock over a 30-month period. Upon execution of the Aspire Purchase Agreement, we sold 500,000 shares of common stock (the “Initial Purchase Shares”) at $2.00 per share to Aspire Capital for proceeds of $1,000,000. In consideration for entering into the Aspire Purchase Agreement, we also issued to Aspire Capital 188,864 shares of our common stock (the “Commitment Shares”) concurrently with the execution of the Aspire Purchase Agreement. As of the date of this Annual Report, we have issued an aggregate of 1,577,699 shares to Aspire Capital for gross proceeds of $3.0 million. The issuance of the Initial Purchase Shares and the Commitment Shares were exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the exemption for transactions by an issuer not involving any public offering under Section 4(a)(2) of the Securities Act.

Use of Proceeds from Initial Public Offering of Common Stock

On June 24, 2015, our registration statement on Form S-1 (File No. 333-202924) relating to our initial public offering of our common stock was declared effective by the Securities and Exchange Commission (the “SEC”). Our initial public offering closed on June 29, 2015, and 4,000,000 shares of our common stock were sold at an initial public offering price of $5.00 per share, for aggregate gross proceeds to us of $20 million and net proceeds to us, after deducting underwriting discounts and commissions and offering expenses, of approximately $17.4 million.

Proceeds from the initial public offering have been used to fund our Phase 2b/3 trials and product development, including a $0.8 million payment to exercise an option with a research and development supplies. A portion of the proceeds ($227,250) was used to pay the annual bonuses earned by Andrew and Ira Ritter for 2015, based upon the achievement of specific performance goals, pursuant to the terms of their respective offer letters. Remaining proceeds from the initial public offering were spent to support general corporate purposes, general and administrative expenses, capital expenditures, working capital and prosecution and maintenance of our intellectual property. Therefore, our net cash proceeds from our initial public offering were expended as of December 31, 2016.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read together with our financial statements and the related notes appearing elsewhere in this Annual Report. This discussion contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. See “Special Note Regarding Forward-Looking Statements and Industry Data” for a discussion of the uncertainties, risks and assumptions associated with these statements. Actual results and the timing of events could differ materially from those discussed in our forward-looking statements as a result of many factors, including those set forth under “Risk Factors” and elsewhere in this Annual Report.

Overview

Ritter Pharmaceuticals, Inc. develops novel therapeutic products that modulate the human gut microbiome to treat gastrointestinal diseases. We are advancing human gut health research by exploring the metabolic capacity of the gut microbiota and translating the functionality of prebiotic-based therapeutics into applications intended to have a meaningful impact on a patient’s health. We have completed a Phase 2a clinical trial of our leading product candidate, RP-G28, an orally administered, high purity oligosaccharide. We initiated a Phase 2b/3 clinical trial of RP-G28 in March 2016 with enrollment completed in August 2016. In October 2016, the last patient completed dosing and all monitoring visits in our Phase 2b/3 clinical trial of RP-G28 for the treatment of lactose intolerance. Topline results of the trial are expected to be announced in the first quarter of 2017.

We have devoted substantially all of our resources to development efforts relating to RP-G28, including conducting clinical trials of RP-G28, providing general and administrative support for these operations and protecting our intellectual property. We currently do not have any products approved for sale and we have not generated any revenue from product sales since our inception. Prior to our initial public offering, we funded our operations primarily through the private placement of preferred stock, common stock and promissory notes.

On June 24, 2015, our registration statement on Form S-1 (File No. 333-202924) relating to our initial public offering of common stock was declared effective by the SEC. The shares began trading on the NASDAQ Capital Market on June 24, 2015. The initial public offering closed on June 29, 2015, and 4,000,000 shares of common stock were sold at an initial public offering price of $5.00 per share, for aggregate gross proceeds to us of $20 million. After deducting underwriting discounts and commissions and other offering expenses payable by us, net proceeds were approximately $17.4 million.

On October 31, 2016, we closed a public offering of 2,127,660 shares of our common stock at a price to the public of $2.35 per share, for net proceeds of approximately $4.4 million, after deducting underwriting discounts and commissions and offering expenses payable by us in the offering.

We have incurred net losses in each year since our inception, including a net loss of approximately $18.4 million for the year ended December 31, 2016. We had an accumulated deficit of approximately $45.5 million as of December 31, 2016. Substantially all our net losses resulted from costs incurred in connection with our research and development programs, stock-based compensation, and from general and administrative costs associated with our operations.

