When Hillel Panitch, MD, decided last summer to accept an invitation to make a presentation on the status of multiple sclerosis (MS) clinical trials at the annual meeting of the American Society for NeuroTherapeutics (ASENT), he did not realize just how timely his presentation would be. "This turned out to be a little more topical than I thought it would be, because of the news over the last few days," he told attendees of the session on March 4 in Washington, DC. "The news," of course, was the withdrawal from the market of natalizumab (Tysabri, Elan Corporation/Biogen Idec), a newly approved drug for MS, and the discontinuation of clinical trials after 1 fatality and an occurrence of another serious disorder in one of the trials.
