Percentage of Participants With Sustained Accumulation of Disability (SAD)

Assessment method [1]
0

EDSS is an ordinal scale in half-point increments that quantifies disability in participants with MS. It assesses 7 functional systems (visual, brainstem, pyramidal, cerebellar, sensory, bowel/bladder and cerebral) as well as ambulation. EDSS total score: 0 (normal neurological examination) to 10 (death due to MS). As measured by EDSS score, SAD was defined as increase of at least 1.5 points for participants with Baseline score of 0 and increase of at least 1.0 point for participants with a Baseline score of 1.0 or more; and the increase persisted for at least next 2 scheduled assessments, that is, 6 consecutive months. Onset date of SAD was date of first EDSS assessment that began 6 month consecutive period of SAD. Participants who did not reach SAD endpoint were censored at their last visit. Percentage of participants with SAD, estimated by Kaplan-Meier (KM) method, was reported.

Annualized Relapse Rate

Assessment method [2]

0
Relapse was defined as new neurological symptoms or worsening of previous neurological symptoms with an objective change on neurological examination, attributable to multiple sclerosis that lasted for at least 48 hours, that were present at normal body temperature, and that were preceded by at least 30 days of clinical stability. Annualized relapse rate was estimated through negative binomial regression with robust variance estimation and covariate adjustment for geographic region using observed number of relapses as dependent variable, the log total amount of follow-up from date of first study treatment for each participant as an offset variable, and treatment group and geographic region as model covariates.

EDSS is an ordinal scale in half-point increments that quantifies disability in participants with MS. It assesses the 7 functional systems (visual, brainstem, pyramidal, cerebellar, sensory, bowel/bladder and cerebral) as well as ambulation. EDSS total score ranges from 0 (normal neurological examination) to 10 (death due to MS). Change was calculated by subtracting Baseline value from value at Year 2.

Change From Baseline in Multiple Sclerosis Functional Composite (MSFC) Score at Year 2
Query!
Assessment method [3]
0
0
MSFC is a multidimensional measure consisting of quantitative tests of ambulation (Timed 25-Foot Walk), manual dexterity (9-Hole Peg Test; 9HPT), and cognitive function (Paced Auditory Serial Addition Test; PASAT). The MSFC score was calculated as the mean of the Z-scores of the 3 components. A Z-score was calculated by subtracting the mean of the reference population from the test result, then dividing by the standard deviation of the reference population. Higher Z-scores reflected better neurological function and a positive change from Baseline indicates improvement. An increase in score indicated an improvement (Z-score range: -3 to +3). Acquisition of disability was measured by change from Baseline in MSFC score at Year 2.

Summary
Brief summary
The purpose of this study was to establish the efficacy and safety of alemtuzumab (Lemtrada™)
as a treatment for relapsing-remitting multiple sclerosis (MS), in comparison with
subcutaneous (SC) interferon beta-1a (Rebif®). The study had enrolled participants who had
not previously received MS disease-modifying therapies. Participants had monthly laboratory
tests and comprehensive testing every 3 months.
