A Study of the Absorption, Metabolism and Excretion of [14C]XZP-3621 in Human
- Registration Number
- NCT05836805
- Lead Sponsor
- Xuanzhu Biopharmaceutical Co., Ltd.
- Brief Summary
This non-randomized, single group, open-label study will investigate the mass balance, routes of elimination, pharmacokinetics, metabolism, safety and tolerability of a single oral dose of \[14C\]XZP-3621 in healthy volunteers.
- Detailed Description
This open-label, radiolabeled, single 400-mg dose study in approximately 6 healthy male volunteers has been designed to further the understanding of human metabolism of XZP-3621.
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 performed baseline examination and trained on procedures such as medicine-taking, PK blood collection, urine and fecal collection, etc., to ensure that the procedures can be performed according to the protocols and standard operating procedures. And after an overnight fast of at least 10 h, 30 minutes afer a standard meal, subjects will receive a single oral dose of 400 mg (200 μCi) of \[14C\]XZP-3621 as an oral suspension. Water will be banned from 1 hour pre-dose to 1 hour post-dose (excluding when taking the medicine) and food will be banned within 4 hours post-dose.
Metabolic profiling of radiolabeled components will be performed on pooled plasma samples as well as on cumulative urine and feces excreted until Day 14 postdose or until one of the early release criteria is met. The early release criteria are: 1) recovery in excreta of at least 80% of administered radioactivity, or 2) less than 1% of administered radioactivity being recovered in excreta from two consecutive days (ie, total for urine + feces should be \<1% on 2 consecutive days).

Group Intervention Description [14C]XZP-3621 [14C]XZP-3621 Eligible healthy 6 volunteers will receive a single oral dose of 400 mg/200 µCi \[14C\]XZP-3621 administered by mouth, as a suspension solution.
- Primary Outcome Measures
Name Time Method Total recovery of radioactivity in urine and feces Assessments will be made up to 19 days post dose Calculate the total radioactivity in urine and feces based on the radioactivity concentration of each sample.
Radioactivity concentration of each plasma sample Assessments will be made up to 19 days post dose Use liquid scintillation counter to evaluate Radioactivity concentration of each plasma(DPM/ml) sample
Metabolic profiling for XZP-3621 will be determined in plasma, urine and fecal samples Assessments will be made up to 19 days post dose Percent (%) of each radiolabeled drug-related material (parent and each metabolite) will be determined in plasma, urine and feces.
Maximum exposure in plasma will be determined for XZP-3621, XZP-5089 metabolite and total radioactivity Assessments will be made up to 19 days post dose Cmax (maximum observed plasma concentration) will be reported directly from each analyte's data
