Diffusion Pharmaceuticals Doses First Two Patients with TSC in COVID-19 Clinical Trial
CHARLOTTESVILLE, Va., Sept. 10, 2020 (GLOBE NEWSWIRE) -- Diffusion Pharmaceuticals Inc. (NASDAQ: DFFN) (“Diffusion” or the “Company”) today announced dosing of the first two patients in the Company’s open-label Phase 1b lead-in trial of its novel, oxygen-enhancing therapeutic, trans sodium crocetinate (“TSC”), in 24 hospitalized COVID-19 patients. In addition to evaluating the safety and tolerability of TSC, this trial will collect preliminary data on TSC’s effects on arterial blood oxygenation. The Company believes these pharmacodynamic data will provide proof of concept for TSC in hypoxemic patients, and these data will be used to guide design of the planned follow-on efficacy study.
The Phase 1b study is being conducted at the Romanian National Institute of Infectious Diseases. The planned follow-on efficacy trial will be a randomized, placebo-controlled safety and efficacy study of TSC in hospitalized COVID-19 patients that will be conducted in the United States and Europe after consultation with, and approval from, local regulatory authorities.
“Dosing TSC in oxygen-deprived, hospitalized COVID-19 patients is an important milestone for Diffusion,” said Robert Cobuzzi, chief executive officer of Diffusion. “We anticipate learning a lot about TSC’s effects on blood oxygen levels in COVID-19 patients, and we’re excited about the potential to incorporate the knowledge gained from this study into the broader TSC development program.”
About TSC and COVID-19
Patients with COVID-19 respiratory tract infections often present with significantly impaired oxygen levels. Diffusion and its affiliated researchers believe the oxygen-enhancing mechanism of action of TSC could benefit such patients. Preclinical data indicate TSC increases oxygen availability and provides a functional benefit in animal models of acute lung injury and hemorrhagic shock. Clinical data from more than 150 patients receiving TSC for other indications demonstrate that the drug has an acceptable safety profile in both healthy and critically ill 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, TSC, was originally developed in conjunction with the United States (“U.S.”) Office of Naval Research, which was seeking a way to treat multiple organ failure and its resulting mortality caused by low oxygen levels from blood loss on the battlefield. Evolutions in research have led to Diffusion’s ocus today on addressing some of medicine’s most intractable and difficult-to-treat diseases, including multiple organ failure from respiratory distress, stroke and glioblastoma multiforme (“GBM”) brain cancer. In each of these diseases, lack of available oxygen presents a significant obstacle for medical providers and is the target for TSC’s novel mechanism. The Company is currently partnering with U.S. and European institutions on an expedited research program to develop TSC as a treatment for the low oxygen levels and associated multiple organ failure in COVID-19 patients.
Preclinical data support the potential for TSC as a treatment for other conditions where low oxygen availability plays an important role, such as myocardial infarction, peripheral artery disease and neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease. In addition to the development of TSC, 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.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Uncertainties and risks may cause the Diffusion’s actual results to be materially different than those expressed in or implied by such forward-looking statements. Particular uncertainties and risks include: the timing of the enrolment and completion of the Phase 1b study, the pharmacodynamic data providing proof of concept for TSC in hypoxemic patients, and the use of these data to guide design of the planned follow-on efficacy study; the uncertainty as to whether the protocol for the planned United States and European follow-on efficacy study referenced above will be ultimately acceptable to the U.S. Food and Drug Administration (“FDA”) and appropriate European regulators, that the FDA or European regulators will not require significant changes that might take significant time to implement, if at all, that any such required changes will be financially feasible or that administrative or other delays may arise; the uncertainty as to whether and when the FDA or European regulators might provide any additional guidance with respect to our study protocol or when the program might be able to commence, if at all; the uncertainty that as of yet the FDA has not approved a trial evaluating TSC for the treatment of ARDS, or if approved, such a trial may entail significant additional time, effort and expense, particularly in light of the difficulty of doing business during the COVID-19 pandemic; Diffusion’s ability to maintain its Nasdaq listing, market conditions, the difficulty of developing pharmaceutical products, obtaining regulatory and other approvals and achieving market acceptance; general business and economic conditions; the sufficiency of the company’s cash, the company's need for and ability to obtain additional financing or partnering arrangements; and the various risk factors (many of which are beyond Diffusion’s control) as described under the heading “Risk Factors” in Diffusion’s filings with the United States Securities and Exchange Commission.
