OVERVIEW

Windtree Therapeutics, Inc. (referred to as “we,” “us,” or the “Company”) is a biotechnology and medical device company focused on developing drug product candidates and medical device technologies to address acute pulmonary and cardiovascular diseases. Historically, our focus has been on the development of our proprietary KL4 surfactant technology and aerosol delivery system (ADS) technology for the treatment and/or prevention of respiratory distress syndrome (RDS) in premature infants. On December 21, 2018, we entered into an Agreement and Plan of Merger (the CVie Acquisition) with CVie Investments Limited (CVie Investments), an exempted company with limited liability incorporated under the laws of the Cayman Islands, pursuant to which we issued shares of our common stock, par value $0.001 per share (common stock), to CVie Investments’ former shareholders, at an exchange ratio of 0.3512 share of common stock for each share of CVie Investments outstanding prior to the merger, resulting in the issuance of 16,265,060 shares of common stock in exchange for the outstanding shares of CVie Investments. Since the CVie Acquisition, we have operated CVie Investments, and its wholly-owned subsidiary, CVie Therapeutics Limited (CVie Therapeutics), a Taiwan corporation organized under the laws of the Republic of China, as a business division (these entities may be collectively referred to herein as CVie) focused on development of drug product candidates for cardiovascular diseases, including acute heart failure and hypertension and associated organ dysfunction.

Our four lead development programs are (1) istaroxime for treatment of acute decompensated heart failure (ADHF), (2) AEROSURF® (lucinactant for inhalation) for non-invasive delivery of our lyophilized KL4 surfactant to treat RDS in premature infants, (3) lyophilized KL4 surfactant intratracheal suspension for RDS, and (4) rostafuroxin for genetically associated hypertension.

Heart failure is a chronic, progressive disease resulting from structural or functional cardiac abnormalities and is characterized by inadequate pumping function of the heart that results in fluid accumulation manifesting as pulmonary congestion, peripheral edema and congestion in other parts of the body. Insufficient cardiac output can result in inadequate peripheral perfusion that increases the risk of other organ dysfunction such as renal failure. Heart failure commonly but episodically worsens to a point of decompensation, a condition called ADHF. Istaroxime is an investigational drug product, which has a dual mechanism of action referred to as luso-inotropic, that may result in improvement in cardiac function to reduce congestion and edema and preserve other organ function while avoiding the side effects associated with other classes of heart failure therapies.  Istaroxime has been evaluated in two phase 2 clinical trials, the results of which suggest that istaroxime may improve cardiovascular physiology as assessed by parameters of pump function, decreases in pulmonary capillary wedge pressure, decreases in heart rate, increases in blood pressure without adverse events such as arrhythmias, cardiac damage (as indicated by elevated troponin values) or adverse impact on kidney function. Based on preclinical and clinical studies performed to date, we believe that istaroxime, if approved, could potentially improve patients’ heart failure symptoms and reduce complications and the length of hospital stays when compared to current therapeutic regimens for ADHF. We have engaged with leading heart failure opinion leaders to assist us with plans for the program and have engaged with the FDA to gain alignment on the istaroxime clinical development plan. In addition, we plan to seek scientific advice from the European Medicines Agency (EMA) in the fourth quarter of 2019. The FDA recently granted Fast Track designation for istaroxime for the treatment of acute heart failure.  

