Primary Outcome
- Time to First Relapse by Kaplan-Meier EstimatesRelapses are key features of the clinical presentation of multiple sclerosis. Relapses were assessed retrospectively based on clinical records and subject history. Time to first relapse is the difference from date of first relapse to the date of the BENEFIT baseline visit +1 or time to first relapse is the difference from date of last clinical visit to the date of the BENEFIT baseline visit + 1 (right censored).Timeframe: Up to Year 11 (Day 3960)
- Time to Clinically Definite Multiple Sclerosis (CDMS) Represented by Kaplan-Meier EstimatesCDMS could be reached due to a qualifying relapse or sustained progression of 1.5 points on the expanded disability status scale (EDSS) as compared to the lowest EDSS obtained during screening or Day 1 and a total EDSS of >=2.5. The validity of CDMS diagnoses was confirmed by a central committee. The EDSS scale quantifies disability in multiple sclerosis (MS) in 8 functional systems, values vary between 0="normal neurological examination" and 10="death due to MS" measured in half-points on an ordinal scale. Time to CDMS = the difference from date of CDMS to the date of Day 1 + 1 or time to CDMS = the difference from date of last clinical visit to the Day 1+1 (right censored).Timeframe: Up to Year 11 (Day 3960)
- Number of Subjects With Diagnosis of Multiple Sclerosis Within Eleven years after Clinically-Isolated Syndrome (CIS) According to McDonald 2001 and 2010 CriteriaMS according to the criteria by McDonald was reached if, in addition to the single clinical demyelinating event, both dissemination in space (DIS) and dissemination in time (DIT) were established by magnetic resonance imaging (MRI) criteria or a new relapse. Number of subjects with diagnosis of MS within 11 years after CIS according to McDonald 2001 and 2010 criteria were reported.Timeframe: Year 11
- Disease Course as Assessed at the Time of BENEFIT 11Current diagnosis of MS type were categorized with regard to McDonald 2001 and McDonald 2010 criteria were recorded. CIS and silent disease (no relapse, no sustained EDSS progression and no new MRI lesion), McDonald MS not fulfilling the criteria for CDMS, RRMS (CDMS with relapses without evidence for a secondary disease course), SPMS (CDMS with relapses and evidence for a progressive disease course), Revised diagnosis (other reason than MS found for CIS) and Not assessable. Not assessable means McDonald 2001 and McDonald 2010 criteria could not be judged due to missing MRI scan at BENEFIT 11. Number of subjects with current diagnosis of MS at the time of BENEFIT 11 was assessed.Timeframe: Year 11
- Percentage of Subjects Converting to Secondary Progressive Multiple Sclerosis (SPMS)SPMS was defined for this study as progressive deterioration observed and sustained for at least 6 months with or without superimposed attacks. Percentage of subjects converting to SPMS were stratified by actual treatment group and baseline EDSS. Baseline EDSS defined as lowest of the EDSS scores obtained during BENEFIT screening or baseline (less than or equal to [<=] median or greater than [>] median).Timeframe: Year 11
- Time to Secondary Progressive Multiple Sclerosis (SPMS) Represented by Kaplan-Meier EstimatesSPMS was defined for this study as progressive deterioration observed and sustained for at least 6 months with or without superimposed attacks. Time to SPMS was represented by Kaplan-Meier estimates.Timeframe: Up to Year 11 (Day 3960)
- Expanded Disability Status Scale (EDSS) at Year 11The EDSS scale is a method of quantifying disability in multiple sclerosis in eight functional systems and values vary between 0="normal neurological examination" and 10="death due to MS" measured in half-points on a scale. The first levels 1.0 to 4.5 refer to people with a high degree of ambulatory ability and the subsequent levels 5.0 to 9.5 refer to the loss of ambulatory ability. The range of main categories include (0) = normal neurologic exam; to (5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS.Timeframe: Year 11
- Number of Subjects With Confirmed and Sustained 1-point Expanded Disability Status Scale (EDSS) Progression at Year 11The EDSS scale is a method of quantifying disability in multiple sclerosis in eight functional systems and values vary between 0="normal neurological examination" and 10="death due to MS" measured in half-points on a scale. EDSS progression was defined as an increase in the EDSS of at least 1.0 point compared to initial EDSS score or an increase in the EDSS of at least 1.5 points compared to initial EDSS score, if this score was = 0 points. Confirmed EDSS progression status in any of the previous BENEFIT studies (304747, 305207, 311129) was defined as an EDSS progression observed at two consecutive scheduled visits at least 140 days apart from each other. A confirmed EDSS progression is defined as a confirmed EDSS progression in any of the previous BENEFIT studies or EDSS progression in BENEFIT 11. A sustained EDSS progression is defined as a confirmed EDSS progression in any of the previous BENEFIT studies sustained up to and including the BENEFIT 11 visit.Timeframe: Year 11