We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. We anticipate that our expenses will increase substantially as we:

We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for RP-G28, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital in addition to the net proceeds received in our initial public offering and follow-on offering, and any proceeds received from our sale of shares of common stock to Aspire Capital pursuant to the Aspire Purchase Agreement, prior to the commercialization of RP-G28. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our operating activities through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to develop our product candidates.

Financial Overview

Revenue

We have not generated any revenue since our inception. Our ability to generate revenue in the future will depend almost entirely on our ability to successfully develop, obtain regulatory approval for and then successfully commercialize RP-G28 in the United States. In the event we choose to pursue a partnering arrangement to commercialize RP-G28 or other products outside the United States, we would expect to initiate additional research and development and clinical trial activities in the future.

Research and Development Expenses

Since our inception, we have focused our resources on our research and development activities, including conducting nonclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for RP-G28. Our research and development expenses consist primarily of:

From inception through December 31, 2016, we have incurred approximately $19.2 million in research and development expenses. We plan to increase our research and development expenses for the foreseeable future as we continue the development of RP-G28 for the reduction of symptoms associated with lactose intolerance in patients and other indications, subject to the availability of additional funding.

The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs of the efforts that will be necessary to complete the development of RP-G28 or the period, if any, in which material net cash inflows from RP-G28 may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

A change in the outcome of any of these variables with respect to the development of RP-G28 could mean a significant change in the costs and timing associated with its development. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of RP-G28 or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

RP-G28

Our research and development resources are focused on completing our Phase 2b/3 clinical trial and any other clinical and nonclinical studies and other work needed to submit RP-G28 for the reduction of symptoms associated with lactose intolerance in patients for regulatory approval in the United States and Europe. We have incurred and expect to continue to incur expenses in connection with these efforts.

Patent Costs

Patent costs consist primarily of professional fees for legal services to prosecute patents and maintain patent rights.

General and Administrative Expenses

General and administrative expenses include allocation of facilities costs, salaries, benefits, and stock-based compensation for employees, professional fees for directors, fees for independent contractors and accounting and legal services.

We expect that our general and administrative expenses will increase as we continue to operate as a public company and will increase further if RP-G28 is approved for commercialization. We believe that these increases will likely include increased costs for director and officer liability insurance, and increased fees for outside consultants, lawyers and accountants, among other expenses.

Interest Income

Interest income consists of interest earned on our cash.

Critical Accounting Estimates

This discussion and analysis is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to fair value of financial instruments, research and development costs, accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events and various other factors we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 3 to our financial statements appearing in “Item 8. Financial Statements and Supplementary Data,” we believe that the following accounting policies are the most critical to aid you in fully understanding and evaluating our financial condition and results of operations.

Fair Value of Financial Instruments

Fair value measurement guidelines are prescribed by GAAP to value financial instruments. The guidance includes a definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements.

The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

These two types of inputs create the following fair value hierarchy:

Level 1 — Quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 primarily consists of financial instruments whose value is based on quoted market prices such as exchange-traded instruments and listed equities.

Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models consider various assumptions, including volatility factors, current market prices and contractual prices for the underlying financial instruments. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 — Unobservable inputs for the asset or liability. Financial instruments are considered Level 3 when their fair values are determined using pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

The carrying amounts reported in the balance sheet for cash and cash equivalents, prepaid expenses, accounts payable, accrued expenses, and the notes payable approximate the fair values due to the short-term nature of the instruments.

Research and Development Costs

We expense the cost of research and development as incurred. Research and development expenses comprise costs incurred in performing research and development activities, including clinical study costs, contracted services, and other external costs. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity is performed or when the goods have been received, rather than when payment is made, in accordance with ASC 730, Research and Development.

Accrued Expenses

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses include fees due to service providers.

We base our expenses on our estimates of the services received and efforts expended pursuant to quotes and contracts with our service providers that conduct research and development on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period.

Stock-Based Compensation

Stock-based compensation cost for equity awards granted to employees and nonemployees is measured at the grant date based on the calculated fair value of the award using the Black-Scholes option-pricing model, and is recognized as an expense, under the straight-line method, over the requisite service period (generally the vesting period of the equity grant). If we determine that other methods are more reasonable, or other methods for calculating these assumptions are prescribed by regulators, the fair value calculated for our stock options could change significantly. Higher volatility and longer expected lives would result in an increase to stock-based compensation expense to non-employees determined at the date of grant.

