A Phase 1 Study of the Absorption, Metabolism, and Excretion of CYC065 in Healthy Male Subjects
Study Details
Study Description
Brief Summary
This will be a Phase 1, open-label, single dose study of the Absorption, Metabolism, and Excretion of CYC065 in healthy male subjects.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Early Phase 1 |
Detailed Description
Potential subjects will be screened to assess their eligibility to enter the study within 28 days prior to the dose administration. Subjects will be admitted into the study site on Day -1 and be confined to the study site until at least Day 8 (168 hours post dose). On Day 1, subjects will receive a single oral dose of [14C]-CYC065. Subjects will be discharged if the following discharge criteria are met: plasma radioactivity levels below the limit of quantitation for 2 consecutive collections, ≥90% mass balance recovery, and ≤1% of the total radioactive dose is recovered in combined excreta (urine and feces) in 2 consecutive 24-hour periods. If discharge criteria are not met by Day 8, subjects will remain in the study site until all discharge criteria are met up to a maximum of Day 15.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Up to 8 subjects will be enrolled and studied as a single group The purpose of this study is to determine the absorption, metabolism, and excretion (AME) of [14C]CYC065 and to characterize and determine, where possible, the metabolites present in plasma, urine, and feces in healthy male subjects following a single oral administration. |
