Last verified: November 2012

The purpose of this study is to establish the efficacy and safety of two different doses of alemtuzumab as a treatment for relapsing-remitting multiple sclerosis (MS), in comparison with Rebif® (interferon beta-1a). The study will enroll patients who have received an adequate trial of disease-modifying therapies but continued to relapse while being treated, and who meet a minimum severity of disease as measured by magnetic resonance imaging (MRI). Patients will have monthly laboratory tests and comprehensive testing every 3 months.

Condition Intervention Phase
Multiple Sclerosis, Relapsing-Remitting
Biological: alemtuzumab
Biological: interferon beta-1a (Rebif®)
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Phase 3 Randomized, Rater- and Dose-Blinded Study Comparing 2 Annual Cycles of IV [Low]- and High-Dose Alemtuzumab to 3x Weekly SC Interferon Beta-1a (Rebif®) in Relapsing-Remitting Multiple Sclerosis Patients Who Have Relapsed on Therapy

Primary Outcome Measures:
  • Time to Sustained Accumulation of Disability (SAD) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Relapse Rate [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of patients who are relapse free at Year 2 [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Change from baseline in EDSS (Expanded Disability Status Scale) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Acquisition of disability as measured by change from baseline in Multiple Sclerosis Functional Composite (MSFC) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Percent change from baseline in MRI-T2 hyperintense lesion volume at Year 2 [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Enrollment: 840
Study Start Date: October 2007
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: alemtuzumab 12 mg Biological: alemtuzumab
12 mg per day administered through IV, once a day for 5 consecutive days at Month 0 and 12 mg per day administered through IV, once a day for 3 consecutive days at Month 12
Experimental: alemtuzumab 24mg Biological: alemtuzumab
24 mg per day administered through IV, once a day for 5 consecutive days at Month 0 and 24 mg per day administered through IV, once a day for 3 consecutive days at Month 12 Note: The 24 mg alemtuzumab dose is closed to enrollment.
Active Comparator: interferon beta-1a (Rebif ®) Biological: interferon beta-1a (Rebif®)
44 mcg administered 3-times weekly by SC injections for 2 years

Detailed Description:

Every patient will receive active treatment; there is no placebo. The 24 mg alemtuzumab dose is closed to enrollment so newly enrolled patients will be randomly assigned to treatment with either 12 mg alemtuzumab or Rebif® at a 2:1 ratio (ie, 2 given 12 mg or 24 mg alemtuzumab for every 1 given Rebif®). Alemtuzumab will be administered in two annual cycles, once at the beginning of the study and again 1 year later. Rebif® will be self-injected 3 times per week for 2 years. All patients will be required to return to their study site every 3 months for neurologic assessment. In addition, safety-related laboratory tests will be performed at least monthly. Participation in this study will end 2 years after the start of treatment for each patient. Additionally, patients who receive alemtuzumab may be followed in the CAMMS03409 Extension Study (NCT00930553) for safety and efficacy assessments. Patients who receive Rebif® and complete 2 years on study may be eligible to receive alemtuzumab in the Extension Study.
