A Phase III Study to Investigate the Efficacy and Safety of Baxdrostat in Combination With Dapagliflozin on CKD Progression in Participants With CKD and High Blood Pressure.

Summary

The purpose of this study is to measure the efficacy and safety of baxdrostat/dapagliflozin in participants ≥ 18 years of age with CKD and HTN. This study consists of a screening, a 4-week dapagliflozin run-in period for participants untreated with SGLT2i at baseline; a 24-month double-blind period in which participants will receive either baxdrostat/dapagliflozin or placebo/dapagliflozin; and approximately 12-week open-label period in which all participants will discontinue baxdrostat/placebo and receive dapagliflozin alone. Site visits will take place at 2-, 4-, 8-, and 16- weeks following randomisation. Thereafter visits will occur approximately every 4 months, until the 24-month visit at which time baxdrostat/placebo will be discontinued. Participants will continue open-label dapagliflozin for another 12-weeks (approximately), where reassessment of eGFR will occur for the primary efficacy endpoint. In the event of premature discontinuation of blinded study intervention, participants will continue in the study and receive open-label dapagliflozin monotherapy, unless the participant meets dapagliflozin specific discontinuation criteria, in which case all study interventions will be discontinued.
