PG - 2055217315618687 LID - 10.1177/2055217315618687 [doi] LID - 2055217315618687 AB - BACKGROUND: Teriflunomide is a once-daily oral immunomodulator for the treatment of relapsing-remitting MS. OBJECTIVE: To evaluate the safety and tolerability of teriflunomide as add-on therapy to a stable dose of glatiramer acetate (GA) in patients with relapsing forms of MS (RMS). METHODS: Phase II, randomized, double-blind, add-on, placebo-controlled study. The primary objective was to assess safety and tolerability; secondary objectives were to evaluate effects of treatment on disease activity assessed by MRI and relapse. RESULTS: Patients with RMS on GA (N = 123) were randomized 1:1:1 to receive teriflunomide 14 mg (n = 40), 7 mg (n = 42), or placebo (n = 41) for 24 weeks; 96 patients entered the 24-week extension, remaining on original treatment allocation. Teriflunomide was well tolerated over 48 weeks. The frequency of adverse events (AEs) was low across all groups; 5 (12.2%), 3 (7.1%), and 2 (5.0%) patients in the 14 mg, 7 mg, and placebo groups, respectively, discontinued treatment due to AEs. Teriflunomide reduced the number of T1-Gd lesions vs placebo (14 mg: 46.6% relative reduction, p = 0.1931; 7 mg: 64.0%: relative reduction, p = 0.0306). CONCLUSIONS: Teriflunomide added to stable-dose GA had acceptable safety and tolerability, and reduced some MRI markers of disease activity compared with GA alone.