- Number of Subjects With Confirmed 2.5-point Expanded Disability Status Scale (EDSS) Progression at Year 11The EDSS scale is a method of quantifying disability in multiple sclerosis in eight functional systems and values vary between 0="normal neurological examination" and 10="death due to MS" measured in half-points on a scale. EDSS progression was defined as an increase in the EDSS of at least 2.5 points compared to initial EDSS score, if this score was <= 3.5 points, or an increase in the EDSS of at least 2.0 points compared to initial EDSS score, if this score was > 3.5 points. Confirmed EDSS increase status in any of the previous BENEFIT studies (304747, 305207, 311129) was defined as an EDSS increase confirmed at scheduled visits after at least 140 days. A confirmed EDSS increase is defined as a confirmed EDSS increase in any of the previous BENEFIT studies or EDSS increase in BENEFIT 11.Timeframe: Year 11
- Percentage of Subjects who Ever Reached a Disability Status Scale (DSS) 3 and 6The DSS 3, and DSS 6 are important milestones in the course of disability progression and were documented if reached by the subject.Timeframe: Year 11
- Disability Based Efficacy Domain: Time to Disability Status Scale (DSS) 3 by Kaplan-Meier EstimatesThe DSS 3 is an important milestones in the course of disability progression and were documented if reached by the subject. The time point of reaching DSS 3 was obtained retrospectively in the BENEFIT 11 study. Time to respective DSS is the difference between the date of respective DSS and the date of the BENEFIT baseline visit +1. Subjects without event at BENEFIT 11 were censored at the BENEFIT 11 visit. This constituted a right-censored observation. Cumulative probability of reaching DSS 3 at Year 11 were estimated by Kaplan-Meier.Timeframe: Up to Year 11 (Day 3960)
- Disability Based Efficacy Domain: Time to Disability Status Scale (DSS) 6 by Kaplan-Meier EstimatesThe DSS 6 is an important milestones in the course of disability progression and were documented if reached by the subject. The time point of reaching DSS 6 was obtained retrospectively in the BENEFIT 11 study. Time to respective DSS is the difference between the date of respective DSS and the date of the BENEFIT baseline visit +1. Subjects without event at BENEFIT 11 were censored at the BENEFIT 11 visit. This constituted a right-censored observation. Cumulative probability of reaching DSS 6 at Year 11 were estimated by Kaplan-Meier.Timeframe: Up to Year 11 (Day 3960)
- Multiple Sclerosis Functional Composite (MSFC) at Year 11The MSFC score consists of three subtests (Timed 25 Foot Walk, 9 Hole Peg Test, 3" Paced Auditory Serial Addition Test [PASAT]) whose Z-standardized results (based on baseline values on Day 1 in Study 304747) were combined into a composite score including upper and lower extremities function, and cognitive function. Standardized results (Z-scores) of the subtests and the overall MSFC Z-score as an average of the three Z-scores were derived using baseline data pooled over both treatment arms as reference population. Higher Z-scores reflect a better neurological status.Timeframe: Year 11
- Multiple Sclerosis Severity Score (MSSS) at Year 11The MSSS added the element of disease duration to the EDSS and was designed to provide a measure of disease severity. It was derived from the EDSS during the data evaluation. The MSSS corrects the EDSS for the duration of disease by using an arithmetical method to compare an individual’s disability with the distribution of scores in case of having equivalent disease duration.Timeframe: Year 11
- Cognitive Function: Paced Auditory Serial Addition Test-3 (PASAT-3) at Year 11The Paced Auditory Serial Addition Test (PASAT) is a measure of cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability.Timeframe: Year 11
- Cognitive function: Symbol Digit Modalities Test (SDMT)The Symbol Digit Modalities Test (SDMT) is a cognitive test for sustained attention, concentration, and information-processing speed, with a high sensitivity. Nine different geometrical symbols have one corresponding number each. One-hundred-ten symbols are presented without these numbers; the subject must find the matching number from the top line and verbalize the number to the examiner. The subject is allowed to proceed for 90 seconds, and the number of correct responses in 90 seconds is counted as the total correct score. Also, the numbers of correct responses at 30 and 60 seconds were recorded in this study. Total score ranged from 0 (worst outcome) to best (outcome).Timeframe: Year 11
