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 11 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. TRIAL REGISTRATION DETAILS ClinicalTrials.gov identifier NCT03096834.
