Current Secondary Outcome Measures ICMJE; (submitted: May 9, 2017)	Time to First Documented Relapse [ Time Frame: 2 years post treatment (IMP) administration ]Time to First Documented Relapse was calculated using Kaplan-Meier survival methods.; Mean Number of Relapses Per Subject [ Time Frame: 2 years post treatment (IMP) administration ]Relapse was defined as new, worsening or recurrent neurological symptoms attributed to multiple sclerosis that last for at least 24 hours without fever or infection, or adverse reaction to prescribed medication, preceded by a stable or improving neurological status of at least 30 days. Mean and standard deviation were reported.; Number of Relapse-Free (Documented) Subjects [ Time Frame: 2 years post treatment (IMP) administration ]The relapse-free patients after 2 years of treatment was calculated using Cochran-Mantel-Haenszel test using the site as control variable.; Cumulative Probability of Progression of Disability (Kaplan-Meier Curves) [ Time Frame: Baseline up to week 96 ]Disability progression was assessed using Expanded disability status scale (EDSS). EDSS assesses disability in 8 functional systems. An overall score ranging from 0 (normal) to 10 (death due to MS) was calculated. A one-point increase on the EDSS scale was considered as a progression in disability. The time to disability progression was summarized using Kaplan-Meier survival methods. The cumulative probability of confirmed disease progression at each visit was obtained by applying a Kaplan-Meier method to the time to confirmed disease progression.; Number of New or Extended Lesions by T1- and T2-Weighted Magnetic Resonance Imaging (MRI) [ Time Frame: 2 years post treatment (IMP) administration ]; Changes From Baseline in Measured Lesion Load (T2) [ Time Frame: Baseline, Week 96 ]Baseline defined as last value recorded prior to first intake of study drug.; Change From Baseline in Measurement and Evaluation of Cognitive Ability by Paced Auditory Serial Addition Task (PASAT) Total Score At Week 96 [ Time Frame: Baseline, Week 96 ]The Adapted Paced Auditory Serial Addition Task (PASAT) is a measure of cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability. The total score for PASAT is the total number of correct answers (out of 60, for a total possible score ranging from 0-60 with higher score indicates higher auditory processing speed) for each trial. Change from baseline in PASAT total score at Week 96 was summarized.; Change From Baseline in Euro Quality of Life Scale (EuroQol) 5-Dimension-3 Level (EQ-5D-3L) [ Time Frame: 2 years post treatment (IMP) administration ]The EQ-5D health questionnaire is a generic self-reported health-related quality of life instrument that includes a 100 mm Visual Analog Scale (VAS) to measure the general health state, as well as 5 items corresponding to one dimension each: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. In this study, the VAS scale is not collected and the version 3L of the scale was used: Each dimension had 3 possible levels: 1 = no problem, 2 = some problems and 3 = extreme problems. EQ-5D-3L weighted health state index exists that combines the score of the 5 dimensions and ranges from 0 to 1 (full health). The variables for the 5 dimensions of the EQ-5D descriptive system was named 'mobility','selfcare', 'activity', 'pain', and 'anxiety'. The 5 variables contained the values for the different dimensions in the EQ-5D health profile (i.e. 1, 2, or 3).; Number of Subjects With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs and Abnormal Clinical Laboratory [ Time Frame: Baseline up to end of treatment (week 96) ]A serious TEAE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect and TEAE was defined as newly occurring or worsening after first dose. Clinical laboratory abnormalities are expected to be reported as adverse events if they met any criterion for seriousness, led to treatment discontinuation, required a medical intervention or were considered clinically significant by the investigator.

Official Title ICMJE	A Multicentre, Randomised, Double-blind, Placebo-controlled Study of the Efficacy of Supplementary Treatment With Cholecalciferol (Vitamin D3) in Patients With Relapsing- Multiple Sclerosis (RMS) Treated With Subcutaneous Interferon Beta-1a 44 µg 3 Times Weekly
Brief Summary	The aim of this multicentre, randomised, double-blind, placebo-controlled study is to evaluate the efficacy and safety of supplementary treatment with cholecalciferol (vitamin D3) in subjects with relapsing multiple sclerosis (R MS) treated with subcutaneous (s.c.) interferon beta-1a 44 microgram (mcg) [Rebif] 3 times weekly. The subjects will be divided into 2 groups, one receiving cholecalciferol 100,000 IU twice monthly along with Rebif treatment and the other group will be on placebo along with Rebif treatment. A total of 200 subjects will be recruited in 20-30 centres in France.
