Efficacy of Exenatide Plus Pioglitazone Vs Basal/Bolus Insulin in T2DM Patients With Very High HbA1c

Objective: To examine the efficacy and safety of combination therapy with exenatide plus pioglitazone vs basal/bolus insulin in patients with poorly controlled type 2 diabetes mellitus (T2DM) with very high hemoglobin A1c (HbA1c) (>10%) receiving sulfonylurea plus metformin and with a long duration of disease. Design and Participants: Participants (n = 101) in the Qatar Study with very poor glycemic control (HbA1c >10%) and a long duration of diabetes (10.9 years) receiving maximum/near-maximum doses of sulfonylurea plus metformin were randomly assigned to receive pioglitazone plus weekly exenatide (combination therapy), or basal plus prandial insulin (insulin therapy), to maintain HbA1c 10%).
