Moleculin Biotech, Inc. Reports Financial Results for the Quarter Ended June 30, 2020

HOUSTON, Aug. 12, 2020 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) (Moleculin or the Company), a clinical stage pharmaceutical company with a broad portfolio of drug candidates targeting highly resistant tumors and viruses, announced its financial results for the quarter ended June 30, 2020 and provided a business update.

Management Discussion

Walter Klemp, Chairman and CEO of Moleculin, stated, "Despite the difficult backdrop resulting from the global pandemic, we made tremendous progress across all three of our core technologies, particularly in our infectious disease platform of antimetabolites, bolstered our financial position, and added to our experienced leadership team. Importantly, we were pleased to progress our efforts to combat COVID-19, as WP1122, which is often referred to as a "prodrug" of 2-DG and one of our antimetabolites, demonstrated its potential in a number of pre-clinical studies and independent research publications. Independent research found 2-deoxy-D-glucose ("2-DG") reduced replication of SARS-CoV-2, the virus that causes COVID-19, by 100% in in vitro testing. A second independent publication at the University of Campinas in São Paulo further demonstrated the potential of WP1122's mechanism of action as it showed SARS-CoV-2 infection is supported by elevated glucose levels and that inhibition of glycolysis with 2-DG effectively eliminated viral load in vitro. Additionally, two rounds of preclinical testing at one independent lab confirmed by a round of in-vitro testing at a second independent lab in a separate virus host cell line continued to demonstrate WP1122's antiviral activity in SARS-CoV-2. We are very encouraged by this early demonstration of efficacy and are now even more motivated to continue to drive its development. Based on guidance from the FDA, we are pursuing additional studies in animal models, which we believe is the critical path to our expected timing, to further assess WP1122's antiviral capability, with the goal of a possible IND filing in 2020, in preparation for beginning a human clinical trial thereafter."

Mr. Klemp continued, "Although we have expanded the scope and focus of our WP1122 program, our lead candidate, Annamycin, a 'next generation anthracycline' demonstrating little to no cardiotoxicity, still remains one of our key priories. The results from the Phase 1 portion of our US Phase 1/2 clinical trial in acute myeloid leukemia (AML) have been highly encouraging, as Annamycin met its primary endpoint and demonstrated a clean safety profile with no evidence of cardio-toxicity when delivered to patients at or below the lifetime maximum anthracycline dose established by the FDA. Following these strong results and an independent review of Annamycin, in which the independent expert concluded that he 'does not see evidence of cardio-toxicity', we received authorization from the Polish Department of Registration of Medicinal Products to increase the Phase 1 dose escalation portion of our clinical trial for the treatment of AML. We believe this to be a substantial development in the acceleration of our trial as it allows for the increase in dose escalation increments between cohorts from 30 mg/m(2) to 60 mg/m(2). This will enable our next cohort to increase to 300 mg/m(2), assuming all requirements for safety are met with the 240 mg/m(2) cohort, for which we are currently recruiting. With these dosing expectations, the Company believes that European dosing will increase in 2020, providing for a recommended Phase 2 Dose to be established in 2021. In addition to driving the development of Annamycin, during the second quarter we saw the advancement of WP1066, the lead molecule in Moleculin's portfolio of immune stimulators and modulators of transcription. Importantly, Emory University began recruiting and treating patients in its Phase 1 clinical trial of WP1066 for the treatment of brain tumors in children. We are pleased by the progress of the trial, which has now enrolled and treated three patients. The Emory study, which is being at conducted at the Aflac Cancer & Blood Disorders Center at Children's Healthcare of Atlanta, represents a new approach for treating pediatric brain cancer and benefits from safety data generated in the ongoing clinical trial of WP1066 in adult brain tumors being conducted by MD Anderson Cancer Center."

Mr. Klemp concluded, "With our focus on the continued progression of our candidates and our expansion into infectious disease, we found it prudent to bolster our expertise. As a result, we made several strategic additions to our team at Moleculin. In March, we added Dr. Hongbo Zhai, who has two decades of research and development experience in pharmaceuticals and biotechnology, to our Science Advisory Board. To complement our expanded focus on COVID-19, we then added to our Science Advisory Board Dr. Dominique Schols, a leading virologist at the Rega Institute in Leuven, Belgium, and Dr. Richard Whitley, head of the NIAID Antiviral Drug Discovery and Development Center. With the additions to our team and the progress we made in all three of our programs, we believe we are well positioned to continue to build on the momentum we have achieved thus far in 2020."

Financial Results for the Quarter Ended June 30, 2020

Research and development (R&D) expense was $3.3 million and $2.1 million for the three months ended June 30, 2020 and 2019, respectively. The increase of $1.2 million is mainly related to increased clinical trial activity, increased license fees and costs related to sponsored research agreements, costs related to manufacturing of additional drug product and two additional employees in R&D headcount.

General and administrative expense was $1.7 million and $1.5 million for the three months ended June 30, 2020 and 2019, respectively. The increase of $0.2 million was mainly attributable to increased stock-based compensation expense for annual employee stock options and increased costs for directors and officer's liability insurance.

Loss from operations for the second quarter was $5.0 million compared to a net loss of $3.6 million for the second quarter of 2019. This increase was largely due to the above-mentioned increase in R&D.

Net loss for the second quarter of 2020 was $10.1 million, compared to a net loss of $1.2 million in the second quarter of 2019, and was attributed to the above-mentioned increase in R&D and the change in fair value on revaluation of warrant liability associated with warrants issued in conjunction with stock offerings. Changes in our stock price can result in a material gain or loss during the quarter related to the revaluation of our warrant liability. The loss from the change in the fair value of the warrant liability for the second quarter of 2020 was $5.1 million compared to a gain of $2.4 million in the same quarter in 2019. This is a non-cash item.

Liquidity and Capital Resources

As of June 30, 2020, we had cash and cash equivalents of $16.7 million and prepaid expenses and other of $3.0 million. We also had $1.9 million of accounts payable and $1.8 million of accrued expenses. A significant portion of the accounts payable and accrued expenses are due to work performed in relation to our clinical trials. For the six months ended June 30, 2020 and 2019, we used approximately $9.3 million and $9.2 million of cash in operating activities, respectively, which represents cash outlays for research and development and general and administrative expenses in such periods. For the six months ended June 30, 2020 and 2019, net proceeds from financing activities were $15.3 million and $20.8 million, respectively, predominately from the sale of our common stock and the exercise of warrants. Cash used in investing activities for the six months ended June 30, 2020 and 2019 was approximately $0.02 million and $0.03 million, respectively.

We believe that our existing cash and cash equivalents as of June 30, 2020 plus the $1.9 million cash raised subsequent to the quarter will be sufficient to fund our planned operations into the first quarter of 2021, without the issuance of additional equity for cash. Any such issuances should extend the funding of our planned operations beyond the first quarter of 2021. Such plans are subject to our stock price, market conditions, changes in planned expenses depending on clinical enrollment progress, the use of drug product or a combination thereof.
