Patient-reported migraine-specific quality of life, activity impairment and headache impact with once-daily atogepant for preventive treatment of migraine in a randomized, 52-week trial

Abstract

Background: Atogepant is an oral, small-molecule, calcitonin gene-related peptide receptor antagonist for the preventive treatment of episodic migraine.

Methods: In this 52-week, multicenter, randomized, open-label trial, adults with 4-14 monthly migraine days received atogepant 60 mg once-daily or standard care. Health outcome endpoints collected from participants randomized to atogepant included change from baseline in Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQ v2.1) Role Function-Restrictive (RFR), Role Function-Preventive (RFP) and Emotional Function (EF) domain scores, change in Activity Impairment in Migraine-Diary (AIM-D) Performance of Daily Activities (PDA) and Physical Impairment (PI) domain scores, and change in Headache Impact Test-6 (HIT-6) total score.

Results: Of 744 randomized participants, 521 received atogepant 60 mg in the modified intent-to-treat population. Least-squares mean changes from baseline in MSQ-RFR score were 30.02 (95% confidence interval = 28.16-31.87) at week 12 and 34.70 (95% confidence interval = 32.74-36.66) at week 52. Improvements were also observed in other MSQ domains, AIM-D PDA, PI and HIT-6 total scores. A ≥5-point improvement from baseline in HIT-6 score was observed in 59.9% of participants at week 4 and 80.8% of participants at week 52.

Conclusion: Over 52 weeks, atogepant 60 mg once-daily was associated with sustained improvements in quality of life and reductions in activity impairment and headache impact.Trial Registration: NCT03700320.