In addition to the assumptions used in the Black-Scholes option-pricing model, we also estimate a forfeiture rate to calculate the stock-based compensation for our equity awards. We will continue to use judgment in evaluating the expected volatility, expected terms and forfeiture rates utilized for our stock-based compensation calculations on a prospective basis.

Emerging Growth Company Status

On April 5, 2012, the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the Securities Act), for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period for complying with new or revised accounting standards under Section 102(b)(1) of the JOBS Act. This election allows us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, as an “emerging growth company,” we intend to rely on certain of these exemptions, including without limitation, (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year (a) following the fifth anniversary of the date we completed our initial public offering, which was June 29, 2015, (b) in which we have total annual gross revenue of at least $1.0 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeded $700.0 million as of the prior June 30th, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

Results of Operations

Comparison of the years ended December 31, 2016 and 2015

The following table summarizes the results of our operations for the years ended December 31, 2016 and 2015, together with the changes in those items in dollars and as a percentage:

Research and Development Expenses

Research and development expenses increased by approximately $11.0 million, or 488%, for the year ended December 31, 2016 as compared to the year ended December 31, 2015. The majority of the increase was due to costs incurred in connection with our Phase 2b/3 clinical trial that was initiated in March 2016. An increase of approximately $11.1 million was attributable to fees paid to our third-party CRO as part of our Phase 2b/3 clinical trial, offset by approximately $0.3 lower manufacturing costs and approximately $0.5 lower pre-trial research fees. The remaining $0.6 million increase was the result of higher consulting fees and new costs incurred for the onset of a 12-month extension study to evaluate the long-term durability of treatment. There was no clinical trial during the 2015 year.

Patent Costs

Patent costs were approximately $273,000 and $243,000 for the years ended December 31, 2016 and 2015, respectively, representing an increase of approximately $29,000, or 12%. The increase was primarily due to overall timing of certain costs related to our maintenance of patent rights, our prosecution of patents for an increased number of patents and our application for the issuance of patents as well as our preparation to file national phase applications in certain foreign countries. During 2016, three patents were issued - U.S. Patent Nos. 9,200,303, 9,226,933 and 9,370,532.

General and Administrative Expenses

General and administrative expenses decreased by approximately $1.5 million, or 24%, for the year ended December 31, 2016 as compared to the year ended December 31, 2015. The decrease in general and administrative expenses was mainly due to a decrease in stock-based compensation expense of approximately $1.5 million. The increase in cost of being a public company for the full year 2016 was offset by lower expenses as a result of cost containment practices.

Other Income

Interest income increased by approximately $20,000, or 49%, during the year ended December 31, 2016 as compared to the year ended December 31, 2015, due to the longer period interest earned on cash balances from the net proceeds of our initial public offering. Other income decreased by approximately $79,000, or 98%, during year ended December 31, 2016 as compared to the same 2015 period, as gains on the settlement of accounts payable during the year ended December 31, 2015 were not realized during the same 2016 period.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have incurred net losses and negative cash flows from operations, and, as of December 31, 2016, we had an accumulated deficit of approximately $45.5 million. Substantially all our net losses resulted from costs incurred in connection with our research and development programs, stock-based compensation, and from general and administrative costs associated with our operations.

At December 31, 2016, we had working capital of $4.1 million, and cash of $7.0 million. We have not generated any product revenues and have not achieved profitable operations.

Aspire Capital Financing Arrangement

On December 18, 2015, we entered into the Aspire Purchase Agreement with Aspire Capital, which provides that, upon the terms and subject to the conditions and limitations set forth therein, Aspire Capital is committed to purchase up to an aggregate of $10.0 million of our shares of common stock over the approximately 30-month term of the Aspire Purchase Agreement. In consideration for entering into the Purchase Agreement, concurrently with the execution of the Purchase Agreement, we issued to Aspire Capital 188,864 shares of our common stock as a commitment fee, or the Commitment Shares. Upon execution of the Aspire Purchase Agreement, we sold 500,000 shares of common stock to Aspire Capital at $2.00 per share for proceeds of $1.0 million. On December 8, 2016, we sold the remaining 888,835 shares of common stock available pursuant to the terms of the Aspire Purchase Agreement to Aspire Capital at $2.28 per share for proceeds of $2.0 million. As of December 31, 2016, we have issued an aggregate of 1,577,699 shares of our common stock to Aspire Capital under the Purchase Agreement for aggregate proceeds of approximately $3.0 million.

