A Study to Access Safety, Tolerability, Pharmacokinetics(PK) and Pharmacodynamics(PD) of Orally Administered GCC-4401C in Healthy Volunteers

A Phase I, Randomized, Double-blind, Placebo-controlled, Single and Multiple Sequential Ascending Dose Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Orally Administered GCC-4401C in Healthy Males

The purpose of this study is to evaluate the safety, tolerability and Pharmacokinetics/Pharmacodynamics of multiple doses of GCC-4401C in healthy male subjects.

Study Overview

• Status: Completed
• Conditions: Healthy Volunteers
• Intervention / Treatment: Drug: GCC-4401C; Drug: Rivaroxaban; Drug: Placebo

Detailed Description

The primary objective is to investigate the safety, tolerability, and pharmacokinetics of multiple doses of GCC-4401C in healthy male subjects.

Forty-six subjects are planned for enrollment. The study consists of five cohorts (10 mg, 20 mg, 40 mg, 60 mg, and 80 mg) with eight subjects per cohort. In the 20 mg cohort, six additional subjects will receive rivaroxaban (Xarelto®) 20 mg as an active comparator in open-label fashion. Within each of the five cohorts, six subjects will be randomized to GCC-4401C and two subjects will be randomized to placebo.

The secondary objectives of this study are

• To characterize the single dose safety, tolerability, and PK after oral administration of GCC-4401C in healthy male subjects.
• To characterize the multiple dose pharmacodynamics after oral administration of GCC-4401C in healthy male subjects.
• To determine an appropriate dose range and dosing regimen of oral GCC-4401C for subsequent clinical trials.
• To compare the PK and PD of GCC-4401C with an active rivaroxaban (Xarelto®)group at 20 mg in healthy male subjects.
