Study Endpoints
Primary Endpoints
Change From Baseline in Hemoglobin A1c (HbA1c) (Pooled Doses of Tirzepatide 5 mg and 10 mg)
Baseline, Week 30

HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. Least Squares (LS) mean was determined by ANCOVA model for endpoint measures: Variable = Baseline + Baseline Antihyperglycemic medication + Baseline Age group + Treatment (Type III sum of squares)

Secondary Endpoints
Change From Baseline in HbA1c (Individual Doses)
Baseline, Week 30
Percentage of Participants Who Achieve ≤6.5% of HbA1c
Week 30
Change From Baseline in Body Mass Index (BMI) Standard Deviation Score (Age and Sex-matched)
