study to evaluate the effect of balcinrenone/dapagliflozin in patients with heart failure and impaired kidney function

Conditions: Heart Failure and Impaired Kidney Function

Summary: this is a phase iii, international, multi-centre, randomised, double-blind, parallel-group, double-dummy, active-controlled, event-driven study in patients with chronic hf and impaired kidney function who had a recent hf event. the aim is to evaluate the effect of balcinrenone/dapagliflozin vs dapagliflozin, given once daily on top of other classes of soc, on cv death and hf events.

the purpose of this study is to investigate the effect of balcinrenone/dapagliflozin compared with dapagliflozin, on the risk of cv death, hf event with and without hospitalisation, in patients with chronic hf, impaired kidney function, and who have had a recent hf event. eligible patients will randomly be assigned with a 1:1:1 ratio to receive once daily administration of one capsule and one tablet of one of the following treatments: 1. balcinrenone/dapagliflozin 15 mg/10 mg capsule and matching placebo for dapagliflozin 10 mg tablet 2. balcinrenone/dapagliflozin 40 mg/10 mg capsule and matching placebo for dapagliflozin 10 mg tablet 3. dapagliflozin 10 mg tablet and matching placebo for balcinrenone/dapagliflozin capsule the study is event driven, and the average study duration for a participant is estimated to be 22 months including screening period, 20 months blinded treatment period and a one-month follow-up period on open-label dapagliflozin. the study will be conducted at approximately 700 sites in approximately 40 countries globally.
