Study summary

This is a study for participants with type 2 diabetes mellitus. The main purpose of this study is to learn more about how tirzepatide, semaglutide and placebo affect the body's ability to respond to blood sugar levels after a meal. The study will last up to 40 weeks, including a 28-week treatment period.

What researchers measure

Primary outcomes

  1. Change From Baseline in Total Clamp Disposition Index (cDI)

    cDI is defined as the product of the M-value derived from the hyperinsulinemic euglycemic clamp over the last 30 minutes and total insulin secretion (ISR AUC0-120min) derived from the insulin secretion rate based on C-peptide using the using the deconvolution technique divided by the total glucose AUC0-120min from the hyperglycemic clamp portion of the study. Least squares (LS) mean was determined by analysis of covariance (ANCOVA) model for endpoint measures: log(Actual Measurement/Baseline) = log(Baseline) + Treatment (Type III sum of squares).

    Time frame: Baseline, Week 28

Secondary outcomes

  1. Change From Baseline in Fasting Glucose

    Fasting glucose is a test to determine sugar levels in blood sample after an overnight fast. Fasting glucose was measured prior to standardized mixed-meal tolerance tests (sMMTT). LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Treatment (Type III sum of squares).

    Time frame: Baseline, Week 28

  2. Change From Baseline in Postmeal Glucose

    Total AUC from time zero to 240 minutes after start of the meal \[AUC0-240min\]) during sMMTT was evaluated. LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Treatment (Type III sum of squares) and ANOVA model for baseline measures: Variable = Treatment (Type III sum of squares).

    Time frame: Baseline, Week 28

  3. Change From Baseline in Hemoglobin A1c (HbA1c)

    HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. LS mean was determined by mixed model repeated measures; (MMRM) model for post-baseline measures: Variable = Baseline + Treatment + Time + Treatment\*Time (Type III sum of squares).

    Time frame: Baseline, Week 28

  4. Change From Baseline in Total Insulin Secretion Rate During the 120-Minute Hyperglycemic Clamp (ISR0-120min)

    Total Insulin Secretion Rate During the 120-Minute Hyperglycemic Clamp (ISR0-120min) will be determined from C-peptide concentrations using the deconvolution technique. LS mean was determined by ANCOVA model for endpoint measures: log(Actual Measurement/Baseline) = log(Baseline) + Treatment (Type III sum of squares).

    Time frame: Baseline and Week 28

  5. Change From Baseline in Hyperinsulinemic Euglycemic Clamp M-value

    Hyperinsulinemic euglycemic clamp M-value is calculated from glucose infusion rate (GIR) over the last 30 minutes, corresponding to steady-state (+150 to +180 minutes), corrected for urine loss and space. LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Treatment (Type III sum of squares).

    Time frame: Baseline, Week 28

  6. Change From Baseline in Glucagon Concentration at Fasting

    Glucagon concentration was measured prior to sMMTT. LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Treatment (Type III sum of squares).

    Time frame: Baseline and Week 28

  7. Change From Baseline in Glucagon Concentration at Postmeal

    Total AUC from time zero to 240 minutes after start of the meal \[AUC0-240min\]) during sMMTT. LS mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Treatment (Type III sum of squares).

    Time frame: Baseline and Week 28

  8. Change From Baseline in Food Intake During Ad Libitum Meal

    Ad libitum meal served buffet-style. Food intake was recorded during a 45 minute period. The sum of the caloric breakdown (carbohydrates, protein, and fats) was calculated from the respective nutritional information of the food items. LS mean was determined by MMRM model for post-baseline measures: Variable = Baseline + Treatment + Time + Treatment\*Time (Type III sum of squares).
