General information about the trial
|
|||
Main objective of the trial |
The main objectives of the study were to examine:
1) the long term safety and efficacy of alemtuzumab in multiple sclerosis (MS) subjects who received alemtuzumab during prior company-sponsored studies CAMMS223, CAMMS323, and
CAMMS324;
2) the safety and efficacy of as-needed alemtuzumab retreatment in these previously alemtuzumab-treated subjects;
3) the safety and efficacy of 2 fixed, annual, alemtuzumab courses followed by optional, as-needed, retreatment in subjects who had previously received subcutaneous (SC) interferon beta-1a (INFB-1a) during CAMMS223, CAMMS323, or CAMMS324.
|
||
Protection of trial subjects |
Subjects were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time in language and terms appropriate for the subject and considering the local culture. During the course of the trial, subjects were provided with individual subject cards indicating the nature of the trial the subject is participating, contact details and any information needed in the event of a medical emergency.
Collected personal data and human biological samples were processed in compliance with the Sanofi-Aventis Group Personal Data Protection Charter ensuring that the Group abides by the laws governing personal data protection in force in all countries in which it operates.

Recruitment details |
This extension study enrolled subjects from previous 3 studies: CAMMS223 (NCT00050778), CAMMS323 (NCT00530348), and CAMMS324 (NCT00548405). Subjects were enrolled in this study only after their Month 24 visit in CAMMS323 and CAMMS324. CAMMS223 subjects were enrolled within 6 months once their site received approval of extension study. | ||||||||||||||||||||||||||||

Arm description |
Subjects enrolled from any of the prior studies received long-term follow-up in this study. Subjects randomised to receive interferon beta-1a (IFNB-1a) in prior studies received alemtuzumab 12 mg/day infusion intravenously (IV) once daily (QD) for 5 consecutive days in treatment Course 1, and for 3 consecutive days in treatment Course 2, 12 months later in this study. Subjects who received 2 treatment courses with alemtuzumab could be treated with additional alemtuzumab courses of 12 mg/day infusion IV QD, for 3 consecutive days at least 48 weeks after the prior course if they had documented evidence of resumed disease activity (defined as >=1 protocol-defined relapse and/or >=2 new or enlarging brain or spinal lesions on magnetic resonance imaging [MRI]), unless they met safety-related retreatment disqualifying criteria. | ||||||||||||||||||||||||||||

End point description |
Relapse was defined as new neurological symptoms or worsening of previous neurological symptoms with an objective change on neurological examination, attributable to MS that last for at least 48 hours, present at normal body temperature, and that were preceded by at least 30 days of clinical stability. ARR was obtained from the total number of confirmed relapses that occurred during the treatment period divided by the sum of all subjects involved in certain treatment groups. ARR was estimated through negative binomial regression with robust variance estimation and covariate adjustment for geographic region. Subset of full analysis set (FAS - defined as all subjects randomised in CAMMS223, CAMMS323, and CAMMS324 and who received at least 1 dose of study drug) ) included subjects who had received at least 1 dose of alemtuzumab in CAMMS323 and CAMMS324.

End point description |
SF-36 is a subject reported standardized survey designed to assess generic health related quality of life.

The score range for each of the 8 health aspects was from 0 (poor health) to 100 (better health), higher scores indicating good health condition. Scores of first four health aspects (1 - 4) were aggregated to derive the PCS ranging from 0 (worst) to 100 (best), where higher scores indicated good health condition.
