A Clinical Study to Evaluate Safety, Tolerability and Pharmacokinetics of Oral ZYGK1 in Healthy Volunteers

A Randomized, Double Blind Placebo Controlled Phase 1 Clinical Study to Evaluate the Safety, Tolerability and Pharmacokinetics of ZYGK1, a Novel Glucokinase Activator, Following Oral Administration in Healthy Volunteers

The purpose of this study is to determine (1) whether ZYGK1 is safe and well tolerated, (2) the pharmacokinetics (what body does to ZYGK1) and (3) pharmacodynamics (what drugs does to the body) in the healthy and diabetic subject.

Study Overview

• Status: Suspended
• Conditions: Diabetes
• Intervention / Treatment: Drug: Placebo; Drug: ZYGK1

Detailed Description

This study will be a randomized, double blind, placebo controlled study and is divided into four plans:

1. Plan I: Single Ascending Dose (SAD) Study
2. Plan II: Multiple Ascending Dose (MAD)Study
3. Plan III: Gender Effect study
4. Plan IV: Food Effect study

First Plan I, Plan III and Plan IV will be conducted in healthy volunteers. After reviewing the results, decision shall be taken whether the multiple ascending doses shall be studied in healthy human volunteers or in subjects with type 2 diabetes.
