  Purpose
This study consisted of a two year dose blinded phase during which patients received one of five doses of siponimod (10, 2, 1.25, 0.5 or 0.25mg) following which patients were switched to open label treatment with siponimod 2mg for approximately a further 3 years. It will provide data on long term safety, tolerability and efficacy of siponimod in the RRMS patient population

Condition Intervention Phase
Relapsing Remitting Multiple Sclerosis Drug: BAF312 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
This extension study was originally set up as a 2 year dose-blinded extension study to maintain blinding of ongoing Core study. Study was later amended to include a subsequent Open-Label treatment phase after Core study was unblinded. During the Dose-Blinded phase of the extension study patients received the same dose from the Core study. Patients who received placebo in Period 1 during the Core Study were equally randomized to 1 of the 3 active doses of siponimod used during Period 1 (0.5, 2.0, or 10 mg) and patients who received placebo in Period 2 were equally randomized to 1 of the 2 active doses of siponimod used during Period 2 (0.25 mg or 1.25 mg).
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:
Masking continued during the double blind period of extension only.
Primary Purpose: Treatment
Official Title: A Dose Blinded Extension Study to the CBAF312A2201 Study to Evaluate Long-term Safety, Tolerability and Efficacy of BAF312 Given Orally Once Daily in Patients With Relapsing-remitting Multiple Sclerosis

Primary Outcome Measures:
  • Total Number of Adverse Events During Evaluation of Long Term Safety and Tolerability of BAF312A in Extension Study. [ Time Frame: Baseline up to approximately 5 years ]
    Refer to adverse events for complete listing of serious adverse events and other adverse events. Adverse events of interest were presented in separate tables. There were no reports of macular edema.

  • Number of Participants With Cardiac Conduction Abnormalities During the Titration Phase of the Study (Without Washout) [ Time Frame: Baseline Extension up to day 10 ]
    Number of patients with abnormal ECG conduction findings during dose-blinded titration at any visit post-dose, by type of abnormality and treatment (Extension Set). Number analyzed represent participants who had ECG results. Washout was defined as not being on treatment drug between Core and Extension for >7 days. Abbreviation: Con=conduction, IVCD=intraventricular conduction defect , WPW=Wolff-Parkinson-White syndrome

  • Number of Participants With Cardiac Conduction-IVCD Abnormality During the Titration Phase of the Study (With Washout) [ Time Frame: Baseline Extension up to day 10 ]
    Number of patients with abnormal ECG conduction findings during dose-blinded titration at any visit post-dose, by type of abnormality and treatment (Extension Set). Number analyzed represent participants who had ECG results. Washout was defined as not being on treatment drug between Core and Extension for >7 days. Abbreviations: washout = WO, Con=conduction

  • Number of Participants With Changes in Blood Pressure for Overall Extension Study. (Extension Analysis Set) [ Time Frame: Baseline Extension up to approximately 5 years ]
    Sitting blood pressure was measured in triplicate. The categories of notably low and high values and changes are presented for systolic (SBP) and diastolic (DBP). Multiple occurrences for a patient are counted as one occurrence in this table.

  • Number of Participants With Viral Infections of Interest Greater or Equal to 5% in Any Dose Group (Extension Set) [ Time Frame: Baseline Extension up to approximately 5 years ]

    Most infections were clinical diagnoses and were not confirmed by microbiology / virologic investigations. A patient with multiple occurrences of an infection for a preferred term is counted only once in each specific category.

    Events identified as infections by the Investigator and defined as an AE with onset on or after the first dose of Extension Study drug up to and including 30 days after the date of the last dose


  • Number of Participants With Dermatologic Alterations - Basal Cell Carcinoma (Extension Set) [ Time Frame: Baseline Extension up to approximately 5 years ]

Secondary Outcome Measures:
  • Number of Relapses in One Year - Annualized Relapse Rates for Overall Extension Study (ARR) (Extension Set) [ Time Frame: Baseline extension up to approximately 5 years ]

    Group level ARR (raw) is calculated as the total number of relapses for all the patients in the treatment group divided by the total number of days on study for all patients in the group and multiplied by 365.25 to obtain the annual rate.

    Model estimates are based on a negative binomial regression model, adjusted for treatment group, age, baseline EDSS, baseline number of Gd-enhanced T1 lesions and number of relapses in previous 2 years as covariates, with log(time on study in years) as the offset variable, using the log link.


  • Percentage of Participants Free of Magnetic Resonance Imaging (MRI) Identified Disease Activity at Any Scan During Extension Study (Extension Set) [ Time Frame: Baseline Extension up to approximately 5 years ]

    Free of MRI disease activity is defined as free of Gadolinium enhanced T1 lesions at any scan; free of new or enlarging T2 lesions at any scan: free of both gadolinium enhanced T1 lesions and new or enlarging T2 lesions at any scan. Number of patients analyzed = patients with at least one MRI scan during the specified time period. New lesions at a specific visit are assessed relative to the previous scheduled visit scan.

    No imputation of missing scans is performed. As a result missing scans can lead to an overestimation of the proportion of patients free of a specific MRI activity.


  • Percentage of Participants Free of Confirmed Disability Progression in Extension Study (Extension Set) [ Time Frame: Baseline Extension up to approximately 5 years ]
    Six-month disability progression was defined relative to extension baseline EDSS score: 1.5 point increase in patients with baseline EDSS score of 0, 1.0 increase in patients with baseline EDSS score of between 0.5 to 5.0, inclusive and 0.5 increase in patients with baseline EDSS score of ≥ 5.5. The criteria for 6-month disability progression included detection of onset of progression and confirmation of progression for a period of at least 6 months.