- Relapse-Based Efficacy domain: Hazard Ratio for Recurrent RelapsesA relapse was defined as the appearance of a new neurological abnormality or the reappearance of a neurological abnormality, separated by at least 30 days from onset of a preceding clinical demyelinating event. The time to the onset of recurrent relapses was determined for each subject according to the counting process representation for recurrent events. Time to a relapse was right censored if a relapse risk period ended without relapse. Based on the Andersen Gill model the hazard ratio for recurrent relapses was estimated with actual treatment in BENEFIT (304747; i.e. IFNB-1b 250 microgram vs. placebo), steroid use during first event (yes vs. no), onset of disease (multifocal vs. monofocal) and number of T2 lesions on BENEFIT screening MRI (categorized as 2-4, 5-8, >=9) included in the model.Timeframe: Year 11
- Relapse Based Efficacy Domain: Annualized Relapse RateThe annualized relapse rate is defined as total number of relapses up to Year 11 divided by the total observation time (last clinical visit minus first day of study treatment administration plus 1 of all subjects) in years.Timeframe: Year 11
- Time to use of Ambulatory Device Represented by Kaplan-Meier EstimatesDate of use of ambulatory device is defined as the retrospectively obtained time point of first use/dependence. Time to use of ambulatory device is the difference between the date of first use/dependence and the date of the BENEFIT baseline visit +1.Timeframe: Up to Year 11 (Day 3960)
- Time to Dependence of Ambulatory Device for Walking Represented by Kaplan-Meier EstimatesDate of dependence from ambulatory device is defined as the retrospectively obtained time point of first use/dependence. Time to dependence from ambulatory device is the difference between the date of first use/dependence and the date of the BENEFIT baseline visit +1. Cumulative probability of dependence of ambulatory device for walking represented by Kaplan-Meier estimates at Year 11.Timeframe: Up to Year 11 (Day 3960)
- Number of Subjects With Wheelchair Use After 11 yearsTimeframe: Year 11

- Patient-Reported Outcomes (PRO)-based Efficacy Domain: Center of Epidemiological Studies Depression Scale (CES-D) Total Score at Year 11The CES-D is a measure of depressive symptomatology. The CES-D was a self-administered questionnaire for adults comprising 20 items which evaluated the frequency and severity of depressive symptoms. Subjects were asked to recall the previous 7 days. The total score (0-60) was the sum of the scores of the 20 items. A score of >= 16 suggested a mild to moderate level of depressive symptoms; a score >21 suggested major depressive symptoms.Timeframe: Year 11
- PRO-based Efficacy Domain: Fatigue Scale for Sensory and Motor Functions (FSMC)The cognitive and physical fatigue was assessed by the FSMC. The scale comprised of 20 questions (10 items for physical and 10 items for cognitive fatigue) and could be completed within 5 minutes. The items are rated on a 5-point Likert scale (1=does not apply at all to 5=applies completely). The FSMC total score ranges from 20 to 100 where a higher score is associated with a higher severity of fatigue.Timeframe: Year 11
- Functional Assessment of Multiple Sclerosis (FAMS) Trial Outcome Index (TOI) at Year 11The Functional Assessment of Multiple Sclerosis (FAMS) instrument is a self-reporting, multi-dimensional, health-related QoL index for use in subjects diagnosed with MS. It comprised 58 items on 7 subscales (mobility, symptoms, emotional well-being, general contentment, thinking and fatigue, family/social wellbeing, and additional concerns). FAMS-TOI is the sum of the subscale scores mobility, symptoms, thinking/fatigue, and additional concerns. The items were rated on a 5-point scale (0 to 4). Score range of FAM-TOI is 0 to 148; the higher the score, the higher the quality of life. The evaluation period was the previous 7 days.Timeframe: Year 11
- Functional Assessment of Multiple Sclerosis (FAMS) Total Score at Year 11The Functional Assessment of Multiple Sclerosis (FAMS) instrument is a self-reporting, multi-dimensional, health-related QoL index for use in subjects diagnosed with MS. It comprised 58 items on 7 subscales: mobility, symptoms, emotional well-being, general contentment, thinking and fatigue, family/social wellbeing, and additional concerns. The items were rated on a 5-point scale (0 to 4). Total score is sum of all sub-scale scores except 14 items for "Additional concerns", ranging 0 to 176; the higher the score, the higher the quality of life. The evaluation period was the previous 7 days.Timeframe: Year 11
- PRO-based Efficacy Domain: European Quality of Life – 5 Dimensions (EQ-5D) Score at Year 11The EQ-5D measured five state-of-health dimensions: mobility, self-care, usual activities (work, leisure, etc.), pain/discomfort, and anxiety/depression. Every item had a score of 1 (no problems), 2 (some/moderate problems), or 3 (extreme problems). An individual’s health status was defined in a combination of 5 digits. Subjects with missing answers to all questions were not considered for the respective visit.Timeframe: Year 11
