CHARLOTTESVILLE, Va., June 08, 2016 (GLOBE NEWSWIRE) — Diffusion Pharmaceuticals Inc. (OTCQX:DFFN), a clinical stage biotechnology company focused on the development of novel small molecule therapeutics for cancer, today announced that a U.S. patent application, entitled “Bipolar Trans Carotenoid Salts and Their Uses,” was allowed by the United States Patent and Trademark Office.
This application, which is expected to issue in the second half of 2016, expands coverage of the therapeutic use of trans sodium crocetinate (TSC) and other related compounds to five hypoxia-related conditions including congestive heart failure, chronic renal failure, acute lung injury (ALI), chronic obstructive pulmonary disease (COPD), and respiratory distress syndrome (RDS). Diffusion’s patent estate currently includes the use of TSC in oncology, stroke, and neurodegenerative disease (such as Alzheimer’s disease) indications.
David Kalergis, Chairman and Chief Executive Officer of Diffusion, remarked, “The allowance of this patent application is a significant milestone for Diffusion as it expands our patent estate and underscores the potential of TSC to serve as a primary therapeutic agent in many conditions involving hypoxia. Over the long term, we look forward to evaluating development opportunities across the five new indications covered by the patent. We are currently focused on expanding the clinical development pipeline for TSC from treatment for glioblastoma (GBM) to include treatment for pancreatic cancer.”
About Diffusion Pharmaceuticals
Diffusion Pharmaceuticals is a clinical stage biotechnology company focused on extending the life expectancy of cancer patients by improving the effectiveness of current standard-of-care treatments including radiation therapy and chemotherapy. The Diffusion technology is a paradigm shift in the approach to the treatment of cancer and other diseases involving hypoxia, or oxygen deprivation, in that it facilitates the diffusion of oxygen to the hypoxic tissues. Diffusion is developing its lead drug, trans sodium crocetinate (TSC), for use in the many cancer types in which tumor hypoxia is known to diminish the effectiveness of current treatments. TSC targets the cancer’s hypoxic micro-environment, re-oxygenating treatment-resistant tissue and making the cancer cells more vulnerable to the therapeutic effects of treatments such as radiation therapy and chemotherapy, without the apparent addition of any serious side effects.
A Phase 2 clinical program, completed in the second quarter of 2015, evaluated 59 patients with newly diagnosed glioblastoma multiforme (GBM). This open label, historically controlled study demonstrated a favorable safety and efficacy profile for TSC combined with standard of care. The U.S. Food and Drug Administration has agreed upon the design of a Phase 3 trial in newly diagnosed GBM. Additional planned studies, subject to receipt of necessary financing, include the Phase 2 trial in pancreatic cancer and a study in brain metastases. Due to its novel mechanism of action, TSC has safely re-oxygenated a range of tumor types in our preclinical and clinical studies. The Company believes its therapeutic potential is not limited to specific tumors, thereby making it potentially useful to improve standard-of-care treatments of other life-threatening cancers.
