Exclusion criteria

Exclusion criteria: 1. Systolic blood pressure > 180 mmHg, or diastolic BP > 110 mmHg at screening. 2. Known hyperkalaemia, defined as potassium of 5.5 mmol/L or more within 3 months prior to screening. 3. Serum sodium 10.5% (> 91 mmol/mol) (central or local laboratory values obtained within 3 months prior to screening or at the Screening Visit). 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).

Design outcomes

Primary

MeasureTime frame
To determine whether baxdrostat/dapagliflozin is superior to placebo/dapagliflozin in reducing the risk of the composite endpoint of 50% or more sustained decline in eGFR (estimated glomerular filtration rate) [Time Frame: Up to 41 months] - Time to the first occurrence of any of the components of the composite of 50% or more sustained decline in eGFR (estimated glomerular filtration rate). To determine whether baxdrostat/dapagliflozin is superior to placebo/dapagliflozin in reducing the risk of the composite endpoint of kidney failure [Time Frame: Up to 41 months] - Time to the first occurrence of any of the components of the composite of: - Onset of kidney failure: - Sustained eGFR < 15 mL/min/1.73 m2 or - Chronic dialysis treatment or - Receiving a kidney transplant or - Death with a renal primary cause (death due to kidney failure when dialysis is not given) To determine whether baxdrostat/dapagliflozin is superior to placebo/dapagliflozin in reducing the risk of the composite endpoint of CV (cardiovascular) death. [Time Frame: Up to 41 months] - Time to the first occurrence of any of the components of the composite of CV (cardiovascular) death
