On June 4, 2020 Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE:CFBI), a biotechnology company advancing a pipeline of proprietary small molecule drugs that address inflammatory, cancer and liver diseases, reported it has successfully concluded a meeting with the Scientific Advice Working Party (SAWP) of the European Medicines Agency (EMA) regarding Phase III development of its drug candidate Namodenoson in the treatment of hepatocellular carcinoma (HCC), the most common form of liver cancer (Press release, Can-Fite BioPharma, JUN 4, 2020, View Source [SID1234560824]).

Namodenoson is Can-Fite’s adenosine A3 receptor (A3AR) agonist which has recently been shown to prolong median overall survival (OS) in a selected patient population with HCC in a Phase II clinical trial. Can-Fite sought scientific advice from the EMA to complement previous input from the U.S. Food and Drug Administration (FDA) in its recent End-of-Phase II meeting regarding plans for a Phase III registration trial of Namodenoson in patients with HCC and Child Pugh Class B7 (CPB7) cirrhosis. Having completed its meeting with the SAWP, Can-Fite now has sufficient regulatory input to conduct a registration trial in accordance with the requirements of both the U.S. and the European Union.
The planned trial, a randomized, double blind, placebo controlled trial, will enroll approximately 450 patients with HCC and underlying CPB7 cirrhosis at multiple centers worldwide. Patients will be randomized to oral treatment with either Namodenoson 25 mg or matching placebo given twice daily. The primary efficacy endpoint of the trial is overall survival (OS), based on the favorable OS response seen in the Phase II trial in patients with HCC and CPB7 cirrhosis. Other oncology trial efficacy outcomes, such as tumor radiographic response rates and median progression-free survival, as well as standard safety parameters, will be assessed.
"We appreciate the EMA’s advice which, combined with the input we received last October from the U.S. FDA along with recommendations from our academic key opinion leaders, gives us excellent guidance for conducting a successful Phase III clinical and registration program," stated Can-Fite CEO Dr. Pnina Fishman.
According to the American Cancer Society, liver cancer accounts for more than 700,000 deaths globally each year. HCC is commonly aggressive with poor survival rates. As new drugs that effectively and safely treat HCC are developed and approved, the market for HCC treatments is estimated by Delveinsight to reach $3.8 billion by 2027 for the G8 countries.
About Namodenoson
Namodenoson is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). Namodenoson is being evaluated as a second line treatment for hepatocellular carcinoma, with a recently completed Phase II trial and planned Phase III trial in this indication. The drug recently concluded a Phase II trial which successfully achieved efficacy and safety endpoints in the treatment for non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). 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.
