Study to Evaluate the Efficacy and Safety of Fenebrutinib Compared With Teriflunomide in Relapsing Multiple Sclerosis (RMS) (FENhance 2)

March 12, 2026 updated by: Hoffmann-La Roche

A Phase III Multicenter Randomized, Double-blind, Double-dummy, Parallel-group Study to Evaluate the Efficacy and Safety of Fenebrutinib Compared With Teriflunomide in Adult Patients With Relapsing Multiple Sclerosis

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 in a 1:1 ratio to receive either fenebrutinib or teriflunomide. At the end of the double-blind treatment (DBT) phase (after disclosure of the DBT results), the Sponsor will determine whether or not to initiate the open-label extension (OLE) phase of the study.

Total Number of T1 Gadolinium-enhancing (Gd+) Lesions, New and/or Enlarging T2-weighted Lesions, as Detected by Magnetic Resonance Imaging (MRI)
Time Frame: Baseline, Weeks 12, 24, 48 and 96
Baseline, Weeks 12, 24, 48 and 96
Percentage Change in Total Brain Volume From Week 24, as Assessed by MRI
Time Frame: From Week 24 to Week 96
From Week 24 to Week 96
Change in Participant-reported Physical Impacts of Multiple Sclerosis (MS), Measured by the Multiple Sclerosis, Impact Scale (29-Item), Version 2 (MSIS-29 v2) Physical Scale
Time Frame: Baseline, Weeks 12, 24, 36, 48, 60, 72, 84 and 96
The MSIS-29 v2 is a 29-item participant-reported measure of the physical and psychological impacts of MS. Participants are asked to rate how much their functioning and well-being have been impacted over the past 14 days on a 4-point scale, ranging 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.
Baseline, Weeks 12, 24, 36, 48, 60, 72, 84 and 96
Time to Onset of 12-week Confirmed 4-point Worsening in Symbol Digit Modality Test (SDMT) Score
Time Frame: Minimum 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 a brief, easy-to-administer test, involving 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 the 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.
Minimum of 96 weeks
Change From Baseline to Week 48 in the Concentration of Blood Neurofilament Light Chain (NfL)
Time Frame: Up to 48 weeks
Up to 48 weeks
Percentage of Participants With Adverse Events (AEs)
Time Frame: Up to 4.5 years
Up to 4.5 years
