Diffusion Pharmaceuticals Reports Third Quarter 2020 Financial Results and Provides Business Updates

CHARLOTTESVILLE, Va., Nov. 12, 2020 (GLOBE NEWSWIRE) — Diffusion Pharmaceuticals Inc. (Nasdaq: DFFN) (“Diffusion” or the “Company”) today reported financial results for the three and nine months ended September 30, 2020 and provided certain updates on its development program for its lead product candidate, trans sodium crocetinate (“TSC”), which is being developed to enhance the diffusion of oxygen to tissues with low oxygen levels, also known as hypoxia, a serious complication of many of medicine’s most intractable and difficult-to-treat conditions.

Third Quarter Results & Recent Developments

• Strengthened leadership team with additions and appointments to key management positions, including pharmaceutical industry veterans Jane Hollingsworth, as director, Robert Cobuzzi, Ph.D., as president and chief executive officer, and Chris Galloway, M.D., as chief medical officer, as well as Bill Elder, J.D., as general counsel.

• Ended quarter with $21.9 million in cash and cash equivalents.

• Announced dosing of first two patients in Phase 1b clinical trial evaluating TSC in hospitalized COVID-19 patients (the “100-303 COVID Trial”) with primary endpoint of evaluating safety and tolerability of TSC administered every six hours for up to 15 days, a more frequent dosing regimen than has been used in the Company’s previous clinical studies.

• As of November 11, 2020, patient enrollment continues, and no dose-limiting toxicities have been observed.

Near-Term Strategy

• Ongoing review of existing TSC development program with plans to modify the program and accomplish two principal strategic objectives:

• Optimize the clinical dose and dosing frequency for TSC.

• Evaluate TSC in clinical models designed to establish proof of concept for improvement in oxygenation following administration of TSC.

• Designing and initiating additional studies in effort to accomplish strategic objectives:

• Evaluating possibility of expanding 100-303 COVID Trial to include additional doses administered on the same regimen, assuming successful and timely completion of currently planned doses and final regulatory approval of pending protocol amendment to effect change.

• Designing additional clinical studies intended to evaluate (i) the effects of TSC using short-term experimental models of oxygenation with the expected primary objective of establishing proof of concept for improvement of tissue oxygen levels and certain other clinical parameters and (ii) depending on whether or not the Company decides to implement the expansion of the 100-303 COVID Trial, additional doses of TSC on a more frequent dosing regimen.

• Diffusion expects to fully fund these studies with cash-on-hand.

• Diffusion intends to provide certain additional details regarding the design of these new studies in January 2021 and to initiate the studies during the first quarter of 2021. The Company also now expects the 100-303 COVID Trial, whether or not the Company decides to implement the expansion described above, to be completed with topline data available by the end of first quarter of 2021.

Other Events

• Diffusion currently intends to participate in two virtual, biopharmaceutical and biotechnology industry conferences in mid-January 2021 – Biotech Showcase and the H.C. Wainwright 2021 Bioconnect Conference – and to provide its next update regarding its development program for TSC at that time.

• Launched new website design at www.diffusionpharma.com.

“Hypoxia can be a serious complication of a multitude of acute and chronic disease processes in patients of all ages and represents a continued area of unmet need that spans multiple therapeutic areas. I am excited about our development plans, which we believe will clarify TSC’s mechanism of action in controlled human studies of oxygenation. We intend to use these data to inform and evaluate our further development opportunities for TSC, as well as potential patient populations and indications,” said Chris Galloway, M.D., Chief Medical Officer of Diffusion.

“Diffusion has experienced a lot of changes over the past few months. While we continue to refine our vision for the Company, we are pleased with the progress we made during the third quarter and we are excited to begin implementing our plans during the coming months,” said Robert Cobuzzi, Ph.D., Chief Executive Officer of Diffusion. “We believe our near-term strategy will significantly improve the probability of development success for TSC by providing the opportunity to optimize dosing and obtain a clear clinical signal supporting the potential value of TSC’s mechanism of action across a broad range of conditions in which hypoxia remains a significant obstacle to effective treatment.”

Third Quarter Financial Results

Research and development (“R&D”) expenses were $3.1 million during the third quarter of 2020, compared with $1.7 million during the third quarter of 2019. A significant portion of the increase, $1.4 million, was attributable to expenses related to the initiation of the Company’s ongoing clinical trial evaluating TSC in COVID-19 patients. In addition, R&D expenses included $0.1 million related to winding down the Company’s Phase 2 stroke trial.

General and administrative (“G&A”) expenses were $2.1 million during the third quarter of 2020, compared with $1.3 million during the third quarter of 2019. The increase was primarily due to a $0.2 million increase in professional fees and a $0.6 million increase in salaries, wages and stock-based compensation expenses, including non-recurring expenses related to the retirement, resignation and separation of the Company’s former Chief Executive Officer in September 2020.

The Company recognized income tax benefits of $0.8 million and $0.2 million during the third quarters of 2020 and 2019, respectively. In both periods, the recognized benefit reflects the Company’s utilization of indefinite deferred tax liabilities as a source of income against indefinite lived portions of its deferred tax assets.

Diffusion had cash and cash equivalents of $21.9 million as of September 30, 2020, compared with $14.2 million as of December 31, 2019, and believes its cash and cash equivalents are sufficient to fund operating expenses and capital expenditures into the fourth quarter of 2022.
