Primary Objective:
To demonstrate the superiority of once weekly injection of efpeglenatide in comparison to placebo in glycated hemoglobin (HbA1c) change in participants with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin alone or in combination with sulfonylurea (SU).
Secondary Objectives:
- To demonstrate the superiority of once weekly injection of efpeglenatide in comparison to placebo on glycemic control.
- To demonstrate the superiority of once weekly injection of efpeglenatide in comparison to placebo on body weight.
- To evaluate the safety of once weekly injection of efpeglenatide.

- Change From Baseline to Week 30 in HbA1c [ Time Frame: Baseline to Week 30 ]This analysis included all Week 30 assessment values available.
- Number of Participants With HbA1c <7.0% [ Time Frame: Week 30 ]Participants who had no available assessment for HbA1c <7% at Week 30 were considered as non-responders.
- Change From Baseline to Week 30 in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline to Week 30 ]This analysis included all Week 30 assessment values available.
- Change From Baseline to Week 30 in Body Weight [ Time Frame: Baseline to Week 30 ]This analysis included all Week 30 assessment values available.
- Number of Participants With At Least One Hypoglycemic Events (Documented Symptomatic Hypoglycemia <3.0 mmol/L [<54 mg/dL], Severe Hypoglycemia) [ Time Frame: Baseline up to Week 30 ]Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of <54 milligrams per deciliter (mg/dL) (<3.0 mmol/L). Severe hypoglycemia was an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions.
- Number of Hypoglycemic Events (Documented Symptomatic Hypoglycemia <3.0 mmol/L [<54 mg/dL] and Severe Hypoglycemia) Per Participant-Year [ Time Frame: Baseline up to Week 30 ]Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of <54 mg/dL (<3.0 mmol/L). Severe hypoglycemia was an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions.
