Biohaven Underscores Depth of Migraine Portfolio with Data from Nurtec® ODT (rimegepant) Long-Term Open Label Study and Phase 3 Zavegepant Trial at 64th Annual Scientific Meeting of the American Headache Society

• 31 new and encore presentations, including three late-breakers and three oral presentations, spotlight robust Nurtec ODT, zavegepant and migraine HEOR data
• Late-breaking submissions showcase new data for Nurtec ODT in Chinese and Korean patients and patterns of medication utilization in adults using it as an acute and preventive treatment
• Results from long-term studies of Nurtec ODT as a preventive and acute treatment of migraine showed more than 80% of patients achieved ≥50% reduction in moderate or severe monthly migraine days and approximately half experienced a 100% reduction
• Other oral presentations included safety and efficacy of zavegepant nasal spray as an acute treatment of migraine and an analysis of placebo responses over time in oral migraine preventive trials

NEW HAVEN, Conn., June 9, 2022 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN), today announced that it will be presenting 31 abstracts, including three late-breakers and three oral presentations, at the 64^th annual scientific meeting of the American Headache Society (AHS) being held from June 9-12 in Denver, CO.

Biohaven will be showcasing key efficacy and safety data for its calcitonin gene-related peptide (CGRP) platform including full Phase 3 results for zavegepant nasal spray as an acute treatment of migraine; data from a 52-week open label extension study of Nurtec® ODT (rimegepant) evaluating every other day preventive treatment of migraine plus as an as-needed acute treatment – a first of its kind study assessing acute and preventive treatment with one medication; and estimated reductions in monthly migraine days (MMDs) with rimegepant acute treatment. The late-breakers will highlight new data about patterns of medication utilization and migraine frequency for adults using Nurtec ODT as a preventive and acute treatment; results from a Phase 1 trial of Nurtec ODT in healthy Chinese adults; and outcomes of a Phase 3 study of Nurtec ODT conducted in China and Korea as an acute treatment of migraine. 

Additional posters will share information from a Delphi Panel of migraine experts that established consensus around flexible, individualized migraine treatment and the utility of situational preventive migraine treatment for times when patients have predictable yet unavoidable triggers and for expected situations when migraine prevention is particularly desired, such as important life events. Several health economics and outcomes research (HEOR) posters notably highlight (1) reductions in the prevalence of medication overuse headache following Nurtec ODT initiation, (2) reduced mean monthly quantity of dispensed Nurtec ODT which is potentially reflective of MMD reductions, (3) patient survey studies that illustrate preference for ODT oral formulations versus injectable or IV treatments in prevention, (4) improvements in health-related quality of life with long-term Nurtec ODT treatment, (5) the high interictal burden of migraine, and (6) patient reported attenuation of effect with biologic treatment in prevention.

Elyse Stock, MD, Chief Medical Officer of Biohaven commented, "The data presented at AHS 2022 highlights Biohaven's leadership in pioneering migraine-related research and a deep commitment to helping patients who live with this debilitating disease. We are working to expand our migraine portfolio to continue to have a positive impact on the lives of people with migraine and offer the ability to individualize care depending on patient treatment needs. Data from the first of its kind long-term, open-label study for Nurtec ODT showed that it is a safe and effective, all-in-one FDA-approved medication that helped almost half of the subjects achieve 100% reduction in monthly migraine days. Additionally, the FDA has recently accepted for review an NDA for zavegepant nasal spray as potentially another effective treatment option for migraine."

A complete list of abstracts is available below along with details about the late-breakers and oral presentations by our investigators. Abstracts will also be published in the June edition of Headache journal or shared as a supplement along with the main edition.

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. Avoid another dose of NURTEC ODT within 48 hours when it is administered with moderate inhibitors of CYP3A4 or potent inhibitors of P-gp.

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,
• are 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, 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). This was the second zavegepant pivotal clinical trial to meet these coprimary endpoints. The U.S. Food and Drug Administration has accepted a new drug application for zavegepant with a Prescription Drug User Fee Act date in the first quarter of 2023.
