• Announced Thorough Evaluation of a Range of Potential Strategic Opportunities
• Continued GBM Study Start-up Activities
• Ended Quarter with $25.9 million in Cash, Cash Equivalents and Marketable Securities
  

CHARLOTTESVILLE, Va., Nov. 14, 2022 (GLOBE NEWSWIRE) -- Diffusion Pharmaceuticals Inc. (NASDAQ: DFFN) (“Diffusion” or the “Company”), a biopharmaceutical company developing novel therapies that may enhance the body’s ability to deliver oxygen to areas where it is needed most, today announced financial results for the quarter ended September 30, 2022, and provided a business update.

“As previously announced, we formalized our efforts to identify and evaluate strategic opportunities during the third quarter, and with our current assets, including trans sodium crocetinate (“TSC”) and our strong balance sheet, we believe these activities will effectively position us to meet the challenges of this dynamic market,” commented Robert Cobuzzi, Jr., Ph.D., President and Chief Executive Officer of Diffusion.

Dr. Cobuzzi continued, “While our process to evaluate strategic opportunities is ongoing, the Diffusion organization remains focused on executing our strategy to create value for our shareholders. We continue to prioritize progress towards the initiation of Study 200-208 and further exploration of potential accelerated pathways for regulatory approval of TSC, while taking steps to preserve capital without sacrificing meaningful growth opportunities.”

Business & Development Updates

Commenced Process to Evaluate Potential Strategic Opportunities: In October 2022, Diffusion announced that its Board of Directors authorized a thorough review and evaluation of a range of potential strategic opportunities in the interest of enhancing stockholder value including transactional opportunities to better leverage the potential of TSC and the Company’s other assets. The Company retained Canaccord Genuity LLC as its financial advisor and Dechert LLP as its legal counsel to assist with the review process.

Announced Plans for a Phase 2 Glioblastoma Trial: In July 2022, Diffusion announced alignment with the United States Food and Drug Administration (“FDA”) on the design of Diffusion’s Phase 2 clinical trial entitled “Open-Label, Dose-Escalation, Phase 2 Safety and Efficacy Study of TSC in Newly Diagnosed Glioblastoma (“GBM”) Patients when Administered with Standard of Care.” The study will include up to 9 patients in a dose-escalation phase, enrolling patients in a 3+3+3 design, to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of TSC at doses of 1.5 mg/kg, 2.0 mg/kg and 2.5 mg/kg administered in combination with concomitant standard of care radiotherapy plus temozolomide. An additional 17 subjects will be treated at the highest tolerable dose identified in the dose escalation phase. The primary objective of the study is to evaluate the overall survival of patients with newly diagnosed GBM when treated with TSC administered with standard of care. Secondary objectives of the study are to evaluate progression-free survival at six months and seven months by magnetic resonance imaging, assessment using Response Assessment in Neuro-Oncology criteria.   The trial will incorporate an innovative use of Positron Emission Tomography (“PET”) imaging to obtain an early read on TSC’s effects by directly evaluating the effects of TSC on tumor hypoxia, with initial data readouts from the dose-escalation phase of the study expected to be available within one year of the first patient being dosed. 

Financial Updates

Research and development expenses in the third quarter of 2022 were $0.8 million, compared to $2.1 million in the prior year period. This decrease was attributable to the timing of clinical trials and drug manufacturing, as well as a vendor-related refund.

General and administrative expenses were $2.1 million during the third quarter of 2022 versus $1.9 million in the comparable quarter last year. The increase primarily reflects a rise in outside services related to the ongoing business development activities.

As of September 30, 2022, Diffusion had $25.9 million in cash, cash equivalents, and marketable securities, which the Company currently expects will enable it to fund its operating expenses and capital expenditure requirements into the first quarter of 2024, without giving effect to the outcome and timing of the Company’s ongoing strategic review process.
