Teva Pharma’s Fremanezumab Receives FDA Acceptance for the Treatment of a Migraine

Teva Pharmaceutical Industries Ltd. has reported that the European Medicines Agency (EMA) has accepted the Marketing Authorization Application (MAA) for fremanezumab, an anti-calcitonin gene-related peptide (CGRP) antibody for the prevention of an episodic and chronic migraine in adults. Fremanezumab is a quarterly or monthly injection that might be administered by a fremanezumab professional, or self-administered by the patient.

Ernesto Aycardi, MD, vice president head of clinical trial execution, Data Sciences and Biometrics & Clinical Pharmacology at Teva said, “The successful filing of the MAA for fremanezumab with the EMA builds on the momentum of the global fremanezumab program, following the MAA acceptance of the Biologics License Application with the US Food and Drug Administration”.

“With limited availability of preventive Teva Pharma's Fremanezumab Receives FDA Acceptance for the Treatment of a Migraine treatment options that objective the underlying biological mechanisms of a migraine, the MAA acceptance represents a major step toward advancing the treatment paradigm for the migraine community.

These two significant regulatory milestones in the migraine indication, combined with our clinical development programs for fremanezumab in a cluster headache and post-traumatic headache, highlight Teva’s commitment regarding patients worldwide with these debilitating conditions.”

The MAA includes data from the HALO clinical trial program, which enrolled more than 2,000 patients with an episodic migraine (EM) and chronic migraine (CM), evaluating both quarterly and monthly dosing regimens, in which fremanezumab achieved statistically significant outcomes overall trial endpoints. In clinical trials, the most common adverse events reported injection site pain, induration, and erythema.

The phase III HALO EM and CM studies were 16-week, randomized, double-blind, multicenter, placebo-controlled, parallel-group studies to compare the safety, efficacy, and tolerability of four dose regimens of subcutaneous fremanezumab compared with placebo in adults with an episodic and chronic migraine.

The studies consisted of a screening visit, a 28-day run-in period, and a 12-week (84-day) treatment period, including a final evaluation at week 12 (end-of-treatment [EOT] visit, four weeks [28 days] after the final dose of study drug).

In the EM study, 875 patients were enrolled (294, 291, and 290 patients in the placebo, quarterly, and monthly dose groups, respectively). Patients were randomized in a 1:1:1 ratio to receive subcutaneous injections of fremanezumab at 225 mg for three months (monthly dose regimen), fremanezumab at 675 mg at initiation followed by placebo for two months (quarterly dose regimen), or three monthly doses of matching placebo.

The primary efficacy endpoint of the EM study was the mean change from baseline (28-day run-in period) in the monthly average number of migraine days during the 12-week period after the first dose of fremanezumab.

In the CM study, 1,130 patients were randomized (around 376 patients per treatment group). Patients were randomized in a 1:1:1 ratio to receive subcutaneous injections of fremanezumab at 675 mg at initiation followed by monthly 225 mg for two months (monthly dose regimen), fremanezumab at 675 mg at initiation followed by placebo for two months (quarterly dose regimen), or three monthly doses of matching placebo.

The primary efficacy endpoint of the CM study was the mean change from baseline (28-day run-in period) in the monthly average number of headache days of at least moderate severity during the 12-week period after the first dose of fremanezumab.
