To Investigate the Safety, Tolerability and Pharmacodynamics of GSK2890457 in Healthy Volunteers and Subjects With Type 2 Diabetes

Overview[ - collapse ][ - ]

Purpose This study is the first administration of GSK2890457 in humans. The study will be conducted in 3 parts: - Part A (conducted at a single investigative site) will determine the safety and tolerability of GSK2890457 alone in healthy subjects during six weeks of dosing, as well as evaluating the potential for a pharmacokinetic interaction with metformin. Part A consists of Screening, Treatment (6 weeks) and Follow-up periods. - Part B (conducted at multiple sites) will determine safety, tolerability, and pharmacodynamics (PD) in subjects with Type 2 diabetes (T2D) when co-dosed for six weeks with liraglutide (Victoza). Part B consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods. - Part C (conducted at multiple sites) will determine safety, tolerability, and PD in subjects with T2D when co-dosed for 6 weeks with metformin. Part C consists of Screening, Run-in (1 week), Stabilization (12 weeks), Treatment (6 weeks) and Follow-up periods.

  • Area under the curve weighted mean AUCs (0 to 4 hours) for glucose and insulin [Time Frame: Parts B and Part C - Day - 1 and Day 42] [Designated as safety issue: No]On Days -1 and 42 in subjects with T2D (Parts B and C).
  • Change form Baseline in HbA1c [Time Frame: Parts B & C - Day -1 and Day 42] [Designated as safety issue: No]Change from baseline HbA1c will be analyzed using an ANCOVA model. Differences in least squares means between the GSK2890457 treated groups and placebo will be reported
Current Secondary Outcome Measures
