Study to Assess Absolute Bioavailability of TAK-935 (OV935) and to Characterize Mass Balance, Pharmacokinetics, Metabolism, and Excretion of [14C]TAK-935 (OV935) in Healthy Male Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine absolute bioavailability (ABA) of TAK-935 (F) following a single microdose intravenous (IV) administration of 50 microgram (μg) (approximately 1 microcurie [μCi]) [14C]TAK-935 and a single oral administration of 3×100 mg milligram (mg) TAK-935 tablets in Treatment Period 1, and to assess the mass balance, characterize the pharmacokinetics (PK) of TAK-935 and metabolite [M-I (N-oxide)] in plasma and urine, and total radioactivity concentration equivalents in plasma and whole blood following a single oral administration of 300 mg (approximately 100 μCi) [14C]TAK-935 in Treatment Period 2.

Detailed Description
-----------------
The drug being tested in this study is called TAK-935 (also known as soticlestat/OV935). The study determines ABA in Treatment Period 1, and the absorption, metabolism, excretion, and mass balance of TAK-935 after single oral administration in Treatment Period 2 in healthy adult male participants, by collecting plasma, urine, and feces samples for drug concentration analysis, and plasma, whole blood, urine, and fecal samples for total radioactivity analysis and metabolic profiling. The study will enroll approximately 6 healthy adult male participants. The study is designed to consist of 2 periods: Treatment Period 1 (ABA Study Period) and Treatment Period 2 (Absorption, Distribution, Metabolism, and Elimination [ADME] Study Period). In Treatment Period 1, all participants will receive a single unlabelled oral dose of TAK-935 as 3×100 mg tablets and a microdose IV infusion of 50 μg (approximately 1 μCi) [14C]TAK-935, followed by a Washout Period of 7 days before the dose in Treatment Period 2. In Treatment Period 2, all participants will receive a single dose of 300 mg (approximately 100 μCi) [14C]TAK-935 as an oral solution. This single center trial will be conducted in the United States. The overall time to participate in this study is approximately 65 days including Screening Period. Participants will be contacted approximately 30 days after the last dose of study drug for a follow-up assessment. This compound was transferred to Takeda and acquired on 29 March 2021. This registration is retrospective due to the transfer of ownership.
