Efficacy and Safety of Rimegepant for Migraine Patients: A Meta-analysis of Randomized Controlled Studies

Objectives Rimegepant may have some potential in treating migraine, and this meta-analysis aims to study the efficacy and safety of rimegepant for migraine patients. Methods We have searched several databases including PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases and selected the randomized controlled trials comparing the efficacy of rimegepant versus placebo for migraine patients. This meta-analysis was conducted using the random- or fixed-effect model based on the heterogeneity. Results Three randomized controlled trials were included in this meta-analysis. Compared with placebo in migraine patients, rimegepant treatment was associated with substantially improved freedom from pain at 2 hours (odds ratio [OR], 2.10; 95% confidence interval [CI], 1.69–2.59; P < 0.00001), pain relief at 2 hours (OR, 1.93; 95% CI, 1.65 to 2.25; P < 0.00001), freedom from the most bothersome symptom at 2 hours (OR, 1.61; 95% CI, 1.35–1.91; P < 0.00001), ability to function normally at 2 hours (OR, 1.69; 95% CI, 1.42–2.01; P < 0.00001), sustained freedom from pain at 24 hours (OR, 2.88; 95% CI, 1.74–4.78; P < 0.0001), sustained pain relief at 24 hours (OR, 2.31; 95% CI, 1.96–2.72; P < 0.00001), and no rescue medication (OR, 2.42; 95% CI, 2.02–2.90; P < 0.00001) but showed no obvious impact on adverse events (OR, 1.27; 95% CI, 1.01–1.60; P = 0.04). Conclusions Rimegepant may be effective and safe for the treatment of migraine patients.
