Biohaven will be presenting most recent data for its migraine portfolio including Nurtec® ODT (rimegepant) orally dissolving tablets 75 mg, the first and only calcitonin gene-related peptide (CGRP) receptor antagonist in an orally disintegrating tablet (ODT) approved by the FDA for the acute treatment of migraine and the preventive treatment of episodic migraine in adults; and intranasal zavegepant, the only intranasal CGRP receptor antagonist currently in late-stage clinical trials for the acute treatment of migraine.

The rimegepant studies include two late breaking abstracts and two oral presentations spotlighting the efficacy and safety data for rimegepant as an acute and preventive treatment of migraine. One poster showcases Phase 2/3 data for rimegepant and other highlights several health economics and outcomes research analyses including a late breaking oral lecture on time to monthly migraine days (MMDs) reduction.

Elyse Stock, MD, Chief Medical Officer of Biohaven commented, "Nurtec ODT has changed the treatment paradigm for migraine with an easy to use, oral CGRP antagonist that is now indicated for both the acute treatment and prevention of migraine. Our research efforts to help people with migraine are demonstrated by the breadth of posters presented at the 2021 International Headache Congress. Our focus remains strong on analyzing the burden of migraine and our health economics and outcomes research analysis spotlights important issues affecting those living with this debilitating disease."

Notable highlights include:

  • Data from a Phase 2/3 clinical trial to evaluate the safety and efficacy of rimegepant as a preventive treatment of migraine compared to placebo demonstrated that oral rimegepant taken every other day showed rapid migraine preventive effects as early as the first week of dosing. Additionally, it was observed to be superior to placebo across both primary and secondary endpoints of the trial. These include ≥50% reduction in the mean number of moderate or severe MMDs during weeks 9-12 (49% vs 41%, p=0.0438) and change in the mean number of total MMDs during Weeks 1-12 (−4.3 vs −3.5, p=0.0099).
  • Results from an open label safety study of rimegepant demonstrated its preventive benefits when dosed on an as needed basis to treat migraine attacks, expressed as median time to 30% and 50% reduction in MMDs observed to decrease at 12 weeks and 32 weeks respectively. Additionally, the long-term use of rimegepant 75 mg was associated with reductions in MMDs without evidence of medication-related increases in headache frequency. A different analysis that evaluated the safety of rimegepant in those with cardiovascular (CV) risk showed that rimegepant dosed up to once daily for up to 1 year showed favorable safety and tolerability in adults with migraine with CV risk factors, including adults with moderate to high CV risk.
  • A long-term open label safety study assessed patient preference, satisfaction, and improved clinical global impression of change (CGI-C) with rimegepant 75 mg for the acute treatment of migraine. Data showed that at week 24, 78.7% of subjects preferred rimegepant over their previous migraine medications, 89.4% of subjects were satisfied with rimegepant, and 88.8% of subjects were considered improved since study entry on the CGI-C scale. Among individuals using rimegepant as an acute treatment for one year, four in five preferred rimegepant to their previous migraine medications, seven in 10 were satisfied with rimegepant, and nine in 10 experienced clinical improvement relative to baseline.
  • A U.S.-based real world longitudinal analysis showed that migraine-related absenteeism was common, affecting more than two-thirds of the analyzed cohort and was associated with higher medical and pharmaceutical claims and healthcare costs. The analysis evaluated migraine-related absenteeism and its association with healthcare utilization and cost among adults with migraine.
  • A Phase 2/3 dose-ranging study evaluating the safety, efficacy and tolerability of intranasal zavegepant for the acute treatment of migraine demonstrated that zavegepant 10 mg and 20 mg were superior to placebo on the coprimary endpoints of pain freedom [placebo: 15.5%; 5 mg: 19.6% (p=0.1214); 10 mg: 22.5% (p=0.0113); 20 mg: 23.1% (p=0.0055)] and most bothersome symptom [placebo: 33.7%; 5 mg: 39.0% (p=0.1162); 10 mg: 41.9% (p=0.0155); 20 mg: 42.5% (p=0.0094)] at two hours post dose. The most common (>5%) adverse events (AEs) with zavegepant were altered taste (13.5%-16.1% vs 3.5% with placebo) and nasal discomfort (1.3%-5.2% vs 0.2% with placebo).

About Nurtec ODT
NURTEC ODT (rimegepant) is the first and only calcitonin gene-related peptide (CGRP) receptor antagonist available in a quick-dissolve ODT formulation that is approved by the U.S. Food and Drug Administration (FDA) for the acute treatment of migraine with or without aura and the preventive treatment of episodic migraine in adults. The activity of the neuropeptide CGRP is thought to play a causal role in migraine pathophysiology. NURTEC ODT is a CGRP receptor antagonist that works by reversibly blocking CGRP receptors, thereby inhibiting the biologic activity of the CGRP neuropeptide. The recommended dose of NURTEC ODT is 75 mg, taken as needed, up to once daily to treat or every other day to help prevent migraine attacks. For more information about NURTEC ODT, visit The most common adverse reaction was nausea and abdominal pain/indigestion. Avoid concomitant administration of NURTEC ODT with strong inhibitors of CYP3A4, strong or moderate inducers of CYP3A or inhibitors of P-gp or BCRP. Avoid another dose of NURTEC ODT within 48 hours when it is administered with moderate inhibitors of CYP3A4.

NURTEC ODT orally disintegrating tablets is a prescription medicine that is used to treat migraine in adults. It is for the acute treatment of migraine attacks with or without aura and the preventive treatment of episodic migraine. It is not known if NURTEC ODT is safe and effective in children.

About Zavegepant
Zavegepant is a third generation, high affinity, selective and structurally unique, small molecule CGRP receptor antagonist from Biohaven's NOJECTION™ Migraine Platform and the only CGRP receptor antagonist in clinical development with both intranasal and oral formulations. The efficacy and safety profile of intranasal zavegepant for the acute treatment of migraine, as compared to placebo, was shown in a randomized controlled Phase 2/3 dose-ranging trial with a total of over 1000 patients who received zavegepant. In this study, zavegepant showed statistical superiority to placebo on the coprimary endpoints of 2 hour freedom from pain and freedom from a patients' most bothersome symptom (either nausea, photophobia or phonophobia). Following successful end of Phase 2 interactions with FDA (clinical and nonclinical), zavegepant is advancing to Phase 3 for the acute treatment of migraine in adults. For more information, visit
