Official title

A Phase 1 Study to Assess Absolute Bioavailability of TAK-831 and to Characterize Mass Balance, Pharmacokinetics, Metabolism, and Excretion of [14C]TAK-831 in Male Healthy Subjects

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to determine ABA of TAK-831 following a single microdose intravenous administration of 50 microgram (μg) (approximately 1 microcurie \[μCi\]) \[14C\]TAK-831 and a single oral administration of 500 milligram (mg) TAK-831 tablets in Period 1, and to assess the mass balance, characterize the PK of TAK-831 in plasma and urine, and total radioactivity concentration equivalents in plasma and whole blood following a single oral suspension dose of 500 mg (approximately 100 μCi) \[14C\]TAK-831 in Period 2.
