Forward-Looking Statements

This Quarterly Report on Form 10-Q (“Report”) (including but not limited to this Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”) contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are intended to qualify for the “safe harbor” created by those sections. In addition, we may make forward-looking statements in other documents filed with or furnished to the SEC, and our management and other representatives may make forward-looking statements orally or in writing to analysts, investors, representatives of the media and others. You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes to those statements included elsewhere in this Report. This discussion and analysis and other parts of this Report contain forward-looking statements based upon current beliefs, plans and expectations related to future events and our future financial performance that involve risks, uncertainties and assumptions, such as statements regarding our intentions, plans, objectives, expectations, forecasts and projections. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors.

All statements included or incorporated by reference in this Report, other than statements or characterizations of historical fact, are forward-looking statements. Forward-looking statements can generally be identified by the fact that they do not relate strictly to historical or current facts and include, but are not limited to, statements using terminology such as “can”, “may”, “could”, “should”, “assume”, “forecasts”, “believe”, “designed to”, “will”, “expect”, “plan”, “anticipate”, “estimate”, “potential”, “position”, “predicts”, “strategy”, “guidance”, “intend”, “seek”, “budget”, “project” or “continue”, or the negative thereof or other comparable terminology regarding beliefs, plans, expectations or intentions regarding the future. You should read statements that contain these words carefully because they:

We believe it is important to communicate our expectations. However, forward-looking statements are based on our current expectations, assumptions, estimates, approximations and projections about our business and our industry and management’s beliefs, all of which are subject to change. Forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties and other factors. Accordingly, our actual results and the timing of certain events may differ materially and adversely from those expressed or implied in such forward-looking statements due to a variety of factors and risks, including, but not limited to, those set forth in this Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in our unaudited condensed consolidated financial statements and notes thereto included in this Report, those set forth from time to time in our other filings with the SEC, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as amended, and the following factors and risks:

Any or all of our forward-looking statements may turn out to be wrong. They may be affected by inaccurate assumptions that we might make or by known or unknown risks and uncertainties. Actual outcomes and results may differ materially from what is expressed or implied in our forward-looking statements.

All forward-looking statements and risk factors included in this Report are made as of the date hereof, in each case based on information available to us as of the date hereof, and we assume no obligations to update any forward-looking statement or risk factor, unless we are required to do so by law. If we do update one or more forward-looking statements, no inference should be drawn that we will make updates with respect to other forward-looking statements or that we will make any further updates to those forward-looking statements at any future time.

Forward-looking statements may include our plans and objectives for future operations, including plans and objectives relating to our product candidates and our future economic performance, projections, business strategy and timing and likelihood of success. Assumptions relating to the forward-looking statements included in this Report involve judgments with respect to, among other things, future economic, competitive and market conditions, future business decisions, and the time and money required to successfully complete development and commercialization of our product candidates, all of which are difficult or impossible to predict accurately and many of which are beyond our control.

Any of the assumptions underlying the forward-looking statements contained in this Report could prove inaccurate and, therefore, we cannot assure you that any of the results or events contemplated in any of such forward-looking statements will be realized. Based on the significant uncertainties inherent in these forward-looking statements, the inclusion of any such statement should not be regarded as a representation or as a guarantee by us that our objectives or plans will be achieved, and we caution you against relying on any of the forward-looking statements contained herein.

Overview

We are a clinical-stage pharmaceutical company developing protein kinase inhibitor therapeutics to modify the course of Parkinson’s disease ("PD"), Parkinson’s-related disorders and other diseases of the Abelson Tyrosine Kinases. The Company’s multi-therapeutic pipeline has a primary focus on neurodegeneration and its lead program utilizing IkT-148009, a selective inhibitor of the non-receptor Abelson Tyrosine Kinases, targets the treatment of Parkinson’s disease inside and outside the brain as well as other diseases that arise from Abelson Tyrosine Kinases. In 2021, we commenced clinical development of IkT-148009, which we believe can modify the course of Parkinson’s disease including its manifestation in the gastrointestinal tract, or GI. The FDA review of the Phase 1/1b data and the protocol for the Phase 2a three-month dosing study resulted in the FDA agreeing with the Company’s view that it was appropriate for the Phase 2a study to begin, prompting the Company to initiate the Phase 2a study, the 201 trial, at the end of May 2022. In October 2022, an IND to expand use of IkT-148009 into the Parkinson’s-related disease Multiple System Atrophy, or MSA, was filed with the FDA. On November 7, 2022, following review of the IND for IkT-148009 as a treatment for MSA, the FDA notified the Company that it was placing the IkT-148009 programs for Parkinson’s disease and MSA on clinical hold. The FDA lifted the full clinical hold in January 2023 for the Parkinson’s programs and in March 2023 on the MSA program, opening the IND for MSA. 20 of 36 planned sites have completed site opening procedures and 7 sites are currently screening patients. It is anticipated that up to 14 sites may be screening patients by the end of May 2023. The 201 PD trial will enroll patients at 50 mg and 100 mg, with the 200 mg dose added back into the trial on a staggered schedule relative to the 50 mg, 100 mg and placebo cohorts. Safety and pharmacokinetic data from the analysis of the 200 mg dose in 6 older healthy adults was submitted to the FDA early in the second quarter of 2023. The FDA further requested the measurement of visual acuity and examination of the cornea and lens to complement the analysis of retina, macula and fundus that was already part of the ocular monitoring program in the 201 trial.

