Exclusion Criteria
  • Have type 1 diabetes (T1D).
  • Have used any glucose-lowering medication other than metformin within 3 months prior to study entry or during screening/lead-in period or have used any glucagon-like peptide-1 receptor agonists (GLP-1 RAs) at any time in the past.
  • Have had any of the following cardiovascular conditions: acute myocardial infarction (MI), New York Heart Association Class III or Class IV heart failure, or cerebrovascular accident (stroke).
  • Have acute or chronic hepatitis, signs and symptoms of any other liver disease other than nonalcoholic fatty liver disease (NAFLD), or alanine aminotransferase (ALT) level >2.5 times the upper limit of the reference range, as determined by the central laboratory at study entry; participants with NAFLD are eligible for participation in this trial.

Primary Outcome Measures
NameTimeMethod
Change From Baseline to Week 26 in Hemoglobin A1c (HbA1c) Bayesian Dose ResponseBaseline, Week 26

HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time.This was a Bayesian dose response analysis of HbA1c (%) change from baseline. At baseline: Mean (SD = Standard Deviation) of baseline HbA1c (%). After baseline: Posterior Mean (SD = Posterior Standard Deviation) of HbA1c (%) change from baseline.

The Least Squares Mean is Posterior mean.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline to Week 12 in Hemoglobin A1c (HbA1c) Bayesian Dose ResponseBaseline, Week 12

HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time. This was a Bayesian dose response analysis of HbA1c (%) change from baseline. At baseline: Mean (SD = Standard Deviation) of baseline HbA1c (%). After baseline: Posterior Mean (SD = Posterior Standard Deviation) of HbA1c (%) change from baseline.

The Least Squares Mean is Posterior mean.

Change From Baseline to Week 26 in HbA1cBaseline, Week 26

HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time. The Least Squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included the independent variables: Baseline + Baseline BMI Group + Baseline Metformin Flag + Treatment + Time + Treatment\*Time.

Change From Baseline in Body WeightBaseline, Week 26

Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with independent variables: Baseline + Baseline HbA1C Group + Baseline BMI Group + Baseline Metformin Flag + Treatment + Time + Treatment\*Time.

Percentage of Participants With 10% or Greater Body Weight Loss From BaselineWeek 26

Percentage of participants with 10% or greater body weight loss from baseline LOCF analyses using Logistic regression model with Baseline value + Baseline HbA1C Group + Baseline BMI Group + Baseline Metformin + Treatment as factors.

Change From Baseline in Total CholesterolBaseline, Week 26

LS means were calculated using MMRM model with independent variables: Baseline, Baseline HbA1C Group, Baseline BMI Group, Baseline Metformin Flag, Treatment, Time, Treatment\*Time.

Change From Baseline in TriglyceridesBaseline, Week 26

LS means were calculated using MMRM model with independent variables: Baseline, Baseline HbA1C Group, Baseline BMI Group, Baseline Metformin Flag, Treatment, Time, Treatment\*Time.

Change From Baseline in Waist CircumferenceBaseline, Week 26

LS means were calculated using MMRM model with independent variables: Baseline, Baseline HbA1C Group, Baseline BMI Group, Baseline Metformin Flag, Treatment, Time, Treatment\*Time.

Change From Baseline to Week 12 in HbA1cBaseline, Week 12

HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time. The Least Squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included the independent variables: Baseline + Baseline BMI Group + Baseline Metformin Flag + Treatment + Time + Treatment\*Time.

Percentage of Participants With 5% or Greater Body Weight Loss From BaselineWeek 26

Percentage of participants with 5% or greater body weight loss from baseline last observation carried forward (LOCF) analyses using Logistic regression model with Baseline value + Baseline HbA1C Group + Baseline BMI Group + Baseline Metformin + Treatment as factors.

Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C)Baseline, Week 26

LS means were calculated using MMRM model with independent variables: Baseline, Baseline HbA1C Group, Baseline BMI Group, Baseline Metformin Flag, Treatment, Time, Treatment\*Time.

Percentage of Participants Reaching the HbA1c Target of ≤6.5%Week 26

Percentage of participants with HbA1c ≤6.5% at Week 26 using a logistic regression model for endpoint used last observation carried forward (LOCF) method including baseline value, baseline BMI Group, baseline Metformin and treatment as factors.

Percentage of Participants Reaching the HbA1c Target of <7.0%Week 26

Percentage of participants with HbA1c \<7.0% at Week 26 using a logistic regression model for endpoint used last observation carried forward (LOCF) method including baseline value, baseline BMI Group, baseline Metformin and treatment as factors.

Number of Participants With Anti-Drug Antibodies.

Pharmacokinetics (PK): Model Predicted Concentration at Steady State (Css) of TirzepatidePredose: Week 1,8,12 and 26; Postdose: Week 1,2,4 and 12

Pharmacokinetics (PK): Model Predicted Concentration at Steady State (Css) of Tirzepatide

Change From Baseline in Fasting Blood GlucoseBaseline, Week 26

Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with covariates: Baseline + Baseline HbA1C Group + Baseline BMI Group + Baseline Metformin Flag + Treatment + Time + Treatment\*Time.

Change From Baseline in High-Density Lipoprotein Cholesterol (HDL-C)Baseline, Week 26

LS means were calculated using MMRM model with independent variables: Baseline, Baseline HbA1C Group, Baseline BMI Group, Baseline Metformin Flag,Treatment, time, treatment\*time.
