Rimegepant for acute treatment of migraine in triptan-unsuitable adults: A randomized, double-blind, placebo-controlled phase 4 trial
Abstract
Background A subset of individuals with migraine are unsuitable for triptans due to intolerance, lack of efficacy, or contraindications. This phase 4 study assessed the efficacy and tolerability of a single 75-mg dose of rimegepant orally disintegrating tablet (ODT) for acute treatment of migraine in adults with documented triptan unsuitability. Methods Participants (aged ≥18 years with 4–14 migraine days per month) with documented history of (A) intolerance and/or lack of efficacy to ≥2 triptans or (B) contraindication to triptans were randomized (1:1) to rimegepant 75 mg ODT or placebo to treat a single migraine attack of moderate or severe pain intensity. Randomization was stratified by history of clinically relevant cardiovascular disease. The primary endpoint was the percentage of participants with migraine pain relief (no or mild pain) at 2 h post dose. Key secondary endpoints, tested using a hierarchal approach to control type 1 error, included the percentage of participants with migraine pain freedom at 2 h, rescue medication use within 24 h, return to normal function at 2 h, sustained return to normal function from 2–24 h and from 2–48 h, sustained migraine pain relief from 2–24 h and from 2–48 h, sustained migraine pain freedom from 2–24 h and from 2–48 h, and most bothersome symptom freedom at 2 h. Safety was assessed via adverse events (AEs) and laboratory tests. Results Overall, 585 participants (89.1% were female, mean age was 42.9 years) received study…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 585 participants or records.
