Abstract
BACKGROUND: Exenatide therapy is effective in combination with metformin or sulfonylureas for treating type 2 diabetes. Thiazolidinediones (TZDs) also are commonly used, but the efficacy of exenatide with a TZD has not been reported. OBJECTIVE: To compare the effects of exenatide versus placebo on glycemic control. DESIGN: Placebo run-in, randomized, double-blind, placebo-controlled trial conducted from May 2004 to August 2005. SETTING: 49 sites in Canada, Spain, and the United States. PATIENTS: 233 (exenatide group, n = 121; placebo group, n = 112) patients with type 2 diabetes that was suboptimally controlled with TZD treatment (with or without metformin). Mean (+/-SE) baseline glycated hemoglobin A1c level was 7.9% +/- 0.1%. INTERVENTIONS: Subcutaneous abdominal injections of 10 microg of exenatide or placebo twice daily, added to a TZD (with or without metformin) for 16 weeks. MEASUREMENTS: The primary outcome was change from baseline in hemoglobin A1c level. Other outcomes were fasting serum glucose level, body weight, self-monitored blood glucose level, and any adverse events. RESULTS: Exenatide treatment reduced hemoglobin A(1c) level (mean difference, -0.98% [95% CI, -1.21% to -0.74%]), serum fasting glucose level (mean difference, -1.69 mmol/L [-30.5 mg/dL] [CI, -2.22 to -1.17 mmol/L {-40.0 to -21.1 mg/dL}]), and body weight (mean difference, -1.51 kg [CI, -2.15 to -0.88 kg]). Sixteen percent of patients in the exenatide group and 2% of patients in the placebo group discontinued treatment because of adverse events. In the exenatide group, 40% (n = 48) of patients experienced nausea (mostly mild [n = 21] or moderate [n = 19]), 13% experienced vomiting, and 11% experienced hypoglycemia. In the placebo group, 15% of patients experienced nausea, 1% experienced vomiting, and 7% experienced hypoglycemia. LIMITATIONS: Combinations with TZDs and sulfonylureas were not tested. Trial duration was relatively short. Only 71% and 86% of patients in the exenatide and placebo groups, respectively, completed the study. CONCLUSIONS: Exenatide therapy improved glycemic control, reduced body weight, and caused gastrointestinal symptoms more than placebo in patients with type 2 diabetes that was suboptimally controlled with TZD therapy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
