Brief summary

Primary Objective: To demonstrate the non-inferiority of once weekly injection of efpeglenatide in comparison to once weekly injection of dulaglutide on glycated hemoglobin (HbA1c) change in participants with Type 2 diabetes mellitus (T2DM) inadequately controlled with metformin. Secondary Objectives: * To demonstrate the superiority of once weekly injection of efpeglenatide with once weekly injection of dulaglutide on glycemic control. * To demonstrate the superiority of once weekly injection of efpeglenatide with once weekly injection of dulaglutide on body weight. * To evaluate the safety of once weekly injection of efpeglenatide and once weekly injection of dulaglutide.

Participant flow

Recruitment details

The study was conducted at 45 active sites in 4 countries. A total of 1608 participants were screened between 26 September 2018 and 17 December 2019, out of which 700 were screen failures. Screen failures were mainly due to inclusion criteria not met.

Pre-assignment details

A total of 908 participants were randomized in 1:1:1 ratio to either efpeglenatide 4 milligram (mg), efpeglenatide 6 mg, or dulaglutide 1.5 mg treatment arms, stratified by screening glycated hemoglobin (HbA1c) values (less than \[\<\]8%, greater than or equal to \[\>=\]8 percent \[%\]) and by body mass index (BMI) (\<30 kg/m\^2 and \>=30 kg/m\^2) on Day 1.

Outcome results

Change From Baseline to Week 56 in HbA1c

Adjusted Least square (LS) means and Standard errors (SE) were obtained from analysis of covariance (ANCOVA) model to account for missing data. Missing values were imputed by baseline observation carried forward (BOCF)-like multiple imputation method.

Time frame: Baseline to Week 56

Population: Analysis was performed on modified intent-to-treat (mITT) population which included participants who completed study treatment; or who discontinued study treatment and completed/discontinued study before early termination; or who discontinued treatment before early termination and discontinued study due to early termination; or who discontinued treatment due to early termination within 30 days of target Week 56 visit.
