NEW HAVEN, Conn., July 7, 2021 /PRNewswire/ --- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN; the "Company" or "Biohaven"), a biopharmaceutical company with a portfolio of innovative, late-stage product candidates, today announced preliminary net product revenue of NURTEC ODT (rimegepant) for the second quarter of 2021.

Based on preliminary unaudited financial information, the Company reported $93 million in net product revenue from sales of NURTEC ODT in the second quarter of 2021. Total prescriptions of NURTEC ODT from product launch to date (as of June 30, 2021) were over 750,000, with approximately 38,000 unique prescribers.

The foregoing information reflects the Company's estimate with respect to net product revenue for NURTEC ODT based on currently available information, which is preliminary and unaudited, is not a comprehensive statement of the Company's financial results and is subject to completion of the Company's financial closing procedures. The Company's final results will be issued upon completion of its closing procedures and may vary from these preliminary estimates.

Vlad Coric, M.D., Chief Executive Officer of Biohaven commented, "We are thrilled to report preliminary net product revenue of $93 million for NURTEC ODT in the second quarter that continues to exceed expectations and demonstrates the impact that NURTEC ODT is having on patients with migraine. During the quarter, we saw robust growth of NURTEC ODT in the acute treatment of migraine and initial strong growth in the preventive treatment of episodic migraine in the last few weeks after receiving the prevention approval from the FDA. As the first and only dual-therapy medication indicated to both treat and prevent migraines, NURTEC ODT is redefining the treatment paradigm for patients."

Approximately 40 million people in the U.S. and close to a billion individuals worldwide suffer from migraine. Migraine is the 3rd most prevalent illness in the world and the World Health Organization classifies migraine as one of the 10 most disabling medical illnesses.

BJ Jones, Chief Commercial Officer, added, "Our second quarter net revenue performance reflects the overwhelmingly positive feedback we are receiving from patients and healthcare providers about the impact of NURTEC ODT on migraine. Providing clinicians and patients with one oral medication that can be used to treat and prevent migraine is changing the impact of this disease for many of the millions of people who live with migraine and opens up an even larger market opportunity for the brand. Our teams are more energized than ever to continue to improve the lives of patients by delivering this first and only dual-therapy migraine medicine."

NURTEC ODT is the only migraine medication approved as a dual therapy for both the acute and preventive treatment, and is the first oral CGRP antagonist approved for the preventive treatment of migraine. NURTEC ODT targets the root cause of migraine by reversibly blocking CGRP receptors, thereby inhibiting the biologic cascade that results in a migraine attack. A single dose of NURTEC ODT can deliver fast pain relief with some patients returning to normal function by 60 minutes and has a lasting effect of up to 48 hours for many patients. NURTEC ODT can be taken up to once daily, up to 18 doses/month, as needed to stop migraine attacks or taken every other day to help prevent migraine attacks and reduce the number of monthly migraine days.

NURTEC ODT was approved by the U.S. Food and Drug Administration (FDA) for the acute treatment of migraine in February 2020 and for the preventive treatment of episodic migraine in May 2021 with the commercial launch commencing within weeks of the approvals.