AEROSURF (lucinactant for inhalation) is an investigational combination drug/device product that we are developing to improve the management of RDS in premature infants who may not have fully developed natural lung surfactant and may require surfactant therapy to sustain life.  Surfactants in the US are animal-derived and must be administered using endotracheal intubation, frequently with mechanical ventilation, invasive procedures that may result in serious respiratory conditions and other complications.  AEROSURF is designed to deliver aerosolized KL4 surfactant noninvasively using our proprietary aerosol delivery systems (ADS) technology, without invasive procedures.  In 2017, we completed a phase 2b clinical trial, which did not meet the primary endpoint of reduction in nCPAP failure at 72 hours, due in large part, we believe, to an unexpected rate of treatment interruptions that occurred in about 24% of active enrollments, predominantly in the 50-minute dose group. We believe the interruptions were primarily related to certain of the prototype phase 2 ADS devices with specific lots of disposable cartridge filters that had a higher tendency to clog.  After excluding patients in the 50-minute dose group whose dose was interrupted, in accordance with the predesignated statistical plan, we observed a meaningful treatment effect in line with our desired targeted outcome. The overall data suggest that the safety and tolerability profile of AEROSURF was generally comparable to the control group. Reported adverse events and serious adverse events were those that are common and expected among premature infants with RDS and comparable to the control group. We are currently engaged in preparatory work for an additional AEROSURF clinical bridging study that is designed, among other things, to clinically evaluate the design and performance of our new phase 3 ADS.  We expect to initiate this clinical trial in the fourth quarter of 2019. This trial will not be powered to establish statistical significance but will generate additional higher dose treatment data to augment the higher dose data obtained in the phase 2b clinical trial.  We believe that AEROSURF, if approved, has the potential to reduce the number of premature infants who are subjected to invasive surfactant administration, and potentially provide transformative clinical and pharmacoeconomic benefits. The FDA has granted Fast Track designation for our KL4 surfactant (including AEROSURF) to treat RDS.

We are also assessing potential development pathways to secure marketing approval for lyophilized KL4 surfactant as an intratracheal instillate for the treatment and/or prevention of RDS. Lyophilized KL4 surfactant is the drug product component of AEROSURF and a lyophilized dosage form of liquid KL4 surfactant, which was approved by the FDA in 2012 (SURFAXIN®). We previously discussed with the FDA a potential approach and plan potentially to re-engage with the FDA in the second half of 2019. If we can define an acceptable development plan that is achievable from a cost, timing and resource perspective, we may seek approval to treat premature infants who, because they are unable to breathe on their own or other reason, are not candidates for AEROSURF.

We also believe that our lyophilized KL4 surfactant may potentially support a product pipeline to address a broad range of serious respiratory conditions in children and adults. We have pursued a number of early exploratory research efforts to identify potential product candidates, including a collaboration with Eleison Pharmaceuticals, Inc., a specialty pharmaceutical company developing life-saving therapeutics for rare cancers, to assess the feasibility of using our ADS potentially to deliver Eleison’s inhaled lipid cisplatin (ILC), and, with support from the National Institutes of Health (NIH), to address certain respiratory conditions. Once we have secured additional funding to further advance our lead development programs, we plan to assess the status of these programs and potentially redouble our efforts to advance one or more of these opportunities.

Our fourth product candidate is rostafuroxin for the treatment of genetically associated hypertension. Rostafuroxin targets resistant hypertensive patients with a specific genetic profile, which is found in approximately 20% to 25% of the adult hypertensive population. We believe that rostafuroxin may reduce or normalize blood pressure in this genetically identified subset of patients and may reduce the risk of hypertension-related sequelae beyond the level normally associated with the absolute reduction of blood pressure, per se, because the molecular mechanism blocked by rostafuroxin may also be involved in organ damage. CVie Therapeutics completed three clinical trials assessing rostafuroxin, including a phase 2b clinical trial which was conducted in two parts, one in Caucasian patients in Italy and one in Chinese patients in Taiwan. While the blood pressure reduction in Caucasians was notable, there was no blood pressure response in Chinese patients. We are analyzing the results of these studies potentially to understand the reasons for the limited response in Chinese patients. We currently are working to finalize the drug formulation and define drug product analytical methods. If successful, we then plan to engage in business development activities potentially to out-license rostafuroxin to a larger company that has an interest in and/or operates in the very large and broad antihypertension market.

Business and Program Updates

The reader is referred to, and encouraged to read in its entirety, Item 1 – Business in our Annual Report on Form 10-K for the year ended December 31, 2018 that we filed with the Securities and Exchange Commission (SEC) on April 16, 2019, as amended by the Form 10-K/A that we filed with the SEC on April 23, 2019 (collectively, 2018 Form 10-K), and our Quarterly Reports on Form 10-Q filed thereafter, which contain discussions of our business and business plans, as well as information concerning our proprietary technologies and our current and planned development programs. 