On any trading day on which the closing sale price of our common stock exceeds $0.50, we have the right, in our sole discretion, to present Aspire Capital with a purchase notice (each a “Purchase Notice”), directing Aspire Capital (as principal) to purchase up to 100,000 shares of our common stock per trading day, for up to $7.0 million of our common stock in the aggregate at a per share price (the “Purchase Price”), calculated by reference to the prevailing market price of our common stock (as provided in the Aspire Purchase Agreement).

In addition, any date on which we submit a Purchase Notice for 100,000 shares to Aspire Capital and the closing sale price of our stock is equal to or greater than $0.50 per share of common stock, we also have the right, in our sole discretion, to present Aspire Capital with a volume-weighted average price purchase notice (each a “VWAP Purchase Notice”), directing Aspire Capital to purchase an amount of stock equal to up to 30% of the aggregate shares of our common stock traded on the Nasdaq Capital Market on the next trading day (the “VWAP Purchase Date”), subject to a maximum number of shares we may determine (the “VWAP Purchase Share Volume Maximum”), and a minimum trading price (the “VWAP Minimum Price Threshold”) (as more specifically described below). The purchase price per share pursuant to such VWAP Purchase Notice (the “VWAP Purchase Price”) is calculated by reference to the prevailing market price of our common stock (as provided in the Aspire Purchase Agreement).

The Aspire Purchase Agreement provides that we and Aspire Capital will not effect any sales under the Aspire Purchase Agreement on any purchase date where the closing sale price of our common stock is less than $0.50 per share (the “Floor Price”). This Floor Price and the respective prices and share numbers in the preceding paragraphs will be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction. There are no trading volume requirements or restrictions under the Aspire Purchase Agreement, and we will control the timing and amount of any sales of our common stock to Aspire Capital. Aspire Capital has no right to require any sales by us, but is obligated to make purchases from us as we direct in accordance with the Purchase Agreement. There are no limitations on use of proceeds, financial or business covenants, restrictions on future fundings, rights of first refusal, participation rights, penalties or liquidated damages in the Aspire Purchase Agreement. Aspire Capital may not assign its rights or obligations under the Purchase Agreement. The Purchase Agreement may be terminated by us at any time, at our discretion, without any penalty or cost to us.

We expect to use the Aspire facility to complement, rather than replace, other financing that may be required during the next twelve months to continue our operations and support our capital needs.

October 2016 Public Offering

On October 31, 2016, we closed a public offering of 2,127,660 shares of our common stock at a price to the public of $2.35 per share, for net proceeds of approximately $4.4 million, after deducting underwriting discounts and commissions and offering expenses payable by us in the offering. The offering was made pursuant to a shelf registration statement on Form S-3 (Registration Number 333-213087).

Cash Flows

The following table sets forth the significant sources and uses of cash for the periods set forth below:

Operating Activities

The use of cash in all periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital. Net cash used in operating activities was approximately $15.2 million during the year ended December 31, 2016 compared to $5.7 million during the year ended December 31, 2015. The increase in cash used in operating activities was driven by the initiation of our Phase 2b/3 clinical trial in March 2016. Patient enrollment was completed in August 2016 and the last patient was dosed in October 2016. A total of 377 patients enrolled at 18 clinical sites throughout the United States. There was no clinical trial during 2015.

Investing Activities

Net cash used in investing activities of was approximately $8,000 during the year ended December 31, 2016 compared to approximately $17,000 for the year ended December 31, 2015 due to the reduction in purchases of property and equipment.

Financing Activities

Net cash provided by financing activities was approximately $6.4 million during the year ended December 31, 2016 compared to $18.8 million during the year ended December 31, 2015. As described below, during the 2015 year, we received proceeds from our initial public offering whereas we did not have the same level of financing activities during the 2016, resulting in the decrease.

