- NCT04544449
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
A study to evaluate the efficacy and safety of fenebrutinib on disability progression in adult participants with Primary Progressive Multiple Sclerosis (PPMS). All eligible participants will be randomized 1:1 to either daily oral fenebrutinib (and placebo) or intravenous (IV) ocrelizumab (and placebo) in a blinded fashion through an interactive voice or web-based response system (IxRS). 985 participants were enrolled and recruited globally. Participants who discontinue study medication early or discontinue from the study will not be replaced. The Open-Label Extension (OLE) phase is contingent on a positive benefit-risk result in the Primary Analysis of the study.

Ocrelizumab Placebo matched to fenebrutinib Participants will receive intravenous (IV) ocrelizumab and oral fenebrutinib-matching placebo. Fenebrutinib Fenebrutinib Participants will receive oral fenebrutinib and intravenous (IV) ocrelizumab-matching placebo. Ocrelizumab Ocrelizumab Participants will receive intravenous (IV) ocrelizumab and oral fenebrutinib-matching placebo.
- Primary Outcome Measures
Name Time Method Time to Onset of Composite 12-week Confirmed Disability Progression (cCDP12) Minimum of 120 weeks
- Secondary Outcome Measures
Name Time Method Time to Onset of 12-week Confirmed 4-point Worsening in Symbol Digit Modality Test (SDMT) Score Minimum of 120 weeks The SDMT is used for detecting the presence of cognitive impairment and changes in cognitive functioning over time and in response to treatment. The SDMT is brief, easy to administer test, and involves a simple substitution task. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Responses will be collected only orally, and administration time is approximately 5 minutes. The number of correct responses in 90 seconds will be considered the SDMT score. A decrease by 4 points on the SDMT score from baseline represents a clinically meaningful change in cognitive processing. The SDMT score ranges from 0 to 110. The higher the results, the better processing speed/working memory.
Percentage of Participants with Adverse Events (AEs) Up to 4.7 years Plasma Concentrations of Fenebrutinib at Specified Timepoints Up to 4.7 years Percent Change from Screening in Blood Neurofilament Light Chain (NfL) Levels Up to Week 120 Time to Onset of Composite 24-week CDP (cCDP24) Minimum of 120 weeks Time to Onset of 12-week CDP (CDP12) Minimum of 120 weeks Time to Onset of 24-week CDP (CDP24) Minimum of 120 weeks Percentage Change in Total Brain Volume Assessed by Magnetic Resonance Imaging (MRI) From Week 24 to Week 120 Change from Baseline in Participant-Reported Physical Impacts of Multiple Sclerosis (MS) Measured by the Multiple Sclerosis Impact Scale, 29-Item [MSIS-29] Physical Scale Baseline, Weeks 12, 24, 36, 48, 60, 72, 84, 96, 108 and 120 The MSIS-29, Version 2 is a 29-item patient-reported measure of the physical and psychological impacts of MS. Participants are asked to rate how much their functioning and well-being has been impacted over the past 14 days on a 4-point scale, from "Not at all" (1) to "Extremely" (4). The physical score is the sum of items 1-20, which is then transformed to a 0-100 scale. The psychological score is the sum of items 21-29, transformed to a 0-100 scale. Higher scores indicate a greater impact of MS.
