A Study Evaluating the Effectiveness of Tecfidera (Dimethyl Fumarate) on Multiple Sclerosis (MS) Disease Activity and Patient-Reported Outcomes

Phase 4CompletedNCT01930708

Biogen1,114 enrolled

Overview

The primary objective of the study is to estimate the annualized relapse rate (ARR) in participants with Relapsing Remitting Multiple Sclerosis (RRMS) who are treated with dimethyl fumarate (DMF) over a 12-month period. The secondary objectives of this study in this population are to assess the impact of DMF over a 12-month period on participants -reported health-related quality of life (HRQoL) outcomes, additional clinical effectiveness outcomes, and health economics-related outcomes, and to characterize participants-reported adherence to DMF.

Key Inclusion Criteria: * Have a diagnosis of Relapsing-Remitting Multiple Sclerosis (RRMS) and satisfy the approved therapeutic indication for DMF (per the local DMF product information). * Must be naïve to DMF, Fumaderm®, and other compounded fumarates, and to MS therapies that are primarily prescribed second-line (e.g., natalizumab, fingolimod) and to alemtuzumab. * Have a recent complete blood count (CBC) that does not preclude the subject's participation in the study, in the judgment of the Investigator. Key Exclusion Criteria: * Are unwilling or unable to comply with study requirements, or are deemed unsuitable for study participation as determined by the Investigator. * Have major comorbid conditions that preclude participation in the study, as determined by the Investigator. * Are pregnant, unless DMF is clearly needed and the potential benefit of DMF to the subjects justifies the potential risk to the fetus, in the judgment of the Investigator (in all countries except Austria). In Austria, pregnant subjects are excluded from participation in the study. * Are women of childbearing potential and are not using appropriate contraception (per the local DMF product information) as determined by the Investigator. * Women who are breastfeeding may be excluded (per the local DMF product information) at the discretion of the Investigator. * Have previously received or are receiving treatment with MS therapies primarily used second-line (e.g., natalizumab, fingolimod) or alemtuzumab, or are currently receiving and planning to continue on other disease-modifying therapies for RRMS. * Are hypersensitive to the active ingredient in the DMF drug product (i.e., DMF) or to any of the excipients listed in the local DMF product information. * Current enrollment in any clinical trial except for the Biogen Idec DMF Pregnancy Exposure Registry or other studies that, according to the study Medical Director, do not conflict with this study (e.g., health economics studies or local registries). Other protocol-defined inclusion/exclusion criteria may apply.

Outcomes

Primary Outcomes

Annualized Relapse Rate (ARR)

Time frame: 12 Months

Secondary Outcomes

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

This is a validated, 29-item, MS-specific HRQoL scale that measures the physical (20 items) and psychological (9 items) impact of MS on the participant's day-to-day life during the previous 2 weeks. For each item, the subject is asked to circle the number that best describes his or her situation. The numbers for each item range from 1 (not at all) to 5 (extremely).

Time frame: 12 Months

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

This scale consists of 5 statements that describe how fatigue may affect a person. For each statement, the participant is asked to circle the number that best indicates how often fatigue has affected him or her during the previous 4 weeks. The numbers for each question range from 0 (never) to 4 (almost always).

Time frame: 12 Months

Change from Baseline in Treatment Satisfaction Questionnaire for Medication (TSQM) score

This is a validated, 14-item questionnaire that measures a participant's level of satisfaction/dissatisfaction with medication.

Time frame: 12 Months

Change from Baseline in EQ-5D 5 level version (EQ-5D-5L) index

The widely validated EQ-5D includes 2 components, the EQ-5D descriptive system and the EQ VAS. The EQ-5D descriptive system provides a profile of the participant's health state in 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). For each dimension, the subject is instructed to indicate whether he or she has "no problems" (level 1), "slight problems" (level 2), "moderate problems" (level 3), "severe problems (level 4), or "extreme problems/inability" (level 5) on that day. For the EQ VAS, the participant is instructed to mark an "x" on a vertical scale at the point that best describes his or her own health on that day, where 0 represents the "worst health" he or she can imagine and 100 the "best health" he or she can imagine.

Time frame: 12 Months

Change from Baseline in participants-Reported Indices for Multiple Sclerosis-Activity Limitations (PRIMUS-Activity Limitations) score

This 15-item component of the PRIMUS assesses a participant's ability to carry out various activities of daily living during the previous week without the use of aids (e.g., cane, walker, or wheelchair) or assistance. For each item, the participant is asked whether he or she can perform the activity without difficulty or with difficulty, or is unable to perform the activity.

Time frame: 12 Months

Change from Baseline in Work Productivity and Activity Impairment-Multiple Sclerosis version (WPAI-MS) score

This 6-item instrument assesses employment status, and, during the previous 7 days, hours of missed work due to MS or other reasons, hours worked (if employed), effect on productivity due to MS while working, and activity impairment attributable to health problems.

Time frame: 12 Months

Change from Baseline in Beck Depression Inventory-Fast Screen (BDI-Fast Screen) score

This is a 7-item scale that evaluates depression in participants with medical illness during the prior 2 weeks. It has been validated in subjects with MS.

Time frame: 12 Months

Proportion of participants with confirmed (24-week) Expanded Disability Status Scale (EDSS) progression

The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist.

Time frame: 12 Months

Annualized Relapse Rate (ARR) at Baseline (i.e., over the 12 months prior to enrollment) and at Month 6

Time frame: Baseline, 6 Months

The proportion of participants relapsed

Time frame: 12 Months

Number of participants who are hospitalized/have emergency room visits due to MS relapses or have relapses requiring intravenous (IV) steroid treatment during the study, or who make visits to neurologists/other specialists due to MS

Time frame: 12 Months

Proportion of participants who are hospitalized/have emergency room visits due to MS relapses or have relapses requiring intravenous (IV) steroid treatment during the study, or who make visits to neurologists/other specialists due to MS

Proportion of participants who report taking the prescribed DMF dose

Time frame: 12 Months

Percentage of participants who report taking the prescribed DMF dose

Time frame: 12 Months

Reasons reported by participants for not taking prescribed DMF dose

Time frame: 12 Months

Change from baseline in EQ Visual Analog Scale (EQVAS) score

A component of the EQ-5D, where participants are asked to rate their overall health-related quality of life on a standard vertical 20 cm visual analogue scale (similar to a thermometer) between 100 (best health imaginable) and 0 (worst health imaginable).

Time frame: 12 Months
