Experimental Baxdrostat/dapagliflozin |
Participants randomised to the baxdrostat/dapagliflozin arm will initially receive a lower dose of baxdrostat and standard dose dapagliflozin. For participants that meet the up-titration criteria, baxdrostat may be up-titrated to higher dose. |

|
Placebo Comparator Placebo/dapagliflozin |
Patients will receive one dose of dapagliflozin comparator in combination with matching placebo daily. |

Detailed Description
The purpose of this study is to investigate the efficacy, safety, and tolerability of baxdrostat in combination with dapagliflozin, compared with placebo and dapagliflozin, in reducing the risk of the composite of >= 50% sustained decline in eGFR, kidney failure, or CV death, in individuals with CKD and HTN. This study consists of a 4-week dapagliflozin Run-in Period for participants untreated with SGLT2i at screening, and a double-blinded period where participants will receive either baxdrostat/dapagliflozin or placebo/dapagliflozin. Site visits will take place at 2-, 4-, 8-, 16-, 34, and 52-weeks following randomisation. Thereafter visits will occur approximately every 4 months. The study closure procedures will be initiated when the predetermined number of primary endpoint events is predicted to have occurred ie, the PACD. All randomised participants including any participants who have prematurely discontinued study intervention will be scheduled for a SCV within a few weeks of the PACD. This period can be extended by the Sponsor. In case of premature discontinuation of blinded study intervention, participants will continue in the study and receive dapagliflozin, unless the participant meets dapagliflozin specific discontinuation criteria. If study intervention is temporarily or permanently discontinued, the participant should remain in the study, and it is important that the scheduled study visits (including the PTDV for participants with permanent discontinuation of study intervention) and data collection continue according to the study protocol until the SCV.
