Phase 4 Gastrointestinal Tolerability Study of Dimethyl Fumarate in Patients With Relapsing Forms of Multiple Sclerosis in the United States
Phase 4 Gastrointestinal Tolerability Study of Dimethyl Fumarate in Patients With Relapsing Forms of Multiple Sclerosis in the United States
The primary objective of this study is to evaluate the effect of symptomatic therapies on
 gastrointestinal (GI)-related events reported by participants with relapsing forms of
 multiple sclerosis (MS) initiating therapy with dimethyl fumarate (DMF) in the clinical
 practice setting.

 The secondary objectives of this study are as follows:

 -  To evaluate GI-related events requiring symptomatic therapy and the role of those
 therapies over time in participants with relapsing forms of MS initiating therapy with
 DMF in the clinical practice setting.

 -  To evaluate GI-related events that lead to DMF discontinuation after the use of
 symptomatic therapy in participants with relapsing forms of MS initiating therapy with
 DMF in the clinical practice setting.
Key Inclusion Criteria:

 -  Decision to treat with DMF must precede enrollment.

 -  Naïve to DMF or fumaric acid esters.

 -  Resides in the US and has a confirmed diagnosis of a relapsing form of MS.

 -  Satisfies the approved therapeutic indication(s) for DMF.

 Key Exclusion Criteria:

 -  Inability to comply with study requirements or, at the discretion of the Investigator,
 is deemed unsuitable for study participation.

 -  History of significant GI disease, chronic use of GI symptomatic therapy, active
 malignancies.

 -  Is participating in any other interventional clinical trial.

 NOTE: Other protocol-defined inclusion/exclusion criteria may apply.
