Broad patent coverage for both composition of matter & specific receptor ligands for the treatment of erectile dysfunction

PETACH TIKVA, Israel, Nov. 9, 2016 /PRNewswire/ -- Can-Fite BioPharma Ltd. (NYSE MKT: CANF) (TASE: CFBI), a biotechnology company with a pipeline of proprietary small molecule drugs being developed to treat inflammatory and liver diseases, cancer, and sexual dysfunction, today announced it has received a Notice of Allowance from the U.S. Patent and Trademark Office for its patent application covering A3 adenosine receptor ligands for use in the treatment of erectile dysfunction. The patent addresses methods for treating erectile dysfunction with different A3 adenosine receptor (A3AR) ligands including Can-Fite's erectile dysfunction drug candidate, CF602. This marks Can-Fite's second notice of allowance in the U.S. for ligands which bind to the A3AR target. The prior patent, issued in February, addresses composition of matter for allosteric compounds. Can-Fite's CF602, an allosteric compound at the A3AR demonstrated effects on erection superior to that demonstrated by sildenafil (Viagra®) in diabetic animal studies. CF602 has a mechanism of action similar to sildenafil.

"With this notice of allowance, we believe we now have a broad spectrum of IP coverage which protects a broad spectrum of A3AR ligands in the treatment of erectile dysfunction. Based on this coverage, we intend to investigate additional compounds to optimize potential efficacy and safety for this indication," stated Can-Fite CEO Dr. Pnina Fishman

GlobalData estimates the value of the erectile dysfunction therapeutic market to be approximately $2.6 billion by 2018 with few drugs on the market which include Viagra, Cialis and Levitra. According to the American Diabetes Association, approximately 30 million Americans have diabetes mellitus in the U.S. and 35-75% of men with diabetes mellitus suffer from erectile dysfunction.

About CF602 

CF602 is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). A3AR is highly expressed in diseased cells whereas low expression is found in normal cells. This differential effect accounts for the excellent safety profile of the drug. Studies have shown treatment with CF602 results in statistically significant full recovery from erectile dysfunction after one single dose treatment in a pre-clinical diabetic model. The drug's mechanism of action includes efficacy in increasing penile intracavernous pressure (ICP) and restoration of impaired vascular endothelial growth factor.
