An Open-label, Long-term, Safety Study of Lasmiditan for the Acute Treatment of Migraine

Phase 3

Completed

Brief Summary: This is a prospective, randomized, open-label study in subjects with migraine who have completed the Phase 3 studies, COL MIG 301/LAHJ (NCT02439320) or COL MIG-302/LAHK (NCT02605174) or for a subset of lasmiditan-naïve subjects with migraine. The study is designed to evaluate the safety and tolerability of long-term intermittent use of lasmiditan 100 mg and of lasmiditan 200 mg, as the first dose and as a second dose, for the acute treatment of migraine. Long term efficacy will also be evaluated.

Arm && Interventions

Group	Intervention	Description
Lasmiditan 100mg	Lasmiditan	Participants received oral dose of 100 milligrams (mg) Lasmiditan with in four hours of onset of migraine attack. If the migraine did not respond within 2 hours after first dose or if responded and recurred then a second dose was permitted within 24 hours after first dose.
Lasmiditan 200mg	Lasmiditan	Participants received oral dose of 200mg Lasmiditan with in four hours of onset of migraine attack. If the migraine did not respond with in 2 hours after first dose or if responded and recurred then a second dose was permitted within 24 hours after first dose.

Primary Outcome Measures

Name	Time	Method
Number of Participants With at Least 1 Treatment Emergent Adverse Event	Up to 12 months	An AE with an onset on or within 48 hours after a dose of study drug, or an event that worsened in intensity within 48 hours of a dose of study drug was considered a treatment-emergent adverse event (TEAE). A summary of serious adverse events (SAEs) and other non-serious adverse events (AEs), regardless of causality, were reported in the Reported Adverse Events module.

Secondary Outcome Measures

Name	Time	Method
Percentage of Migraine Attacks With Most Bothersome Symptom-Free (MBS) at 2 Hours After Dose	Up to 12 months	MBS-free, defined as the absence of the associated symptom of migraine (nausea, phonophobia, and/or photophobia) at 2 hours postdose that was identified predose as the most bothersome symptom.
Percentage of Migraine Attacks With Pain Freedom (PF) at 2 Hours After Dose	Up to 12 months	Pain freedom is defined as a reduction in headache severity from mild (1), moderate (2), or severe (3) at baseline to none (0).
