AbbVie Submits Marketing Authorization Application to EMA for Atogepant for the Preventive Treatment of Migraine

  • The submission is based on two pivotal Phase 3 studies evaluating atogepant in adult patients with episodic and chronic migraine
  • If approved, atogepant would be the first daily oral calcitonin gene-related peptide (CGRP) receptor antagonist (gepant) for the prophylaxis of migraine in Europe
  • AbbVie would become the only company with a portfolio of medicines to offer two treatments for those with chronic migraine, one oral and one injectable

AbbVie (NYSE: ABBV) today announced it has submitted a marketing authorization application (MAA) to the European Medicines Agency (EMA) for atogepant for the prophylaxis of migraine in adult patients who have at least four migraine days per month. The application is supported by the pivotal Phase 3 ADVANCE and PROGRESS studies evaluating the safety, efficacy, and tolerability of atogepant in adult patients with episodic migraine and chronic migraine, respectively.1,2

Migraine is a complex neurological disease and one of the leading causes of disability worldwide.3 It is highly prevalent, affecting more than 1 billion people worldwide,3 including an estimated 11.4 percent of the population in Europe.4 If approved, atogepant would be the first daily oral CGRP receptor antagonist for the prophylaxis of migraine for adult patients in Europe.

“Far too many people around the world are impacted from the debilitating challenges of migraine, which places a significant social and work-life burden for patients and care partners,” said Michael Gold, M.D., therapeutic area head, neuroscience development, AbbVie. “At AbbVie, we are committed to advancing science to provide patients impacted by migraine with effective treatment options. If approved, atogepant will provide a prophylactic treatment option for adult migraine patients suffering for more than four days a month.”

The pivotal, Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group ADVANCE trial evaluated the efficacy, safety, and tolerability of once daily (QD) oral atogepant for the prophylaxis of episodic migraine. The study met its primary endpoint of a statistically significant reduction in mean monthly migraine days across the 12-week treatment period compared to placebo. This was found across all active treatment arms of atogepant – 10 mg, 30 mg, and 60 mg QD doses. The adult patients enrolled met the International Classification of Headache Disorders (ICHD) criteria for a diagnosis of migraine with or without aura. The study also found that a greater proportion of atogepant-treated participants achieved at least a 50% reduction in mean monthly migraine days for all doses compared to placebo and met other key secondary endpoints.

The pivotal, Phase 3, global, randomized, double-blind, placebo-controlled, parallel-group PROGRESS study, evaluating the safety, efficacy, and tolerability of oral atogepant in adult patients for the prophylaxis of chronic migraine, met its primary endpoint of statistically significant reduction from baseline in mean monthly migraine days compared to placebo across the 12-week treatment period. The trial also demonstrated that treatment with atogepant 60 mg once daily (QD) and 30 mg daily (BID), resulted in statistically significant improvements in all secondary endpoints. This includes a key secondary endpoint that measured the proportion of patients that achieved at least a 50 percent reduction in mean monthly migraine days across the 12-week treatment period.

In both, the Phase 3 PROGRESS and Phase 3 ADVANCE studies, all doses were well tolerated, and the overall safety profiles were consistent with safety findings observed in previous studies for the prophylaxis of episodic migraine and chronic migraine populations. The most common adverse events were constipation and nausea.

The atogepant MAA will be reviewed by the Committee for Medicinal Products for Human Use, which will issue an opinion that will be valid for all member states of the European Union, as well as Iceland, Lichtenstein, Northern Ireland and Norway.

About Atogepant
Atogepant is an orally administered, CGRP receptor antagonist (gepant) specifically developed for the prophylaxis treatment of migraine. CGRP and its receptors are expressed in regions of the nervous system associated with migraine pathophysiology. Studies have shown that CGRP levels are elevated during migraine attacks and selective CGRP receptor antagonists confer clinical benefit in migraine.

About the Phase 3 ADVANCE Clinical Trial1
The pivotal Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group trial was designed to evaluate the efficacy, safety, and tolerability of oral atogepant for the prevention of migraine in those with 4 to 14 migraine days per month. A total of 910 patients were randomized to one of four treatment groups evaluating 10 mg, 30 mg, or 60 mg of atogepant once daily, or placebo. Efficacy analyses were based on the modified intent-to-treat (mITT) population of 873 patients.

The primary endpoint was change from baseline in mean monthly migraine days across the 12-week treatment period. All atogepant dose groups met the primary endpoint and demonstrated statistically significantly greater decreases in mean monthly migraine days compared to placebo. Patients treated in the 10 mg/30 mg/60 mg atogepant arms experienced a decrease of 3.69/3.86/4.2 days, respectively, all compared to patients in the placebo arm, who experienced a decrease of 2.48 days (all dose groups vs. placebo, p=<.0001).

A key secondary endpoint measured the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across the 12-week treatment period. The trial demonstrated that 55.6%/58.7%/60.8% of patients in the 10 mg/30 mg/60 mg atogepant arms, respectively, achieved at least a 50% reduction, compared to 29.0% of patients in the placebo arm (all dose groups vs. placebo, p=<.0001).
