Ubrogepant for the Treatment of Migraine
Abstract
BACKGROUND
Ubrogepant is an oral, small-molecule calcitonin gene-related peptide receptor antagonist for acute migraine treatment.
METHODS
We conducted a randomized trial to evaluate the efficacy, safety, and side-effect profile of ubrogepant. We assigned adults with migraine, with or without aura, in a 1:1:1 ratio to receive an initial dose of placebo, ubrogepant at a dose of 50 mg, or ubrogepant at a dose of 100 mg for treatment of a single migraine attack, with the option to take a second dose. The coprimary efficacy end points were freedom from pain at 2 hours after the initial dose and absence of the most bothersome migraine-associated symptom at 2 hours. Secondary end points included pain relief (at 2 hours), sustained pain relief (from 2 to 24 hours), sustained freedom from pain (from 2 to 24 hours), and absence of symptoms associated with migraine (photophobia, phonophobia, and nausea) at 2 hours.
RESULTS
A total of 1672 participants were enrolled; 559 were assigned to receive placebo, 556 to receive 50 mg of ubrogepant, and 557 to receive 100 mg of ubrogepant. The percentage of participants who had freedom from pain at 2 hours was 11.8% in the placebo group, 19.2% in the 50-mg ubrogepant group (P = 0.002, adjusted for multiplicity, for the comparison with placebo), and 21.2% in the 100-mg ubrogepant group (P<0.001). The percentage of participants who had freedom from the most bothersome symptom at 2 hours was 27.8% in the placebo group, 38.6% in the 50-mg ubrogepant…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 1,672 participants or records.
