What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Area under the concentration-time curve in PK group
Time Frame: Up to Week 24

To demonstrate PK comparability in terms of the area under the concentration time curve in patients with RRMS as follows:

  • Area under the concentration-time curve from time zero to Week 2 (AUC0-wk2)
  • Area under the concentration-time curve from Week 2 to Week 24 (AUCwk2-wk24)
Up to Week 24
Total number of new GdE lesions on T1-weighted brain MRI in Main study group
Time Frame: Up to Week 24
To demonstrate the equivalence of CT-P53 to reference drug (EU-Ocrevus and US-Ocrevus) in terms of efficacy in patients with RRMS as determined by the total number of new gadolinium-enhancing (GdE) lesions on T1-weighted brain magnetic resonance imaging (MRI)
Up to Week 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Absoulte CD19+ B-cell counts for PD assessments
Time Frame: Up to Week 96

To assess PD of CT-P53 and reference drug (EU-Ocrevus and US-Ocrevus) as follows:

• Absolute CD19+ B-cell counts
Up to Week 96
Area under the concentration-time curve in PK group
Time Frame: Up to Week 16
Area under the concentration-time curve from time zero to Week 16
Up to Week 16
Total body clearance in PK group
Time Frame: Up to Week 2
Total body clearance covering both administrations at Weeks 0 and 2 (CL)
Up to Week 2
Volume of distribution at steady state in PK group
Time Frame: Up to Week 2
Volume of distribution at steady state covering both administrations at Week 0 and 2 (Vss)
Up to Week 2
Safety: Immunogenecity
Time Frame: Up to Week 96
Number and percentage of patients with positive antidrug-antibody and neutralizing antibody results
Up to Week 96
Annualized Relapse Rate (ARR)
Time Frame: Up to Week 96
The total number of protocol-defined MS relapses for each patient will be counted and listed. Annualized relapse rate (ARR) will be calculated by the total number of protocol-defined relapses for all patients divided by time-in-study by patient.
Up to Week 96
Change in Expanded Disability Status Score (EDSS)
Time Frame: Up to Week 96

The EDSS score will be listed and descriptive statistics for actual value and change in EDSS score from baseline to Weeks 24, 48 and 96 will be summarized by treatment group and visit.

An increase ≥1.5 point from baseline EDSS score is defined as disability progression.

A reduction ≥1.0 point from baseline EDSS score is defined as disability improvement.
Up to Week 96
Change in Multiple Sclerosis Functional Composite Score (MSFCS)
Time Frame: Up to Week 96
There are three components to the MSFCS; (1) the average scores of two trials of T25-FW (2) the average scores on the 9-HPT (the two trials for each hand are averaged, converted to the reciprocals of the mean times for each hand and then the two reciprocals are averaged) (3) the number of correct answers from the PASAT-3. Multiple Sclerosis Functional Composite Score (MSFCS) is based on the concept that scores for these three dimensions (arm, leg, and cognitive functions) are combined to create a single score (the MSFCS) that can be used to detect change over time in MS patients
Up to Week 96
Total Number of Lesions on Brain Magnetic Resonance Imaging
Time Frame: Up to Week 96
The total number of lesions on brain MRI will be calculated as the cumulative sum of the individual number of the lesions at each scheduled visit
Up to Week 96
Volume of Hypointense Lesions on T1-weighted Brain Magnetic Resonance Imaging
Time Frame: Up to Week 96
Actual value of volume of hypointense lesions on T1-weighted brain MRI will be listed by treatment group and visit. Descriptive statistics for actual value and change in volume of hypointense lesions on T1-weighted brain MRI from baseline to Weeks 24, 48 and 96 will be summarized by treatment group
Up to Week 96
Brain Volume on Brain Magnetic Resonance Imaging
Time Frame: Up to Week 96
Change in brain volume is defined as the brain volume at pre-specified time point minus brain volume at baseline. Actual value of brain volume on brain MRI will be listed by treatment group. Descriptive statistics for actual value and percentage change in brain volume on brain MRI from baseline to Weeks 24, 48 and 96 will be summarized by treatment group.
Up to Week 96
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
Time Frame: Up to Week 96
All reported terms of AEs will be coded to system organ class (SOC) and preferred term (PT) according to the Medical Dictionary for Regulatory Activities (MedDRA) and severity grading of AEs will be recorded according to the CTCAE Version 5.0
Up to Week 96
