Objective

Background BACKGROUND: Dimethyl fumarate demonstrated an acceptable safety profile in Phase 3 studies. Common AEs associated with dimethyl fumarate included flushing and GI events. Most patients reported GI events that were mild/moderate in severity and decreased substantially in incidence after the first month of treatment.

Design/Methods DESIGN/METHODS: Incidence, nature, severity, and management of GI AEs (by manual review of concomitant medications' indications and timing versus AEs) were summarized for dimethyl fumarate 240 mg BID versus placebo in DEFINE and CONFIRM, focusing on Months 0-3 (when GI AE incidence was highest).

Results RESULTS: A total of 769 patients received dimethyl fumarate and 771 received placebo with 70% and 65% completing 2 years of treatment, respectively. GI AEs were reported by 40% versus 31% patients overall, and 41% versus 34% patients who completed 2-year treatment in dimethyl fumarate and placebo groups, respectively (sensitivity analysis). Within the first 3 months of treatment with dimethyl fumarate, the most common (?5% patients) events were abdominal/upper abdominal pain, nausea/vomiting, and diarrhea. Of the abdominal/upper abdominal pain, nausea/vomiting, and diarrhea events, 91%, 95%, 96% were mild/moderate, <1%,1%,1% resulted in treatment discontinuation, 93%, 95%, 96% resolved within 3 months, and 38%, 33%, 26% utilized symptomatic therapy, respectively. Common symptomatic therapies for abdominal/upper abdominal pain were omeprazole, paracetamol, ranitidine; nausea/vomiting were metoclopramide, domperidone; and diarrhea was loperamide (efficacy not assessed).

Conclusions CONCLUSIONS: The incidence of GI AEs was highest in the first 3 months of treatment (most commonly abdominal/upper abdominal pain and nausea/vomiting, and diarrhea). Most events were mild-to-moderate in severity and resolved within the first 3 months while few GI events resulted in treatment discontinuation. Further studies are needed to evaluate the efficacy of individual management strategies.
