• UACR ≥ 500 mg/g (56.5 mg/mmol) and ≤ 5000 mg/g (565 mg/mmol) (local or central laboratory value), or
• UPCR ≥ 700 mg/g (79 mg/mmol) and ≤ 7000 mg/g (790 mg/mmol) (local laboratory value only).

(b) eGFR 60-75 mL/min/1.73 m² (local or central laboratory value) AND:

• UACR ≥ 500 mg/g (56.5 mg/mmol) ) and ≤ 5000 mg/g (565 mg/mmol) (local or central laboratory value), or

• [obsolete]
• Participants with history of HTN and a SBP ≥ 130 mmHg (the most recent value within 4 weeks prior to screening or at the Screening Visit) and ≥ 120 mmHg at the Randomisation Visit.
• Stable and maximum tolerated dose of an ACEi or an ARB (not both) for at least 4 weeks prior to Screening Visit.
• Participants with:

• Serum or plasma potassium ≥ 3.0 and ≤ 4.8 mmol/L if eGFR ≥ 45 mL/min/1.73 m2 (local or central laboratory values)
• Serum or plasma potassium ≥ 3.0 and ≤ 4.5 mmol/L if eGFR \< 45 mL/min/1.73 m2 (local or central laboratory values)

Exclusion Criteria

• Known hyperkalaemia, defined as potassium of ≥ 5.5 mmol/L within 3 months at screening.
• Serum sodium \< 135 mmol/L (central or local laboratory values obtained within 4 weeks prior to screening or at the Screening Visit).

• Participants with T1DM will be excluded, except:

• For US only: patients with T1DM treated with SGLT2i for at least 4 months, without DKA during that period, and who have experience with ketone monitoring are eligible for inclusion.
• For Japan only: patients with T1DM treated with dapagliflozin 10 mg for at least 4 months, without DKA during the period of dapagliflozin treatment are eligible for inclusion.

6 New York Heart Association functional HF class IV at screening.

7 Stroke, transient ischaemic cerebral attack, valve implantation or valve replacement, carotid surgery, or carotid angioplasty, acute coronary syndrome, or hospitalisation for worsening heart failure within previous 3 months prior to randomisation.

8 Documented history of adrenal insufficiency.

9 Any dialysis (including for acute kidney injury) within 3 months prior to Screening Visit.

10 Any acute kidney injury within 3 months prior to the Screening Visit.

11 History of organ transplant or bone marrow transplant, or planned organ transplant within 6 months following randomisation (including kidney transplant).

12 Any clinical condition requiring systemic immunosuppression therapy other than maintenance therapy (stable for at least 3 months prior to Visit 1).
