Biogen

Overview

The primary objective of the study is to evaluate, in participants with RMS, safety and tolerability (as defined by the frequency of adverse events \[AEs\] of flu-like symptoms \[FLS; chills, pyrexia, myalgia, and asthenia\], injection site reactions \[ISRs\], and injection site reaction pain \[ISR-P\]) over 6 months of treatment (the active comparator period) with BIIB017 125 μg subcutaneously (SC) every 2 weeks versus standard-of-care SC interferon-beta (IFN-β) therapy. Secondary objectives of this study are to assess the following measures during the first (6-month) period of the study in participants treated with BIIB017 versus standard-of-care SC IFN-β therapy: patient-reported treatment satisfaction using the following patient-reported outcome measures (PROMs): Treatment Satisfaction Questionnaire for Medication (TSQM-9), Adapted MS Treatment Concerns Questionnaire (MSTCQ), Adapted MSTCQ Side Effects Score, Pain using a visual analog scale (VAS) diary and the McGill Pain Questionnaire Short Form (SF-MPQ), the treatments' impact on RMS using the following PROMs: Multiple Sclerosis Impact Scale (MSIS-29), Modified Fatigue Impact Scale-5 Item (MFIS-5), EuroQol Group 5-Dimension 3-Level Version (EQ-5D-3L), Health-Related Productivity Questionnaire (HRPQ), Beck Depression Inventory, second edition (BDI-II), participant adherence to study treatment, clinical status as measured by the Expanded Disability Status Scale (EDSS) and relapse activity, safety and tolerability of study treatment after a change in standard-of-care SC IFN-β therapy and the immunogenicity profiles of participants changing from standard-of-care SC IFN-β to BIIB017.

Medical Language ↔ Plain English

Key Inclusion Criteria: * Must have a confirmed diagnosis of Relapsing Multiple Sclerosis (RMS), as defined by McDonald criteria. * An Expanded Disability Status Scale (EDSS) score between 0 and 5.0. * On continual treatment for ≥6 months with a single standard-of-care subcutaneous (SC) interferon beta (IFN-β) therapy, including IFN β-1b 0.25 mg SC every other day or IFN β-1a 44 μg SC 3 times weekly, and from a clinical perspective be able to continue this therapy (i.e., no significant untoward events attributed to IFN therapy that would preclude continuation of the existing IFN therapy). * A candidate for change to BIIB017 therapy (candidacy for therapy change is determined by the treating physician; however, it is recommended to exclude patients with high disease activity and who are candidates for escalation therapy according to local guidelines). * Patients who are randomized to their current standard-of-care IFN-β therapy for the first 6 months of the study must be willing to receive their treatment via the formulation provided in the study (i.e., Rebif 44 μg in a prefilled syringe or Betaferon/Betaseron 0.25 mg in single-use vials of lyophilized powder accompanied by a prefilled single-use diluent syringe). Key Exclusion Criteria: * Primary progressive, secondary progressive, or progressive relapsing MS. * History of inadequate response to SC IFN therapy (as determined by the treating physician). * History of severe allergic or anaphylactic reactions or known hypersensitivity to study drug or its excipients. - Known allergy to any component of the BIIB017 formulation. * History of any clinically significant (as determined by the Investigator) cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal, or other major disease that would preclude participation in a clinical study. * History of hypersensitivity or intolerance to acetaminophen, ibuprofen, naproxen, or aspirin that would preclude use of at least one of these during the study. * An MS relapse that has occurred within the 50 days prior to randomization and/or lack of stabilization from a previous relapse prior to randomization. * Any previous treatment with BIIB017. * Treatment with other agents for MS. NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

Outcomes

Primary Outcomes

Combined Counts of adverse events (AEs) of flu-like symptoms, injection site reactions or injection site reaction pain

Combined counts of AEs of flu-like symptoms (FLS) including chills, pyrexia, myalgia, and asthenia, injection site reactions (ISRs), and injection site reaction pain (ISR-P) over the first 6 months of treatment.

