Efficacy and Safety Study of Ozanimod (RPC1063) in Relapsing Multiple Sclerosis Patients

Phase 2
Completed
Conditions
Relapsing Multiple Sclerosis
Interventions
Drug: Placebo
Registration Number
NCT01628393
Lead Sponsor
Celgene
Brief Summary

This study is a two-part trial consisting of Part A (presented in this record) and Part B (see NCT02047734).

The primary objective in Part A of this study was to demonstrate the superior efficacy of ozanimod compared to placebo by showing a reduction in the cumulative number of total gadolinium-enhancing (GdE) lesions from Week 12 to Week 24 in patients with relapsing multiple sclerosis (RMS).

PlaceboPlaceboParticipants received placebo to ozanimod oral capsules daily for 24 weeks. Participants who completed the 24-week treatment period had the option to enter the blinded extension period and were randomized to receive ozanimod 0.5 mg or 1 mg weekly for 96 weeks.
Ozanimod 0.5 mgOzanimodParticipants received ozanimod 0.5 mg oral capsules daily for 24 weeks. Participants who completed the 24-week treatment period had the option to enter the blinded extension period and continue to receive ozanimod 0.5 mg weekly for another 96 weeks.

Primary Outcome Measures
NameTimeMethod
Total Number of Gadolinium-Enhancing (GdE) Lesions Assessed on Brain Magnetic Resonance Imaging (MRI) From Week 12 to Week 24From Week 12 to Week 24; MRI was performed at Weeks 12, 16, 20, and 24

The cumulative number of total GdE lesions on MRI from Week 12 to Week 24. MRI scans were assessed and scored by an independent MRI analysis center with no knowledge of treatment assignment or outcomes.

Secondary Outcome Measures
NameTimeMethod
The Total Number of New or Enlarging Hyperintense T2-Weighted Brain MRI Lesions From Week 12 to Week 24Week 12 to Week 24; MRI was performed at Weeks 12, 16, 20, and 24

The cumulative number of new or enlarging hyperintense T2-weighted brain MRI lesions from Week 12 to Week 24.

MRI scans were assessed and scored by an independent MRI analysis center with no knowledge of treatment assignment or outcomes.

Number of Participants With Treatment Emergent Adverse Events (TEAE) During Ozanimod ExposureFrom the first dose of ozanimod, either in the placebo-controlled or the blinded extension period, up to 4 weeks after the last dose; mean duration of exposure was 25.4, 30.9, 24.6, and 32.3 months in each treatment group respectively.

AEs are reported from the start of the placebo-controlled period for participants originally assigned to ozanimod and from the start of the extension period for participants who switched to ozanimod after Week 24.

Serious AEs were events that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability or incapacity, were congenital abnormalities/birth defects, or important medical events which may have required medical intervention to prevent one of the above outcomes.

The investigator assessed the severity of AEs as mild, moderate, or severe, and the relationship of each AE to treatment based on timing and other known factors such as clinical state, environment, or other therapies.

The Number of Gadolinium-Enhancing Lesions on Brain MRI Scan at Week 24Week 24

MRI scans were assessed and scored by an independent MRI analysis center with no knowledge of treatment assignment or outcomes.

Adjusted Annualized Relapse Rate (ARR) at Week 24Week 24

A relapse was defined as new or worsening neurological symptoms attributable to MS and preceded by a relatively stable or improving neurological state for at least 30 days. Symptoms must have persisted for \> 24 hours and not be attributable to confounding clinical factors. Relapses were confirmed when accompanied by objective neurological worsening based on examination by the blinded evaluator, consistent with an increase of ≥ 0.5 on the overall EDSS score relative to the most recent EDSS assessment, or 2 points on one of the functional system scale scores, or 1 point on ≥ two functional system scale scores.

Relapse rate was calculated as the total number of confirmed relapses divided by the total number of days in the study \* 365.

ARR was based on a Poisson regression model, adjusted for region, relapses within 24 months before the study, and presence of gadolinium-enhancing lesions at Baseline.

Number of Participants With Treatment Emergent Adverse Events (TEAE) During the Placebo-Controlled Treatment PeriodFrom first dose of study drug up to Week 24, or up to 28 days after the last dose for participants who did not enter the extension period.

An adverse event (AE) is any untoward medical occurrence that does not necessarily have a causal relationship with the investigational product (IP), including an abnormal laboratory finding, symptom or disease temporally associated with the use of an IP whether or not considered related to the IP. Serious AEs were events that resulted in death, were life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability or incapacity, were congenital abnormalities/birth defects, or important medical events which may have required medical intervention to prevent one of the above outcomes.

The investigator assessed the severity of AEs as mild, moderate, or severe, and the relationship of each AE to treatment as unrelated, unlikely, possible, probable, or related based on timing and other known factors such as clinical state, environment, or other therapies.
