• CF602's unique mechanism of action enables potential treatment of diabetic patients and may offer an alternative to PDE5 (Viagra, Cialis, Levitra, and Stendra) non-responders accounting for 30-35% of the $3.6 billion ED market
• Patents granted in numerous healthcare markets including the U.S., Australia, and Japan

Can-Fite BioPharma Ltd. (NYSE:CANF) (TASE: CFBI), a biotechnology company advancing a pipeline of proprietary small molecule drugs that address inflammatory, cancer and liver diseases, today announced its study titled "A3 adenosine receptor allosteric modulator CF602 reverses erectile dysfunction in a diabetic rat model" was published in the peer-reviewed journal Andrologia.

A full erectile recovery was achieved following a single dose of CF602 with restored muscle collagen ratio and endothelial cell function. Can-Fite's CF602, an allosteric modulator of the A3 adenosine receptor (A3AR), applied topically or orally in a diabetic rat model, resulted in increased arterial blood flow and significant dose-dependent improvements in intracavernosal pressure (ICM), smooth muscle:collagen ratio, vascular endothelial growth factor and endothelial nitric oxide synthase.

While oral phosphodiesterase type 5 (PDE5) inhibitors are the current standard of care for erectile dysfunction (ED), with brands including Viagra, Cialis, Levitra, and Stendra, an estimated 30% to 35% of ED patients are non-responders, and these drugs can be contraindicated for people living with diabetes.

According to Zion Market Research, the global ED market was valued at $3.64 billion in 2021 and is projected to reach $5.94 billion by 2028.
