Abstract

Objective To evaluate the effect of erenumab on patient-reported, functional outcomes in patients with episodic migraine (EM) in whom 2–4 preventives were not useful from the Phase 3b LIBERTY study.

Methods As previously reported, 246 patients with EM with 2–4 prior failed preventives were randomised 1:1 to subcutaneous erenumab 140 mg or placebo every 4 weeks for 12 weeks. This analysis evaluated Migraine Physical Function Impact Diary (MPFID), Headache Impact Test (HIT-6) and Work Productivity and Activity Impairment (WPAI) scores at Week 12. P values were nominal without multiplicity adjustment.

Results Erenumab significantly improved MPFID-Physical Impairment (PI) and Everyday Activities (EA) scores versus placebo (treatment difference (TD) (95% CI) MPFID-PI: −3.5 (−5.7 to –1.2) (p=0.003); MPFID-EA: −3.9 (−6.1 to –1.7)) (p<0.001) at 12 weeks. Patients on erenumab were more likely to have a ≥5-point reduction in MPFID score (OR vs placebo (95% CI) MPFID-EA: 2.1 (1.2 to 3.6); MPFID-PI: 2.5 (1.4 to 4.5)). A similar trend was observed for HIT-6 (TD: −3.0; p<0.001); significantly higher proportions of patients on erenumab reported a ≥5-point reduction (OR (95% CI): 2.4 (1.4 to 4.1)). In three out of four WPAI domains, erenumab showed improvement versus placebo.

Conclusion At 12 weeks, erenumab was efficacious on functional outcomes in patients with EM in whom 2–4 preventives were not useful.
