- Long-term acute treatment of migraine attacks with rimegepant 75 mg lowered monthly disease burden by reducing the number of monthly migraine days (MMDs)

- Clinically significant reduction in MMD frequency was observed over time regardless of baseline migraine frequency (baseline MMDs of 8.7 (low), 11.5 (med) and 14.8 (high))

- Rimegepant 75 mg repeated use shows no signal of medication overuse headache (MOH) which is a drug-induced increase in migraine days that occurs from other acute treatments

PR Newswire

NEW HAVEN, Conn., Feb. 3, 2022 /PRNewswire/ -- Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN) announced the publication of new findings from its long-term safety study showing reductions in migraine frequency in patients treated with rimegepant 75 mg for the acute treatment of migraine in the February issue of Cephalalgia Reports. Cephalalgia Reports is a medical-neurological journal in the field of headache research and is an official journal of the International Headache Society.

The published paper describes outcomes from patients treated with rimegepant 75 mg as needed (PRN) for the acute treatment of migraine, expressed as median time to ≥30% and ≥50% reduction in monthly migraine days (MMD). The 1044 patient study population was derived from the Open Label Safety Study BHV3000-201 (NCT03266588). This was a post-hoc analysis of adults with >6 MMD at baseline who self-administered rimegepant 75 mg orally PRN for acute treatment of migraine up to 52-weeks in an open-label safety study (BHV3000-201). This study is the first to utilize Kaplan–Meier and Cox Proportional Hazards methodology to describe longitudinal changes in migraine frequency.

Gil L'Italien Ph.D., Senior Vice President, GHEOR & Epidemiology, Biohaven, and lead author of the study, commented, "The Kaplan-Meier methodology provides for a novel assessment of migraine treatment efficacy and enables the ability to estimate adjusted hazard ratios for time to these outcomes (i.e., via Cox regression). These observations of migraine frequency reduction from repeated effective acute rimegepant treatment show reductions in migraine days after repeated acute therapy and are consistent with NURTEC ODT's known preventive effects."

Biohaven conducted the study in collaboration with health economic and outcomes research consultants led by Karissa Johnston, Ph.D., Scientific Director from Broadstreet HEOR, located in Vancouver, BC.

The published data shows that long-term acute treatment of migraine attacks with rimegepant 75 mg lowered monthly disease burden by reducing the number of migraine days, see Figure 1.

Clinically significant reduction in MMD frequency was observed over time regardless of baseline migraine frequency, including low-frequency (baseline MMD 8.7), moderate frequency (baseline MMD 11.5) and high-frequency (baseline MMD 14.8) cohorts. Adjusted (age and gender) hazard ratios for time to >30% and >50% in baseline MMD reductions were greatest for the lowest frequency cohort 5.47 (95% CI: 4.27, 7.00) for ≥30% MMD reduction and 5.74 (95% CI: 4.22, 7.81) for ≥50% MMD reduction, reflective of a faster median time to ≥30% and ≥50% MMD reduction for this cohort.

Dr. Johnston commented, "The study results confirm that continued use of rimegepant as an acute treatment to help stop a migraine can also lessen the number of migraine attacks a person has over time. This is a significant added benefit that healthcare providers and patients should consider when determining the right acute treatment plan."

NURTEC® ODT (rimegepant) 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.

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 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. Please click here for full NURTEC ODT Prescribing Information and Patient Information.

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 treatments as more than 90 percent of people with migraine are unable to work or function normally during an attack.

CGRP Receptor Antagonism
Small molecule CGRP receptor antagonists represent a novel class of drugs for the treatment of migraine. CGRP receptor antagonists work by reversibly blocking CGRP receptors, thereby inhibiting the biologic activity of the CGRP neuropeptide. For acute treatment, this unique mode of action potentially offers an alternative to other 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. CGRP signal-blocking therapies have not been associated with medication overuse headache (MOH) or rebound headaches which limits the clinical utility of other acute treatments due to increases in migraine attacks that result from frequent use.
