A Multicenter, Double- Blind, Placebo- Controlled Study of Montelukast on Gastrointestinal Tolerability in Patients With Relapsing Forms of Multiple Sclerosis Receiving Tecfidera® (Dimethyl Fumarate) Delayed Release Capsules

The primary objective of this study is to evaluate whether montelukast can reduce the
severity of gastrointestinal (GI) events, measured by the Gastrointestinal Symptom Rating
Scale (GSRS), after oral administration of dimethyl fumarate (DMF) in participants with
relapsing forms of Multiple Sclerosis (MS). The secondary objectives of this study are as
follows: To evaluate whether montelukast after oral administration of DMF in participants
with relapsing forms of MS decreases discontinuations due to GI events and reduces the number
of participants taking symptomatic therapies for GI events; To investigate the effect of
montelukast on the incidence of flushing events after oral administration of 240 mg DMF in
participants with relapsing forms of MS.


Key Inclusion Criteria:

- Reside in the United States and have a confirmed diagnosis of a relapsing form of MS
and satisfy the therapeutic indication as described in the local label

- As perceived by the Investigator, have the ability to comply with all requirements of
the study protocol and to operate the eDiary required to record GI-related events

- Female participants of childbearing potential who are not surgically sterile must
practice effective contraception during their participation in the study and be
willing and able to continue contraception for 30 days after they complete or withdraw
from the study. All men must practice effective contraception, and they should not
donate sperm throughout the study and for at least 90 days after their last dose of
study treatment.

Key Exclusion Criteria:

- History of significant GI disease (for example, irritable bowel disease, peptic ulcer
disease, history of major GI surgery, eosinophilic GI disease, or food allergies)

- Chronic use (≥7 consecutive days) of bismuth subsalicylate, simethicone, calcium
carbonate, loperamide, proton-pump inhibitors, or ondansetron within 1 month prior to
the Screening Visit

- Use of the following medications: montelukast, immunotherapy, mast cell stabilizers,
or parenteral, inhaled, or oral steroids up to 1 month prior to the Screening Visit.
Use of these medications is also not permitted for the duration of the study (except
for the use of montelukast as per study protocol) and will lead to discontinuation

- Have one or more major comorbidities that, in the opinion of the Investigator, may
affect the outcome of the study

- History of malignancy (except for basal cell carcinoma that had been completely
excised prior to study entry), severe allergic or anaphylactic reactions or known drug
hypersensitivity, abnormal laboratory results indicative of any significant disease,
and/or a major disease that would preclude participation in a clinical study
