Mass Balance and Biotransformation Study of [14C]DBPR108 in Human
December 13, 2021 updated by: CSPC ZhongQi Pharmaceutical Technology Co., Ltd.
A Clinical Study to Evaluate the Absorption, Metabolism, and Excretion of [14C]DBPR108 in Chinese Healthy Adult Male Subjects- Mass Balance and Biotransformation Study of [14C]DBPR108 in Human
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.
Study Overview
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.