Our evaluation of IkT-148009 in MSA has been benefited by a grant received from the National Institute of Neurological Diseases and Stroke, an Institute of the National Institutes of Health, for $0.39 million to fund animal model studies of IkT-148009 as a therapy for MSA. Two animal studies are under way, with the transgenic model showing that once daily dosing of IkT-148009 for up to 20 weeks can preclude functional loss relative to untreated controls. We plan to initiate a Phase 2 study in MSA patients in up to nineteen sites in the EU, and up to six sites in the U.S. involving 60 patients if these animal model outcomes support pursuit of IkT-148009 in this indication. The proposed Phase 2 study will have primary endpoints in safety and tolerability and secondary endpoints

16

in MSA efficacy following once daily dosing at two dose levels for 6-months. The Company has submitted orphan drug designation for IkT-148009 to treat MSA in the U.S and plans to make a similar filing with regulators in Europe.

The Company is also developing platform technologies for alternate ways to deliver protein kinase inhibitors in patients. Our first example of this technology is IkT-001Pro, a prodrug of the anticancer agent imatinib mesylate, to treat Stable Phase Chronic Myelogenous Leukemia (SP-CML). Pursuant to its IND, which was cleared by the FDA in August 2022, IkT-001Pro is being evaluated in a two-part dose finding/dose equivalence study in up to 59 healthy volunteers (the 501 trial). The study is designed to evaluate the 96-hour pharmacokinetics of imatinib delivered as IkT-001Pro and determine the dose of IkT-001Pro that can deliver the equivalent 400 mg imatinib, the standard-of-care dose for SP-CML. As of the date of this Report, four of four dose escalation cohorts have completed the trial; it is anticipated that the dose finding/dose equivalence program will be completed by the end of the second quarter of 2023. Only four mild adverse events have been observed, none of clinical significance for IkT-001Pro. IkT-001Pro has high oral bioavailability and a pharmacokinetic profile of delivered imatinib that closely matches the exposure of imatinib delivered as 400 mg imatinib mesylate. Following the 501 study, Inhibikase will confer with the FDA and seek agreement on the requirements for the NDA process following the proposed approval path for IkT-001Pro under the 505(b)(2) approval pathway. The Company plans to simultaneously pursue a superiority study comparing the selected doses of IkT-001Pro to standard-of-care 400 mg imatinib in SP-CML patients using a novel, two-period-wait-list-crossover-switching study.

For both IkT-148009 and IkT-001Pro, we have completed clinical batch manufacturing of a film-coated tablet formulation. The bioequivalence studies with IkT-001Pro have already implemented these tablets into the study. A pharmacokinetic bridging study with two different tablet formulations of IkT-148009 is planned to be completed in 2023.

In our opinion, the multi-decade failures in the treatment of neurodegenerative diseases such as PD result from a lack of understanding of the biochemistry of the disease processes involved. Neurodegeneration is marked by a progressive degeneration and loss of function of neurons which send and receive signals to and from the brain. Historically, the cause of a neurodegenerative disease was thought to be a “plaque” made up of a misfolded and/or aggregated protein(s). Therapeutic approaches, therefore, sought to remove “plaque” from the brain. A “plaque”-focused treatment strategy has failed to alter the course of Parkinson’s disease in two Phase 2 trials that reported results in 2020 and 2021. We believe we are different. We identified the proteins that become dysfunctional in a disease pathway and sought to understand how a dysfunctional protein causes disease. We believe our approach to PD and other neurological diseases has identified the underlying cause of disease and led to an understanding of how individual proteins are linked together to define the disease process. Using this strategy, we believe we have discovered at least one enzyme that plays a pivotal role in the disease process for PD, the Abelson Tyrosine Kinase, or c-Abl. We have developed novel protein kinase inhibitors against c-Abl, which we believe can alter the disease course for PD. c-Abl chemically modifies the “plaque” proteins in PD, known as alpha-synuclein. Chemical modification creates what we believe to be the true toxic entity of the disease. Treatment with IkT-148009 may prevent chemical modification and, at least in animal models of progressive disease, leads to near clearance of the toxic form of alpha-synuclein from the affected neurons.

