A Study of Lasmiditan in Healthy Japanese and Caucasian Participants

Safety, Tolerability, and Pharmacokinetics of Lasmiditan in Healthy Japanese and Caucasian Subjects

The main purpose of this study is to evaluate the safety and tolerability of lasmiditan in healthy Japanese and Caucasian participants. The study will also investigate how much lasmiditan gets into the bloodstream and how long it takes the body to get rid of lasmiditan when given to Japanese and Caucasians. The study will last up to 47 days for each participant.

Inclusion Criteria:

• Have known allergies to lasmiditan, related compounds or any components of the formulation of lasmiditan
• Have previously received the investigational product in this study, withdrawn from this study, or received lasmiditan in any other study investigating lasmiditan
• Have an abnormal supine blood pressure at screening.
• Have a history of syncope, presyncope, uncontrolled vertigo, postural dizziness, or a risk of falls, as judged to be clinically significant by the investigator, or have orthostatic decreases in supine blood pressure of >20 millimeters of mercury (mmHg), or have orthostatic decreases in diastolic blood pressure of >10 mmHg at screening.
• Are women who are pregnant, lactating, or have a positive pregnancy test at screening or admission to the clinical research unit (CRU)
