Background:
We present findings from the multicenter, double-blind Phase 3 study, CENTURION. This study was designed to assess the efficacy of and consistency of response to lasmiditan in the acute treatment of migraine across four attacks.
Methods:
Patients were randomized 1:1:1 to one of three treatment groups - lasmiditan 200 mg; lasmiditan 100 mg; or a control group that received placebo for three attacks and lasmiditan 50 mg for either the third or fourth attack. The primary endpoints were pain freedom at 2 h (first attack) and pain freedom at 2 h in ≥2/3 attacks. Secondary endpoints included pain relief, sustained pain freedom and disability freedom. Statistical testing used a logistic regression model and graphical methodology to control for multiplicity.
Results:
Overall, 1471 patients treated ≥1 migraine attack with the study drug. Both primary endpoints were met for lasmiditan 100 mg and 200 mg (p < 0.001). All gated secondary endpoints were met. The incidence of treatment-emergent adverse events (TEAEs) was highest during the first attack. The most common TEAEs with lasmiditan were dizziness, paresthesia, fatigue, and nausea; these were generally mild or moderate in severity.
Conclusions:
These results confirm the early and sustained efficacy of lasmiditan 100 mg and 200 mg and demonstrate consistency of response across multiple attacks.Trial Registration Number: NCT03670810.
