Resumen

International, Multicenter, Double-Blind, Placebo-Controlled and Event-driven study to assess efficacy, safety and Tolerability of Baxdrostat in combination with Dapagliflozin on renal outcomes and cardiovascular mortality in participants with chronic kidney disease and high blood pressure

Descripción detallada

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 endpoint of ≥ 50% sustained decline in eGFR, kidney failure, HF events, or CV death in participants 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 (N = 845) ie, the PACD. All randomised participants including any participants who have prematurely discontinued study intervention will be scheduled for a SCV within 6 weeks of the PACD. This period can be extended by AstraZeneca. In case of premature discontinuation of blinded study intervention, participants will continue in the study and receive dapagliflozin 10 mg, unless the participant meets dapagliflozin specific discontinuation criteria. Baxdrostat/placebo should not be administered without dapagliflozin: baxdrostat/placebo should be interrupted if dapagliflozin is interrupted (baxdrostat/placebo may be resumed with dapagliflozin, if dapagliflozin is resumed), and should be permanently discontinued if dapagliflozin is permanently discontinued. 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.
