Objective To assess the efficacy of erenumab, a human anti-CGRP receptor antibody, in chronic migraine (CM) patients with and without allodynia.

Background Allodynia is associated with migraine chronification and may have negative implications for prognosis and treatment responsiveness. Erenumab is approved in the US and EU for migraine prevention; however, the impact of allodynia on erenumab efficacy is unknown.

Design/Methods Post-hoc analysis of a pivotal double-blind, randomized 3-month study of erenumab (70 mg or 140 mg monthly) in CM patients (NCT02066415) was performed for subgroups with the extremes of allodynia at baseline: no allodynia (Allodynia Symptom Checklist [ASC]12 sum score <3) vs moderate-severe allodynia (ASC-12 ≥6). Efficacy was measured as change from baseline in monthly migraine days (MMDs). Due to sample size considerations, results were pooled for the two erenumab dose groups

Results

Of 648 randomized patients with baseline ASC-12 allodynia scores, 386 (59.6%) had no allodynia and 153 (23.6%) had moderate-severe allodynia. Mean (SD) baseline MMDs were 17.6 (4.8) and 18.9 (4.3), respectively.

Compared to placebo, erenumab had greater MMD reductions at month 3 in both subgroups. Least-square mean (95% CI) changes were -6.6 (-7.4, -5.8) vs -4.0 (-4.9, -3.1) in the no allodynia subgroup and -7.3 (-8.6, -6.1) vs -4.1 (-5.7, -2.5) in the moderate-severe allodynia subgroup. Respective treatment differences were -2.5 (-3.7, -1.4) (p=0.001) and -3.3 (-5.3, -1.3) (p<0.001).

Proportions of patients achieving ≥50% MMD reductions at month 3 were greater for erenumab vs placebo in both allodynia subgroups. Response rates were 41.5% vs 23.2% (odds ratio [95% CI] erenumab vs placebo: 2.34 [1.49, 3.68]; p<0.001) for no allodynia and 44.0% vs 23.0% (OR: 2.69 [1.27, 5.70]; p=0.008) for moderate-severe allodynia.

Conclusions Erenumab demonstrated efficacy in CM patients both without allodynia and with moderate-severe allodynia. These results suggest that allodynia does not negatively predict treatment response to erenumab.
