Absorption, Metabolism and Excretion of [14C]-Lasmiditan - Single Oral Dose Administration

A Phase 1 Study to Investigate the Absorption, Metabolism, and Excretion of [14C]-Lasmiditan Following Single Oral Dose Administration in Healthy Male and Female Subjects

This study will be an open-label, nonrandomized, absorption, metabolism, and excretion study of [14C]-lasmiditan administered as a 200-milligrams (mg) (approximately 100 microcuries[µCi]) oral solution to 8 healthy males and females, following at least a 10 hour fast from food to assess the pharmacokinetics (PK), metabolism, and routes and extent of elimination of a single oral dose of 200 mg (approximately 100 µCi) [14C] lasmiditan in healthy males and females.

• Any acute or chronic condition that, in the opinion of the Investigator (or designee), would limit the particpant's ability to complete or participate in this clinical study
• Any other unspecified reason that, in the opinion of the Investigator (or designee) or Sponsor, makes the participant unsuitable for enrollment
