Inclusion criteria

Diagnosis of Type 2 Diabetes Mellitus (T2DM) at least 3 months prior to Screening
On a stable treatment regimen at least 3 months prior to Screening of (1) diet and exercise, or (2) metformin monotherapy (at a dose of at least 1,000 milligram (mg) per day)
Blood pressure between 90 and 140 millimeter of mercury (mmHg) systolic, inclusive, and between 60 and 100 mmHg diastolic, inclusive at Screening (sitting) and Day -2 (supine). If blood pressure is out of range, up to 2 repeated assessments are permitted
HbA1c greater than or equal to 6.5% and less than 8.5% at Screening
Females of non-childbearing potential

Exclusion criteria

History of, or currently active, significant illness or medical disorders, including cardiovascular disease (including cardiac arrhythmias, myocardial infarction, stroke, peripheral vascular disease), hematological disease (example, von Willebrand's disease or other bleeding disorders), respiratory disease, hepatic or gastrointestinal disease, neurological or psychiatric disease, ophthalmologic disorders, neoplastic disease, skin disorder, renal disorder, or any other illness that the Principal Investigator (PI) considers should exclude the participant or that could interfere with the interpretation of the study results
Previous surgical treatment for obesity (example, gastric bypass, gastric banding)
History of diabetic neuropathy with signs of gastroparesis and/or known proliferative retinopathy or maculopathy
History or current diagnosis of acute or chronic pancreatitis
History of an invasive cardiovascular surgical procedure including, but not limited to, coronary artery bypass graft (CABG), or percutaneous coronary intervention (PCI)
