Atogepant is a potent, selective, oral calcitonin gene-related peptide (CGRP) receptor antagonist in development for migraine prevention. The chemical structure of atogepant is distinct from previous CGRP receptor antagonists, which were associated with elevated serum alanine aminotransferase (ALT) in clinical trials. Here, we report the safety, tolerability, and pharmacokinetics (PKs) of a once-daily supratherapeutic dose (170 mg) of atogepant for 28 days from a randomized, double-blind, placebo-controlled phase I trial in healthy participants. Overall safety, hepatic safety, and plasma PK parameters were evaluated. Thirty-four participants aged 23-55 years enrolled; 28 (82.4%) completed the study in accordance with the protocol. Multiple doses of 170 mg atogepant for 28 consecutive days were generally well-tolerated. All adverse events (AEs; reported in 87.0% of the atogepant group; 72.7%, placebo) were mild in severity except one serious AE of subarachnoid hemorrhage due to a bicycle accident and not considered related to treatment. There were two discontinuations due to AEs, both with atogepant, one considered possibly related to treatment. Over 28 days of treatment, no participant receiving atogepant had an ALT elevation above 1.5 × upper limit of normal. Change from baseline in serum ALT levels was not different between atogepant and placebo. Atogepant is rapidly absorbed (median time to maximum plasma concentration, ~ 2 hours) with an apparent terminal half-life of ~ 11 hours, and no evidence of accumulation after once-daily dosing. Overall, atogepant at a high oral dose is safe and well-tolerated in healthy participants with no clinically meaningful elevations in ALT.
Background And Objectives: Three phase 3 trials demonstrated the efficacy and safety of atogepant in episodic migraine (EM) and chronic migraine (CM) across 12-week treatment periods. This analysis evaluates improvements in efficacy and functional outcomes in the first 4 weeks of treatment with the oral calcitonin gene-related peptide receptor antagonist, atogepant, for the preventive treatment of migraine.
Methods: ADVANCE, ELEVATE, and PROGRESS were phase 3, multicenter, randomized, double-blind, placebo-controlled 12-week trials.
Background: Migraine is associated with obesity. These analyses evaluated weight change with atogepant used as a preventive migraine treatment.
Methods: Five atogepant clinical trials in adults with migraine (one phase 2b/3; four phase 3) were included: Three 12-week, randomized, placebo-controlled trials (episodic migraine: two; chronic migraine: one); one 40-week, open-label extension trial and one 52-week, standard care, randomized, long-term safety trial in episodic migraine.
Background: We aimed to assess the effects of preventive migraine treatment with atogepant vs. placebo on patient-reported quality of life and functioning.
Methods: Analyses of patient-reported outcomes from three 12-week, randomized, placebo-controlled trials evaluating preventive migraine treatment with atogepant 60 mg once-daily: ADVANCE (low-frequency episodic migraine [LFEM], 4-8 monthly migraine days [MMDs] and high-frequency episodic migraine [HFEM], 8-14 MMDs), PROGRESS (chronic migraine, CM) and ELEVATE (episodic migraine in those previously failed by two to four classes of oral preventive treatments).
Migraine is a common neurological condition marked by unilateral recurrent pulsating headaches, often associated with systemic signs and symptoms. Recently, calcitonin gene-related peptide (CGRP) antagonists, including atogepant, an oral CGRP receptor antagonist, have emerged as effective and safe treatments. The current study sought to assess the efficacy and safety of atogepant for preventing episodic migraines in adults.