AEROSURF

With respect to our AEROSURF® development program, on May 9, 2019, we announced that we had presented a new post-hoc analysis from our phase 2b AEROSURF clinical trial suggesting that AEROSURF may reduce the overall incidence and severity of bronchopulmonary dysplasia (BPD) in premature infants with RDS, regardless of whether the infant was ultimately intubated. The new data were presented in May 2019 at the Pediatric Academic Societies (PAS) Meeting, the leading event for academic pediatrics and child health research. 

Istaroxime

On May 30, 2019, we announced new data from the phase 2b study of istaroxime which was presented at a late-breaker session of the European Society of Cardiology (ESC) 2019 Heart Failure Congress. The study achieved its primary endpoint by demonstrating a significant improvement (p<0.05) in cardiac function at both istaroxime study doses. The study further showed that stroke volume, a key secondary endpoint, was substantially increased. Importantly, certain toxicities and complications experienced with many existing acute heart failure therapies were not observed in istaroxime-treated patients, including no signals of increased arrhythmias or increased troponin levels, a common marker of heart muscle damage. Istaroxime significantly increased or maintained systolic blood pressure during treatment which may have contributed to short term trend toward improvement in renal function.

The phase 2b study was conducted with 120 patients and was designed to assess the safety and efficacy of 24-hour infusions of two doses of istaroxime (0.5 and 1.0 µg/kg/min), compared to placebo, in the treatment of patients with acute heart failure. The primary endpoint of this study was a change from baseline to 24 hours after start of infusion (Day 1) in E/e’ with istaroxime 0.5 or 1.0 µg/kg/min vs. placebo. The E/e’ ratio is a marker of the function of the left ventricle (LV) of the heart and was measured using doppler echocardiography read by a central laboratory. Secondary endpoints included change in other parameters of cardiac function, such as diastolic function (E/A), stroke volume (SVI), left ventricle ejection fraction (LVEF), LV volumes, left atrial (LA) area, interior vena cava (IVC) diameter. Investigators of the study concluded that a 24-hour infusion of istaroxime was associated with significant improvements in cardiac function, in both dosing groups, with a mean E/e’ of -4.55 for the 0.5 µg/kg/min group and -3.16 for the 1.0 µg/kg/min group, compared with mean placebo E/e’ ratios of -1.55 and -1.08, respectively.

Twenty-four-hour infusions of istaroxime were also associated with substantial increases in stroke volume in both dosing groups, with a mean SVI value of 5.33 ml/beat/m² for the 0.5 µg/kg/min group and 5.49 ml/beat/m² for the 1.0 µg/kg/min group, compared with the mean placebo SVI of 1.65 ml/beat/m² and 3.18 ml/beat/m², respectively. Importantly, subjects also maintained or increased systolic blood pressure (SBP), with a mean change in SBP of 2.82 mmHg for the 0.5 µg/kg/min group and 6.1 mmHg for the 1.0 µg/kg/min group, compared with the mean placebo SBP values of -2.47 mmHg and 2.7 mmHg, respectively.

Istaroxime was generally well tolerated. Istaroxime did not appear to be associated with an increase in risk for arrhythmias or increases in cardiac troponin T. Cardiovascular-related adverse events were 23 percent for placebo, 10 percent for istaroxime low dose, and 18 percent for istaroxime high dose with cardiac failure occurring in 3 percent, 5 percent and 8 percent of placebo, low and high dose of istaroxime patients, respectively. These cases of cardiac failure were reported by the investigator as “worsening of heart failure” symptoms that occurred approximately 10-14 days after study drug administration and were not considered to be drug related. The most common adverse drug reactions reported included pain at infusion site, generally associated with use of short catheters, and dose-related gastrointestinal adverse events in 5 percent, 10 percent and 35 percent of placebo, low and high dose istaroxime respectively.

Eleison Pharmaceuticals LLC

In June 2019, we and Eleison Pharmaceuticals LLC announced positive results of a feasibility study using our ADS aerosolization technology to deliver Eleison's inhaled lipid cisplatin (ILC). The results demonstrate the feasibility to aerosolize ILC for potential use in thoracic oncology treatment.

