Biogen Announces Data from Phase 3 ADVANCE Study of PLEGRIDY Show Significant Clinical and MRI Improvements with

Biogen Idec BIIB announced new data analyses from year one of the two-year, pivotal, Phase 3 ADVANCE study of PLEGRIDYTM (peginterferon beta-1a). PLEGRIDY is an investigational subcutaneous injectable for relapsing forms of multiple sclerosis (RMS), in which interferon beta-1a is pegylated to prolong the molecule's exposure in the body and enable the study of a less frequent dosing schedule. Clinical and MRI data from the study demonstrated a reduction in relapses, disability progression and the number of MS lesions when compared to placebo, and further support the clinical efficacy profile of PLEGRIDY. These data will be presented this week at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in See full press release
