Use of a Novel SUBCUTaneous Preparation of Furosemide to Facilitate Early Supported Discharge of Patients With Heart Failure

Summary

To investigate whether an early supported discharge strategy for patients admitted to hospital because of HF, using a pH neutral subcutaneous (SC) furosemide formulation (SQINFurosemide) at home (delivered by non-CE marked SQINInfusor), compared to a usual care strategy with intravenous (IV) furosemide in hospital, results in an increased number of days spent alive and out of hospital (DAOH) at 30 days.

Eligibility

Inclusion Criteria:

* Written informed consent
* Male or female ≥18 years of age
* Meet European Society of Cardiology (ESC) criteria for diagnosis of HF1

  * Elevated natriuretic peptide (BNP\> 100 pg/mL or NTproBNP \>300 pg/mL)
  * Signs and symptoms of HF
  * Echocardiographic structural or functional abnormality according to ESC guidelines
* Have received IV diuretic for treatment of HF within preceding 24 hours
* Be less than 96 hours after admission to hospital
* Requiring IV diuretics for a minimum of 24 hours after screening
* Have an echocardiogram or other assessment of cardiac structure and function within preceding 12 months or at screening
* Have a home environment that allows the patient to be able to mobilise within their residence and be able to pass urine into their toilet (unless catheterised)
* Able to operate (or has a caregiver who can operate) SQIN-Infusor (as assessed by training on a dummy device at screening)

Exclusion Criteria:

* Unable to consent due to significant cognitive impairment or lack of capacity
* Unable to operate SQIN-Infusor (or no caregiver who is able to operate the device)
* Geographical reasons preventing follow-up visits
* Pregnancy or breast-feeding
* Requiring treatment with IV furosemide \>250 mg furosemide per day in the opinion of the treating physician
* Left sided valve disease with planned surgery or percutaneous intervention
* Type 1 myocardial infarction during index hospitalisation (participants with type 2 myocardial infarction can be included)2
* Renal impairment, defined as estimated glomerular filtration rate (eGFR) \< 20 mL/min/1.73 m 2 at screening
* Reasons (other than HF) which may prevent discharge from hospital, such as social circumstances or other significant medical condition (at investigator discretion)
* Women of childbearing potential
* Patient on active cardiac transplant waiting list
* Patient requiring on-going inotropic, vasopressor or intraaortic balloon pump support
* Potassium \<3.0 mmol/L
* Potassium \>6.0 mmol/L
* Sodium \<125 mmol/L
* Any surgical or medical condition which, in the opinion of the investigator, may pose an undue risk to the subject, interfere with participation in the study or which may affect the integrity of the data
