Safety and efficacy of ubrogepant in participants with major cardiovascular risk factors in two single-attack phase 3 randomized trials: ACHIEVE I and II

Abstract

Objective To examine the safety and efficacy of ubrogepant for acute treatment of migraine across cardiovascular (CV) disease risk categories. Methods ACHIEVE I and II were multicenter, double-blind, single-attack, phase 3 trials in adults with migraine, with or without aura. Participants were randomized 1:1:1 to placebo or ubrogepant (50 or 100 mg in ACHIEVE I; 25 or 50 mg in ACHIEVE II), to treat one migraine attack of moderate or severe headache pain intensity. This post-hoc analysis pooled data from ubrogepant 50 mg and placebo groups from the ACHIEVE trials to examine the safety and efficacy of ubrogepant by baseline cardiovascular disease risk factors. Using a cardiovascular risk assessment algorithm, participants were categorized as having no cardiovascular risk, low cardiovascular risk or moderate-high cardiovascular risk at baseline. Treatment-emergent adverse events were documented 48 h and 30 days after taking the trial medication. Co-primary efficacy outcomes were 2-h pain freedom and 2-h absence of most bothersome migraine-associated symptom. Results Overall, 3358 participants were randomized in the ACHIEVE trials (n = 2901 safety population; n = 2682 modified intent-to-treat population). In the safety population, 11% of participants were categorized as moderate-high (n = 311), 32% low (n = 920), and 58% no cardiovascular risk factors (n = 1670). The proportion of ubrogepant participants reporting a treatment-emergent adverse event was comparable across risk categories and similar to placebo. The treatment effects of ubrogepant versus placebo were consistent across cardiovascular risk categories for all efficacy outcomes. Conclusion The safety and efficacy of ubrogepant for the acute treatment of a single migraine attack did not differ by the presence of major cardiovascular risk factors. No evidence of increased treatment-emergent adverse events or cardiac system organ class adverse events with ≥2 major cardiovascular risk factors and no safety concerns were identified.
