Early response to eptinezumab indicates high likelihood of continued response in patients with chronic migraine.

ABSTRACT:

Background

A clinical ability to describe the response trajectory of patients receiving preventive migraine treatment could expedite and improve therapeutic management decisions. This post hoc analysis of the PROMISE-2 study evaluated the consistency and predictive power of Month 1 treatment response on later response in patients with chronic migraine.

Methods

PROMISE-2 was a double-blind, placebo-controlled trial that randomized adults with chronic migraine to eptinezumab 100 mg, 300 mg, or placebo administered IV every 12 weeks for up to 24 weeks (2 infusions over 6 study months). Migraine responder rates (MRRs) were calculated from monthly migraine days over 4-week intervals compared with baseline. Patients were grouped by MRR during Month 1 (< 25%, 25-< 50%, 50-< 75%, an
