Calcitonin gene-related peptide (CGRP) receptor antagonist, orally-active small molecule
Numbers may be misleading, as many who experience migraine do not consult their GP, but migraine affects about 6% of men and 18% of women. In children it is more common in boys than in girls. The first attack is often in childhood and over 80% have had their first attack by the age of 30 [2].

Trial or other data

Dec 20PII/III RCT (NCT03732638; n=747) reports rimegepant was superior to placebo for change in mean number of migraine days per month during weeks 9–12 (−4.3 days vs. −3.5, respectively; mean difference −0.8, 95% CI −1.46 to −0.20; p=0.0099 [28].
Mar 20Biohaven Pharmaceuticals announces that a PII/III trial met its primary endpoint of reduction in mean number of migraine days in patients with migraine (NCT03732638; BHV3000-305). Those receiving rimegepant 75 mg every other day (n=348) experienced a statistically significant 4.5 day reduction from baseline in monthly migraine days, compared to a 3.7 day reduction in the placebo group (n=347; p=0.0176). Among study participants not taking concomitant preventive treatment, there was a 4.9 day reduction in monthly migraine days in the rimegepant group (n=273) compared with a 3.7 day reduction in the placebo group (n=269; nominal p=0.0020). A total of 22% of the study participants were taking a concurrent preventive treatment, including topiramate and amitriptyline. 48% of the rimegepant group had at least a 50% reduction from baseline in the mean number of moderate to severe migraine days per month compared to 41% in the placebo group [27].
Jul 19Results of PIII NCT03461757 are published; RCT (n=1466) reported that at 2 h postdose, rimegepant, an investigational calcitonin gene-related peptide receptor antagonist, was superior to placebo for freedom from pain (21% vs 11%, p<0.0001) and freedom from the most bothersome symptom (35% vs 27%, p=0.0009) [12].
Jul 19Results of NCT03237845 RCT (n=1186) are pulished; the study found rimegepant resulted in higher percentage of patients who were free of pain (19.6 vs. 12.0%; p<0.001) and free from most bothersome symptom (37.6 vs. 25.2% p<0.001) than placebo 2 hours after receiving dose. Most common adverse events were nausea and UTI [11].
Dec 18Pooled safety data released by Biohaven Pharmaceuticals for BHV-3000-301 (NCT03235479), BHV3000-302 (NCT03237845) and BHV3000-303 (NCT03461757) trials [9].
Oct 18Biohaven completes a PIII trial and evaluate the efficacy and safety of orally disintegrating tablet (ODT) formulation of rimegepant (the fast-dissolve Zydis®) in the treatment of acute migraine (BHV3000-303; NCT03461757). The randomised, double-Blind, placebo controlled trial was initiated in February 2018 and enrolled 1,466 patients in the US [9].
Mar 18Positive top-line results from two PIII trials (NCT03235479, NCT03237845) of rimegepant for migraine. In both trials, rimegepant met the co-primary efficacy endpoints of superiority to placebo at 2 hours after dosing in pain freedom and freedom from most bothersome symptoms such as nausea or sensitivity to light or sound. The rate of pain freedom in the 2 trials was 19.2% and 19.6% vs. 14.2% and 12% for placebo. Freedom from most bothersome symptoms was 37.6% and 36.6% v.s 25.2% and 27.7% in the placebo arm.[6]
Feb 18Biohaven initiates a third PIII efficacy study of rimegepant, for the treatment of migraine. The study is expected to complete in Q4 18 [9].
Nov 17Biohaven announces completion of enrollment in PIII study BHV3000-302 (NCT03237845). Together with PIII study BHV3000-301 (NCT03235479), the trials enrolled approximately 3,000 pts with migraine. Topline results are expected in Q1 of 2018. Long-term safety data will be evaluated in a third trial, Study BHV3000-201.[4,5]
Jul 17Two pivotal PIII randomised placebo-controlled trials initiated (NCT03235479, NCT03237845), both recruiting solely in the US. Both have the same design, with estimated recruitment of 850 patients each, and twin primary outcomes: freedom from pain at two hours, and freedom from the most bothersome symptom of nausea, phonophobia or photophobia, vs. placebo. Estimated completion for both trials is early February 2018 [3].
