Effects of exenatide plus rosiglitazone on beta-cell function and insulin sensitivity in subjects with type 2 diabetes on metformin.

ABSTRACT:

Objective

Study the effects of exenatide (EXE) plus rosiglitazone (ROSI) on beta-cell function and insulin sensitivity using hyperglycemic and euglycemic insulin clamp techniques in participants with type 2 diabetes on metformin.

Research design and methods

In this 20-week, randomized, open-label, multicenter study, participants (mean age, 56 +/- 10 years; weight, 93 +/- 16 kg; A1C, 7.8 +/- 0.7%) continued their metformin regimen and received either EXE 10 microg b.i.d. (n = 45), ROSI 4 mg b.i.d. (n = 45), or EXE 10 microg b.i.d. + ROSI 4 mg b.i.d. (n = 47). Seventy-three participants underwent clamp procedures to quantitate insulin secretion and insulin sensitivity. RESULTS A1C declined in all groups (P < 0.05), but decreased most with EXE+ROSI (EXE+ROSI, -1.3 +/- 0.1%; ROS
