Trial Outcomes & Findings for Efficacy and Safety of Ofatumumab Compared to Teriflunomide in Patients With Relapsing Multiple Sclerosis (NCT NCT02792218)

Last Updated: 2021-10-01

Results Overview

ARR was the number of confirmed relapses in a year, calculated as the total number of relapses for all participants in the treatment group divided by the total participant-years of time in study. A confirmed MS relapse was defined as one accompanied by a clinically-relevant change in the EDSS performed by the Independent EDSS rater, i.e. an increase of at least 0.5 points on the EDSS score, or an increase of 1 point on two functional scores or 2 points on one functional score (excluding changes involving bowel/bladder or cerebral functional system). Comparisons were made to the previous rating (the last EDSS rating that did not occur during a relapse).

A 6-month confirmed cognitive decline was defined as a decrease from baseline of at least 4 points in SDMT score sustained for at least 6 months. Processing speed was measured by the Symbol Digit Modalities Test (SDMT) score. SDMT measures the time to pair abstract symbols with specific numbers. The test requires visuoperceptual processing, working memory, and psychomotor speed. The score is the number of correctly coded items in 90 seconds. (max=110, min=0). Higher scores indicate improvement. Lower scores indicate worsening. This study was not powered for the analysis of this endpoint individually.

The patient is directed to walk 25 feet quickly and safely as possible from one marked end to the other. The time is calculated from the initiation of the patient instructed to begin, until the patient has reached the 25-foot mark. This study was not powered for the analysis of this endpoint individually. It was pre-specified in the study protocol to combine the data from this study with study COMB157G2302 to address this endpoint.

9 Hole Peg Test is a test of upper limb function. Participants place 9 pegs on pegboard and remove pegs and this is timed for each hand. Time recorded in seconds. Longer time indicates poorer upper limb function. 20% improvement is defined as 20% shorter time in seconds. This study was not powered for the analysis of this endpoint individually. It was pre-specified in the study protocol to combine the data from this study with study COMB157G2302 to address this endpoint.

A 6-month confirmed disability improvement (6mCDI) sustained until EOS was defined as a decrease from baseline EDSS sustained until EOS. For patients with a baseline EDSS of 0 to 1.5, no disability improvement was possible based on the protocol definition of an improvement; for patients with a baseline EDSS of ≥2 to 6 or ≥6.5 to 9.5, the criterion for disability improvement was a decrease in EDSS of ≤1 or ≤0.5, respectively. This study was not powered for the analysis of this endpoint individually.
