Eptinezumab is a humanized anti?calcitonin gene-related peptide monoclonal antibody with rapid onset of preventive benefit, FDA-approved for the preventive treatment of migraine in adults.
To evaluate the efficacy and safety of the preventive migraine treatment, eptinezumab, initiated during a migraine attack.
RELIEF (NCT04152083) was a parallel-group, double-blind, placebo-controlled study. Patients aged 18–75 years, with migraine on 4–15 days/month in 3 months prior to screening, were randomized to eptinezumab 100mg or placebo, administered IV within 1-6h of a moderate to severe migraine attack onset. Co-primary efficacy endpoints were time to headache pain freedom and time to absence of most bothersome symptom (MBS; nausea, photophobia, or phonophobia). Key secondary efficacy endpoints were headache pain freedom and absence of MBS at 2h; other secondary included headache pain freedom and absence of MBS at 4h and use of rescue medication within 24h. Safety and tolerability of eptinezumab administered during a migraine attack were also assessed.
Eptinezumab-treated patients (n=238) compared with placebo-treated patients (n=242) achieved significantly faster headache pain freedom (median 4h vs 9h, respectively; hazard ratio=1.54, P=0.0006) and absence of MBS (median 2h vs 3h, respectively; hazard ratio=1.75, P<0.0001). At 2h, in the respective eptinezumab and placebo groups, headache pain freedom was reported by 23.5% and 12.0% (P=0.0009), and absence of MBS by 55.5% and 35.5% (P<0.0001); results remained significant at 4h. Significantly fewer eptinezumab-treated patients used rescue medication within 24h vs placebo patients (31.5% vs 59.9%, respectively; P<0.0001). Treatment-emergent adverse events occurred in 10.9% eptinezumab-treated and 10.3% placebo patients; no serious adverse events occurred.
Initiating preventive therapy with eptinezumab during a migraine attack resulted in rapid and sustained freedom from headache pain and MBS compared with placebo, starting 2h post-infusion, and decreased need for acute medication within 24h post-infusion. No notable safety findings were identified.
