Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ublituximab + Oral Placebo
Participants were administered ublituximab 150 milligrams (mg), intravenous (IV) infusion over 4 hours (h) on Day 1 followed by 450 mg over 1 h on Days 15, 168, 336 and 504 (Week 72) along with the oral placebo once daily (QD) from Day 1 up to the last day of Week 95.
Administered as an IV infusion.
Other Names:
  • TG-1101
Administered orally.
Active Comparator: Teriflunomide + IV Placebo
Participants were administered teriflunomide 14 mg tablet, orally, QD from Day 1 up to the last day of Week 95 along with the placebo IV infusion on Days 1, 15, 168, 336 and 504 (Week 72).
Film-coated tablets administered orally.
Administered as an IV infusion.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Annualized Relapse Rate (ARR)
Time Frame: Up to 96 weeks
ARR is defined as the number of Independent Relapse Adjudication Panel (IRAP)-confirmed relapses per participant year. The estimate of ARR for a treatment group is the total number of relapses for participants in the respective treatment group divided by the sum of treatment duration for participants in that specific treatment group.
Up to 96 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total Number of Gadolinium (Gd)-Enhancing T1-Lesions Per Magnetic Resonance Imaging (MRI) Scan Per Participant
Time Frame: Weeks 12, 24, 48, and 96
The total number of Gd-enhancing T1-lesions were calculated as the sum of the individual number of lesions at Weeks 12, 24, 48, and 96, divided by the total number of MRI scans of the brain.
Weeks 12, 24, 48, and 96
Total Number of New and Enlarging T2 Hyperintense Lesions (NELs) Per MRI Scan Per Participant
Time Frame: Weeks 24, 48, and 96
The total number of NELs were calculated as the sum of the individual number of lesions at Weeks 24, 48, and 96, divided by the total number of MRI scans of the brain.
Weeks 24, 48, and 96
Time to Confirmed Disability Progression (CDP) for at Least 12 Weeks
Time Frame: Up to Week 96
12-week CDP is defined as an increase in EDSS at least 1 point higher than the baseline EDSS if the baseline EDSS is ≤5.5 or at least 0.5 higher than the baseline EDSS if the baseline EDSS is >5.5. The EDSS is based on a standard neurological examination, (pyramidal, cerebellar, brainstem, sensory, bowel and bladder, visual, and cerebral) and ambulation function system assessments. The EDSS disability scale ranges in 0.5-point steps from 0 (normal) to 10 (death) where higher scores indicate disability. The time to onset of 12-week CDP is the time to progression to the EDSS change defined above.
Up to Week 96
Percentage of Participants With No Evidence of Disease Activity (NEDA)
Time Frame: Week 24 up to Week 96
A participant with NEDA is defined as a participant without relapses confirmed by the IRAP, without MRI activities (no T1 Gd+ lesions and no new/enlarging T2 lesions), and no 12-week CDP. Any evidence of disease activity from Week 24 to Week 96 was counted as not reaching NEDA. Any evidence of disease activity before Week 24 was not counted.
Week 24 up to Week 96
Percentage of Participants With Impaired Symbol Digit Modalities Test (SDMT)
Time Frame: Baseline up to Week 96
The SDMT involves a simple substitution task using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Responses are done verbally. The administration time is approximately 5 minutes. The total SDMT score for each visit ranging from 0-110 is defined as the total number of correct answers reported in the case report form (CRF), where high scores indicate better outcome. Impaired SDMT is defined as a decrease from baseline of at least 4 points at any post-baseline assessment up to the Week 96 visit.
Baseline up to Week 96
Percent Change From Baseline in Brain Volume
Time Frame: Baseline up to Week 96
Baseline up to Week 96
Percentage of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)
Time Frame: From the first dose of study drug through the end of the study (up to approximately 116 weeks)
An adverse event (AE) is any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. A Serious AE is defined as any untoward medical occurrence that: results in death, is immediately life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, and/or causes a congenital anomaly/birth defect. A TEAE is an AE that starts or worsens after receiving study drug.
From the first dose of study drug through the end of the study (up to approximately 116 weeks)
