Study Overview
Brief Summary
This is a single-center, open-label phase I clinical study to evaluate the mass balance and biotransformation pathways of [14C]DBPR108 in Chinese healthy adult male subjects, to reveal the overall pharmacokinetic characteristics of DBPR108 in human body, and to provide a reference for the rational administration.
Detailed Description
This study will evaluate the mass balance and pharmacokinetics of DBPR108 in approximately 6 healthy male subjects receiving a single oral 100 mg dose of DBPR108 containing approximately 150 µCi of [14C]- DBPR108. This study consists of a screening period (Day -7 to Day -2), a baseline period (Day -1), a treatment period, and a follow-up visit period.

- •History of drug abuse, or positive urine drug screen at screening;
- •Subjects who have a habitual consumption of grapefruit juice or excessive amounts of tea, coffee and/or caffeinated beverages (such as coffee, tea, cola, chocolate, energy drinks), and unable to quit during the study period;
- •Workers engaged in long-term exposure to radioactive conditions, or have had significant radiation exposure (≥2 chest/abdominal CT scans, or ≥3 other types of X-rays) or participated in the radiopharmaceuticals labeling test within 1 year prior to the study;
- •Subjects who have fertility or sperm donation plans, or do not agree to use strict contraceptive methods during the study period and within 1 year after the completion of the study;
- •Blood donation (or blood loss) ≥400 mL within 3 months, or receiving whole blood transfusions or erythrocyte suspension transfusions within 1 month prior to the screening;
