E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the dose response and efficacy of GW823093 (2.5mg, 7.5mg, 15mg, 30mg and 45mg), versus placebo on the change in HbA1c after 12 weeks of dosing in subjects with T2DM. |
|
E.2.2 | Secondary objectives of the trial |
• To investigate the safety and tolerability of a range of doses of GW823093 versus placebo over 12 weeks of dosing in subjects with T2DM. • To evaluate the effect of a range of doses of GW823093, versus placebo, on glycemic parameters (HbA1c, fasting plasma glucose (FPG), fasting fructosamine), fasting insulin and serum lipid profile during 12 weeks of dosing in subjects with T2DM. • To characterize the pharmacokinetics of GW823093 in type 2 diabetic subjects after chronic administration using a combined sparse and serial sampling scheme, and to investigate pharmacokinetic/pharmacodynamic relationships (e.g. safety and efficacy endpoints). • To evaluate the effect of a range of doses of GW823093 on DPP-IV inhibition as part of population PK assessment |