Manufacturing

We are currently in discussions with Pharma Services Group, Patheon, part of Thermo Fisher Scientific (Patheon), concerning the winddown of our Master Services Agreement dated as of October 24, 2013 for the manufacture of lyophilized KL4 surfactant for AEROSURF.  Patheon has indicated that it will continue to manufacture lyophilized KL4 surfactant to support the planned AEROSURF clinical trial and will assist us with the technology transfer to another contract manufacturing organization.  We plan to seek proposals for the technology transfer and future manufacturing of lyophilized KL4 surfactant from certain entities that we have identified that we believe have appropriate experience to support this program.

Other Events

Effective August 7, 2019, the holders of a majority interest of our common stock authorized a reverse split of our common stock at any time prior to September 30, 2020 at a ratio of not less than 10-for-11 and not greater than 1-for-3 (Reverse Split), on such terms as may be determined in the sole discretion of our Board of Directors. The Board of Directors may decide in its discretion to implement a Reverse Split or not to implement a Reverse Split.

This Quarterly Report on Form 10-Q includes information concerning our AEROSURF clinical and device development programs. The AEROSURF phase 2b clinical trial has been supported to date, in part, by a $2.6 million Phase IIb award under a Small Business Innovation Research (SBIR) grant from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) under parent award number R44HL107000.  In addition, we received funding under a Phase II SBIR grant from the National Institute of Allergy and Infectious Diseases (NIAID) under parent grant number R44AI102308.

RESULTS OF OPERATIONS

Operating Loss and Net Loss

The operating loss for the three months ended June 30, 2019 and 2018 was $6.5 million and $3.0 million, respectively. The increase in operating loss from 2018 to 2019 was due to a $2.6 million increase in operating expenses, a $0.7 million decrease in grant revenue, and a $0.2 million decrease in license revenue with affiliate.

The operating loss for the six months ended June 30, 2019 and 2018 was $13.2 million and $7.9 million, respectively. The increase in operating loss from 2018 to 2019 was due to a $4.2 million increase in operating expenses, a $0.7 million decrease in grant revenue, and a $0.4 million decrease in license revenue with affiliate.

The net loss for the three months ended June 30, 2019 and 2018 was $6.4 million and $3.1 million, respectively. The net loss for the six months ended June 30, 2019 and 2018 was $13.0 million and $7.6 million, respectively.

Grant revenue

For the three and six months ended June 30, 2018, we recognized grant revenue of $0.7 million. Grant revenue for the three and six months ended June 30, 2018 consists of funds received and expended under a Phase II Small Business Innovation Research Grant (SBIR) from the National Heart, Lung, and Blood Institute (NHLBI) of the NIH to support the AEROSURF phase 2b clinical trial (AEROSURF Grant).

License Revenue with Affiliate

License revenue with affiliate represents revenue from a License Agreement with Lee’s Pharmaceutical (HK) Ltd. (Lee’s (HK)), an affiliate of Lee’s Pharmaceutical Holdings Limited (Lee’s), which together with its affiliates is our largest shareholder, and constitutes a contract with a customer accounted for in accordance with ASC Topic 606. As of June 30, 2019, all revenue related to the License Agreement has been recognized and no future material performance obligations are due.

Research and Development Expenses

Our research and development expenses are charged to operations as incurred and we account for such costs by category rather than by project. As many of our research and development activities likely form the foundation for the potential development of multiple product candidates, including istaroxime, our KL4 surfactant and drug delivery technologies, and rostafuroxin, they are expected to benefit more than a single project. For that reason, we cannot reasonably estimate the costs of our research and development activities on a project-by-project basis. We believe that tracking our expenses by category is a more accurate method of accounting for these activities. Our research and development costs consist primarily of expenses associated with (a) product development and manufacturing, (b) clinical, medical and regulatory operations, and (c) direct preclinical and clinical development programs. We also account for research and development and report annually by major expense category as follows: (i) salaries and benefits, (ii) contracted services, (iii) raw materials, aerosol devices and supplies, (iv) rents and utilities, (v) depreciation, (vi) contract manufacturing, (vii) travel, (viii) stock-based compensation and (ix) other. 

