Eptinezumab-jjmr (Vyepti, Lundbeck) decreased mean monthly migraine days in adult patients in 2 phase 3 clinical trials.
Officials with the FDA have approved eptinezumab-jjmr (Vyepti, Lundbeck), the first intravenous (IV) treatment for the prevention of migraine in adults, according to a press release.
Eptinezumab-jjmr is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) ligand and blocks its binding to the receptor. The recommended dose is 100 mg every 3 months, but some patients may benefit from a 300-mg dose.
The approval is based on results from 2 phase 3 clinical trials: the PROMISE-1 in episodic migraine and PROMISE-2 in chronic migraine. In both studies, patients recieved either a placebo, eptinezumab-jjmr 100 mg, or eptinezumab-jjmr 300 mg. The primary endpoint was the change from baseline in mean monthly migraine day (MMD) over months 1 to 3. Patients were allowed to use concurrent acute migraine or headache medication, including migraine-specific medications, during the study.
Overall, the clinical trials demonstrated a treatment benefit over placebo for both doses of eptinezumab-jjmr as early as day 1 post-infusion. Additionally, the percentage of patients experiencing a migraine was lower for eptinezumab-jjmr than with placebo for most of the first 7 days. Among 2076 patients who received at least 1 dose of eptinezumab-jjmr, the most common adverse reactions were nasopharyngitis and hypersensitivity. In both trials, 1.9% of patients treated with eptinezumab-jjmr discontinued due to adverse reactions.
PROMISE-1 included a total of 665 patients who were randomized to 1 of the 3 treatment groups every 3 months for a 12-month period.
The results showed:
In PROMISE-2, a total of 1072 patents were randomized to receive a placebo, 100-mg eptinezumab-jjmr, or 300-mg eptinezumab-jjmr every 3 months for 6 months. According to the data:
“The PROMISE-2 data showed that many patients can achieve reduction in migraine days of at least 75% and experience a sustained migraine improvement through 6 months, which is clinically meaningful to both physicians and patients,” Dr Peter Goadsby, a professor of neurology at King’s College, London and the University of California, San Francisco, said in a statement. “Vyepti is a valuable addition for the treatment of migraine, which can help reduce the burden of this serious disease.”
Eptinezumab-jjmr will be available in April 2020, according to Lundbeck.
