  Purpose
This study is an extension to the study AC-058B201 and will investigate the long-term safety, tolerability and efficacy of ponesimod in patients with relapsing-remitting multiple sclerosis.

Condition Intervention Phase
Multiple Sclerosis
Drug: Ponesimod 10 mg
Drug: Ponesimod 20 mg
Drug: Ponesimod 40 mg
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Multicenter, Randomized, Double-blind, Parallel-group Extension to Study AC-058B201 to Investigate the Long-term Safety, Tolerability, and Efficacy of Three Doses of Ponesimod, an Oral S1P1 Receptor Agonist, in Patients With Relapsing-remitting Multiple Sclerosis

Primary Outcome Measures:
  • Annualized confirmed relapse rate [ Time Frame: 240 weeks ]
    IMPORTANT NOTE: Only exploratory analyses will be performed.

  • Time to first confirmed relapse [ Time Frame: 240 weeks ]
    IMPORTANT NOTE: Only exploratory analyses will be performed.

  • Time to 3 month confirmed disability progression up to end of the study [ Time Frame: Estimated period of time over which the event is assessed: 3 months. The time to event is defined as the time from initiation of study treatment until the first EDSS assessment meeting the criteria for disability progression. ]
    IMPORTANT NOTE: Only exploratory analyses will be performed. Disability progression is defined as an increase of at least one full point in the Expanded Disability Status Scale (EDSS) score (or 1.5 points if the baseline EDSS was 0, or 0.5 points if the baseline EDSS was equal or greater than 5.5) with or without relapse, confirmed at the next scheduled EDSS assessment at least 12 weeks later (or if missing, at the next available scheduled EDSS assessment).

  • Time to 6 month confirmed disability progression up to end of the study [ Time Frame: Estimated period of time over which the event is assessed: 6 months. The time to event is defined as the time from initiation of study treatment until the first EDSS assessment meeting the criteria for disability progression. ]
    IMPORTANT NOTE: Only exploratory analyses will be performed. Disability progression is defined as an increase of at least one full point in the Expanded Disability Status Scale (EDSS) score (or 1.5 points if the baseline EDSS was 0, or 0.5 points if the baseline EDSS was equal or greater than 5.5) with or without relapse, confirmed at the next scheduled EDSS assessment at least 12 weeks later (or if missing, at the next available scheduled EDSS assessment).


Other Outcome Measures:
  • (Serious) Adverse Events [ Time Frame: Through study completion, for approx. 10 years: during Treatment Period (incl. Transition), i.e. study drug administration plus 7 days, and during the Follow up, i.e. from 8 until 30 days (Period 1) or until 90 days (Period 2) after study drug discontin. ]

Enrollment: 353
Study Start Date: May 2010
Estimated Study Completion Date: January 2022
Estimated Primary Completion Date: December 2021 (Final data collection date for primary outcome measure)
