1) Signed and dated written informed consent in accordance with International Council on Harmonisation - Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial
2) Male or female patients of legal adult age (according to local legislation) and aged greater than or equal to 18 years at time of consent
3) estimated Glomerular Filtration Rate (eGFR, Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula) greater than or equal to 30 and less than 90 mL/min/1.73 m2 at Visit 1 by central laboratory analysis
4) Urine Albumin Creatinine Ratio (UACR) greater than or equal to 200 and less than 5,000 mg/g in spot urine (midstream urine sample) by central laboratory analysis at Visit 1.1
5) If the patient is taking any of the following medications they should be on a stable dose for at least 4 weeks prior to visit 1 and until first randomisation prior to run-in with no planned change of the therapy during the trial: anti-hypertensives, Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), endothelin receptor antagonists, low dose systemic steroids (e.g. prednisolone less than or equal to 10 mg or equivalent)
6) Treatment with a clinically appropriate, stable dose of either Angiotensin-Converting Enzyme Inhibitor (ACEi) or Angiotensin Receptor Blocker (ARB) (but not both together), for greater than or equal to 4 weeks prior to visit 1 and until first randomisation with no planned change of the therapy during the trial
7) In the Investigators opinion, any kind of diagnosed chronic kidney disease (Diagnosis can be reached by standard clinical method, no biopsy required). Patients with diabetic kidney disease must have type 2 diabetes mellitus and their treatment (including GLP1 receptor agonist) should be unchanged or changes deemed minor (according to investigators judgement) within 4 weeks prior to Visit 1 and until first randomisation
8) Glycated Haemoglobin (HbA1c) less than 10.0% at Visit 1 measured by the central laboratory
9) Serum potassium less than or equal to 4.8 mmol/L at Visit 1 measured by the central laboratory
10) Seated Systolic Blood Pressure (SBP) greater than or equal to 110 and less than or equal to 160 mmHg and Diastolic Blood Pressure (DBP) greater than or equal to 65 and less than or equal to 110 mmHg at Visit 1 (mean values from three Blood Pressure (BP) measurements) and optimised anti-hypertensive treatment according to local standard of care and investigators judgement
11) Body Mass Index (BMI) greater than or equal to 18.5 and less than 50 kg/m2 at Visit 1
12) Women of child-bearing potential2 (WOCBP) must be ready and able to use highly effective methods of birth control. Such methods should be used throughout the trial. Men must be vasectomised or willing and able to use a condom if their partner is a WOCBP
Additional inclusion criteria to be assessed before second randomisation (start of Treatment Period):
13) Serum potassium less than or equal to 4.8 mmol/L measured by local or central laboratory within 7 days prior to randomisation to the Treatment Period
14) eGFR (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] formula) greater than or equal to 20 mL/min/1.73 m2 measured by local or central laboratory within 7 days prior to randomisation to the Treatment Period
1) Treatment with inhibitors of aldosterone mediated effects (e.g., mineralocorticoid receptor antagonists such as spironolactone), or intake of other potassium sparing diuretics (e.g., amiloride) within 7 days prior to first randomisation or planned during trial treatment phase
2) Treatment with other Renin Angiotensin Aldosterone System (RAAS) interventions (apart from either Angiotensin-Converting Enzyme Inhibitor (ACEi) or Angiotensin Receptor Blocker (ARB)) within 4 weeks prior to Visit 1 and throughout screening or planned during the trial. Patients who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial are also excluded
3) Type 1 diabetes mellitus, or history of other autoimmune causes of diabetes mellitus (e.g. Latent Autoimmune Diabetes (LADA))
4) Patients at increased risk of ketoacidosis in the opinion of the investigator
5) Currently receiving Sodium-glucose cotransporter (SGLT)-2 or SGLT-1/2 inhibitor or planned initiation during the trial
