Efficacy and Safety of Ofatumumab Compared to Teriflunomide in Patients With Relapsing Multiple Sclerosis (ASCLEPIOS I)

A Randomized, Double-blind, Double-dummy, Parallel-group Study Comparing the Efficacy and Safety of Ofatumumab Versus Teriflunomide in Patients With Relapsing Multiple Sclerosis

To compare the efficacy and safety of ofatumumab administered subcutaneously (sc) every 4 weeks versus teriflunomide administered orally once daily in patients with relapsing multiple sclerosis

Study Overview

• Status: Completed
• Conditions: Relapsing Multiple Sclerosis
• Intervention / Treatment: Drug: Teriflunomide-matching placebo capsules; Drug: Teriflunomide capsule; Drug: Matching placebo of ofatumumab subcutaneous injections; Drug: Ofatumumab subcutaneous injection

Detailed Description

This was a randomized, double-blind, double-dummy, active comparator-controlled, parallel-group, multi-center study with variable treatment duration in approximately 900 patients with relapsing multiple sclorosis (RMS). The maximal treatment duration in the study for an individual patient was 2.5 years.

Eligible patients were randomized to receive either experimental ofatumumab subcutaneous (s.c.) injections every 4 weeks or active comparator teriflunomide orally once daily. The dose regimen for ofatumumab for this study was a loading dose regimen of 20 mg at Day 1, Day 7 and Day 14, followed by a maintenance dose regimen of 20 mg administered every 4 weeks starting at Week 4. In order to blind for the different formulations, double-dummy masking was used i.e. all patients will take injections (containing either active ofatumumab or placebo) and oral capsules (containing either active teriflunomide or placebo).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Annualized Relapse Rate (ARR)	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).	Baseline up to 2.5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of New or Enlarging T2 Lesions on MRI Per Year (Annualized Lesion Rate)	Number of new/enlarging T2 lesions on last available MRI scan compared to baseline adjusted for different time of scans versus baseline due to variable follow up time in study	Baseline, yearly up to 2.5 years
Neurofilament Light Chain (NfL) Concentration in Serum	The NfL concentration (geometric mean concentration) was estimated by treatment and time point with using a repeated measures model on the basis of all evaluable log-transformed NfL values.	Month 3, 12 and 24
Annualized Relapse Rate (ARR) >8 Weeks After Onset of Treatment	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).	Baseline up to 2.5 years
Number of New or Enlarging T2 Lesions on MRI Per Year From Month 12 Until End of Study (EOS)	Number of new/enlarging T2 lesions on the last available MRI scan compared to Month 12 adjusted for different time of scans versus Month 12 due to variable follow up time in study.	Month 12 up to 2.5 years
Percent Change in T2 Lesion Volume Relative to Baseline	Percent change from baseline in total T2 lesion volume	Baseline, Month 12, Month 24
No Evidence of Disease Activity (NEDA-4)	NEDA-4 was defined as no 3-month confirmed disability worsening, no confirmed MS relapse, no new or enlarging T2 lesions compared to baseline, and the annualized rate of brain atrophy >-0.04%.	Baseline, Month 12, Month 24
Multiple Sclerosis Impact Scale (MSIS-29) Physical Impact Score Change From Baseline	MSIS-29 is a 29-item, self-administered questionnaire that includes 2 domains, physical and psychological. Responses are captured on a 4-point scale ranging from "not at all" (1) to "extremely" (4), where higher scores reflect greater impact on day to day life.	Baseline, every 6 months up to 2.5 years
Multiple Sclerosis Impact Scale (MSIS-29) Psychological Impact Score Change From Baseline	MSIS-29 is a 29-item, self-administered questionnaire that includes 2 domains, physical and psychological. Responses are captured on a 4-point scale ranging from "not at all" (1) to "extremely" (4), where higher scores reflect greater impact on day to day life.	Baseline, every 6 months up to 2.5 years
Annualized Relapse Rates (ARR) by NfL High-low Subgroups - Pooled Data	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).	Baseline up to 2.5 years
Number of New or Enlarging T2 Lesions Per Year by NfL High-low Subgroups - Pooled Data	Number of new or enlarging T2 lesions on MRI per year (annualized lesion rate).	Baseline, yearly up to 2.5 years
Pharmacokinetic (PK) Concentrations of Ofatumumab	Summary statistics of pharmacokinetic (PK) concentrations from trough samples collected within a 7-day window prior or at day of dosing.	Baseline, Weeks 4, 12, 24, 48, 96
3-month Confirmed Disability Worsening (3mCDW) Based on EDSS - Pooled Data	A 3-month confirmed disability worsening (3mCDW) was defined as an increase from baseline in Expanded Disability Status Scale (EDSS) score sustained for at least 3 months. For patients with a baseline EDSS of 0, the criterion for disability worsening was an increase in EDSS of ≥1.5, for patients with a baseline EDSS of 1 to 5 or ≥5.5, the criterion for disability worsening was an increase in EDSS of ≥1 or ≥0.5, respectively. 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.	Baseline, every 3 months up to 2.5 years
3-month Confirmed Disability Worsening (3mCDW) Based on EDSS - Study COMB157G2301	A 3-month confirmed disability worsening (3mCDW) was defined as an increase from baseline in Expanded Disability Status Scale (EDSS) score sustained for at least 3 months. For patients with a baseline EDSS of 0, the criterion for disability worsening was an increase in EDSS of ≥1.5, for patients with a baseline EDSS of 1 to 5 or ≥5.5, the criterion for disability worsening was an increase in EDSS of ≥1 or ≥0.5, respectively. This study was not powered for the analysis of this endpoint individually.
