AB Objective: To assess the effect of fremanezumab versus placebo on medication overuse and acute headache medication use in patients with chronic migraine (CM).Background: Overuse of acute or symptomatic headache medications, such as triptans, ergot derivatives, opioids, and combination analgesics, can cause medication overuse headache (MOH). CM is often accompanied by MOH. Fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), is efficacious in preventing CM.Design/Methods: In this Phase 3, multicenter, randomized, double-blind, placebo-controlled study, CM patients were randomized 1:1:1 to receive subcutaneous fremanezumab quarterly (675 mg at baseline, and placebo at Weeks 4 and 8), fremanezumab monthly (675 mg at baseline, and 225 mg at Weeks 4 and 8), or placebo (at baseline, Weeks 4 and 8). We assessed the proportion of patients who reverted from overusing medications at baseline to not overusing medications during the 12-week treatment period, and the change from baseline in the number of days of acute headache medication use.Results: Among patients with medication overuse at baseline (quarterly n=201; monthly n=198; placebo n=188), more patients treated with fremanezumab reported no medication overuse during the treatment period (quarterly: 55%, P=0.0389; monthly: 61%, P=0.0024) than those who received placebo (46%). Response to treatment was seen by Week 4 (quarterly: 51%, P=0.0091; monthly: 54%, P=0.0014; vs placebo: 39%). Among the patients who responded to treatment, the baseline number of days with medication overuse was similar across treatment groups (quarterly [mean]: 16.6 days; monthly: 16.7 days; placebo: 16.6). Within this population, fremanezumab treatment significantly reduced the days of acute headache medication use (quarterly: −9.0 days, P=0.0017; monthly: −8.9 days, P=0.0040) compared with those who received placebo (−7.1 days).Conclusions: Fremanezumab treatment was associated with a reduction in overuse of acute medications and a corresponding decrease in days using acute medications.Disclosure: Dr. Silberstein has received personal compensation for consulting, serving on a scientific advisory board, speaking, or other activities with Alder Biopharmaceuticals, Allergan, Amgen, Avanir, eNeura, ElectroCore Medical, Labrys Biologics, Medscape, Medtronic, Neuralieve, NINDS, Pfizer, and Teva.
