Finerenone and Cardiac Remodeling

What this study is about

The goal of this clinical trial is to learn if the drug finerenone (Karendia) can improve heart function in participants who are at risk for heart and kidney disease. The main question it aims to answer is whether adding finerenone to standard-of-care heart failure medical therapies will beneficially alter the heart structure and function of people who have risk factors for heart and kidney complications and whose left side of the heart is enlarged. The researchers will compare finerenone to a placebo (a look-alike substance that contains no drug) to see if finerenone improves heart structure and function. Participants will: * take a finerenone or a placebo tablet once a day for 12 months * have a cardiac magnetic resonance imaging (cMRI; a safe, non-invasive scan to measure heart mass, stiffness and function) test at the beginning of the study and 12 months later * visit the clinic after one, three, six and twelve months to assess overall health and/or perform blood or urine tests

• Males who are planning to either father a child or donate sperm for the duration of the trial and for 1 month after taking the last dose of the assigned IP;
• Serum potassium level ≥5 mmol/L at the time of screening;
• eGFR <25 mL/min/1.73 m\^2 at the time of screening or on kidney replacement therapy;

• Requirement of any intravenous (IV) vasodilating drug (e.g. nitrates, nitroprusside), any IV natriuretic peptide (e.g. nesiritide, carperitide), any IV positive inotropic agents, or mechanical support (intra-aortic balloon pump, endotracheal intubation, mechanical ventilation, or any ventricular assist device) ≤24 hours prior to randomization;
• Concomitant systemic therapy with potent cytochrome P450 isoenzyme 3A4 (CYP3A4) inhibitors (e.g. itraconazole, ritonavir, indinavir, cobicistat, clarithromycin) or moderate or potent CYP3A4 inducers, that cannot be discontinued 7 days prior to randomization and for the duration of the treatment period;
• History of cardiac device implant (e.g. implantable cardioverter defibrillator/cardiac resynchronization therapy/pacemaker) or planned device implant ≤90 days after screening;
• Hospitalized for heart failure (HF) requiring initiation or change in HF therapy or an urgent visit for HF requiring IV diuretic therapy, either ≤45 days prior to screening;
• LVEF <40% per the most current echocardiogram or MRI;
• Symptomatic bradycardia or second- or third-degree heart block without a pacemaker;
• History of peripartum cardiomyopathy, chemotherapy-induced cardiomyopathy, viral myocarditis, right HF in the absence of left-sided structural disease, pericardial constriction, hypertrophic cardiomyopathy, or infiltrative cardiomyopathy including amyloidosis;
