Study Details

Study Description

Brief 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 and placebo affect the body's ability to respond to blood sugar levels after a meal. The study will last up to 38 weeks, including a 28-week treatment period.

    Outcome Measures

    Primary Outcome Measures

    1. Change from Baseline in Total Clamp Disposition Index (cDI) [Baseline, Week 28]

      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 (ISR0-120min) 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.

    Secondary Outcome Measures

    1. Change from Baseline in Fasting Glucose [Baseline, Week 28]

      Measured prior to standardized mixed-meal tolerance tests (sMMTT)

    2. Change from Baseline in Postmeal Glucose [Baseline, Week 28]

      Measured during sMMTT

    3. Change from Baseline in Hemoglobin A1c (HbA1c) [Baseline, Week 28]

      Change from Baseline in HbA1c

    4. Total Insulin Secretion Rate During the 120-Minute Hyperglycemic Clamp (ISR0-120min) [Baseline and Week 28]

      ISR0-120 will be determined from C-peptide concentrations using the deconvolution technique

    5. Change from Baseline in Hyperinsulinemic Euglycemic Clamp M-value [Baseline, Week 28]

      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

    6. Glucagon Concentration at Fasting [Baseline and Week 28]

      Measured prior to sMMTT

    7. Glucagon Concentration at Postmeal [Baseline and Week 28]

      Incremental AUC from time zero to 240 minutes after start of the meal [AUC0-240min]) during sMMTT

    8. Change from Baseline in Food Intake During Ad Libitum Meal [Baseline, Week 28]

      Ad libitum meal served buffet-style. Food intake will be recorded during a 45 minute period. The total amount of calories as well as the caloric breakdown (carbohydrates, protein, and fats) will be calculated from the respective nutritional information of the food items.
