This study is looking at how a medicine called **orforglipron** helps people with **obesity** (who have a lot of extra body fat) or are **overweight** (weighing more than is healthy) and have **type 2 diabetes** (a condition where blood sugar levels are too high). The study compares orforglipron to a **placebo** (a fake treatment that looks like the real one) to see if it helps control blood sugar better.
**Key Points:**
- Participation lasts about 18 months.
- Participants must have a **BMI** (body mass index, which measures body fat) of 25 or more, and a **HbA1c** (a blood test for average blood sugar) between 7% and 10%.
- Cannot join if you have type 1 diabetes or certain heart problems.
