Trajectory of migraine-related disability following long-term treatment with lasmiditan: results of the GLADIATOR study.


ABSTRACT: BACKGROUND:Migraine is recognized as the second leading cause of disability globally. Lasmiditan is a novel, selective serotonin 5-HT1F receptor agonist developed for acute treatment of migraine. Here we analyzed effects of lasmiditan on migraine disability assessed with the Migraine Disability Assessment (MIDAS) scale for interim data from a long-term safety study. METHODS:Completers of two single-attack parent studies were offered participation in the 1?year GLADIATOR study, that randomized participants to treatment with lasmiditan 100?mg or 200?mg taken as needed for migraine attacks of at least moderate severity. Changes in MIDAS were modeled using a mixed model repeated measures analysis. RESULTS:The sample included 1978 patients who received ?1 lasmiditan dose and were followed for a median of 288?days. Baseline mean MIDAS scores for the lasmiditan 100-mg and 200-mg groups were 29.4 and 28.9, respectively, indicating severe migraine-related disability. Relative to baseline, MIDAS total scores were significantly lower at 3, 6, 9, and 12?months for both dose groups. At 12?months, changes in MIDAS scores were?-?12.5 and?-?12.2 for lasmiditan 100?mg and 200?mg, respectively, with 49% and 53% of patients, respectively, achieving at least a 50% decrease in MIDAS total score. Statistically significant improvements were also seen for work and/or school absenteeism and presenteeism, monthly headache days, and mean headache pain intensity at all time points up to 1?year. Findings for patients who completed all visits versus those dropping out early were similar. Responses were generally similar for the lasmiditan 100?mg or 200?mg doses, between subgroups defined based on the number of baseline monthly migraine attacks (?5 vs. >5), and also between subgroups defined by pain-free response (yes/no) during initial attacks. CONCLUSIONS:Long-term treatment with lasmiditan was associated with significant reductions in migraine-related disability, including both work or school absenteeism and presenteeism. The similarity of responses in completers and those who dropped out suggests that selective attrition does not account for the improvements. Benefits were significant at 3?months and maintained through 12?months. TRIAL REGISTRATION:clinicaltrials.govNCT02565186; first posted October 1, 2015.
