Description of intervention(s) / exposure
This is a blinded, crossover study. There are two treatment arms: active and placebo, and two treatment periods. Patients are given paper diaries to record daily details of headaches and migraine headaches, and to capture details of other medications. Patients are only given a single dose of active IMP to treat one migraine, and a single dose of placebo to treat one migraine. Patients will only treat two migraines in total across the two treatment periods.
Patients will be randomly assigned to receive either receive active or placebo in their first treatment period, and after a 48 hour washout, will be crossed over to receive the alternative treatment for treatment period 2. The patients are not supervised during dosing, but are sent home from clinic at the start of each treatment period with the active or placebo, and instructions from the clinic staff about the timing of the dosing, and how to complete their diaries.
The active treatment is a single dose of two 30 mg capsules of LAT8881 which patients are to take at the onset (within one hour from the onset of pain) of one migraine headache of moderate to severe intensity.
Total single dose of IMP: 60 mg LAT8881
Intervention code [1] 315618 0
Treatment: Drugs
Comparator / control treatment
Two capsules of matching placebo to be taken at the onset (within one hour from the onset of pain) of a migraine headache of moderate to severe intensity. The placebo capsules match the active capsules, but instead of LAT8881, they contain additional mannitol.
Control group
Placebo

Outcomes
Primary outcome [1] 321453 0
To evaluate the effect of oral LAT8881 on migraine headache compared with placebo, when assessed by the headache severity on an 11-point Numeric Rating Scale (NRS).
Timepoint [1] 321453 0
Change in migraine headache pain score, using an 11-point NRS, (0 = none, 10 = worst imaginable), from the time of dosing (t = 0 min) to 0.5, 1.0, 1.5, 2, 4, 8 and 24-hours post dose.
Secondary outcome [1] 375003 0
To evaluate the effect of oral LAT8881 on migraine associated symptoms compared with placebo, when assessed by the change in symptoms based on a 11 point Likert scale.

Statistical methods / analysis
No formal statistical sample size estimation has been performed due to the exploratory nature of this study. Rather the sample size is based on clinical and practical considerations.
The safety population includes all subjects who receive at least one dose of IMP and will be the population used for the analysis of safety endpoints. The full analysis set (FAS) population will be used to present demographic and other baseline characteristics and summaries of efficacy endpoints. A per-protocol (PP) population will be used as the primary population for efficacy analyses and to analyse exploratory endpoints. The PP population will be based on IMP exposure, including the time of any episodes of vomiting and major protocol deviations.
As this is a Phase IIa proof of concept study, no formal statistical hypotheses are being specified although some may be investigated as part of the data presentation. A p-value of <0.05 will be declared statistically significant. Treatment period order will be ignored in any treatment comparisons. Results will be presented in a descriptive format by treatment within each treatment period and overall. Treatment comparisons will take into account the paired nature of the treatment responses where feasible.

Summary
Brief summary
The main aim of this crossover study is to see whether LAT8881 is safe and effective in relieving acute migraine headaches. Subjects enrolled in the study will be randomised to receive Investigational Medicinal Product (LAT8881 60 mg or placebo), to be taken at the onset of a migraine headache of moderate to severe intensity. Subjects will be given a single dose of IMP, to treat one migraine headache. After treatment of one migraine headache and a 48 hour washout period, the subject will return to the clinic for re-evaluation and crossover to the second treatment.
