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 basal insulin alone or in combination with oral antidiabetic drugs (OADs).
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.

Placebo Comparator: Placebo
Participants received placebo (matched to efpeglenatide) subcutaneous (SC) injection once weekly up to Week 56 on top of basal insulin alone or in combination with oral antidiabetic drugs (OADs).
|
Drug: Placebo
Pharmaceutical form: solution for injection Route of administration: subcutaneous Drug: Background therapy Lantus (Insulin Glargine), SC, once daily; OADs, administered as per investigator prescription and in accordance with local labeling. |
Experimental: Efpeglenatide 2 mg
Participants received Efpeglenatide 2 milligrams (mg) SC injection once weekly up to Week 56 on top of basal insulin alone or in combination with OADs.

Drug: Efpeglenatide SAR439977
Pharmaceutical form: solution for injection Route of administration: subcutaneous Drug: Background therapy Lantus (Insulin Glargine), SC, once daily; OADs, administered as per investigator prescription and in accordance with local labeling. |
Experimental: Efpeglenatide 4 mg
Participants received Efpeglenatide 4 mg SC injection once weekly up to Week 56 on top of basal insulin alone or in combination with OADs. Participants initiated dosing at 2 mg once weekly up to Week 1; which was up titrated to 4 mg and maintained at the 4 mg dose through-out the treatment duration up to Week 56.

Experimental: Efpeglenatide 6 mg
Participants received Efpeglenatide 6 mg SC injection once weekly up to Week 56 on top of basal insulin alone or in combination with OADs. Participants initiated dosing at 2 mg once weekly up to Week 1; which was up titrated to 4 mg until Week 4 and later up-titrated to 6 mg and maintained at the 6 mg dose through-out the treatment duration up to Week 56.

- Change From Baseline to Week 30 in HbA1c [ Time Frame: Baseline to Week 30 ]
- Number of Participants With HbA1c <7.0% at Week 30 [ Time Frame: Week 30 ]Participants who had no available assessment for HbA1c at Week 30 were considered as non-responders.
- Change From Baseline to Week 56 in HbA1c [ Time Frame: Baseline to Week 56 ]This analysis included Week 56 assessment performed per protocol as well as premature end of treatment/study visit recorded as Week 56 due to early termination.
- Change From Baseline to Week 30 in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline to Week 30 ]
- Change From Baseline to Week 30 and Week 56 in Body Weight [ Time Frame: Baseline to Week 30 and Week 56 ]This analysis included Week 56 assessment performed per protocol as well as premature end of treatment/study visit recorded as Week 56 due to early termination.
- Number of Participants With At Least One Hypoglycemic Events (Documented Symptomatic Hypoglycemia <3.0 mmol/L [<54 mg/dL], and Severe Hypoglycemia) [ Time Frame: Baseline up to Week 56 ]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.
- 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 56 ]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.
