Tysabri (also known as Natalizumab) is a medication that is used to treat Multiple Sclerosis (MS). Tysabri helps decrease the number of symptoms such as muscle spasms or weakness. It is prescribed to treat patients with relapsing forms of MS in order to reduce the frequency of flare-ups. Tysabri is also approved by the U.S. Food and Drug Administration (FDA) for the treatment of Crohn’s disease, a chronic, progressive disease marked by inflammation of the bowel. Tysabri may be prescribed for Crohn’s patients who have been unsuccessful with other treatments, Remicade by Johnson & Johnson and Humira by Abbott Laboratories, for example.

Tysabri is manufactured by a Cambridge, MA company, Biogen Idec Inc. and distributed by the Elan Corporation of Ireland. The drug was approved by the Food and Drug Administration (FDA) on November 23, 2004. In February 2005 the manufacturer withdrew the drug from the market after three patients involved in the drug’s clinical trials developed PML. In March 2006 the FDA made the decision to allow the use of Tysabri in appropriate MS patients. In response, Biogen submitted a Risk Minimization Plan to help ensure safe use of the product. In order to get Tysabri, patients must talk with their doctor and understand the risks and benefits of the drug and agree to all the instructions in the Risk Management Plan.

The plan rules include:

Tysabri can only be prescribed by doctors who register with the program.
Tysabri will only be administrated to patients who are enrolled in the program.
Before taking Tysabri, patients must get an MRI to help differentiate future MS symptoms from PML.
Patients on Tysabri are to be evaluated at 3 months, 6 months and following. Information from the evaluations will be reported regularly to Biogen Idec Inc

Jaundice
Fatigue
