E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
•To evaluate the efficacy of ocrelizumab treatment compared with placebo-in patients on progression of upper limb disability, measured based on the time to 20% worsening from baseline in the 9-Hole Peg Test (9-HPT) confirmed for at least 12 weeks in all randomized patients and in patients with magnetic resonance imaging (MRI) activity |
|
E.2.2 | Secondary objectives of the trial |
•To evaluate the efficacy of ocrelizumab compared with placebo for all randomized patients by the time to 24 week confirmed 20% increase from baseline in 9-HPT, time to 12-week and 24-week confirmed disability progression (CDP) in expanded disability status scale (EDSS)
•To evaluate the efficacy of ocrelizumab compared with placebo for all patients by the % change in total volume of T2 lesions and total brain volume
•To evaluate the safety of ocrelizumab compared with placebo and over time for all patients who received ocrelizumab and until they receive any other immunomodulatory or immunosuppressive treatments by the proportion of patients with adverse events, laboratory abnormalities
•To assess the immunogenicity, by the presence of anti-drug antibody to ocrelizumab during the study relative to baseline and the relationship to pharmacokinetics (PK), pharmacodynamics, efficacy and safety
•To characterize the PK profile of the ocrelizumab and its PD, measured by blood B-cell levels |
