Diffusion Pharmaceuticals Announces Publication of RES-529 Review Article in Anti-Cancer Drugs

CHARLOTTESVILLE, Va., March 15, 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 the online publication of a reviewed article on RES-529 ahead of print in Anti-Cancer Drugs.  

Diffusion Pharmaceuticals recently acquired RES-529, a novel PI3K/AKT/mTOR pathway inhibitor that targets both mTORC1 and mTORC2 through mTOR complex dissociation, from RestorGenex Corporation at the closing of its reverse merger on January 8, 2016. RES-529 is being developed for oncology and ophthalmology with a primary focus in the treatment of glioblastoma multiforme (GBM). Orphan drug designation has been granted by the FDA for this indication.

The article entitled “RES-529: a PI3K/AKT/mTOR pathway inhibitor that dissociates the mTORC1 and mTORC2 complexes,” reviews the potential of RES-529 to inhibit tumorigenesis in glioblastoma, prostate cancer, and breast cancer. RES-529 treatment has been shown to be effective in preclinical models of glioblastoma as well as synergistic with radiation therapy in these models.  In preclinical models of prostate cancer, RES-529 has been shown to be synergistic with all three common modalities of treatment: radiation therapy, chemotherapy, and hormonal therapy. The article was authored by Mark Weinberg, MD, MBA, who was previously Senior VP of Clinical Development at RestorGenex.

David Kalergis, Chairman and Chief Executive Officer of Diffusion Pharmaceuticals, said, “The acquisition of RES-529 has strengthened our oncology pipeline. Concurrent with our primary focus of advancing our lead candidate, trans sodium crocetinate (TSC), into a Phase III clinical program in GBM and a Phase II/III trial in pancreatic cancer, we are also assessing the future opportunities and plans for RES-529.”

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.  Diffusion is developing its lead drug, trans sodium crocetinate (TSC), for use in the many cancer types in which tumor hypoxia (oxygen deprivation) 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.  TSC has potential application in other indications involving hypoxia, such as stroke and neurodegenerative diseases.

A Phase II clinical program, completed in the second quarter of 2015, evaluated 59 patients with newly diagnosed glioblastoma multiforme (GBM).  The 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 III trial in newly diagnosed GBM.  Additional planned studies include a Phase II/III trial in pancreatic cancer and a Phase II/III study in brain metastases.  Due to its novel mechanism of action, TSC safely re-oxygenates a range of tumor types. Its therapeutic potential is not limited to specific tumors, thereby making it potentially useful to improve current standard-of-care treatments of many life-threatening cancers.
