Rimegepant for the acute treatment of migraine: A phase 3, multicenter, open-label, long-term safety and effectiveness study in adults from China
Abstract
BackgroundThis study evaluated the long-term safety, tolerability and effectiveness of rimegepant, 75 mg orally disintegrating tablet, for the acute treatment of migraine in Chinese adults.MethodsThis phase 3, multicenter, open-label, single-arm study enrolled Chinese adults with a ≥1 year history of migraine (with or without aura), 6-18 moderate-to-severe migraine attacks/month within three months before a screening visit and at least six migraine days during a 30-day observation phase (OP). After the OP, eligible participants took rimegepant as needed (maximum one tablet per day) at the onset of mild-to-severe migraine attack for a long-term treatment (LTT) of 52 weeks.ResultsOverall, 240 participants were treated and 208 (86.3%) completed the study. During LTT, 203 (84.6%) participants reported ≥1 treatment-emergent adverse event (TEAE) and 46 (19.2%) reported ≥1 TEAE considered to be rimegepant-related. There were no rimegepant-related serious AEs or rimegepant-related TEAEs that led to treatment interruption or discontinuation. Mean reduction from the OP in monthly migraine days was observed as early as the first four weeks (-1.7; 95% confidence interval = -2.2 to -1.2), with an overall mean reduction of -4.4 (95% confidence interval = -4.9 to -3.9) days across LTT.ConclusionsRimegepant had a favorable long-term safety profile, was well tolerated in Chinese participants, and a reduction in the number of monthly migraine days was observed during the LLT.Trial…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 240 participants or records.
