Brief Summary

A randomised, placebo controlled Phase I study to investigate investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of Y14 in adult subjects.

Detailed Description

Objectives:

Primary Objective

• To investigate the safety and tolerability of single doses of Y14 in overweight/obese but otherwise healthy male subjects.
• To investigate the safety and tolerability of multiple doses of Y14 in overweight/obese male subjects with normal glucose tolerance, Type 2 diabetes or prediabetes.

Secondary Objectives

• To assess the pharmacokinetic (PK) profile of single doses of Y14 in overweight/obese but otherwise healthy male subjects.
• To assess the PK profile of multiple ascending doses of Y14 in overweight/obese male subjects with normal glucose tolerance, Type 2 diabetes or prediabetes.

Exploratory Objective

• To investigate the effects of multiple doses of Y14 on food consumption, body weight and glucose tolerance in overweight/obese male subjects with normal glucose tolerance, Type 2 diabetes or prediabetes.

Eligibility Criteria

Inclusion Criteria

1. Adult males aged 18 to 65 years inclusive with BMI between 25.0 and 38.0 kg/m2 inclusive;

2. (PART B only) Subjects who have normal glucose tolerance, Type 2 diabetes, impaired glucose tolerance or impaired fasting glucose according to WHO 2006 and 2011 criteria;

3. Subjects who are otherwise healthy enough to participate, as determined by pre-study medical history, physical examination and 12-lead ECG;

4. Subjects whose clinical laboratory test results are either within the normal range or if outside this range the abnormalities are judged to be not clinically relevant and are acceptable to the Investigator;
