Inclusion Criteria:

• Subject must have an estimated glomerular filtration rate (eGFR) ) >=25 and <75 ml/min/1.73m2.
• Subject must have a documented diagnosis of T2DM and received anti-diabetic medication (oral and/or parenteral) for at least 1 year prior to screening
• Subject's glycated hemoglobin (HbA1c) level is < 11.0% (<97 mmol/mol) at screening.
• Subject is on a stable therapy with an angiotensin-converting-enzyme (ACE) inhibitor or angiotensin receptor blockers (ARB) for at least 3 months prior to screening.
• Subject who receives anti-hypertensive treatment, non-insulin anti-diabetic agents and/or vitamin D receptor activators at screening needs to be on stable therapy for at least 3 months prior to screening. Subjects on insulin therapy may have the insulin type/dose/schedule adjusted even during the 3 months prior to screening.
• If the subject has been subjected to specific dietary interventions then this has to be stable over the past 3 months prior to screening visit.
• Subject's UACR is ≥ 200 and ≤ 3000 mg/g in a first morning void (FMV) sample at screening AND the geometric mean UACR of all FMV samples at visit 4 and at visit 5 is ≥ 200 and ≤ 3000 mg/g AND the UACR in at least 3 FMV samples at visit 4 and visit 5 is ≥ 200 mg/g.

Exclusion Criteria:

• Subject is on, or previously received, renal replacement therapy (e.g. dialysis or kidney transplantation).
• Subject has obstructive uropathy or other causes of renal impairment not related to parenchymal renal disorder and/or disease of the kidney; or subject currently has or has had in the past renal disease secondary to malignancy.
• Subject's renal impairment and/or albuminuria is considered to be of other origin than Diabetic Kidney Disease.
• Subject has known (auto-) immune disorder and/or received immunosuppression for more than 2 weeks, cumulatively, within 12 weeks prior to screening or anticipated need for immuno-suppressive therapy during the study.
• Subject has active urinary tract infection which requires treatment or clinically significant infection at the time of screening or randomization
• Subject is diagnosed with type 1 diabetes mellitus or diabetes mellitus with unclear etiology.
• Subject has a sitting systolic blood pressure (SBP) <90 or >160 mmHg and/or a diastolic blood pressure (DBP) >90 mmHg at screening.
