The reason for this 12-month, open-label study is to see if the study drug lasmiditan is safe and effective for the intermittent acute treatment of migraine in children aged 6 to 17. The study will last about 12 months and may include up to 7 visits.

Number of Participants With at Least One Treatment Emergent Adverse Events (TEAEs)
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.
Time frame: Baseline up to 12-month treatment period (Up to 12 Months)
Number of Participants With Discontinuations Due to Adverse Events (AEs)
Participants who discontinued due to adverse events were reported in this outcome measure.
Time frame: Baseline up to 12-month treatment period (Up to 12 Months)
Percentage of Treated Migraine Attacks With Pain Freedom (PF) at 2 Hours Post-Dose
Pain relief at 2 hours post-dose was defined as having a pain intensity of none or mild at that time point. The 5-Face Pain Scale is a single-item, self-report tool assessing pain intensity along a single domain. Participants select one face from five options to represent their current pain level; no score aggregation or calculation is performed- the selected face directly represents the pain intensity score. The five faces correspond to: Face 1= none, Face 2= mild, Faces 3-4= moderate (both faces represent moderate pain as defined by this scale, with Face 3 reflecting lower-moderate and Face 4 reflecting upper-moderate intensity) and Face 5= severe. The scale ranges from a minimum value of 1 (no pain) to a maximum value of 5 (severe pain); higher scores indicate worse outcome. Participants with a reduction in baseline pain from moderate (Faces 3 or 4) or severe (Face 5) to no pain (Face 1) at 2 hours post-dose were considered to have achieved pain freedom.
Time frame: 2 hours post-dose (for each treated migraine attack, up to 12-month treatment period)

Participants with reduction from baseline moderate (Faces 3 or 4) or severe (Face 5) to mild or none (Face 1 or 2), or those reported as asleep at 2 hours post-dose were considered to have achieved pain relief.
Time frame: 2 hours post-dose (for each treated migraine attack, up to 12-month treatment period)
Percentage of Treated Migraine Attacks With Freedom From Most Bothersome Symptom (MBS) at 2 Hours After Dose
Participants identified one pre-specified most bothersome symptom (MBS) prior to each migraine dose from three options (nausea, photophobia, or phonophobia). The same pre-selected MBS was assessed at baseline (pre-dose) and at 2 hours post-dose using a binary scale recorded via electronic diary (e-Diary), where "Yes" = MBS present and "No" = MBS absent. MBS freedom was defined as a change from MBS present ("Yes") at baseline to MBS absent ("No") at 2 hours post-dose. A response of "No" at 2 hours post-dose represents a favorable outcome. Only migraine attacks in which the MBS was reported as present at baseline were included in the analysis. No aggregation, transformation, or total score calculation was performed, as this is a single-item dichotomous assessment per attack.
