RESUMO
BACKGROUND: Evaluation of exenatide monotherapy in patients with type 2 diabetes may be of clinical interest based on improvements in glycemic control and weight that have been reported with the use of exenatide in combination with oral antidiabetic agents. OBJECTIVE: The aim of this study was to evaluate the efficacy and tolerability of exenatide monotherapy in patients with type 2 diabetes naive to antidiabetic agents and whose disease was inadequately controlled with diet and exercise alone. METHODS: This 24-week, double-blind, placebo-controlled, parallel-group study was conducted at 23 centers across the United States, Puerto Rico, Romania, Russia, and India. Patients aged >or=18 years with type 2 diabetes were randomly assigned to receive exenatide 5 microg, exenatide 10 microg, or placebo administered SC BID. Patients were instructed by investigators to maintain their individualized prestudy diet and exercise regimens throughout the study. Efficacy measures included: glycosylated hemoglobin (HbA(1c)); fasting serum glucose (FSG); 6-point self-monitored blood glucose; percentages of patients achieving HbA(1c) values
