The Lancet Publishes SELECT Study Evaluating Efficacy and Safety of Biogen Idec, Inc. (Massachusetts) Daclizumab HYP in Multiple Sclerosis

WESTON, Mass.--(BUSINESS WIRE)--Today Biogen Idec (NASDAQ: BIIB) announced that results from the daclizumab high-yield process (DAC HYP) SELECT clinical trial have been published as an online article in The Lancet. SELECT was a Phase 2b study designed to determine the efficacy and safety of DAC HYP in patients with relapsing-remitting multiple sclerosis (RRMS). Published results demonstrate that both 150 mg and 300 mg subcutaneous injections of DAC HYP, administered once every four weeks, met the study’s primary endpoint by significantly reducing annualized relapse rate (ARR) by 54 percent (p<0.0001) and 50 percent (p=0.0002), respectively, compared to placebo at one year. In addition, results demonstrated that DAC HYP reduced multiple sclerosis (MS) brain lesions compared to placebo.
