Trial Outcomes & Findings for Ocrelizumab for Preventing Clinical Multiple Sclerosis in Individuals With Radiologically Isolated Disease. (NCT NCT04877457)

NCT ID: NCT04877457

Last Updated: 2024-10-09

Results Overview

The primary efficacy endpoint for this study is to evaluate the efficacy of ocrelizumab compared with placebo on delaying the time to development of new radiological or clinical evidence of MS, defined as the time from baseline to first new T1 gadolinium-enhancing lesions and/or new or enlarging T2 lesions consistent with MS in participants OR first clinical evidence of MS, i.e., neurological event resulting from CNS demyelination as evidenced by acute or progressive clinical syndrome consistent with MS in participants.

Ocrelizumab - Participants Without a First Degree Family Member With Multiple Sclerosis
Three courses of ocrelizumab will be administered over the course of the study. Ocrelizumab: The first course of ocrelizumab will be administered as two 300 mg infusions at Week 0 (Day 1) and Week 2 (Day 15), with the subsequent second- and third-courses given as a single 600 mg infusion at Weeks 24 and 48.
Placebo - Participants Without a First Degree Family Member With Multiple Sclerosis.
Three courses of placebo will be administered over the course of the study. Placebo: Placebo will be administered at Week 0 (Day 1) and Week 2 (Day 15), with the subsequent second- and third-courses given at Weeks 24 and 48.
