Study of Diroximel Fumarate in the Real-World Setting

Terminated
Conditions
Relapsing Forms of MS
Interventions
Registration Number
NCT04746976
Lead Sponsor
Biogen
Brief Summary

The primary objective of the study is to characterize the persistence to therapy in participants with relapsing forms of multiple sclerosis (RMS) treated with diroximel fumarate (DRF) in routine clinical practice. The secondary objectives of the study are to assess short-term persistence to treatment; to assess long-term persistence on treatment; to assess the effect of DRF on relapses; to assess the impact of DRF on cognition; to assess the impact of DRF on participant reported outcomes (PROs) and to explore the real-world safety profile of DRF (ie, gastrointestinal \[GI\] tolerability, lymphocyte dynamics, adverse events \[AEs\] leading to discontinuation, and serious adverse events \[SAEs\]).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants on Treatment with DRF at 1 Year1 year
Secondary Outcome Measures
NameTimeMethod
Percentage of Participants on Treatment with DRF at 3 Months3 months
Change in Processing Speed Test (PST) Score from BaselineBaseline up to 2 years

PST measures mental processing speed. The PST will be assessed using multiple sclerosis performance test (MSPT). The participants will be shown some symbols and corresponding numbers. The participants will be then asked to input the numbers corresponding to the given symbols in empty rows. Higher number of correct responses indicates better cognition

Change in Disability, as Measured by Patient Determined Disease Steps (PDDS)Baseline up to 2 years

The PDDS has nine ordinal levels ranging between 0 (normal) and 8 (bedridden). Higher scores indicate greater disability.

Percentage of Participants on Treatment with DRF at 2 Years2 years
Change in Score for Each Domain of Quality of Life in Neurological Disorders (Neuro- QoL™) QuestionnaireBaseline up to 2 years

Neuro-QOL uses a T score which has a mean of 50 and SD of 10, based on the norming sample used. All Neuro-QOL banks and scales are scored such that a high score reflects more of what is being measured.

Annualized Relapse Rate (ARR) with DRFAt 1 and 2 years
Percentage of Participants RelapsedAt 1 and 2 years
Number of Participants categorized by the types of actions taken to mitigate GI AEsUp to 32 months

The actions taken will include temporary dose reduction, temporary dose interruption, initiation of concomitant GI medication, taking DRF dose with food, permanent discontinuation, or other action.

Change in Work Productivity and Activity Impairment Due to Multiple Sclerosis (WPAI- MS) Scores from BaselineBaseline up to 2 years

The Work Productivity and Activity Impairment (WPAI) questionnaire is a validated instrument to measure impairments in work and activities. The WPAI yields four types of scores: 1. Absenteeism (work time missed) 2. Presenteesism (impairment at work / reduced on-the-job effectiveness) 3. Work productivity loss (overall work impairment / absenteeism plus presenteeism) 4. Activity Impairment. Higher numbers indicate greater impairment and less productivity.

Number of Participants with Serious Adverse Events (SAEs)Up to 32 months

An SAE is any untoward medical occurrence that at any dose results in death, in the view of the investigator, places the participant at immediate risk of death, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect or is a medically important event.

Percent Change in Median ALC from BaselineBaseline up to 2 years
Number of Participants with Lymphopenia According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI/CTCAE)Severity GradingUp to 32 months
Number of Participants with Gastrointestinal (GI) Adverse Events (AEs)Up to 32 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal assessment such as an abnormal laboratory value), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Number of Participants with AEs Leading to Treatment DiscontinuationUp to 32 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal assessment such as an abnormal laboratory value), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
