9. Willing and able to give written informed consent for study participation and provide consent for access to medical data according to appropriate local data protection legislation, allowing authorization to access medical records and describe events captured in the endpoints

Exclusion Criteria:

1. Type 1 diabetes mellitus (juvenile onset). If a history of diabetic ketoacidosis exists, a C-peptide level must confirm type 2 diabetes;
2. Known non-diabetic renal disease (e.g., polycystic kidney disease, focal segmental glomerulosclerosis) \[nephrosclerosis superimposed on diabetic kidney disease is acceptable\];
3. Ongoing clinical evidence suggesting non-diabetic renal disease other than nephrosclerosis;
4. History of a renal transplant or a planned transplant from a living donor during the study;
5. Albumin to creatinine ratio (ACR) greater than 3500 mg/g (395.5 mg/mmol);
6. Hemoglobin A1c level \> 11.0% (97 mmol/mol) during screening;
7. Acute dialysis or acute kidney injury within 12 weeks prior to screening or during screening;
8. Clinical signs and/or symptoms of uremia and expected need for renal replacement therapy within 12 weeks following randomization, as assessed by the investigator;
9. Recently active cardiovascular disease defined as: a. Unstable angina pectoris within 12 weeks before study randomization; b. Myocardial infarction, coronary artery bypass graft surgery, or percutaneous transluminal coronary angioplasty/stent within 12 weeks before study randomization; c. Cerebrovascular accident, including transient ischemic attack within 12 weeks before study randomization; d. Current diagnosis of Class III or IV New York Heart Association (NYHA) congestive heart failure;
10. Clinical diagnosis of severe obstructive valvular heart disease or severe obstructive hypertrophic cardiomyopathy;
11. Atrioventricular block, 2o or 3o, not successfully treated with a pacemaker;
12. DAdministration of a contrast agent that may induce nephropathy within 30 days prior to study randomization or planned during the study;
