Tysabri is the first humanized monoclonal antibody approved for the treatment of MS. The drug works by preventing the cells that cause inflammation and damage to nerve fibers and their insulation (myelin) from migrating from the bloodstream into the brain. Based on partial results from a two-year study, Tysabri won FDA approval. Tysabri, which Biogen had marketed in conjunction with Ireland's Elan Pharmaceuticals, had been heralded as a new hope for multiple sclerosis patients. About 5,000 patients have received intravenous infusions of Tysabri since the drug's approval in November. Subsequent to the drugs’ approval, it has been reported that patients who had been treated with Tysabri in trials had developed a rare and frequently fatal brain disorder called progressive multifocal leukoencephalopathy (PML). More information from the FDA on the Tysabri suspension can be found at: public health advisory and questions and answers: www.fda.gov/cder/drug/infopage/natalizumab.

Biogen-IDEC enjoyed $3 million in Tysabri sales for in the final weeks of 2004 and had excitedly projected annual sales to reach $1.5 billion by 2007. Unfortunately, the prospects of even more profitability for the pharmaceutical giants were dampened when reports of serious events associated with the drug surfaced.

Annually, an estimated 1.5 million (or more than 4,000 people per day) people are admitted to hospitals as a result of adverse drug reactions. These disturbing numbers have led one former FDA expert to advise “...don’t try a drug until it’s been on the market at least 2 to 5 years - whoever takes a newly approved drug is a non-consenting guinea pig...”.

Please consult your physician before discontinuing any medication.
