Real-world Evidence of Adding Atogepant to OnabotulinumtoxinA for Control of Chronic Migraine: A Retrospective Chart Review
Headache
P4 - Poster Session 4 (11:45 AM-12:45 PM)
12-001
Combination use of atogepant and onabotulinumtoxinA has the potential to be more effective than either alone for the preventive treatment of CM.
To collect real-world data to evaluate the effectiveness, safety, and tolerability of adding atogepant to onabotulinumtoxinA as combination preventive treatment for chronic migraine (CM).
This retrospective, longitudinal, multi-center chart review included adults with CM receiving ≥2 consecutive onabotulinumtoxinA cycles before ≥3mo of onabotulinumtoxinA and atogepant combination treatment. Charts at first atogepant prescription (index date) and 2 onabotulinumtoxinA injection visits (~3 and 6mo post-index) were reviewed for change from baseline in monthly headache days (MHDs), ≥50% reduction in MHDs, and rates and types of adverse events (AEs). Charts with CGRP agents for migraine prevention during baseline (~3mo pre-index) were excluded.

31 charts met eligibility criteria (mean age 46.7 years, 94% female). Atogepant 60 mg and 30 mg were administered QD to 30 and 1 patients, respectively. Throughout the study, patients received a mean dose of 170U onabotulinumtoxinA. Pre-onabotulinumtoxinA, the mean MHD was 24.0d, reduced by a mean -8.15d (95%CI -11.44,-4.85; n=25) after onabotulinumtoxinA pre-index (mean 3.97yr). MHD additionally decreased by mean -4.53d [95%CI -7.44,-1.61] after ~3mo of combination treatment (n=31) and -8.75d total [95%CI -13.21, -4.29] after ~6mo of combination treatment in patients with data available (n=23). Nearly half of patients (n=14/31) achieved ≥50% reduction in MHDs ~3mo post-index. Overall, 95% CIs indicate that reductions from baseline were statistically significant. No new safety signals were identified when atogepant was added to onabotulinumtoxinA. The most commonly reported AEs (≥5%) were constipation and fatigue.

This real-world pilot study of patients with CM demonstrated clinically meaningful treatment benefit in the reduction of headache days with onabotulinumtoxinA alone and additive benefits with co-administration of atogepant. Safety results were consistent with the known safety profiles of onabotulinumtoxinA and atogepant.