Research and development expenses by category for the three and six months ended June 30, 2019 and 2018 are as follows: 

Research and development expenses include non-cash charges associated with stock-based compensation and depreciation of $0.5 and $0.1 million for the three months ended June 30, 2019 and 2018, respectively, and $1.1 and $0.2 million for the six months ended June 30, 2019 and 2018, respectively.

Product Development and Manufacturing

Product development and manufacturing includes (i) manufacturing operations, both in-house and with contract manufacturing organizations (CMOs), technology transfer and validation activities, quality assurance and analytical chemistry capabilities that support the manufacture of our drug product candidates used in research and development activities, including istaroxime, KL4 surfactant and rostafuroxin, and our medical devices, including our ADS; (ii) design and development activities related to our ADS for use in our AEROSURF clinical development program; and (iii) pharmaceutical and manufacturing development activities, including development of a lyophilized dosage form of our KL4 surfactant and rostafuroxin. These costs include employee expenses, facility-related costs, depreciation, costs of drug substances (including raw materials), supplies, quality control and assurance activities, analytical services, and expert consultants and outside services to support pharmaceutical and device development activities.

Product development and manufacturing expenses decreased $0.6 million and $1.2 million, respectively, for the three and six months ended June 30, 2019 compared to the same periods in 2018 due to a reduction of design and development activities on the phase 3 ADS following completion of the design verification activities in mid-2018.

Clinical, Medical and Regulatory Operations

Clinical, medical and regulatory operations include (i) medical, scientific, preclinical and clinical, regulatory, data management and biostatistics activities in support of our research and development programs; and (ii) medical affairs activities to provide scientific and medical education support for our product candidates under development. These costs include personnel, expert consultants, outside services to support regulatory and data management, symposiums at key medical meetings, facilities-related costs, and other costs for the management of clinical trials.

Clinical, medical and regulatory operations expenses increased $1.0 million and $1.4 million, respectively, for the three and six months ended June 30, 2019 compared to the same periods in 2018 due to (i) an increase of $0.5 million and $0.9 million, respectively, in non-cash, stock compensation expense as a result of employee stock option grants in the fourth quarter of 2018 and the first quarter of 2019; (ii) an increase in employee-related incentive bonus accruals of $0.2 million and $0.3 million, respectively; and (iii) a $0.2 million increase in each period in personnel costs.

Direct Preclinical and Clinical Development Programs

Direct preclinical and clinical development programs include (i) development activities, toxicology studies and other preclinical studies; and (ii) activities associated with conducting clinical trials, including patient enrollment costs, clinical site costs, clinical device and drug supply, and related external costs, such as consultant fees and expenses.

Direct preclinical and clinical development programs expenses increased $0.2 million and $0.5 million, respectively, for the three and six months ended June 30, 2019 compared to the same periods in 2018 due to costs associated with continued clinical development of istaroxime and AEROSURF and preclinical activities related to potential follow-on product candidates in acute heart failure.

Research and Development Projects – Updates

For our lead clinical programs, istaroxime and AEROSURF, we have been engaged in start-up activities related to the next planned clinical studies. With respect to rostafuroxin, we continue to focus on product development work for final formulation to potentially support our planned business development activities.

General and Administrative Expenses

General and administrative expenses consist of costs for executive management, business development, intellectual property, finance and accounting, legal, human resources, information technology, facility, and other administrative costs.

General and administrative expenses increased $2.0 million and $3.5 million, respectively, for the three and six months ended June 30, 2019 compared to the same periods in 2018 due to (i) an increase of $1.1 million and $1.8 million, respectively, in non-cash, stock compensation expense as a result of employee stock option grants in the fourth quarter of 2018 and the first quarter of 2019; (ii) an increase of $0.3 million and $0.6 million, respectively, in employee-related incentive bonus accruals; and (iii) an increase of $0.6 million and $0.9 million, respectively, in professional fees, taxes, and insurance.

Other Income and (Expense) 

The increase in interest income for the three and six months ended June 30, 2019 compared to the same periods in 2018 is due to the increase in cash and marketable securities available-for-sale as a result of the Private Placement Financing.

