A Study to Evaluate the Efficacy and Safety of Fenebrutinib Compared With Teriflunomide in Relapsing Multiple Sclerosis (RMS)

Phase 3
Active, not recruiting
Conditions
Relapsing Multiple Sclerosis
Interventions
Registration Number
NCT04586010
Lead Sponsor
Hoffmann-La Roche
Brief Summary

A study to evaluate the efficacy and safety of fenebrutinib on disability progression and relapse rate in adult participants with RMS. Eligible participants will be randomized 1:1 to either fenebrutinib or teriflunomide. At the end of the DBT phase (after disclosure of the DBT results), the Sponsor will determine whether or not to initiate the open-label extension phase of the study.

  • History of cancer including hematologic malignancy and solid tumors within 10 years of screening.
  • Known presence of other neurological disorders, that could interfere with the diagnosis of MS or assessments of efficacy or safety during the study and clinically significant cardiovascular, psychiatric, pulmonary, renal, hepatic, endocrine, metabolic or gastrointestinal disease.

  • Any concomitant disease that may require chronic treatment with systemic corticosteroids or immunosuppressants during the course of the study.
  • History of alcohol or other drug abuse within 12 months prior to screening.
  • History of or currently active primary or secondary (non-drug-related) immunodeficiency, including known history of human immunodeficiency virus (HIV) infection.

Total Number of T1 Gadolinium Enhancing (Gd+) Lesions, New and/or Enlarging T2-weighted Lesions as Detected by Magnetic Resonance Imaging (MRI)Baseline, Weeks 12, 24, 48 and 96
Percentage Change in Total Brain Volume from Week 24 as Assessed by MRIFrom Week 24 to Week 96
Change in Participant-Reported Physical Impacts of Multiple Sclerosis (MS) Measured by the Multiple Sclerosis, 29-Item [MSIS-29] Physical ScaleBaseline, Weeks 12, 24, 36, 48, 60, 72, 84 and 96

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.

Time to Onset of 12-week Confirmed 4-point worsening in Symbol Digit Modality Test (SDMT) ScoreMinimum of 96 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, is 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.

Change from Baseline to Week 48 in the Concentration of Blood Neurofilament Light Chain (NfL)Up to 48 weeks
Percentage of Participants with Adverse Events (AEs)Up to 4.5 years
Plasma Concentrations of Fenebrutinib at Specified TimepointsUp to 4.5 years
Time to Onset of Composite 12-week Confirmed Progression Independent of Relapse Activity (cPIRA12)Minimum of 96 weeks
