Hoffmann-La Roche
ClinicalTrials.gov Identifier:
NCT01412333
First received: August 8, 2011
Last updated: July 28, 2014

  Purpose

This randomized, double-blind, double-dummy, parallel-group study will evaluate the efficacy and safety of ocrelizumab in comparison with Rebif (interferon beta

-1a) in patients with relapsing multiple sclerosis. Patients will be randomized to receive either in group A, ocrelizumab 600 mg intravenously (iv) every 24 wee ks plus Rebif placebo subcutaneously (sc) three times weekly, or, in group B, R ebif 8.8 mcg (Weeks 1+2)/22 mcg (Weeks 3+4)/44 mcg (Week 5 and following) sc thr ee times weekly plus ocrelizumab placebo iv every 24 weeks. Anticipated time on study treatment is 96 weeks.

Primary Outcome Measures:
  • Annualized protocol-defined relapse rate by 2 years in patients with relapsing MS [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to onset of sustained disability progression for at least 12 weeks [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Time to onset of sustained disability progression for at least 24 weeks [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Proportion of relapse-free patients [ Time Frame: Week 96 ] [ Designated as safety issue: No ]
  • Change in total T2 lesion volume as detected by brain MRI [ Time Frame: from baseline to Week 96 ] [ Designated as safety issue: No ]
  • Total number of new, and/or enlarging T2 hyperintense lesions as detected by brain MRI [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Change in Multiple Sclerosis Functional Composite Scale (MSFCS) score [ Time Frame: from baseline to Week 96 ] [ Designated as safety issue: No ]
  • Change in brain volume as detected by brain MRI [ Time Frame: from Week 24 to Week 96 ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Pharmacokinetics: Exposure to ocrelizumab (area under the concentration - time curve) [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
  • Immunogenicity: Human anti-human antibodies (HAHA) levels [ Time Frame: 96 weeks ] [ Designated as safety issue: No ]
