Efficacy, Safety and Tolerability of AZD9977 and Dapagliflozin in Participants With Heart Failure and Chronic Kidney Disease — MIRACLE  

Heart Failure Clinical Trial

Official title: A Phase 2b, Randomised, Double-Blind, Active Controlled, Multi Centre Study to Evaluate the Efficacy, Safety and Tolerability of Oral AZD9977 and Dapagliflozin Treatment in Patients With Heart Failure and Chronic Kidney Disease

Status Completed

Clinical Trial Summary

The purpose of the study is to evaluate the efficacy and safety of AZD9977 in combination with dapagliflozin compared with dapagliflozin alone and to assess the dose-response relationship, dapagliflozin alone and 3 doses of AZD9977 combined with dapagliflozin on urinary albumin to creatinine ratio (UACR). The study will be conducted in participants with heart failure (HF) with left ventricular ejection fraction (LVEF [below 60%]) and chronic kidney disease (CKD) with estimated glomerular filtration rate (eGFR [between ≥ 20 and ≤ 60 mL/min/1.73 m^2, with at least 20% of participants with eGFR ≥ 20 to <30 mL/min/1.73^2 and a maximum of 35% of participants with eGFR ≥ 45 mL/min/1.73 m^2]).

Clinical Trial Description

After screening, eligible participants will undergo a run-in period where all participants receive dapagliflozin for up to 7 weeks depending on pre-study use of SGLT2i or not. At the end of the run-in period, eligible participants will be randomly assigned with a 1:1:1:1 ratio to receive once daily administration of one of the following 4 study treatments group for 12 weeks. To ensure blinding, the study treatment will be administered in the form of 3 oral capsules of AZD9977 or placebo and 1 oral tablet or dapagliflozin. 1. AZD9977 Dose A + dapagliflozin 10 mg 2. AZD9977 Dose B + dapagliflozin 10 mg 3. AZD9977 Dose C + dapagliflozin 10 mg 4. Dapagliflozin 10 mg Participants will be randomized to one of the above treatment group, according to type 2 diabetes mellitus [T2DM (yes/no)] and eGFR (≥ 20 to <30 mL/min/1.73^2; or ≥ 30 to < 45 mL/min/1.73^2; or ≥45 mL/min/1.73^2). The total duration of participation will be approximately 22 to 24weeks. ;
