Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis, Study Two
Trial ID or NCT#
Status
NOT RECRUITING
Purpose
The purpose of this study was to establish the efficacy and safety of two different doses of alemtuzumab (Lemtrada™) as a treatment for relapsing-remitting multiple sclerosis (MS), in comparison with subcutaneous interferon beta-1a (Rebif®). The study enrolled participants who had received an adequate trial of disease-modifying therapies but experienced at least 1 relapse during prior treatment, and who met a minimum severity of disease as measured by magnetic resonance imaging (MRI). Participants had monthly laboratory tests and comprehensive testing every 3 months.
Official Title
A Phase 3, Randomized, Rater- and Dose-Blinded Study Comparing Two Annual Cycles of Intravenous Low- and High-Dose Alemtuzumab to Three-Times Weekly Subcutaneous Interferon Beta 1a (Rebif®) in Patients With Relapsing Remitting Multiple Sclerosis Who Have Relapsed On Therapy
Eligibility Criteria
- - Signed informed consent form (ICF) - Age 18 to 55 years (inclusive) as of the date the ICF was signed - Diagnosis of MS per update of McDonald criteria - Onset of MS symptoms (as determined by a neurologist; could be retrospectively) within 10 years of the date the ICF was signed - Expanded Disability Status Scale (EDSS) score 0.0 to 5.0 (inclusive) at Screening - Greater than or equal to (>=) 2 MS attacks (first episode or relapse) occurring in the 24 months prior to the date the ICF was signed, with >=1 attack in the 12 months prior to the date the ICF was signed, with objective neurological signs confirmed by a physician, nurse practitioner, or other Genzyme-approved health-care provider and the objective signs could be identified retrospectively - >=1 MS relapse during treatment with a beta interferon therapy or glatiramer acetate after having been on that therapy for >=6 months within 10 years of the date the ICF was signed - MRI scan demonstrating white matter lesions attributable to MS and meeting at least 1 of the following criteria, as determined by the neurologist or a radiologist: >=9 time constant 2 (T2) lesions at least 3 millimeter (mm) in any axis; a gadolinium- (Gd-) enhancing lesion at least 3 mm in any axis plus >=1 brain T2 lesions; and a spinal cord lesion consistent with MS plus >=1 brain T2 lesion
- - Received prior therapy with alemtuzumab - Current participation in another clinical study or previous participation in CAMMS323 (Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis, CARE-MS I) - Treatment with natalizumab, methotrexate, azathioprine, or cyclosporine in the past 6 months. Participants who received one of these medications more than 6 months before the date the ICF was signed were eligible for study entry if approval was granted by Genzyme - Any progressive form of MS - History of malignancy (except basal skin cell carcinoma) - CD4 +, CD8 +, CD19 + (that is, absolute CD3 + CD4 + , CD3 + CD8 + , or CD19 + /mm 3 ) count, absolute neutrophil count less than (<) lower limit of normal (LLN) at screening; if abnormal cell count(s) returned to within normal limits (WNL), eligibility could be reassessed - Known bleeding disorder (for example, dysfibrinogenemia, factor IX deficiency, hemophilia, Von Willebrand's disease, disseminated intravascular coagulation, fibrinogen deficiency, or clotting factor deficiency) - Significant autoimmune disease including but not limited to immune cytopenias, rheumatoid arthritis, systemic lupus erythematosus, other connective tissue disorders, vasculitis, inflammatory bowel disease, severe psoriasis - Presence of anti-thyroid stimulating hormone (TSH) receptor (TSHR) antibodies (that is, above the LLN) - Active infection or at high risk for infection
