Erenumab versus topiramate: migraine‐related disability, impact and health‐related quality of life.

Background and purpose: HER‐MES was the first head‐to‐head study of erenumab against topiramate (standard of care). This post hoc analysis of the HER‐MES study evaluated the effect of erenumab versus topiramate on patient‐reported outcomes at week 24. Methods: Adult patients with episodic or chronic migraine (n = 777) were randomized (1:1) to monthly subcutaneous erenumab (n = 389) or daily oral topiramate (n = 388). Migraine‐related disability, as measured by the Headache Impact Test 6 (HIT‐6) and Short Form 36 Health Survey version 2 (SF‐36v2), was analysed in the entire study cohort and true completers. Results: In the erenumab group (vs. topiramate), significant improvements were reported in Headache Impact Test 6 total scores (composite populations, −10.88 vs. −7.72; true completers, −11.92 vs. −10.61) and a higher proportion of patients achieved a ≥5‐point reduction from baseline with erenumab (composite populations, 72.2% vs. 53.9%; true completers, 79.64% vs. 71.43%). The adjusted mean change from baseline in the SF‐36v2 score was greater with erenumab for both physical component summary (composite population, 5.48 vs. 3.63; true completers, 5.95 vs. 5.23) and mental component summary (composite populations, 1.00 vs. −1.18; true completers, 1.74 vs. −0.33). A higher proportion of patients on erenumab versus topiramate had a ≥5‐point improvement in SF‐36v2 for the physical component summary (composite populations, 47.7% vs. 37.4%; true completers, 52.1% vs. 48.9%) and mental component summary (composite populations, 25.3% vs. 16.8%; true completers, 27.3% vs. 17.7%). Conclusions: This post hoc analysis demonstrated that patients treated with erenumab had significant improvements in headache impact and quality of life as measured by patient‐reported outcomes versus patients treated with topiramate.