For the three and six months ended June 30, 2019, interest expense consists of interest expense associated with collaboration and device development payables and with loans payable. For the three and six months ended June 30, 2018, interest expense primarily consists of interest expense associated with amounts due to Battelle Memorial Institute under a 2014 Collaboration Agreement, and device development payables and interest expense related to $2.5 million in loans payable to LPH.

For the three and six months ended June 30, 2019, other income primarily consists of $0.1 million and $0.3 million, respectively, in gains on foreign currency translation. For the three and six months ended June 30, 2018, other income primarily consists of proceeds from the sale of Commonwealth of Pennsylvania research and development tax credits.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 2019, we had cash and cash equivalents of $6.1 million and available-for-sale, marketable securities of $2.5 million, and current liabilities of $15.5 million, including $8.0 million of Loans payable (see, Note 7- Loans Payable).  As of August 9, 2019, we believe that we have sufficient resources (including marketable securities) available to support our development activities, business operations and debt service through October 2019.

Although we believe that the CVie Acquisition and a private placement financing that we also closed on December 21, 2018 (the Private Placement Financing) better position us to raise the additional capital needed to fund our existing development programs, support our operations and business development efforts, and satisfy our obligations beyond October 2019, we do not have sufficient cash and cash equivalents for at least the next year following the date that the financial statements are issued. These conditions raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued.

To alleviate the conditions that raise substantial doubt about our ability to continue as a going concern, management plans, and is currently actively engaged in discussions with various parties, to secure additional capital, potentially through a combination of public or private equity offerings and strategic transactions, including potential alliances and drug product collaborations focused on specified geographic markets. However, none of these alternatives are committed at this time.  There can be no assurance that we will be able to complete any public or private equity offerings on acceptable terms, or in amounts required to support our operations, if at all, or identify and enter into any strategic transactions that will provide the capital that we will require. If none of these alternatives is available, or if available, we are unable to raise sufficient capital through such transactions, we will not have sufficient cash resources and liquidity to fund our business operations for at least the next year following the date that the financial statements are issued. Accordingly, management has concluded that substantial doubt exists with respect to our ability to continue as a going concern through one year after the issuance of the accompanying financial statements.

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business, and do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

As of June 30, 2019, there were 120.0 million shares of common stock and 5.0 million shares of preferred stock authorized under our Certificate of Incorporation, and approximately 72.0 million shares of common stock and 5.0 million shares of preferred stock available for issuance and not otherwise reserved.

Cash Flows

Cash outflows for the six months ended June 30, 2019, consist of $15.4 million used for ongoing operating activities and $0.6 million used for financing activities, offset by cash inflows for the six months ended June 30, 2019 of $11.3 million for investing activities.

Operating Activities

Net cash used in operating activities for the six months ended June 30, 2019 and 2018 was $15.4 million and $6.3 million, respectively. Net cash used in operating activities is a result of our net losses for the period, adjusted for non-cash items and changes in working capital. The increase in net cash used in operating activities is due to the payment of CVie Acquisition costs and Private Placement Financing costs and the payment of pre-existing obligations with the proceeds of the Private Placement Financing. The net cash used in operating activities for the six months ended June 30, 2018 reflected our cash conservation efforts during that period.

Investing Activities

Net cash provided by investing activities for the six months ended June 30, 2019 represents $11.5 million related to the sale of marketable securities, partially offset by $0.2 million in purchase of property and equipment.

Financing Activities

Net cash used in financing activities for the six months ended June 30, 2019 was $0.6 million and represents $0.4 million in principal payments on our Loan payable and $0.2 million related to withholding tax payments for net share settlements of restricted stock units.

Net cash provided by financing activities for the six months ended June 30, 2018 was $5.0 million and represents loan proceeds of $1.5 million and $1.0 million related to loan agreements with LPH and $2.6 million from a private placement offering with LPH II, a wholly-owned subsidiary of Lee’s, from which we received net proceeds of approximately $2.5 million.

The following sections provide a more detailed discussion of our available financing facilities.

