Can-Fite Expands Namodenoson anti-Obesity Franchise with Israeli Patent Allowance

Strengthens global IP and supports strategic positioning in the rapidly growing metabolic therapeutics market

Ramat Gan, Israel, March 17, 2026 (GLOBE NEWSWIRE) -- Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE:CANF), a clinical-stage biotechnology company developing a pipeline of proprietary small molecule drugs targeting oncological and inflammatory diseases, today announced that the Israeli Patent Office has allowed its patent application No. 284463, titled “An A3 Adenosine Receptor Ligand for Use for Achieving a Fat Loss Effect.” The allowed patent covers the use of A3 adenosine receptor (A3AR) agonists, including the Company’s lead drug candidate Namodenoson, for inducing fat loss and treating obesity and related metabolic disorders.

This allowance represents a key addition to Can-Fite’s expanding global intellectual property portfolio around Namodenoson’s anti-obesity activity and follows similar patent advancements in other major jurisdictions including the US, Canada and Australia, strengthening the Company’s worldwide protection strategy. Recently the technology granted scientific recognition upon coming up with a breakthrough publication of peer-reviewed study in the International Journal of Obesity, demonstrating the anti-obesity effect of namodenoson (https://rdcu.be/e37sf ).

The global obesity therapeutics market is experiencing rapid growth, driven by increasing prevalence and the success of GLP-1 receptor agonists. However, current treatments are often associated with limitations including gastrointestinal side effects and high cost. Namodenoson, a highly selective A3AR agonist, offers a differentiated mechanism of action, targeting key pathways involved in adipogenesis, inflammation, and metabolic regulation. Preclinical and clinical studies have demonstrated its potential to reduce fat accumulation and improve metabolic profiles, positioning it as a promising candidate in the expanding obesity treatment landscape.

“With the allowance of this patent in Israel, we continue to build and strengthen our intellectual property portfolio around Namodenoson’s anti-obesity activity,” said Dr. Pnina Fishman, Chairperson and Chief Scientific Officer of Can-Fite. “Given the significant unmet need and rapid growth of the obesity market, we believe Namodenoson’s unique mechanism and established safety profile position it as an attractive candidate for development and potential partnering opportunities.”

The global obesity treatment market is projected to reach $60.5 billion by 2030, growing at a compound annual growth rate (CAGR) of approximately 22%, driven by increasing disease prevalence and demand for safe, effective oral therapies.

About Namodenoson

Namodenoson is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). Namodenoson is currently being evaluated in a pivotal Phase III trial for advanced liver cancer, a Phase IIb trial for the treatment of Metabolic Dysfunction-associated Steatohepatitis (MASH), and in a Phase IIa study in pancreatic cancer. A3AR is highly expressed in diseased cells whereas low expression is found in normal cells. This differential expression may be one of the important factors that accounts for the excellent safety profile of the drug.
