Brief summary
The primary objective of this study is to evaluate the long-term safety and tolerability of peginterferon beta-1a (BIIB017) in participants originally treated in Study 105MS301 (NCT00906399) who continue peginterferon beta-1a treatment. The secondary objective of this study is to describe long-term multiple sclerosis (MS) outcomes in participants originally treated in Study 105MS301 (NCT00906399) who continue peginterferon beta-1a treatment.

Pre-assignment details
Participants continued BIIB017 at the same dosage regimen they were following during treatment year 2 of Study 105MS301: BIIB017 125 μg subcutaneously (SC) every 2 weeks (Q2W) or every 4 weeks (Q4W). A major change in study design was introduced in Amendment 3 of the protocol, which switched all ongoing subjects dosing Q4W to dosing Q2W.

Annualized Relapse Rate (ARR)
Relapses are defined as new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the examining neurologist. The annualized relapse rate is calculated as the total number of relapses occurred during the period for all participants, divided by the total number of person-years followed in the period.
Time frame: up to 4 years
Population: ITT population: all participants who were assigned a treatment and received at least 1 dose of study treatment.

Change From Baseline in 12-Item Short Form Health Survey (SF-12) Mental Component Score (MCS)
The SF-12 is a multipurpose short form survey with 12 questions, all selected from the SF-36 Health Survey. The questions were combined, scored, and weighted to create two scales that provide glimpses into mental and physical functioning and overall health-related-quality of life. MCS computed using the scores of 12 questions and range from 0 to 100, where a 0 score indicates the lowest level of health and 100 indicates the highest level of health. Observed data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

Change From Baseline in EQ-5D Visual Analogue Scale (VAS)
The EQ-5D VAS records the participant's self-rated health on a scale from 0-100 where 100 is the 'best imaginable health state' and 0 is the 'worst imaginable health state.' The scale was normalized to a scale of 0 to 1, with higher values indicating a better health state. Observed data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

Change From Baseline in Euro Quality of Life (EQ-5D) Index Score
The EQ-5D is a participant-answered questionnaire scoring 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Scores of 1, 2, or 3 are possible responses for each of 5 questions (1=no problems, 2=some problems, 3=severe problems). A scoring formula developed by the EuroQol Group is then used to assign utility values for each participant's Health State Profile. A summary index score (EQ-5D index score) is derived from the 5 questions by conversion with this scoring formula and a table of scores. EQ-5D Summary Index values ranged from -0.6 (worst health state) to 1.00 (perfect health state). Observed data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

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. Data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

Change From Baseline in Multiple Sclerosis Impact Scale (MSIS)-29 Physical Score
The 29-item MSIS-29 is a disease-specific participant-reported outcome measure that has been developed and validated to examine the physical and psychological impact of MS from a patient's perspective; it measures 20 physical items and 9 psychological items. Responses use a 5-point Likert scale ranging from 1 to 5. All questions are to be answered. The physical well being assessment portion of the MSIS-29 consists of 20 questions in which participants rate the impact of MS on their day-to-day life during the past two weeks from 1=no impact to 5=extreme impact for a total score of 20-100. A lower total score indicates less physically-related impact while a higher total score indicates greater physically-related impact on a participant's functioning. Observed data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

Change From Baseline in SF-12 Physical Component Score (PCS)
The SF-12 is a multipurpose short form survey with 12 questions, all selected from the SF-36 Health Survey. The questions were combined, scored, and weighted to create two scales that provide glimpses into mental and physical functioning and overall health-related-quality of life. PCS was computed using the scores of 12 questions and range from 0 to 100, where a 0 score indicates the lowest level of health and 100 indicates the highest level of health. Observed data after participants switched to alternative MS medications or after Amendment 3 took effect are excluded.

Time to Sustained Disability Progression
Estimated proportion of participants with progression and time to progression based on the Kaplan-Meier product limit method. Sustained disability progression is defined as: at least a 1.0 point increase on the EDSS from 105MS302 baseline EDSS ≥ 1.0 that is sustained for 24 weeks, or at least a 1.5 point increase on the EDSS from 105MS302 baseline EDSS = 0 that is sustained for 24 weeks. The EDSS measures the disability status of people with multiple sclerosis on a scale that ranges from 0 to 10. 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. Participants were censored at the time of withdrawal/switch/A3 effective date if they withdrew from study, switched to alternative MS medication, or Amendment 3 took effect without a progression.
Time frame: Weeks 12, 24, 28, 72, 96, 120, 144, 168
Population: Participants in the ITT population (all participants who were assigned a treatment and received at least 1 dose of study treatment) with disability progression.
