About this study
Prospective, single-site, open-label, non-controlled pilot study consisting of two parallel trials. Participants will receive rimegepant or zavegepant for acute migraine treatment during a single Emergency Department visit, with post-discharge follow-up through 28 days. Participants will be allocated to either the rimegepant trial or the zavegepant trial. The study design does not include a placebo or active comparator control group, and the two gepant study drugs are not designed to function as active comparator groups. The objective in this investigation is to examine relief from either rimegepant or zavegepant in separate parallel trials.