Time frame: 6 Months

Secondary Outcomes

Change from Baseline in treatment satisfaction using the Treatment Satisfaction Questionnaire for Medication-9 Items (TSQM-9)

The TSQM-9 is a 9-item, validated questionnaire that assesses participants' satisfaction with treatment and captures information on treatment effectiveness, convenience, and overall satisfaction.

Time frame: Baseline and Week 24

Change from Baseline in adapted Multiple Sclerosis Treatment Concerns Questionnaire (MSTCQ) total score

The adapted MSTCQ self-administered questionnaire includes evaluation of the injection process, treatment differences, overall injection issues, FLS, and ISRs.

Time frame: Baseline and Week 24

Change from Baseline in the adapted MSTCQ Side Effects Score

Time frame: Baseline and Week 24

Percentage of participants pain-free

Pain free is defined as a score of 0 for all full-dose injections measured on a visual analog scale (VAS) diary of patient-reported pain. The scale ranges from 0 (no pain) to 10 (worse possible pain).

Time frame: 6 months

Change from Baseline in mean change in VAS pain score from pre-injection to 30 minutes post-injection

Pain was measured on a visual analog scale (VAS) prior to injection and 30 minutes after injection. The VAS scale ranges from 0 (no pain) to 10 (worse possible pain).

Time frame: Baseline (pre-injection and 30-minutes after injection) and Week 24 (pre-injection and 30 minutes after injection)

Change from Baseline in mean McGill Pain Questionnaire Short Form (SF-MPQ) VAS pain score

This self-administered questionnaire provides qualitative measures of clinical pain that captures its sensory, affective, and other qualitative components.

Time frame: Baseline and Week 24

Change from Baseline in the Multiple Sclerosis Impact Scale-29 items (MSIS-29) score

The MSIS-29 is a self-report questionnaire measuring the physical (20 items) and psychological (9 items) impact of MS from the patient's perspective. Each of the 29 questions can take 1 of 5 responses, ranging from 1 (not at all) to 5 (extremely). Combined scores for MSIS-29 scales are generated by summing items, with a total score ranging from 29 to 145.

Time frame: Baseline and Week 24

Change from Baseline in the Modified Fatigue Impact Scale-5 Item (MFIS-5) score

The MFIS-5 is a structured, self-report questionnaire, modified from the Fatigue Impact Scale. The abbreviated version (MFIS-5) has 5 items taken from the physical (2 items), cognitive (2 items), and psychological (1 item) subscales of the standard 21-item MFIS. The participant is asked to score each item from 0 to 4. All items are scaled so that higher scores indicate a greater impact of fatigue on a participant's activities. The MFIS-5 total score consists of the sum of the raw scores on the 5 items, and thus can range from 0 to 20.

Time frame: Baseline and Week 24

Change from Baseline in the EuroQol-5-dimension 3-level version (EQ-5D-3L) index

The EQ-5D-3L is a descriptive system of health-related quality-of-life states consisting of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each of which can take 1 of 3 responses. The responses record 3 levels of severity (no problems/some or moderate problems/extreme problems) within a particular EQ-5D dimension.

Time frame: Baseline and Week 24

Change from Baseline in the Health-Related Productivity Questionnaire (HRPQ) score

This self-administered questionnaire provides information about absenteeism and presenteeism over the previous week and includes an estimate of unproductive work time.

Time frame: Baseline and Week 24

Change from Baseline in the Beck Depression Inventory, second edition (BDI-II) score

BDI-II is a 21-item self-administered questionnaire to assess the intensity of depression.

Time frame: Baseline and Week 24

Percentage of participants with changes in Clinical Status assessed using the Expanded Disability Status Scale (EDSS)

The EDSS is a method of quantifying disability in MS. The EDSS is an ordinal clinical rating scale based on a standard neurological exam, with scores ranging from 0 (normal neurological exam) to 10 (death due to MS) in half-point increments.

Time frame: Up to 6 months

Annualized relapse rate (ARR)

The ARR is calculated by dividing the number of relapses the participants experience during a 1-year period by the number of participants.
