Eligibility
Key inclusion 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
Minimum age
18 Years
Maximum age
55 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Received prior therapy with alemtuzumab

screening; if abnormal cell count(s) returned to within normal limits (WNL),
eligibility could be reassessed

hemophilia, Von Willebrand's disease, disseminated intravascular coagulation,
fibrinogen deficiency, or clotting factor deficiency)

Summary
Brief summary
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.
