Finerenone and Cardiac Remodeling

Prior treatment

• Currently on a mineralocorticoid receptor antagonist (MRA) or in the opinion of the investigator, an MRA is either clinically indicated or contraindicated (e.g. history of marked hyperkalemia, marked hemodynamic stress, intolerance to MRAs) - individuals who previously experienced gynecomastia with spironolactone may be eligible if they meet all the inclusion criteria and none of the exclusion criteria;
• 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;
• 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;
• Planned or previous cardiac surgery or major non-cardiac surgery ≤45 days of screening;
• Planned or previous percutaneous coronary intervention ≤45 days of screening;
• Stroke or transient ischemic stroke ≤90 days before randomization;
• Participation in an investigational study ≤15 days prior to screening, or during study.

Other illness

• History of pulmonary arterial hypertension;
• Type 1 diabetes mellitus;
• History of cardiac device implant (e.g. implantable cardioverter defibrillator/cardiac resynchronization therapy/pacemaker) or planned device implant ≤90 days after screening;
• 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;
• Myocardial infarction ≤45 days of screening;
• Severe valvular heart disease;
• Addison's disease;
• Individuals who are heart or kidney transplant recipients or who are (or are expected to be) listed for heart transplant, kidney dialysis or a kidney transplant ≤12 months of screening;
• Any other known condition or therapy which would make the individual unsuitable for this trial (e.g. hepatic insufficiency, liver biomarkers \>3X upper limit of normal, chronic pulmonary disease, life threatening arrhythmia, uncontrolled arrhythmia) or not allow participation for the full planned trial duration (e.g. active malignancy ≤24 months of screening or condition limiting life expectancy to \<12 months);
• Allergy to finerenone (or its excipients);
• Allergy to gadolinium;

Lab values

• 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;
• Known persistent hypoalbuminemia (≤30 g/L on \>1 measurement within last 6 months);
• LVEF \<40% per the most current echocardiogram or MRI;

Other

• Females who are planning to become pregnant, are breastfeeding or are planning to breastfeed;
• 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;
• UACR ≥565 mg/mmol at the time of screening;
• Seated systolic blood pressure \<110 mmHg at the time of screening;
• Body mass index ≥40 kg/m\^2;
• Contraindication or inability to undergo MRI;

• Individuals ≥18 years of age who are willing and able to provide signed informed consent
• Evidence of left ventricular (LV) hypertrophy ≤12 months prior to or at screening showing at least one (≥1) of the following:
  • Interventricular septal (IVS) thickness by echocardiography: Female ≥1.2 cm or Male ≥1.3 cm
  • Posterior wall (PW) thickness by echocardiography: Female ≥1.2 cm or Male ≥1.3 cm
  • Left ventricular mass indexed to baseline body surface area (LVMi) by echocardiography: Female \>95 g⁄m\^2 or Male \>115 g⁄m\^2
  • LVMi (with papillary muscles included in the LV blood pool) by cMRI: Female \>59 g⁄m\^2 or Male \>75 g⁄m\^2
  • LVMi (if the papillary muscles are included in the LVM) by cMRI: Female \>68 g⁄m\^2 or Male \>85 g⁄m\^2
• The presence of at least one (≥1) of the following risk factors:
  • History of heart failure with preserved ejection fraction (left ventricular ejection fraction \[LVEF\] ≥50%);
  • Type 2 diabetes mellitus;
  • Estimated glomerular filtration rate (eGFR) ≥25 and \<75 mL/min/1.73 m\^2;
  • Urine albumin-creatinine ratio (UACR) \>3.39 mg/mmol and \<565 mg/mmol;

  • IVS ≥1.4 cm;
  • PW ≥1.4 cm;
  • LVMi ≥125 g⁄m\^2 for males and ≥105 g⁄m\^2 for females (by echocardiography);
  • N-terminal pro-B-type natriuretic peptide (NT-proBNP; within past 6 months) ≥150 pg/mL if in sinus rhythm or ≥450 pg/mL if atrial fibrillation is present.
  • Females who are of childbearing age can only be included if I. they are postmenopausal (i.e. no menstruation for at least one \[≥1\] year) or have had a surgical procedure ≥6 months at screening that prevents them from becoming pregnant; or II. the result of their pregnancy test at the baseline visit is negative, and they agree to use medically acceptable contraception methods to avoid pregnancy for the duration of the trial and for 1 month after taking the last dose of the assigned investigational product.
