Study Overview
Brief Summary
The main purpose of this study is to learn more about the safety and efficacy of investigational tirzepatide doses in participants with Type 2 diabetes and obesity that are already taking metformin. The study will last for about 89 weeks.
Detailed Description
The study will include a screening period of up to 5 weeks. The primary endpoint will be at Week 44 with a tirzepatide extension until week 80. A safety follow up will be performed approximately 4 weeks after end of treatment.
