Primary Outcome(s)

Main Objective: To determine the annualized relapse rate (ARR) in subjects with RMS after 96 weeks (approximately 2 years) treatment with IV infusion of ublituximab/oral placebo compared to 14 mg teriflunomide/IV placebo taken orally daily.

Timepoint(s) of evaluation of this end point: 96 weeks

Primary end point(s): The primary efficacy endpoint is ARR (Annualized Relapse Rate) defined as the number of confirmed relapsed per-subject year. The estimate of ARR for a treatment group will be the total number of relapsed for subjects in the respective treatment group divided by the sum of duration on study for subjects in that specific treatment group.

Secondary Objective: The secondary objectives are to examine the effects of ublituximab/oral placebo as compared to teriflunomide/IV oral placebo as follows:
1. On MRI parameters,
2. The percentage with accumulation of disability,
3. Time to onset of confirmed disability progression for at least 12 weeks,
4. The percentage of subject with a relapse,
5. Time to first confirmed relapse,
6. The percentage of subjects with no evidence of disease activity (NEDA), and
7. To evaluate the safety of ublituximab/oral placebo, as determined by adverse events (AEs) and serious adverse event (SAEs), including MS worsening.

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: Week 12, 24, 48, 72, 96

Secondary end point(s): Key secondary efficacy endpoints are as follows:
1. MRI parameters,
a. The total number of gadolinium enhancing (Gd-enhancing) T1-lesions per MRI scan over the treatment period
b. Volume of hypointense post-gadolinium T1 lesion component (black holes)
c. Volume of T2 lesion
d. Brain volume changes
2. The percent of subjects with no evidence of disease activity (NEDA)
a. NEDA is defined as subjects without relapses, MRI activities (no T1 Gd+ lesions and no new/enlarging T2 lesions), and no 12-week
confirmed disability progression.
3. The percentage of subjects with accumulation of disability
a. Time to onset of confirmed disability progression for at least 12 weeks
b. Percent of subjects free of disability progression at 6 months, 1 year, and 2 years.
4. The percentage of subjects with a relapse
5. Time to first confirmed relapse
