Descriptive Information

• Brief Title: A Study of the Efficacy and Safety of Ocrelizumab in Patients With Relapsing-Remitting Multiple Sclerosis
• Official Title: Phase II, Multicenter, Randomized, Parallel-Group, Partially Blinded, Placebo and Avonex Controlled Dose Finding Study to Evaluate the Efficacy As Measured by Brain MRI Lesions, and Safety of 2 Dose Regimens of Ocrelizumab in Patients With RRMS
• Brief Summary: This is a phase II, multicenter, randomized, parallel-group, partially blinded, placebo and Avonex (interferon beta-1a) controlled dose finding study to evaluate the efficacy as measured by brain MRI lesions, and safety of 2 dose regimens of ocrelizumab in participants with Relapsing Remitting Multiple Sclerosis (RRMS).

• Condition: Multiple Sclerosis, Relapsing-Remitting

Intervention

• Drug: Placebo
  Placebo matching to ocrelizumab administered as IV infision in Cycle 1 Day 1.
• Drug: Ocrelizumab
  Ocrelizumab 300 mg was administered in cycle 1 followed by an infusion of ocrelizumab 600 mg on Day 1. A single infusion of ocrelizumab 600 mg was administered on Day 1 of cycles 3 and 4.

Study Arms

• Placebo Comparator: Placebo
  Participants received two intravenous (IV) infusions of matching placebo separated by 14 days in Cycle 1, followed by two infusions of ocrelizumab 300 mg separated by 14 days in cycle 2. A single infusion of ocrelizumab 600 mg was administered on Day 1 of cycles 3 and 4. Each cycle was of 168 days.
  Intervention: Drug: Placebo
• Experimental: Ocrelizumab 600 mg
  Participants two IV infusions of ocrelizumab 300 mg separated by 14 days in Cycle 1, followed by an infusion of ocrelizumab 600 mg on Day 1 and an infusion of placebo on Day 15 of Cycle 2. A single infusion of ocrelizumab 600 mg was administered on Day 1 of Cycles 3 and 4. Each cycle was of 168 days.
  Intervention: Drug: Ocrelizumab
• Experimental: Ocrelizumab 1000 mg
  Participants received two IV infusions of ocrelizumab 1000 mg separated by 14 days in Cycle 1, followed by an infusion of ocrelizumab 1000 mg on Day 1 and an infusion of placebo on Day 15 of Cycle 2. A single infusion of ocrelizumab 1000 mg was administered on Day 1 of Cycle 3 and a single infusion of ocrelizumab 600 mg was administered on Day 1 of Cycle 4. Each cycle was of 168 days.
  Intervention: Drug: Ocrelizumab
• Active Comparator: Avonex
  Participants received weekly intramuscular injections of Avonex 30 microgram (mcg) in Cycle 1, followed by two infusions of OCR 300 mg separated by 14 days in Cycle 2. A single infusion of ocrelizumab 600 mg was administered on Day 1 of Cycles 3 and 4. Each cycle was of 168 days.
