E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess whether the initiation of spironolactone or eplerenone plus standard of care compared to standard of care alone reduces the incidence rate for total heart failure (HF) hospitalizations or cardiovascular (CV) death in HFpEF, studied with the pragmatic Registry-based Randomized Clinical Trial (RRCT) methodology.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary efficacy objectives are to evaluate: 1. Time to CV death or first HF hospitalization 2. Time to CV death 3. Incidence rate for total HF hospitalizations 4. Time to HF hospitalization 5. Time to all-cause mortality 6. Incidence rate for total all-cause hospitalizations 7. Time to all-cause hospitalization 8. Incidence rate for all-cause hospitalization or all-cause mortality
Exploratory efficacy objectives are to evaluate: 1. Time to sudden death or aborted cardiac arrest 2. Time to acute coronary syndrome/acute myocardial infarction 3. Time to stroke 4. Time to hospitalization for hypokalemia 5. Time to new-onset atrial fibrillation (Sweden only) 6. Time to new-onset diabetes mellitus (Sweden only)
Safety objectives are to evaluate changes in potassium and renal function
Adherence will be evaluated by assessing time to cross-over (from spironolactone/ eplerenone to control and from control to spironolactone/ eplerenone) |
New secondary exploratory objectives 7. Incidence rate for total HF events, HF hospitalizations, or CV death 8. Incidence rate for unplanned non-hospitalized heart failure events 9. Time to unplanned non-hospitalized heart failure event 10. Incidence rate for total escalation of loop diuretic therapy, HF events, HF hospitalizations, or CV death 11. Incidence rate for escalation of loop diuretic therapy 12. Time to escalation of loop diuretic therapy

E.3 | Principal inclusion criteria |
1. Written informed consent 2. Age ≥50 years 3. Stable heart failure defined by symptoms and signs of heart failure as judged by local Investigator. Patients may be enrolled as an outpatient or at or close to the time of hospital discharge 4. Most recent left ventricular ejection fraction (LVEF) ≥40% 5. Elevated natriuretic peptide levels as defined by any of the following: a. most recent NT-proBNP >300 ng/L (or BNP >100 pg/mL) in sinus rhythm (at time of blood sampling); adjustments may be made for BMI according to table 3. b. most recent NT-proBNP >750 ng/L (or BNP >250 pg/mL) in atrial fibrillation (at time of blood sampling); adjustments may be made for BMI according to table 3. c. NT-proBNP >1200 ng/L (or BNP >400 pg/mL) within the last 12 months even if most recent value is lower 6. Regular use of loop diuretics, defined as daily or most days of the week 7. NYHA Class II-IV
|
|
E.4 | Principal exclusion criteria |
1. Previously enrolled in this study 2. Known EF < 40% ever 3. Current absolute indication or contraindication for MRA in judgement of Investigator. In the absence of absolute indication, patients currently treated with an MRA may have the MRA discontinued and then included in the trial, according to investigator judgement 4. Known chronic liver disease 5. Probable alternative explanations for symptoms such as: (a) Known primary cardiomyopathy that is hypertrophic with obstruction, constrictive, restrictive, infiltrative, or congenital (hypertrophic without current obstruction and other primary cardiomyopathies are allowed) (b) Primary valve disease (to exclude a patient, the valve disease must be primary AND the primary cause of the symptoms) (c) Significant chronic pulmonary disease requiring home O2 (d) Symptomatic anemia (hemoglobin is <10 g/dL (100 g/L) and this is the likely casue of the symptoms) (e) Right-sided HF not due to left sided HF
6. Heart transplant or LVAD recipient 7. Systolic blood pressure <90 or >160 8. K >5.0 mmol/L 9. eGFR by MDRD < 30 ml/min/1.73m2 10. Current dialysis 11.Current lithium use 12. Actual or potential for pregnancy 13. Participation in another clinical trial where a mineralcorticoid receptor antagonist is studied. Co-enrollment in trials and observational studies of other medical and device interventions is permitted 14. Not suitable in the opinion of the Investigator due to severe or terminal comorbidity with poor prognosis, or characteristics that may interfere with adherence to trial protocol
