VUMERITY Offers the Efficacy Demonstrated by dimethyl fumarate Across 2 Pivotal Trials1

The efficacy of VUMERITY is based upon bioavailability studies in patients with relapsing forms of multiple sclerosis and healthy subjects comparing oral dimethyl fumarate delayed-release capsules to VUMERITY delayed-release capsules. The clinical studies described below were conducted using dimethyl fumarate.

Study 1: A 2-year, randomized, double-blind, placebo-controlled study of 1234 patients with RRMS. The primary endpoint was proportion of patients relapsed.

Study 2: A 2-year, multicenter, randomized, double-blind, placebo-controlled study that also included an open-label comparator arm in 1417 patients with RRMS. The primary endpoint was annualized relapse rate.

*Disability progression was defined as at least a 1-point increase from baseline EDSS of ≥1.0, OR at least a 1.5-point increase for patients with baseline EDSS of 0 sustained for 12 weeks.