- European Quality of Life – 5 Dimensions (EQ-5D) Health-related quality of life (HRQoL) Score at Year 11Based on large population surveys, an algorithm was developed to combine the recordings of each of these five EQ-5D dimensions in 1 single HRQoL score, ranging from +1 (best imaginable HRQoL score) to -0.59 (worst imaginable HRQoL score). A relatively higher score represents better quality of life.Timeframe: Year 11
- Number of Subjects who Started Second Line Therapy at Year 11Subjects were treated exclusively at the discretion of their treating physician and according to locally applicable standards and treatment guidelines. Subjects received second line therapy as a MS treatment such as alemtuzumab, cyclophosphamide, ciclosporin, fingolimod, methotrexate, mycophenolate mitoxantrone, natalizumab, etc.Timeframe: Year 11
- Number of Subjects who Started First Disease-Modifying Treatment (DMT) other than IFNB at Year 11Subjects were treated exclusively at the discretion of their treating physician and according to locally applicable standards and treatment guidelines. All DMTs other than interferon beta, interferon beta-1a and interferon beta-1b were recorded as DMT other than IFNB.Timeframe: Year 11
- Magnet-Resonance Imaging (MRI): Number of Newly Active LesionsContrast-enhanced MRI (with an extracellular gadolinium-based contrast agent) technique was used for the evaluation of brain lesions in MS. Newly active lesions defined as displaying either new enhancement on T1-weighted scans, or non-enhancing on T1-weighted scan but new on T2-weighted scans.Timeframe: Year 11
- Magnet-Resonance Imaging (MRI): Number of Lesions on T1- and T2-Weighted ScansContrast-enhanced MRI (with an extracellular gadolinium-based contrast agent) technique was used for the evaluation of brain lesions in MS. Number of lesions on T1- and T2-Weighted scans were recorded.Timeframe: Year 11
- Magnet-Resonance Imaging (MRI): Volume of Lesions on T1- and T2-Weighted ScansContrast-enhanced MRI (with an extracellular gadolinium-based contrast agent) technique was used for the evaluation of brain lesions in MS. Volume of lesions on T1- and T2-Weighted scans were recorded.Timeframe: Year 11
- Magnet-Resonance Imaging (MRI): Normalized Brain VolumeContrast-enhanced MRI (with an extracellular gadolinium-based contrast agent) technique was used for the evaluation of brain lesions in MS. Brain volume was analysed and reported.Timeframe: Year 11
- Optical Coherence Tomography (OCT) Parameter - Retinal Nerve Fiber Layer (RNFL)OCT is a noninvasive ocular imaging recognized in MS as a marker of axonal loss. Retinal nerve fiber layer (RNFL) thinning measured by OCT in subjects with MS occurs even in the absence of acute optic neuritis and is associated with worse scores for low-contrast letter acuity and other visual acuity tests. OCT measures peripapillary RNFL.Timeframe: Year 11
- Optical Coherence Tomography (OCT) Parameter - Total Macular Volume (TMV)OCT is a noninvasive ocular imaging recognized in MS as a marker of axonal loss. OCT is a potential method for capturing neuronal in addition to axonal degeneration in MS.Timeframe: Year 11
- Optical Coherence Tomography (OCT) Parameter - Pupillo Macular Bundle (PMB)OCT is a noninvasive ocular imaging recognized in MS as a marker of axonal loss. OCT is a potential method for capturing neuronal in addition to axonal degeneration in MS.Timeframe: Year 11
- Optical Coherence Tomography (OCT) Parameter – Ganglion Cell Inner Plexiform LayerOCT is a noninvasive ocular imaging recognized in MS as a marker of axonal loss. OCT is a potential method for capturing neuronal in addition to axonal degeneration in MS.Timeframe: Year 11
- Ophthalmological examination – Optic Nerve HeadStandard clinical ophthalmic examination and test were applied for visual assessment and the differential diagnosis of OCT-related findings.Timeframe: Year 11
- Ophthalmological examination - Slit lamp BiomicroscopyStandard clinical ophthalmic examination and test were applied for visual assessment and the differential diagnosis of OCT-related findings. Ocular medical and surgical history, visual acuity (Early Treatment Diabetic Retinopathy Study Chart), low-contrast letter acuity (Sloan charts), and eye examination through slit-lamp biomicroscopy were assessed.Timeframe: Year 11
- Ophthalmological examination - Visual AcuityStandard clinical ophthalmic examination and test were applied for visual assessment and the differential diagnosis of OCT-related findings. Ocular medical and surgical history, visual acuity (Early Treatment Diabetic Retinopathy Study Chart), low-contrast letter acuity (Sloan charts), and eye examination through slit-lamp biomicroscopy were assessed.Timeframe: Year 11
- Number of Subjects with Vitamin D IntakeNumber of subjects with intake of Vitamin D were categorized as, 'since beginning of the BENEFIT study', and 'within the past 12 months'.Timeframe: Year 11
