Inclusion in FDA’s Coronavirus Treatment Acceleration Program significantly shortens regulatory review cycles
Simultaneous patient enrollment planned in both the U.S. and Eastern Europe to speed time to data readoutCHARLOTTESVILLE, Va., May 05, 2020 (GLOBE NEWSWIRE) — Diffusion Pharmaceuticals Inc. (NASDAQ: DFFN) (“Diffusion” or “the Company”), a cutting-edge biotechnology company developing new treatments for life-threatening medical conditions by improving the body’s ability to deliver oxygen to the areas where it is needed most, today announced that the U.S. Food and Drug Administration (FDA) will accelerate its review of the Company’s clinical development plan using trans sodium crocetinate (TSC) in COVID-19 patients displaying severe respiratory symptoms and low oxygen levels. Development of Acute Respiratory Distress Syndrome (ARDS) is common in patients hospitalized with COVID-19 due to lack of sufficient oxygen to vital organs as a consequence of impedance in the lungs. Diffusion believes that TSC’s novel oxygen-enhancing mechanism of action could provide an important new treatment option for this life-threatening condition.Under federal regulations, the FDA had up to 60 days from the Company’s April 24, 2020 submission to respond, but the FDA has announced its intention to significantly shorten review times for select COVID-19 submissions under its Coronavirus Treatment Acceleration Program (CTAP). Clinical trial preparations at multiple potential sites are continuing as the Company awaits the FDA’s expedited response.Diffusion’s COVID-19 program is a cooperative research effort with the University of Virginia Health System (UVA) and the Integrated Translational Research Institute of Virginia (iTHRIV). To aid in timely trial enrollment, Diffusion is in discussions with institutions located in areas of severe COVID-19 incidence, both in the U.S. and in Eastern Europe. Similar to the FDA CTAP, health authorities in certain Eastern European countries have implemented emergency policies to compress regulatory review cycles from months to just days. These policies could expedite partnering possibilities with one or more Eastern European national institutes currently treating hundreds of COVID-19 patients daily, with almost immediate study start up and shortened time to data.“This news of accelerated FDA review of the proposed clinical development plan for our lead compound TSC in a COVID-19 ARDS program is most welcome,” said David Kalergis, chief executive officer of Diffusion. “We continue to work with hospital and regulatory authorities in the U.S., and now also in Eastern Europe, to forge the fastest possible pathway to approval for TSC in the treatment of COVID-19 patients.”About Diffusion Pharmaceuticals Inc.Diffusion Pharmaceuticals Inc. is an innovative biotechnology company developing new treatments that improve the body’s ability to deliver oxygen to the areas where it is needed most, offering new hope for the treatment of life-threatening medical conditions. Diffusion’s lead drug trans sodium crocetinate (TSC) was originally developed in conjunction with the Office of Naval Research, which was seeking a way to treat multiple organ failure and its resulting mortality caused by the systemic hypoxemia from blood loss on the battlefield. Evolutions in research have led to Diffusion’s focus today: Fueling Life by taking on some of medicine’s most intractable and difficult-to-treat diseases, including multiple organ failure, stroke and glioblastoma multiforme (GBM) brain cancer. In each of these diseases, hypoxia – oxygen deprivation of essential tissue in the body – has proved to be a significant obstacle for medical providers and is the target for TSC’s novel mechanism.In July 2019 the Company reported favorable safety data in a 19-patient dose-escalation run-in study to its Phase 3 INTACT program, using TSC to target inoperable GBM. Further findings from the dose-escalation run-in study, released in December 2019, also showed possible signals of enhanced survival and patient performance. Diffusion’s in-ambulance PHAST-TSC trial for acute stroke began enrolling patients last year. Given the heightened responsibilities of the Company’s emergency medical services providers, enrollment in this trial is expected to be minimal until the COVID-19 pandemic abates. The Company is also currently partnering with the University of Virginia and iTHRIV in a research program to develop its novel small molecule TSC as a treatment for Acute Respiratory Distress Syndrome (ARDS) from COVID-19, specifically targeting the associated multiple organ failure.Preclinical data supports the potential for TSC as a treatment for other conditions where hypoxia plays a major role, such as myocardial infarction, peripheral artery disease, and neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease. In addition, RES-529, the Company’s PI3K/AKT/mTOR pathway inhibitor that dissociates the mTORC1 and mTORC2 complexes, is in preclinical testing for GBM.Diffusion is headquartered in Charlottesville, Virginia – a hub of advancement in the life science and biopharmaceutical industries – and is led by CEO David Kalergis, a 30-year industry veteran and company co-founder.Forward-Looking StatementsTo the extent any statements made in this news release deal with information that is not historical, these are forward-looking statements under the Private Securities Litigation Reform Act of 1995.
