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]).

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.

AZD9977 Dose A + dapagliflozin 10 mg
AZD9977 Dose B + dapagliflozin 10 mg
AZD9977 Dose C + dapagliflozin 10 mg
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.
