Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Using Wheelchair or Being Bedridden Assessed by Expanded Disability Status Scale (EDSS) Score 7.0 or Higher	EDSS is a scale based on standardized neurological examination which comprised of optic, brain stem, pyramidal, cerebellar, sensory & cerebral functions, as well as walking ability. EDDS is a scale from 0-10 that evaluates a person with Multiple Sclerosis (MS) disability/neurologic function level where 0=normal and 10=death due to MS. Score of 7.0 is defined as unable to walk beyond approximately 5 meters even with aid, essentially restricted to wheelchair; wheels self in standard wheelchair and transfers alone; up and about in wheelchair some 12 hours a day. Score of 8.0 is defined as Essentially restricted to bed or chair or perambulated in wheelchair, but may be out of bed itself much of the day; retains many self-care functions; generally has effective use of arms.	3 months prior to study visit 1. Retrospectively from end of parent study (NCT00213135, NCT00641537 and NCT00725985) to study visit 1 (study visit 1 occurred up to 3 months from screening)
Secondary	Percentage of Participants With Expanded Disability Status Scale (EDSS) Score 6.0 or Higher	EDSS is a scale based on standardized neurological examination which comprised of optic, brain stem, pyramidal, cerebellar, sensory & cerebral functions, as well as walking ability. EDDS is a scale from 0-10 that evaluates a person with MS disability/neurologic function level where 0= normal and 10= death due to MS. Score of 6.0 is defined as "intermittent or unilateral constant assistance (cane, crutch and brace) required to walk about 100 meters with or without resting".	At study visit 1. Retrospectively after last IMP administration from parent study (NCT00213135, NCT00641537 and NCT00725985) to study visit 1 (study visit 1 occurred up to 3 months from screening)
Secondary	Clinical and Demographic Characteristic: Age, Disease Duration	Clinical and demographic characteristics including age and disease duration is reported in the form of long term responders and non-responder. Here long term responder is defined as study participants not requiring disease modifying drug (DMD) 4 years or later following their last dose of IMP in parent study. Non-responder is defined as study participants requiring DMD less than 4 years following their last dose of IMP in parent study.	At study visit 1, occurred up to 3 months from screening (Retrospective analysis of medical record of parent study-NCT00213135, NCT00641537 and NCT00725985)
Secondary	Number of Participants in Each Category of Clinical and Demographic Characteristics	Clinical and demographic characteristics included gender, race, disease classification (relapsing remitting multiple sclerosis [RRMS], Secondary Progressive Multiple Sclerosis [SPMS], unknown & no MS disease), Prior use of DMDs & high-disease activity (HAD) status, education level and employment status. Number of participants in each category of clinical and demographic characteristics were reported in form of long term responders & non-responder. Here long term responder is defined as participants not requiring DMD 4 years or later following their last dose of IMP in parent study. Non-responder is defined as study participants requiring DMD < 4 years following their last dose of IMP in parent study.	At study visit 1, occurred up to 3 months from screening (Retrospective analysis of medical record of parent study-NCT00213135, NCT00641537 and NCT00725985)
Secondary	Clinical Characteristic: Expanded Disability Status Scale (EDSS) Score	EDSS is a scale based on standardized neurological examination which comprised of optic, brain stem, pyramidal, cerebellar, sensory & cerebral functions, as well as walking ability. EDSS scores range from 0.0 (normal) to 10.0 (dead). Clinical characteristics of EDSS score in form of long-term responders & non-responder was reported for at parent study baseline (based on retrospective data collection [based on chart review] at study visit 1) & study visit 1. Here long term responder is defined as study participants not requiring DMD 4 years or later following their last dose of IMP in parent study. Non-responder is defined as study participants requiring DMD < 4 years following their last dose of IMP in parent study.	At study visit 1, occurred up to 3 months from screening (Retrospective analysis of medical record of parent study-NCT00213135, NCT00641537 and NCT00725985)
Secondary	Clinical Characteristic: Number of Relapses	Relapse was defined as participant-reported symptoms & objectively observed signs typical of an acute inflammatory demyelinating event in CNS, developing acutely or sub-acutely with duration of at least 24 hours, in absence of fever or infection. Clinical characteristics of number of relapses during last year before enrollment of parent study (it is reported based on retrospective data collection [based on chart review] at study visit 1) in the form of long-term responders & non-responder was reported. Here long term responder is defined as study participants not requiring DMD 4 years or later following their last dose of IMP in parent study. Non-responder is defined as study participants requiring DMD less than 4 years following their last dose of IMP in parent study.	At study visit 1, occurred up to 3 months from screening (Retrospective analysis of medical record of parent study-NCT00213135, NCT00641537 and NCT00725985)
Secondary	Number of Total T1-weighted (T1-W) Lesions	Total number of T1-W lesion were measured by Using magnetic resonance imaging (MRI) Scans.

Non-responder is defined as study participants requiring DMD less than 4 years following their last dose of IMP in parent study.	At study visit 2, within 6 months from screening (Retrospective analysis of medical record of parent study-NCT00213135, NCT00641537 and NCT00725985)
Secondary	Number of Total T2-weighted (T2-W) Lesions	Total number of T2-W lesion were measured by Using magnetic resonance imaging (MRI) Scans. Here long term responder is defined as study participants not requiring DMD 4 years or later following their last dose of IMP in parent study. Non-responder is defined as study participants requiring DMD less than 4 years following their last dose of IMP in parent study.
