Tysabri Liver Damage & Melanoma Risks

The manufacturers of Tysabri, Biogen Idec Inc. and Elan Corp. plc warned about reports of liver toxicity in patients treated with the drug. The companies sent a letter to healthcare professionals (dear doctor letter), notifying them about the potential risks. This warning came just a couple of weeks after a letter in the New England Journal of Medicine cautioned doctors about two aggressive cases of malignant melanoma that occurred shortly after Tysabri was administered.

Tysabri is the brand name for natalizumab, a monoclonal antibody that is approved for the treatment of Multiple Sclerosis (MS) and Crohn’s disease. Tysabri was first approved by the FDA in November 2004, but was removed from the market just three months later after several patients were diagnosed with a rare, often fatal opportunistic brain infection called progressive multifocal leukoencephalopathy (PML). The FDA allowed Tysabri back on the market in June 2006 for the treatment of Multiple Sclerosis with revised warnings and strict requirements for close monitoring of patients receiving the drug. Earlier this year, the FDA approved Tysabri for the treatment of Crohn’s disease.