Loans Payable

In January 2018 and March 2018, LPH Investments Limited (LPH), an affiliate of Lee’s, agreed to lend us $1.5 million and $1.0 million, respectively, to support our AEROSURF development activities and sustain our operations while we sought to identify and advance one or more potential strategic initiatives as defined in the related loan agreements (Funding Event).  The loans accrued interest at a rate of 6% per annum and would mature upon the earlier of the closing date of the Funding Event or December 31, 2018. To secure our obligations under these loans, we granted LPH a security interest in substantially all our assets pursuant to the terms of a Security Agreement with LPH dated March 1, 2018 (LPH Security Agreement). Effective December 5, 2018, LPH assigned all outstanding loans to us to LPH II Investment Limited (LPH II). In connection with the Private Placement Financing, we converted to equity $6.0 million of the then outstanding loan payable obligations to LPH II on the same terms as those of the investors in the private placement. Included in the conversion were the $1.5 million and $1.0 million loans.

Assumption of bank debt as part of the CVie Acquisition

As part of the CVie Acquisition, we assumed approximately $4.5 million in a bank credit facility due in March 2020.

In September 2016, CVie entered into a 12-month revolving credit facility of approximately $2.9 million with O-Bank Co., Ltd. to finance operating activities. The facility was later renewed and increased to approximately $5.8 million in September 2017. The credit facility was guaranteed by Lee’s, which pledged bank deposits in the amount of 110% of the actual borrowing amount.  Interest, payable in cash on a monthly basis, is determined based on 90-day TAIBOR (the Taipei Interbank Offer Rate) plus 0.91%. The credit facility will expire on September 11, 2019 and matures six months after the expiration date, on March 11, 2020.

As of June 30, 2019, the outstanding principal was approximately $4.5 million.

Assumption of Lee's debt as part of the CVie Acquisition

As part of the CVie Acquisition, we assumed approximately $3.5 million of debt payable to Lee’s Pharmaceutical International Limited (Lee’s International).

From April 24, 2018 to November 16, 2018, CVie entered into four separate agreements to borrow an aggregate of approximately $3.5 million from Lee’s International. The terms of the loan agreements are identical where the interest, payable in cash upon maturity, is 4% per annum and each of the four separate loans will mature one year from the effective date as follows: $0.5 million in April 2019; $0.3 million in September 2019; $0.2 million in October 2019; and $2.5 million in November 2019.

During the quarter ended March 31, 2019, we made payments of $0.45 million against the April 2018 loan and paid the remaining $50,000 balance plus accrued interest in April 2019. As of June 30, 2019, the outstanding principal of the loans with Lee’s International was $3.0 million.

Loan payable to Bank Direct Capital Finance

In May 2019, we entered into an insurance premium financing and security agreement with Bank Direct Capital Finance (Bank Direct) related to our director and officer insurance. Under the agreement, we have financed $0.7 million in premiums at a 5.35% annual interest rate. Payments of approximately $80,000 are due monthly through March 2020. As of June 30, 2019, the outstanding principal of the loan was $0.6 million.

Not applicable.

Evaluation of disclosure controls and procedures 

Our management, including our President and Chief Executive Officer (principal executive officer) and our Senior Vice President and Chief Financial Officer (principal financial officer), does not expect that our disclosure controls or our internal control over financial reporting will prevent all error and all fraud. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. 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. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our President and Chief Executive Officer and our Senior Vice President and Chief Financial Officer have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our President and Chief Executive Officer and our Senior Vice President and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our President and Chief Executive Officer and our Senior Vice President and Chief Financial Officer, to allow for timely decisions regarding required disclosures, and recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in internal control

There were no changes in our internal control over financial reporting identified in connection with the evaluation described above that occurred during the quarter ended June 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

We are not aware of any pending legal actions that would, if determined adversely to us, have a material adverse effect on our business and operations.

We have from time to time been involved in disputes and proceedings arising in the ordinary course of business, including in connection with the conduct of our clinical trials. In addition, as a public company, we are also potentially susceptible to litigation, such as claims asserting violations of securities laws. Any such claims, with or without merit, if not resolved, could be time-consuming and result in costly litigation. There can be no assurance that an adverse result in any future proceeding would not have a potentially material adverse effect on our business, results of operations and financial condition.

