Conditions multiple sclerosis, relapsing-remitting, multiple sclerosis
Treatment dimethyl fumarate
Phase phase 3
Sponsor Biogen
Start date August 2015
End date March 2019
Trial size 218 participants
Trial identifier NCT02525874, 109MS310, 2015-001973-42


The primary objective of the study is to evaluate the effect of BG00012 on lymphocyte subset counts during the first year of treatment in subjects with relapsing-remitting multiple sclerosis (RRMS). A secondary objective is to evaluate the pharmacodynamic effect on absolute lymphocyte counts (ALCs) and immunoglobulins (Igs) during the first year of treatment.
