5. Study Description

Brief Summary
This study is a Phase 1, single-center, open-label study to investigate the absorption, metabolism, and excretion of BTZ-043 after a single oral administration of 500 mg BTZ-043 containing 3.7 MBq of [14C]BTZ-043 in 4 healthy adult male subjects
Detailed Description
A total of 4 evaluable subjects completing all procedures are required. Six (6) subjects will be enrolled in the cohort in order to have 4 evaluable subjects. The study will consist of a screening period (Day -21 to -2), a baseline period (Day -1), a single dose treatment on Day 1 with a minimum of 96 hours (=4 days) post dose in-house observation period (Days -1 up to afternoon Day 5), and a follow-up visit 30 days (±2 days) after the [14C]BTZ-043 dose. Subjects will be administered a single 500 mg [14C]BTZ-043 dose as drinking suspension. Subjects will be confined to the clinical site for at least 96 hours following drug administration (ie, afternoon of Day 5). During this time, blood, feces, and urine samples for measurement of [14C]BTZ-043 and metabolites will be collected. The subjects will be released from the clinic approximately 96 hours to 168 hours after dose administration and upon satisfactory recovery of radioactivity (at least 90%) approved by the Sponsor's scientific advisor after consulation of the Sponsor.
