Inclusion criteria

•Participant must be greater than or equal to (>=)18 years of age at the time of signing the informed consent.

•Participants with T2DM.

•Diabetes diagnosed at least 1 year before screening.

•Participants on metformin alone or in combination with SU, for at least 3 months prior to screening.

•Glycated hemoglobin between 7.0% and 10.0% (inclusive) measured by the central laboratory at screening.

Exclusion criteria

•History of severe hypoglycemia requiring emergency room admission or hospitalization within 3 months prior to screening.

•Retinopathy or maculopathy with one of the following treatments, either recent (within 3 months prior to screening) or planned: intravitreal injections or laser or vitrectomy surgery.

•Clinically relevant history of gastrointestinal disease associated with prolonged nausea and vomiting, including (but not limited to) gastroparesis, unstable and not controlled gastroesophageal reflux disease requiring medical treatment within 6 months prior to screening or history of surgery affecting gastric emptying.

•History of pancreatitis (unless pancreatitis was related to gallstones and cholecystectomy has been performed), pancreatitis during previous treatment with incretin therapies, chronic pancreatitis, pancreatectomy.

•Personal or family history of medullary thyroid cancer (MTC) or genetic conditions that predispose to MTC (e.g., multiple endocrine neoplasia syndromes).

•Body weight change of >=5 kilograms within the last 3 months prior to screening.

•Systolic blood pressure greater than (>)180 millimeters of mercury (mmHg) and/or diastolic blood pressure >100 mmHg at randomization.

•Severe renal disease as defined by estimated glomerular filtration rate (eGFR) of <30 milliliters per minute per 1.73 square meter.

•Laboratory findings at the screening visit:

–Alanine aminotransferase or aspartate aminotransferase >3*upper limit of the normal (ULN) or total bilirubin >1.5*ULN (except in case of documented Gilbert's syndrome);

–Amylase and/or lipase: >3*ULN laboratory range;

–Calcitonin >=5.9 picomoles per liter (20 picograms per milliliter).

•Gastric surgery or other gastric procedures intended for weight loss within 2 years prior to screening, or planned during study period.

•Pregnant (confirmed by serum pregnancy test at screening) or breast-feeding women.

•Women of childbearing potential not willing to use highly effective method(s) of birth control or who are unwilling to be tested for pregnancy during the study period and for at least 5 weeks after the last dose of study intervention.
