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

|Official Title:||A Multicenter, Open-Label Study Evaluating the Effectiveness of Oral Tecfidera™ (Dimethyl Fumarate) on MS Disease Activity and Patient-Reported Outcomes in Subjects With Relapsing-Remitting Multiple Sclerosis in the Real-World Setting|
- Annualized Relapse Rate (ARR) [ Time Frame: 12 Months ]
- Change from Baseline in Multiple Sclerosis Impact Scale (MSIS-29) score [ Time Frame: 12 Months ]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).
- Change from Baseline in Modified Fatigue Impact Scale-5 Item (MFIS-5) score [ Time Frame: 12 Months ]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).
- Change from Baseline in Treatment Satisfaction Questionnaire for Medication (TSQM) score [ Time Frame: 12 Months ]This is a validated, 14-item questionnaire that measures a participant's level of satisfaction/dissatisfaction with medication.
- Change from Baseline in EQ-5D 5 level version (EQ-5D-5L) index [ Time Frame: 12 Months ]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.
- Change from Baseline in participants-Reported Indices for Multiple Sclerosis-Activity Limitations (PRIMUS-Activity Limitations) score [ Time Frame: 12 Months ]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.
- Change from Baseline in Work Productivity and Activity Impairment-Multiple Sclerosis version (WPAI-MS) score [ Time Frame: 12 Months ]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.
- Change from Baseline in Beck Depression Inventory-Fast Screen (BDI-Fast Screen) score [ Time Frame: 12 Months ]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.
- Proportion of participants with confirmed (24-week) Expanded Disability Status Scale (EDSS) progression [ Time Frame: 12 Months ]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.
- 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 [ Time Frame: 12 Months ]
- 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 [ Time Frame: 12 Months ]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).
