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.

Detailed description

HF is associated with frequent and lengthy hospitalisations. These hospitalisations are usually as a result of congestion, and the standard treatment of this is decongestion with intravenous (IV) diuretic (usually furosemide). This is usually delivered in a hospital setting. A new formulation of a pHneutral furosemide (SQIN-Furosemide) that can be delivered subcutaneously (SC) by a small patch pump (SQIN-Infusor) has been developed. Bioavailability of SQIN-Furosemide is similar to IV furosemide. This trial will test the efficacy and safety of novel SC furosemide 30mg/ml (SQIN-Furosemide), delivered in a home environment (compared to usual care strategy with IV furosemide delivered in secondary care) as part of a novel early supported discharge strategy in patients admitted to hospital with HF.

Conditions

• Heart Failure

Interventions

Type	Name	Description
DRUG	SQIN-Furosemide	The investigational furosemide formulation (SQIN-Furosemide) is a Captisol®buffered solution of 80mg furosemide in 2.7 mL (30 mg/mL) at pH 7.4 (range: 7.0 to 7.8). SC infusion will be performed using the SQIN-Infusor which will deliver 2.7 mL of the SQIN-Furosemide formulation (80mg) over approximately 5 hours, using a biphasic delivery profile.
DEVICE	SQIN-Infusor	The investigational device (SQIN-Infusor) is an on-body delivery system that consists of a RU, DU, plus a charger (Figure 2). For the purpose of SUBCUT-HF II trial, the RU will be used for multiple infusions for a single participant. The DU will be used only once per infusion and disposed of. The RU must be charged after each use and will not restart for the next infusion without charging. Charging takes up to 15 minutes. SQIN-Infusor is a bespoke system, adapted from the design of a SC insulin pump. The RU consists of the drive-unit, the controllers, the rechargeable battery, and the user interface.