Net cash provided by financing activities of approximately $6.4 million during the year ended December 31, 2016 was due to net proceeds from the October 2016 follow-on offering of approximately $4.4 million and issuance of shares to Aspire Capital under the Aspire Purchase Agreement of approximately $2.0 million. Net cash provided by financing activities of approximately $18.8 million during the year ended December 31, 2015 was attributable to the net proceeds of approximately $17.4 million received upon closing of our initial public offering, selling 4,000,000 shares of our common stock. Additionally, proceeds of $1.0 million were received in connection with the sale of shares of our common stock to Aspire Capital pursuant to the Aspire Purchase Agreement.

Future Funding Requirements

To date, we have not generated any revenue. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate significant revenue from product sales unless and until we obtain regulatory approval of and commercialize RP-G28 or any of our other product candidates. At the same time, we expect our expenses to increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. Additionally, we have incurred and will continue to incur additional costs associated with operating as a public company. In addition, subject to obtaining regulatory approval of any of our product candidates, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations.

Based upon our current operating plan, we believe that our existing cash and cash equivalents, together with interest and any proceeds received from our sale of shares of common stock to Aspire Capital in the future pursuant to the Aspire Purchase Agreement, will enable us to fund our operating expenses and capital expenditure requirements through 2017. We intend to devote our existing financial resources to fund the continued clinical development of RP-G28, including completion of our Phase 2b/3 trial and extension study; to fund expenses associated with the manufacture and product development of RP-G28; to explore potential orphan indications; and for general corporate purposes, general and administrative expenses, capital expenditures, working capital and prosecution and maintenance of our intellectual property.

Our future capital requirements will depend on many factors, including:

Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our cash needs through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our common stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through government or other third-party funding, commercialization, marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements as defined under SEC rules.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2016-02, Leases (Topic 842) (“ASU 2016-02”). The provisions of ASU 2016-02 set out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for under the existing guidance for operating leases today. Topic 842 supersedes the previous lease standard, Topic 840 Leases. The guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018, and is effective for the Company for the year ending December 31, 2019. The Company is currently evaluating the impact that the implementation of this standard will have on the Company’s financial statements.

On March 30, 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). Among other things, ASU 2016-09 requires that entities recognize excess tax benefits and deficiencies related to employee share-based payment transactions as income tax expense or benefit. ASU 2016-09 also eliminates the requirement to reclassify excess tax benefits and deficiencies from operating activities to financing activities in the statement of cash flows. The guidance is effective for the annual periods and interim periods within those annual periods beginning after December 15, 2016. The adoption of this standard did not have any impact on the Company’s financial statements.

On August 26, 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230), a consensus of the FASB’s Emerging Issues Task Force (“ASU 2016-15”). The new guidance amends Accounting Standards Codification No. 230 (“ASC 230”) to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASC 230 lacks consistent principles for evaluating the classification of cash payments and receipts in the statement of cash flows. This has led to diversity in practice and, in certain circumstances, financial statement restatements. Therefore, the FASB issued the ASU 2016-15 with the intent of reducing diversity in practice with respect to eight types of cash flows. ASU 2016-15 is effective for annual and interim periods in fiscal years beginning after December 15, 2017, and is effective for the Company for the year ending December 31, 2018. The Company is currently evaluating the impact that the implementation of this standard will have on the Company’s financial statements.

Other accounting standards updates effective after December 31, 2016, are not expected to have a material effect on our financial position, annual results of operations and/or cash flows.

The financial statements and the reports of our independent registered accounting firm required pursuant to this item are included in Item 15 of this report and are presented beginning on page F-1.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

There has been no change of accountants nor any disagreements with accountants on any matter of accounting principles or practices or financial disclosure required to be reported under this Item.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer (our principal executive officer) and vice president finance (our principal financial officer), evaluated the effectiveness of our disclosures controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended (the “Exchange Act”), as of December 31, 2016. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2016, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at a reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

Internal control over financial reporting refers to the process designed by, or under the supervision of, our chief executive officer and vice president finance, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (2) provide a reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitation. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgement and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Management is responsible for establishing and maintaining adequate internal control over our financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our chief executive officer and vice president finance, we conducted an evaluation of the effectiveness of our internal control over financial reporting. Management has used the framework set forth in the report entitled “Internal Control – Integrated Framework” published by the Committee of Sponsoring Organizations of the Treadway Commission to evaluate the effectiveness of our internal control over financial reporting. Based on its evaluation, management has concluded that our internal control over financial reporting was effective as of December 31, 2016, the end of our most recent fiscal year.
