Medivir announces the first cancer project derived from its in-house nucleotide platform

Stockholm, Sweden — Medivir AB (Nasdaq Stockholm: MVIR) today announces a new discovery project for a cancer indication, a liver targeted nucleotide prodrug for the treatment of hepatocellular carcinoma (HCC). The project is based on the company’s expertise in nucleoside and nucleotide science and is the first cancer project to emerge from its in-house discovery efforts in oncology that were announced in 2014.

“Our HCC nucleotide project has made very rapid progress after its initiation last year” said Richard Bethell, EVP Discovery Research. “We have identified molecules with excellent activity against a range of HCC cell lines and with the required distribution properties to enable them to be delivered selectively to the liver. Preclinical testing of these molecules in relevant models of HCC will begin early in the third quarter.”

Hepatocellular carcinoma is the most common cancer of the liver. Liver cancer is the second leading cause of cancer-related death world-wide, and one of the fastest growing cancers in the US based on incidence and mortality.
