Diffusion Pharmaceuticals Announces Stock Ticker Symbol Change to DFFN

CHARLOTTESVILLE, Va., Jan. 25, 2016 -- Diffusion Pharmaceuticals Inc., a clinical stage biotechnology company focused on the development of novel small molecule therapeutics for cancer, today announced that FINRA has approved a change in the Company’s stock symbol. Effective today, the Company’s common shares will commence trading on the OTC Markets under the trading symbol “DFFN” (OTCQX:DFFN). The previous trading symbol was “RESX” (OTCQX:RESX).

David Kalergis, President and CEO of the Company, said, “We are pleased to begin trading under the new DFFN symbol as this marks one of the final steps associated with the merger. Diffusion continues to develop its lead drug, trans sodium crocetinate (TSC), and is on track to commence a Phase III trial in newly diagnosed glioblastoma (GBM) and a Phase II/III trial in pancreatic cancer in 2016.”

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. This trial has been the basis for discussions with the U.S. Food and Drug Administration. A Phase III program in newly diagnosed GBM is expected to commence in 2016. Additional planned studies include a Phase II/III trial in pancreatic cancer, also expected to commence in 2016. A Phase II/III study in brain metastases is also being planned. TSC’s novel mechanism safely re-oxygenates a range of tumor types, so 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.
