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

12. oktober 2016 opdateret af: Sanwa Kagaku Kenkyusho Co., Ltd.

An Open-Label, 2-Part Sequential Dose Study Designed to Assess the Absolute Bioavailability, Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C]-SK-1404 Administered to Healthy Male Subjects

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

Detaljeret beskrivelse

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.
