A Study of Tirzepatide in Participants With Type 2 Diabetes Mellitus (T2DM)
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
- 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
- Change from Baseline in Fasting Glucose [Baseline, Week 28]
Measured prior to standardized mixed-meal tolerance tests (sMMTT)
- Change from Baseline in Postmeal Glucose [Baseline, Week 28]
Measured during sMMTT
- Change from Baseline in Hemoglobin A1c (HbA1c) [Baseline, Week 28]
Change from Baseline in HbA1c
- 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
- 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
- Glucagon Concentration at Fasting [Baseline and Week 28]
Measured prior to sMMTT
- 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
- 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.
