The purpose of this study is to assess the efficacy and safety of once-weekly dulaglutide compared to placebo in participants with type 2 diabetes who have inadequate glycemic control with sulfonylurea monotherapy.

Enrollment: 300 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Accept continued treatment with sulfonylurea therapy, throughout the trial, as required per protocol
• Men and nonpregnant women aged ≥18 years
• Stable weight (±5%) ≥3 months prior to screening
• Body Mass Index (BMI) ≤45 kilograms per square meter (kg/m^2)

Exclusion criteria

• Have been treated with ANY other antihyperglycemic medications (other than sulfonylurea) at the time of the first study visit or within 3 months prior to the first study visit
• Have used insulin therapy (outside of pregnancy) any time in the past 2 years, except for short-term treatment of acute conditions, and up to a maximum of 4 weeks; any insulin within 3 months prior to the first study visit is exclusionary
