E.3 | Principal inclusion criteria |
1. Participants must be at least 18 years of age or the legal age of consent in the jurisdiction in which the study is taking place at the time of signing the informed consent. 2. Prior chronic treatment, or prescription, with a loop diuretic (for example, furosemide, torsemide, bumetanide) for ≥30 days prior to the index event. Index event is defined as a recent hospitalization for HF requiring at least 2 doses of intravenous diuretics or an out- of- hospital encounter (for example, Emergency Room, clinic visit, infusion clinic, etc.) for HF requiring at least 2 doses of intravenous diuretics. 3. Chronic HF diagnosed for at least 3 months before V1 (screening). 4. Documented LVEF of ≥50% within 6 months prior to V1 (screening); as measured by echocardiography, radionuclide ventriculography, invasive angiography, MRI, or CT. 5. Have NYHA Class II-IV symptomatology as assessed at V1 (screening). 6. Had evidence of clinical HF syndrome consisting of A. Hospitalization for HF within the past 2 weeks from randomization, for WHF with intravascular volume overload (the index event), as determined by the investigator, based on appropriate supportive documentation at randomization, and defined by ≥2 of the following: • dyspnea • jugular venous distention • pitting edema in lower extremities (>1+) • ascites • pulmonary congestion on chest X-ray • pulmonary rales AND patient received treatment with IV diuretics. OR B. Treatment for an urgent visit outside of being hospitalized with WHF and intravascular volume overload (the index visit) requiring treatment with IV diuretics (defined as ≥2 IV doses) such as in the outpatient setting/emergency room/observation unit/infusion clinic with a clinical response within the past 2 weeks prior to randomization. Urgent visit is defined as an unplanned visit for HF defined by ≥2 of the following: • dyspnea • jugular venous distention • pitting edema in lower extremities (>1+) • ascites • pulmonary rales on lung examination. 7. NT-proBNP (>300 [sinus rhythm] or 900 pg/mL [atrial fibrillation or atrial flutter] OR BNP (>100 [sinus rhythm] or 300 pg/mL [atrial fibrillation or atrial flutter]) at screening (Visit 1, determined by local laboratory) Note: The presence or absence of atrial fibrillation or atrial flutter to determine the appropriate cut-off for a given BNP or NT-proBNP sample should be evaluated using the ECG performed at V1 (screening) prior to the collection of the BNP or NT-proBNP sample. 8. eGFR of >30 and <75 ml/min/1.73 m2 at V1 (screening; determined by local laboratory), derived from serum creatinine values, age, and sex based on the CKD-EPI equation (Inker et al. 2021). 9. Diuretic doses transitioned to oral loop diuretic (defined as: IV diuretic has been discontinued, AND chronic oral diuretic has been prescribed and/or administered) AFTER index event. Note: Do not need to be at a stable dose. 10. Males and females will be eligible for this study. a. Women not of childbearing potential may participate in this trial. (WOCBP are excluded from the trial.) See Appendix 10.4 for definitions. b. Males who agree to use highly effective or effective methods of contraception may participate in this trial. See Appendix 10.4 for definitions. Contraceptive use by participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. For the contraception requirements of this protocol, see Appendix 10.4. 11. Are capable of giving signed informed consent as described in Section 10.1.3, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol. Other inclusions 12. Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures, such as • self-inject intervention, and •store and take provided study interventions as directed. Note: Persons with physical limitations or unable to perform the injections must have the assistance of an individual trained to inject the intervention or come onsite for weekly injection.

E.4 | Principal exclusion criteria |
1. Prior documentation of LVEF ≤45% in the past 12 months. 2. Have had acute coronary syndrome or percutaneous coronary intervention, coronary artery bypass graft, cardiac mechanical support implantation, within 3 months prior to V2 (randomization), or any other cardiac surgery planned during the study. 3. Have had LVAD or cardiac transplantation or have cardiac transplantation planned during the study. 4. Have hypertrophic cardiomyopathy (obstructive or nonobstructive), restrictive cardiomyopathy, active myocarditis, constrictive pericarditis, cardiac sarcoidosis, known amyloid cardiomyopathy, or inherited cardiomyopathy. 5. Have uncontrolled arrhythmias other than permanent or persistent atrial fibrillation or atrial flutter. 6. Have a history of an uncorrected cyanotic cardiac disease affecting LV function. 7. Have a severe valvular disease. 8. The index admission or index visit for worsening chronic HF triggered primarily by • pulmonary embolism • cerebrovascular accident, or • acute myocardial infarction. 9. The index event for chronic worsening HF was not caused primarily by intravascular volume overload. For example, index event triggered by • significant arrhythmia, e.g., sustained ventricular tachycardia, or atrial fibrillation or flutter with sustained ventricular response >130 bpm, or bradycardia with sustained ventricular arrhythmia <45 bpm • infection • severe anemia, or • exacerbation of COPD. 10. Hospitalization for the index event lasting more than 2 weeks. 11. Are hospitalized for worsening HF event or received treatment for an urgent visit outside of being hospitalized with WHF, after V1 (screening) and before V2 (randomization) 12. Have severe COPD as defined by chronic oxygen dependence. Night-time oxygen is not exclusionary. 13. Uncorrected thyroid disease. 14. Documented hemoglobin <10 g/dL at V1 (screening). 15. Patients with uncorrected acute kidney injury at screening and/or on dialysis at screening 16. Have, within 3 years prior to screening, a history of an active or untreated malignancy or are in remission from a clinically significant malignancy. Exceptions: basal or squamous cell skin cancer. 17. Participants with personal or family history (first-degree relatives) of breast cancer. 18. Women with a history of a mammography with clinically significant abnormal findings. 19. Women with a history of clinically significant abnormal pap smear. 20. Patients have any history of platelet dysfunction, hemophilia, von Willebrand disease, coagulation disorder causing a bleeding diathesis, other bleeding diathesis, or significant, nontraumatic bleeding episodes, such as from a gastrointestinal source. 21. Symptomatic hypotension or a seated systolic BP <100 mmHg at the Screening Visit and on the day of V2 (randomization). 22. SBP ≥180 mmHg at V2 (randomization). 23. Have a history of or current significant psychiatric disorders considered clinically significant in the opinion of the investigator. 24. Chronic alcohol or drug abuse or any condition that, in the investigator’s opinion, makes them an unreliable trial participant or unlikely to complete the trial. 25. Any other clinical condition that would jeopardize the participant’s safety while participating in this trial or may prevent the participant from adhering to the trial protocol. Diagnostic assessments 26. Have laboratory values, in relation to the reference range ALT or AST >3.0x ULN or ALP >1.5x ULN or TBL >1.5x ULN, except for participants diagnosed with Gilbert’s syndrome 27. Have a suboptimal ECHO image quality assessed by a central imaging laboratory at screening. Prior/concomitant therapy 28. Have received IV inotropic therapy within 30 days before the Screening Visit Exception: renally dosed (≤3 μg/kg/min) IV dopamine is permitted. 29. Are currently treated with hormone replacement therapy at the time of screening, including but not limited to testosterone, estrogen, and DHEA. |
