About

This is a single-center, open-label, single-dose phase I study to investigate the absorption, metabolism and excretion of [14C] D-0316 in healthy Chinese male subjects. The study will be conducted into two steps：Firstly, 2 subjects are enrolled in to participate in the pilot study to grope for the completion date of plasma, urine and feces sampling on the 3rd day post-dose and onwards. Then, the collection time of blood and excreta samples (urine and feces) from the subsequent 2-4 subjects will be adjusted according to the pilot study

Full description

Subjects who had signed informed consent and meet inclusion criteria and no exclusion criteria are admitted to Phase I Clinical Unit two days prior to dosing (D-2). On the morning of Day 1 before dosing, subjects will be transferred to nuclear medical ward. And after an overnight fast of at least 10 h, subjects will receive a single oral dose of 75 mg (50 μCi) of [14C]D-0316 as an oral suspension. Then, after two days of the dosing, subjects will be transferred back to Phase I Clinical Unit ward and confined to this unit until blood or excreta sampling and safety monitoring at the designated time points or intervals are complete

Enrollment: 4 patients

Sex: Male

Ages: 18 to 50 years old

Volunteers: Accepts Healthy Volunteers
