Food-Effect Study in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the effect of food on the pharmacokinetics (PK) of a single dose of lasmiditan in healthy participants.

Detailed Description
-----------------
An open-label, cross-over, two-period, randomized, sequential study in order to investigate the effect of food on the pharmacokinetics of lasmiditan 200 mg. Two single doses of lasmiditan will be administered with the participants in fed and fasted states.

Must be able to understand the requirements of the study and must be willing to comply with the requirements of the study. Exclusion Criteria: Any medical condition or clinical laboratory test which in the judgment of the Investigator makes the participant unsuitable for the study. Pregnant or breast-feeding women.

History within the previous 3 years or current evidence of abuse of any drug, prescription or illicit, or alcohol; a positive urine screen for drugs of abuse or alcohol. History of orthostatic hypotension with or without syncope. At imminent risk of suicide (positive response to question 4 or 5 on the Columbia-Suicide Severity Rating Scale [C-SSRS]) or had a suicide attempt within 6 months prior to screening. Participation in any clinical trial of an experimental drug or device in the previous 30 days. Positive Hepatitis C antibody, Hepatitis B surface antigen, or positive human immunodeficiency virus (HIV) antibody. Donated plasma in the 7 days or blood in the 3 months preceding study drug administration. Inability to communicate well with the Investigator and study staff (i.e., language problem, poor mental development or impaired cerebral function). Inability to fast or consume the food provided in the study. Relatives of, or staff directly reporting to, the Investigator.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics - Cmax (ng/mL) | This study was designed to estimate the relative bioavailability of lasmiditan 200 mg in the fed state relative to the fasted state. For each primary pharmacokinetic endpoint, i.e., Area under concentration curve (time zero to last, time zero to infinity), Maximum concentration, point estimates and corresponding 90% confidence intervals were constructed. Duration of the study was approximately 5 weeks, including up to 3 weeks for screening and 16 days on study (2 - 3 day dosing periods, 6 day washout period and follow-up). | Sequential timepoints on each dosing day pre-dose to 30 h (timepoints - pre-dose and then 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24 and 30 hours post dose) | 
| Pharmacokinetics - Tmax (Hours) | This study was designed to estimate the relative bioavailability of lasmiditan 200 mg in the fed state relative to the fasted state. For each primary pharmacokinetic endpoint, i.e., Area under concentration curve (time zero to last, time zero to infinity), Maximum concentration, point estimates and corresponding 90% confidence intervals were constructed. Duration of the study was approximately 5 weeks, including up to 3 weeks for screening and 16 days on study (2 - 3 day dosing periods, 6 day washout period and follow-up). | Sequential timepoints on each dosing day pre-dose to 30 h (timepoints - pre-dose and then 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24 and 30 hours post dose) | 
| Pharmacokinetics - AUC0-t (ng.h/mL) | This study was designed to estimate the relative bioavailability of lasmiditan 200 mg in the fed state relative to the fasted state. For each primary pharmacokinetic endpoint, i.e., Area under concentration curve (time zero to last, time zero to infinity), Maximum concentration, point estimates and corresponding 90% confidence intervals were constructed.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety. Safety Measurements Include Physical Exams, Vital Signs, ECGs, Clinical Laboratory Assessments, AEs, Columbia Suicide Severity Rating Scale (C-SSRS). | Safety was evaluated in all participants (n=30) under the fasted condition and the fed condition, not by sequence of assigned cross-over (fed/fasted or fasted/fed). The number of unique subjects with an AE and the number of events are provided. | Duration of study- From Screening (signing informed consent form) to End-of-Study   15 days | 
| Tolerability | Tolerability was defined as the number of participants that did not withdraw from the study early due to adverse events. | 15 days |
