Design outcomes

Primary

MeasureTime frame
We are adopting two primary endpoints. The change from baseline to end of treatment (i.e., after 6 months of treatment) in both fasting blood glucose and glycated hemoglobin levels, HbA1C. Subjects who, after 16 weeks of treatment, achieve (yes/no) HbA1c <7% (53 mmol/mol) and less than 120 mg/dl fasting blood glucose levels.

Secondary

MeasureTime frame
- Changes in incretin levels; glucagon-like peptide (GLP-1), and glucose insulinotropic polypeptide (GIP) levels from baseline compared to levels at the end of the intervention. - Changes in glucagon, C-peptide, and fasting insulin levels from baseline compared to levels at the end of the intervention. - Changes in beta-cell function (homeostatic model assessment index of beta-cell function (HOMA-B) from baseline compared to levels at the end of the intervention. - Changes in body mass index (BMI), blood pressure, mid-arm circumference, and polyuria.
