Study to Assess Absolute Bioavailability (ABA) of TAK-906 and to Characterize Mass Balance, Pharmacokinetics (PK), Metabolism, and Excretion of [14C]-TAK-906 in Healthy Male Participants

Phase 1

Completed

Conditions: Healthy Volunteers

Interventions: Drug: TAK-906 Oral Capsule
Drug: [14C]-TAK-906 Intravenous Infusion
Drug: [14C]-TAK-906 Oral Solution

Registration Number: NCT04454918

Lead Sponsor: Millennium Pharmaceuticals, Inc.

Brief Summary: The purpose of this study is to determine ABA of TAK-906 following single oral (capsule) administration of 50 milligram (mg) of TAK-906 and single intravenous (IV) microtracer dose administration of 100 microgram (μg) (approximately 1 microcurie \[μCi\]) of \[14C\]-TAK-906 in Period 1 (ABA), and to determine the mass balance of TAK-906 in urine and feces following a single oral (solution) administration of 50 mg (approximately 100 μCi) of \[14C\]-TAK-906 in Period 2 (absorption, distribution, metabolism, and elimination \[ADME\]).

Detailed Description: The drug being tested in this study is called TAK-906. The study will determine ABA in Period 1, and ADME, and mass balance of TAK-906 after single oral administration in Period 2 in healthy adult male participants. Plasma and urine samples will be collected for PK determination; plasma, whole blood, urine, and feces samples will be collected for total radioactivity (TRA) determination; and plasma, urine, and feces samples will be collected to characterize the metabolite profiles of TAK-906.

The study will enroll approximately 6 participants. The study is designed to consist of 2 periods: Period 1 (ABA study period) and Period 2 (ADME study period). In Period 1 (ABA study period), all participants will receive single unlabeled oral 50 mg dose of TAK-906 as capsule followed by microdose of 100 μg (approximately 1 μCi) \[14C\]-TAK-906 as intravenous infusion followed by a washout period of at least 7 days before the dose in Period 2. In Period 2 (ADME study period), all participants will receive a single dose of 50 mg (approximately 100 μCi) \[14C\]-TAK-906 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.

Unable to refrain from or anticipates the use of:
- Any drug, including prescription and non-prescription medications, herbal remedies, or vitamin supplements within 14 days prior to the first dosing and throughout the study. Acetaminophen (up to 2 g per 24 hour period) and Milk of Magnesia® (that is, magnesium hydroxide [less than or equal to (<=) 60 mL per day after Day 3 in Period 1 and after Day 8 in Period 2]) may be permitted during the study, only after dosing, if necessary to treat adverse events (AEs). Additional administration of Milk of Magnesia® may be administered on other days at discretion of the Investigator.
- Any drugs known to significantly affect the absorption, distribution, metabolism or elimination of TAK-906 within 28 days prior to the first dosing and throughout the study. Appropriate sources (example, Flockhart Table TM) will be consulted to confirm lack of PK/pharmacodynamics interaction with study drug.
