Bayer and Onyx seek European approval for liver cancer drug

Nexavar is currently approved in more than 50 countries for the treatment of advanced kidney cancer. The companies plan to file a supplemental new drug application with the FDA for Nexavar in the treatment of liver cancer this summer.

The MAA submission is based on positive data from a phase III trial which demonstrated that Nexavar extended overall survival by 44% in patients with hepatocellular carcinoma (HCC) versus placebo.

There were no significant differences in serious adverse event rates between the Nexavar and placebo-treated groups, with the most commonly observed serious adverse events in patients receiving Nexavar being diarrhea and hand-foot skin reaction.

According to the companies, there are currently no EMEA-approved drug therapies that significantly extend survival of liver cancer patients.

HCC, the most common form of liver cancer, is responsible for about 90% of the primary malignant liver tumors in adults, and is the fifth most common cancer in the world.