Investing in our securities involves risks. In addition to any risks and uncertainties described elsewhere in this Quarterly Report on Form 10-Q, stockholders and potential investors should carefully consider the risks and uncertainties discussed in Item 1A. Risk Factors in our 2018 Form 10-K and our Quarterly Reports on Form 10-Q filed thereafter. These risks are not the only risks that could materialize. Additional risks and uncertainties not presently known to us or that we currently consider to be immaterial may also impair our business operations and development activities. Should any of the risks and uncertainties described in our 2018 Form 10-K and our Quarterly Reports on Form 10-Q filed thereafter actually materialize, our business, financial condition and/or results of operations could be materially adversely affected, the trading price of our common stock could decline and a stockholder could lose all or part of his or her investment. In particular, the reader’s attention is drawn to the discussion in Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.

Risks Related to Capital Resource Requirements

As of August 9, 2019, we believe our resources (including marketable securities) are only sufficient to support our planned development activities, business operations and debt service through October 2019. If we do not secure additional capital to support our future activities before our existing cash resources are exhausted, we likely will be unable to continue as a going concern.

As of June 30, 2019, we had cash and cash equivalents of $6.1 million and available-for-sale, marketable securities of $2.5 million, and current liabilities of $15.5 million, including $8.0 million of loans payable. Although we believe that the CVie Acquisition and the concurrent Private Placement Financing may better position us to raise the additional capital needed to fund our development programs, including the istaroxime and AEROSURF clinical trials and other program activities; support our operations and business development efforts, and satisfy our obligations beyond October 2019, we expect to continue to incur significant losses and require significant additional capital to advance our development programs, support our operations and business development efforts, and satisfy existing obligations. These conditions raise substantial doubt about our ability to continue as a going concern.

We have not yet established an ongoing source of revenue sufficient to cover our operating costs and allow us to continue as a going concern. Our ability to continue as a going concern is dependent on our ability to raise additional capital. We plan, and are currently actively engaged in discussions with various parties, to secure the additional capital that we require potentially from a combination of public or private equity offerings and strategic transactions, including potential alliances and drug product collaborations focused on specified geographic markets; however, none of these alternatives are committed at this time and there can be no assurance that we will be successful in identifying and completing such a transaction in the future. If we are unable to identify any alternative and consummate one or more transactions on terms that are acceptable to us, or if we are unable to raise sufficient capital through such transactions, or within a time that would support our capital requirements, we likely will not have sufficient cash resources and liquidity to fund our business operations, which could significantly limit our ability to continue as a going concern. If we are unable to raise the required capital, we may be forced to curtail all of our activities and, ultimately, cease operations.

Risks related to Manufacturing Development and Manufacturing

We depend on third party contract manufacturing organizations (CMOs) to manufacture our drug products and APIs, and manufacture and assemble our medical devices.  In addition, we are currently contemplating process changes and/or technology transfers with certain of our CMOs to support our clinical development activities. If we undertake to transition to a new manufacturer or supplier, this exposes us to risks that may affect our ability to maintain inventory supplies of our clinical materials and could potentially delay our research and development activities.

We depend upon single-source suppliers to provide our requirements for AEROSURF drug product and APIs and are currently working with our CMOs to assure that we will have sufficient inventory to support our planned AEROSURF clinical activities. In addition, we are currently discussing the winddown of our AEROSURF drug product manufacturing agreement.  In that regard, our CMO has indicated a willingness to continue manufacturing on an interim basis to build drug product inventory to support our planned AEROSURF clinical bridging study. However, there can be no guarantee that they will remain willing or able to do so. Furthermore, there can be no guarantee that we will be able to find a successor when needed or enter into agreements on terms and conditions favorable to us, and in a timely manner. If our inventory supplies of lyophilized KL4 surfactant drug product or APIs are insufficient to satisfy demand, there could be an adverse impact on our current clinical development programs, our development activities and our business.

If any of the foregoing risks were to arise, our development programs could be delayed, or ability to maintain continuity of supply could be impaired, which could have a material adverse impact on our operations and our business.
