Proportion of patients relapsed (PPR) at 2 years
The number of new or newly enlarging T2 hyperintense lesions, new T1 hypointense lesions, and gadolinium-enhancing (Gd+) lesions
Annualized relapse rate (ARR)
Time to confirmed disability progression
ARR at 2 years

PPR
Time to confirmed disability progression
Patients who had experienced at least 1 relapse over the year preceding the trial or had a brain magnetic resonance imaging (MRI) scan demonstrating at least 1 Gd+ lesion within 6 weeks of randomization
Patients' scores on the Expanded Disability Status Scale were assessed, and scores could range from 0 to 5
Patients who were treated with interferon-beta or glatiramer acetate within 3 months of randomization
Patients who had an infusion disease-modifying therapy or other selected therapies within 6 months of randomization
Patients with progressive forms of multiple sclerosis or any major disease that would preclude participation in a clinical trial
Neurological evaluations were performed at baseline, every 3 months, and at the time of suspected relapse
MRI evaluations were performed at baseline, month 6, and years 1 and 2 in a subset of patients (44% in Study 1 and 48% in Study 2)
