Heart Failure-Kidney Disease Research Trial (22 Weeks)

Treatment: Oral Age: 21 Years

Adults aged 21 years or older with a diagnosis of stable symptomatic heart failure (NYHA class II-III), and a medical history of typical symptoms and signs of heart failure who are currently receiving loop diuretic treatment, may qualify to participate. Individuals must have documented LVEF (left ventricular ejection fraction) below 55% measured within the last 12 months prior to screening. The study is looking for heart failure patients who have chronic kidney disease (with an estimated glomerular filtration rate ≥30 and ≤60 mL/min). Stable background treatment for heart failure, hypertension, diabetes mellitus, or renal disease for at least 3 weeks prior to randomization is required.

Participants will receive oral medication (investigational study drug and dapagliflozin), either in combination, alone or as placebo. Study medication and study-related procedures will be provided at no cost. Reimbursement for study-related expenses may be provided.

Length of study participation will last about 22 weeks and involve about 11 visits to the study centre.

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

ClinicalTrials.gov ID




Study Description

  • Brief 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]).
