The purpose of this study is to learn more about the safety and efficacy of tirzepatide compared to placebo in children or teenagers with type 2 diabetes taking metformin, or basal insulin, or both.
The overall study will last about 60 weeks with up to 14 clinic visits and 6 phone visits. Clinic visits will include blood sample collection, physical exam and questionnaire.

Arm | Intervention/treatment |
---|---|
Experimental: Tirzepatide Dose 1
Double-Blind: Participants receive Tirzepatide by weekly subcutaneous (SC) injection starting with a low dose then increase to a higher dose every four weeks until maintenance dose level 1 is reached. Open-Label: Participants will continue to receive Tirzepatide at the last dose level |
Drug: Tirzepatide Dose 1
Administered SC |
Experimental: Tirzepatide Dose 2
Double-Blind: Participants receive Tirzepatide by weekly SC injection starting with a low dose then increase to a higher dose every four weeks until maintenance dose level 2 is reached. Open-Label: Participants will continue to receive Tirzepatide at the last dose level |
Drug: Tirzepatide Dose 2
Administered SC |
Placebo Comparator: Placebo
Double-Blind: Participants receive placebo during the 30-week double-blind period. Open-Label: Participants will switch to Tirzepatide by weekly SC injection starting with a low dose then increase to a higher dose every four weeks until maintenance dose level 1 is reached. |

- Change from Baseline in HbA1c (Individual Doses) [ Time Frame: Baseline, Week 30 ]
- Change From Baseline in Body Mass Index (BMI) Standard Deviation Score (age and sex-matched) [ Time Frame: Baseline, Week 30 ]
- Change From Baseline in Fasting Serum Glucose (FSG) [ Time Frame: Baseline, Week 30 ]
- Percentage of Participants Who Achieve ≤6.5% of HbA1c [ Time Frame: Week 30 ]
- Percentage of Participants Who Achieve <7.0% of HbA1c [ Time Frame: Week 30 ]
- Percentage of Participants Who Achieve <5.7% of HbA1c [ Time Frame: Week 30 ]
- Change From Baseline for Serum Lipid Levels [ Time Frame: Baseline, Week 30 ]
- Change From Baseline in Height Standard Deviation Score (SDS) [ Time Frame: Baseline, Week 30 ]
- Change From Baseline in Weight SDS [ Time Frame: Baseline, Week 30 ]
- Pharmacokinetics (PK): Area Under the Concentration Curve (AUC), Steady State (ss) of Tirzepatide [ Time Frame: Baseline to Week 30 ]
- Change From Baseline in PedsQL Generic Core Scale [ Time Frame: Baseline, Week 52 ]The PedsQL Generic Core Scale has 23 items that measure the core dimensions of health: physical, emotional, and social and school functioning. Scores range from 0 to 100. Higher scores indicate better health related quality of life.
- Change From Baseline PedsQL (3.2) Diabetic Module [ Time Frame: Baseline, Week 52 ]The PedsQL 3.2 Diabetes Module has 33 items for ages 13 to 45 years, and 32 items (1 less item for the Worry Scale) for ages 2 to 12 years. The 5 dimensions consist of diabetes symptoms, treatment barriers, treatment adherence, worry and communication. Scores range from 0 to 100. Higher scores indicate less problems.
