Effect of Atogepant for Preventive Migraine Treatment on Patient-Reported Outcomes in the Randomized, Double-blind, Phase 3 ADVANCE Trial.

Background And Objectives: The oral calcitonin gene-related peptide receptor antagonist atogepant is indicated for the preventive treatment of episodic migraine. We evaluated changes in patient-reported outcomes with atogepant in adults with migraine.

Methods: In this phase 3, 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group trial (ADVANCE), adults with 4-14 migraine days per month received atogepant (10, 30, or 60 mg) once daily or placebo. Secondary endpoints included changes from baseline in Migraine-Specific Quality-of-Life Questionnaire (MSQ) version 2.1 Role Function-Restrictive (RFR) domain at week 12 and mean monthly Activity Impairment in Migraine-Diary (AIM-D) Performance of Daily Activities (PDA) and Physical Impairment (PI) domains across the 12-week treatment period. Exploratory endpoints included change in MSQ Role Function-Preventive (RFP) and Emotional Function (EF) domains; AIM-D total scores; and change in Headache Impact Test (HIT)-6 scores.

Results: Of 910 participants randomized, 873 comprised the modified intent-to-treat population (atogepant: 10 mg [n = 214]; 30 mg [n = 223]; and 60 mg [n = 222]; placebo [n = 214]). All atogepant groups demonstrated significantly greater improvements vs placebo in MSQ RFR that exceeded minimum clinically meaningful between-group difference (3.2 points) at week 12 (least-square mean difference [LSMD] vs placebo: 10 mg [9.9]; 30 mg [10.1]; 60 mg [10.8]; all < 0.0001). LSMDs in monthly AIM-D PDA and PI scores across the 12-week treatment period improved significantly for the atogepant 30 (PDA: -2.54; = 0.0003; PI: -1.99; and = 0.0011) and 60 mg groups (PDA: -3.32; < 0.0001; PI: -2.46; < 0.0001), but not for the 10 mg group (PDA: -1.19; = 0.086; PI: -1.08; = 0.074). In exploratory analyses, atogepant 30 and 60 mg were associated with nominal improvements in MSQ RFP and EF domains, other AIM-D outcomes, and HIT-6 scores at the earliest time point (week 4) and throughout the 12-week treatment period. Results varied for atogepant 10 mg.

Discussion: Atogepant 30 and 60 mg produced significant improvements in key patient-reported outcomes including MSQ-RFR scores and both AIM-D domains. Nominal improvements also occurred for other MSQ domains and HIT-6, reinforcing the beneficial effects of atogepant as a new treatment for migraine prevention.
