NORTH CHICAGO, Ill., April 12, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced an interim analysis of an ongoing Phase 3, open-label 156-week extension study evaluating the long-term safety and tolerability of oral atogepant for the prevention of migraine in participants with chronic or episodic migraine. The overall long-term safety results were consistent with the known safety profile of atogepant in chronic and episodic migraine, and no new safety signals were identified. These results also support improvements in key efficacy outcomes, including reduction in monthly acute medication use days.

"Migraine is a debilitating neurological disease that can have a significant impact on day-to-day life," said Sait Ashina, MD, assistant professor of neurology and anesthesia at Harvard Medical School, director of the Comprehensive Headache Center at Beth Israel Deaconess Medical Center in Boston, and lead author of the study. "As the first report of one-year atogepant data in patients with chronic migraine, this builds on the long-term observed safety and efficacy in the episodic migraine population and demonstrates atogepant's ability to reduce migraine days and acute medication use across the spectrum of the disease."

The extension study included participants who had enrolled in the Phase 3 PROGRESS and ELEVATE clinical trials with a baseline monthly migraine day burden of 14.5 days and completed these studies. Key findings from the interim analysis include:

• Monthly migraine days improved on average by 8.5 days at Weeks 13-16 and this was consistent over 48 weeks. Similar improvements were observed for monthly headache days and monthly acute medication use days.
• Seventy percent of subjects achieved ≥50% reduction in monthly migraine days at Weeks 13-16 and this was consistent during the 48 weeks of open-label treatment.
• Overall safety results were consistent with the known safety profile of atogepant 60 mg, and no new safety signals were identified.
• The most common treatment-emergent adverse events (≥5%) were COVID-19 (28.7%), nasopharyngitis (10.9%), and constipation (8.2%).

"We understand that migraine is a complex disease and AbbVie is steadfast in our commitment to alleviating the considerable burden facing migraine patients," said Dawn Carlson, vice president, neuroscience development, AbbVie. "Patients should accept nothing less than migraine freedom, and the long-term safety and efficacy shown in this interim analysis marks another step toward that goal."  

Atogepant, also known as QULIPTA^® in the U.S. and AQUIPTA^® in the European Union (EU), is approved in 45 countries. It is an oral calcitonin gene-related peptide (CGRP) receptor antagonist proven to prevent both episodic and chronic migraine in adults.

AbbVie will continue to pursue additional regulatory submissions for atogepant across international markets.

About Study 3101-312-002
Study 3101-312-002 is an ongoing Phase 3, multicenter, open-label 156-week extension study evaluating the long-term safety and tolerability of oral atogepant for the prevention of migraine in participants with chronic or episodic migraine. The primary objective was to evaluate safety and tolerability in all participants who received ≥1 dose of study intervention in the extension study (N = 595). Efficacy was evaluated by eDiary at Weeks 13-16, 29-32 and 45-48. The modified intention-to-treat population included participants who received ≥1 dose of atogepant and had ≥1 evaluable post-baseline 4-week period of eDiary data (N=524). Pre-specified efficacy endpoints included in the late-breaking data included change from baseline in monthly migraine days, monthly headache days, monthly acute medication use days and the proportion of participants with ≥ 50% improvement in monthly migraine days. The current interim analysis was performed after all study participants completed the efficacy data collection portion of the study at Week 52 or early termination. More information can be found on www.clinicaltrials.gov (NCT04686136).

About the ELEVATE Study
The ELEVATE study was a global, randomized, double-blind, placebo-controlled trial assessing the safety, tolerability, and efficacy of atogepant 60 mg once daily (QD) compared with placebo for the preventive treatment of episodic migraine in adult participants who have been failed by two to four classes of oral preventive treatments. The primary endpoint was the change from baseline in mean monthly migraine days (MMDs) across 12 weeks. Secondary endpoints included achievement of more than 50% reduction in MMDs, change from baseline in mean monthly headache days (MHDs), and change from baseline in acute medication use days across 12 weeks. More information can be found on www.clinicaltrials.gov (NCT04740827).

About the PROGRESS Study
The PROGRESS study was a global, randomized, double-blind, placebo-controlled Phase 3 trial assessing the efficacy, safety, and tolerability of atogepant for the preventive treatment of chronic migraine. Adults with a 1-year or longer history of chronic migraine were randomly assigned (1:1:1) to receive oral atogepant 30 mg twice a day (not a U.S. FDA-approved dose), oral atogepant 60 mg once a day, or placebo. The primary endpoint was change from baseline in mean monthly migraine days (MMDs) across the 12-week treatment period. Key secondary endpoints for all regions included proportion of participants with at least a 50% reduction in MMDs across the 12-week treatment period, change from baseline in mean monthly headache days (MHDs) across the 12-week treatment period, and change from baseline in mean monthly acute medication use days across the 12-week treatment period. More information can be found on www.clinicaltrials.gov (NCT03855137).

About Atogepant (QULIPTA^®)
Atogepant is an orally administered, CGRP receptor antagonist specifically developed for the preventive treatment of migraine in adults. 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.

Atogepant, known as AQUIPTA^® in the European Union, was approved by the European Commission in August 2023 for the prevention of episodic or chronic migraine in adults with 4 or more monthly migraine days (MMDs).

About Migraine and Chronic Migraine
Migraine is a complex neurological disease with recurrent attacks that are often incapacitating and characterized by severe, throbbing headache pain as well as compounding associated symptoms like extreme sensitivity to light, sound or nausea.¹ It is highly prevalent, affecting more than 1 billion people worldwide, including nearly 40 million people in the United States alone, and is the highest cause of disability worldwide for people under 50 years of age.^2-5

People living with chronic migraine experience headaches or migraine for 15 or more days per month, with at least eight of those days associated with migraine.⁶ It is differentiated from episodic migraine, which is characterized by 0-14 headache days per month,⁷ by its more debilitating disease profile including greater prevalence of comorbid conditions as well as higher frequency of headache and migraine days.^7-9 Individuals with chronic migraine experience frequent disabling migraine attacks, preventing them from performing daily activities and significantly affecting their quality of life. This results in substantial societal and familial burden.^10-14 Significant direct and indirect costs are also associated with chronic migraine, leading to economic burden for patients and healthcare systems.^15-17
