Biohaven's NURTEC™ ODT (rimegepant) Receives FDA Approval for the Acute Treatment of Migraine in Adults

- First and only calcitonin gene-related peptide (CGRP) receptor antagonist available in a fast-acting orally disintegrating tablet (ODT)

- A single oral dose of NURTEC ODT 75 mg can provide fast pain relief and return patients to normal function within one hour, and deliver sustained efficacy that lasts up to 48 hours for many patients

- 86 percent of patients treated with a single dose of NURTEC ODT did not use a migraine rescue medication within 24 hours

NEW HAVEN, CT, USA I February 27, 2020 I Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN) today announced that the U.S. Food and Drug Administration (FDA) has approved NURTEC™ ODT (rimegepant) for the acute treatment of migraine in adults. NURTEC ODT is the first FDA-approved product for Biohaven, a company dedicated to advancing innovative therapies for neurological diseases.

A single quick-dissolving tablet of NURTEC ODT can provide fast pain relief and return patients to normal function within one hour, and deliver sustained efficacy that lasts up to 48 hours for many patients. NURTEC ODT disperses almost instantly in a person's mouth without the need for water, offering people with migraine a convenient, discreet way to take their medication anytime and anywhere they need it. NURTEC ODT is not indicated for the preventive treatment of migraine. Biohaven expects topline results from its prevention of migraine trial later this quarter.

Vlad Coric, M.D., CEO of Biohaven commented, "The FDA approval of NURTEC ODT marks an important milestone for the migraine community and a transformative event for Biohaven. Millions of people suffering from migraine are often not satisfied with their current acute treatment, at times having to make significant tradeoffs because of troublesome side effects and reduced ability to function. NURTEC ODT is an important new oral acute treatment for migraine that offers patients the potential to quickly reduce and eliminate pain and get back to their lives." Dr. Coric added, "We believe NURTEC ODT will be the first of many innovative Biohaven medicines to become available to treat devastating neurological diseases, a therapeutic category many other companies have abandoned. We are dedicated to helping patients with these conditions, who often have limited or no treatment options, live better, more productive lives."

NURTEC ODT, with its novel quick-dissolve oral tablet formulation, works by blocking CGRP receptors, treating a root cause of migraine. NURTEC ODT is not an opioid or narcotic, does not have addiction potential and is not scheduled as a controlled substance by the U.S. Drug Enforcement Administration.  

NURTEC ODT may offer an alternative treatment option, particularly for patients who experience inadequate efficacy, poor tolerability, or have a contraindication to currently available therapies. More than 3,100 patients have been treated with rimegepant with more than 113,000 doses administered in clinical trials, including a one-year long-term safety study. In the pivotal Phase 3 trial, NURTEC ODT was generally well tolerated; the most common adverse reaction was nausea (2%) in patients who received NURTEC ODT compared to 0.4% of patients who received placebo.

Mary Franklin, Executive Director of the National Headache Foundation commented, "Everyone knows someone living with migraine, yet it remains an invisible disease that is often overlooked and misunderstood. Almost all people with migraine need an acute treatment to stop a migraine attack as it occurs, which can happen without warning. The approval of NURTEC ODT is exciting for people with migraine as it provides a new treatment option to help people regain control of their attacks and their lives."

Peter Goadsby, M.D., Ph.D., Professor of Neurology and Director of the King's Clinical Research Facility, King's College Hospital commented, "I see many patients in my practice whose lives are disrupted by migraine, afraid to go about everyday life in case of a migraine attack. Many feel unsure if their acute treatment will work and if they can manage the side effects. With the FDA approval of NURTEC ODT, there is renewed hope for people living with migraine that they can get back to living their lives without fear of the next attack."

The FDA approval of NURTEC ODT is based on results from the pivotal Phase 3 clinical trial (Study 303) and the long-term, open-label safety study (Study 201). In the Phase 3 trial, NURTEC ODT achieved statistical significance on the regulatory co-primary endpoints of pain freedom and freedom from most bothersome symptom (MBS) at two hours post dose compared to placebo. NURTEC ODT also demonstrated statistical superiority at one hour for pain relief (reduction of moderate or severe pain to no pain or mild pain) and return to normal function. The benefits of pain freedom, pain relief, return to normal function and freedom from MBS were sustained up to 48 hours for many patients. Importantly, these benefits were seen with only a single dose of NURTEC ODT. Eighty-six percent of patients treated with NURTEC ODT did not require rescue medication (e.g. NSAIDS, acetaminophen) within 24 hours post dose. The long-term safety study assessed the safety and tolerability of rimegepant with multiple doses used over up to one year. The study evaluated 1,798 patients, who used rimegepant 75 mg as needed to treat migraine attacks, up to one dose per day. The study included 1,131 patients who were exposed to rimegepant for at least six months, and 863 who were exposed for at least one year, all of whom treated an average of at least two migraine attacks per month. The safety of treating more than 15 migraines in a 30-day period has not been established. 

NURTEC ODT is contraindicated in patients with a history of hypersensitivity to rimegepant, NURTEC ODT, or to any of its components. Hypersensitivity reactions with dyspnea and severe rash, including delayed serious hypersensitivity days after administration, occurred in less than 1% of subjects taking NURTEC ODT in clinical studies.

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 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. For more information about NURTEC ODT, visit www.nurtec.com.

About Migraine
Nearly 40 million people in the U.S. suffer from migraine and the World Health Organization classifies migraine as one of the 10 most disabling medical illnesses. Migraine is characterized by debilitating attacks lasting four to 72 hours with multiple symptoms, including pulsating headaches of moderate to severe pain intensity that can be associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia). There is a significant unmet need for new acute treatments as more than 90 percent of migraine sufferers are unable to work or function normally during an attack.

About CGRP Receptor Antagonism
Small molecule CGRP receptor antagonists represent a novel class of drugs for the treatment of migraine. This unique mode of action potentially offers an alternative to current agents, particularly for patients who have contraindications to the use of triptans, or who have a poor response to triptans or are intolerant to them.

What is NURTEC ODT? 
NURTEC™ ODT (rimegepant) is indicated for the acute treatment of migraine with or without aura in adults.

Limitations of Use
NURTEC ODT is not indicated for the preventive treatment of migraine.
