Efficacy and Safety of corticoSTEROids Added to Standard Therapy in Patients With Acute Heart Failure (STERO-AHF)

• Status: Not yet recruiting
• Trial end date: 2025-12-01
• Target enrollment: 0
• Participant gender: All

Summary

STERO-AHF is a pilot, prospective, multicenter, randomized, open-label, controlled study aimed to evaluate the diuretic efficacy and early clinical benefit of corticosteroid therapy administered for 7 days, in addition to standard therapy, in patients hospitalized for acute heart failure (AHF) and with evidence of insufficient diuretic response. Eligible patients will be randomized 1:1 to receive either standard-of-care alone (control group) or standard-of-care plus corticosteroid therapy (experimental group) for up to 7 days. Patients will be followed to 30 days.

Criteria

Inclusion criteria:

1. Full age of consent at screening (at least ≥18 years old according to local legislation).

2. Able to provide written informed consent or a legally authorized representative is able to provide written informed consent.

3. Hospitalized for AHF, either de novo or decompensated chronic HF, regardless of LVEF.

4. Treatment with a minimum single dose of 60 mg of intravenous furosemide or equivalent intravenous loop diuretic dose (defined as 30 mg of torsemide or 1.5 mg of bumetanide) at any time between presentation and the end of screening.

5. Early insufficient diuretic response in patients receiving an initial loop diuretic dose >125 mg of intravenous furosemide or equivalent OR persistent insufficient diuretic response in patients receiving an initial loop diuretic dose <125 mg of intravenous furosemide or equivalent. Insufficient diuretic response will be assessed at 2-12 hours after the first intravenous loop diuretic dose administration, according to the latest 2021 ESC guidelines on the management of acute and chronic HF. An early insufficient diuretic response will be defined as either urinary sodium <70 mEq/L at a single spot urinary sodium analysis performed at 2 hours or an average urine output <150 mL/h in the first 6 hours after first intravenous diuretic administration. Persistent insufficient diuretic response will be defined as either urinary sodium <70 mEq/L at a single spot urinary sodium analysis performed 2 hours after the second intravenous loop diuretic dose (double dose) or an average urine output <150 mL/h in the 6 hours after the second intravenous loop diuretic dose (double dose).

6. New York Heart Association functional class II, III or IV at screening.

7. Elevated NT-proBNP ≥1400 pg/mL or BNP ≥350 pg/mL according to the local laboratory for patients without atrial fibrillation, or NT-proBNP ≥2200 pg/mL or BNP ≥550 pg/mL for patients with atrial fibrillation at the time of admission and/or in the 72 hours prior to hospital admission.

8. Elevated CRP ≥20 mg/L according to the local laboratory, measured during the current hospitalization.

9. Eligible for randomization within the first 24 hours from presentation.

Exclusion criteria:

1. Dyspnea due to non-cardiac causes.

2. Systolic blood pressure <90 mmHg or >180 mmHg at time of screening and randomization.

3. Current hospitalization for AHF primarily caused by pulmonary embolism, cerebrovascular event, or acute myocardial infarction.

4. Current hospitalization for AHF not caused primarily by volume overload; for example, triggered by significant arrhythmia (e.g., sustained ventricular tachycardia [VT], or atrial fibrillation/flutter with sustained ventricular response >120 beats per minute, or bradycardia with sustained ventricular rate <45 beats per minute), infection/sepsis, severe anemia, uncorrected thyroid disease, or acute exacerbation of chronic obstructive pulmonary disease.

5. Temperature >38.0 °C (oral or equivalent), sepsis, septic shock, or evidence of active infection (either bacterial, fungal or viral) requiring new oral or intravenous anti-microbial treatment (either antibacterial, antifungal or antiviral therapy).

6. History of chronic infections, latent infections, chronic inflammatory or immunosuppressive disorders, chronic immunosuppressive therapy, ongoing chemotherapy or immunotherapy, or chronic anti-microbial therapy (either prophylactic or suppressive).

7. Current treatment with intravenous corticosteroids or chronic oral corticosteroid therapy for any other condition and of any duration in the past 6 months prior to randomization.

8. Documented active or history of hypocortisolism or hypercortisolism caused by primary/secondary adrenal gland disorders, pituitary disorders, iatrogenic conditions, or genetic forms (e.g., adrenal insufficiency, Cushing disease or Cushing syndrome, prior chronic long-standing corticosteroid therapy).

9. Decompensated diabetes mellitus, defined as the presence of diabetic ketoacidosis, hyperglycemic hyperosmolar state, or glycemia > 250 mg/dL as measured at the latest local laboratory exams performed during hospitalization.

10. Acute coronary syndrome / myocardial infarction, stroke, transient ischemic attack, or intracranial bleeding in the past 90 days prior to randomization.

11. Any of the following major interventions performed in the past 30 days prior to randomization or planned during the current admission: major cardiac surgery (e.g., coronary artery bypass graft or valve replacement), percutaneous coronary intervention, transcatheter aortic valve replacement, or percutaneous mitral valve repair (e.g., transcatheter edge-to-edge mitral valve repair); implantation of a cardiac resynchronization therapy device; implantation of a mechanical circulatory support (MCS) device; carotid artery disease revascularization (percutaneous intervention or surgery); or any other surgical procedure that is considered "major" according to investigator judgement.

12. Heart transplant recipient, or listed for heart transplant with expectation to receive transplant during the study period (according to investigator judgement), or currently using or planned for implantation of left ventricular assist device or intra-aortic balloon pump or any other MCS device, or planned inotropic support in an outpatient setting, or planned for palliative care for HF.

13. Hemodynamically significant (severe) uncorrected primary cardiac valvular disease planned for intervention during the study period. Secondary mitral regurgitation or tricuspid regurgitation due to dilated cardiomyopathy is not excluded unless planned for surgical or percutaneous intervention during the study period.
