Biohaven will be presenting new and encore data presentations for Nurtec ODT (rimegepant), the first and only calcitonin gene-related peptide (CGRP) receptor antagonist in an orally disintegrating tablet (ODT) approved by the FDA for the acute and preventive treatment of migraine in adults. Nurtec ODT received FDA approval for the preventive treatment of episodic migraine in adults on May 27. Efficacy and safety results from the pivotal Phase 2/3 clinical trial of rimegepant for the preventive treatment for migraine will be presented including data showing a rapid reduction in migraine days. Additionally, posters feature data from the Phase 3 trials and the long-term safety study of rimegepant as an acute treatment for migraine, including in people who have a history of treatment failure with triptans. Health economics and outcomes research analyses shed light on the impact of redosing on cost utility outcomes and demonstrate that the use of rimegepant taken as an acute treatment on an as needed basis over one year was associated with a reduction in monthly migraine days and tablet utilization as well as improved quality of life outcomes. An oral presentation for the Phase 2/3 dose-ranging study of intranasal zavegepant, the only intranasal CGRP receptor antagonist currently in late-stage clinical trials for the acute treatment of migraine, will also be presented.

Elyse Stock, MD, Chief Medical Officer of Biohaven commented, "We continue to build on our deep body of research that demonstrates Nurtec ODT's clinical efficacy and safety for the acute and preventive treatment of migraine. We are energized by the recent FDA approval for Nurtec ODT as a preventive treatment for episodic migraine and are excited to bring forward this oral dual therapy indication to physicians and patients alike. The clinical and health economics data presented at AHS emphasize this paradigm changing treatment approach as the first and only medication that can treat and prevent migraine attacks."

Notable highlights include:

  • Data from a Phase 2/3 pivotal randomized, placebo-controlled trial assessing rimegepant for the preventive treatment of migraine demonstrated rapid preventive efficacy within the first week of every-other-day dosing, with sustained benefits observed across 12 weeks of double-blind treatment. Rimegepant was superior to placebo on the primary endpoint of change from the observation period in mean monthly migraine days (MMDs) during weeks 9-12 (−4.3 vs −3.5, p=0.0099) as well as on the secondary endpoint of ≥50% reduction in mean number of moderate or severe MMDs during weeks 9-12 (49% vs 41%, p=0.0438).
  • Subgroup analyses of triptan failure from the rimegepant clinical trials in the acute treatment of migraine demonstrated treatment with rimegepant up to once daily over one year improved migraine-related disability in subjects who had previously failed 1 or ≥2 triptans and in those who had no history of triptan treatment failure. Additionally, the data shows that rimegepant is effective, well-tolerated, and improves quality of life in those with a history of triptan treatment failure regardless of the number of triptans subjects had previously tried and failed.
  • Post-hoc 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 monthly migraine days (MMDs). Repeated acute treatment of migraine with rimegepant on an as needed basis achieved clinically relevant reductions in time to 30% and 50% MMDs decrease at 8 weeks and 20 weeks respectively. These findings are consistent with preventive benefits of rimegepant demonstrated in the pivotal Phase 2/3 clinical trial of rimegepant in the preventive treatment of migraine.
  • Post-hoc health economics and outcomes research showed that ongoing acute treatment of migraine with rimegepant on an as needed basis over one year of follow-up was found to be associated with reduced monthly migraine days, a corresponding reduction in monthly tablet utilization and did not lend to a trend indicative of medication overuse headache. Additional research also showed that when the impact of re-dosing is considered, rimegepant was associated with more favorable cost-effectiveness results versus usual care compared to ubrogepant and lasmiditan given that in the pivotal trials for these medications redosing was permitted, however this added cost was not incorporated in the recent ICER economic evaluation.
  • Data from a Phase 2/3 dose-ranging study of intranasal zavegepant for the acute treatment of migraine show that zavegepant 10 mg and 20 mg demonstrated statistical superiority to placebo on the co-primary 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 (MBS) freedom [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 2 hours post-dose. Rapid onset of pain relief was also observed as early as 15 minutes.

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 www.nurtec.com. 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.

Indication
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.

Important Safety Information
Do not take NURTEC ODT if you are allergic to NURTEC ODT (rimegepant) or any of its ingredients.

Before you take NURTEC ODT, tell your healthcare provider (HCP) about all your medical conditions, including if you:

  • have liver problems,
  • have kidney problems,
  • are pregnant or plan to become pregnant,
  • breastfeeding or plan to breastfeed.

Tell your HCP about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

NURTEC ODT may cause serious side effects including allergic reactions, including trouble breathing and rash. This can happen days after you take NURTEC ODT. Call your HCP or get emergency help right away if you have swelling of the face, mouth, tongue, or throat or trouble breathing. This occurred in less than 1% of patients treated with NURTEC ODT.

The most common side effects of NURTEC ODT were nausea (2.7%) and stomach pain/indigestion (2.4%). These are not the only possible side effects of NURTEC ODT. Tell your HCP if you have any side effects.

You are encouraged to report side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1–800–FDA–1088 or report side effects to Biohaven at 1–833–4NURTEC.

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.