We believe we are one of the pioneers of the application of protein kinase inhibitors to non-oncology indications, including neurodegeneration and infectious diseases, as well as their more traditional role in the treatment of cancer. Prior to becoming a publicly-traded company in 2020, more than 50% of the Company’s total funding had been received from Private, State and Federal granting agencies, including the National Institutes of Health, the Department of Defense and the Michael J. Fox Foundation, with the balance the result of equity sales in the private sector. Private, State and Federal granting agencies use extensive scientific peer review in deciding which projects to fund that could impact human disease. Our ability to advance the Company on the basis of scientific peer review reflects the potential our scientific peers see for the possible success of our therapeutic programs.

Impact of the ongoing military conflict between Russia and Ukraine

In late February 2022, Russia invaded Ukraine, significantly amplifying already existing geopolitical tensions among Russia and other countries in the region and in the west, including the U.S. Russia’s invasion, the responses of countries and political bodies to Russia’s actions, the larger overarching tensions, and Ukraine’s military response and the potential for wider conflict have resulted in financial market volatility and capital markets disruption and inflation, potentially increasing in magnitude, and could have severe adverse effects on regional and global economic markets and international relations. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial.

17

Following Russia’s actions, various countries, including the U.S., Canada and the United Kingdom, as well as the European Union, issued broad-ranging economic sanctions against Russia. Such sanctions included, among other things, a prohibition on doing business with certain Russian companies, officials and oligarchs; a commitment by certain countries and the European Union to remove selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (SWIFT) electronic banking network that connects banks globally; a ban on Russian oil and gas imports to the U.S.; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current sanctions (and potential further sanctions in response to continued Russian military activity) and other actions may have adverse effects on regional and global economic markets and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for us to obtain additional funds and increasing the volatility of our stock price. Any of the above mentioned factors could affect our business, prospects, financial condition, and operating results.

We are also monitoring other macro-economic and geopolitical developments such as inflation and cybersecurity risks so that we can be prepared to react to new developments as they arise.
 

Components of Operating Results

Operating Expenses

Research and Development

Research and development activities account for a significant portion of our operating expenses. We record research and development expenses as incurred. Research and development expenses incurred by us for the discovery and development of our product candidates and prodrug technologies include:

A portion of our research and development expenses are direct external expenses, which we track on a program-specific basis from inception of the program.

Program expenses include expenses associated with our most advanced product candidates and the discovery and development of compounds that are potential future candidates. We also track external expenses associated with our third-party research and development efforts. All external costs are tracked by therapeutic indication. We do not track personnel or other operating expenses incurred for our research and development programs on a program-specific basis. These expenses primarily relate to salaries and benefits and stock-based compensation and office consumables.

At this time, we can only estimate the nature, timing and costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from sales or licensing of our product candidates. This is due to the numerous risks and uncertainties associated with drug development, including the uncertainty of:

18

A change in any of these variables with respect to the development of any of our product candidates would significantly change the costs, timing and viability associated with the development of that product candidate. We expect our research and development expenses to increase for the next several years as we continue to implement our business strategy, advance our current programs, expand our research and development efforts, seek regulatory approvals for any product candidates that successfully complete clinical trials, access and develop additional product candidates and incur expenses associated with hiring additional personnel to support our research and development efforts. In addition, product candidates in later stages of clinical development generally incur higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials.

Our direct research and development expenses consist principally of external costs, such as fees paid to investigators, consultants, central laboratories and CROs in connection with our clinical studies, and costs related to acquiring and manufacturing clinical study materials. We allocate salary and benefit costs directly related to specific programs. We do not allocate personnel-related discretionary bonus or stock-based compensation costs, laboratory and related expenses, depreciation or other indirect costs that are deployed across multiple projects under development and, as such, the costs are separately classified as other research and development expenses in the table below:
