A Study to Assess Absolute Bioavailability (ABA) of TAK-831 and to Characterize Mass Balance, Pharmacokinetics (PK), Metabolism, and Excretion of [14C]TAK-831 in Male Healthy Participants

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

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.

Who can join

Age: 19 and older, up to 55. Sex: male. Healthy volunteers: accepted.

You may qualify if…

• Weighs at least 45 kilogram (kg) and body mass index (BMI) greater than or equal to (>=) 18.0 and less than (˂) 32.0 kilogram per square meter (kg/m\^2) at screening.

You may not qualify if…

• Seated blood pressure is less than 90/40 millimeter of mercury (mmHg) or greater than 140/90 mmHg at screening.
• Seated heart rate is lower than 40 beats per minute (bpm) or higher than 99 bpm at screening.
• Estimated creatinine clearance <80 milliliter per minute (mL/min) at screening.
• Has tattoo(s) or scarring at or near the site of intravenous infusion or any other condition which may interfere with infusion site examination, in the opinion of the Investigator.
• Has infrequent bowel movements (less than approximately once per day) within 30 days prior to first dosing.
• Has received radiolabeled substances or has been exposed to radiation sources within 12 months of first dosing or is likely to receive radiation exposure or radioisotopes within 12 months of first dosing such that participation in this study would increase their total exposure beyond the recommended levels considered safe (that is weighted annual limit recommended by the International Commission on Radiological Protection [ICRP] of 3000 milli roentgen equivalent man [mrem]).
• Has been on a diet incompatible with the on-study diet, in the opinion of the Investigator or designee, within the 30 days prior to the first dosing and throughout the study.
• Donation of blood or significant blood loss within 56 days prior to the first dosing.
• Plasma donation within 7 days prior to the first dosing.
