Brief Summary

The purpose of this study is to see if GSK1292263 is safe and well-tolerated when administered to type 2 diabetics, and to get preliminary information about whether it may be effective in the treatment of type 2 diabetes.

Detailed Description

Data from this study will be used to assess the potential of GSK1292263 as a treatment for T2DM, and will aid the design and dose selection of future studies of longer duration in T2DM subjects that will evaluate GSK1292263 alone or in combination with other anti-diabetic drugs.

Conditions

Diabetes Mellitus, Type 2

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Primary Study Purpose: OTHER
• Blinding Strategy: DOUBLE

Study Groups

Part A

Part A (Cohort 1) is a single-blind, randomized, placebo-controlled, 5-period crossover in which drug naïve T2DM subjects will receive escalating doses of GSK1292263 in each of 3 periods and placebo and open-label sitagliptin in the other 2 periods. The sequence will be randomized, but will maintain the low, medium and high dose order for GSK1292263.

Group Type: EXPERIMENTAL

GSK1292263

Intervention Type: DRUG

GSK1292263 is an immediate-release round, white, film-coated tablet provided in 3 strengths, 25mg, 75mg and 200mg being developed for the treatment of type 2 diabetes.
