Multiparametric Assessment of Cardiac Congestion in Outpatient Worsening Heart Failure

Completed

• Conditions: Heart Failure; Heart Decompensation

• Registration Number: NCT05747820
• Lead Sponsor: Corteria Pharmaceuticals

Brief Summary

This observational study is conducted to assess the evolution of multiple markers of congestion over 4 weeks after a worsening heart failure (WHF) event treated in an outpatient unit

Detailed Description

This is a multicenter, non-randomized, observational study designed to assess the evolution of multiple markers (physical, echocardiographic, and biomarkers) of congestion in 40 patients with chronic heart failure (CHF) treated over 4 weeks with 40 to 120 mg daily oral furosemide after an event of WHF treated in an outpatient unit. Patients at selected centers may participate in a telemetry ancillary study, in which real-time, continuous, non-invasive measurements of physiologic parameters of heart failure will be obtained through use of a wearable medical telemetry device.

Approximately 40 patients with CHF with reduced or mildly reduced left ventricular ejection fraction (EF \< 50%) who had an admission for WHF in the preceding 1-12 months and who develop symptoms of WHF over the week before presentation to an outpatient clinic will be enrolled. Patients will attend five outpatient visits over the course of 4 weeks.

At each visit, the patient's vital signs will be measured, clinical assessments (NYHA class, jugular vein distension, peripheral edema score, pulmonary rales) will be performed, and blood samples for central assays will be obtained. Detailed echocardiographic examination will be performed prior to enrolment in the first visit and at Visit 5.

Biomarkers related to cardiac and renal function will be measured in blood and urine samples at each visit.

Inclusion Criteria

1. Male or female patients ≥ 18 and < 80 years of age.

2. Previous documented hospital admission for HF between 12 months and 1 month prior to Screening.

3. Ambulatory patients with a diagnosis of stable NYHA class II - III HF with left ventricular ejection fraction <50%, who experience a worsening of heart failure (WHF), with worsening signs and/or symptoms of heart failure requiring institution or up titration of loop diuretic therapy, in the week preceding their visit to the outpatient HF clinic and with at the time of Screening:

   1. Dyspnea and at least one symptom of congestion (rales, orthopnea, peripheral oedema)
   2. Imaging confirmation of congestion as defined by either pulmonary congestion on chest X-ray or at least 2 B-lines by lung ultrasound.

4. Stable oral doses of ACEi, ARB or ARNi, beta-blocker, mineralocorticoid antagonist (MRA), and SGLT2i for > 1 month prior to screening.

5. An increase in the prescribed oral loop diuretic dose up to 120 mg daily furosemide or equivalent*for the treatment of the WHF event.

6. Biomarker profile suggestive of significant HF inclusive of NT-proBNP ≥1500 pg/ml, and elevated TnT from 15 ng/L (0.015 mcg/L) to 150 ng/L (0.15 mcg/L) or equivalent TnI using ultrasensitive assay.

7. Mild to moderate renal impairment (eGFR by the simplified MDRD formula of >30 and <60 ml/min/1.73 m2).

8. Written informed consent to participate in the study.

9. Ability to comply with all study requirements, without major morbidities compromising the patient's ability to participate and understand the study for 90 days.

Exclusion Criteria

1. Significant pulmonary disease contributing substantially to the patients' dyspnea such as FEV1< 1 liter or need for chronic steroid therapy.
2. Myocardial infarction, unstable angina, ICD or CRT implantation, or cardiac surgery, including percutaneous transluminal coronary intervention, within past 3 months.
3. History of heart transplant or on a transplant list or using or planned to be implanted with a ventricular assist device.
4. Significant uncontrolled arrythmia such as atrial fibrillation with a persistent heart rate > 120 beast/minute, any bradyarrhythmia with a persistent heart rate < 50 beats/min, sustained supraventricular tachycardia, any evidence of tri-fascicular block by ECG.
5. Sustained ventricular arrhythmia with syncopal episodes within past 3 months that is untreated.
6. Presence of any hemodynamically moderate or severe valvular stenosis or regurgitation, except for moderate mitral or tricuspid regurgitation secondary to left ventricular dilatation. Presence of hemodynamically significant obstructive lesions of left ventricular outflow tract.
7. Stroke or TIA within the past 3 months.
8. Primary or alcoholic liver disease considered to be life threatening.
9. Any episode of symptomatic hypotension within 3 months prior to screening.
