Bioavailability of [14C]-SK-1404 ADME & IV Microtracer Study


Open to: Male

Age: 30 Years - 65 Years

Medical Conditions


This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.

The primary objectives of the study are: - To determine the absolute bioavailability of SK-1404 - To assess the mass balance recovery after a single oral (PO) dose of carbon-14 (14C)-SK-1404 - To provide plasma, urine and faecal samples for metabolite profiling and structural identification The secondary objectives of the study are: - To determine the routes and rates of elimination of [14C]-SK-1404 - To identify the chemical structure of each metabolite with an exposure (AUC) of more than 10% of circulating total radioactivity - To explore the intravenous (IV) pharmacokinetics (PK) of [14C]-SK-1404 - To further explore the PO PK of SK-1404 - To provide additional safety and tolerability information for SK-1404

This is a single-centre, 2-part, open-label, non-randomised, sequential, single dose study in healthy male subjects. It is planned to enrol a single cohort of 6 healthy male subjects who will participate in Parts 1 and Part 2 of the study. In Part 1, each subject will receive a single PO dose of SK-1404 followed by an IV microtracer dose of [14C]-SK-1404. In Part 2, each subject will receive a single PO dose of [14C]-SK-1404.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

Intervention Type : Drug
Intervention Description : In Part 1, each subject will receive a single PO dose of SK-1404 followed by an IV microtracer dose of [14C]-SK-1404.

Intervention Arm Group : [14C]-SK-1404
