Furosemide Pharmacodynamics and Pharmacokinetics After Subcutaneous or Oral Administration (FUROPHARM-HF)

This is an interventional treatment trial for Heart Failure focused on measuring Chronic Fluid Overload Read More

Inclusion Criteria:

• Written informed consent obtained before any assessment is performed
• Male and female subjects ≥18 years of age, with body weight <120 kg and body mass index (BMI) <30 kg/m2
• Female subjects must be at least 2 years post-menopausal
• Participant must have been on oral furosemide (40 mg oid or bid) or therapeutic equivalent (bumetanide 1 mg oid or bid) for a period 90 days before the first dose of study medication
• History of chronic heart failure according to 2012 ESC guidelines with presence of moderate symptoms of chronic fluid overload. Chronic fluid overload is defined as presence of stable signs and symptoms of heart failure and congestion, like dyspnea at mild exertion or minimal exertion, pulmonary congestion and/or peripheral edema at the time of presentation in combination with elevated levels on natriuretic peptides (NT-proBNP > 300 ng/L)
• In the opinion of the investigator, able to participate in the study

Exclusion Criteria:

• Acute Decompensated Heart Failure (ADHF) or recent history of ADHF or significant worsening in their HF symptoms (within prior 2 weeks)
• Contraindication to furosemide
• Systolic BP (SBP) < 90 mm Hg
• Temperature > 38°C (oral or equivalent) or sepsis or active infection requiring i.v. anti-microbial treatment
• Serum sodium < 130 mmol/L and Serum potassium < 3.0 mmol/L
• Current or planned (throughout the completion of study drug infusion) treatment with any i.v. therapies, including inotropic agents, vasopressors, levosimendan, nesiritide or analogues; or mechanical support (intra-aortic balloon pump, endotracheal intubation, mechanical ventilation, or any ventricular assist device)
• History of gastric or intestinal surgery that may affect absorption of oral medication
• Presence or need for urinary catheterization
• Current or planned ultrafiltration, hemofiltration, or dialysis
• Impaired renal function defined as an estimated glomerular filtration rate (eGFR) on admission < 30 mL/min/1.73 m2 will be calculated as per standard at local laboratory
• Administration of intravenous radiographic contrast agent within 72 hours prior to screening or acute contrast-induced nephropathy at the time of screening
• Major surgery within 30 days prior to screening
• Administration of an investigational drug or implantation of investigational device, or participation in another trial, within 30 days before screening
• Inability to follow instructions or comply with procedures
• Any surgical or medical condition which in the opinion of the investigator may interfere with participation in the study or which may affect the outcome of the study
