A Study of Lasmiditan (LY573144) Treatment in Children Aged 6 to 17 With Migraine

Pain freedom at 2 hours post-dose was defined as having a pain intensity of none at that time point. Pain was measured on a 5-face pain scale, with following scores: 1= none, 2= mild, 3 and 4= moderate, 5= severe. Participants with a reduction in baseline pain as measured on a 5-Face Pain Scale from moderate (Faces 3 and 4) or severe (Face 5) to no pain (Face 1) were considered as pain freedom. 5-Face Pain Scale; minimum value: 1 (no pain); maximum value: 5 (severe pain); higher scores indicate worse outcome.

Pain relief at 2 hours post-dose was defined as a pain intensity of none or mild at that time point. Pain was measured on a 5-face pain scale, with following scores: 1= none, 2= mild, 3 and 4= moderate, 5= severe. Participants with a reduction in baseline pain from moderate (Faces 3 and 4) or severe (Face 5) to mild or no pain (Face 1 or 2) or patient is asleep were considered to have pain relief. 5-Face Pain Scale; minimum value: 1 (no pain); maximum value: 5 (severe pain); higher scores indicate worse outcome.

MBS freedom was defined as MBS reported before dosing that was absent post-dose. MBS included nausea, photophobia, or phonophobia. MBS were measured using a binary scale (Yes/No) using electronic diary (e-Diary) at 2-hours post-dose. Participants who captured as "No" (MBS absent) were considered to have freedom from MBS.

Nausea status was measured as absent or present in the e-Diary. Freedom from nausea was defined as nausea absent. Participants who captured as "No" (Nausea absent) were considered to have freedom from nausea.

Photophobia (sensitivity to light) status was measured as absent or present in the e-Diary. Freedom from photophobia was defined as photophobia absent. Participants who captured as "No" (Photophobia absent) were considered to have freedom from photophobia.

Phonophobia (sensitivity to sound) status was measured as absent or present in the e-Diary. Freedom from phonophobia was defined as phonophobia absent. Participants who captured as "No" (phonophobia absent) were considered to have freedom from phonophobia.

Sustained pain freedom from 2 through 24 hours post-dose was defined as a pain intensity of none at all time points with 24 hours post-dose. Pain intensity was assessed using a 5-Face Pain Scale (1 = none, 2 = mild, 3 or 4 = moderate, 5 = severe). Participants with score of 1 (with no pain) through 2 to 24 hours post-dose with no use of rescue medication or no relapse within the 24 hours of the initial treatment were considered to have sustained pain freedom. 5-Face Pain Scale; minimum value: 1 (no pain); maximum value: 5 (severe pain); higher scores indicate worse outcome.

Rescue medication was permitted after completion of the 2-hour assessment if the migraine did not respond (participant was not pain free).

Sustained pain freedom from 2 through 48 hours post-dose was defined as a pain intensity of none at all time points with 48 hours post-dose. Pain intensity was assessed using a 5-Face Pain Scale (1 = none, 2 = mild, 3 or 4 = moderate, 5 = severe). Participants with score of 1 (with no pain) through 2 to 48 hours post-dose with no use of rescue medication or no relapse within the 48 hours of the initial treatment were considered to have sustained pain freedom. 5-Face Pain Scale; minimum value: 1 (no pain); maximum value: 5 (severe pain); higher scores indicate worse outcome.

Rescue medication was permitted after completion of the 2-hour assessment if the migraine did not respond (participant was not pain free).

Disability was assessed by the level of interference with normal activities using an electronic diary. Participants rated how much their migraine interfered with usual activities (e.g., play, schoolwork, or other work) using a 4 point numeric rating scale, where 0 = not at all, 1 = a little, 2 = a lot, and 3 = complete interference (required bed rest). No Disability was defined as the first time point at which a score of 0 (no interference) was reported. 4-Point Numeric Rating Scale; minimum value: 0 (not at all); maximum value: 3 (complete interference/bed rest required); higher scores indicate worse outcome. Percentages for each response category were estimated using a repeated-measures logistic mixed-effects model (treatment + time + age group + treatment*time + preventive treatment), not as a simple count divided by the Overall Number of Participants Analyzed (N). As a result, individual percentages may not correspond to a whole number of participants out of N.

Acceptability of the lasmiditan oral formulation (single tablet) was assessed using an electronic diary at the 24 hour post dose assessment. Participants were asked to report their experience of swallowing the study medication by responding to the question: "Think about the experience of swallowing the study medicine. How easy or hard was it for you to swallow one of the pills?" Responses were recorded on a 5 point ordinal scale: Very easy, Easy, Neither easy nor hard, Hard, or Very hard. 5-Point Ordinal Scale; minimum value: 1 (Very Easy); maximum value: 5 (Very Difficult); higher scores indicate worse outcome.
