Phase II Study of Teriflunomide as Adjunctive Therapy to Interferon-beta in Subjects With Multiple Sclerosis

• Status: Completed
• Trial end date: 2009-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objective was to estimate the tolerability and safety of 2 doses of teriflunomide administered once daily for 24 weeks, compared with placebo, in patients with multiple sclerosis [MS] with relapses who were on a stable dose of interferon-β [IFN-β].

Secondary objectives were:

• to estimate the effects of the 2 doses of teriflunomide, compared to placebo, in combination with a stable dose of IFN-β on Magnetic Resonance Imaging [MRI] parameters, relapse rate and patient-reported fatigue;

• to perform pharmacokinetic analyses of the 2 doses of teriflunomide in combination with a stable dose of IFN-β.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sanofi
• Treatments: Interferon beta-1b; Interferon-beta; Interferons; Teriflunomide
