Tysabri: A Drug Snatched from the "Jaws of Defeat"
You gotta give Biogen/IDEC and Elan credit for winning regulatory approval for a product that was previously pulled from the market because of serious and potentially life-threatening side effects. On Monday, the US Food and Drug Administration granted regulatory approval for Tysabri as a treatment for patients with severe Crohn’s disease who do not respond to more conventional biotechnology treatments like Humira (Abbott Laboratories) and Remicade (Johnson & Johnson). About 500,000 patients in the US suffer from Crohn’s disease (an autoimmune disease) and usually causes diarrhea, fever and severe intestinal inflammation and bleeding. Currently, there is no known cure for the disease.
As many of you may recall, Tysabri, a treatment for multiple sclerosis, was temporary pulled from the market in 2005 after three patients treated with the drug developed a rare and sometimes fatal nervous disorder called multifocal leukoencephalopathy (MFL). FDA allowed the drug back on to the market in 2006 but only under a restricted distribution program. Tysabri is used by more than 12,000 Americans with multiple sclerosis . Since its reintroduction, there have been no new reports of MFL or other serious side effects. Because of its past safety record, patients with Crohn’s disease who use the drug must also enroll in a distribution program similar to the one required for MS patients treated with Tysabri.
The approval of Tysabri for a new therapeutic indication may make Biogen/IDEC a more attractive takeover candidate. As many of you may know, Biogen/IDEC put itself up for sale about 3 months ago and was unable to find a buyer.
Until next time….

The buzz and promise of biotechnology is the likely cause of the buying frenzy that big pharma has been on lately. Word on the street is that biotechnology products are innovative, have a higher return on investment (ROI) and are generally perceived to be “better” than conventional small molecule drugs. I agree that biotechnology products are certainly innovative and the gargantuan ROIs are titillating. But, are biotechnology products always safer and more efficacious than extant small molecule drugs? According to a recent study–maybe not!
