Avoiding Treatment in the Hospital With Furoscix for the Management of Congestion in Heart Failure - A Pilot Study (AT HOME-HF)
A Multicenter, Randomized, Open Label, Controlled Study Evaluating the Effectiveness and Safety of Furoscix On-Body Infusor vs Continued Medical Therapy for Worsening Heart Failure
This is a multicenter, randomized, open label, controlled study evaluating the effectiveness, and safety of the Furoscix Infusor vs continued medical therapy in patients with chronic heart failure and fluid overload requiring augmentation in diuretic therapy outside of acute care setting.
The study drug, Furoscix (furosemide injection 8 mg/ml), is a furosemide solution buffered to a neutral pH containing 80 mg/10 mL for subcutaneous administration over 5 hours via the Furoscix Infusor.
The study objectives are:
- To provide pilot data on the effectiveness and safety to inform a pivotal trial.
- To inform population enrichment strategies
- To refine pivotal trial endpoints and analytical methods
- To identify operational challenges of study design
- To assess patient adherence, competence, and experience
- To familiarize staff and patients with device application and use

Detailed Description
The purpose of this study is to evaluate the effectiveness and safety of the Furoscix Infusor vs continued medical therapy in patients with chronic heart failure and fluid overload requiring augmentation in diuretic therapy outside of acute care setting. 51 patients will be randomly assigned (2:1) to receive Furoscix vs continued medical therapy.
The Treatment Phase comprises a pre-programmed bi-phasic 5-hour drug administration of Furoscix (80 mg/10 mL) via the On-body Infusor. Subjects and/or their caregivers will be trained on device preparation, placement and removal in accordance with product instructions of use (IFU). Subjects should be transitioned back to their oral maintenance diuretic regimen when clinically indicated at the discretion of the investigator.
Over the initial 7 days, all subjects will receive daily clinic or phone follow-up by the study staff. Decision of treatment with Furoscix in the intervention arm as well as changes in oral diuretic dosing in the control arm will be determined by the treating physician in coordination with the study nurse. Safety labs will be done on Days 1, 3, 7 and 30.
After Subjects have been transitioned to their oral maintenance diuretic regimen, additional doses of Furoscix (for Furoscix group) or IV diuretics (for Treat as Usual group) can be prescribed during the 30-day study period as needed based on the presence of congestion symptoms (e.g. dyspnea, edema, and/or excess weight gain) as determined by the investigator.
The Follow-Up Phase will include a visit to the clinic on Day 30 +/- 5 days where effectiveness and safety assessments will be performed including limited physical exam (including NYHA Class), Composite Congestion Score (CCS), 5-point Current Dyspnea Score, 7-point Dyspnea Score, vital signs, laboratory analyses, KCCQ-12, Visual Analog Score (VAS), 6MWT and adverse events.

Experimental: Furoscix Infusor
Furoscix (furosemide injection, 8 mg/mL) administered subcutaneously over 5 hours via the Furoscix Infusor.
The Infusor is applied to the abdomen via a medical grade adhesive and delivers a subcutaneous infusion of Furoscix through a pre-programmed, biphasic delivery profile with 30 mg (3.75 mL) administered over the first hour, followed by 12.5 mg (1.56 mL) per hour for the subsequent 4 hours (Total dose is 80 mg (10 mL) over 5 hours).
|
Furoscix Infusor, a drug-device combination product for subcutaneous delivery of Furoscix, buffered furosemide injection, 8 mg/mL (total dose = 80 mg dose) administered subcutaneously for 5 hours.
|
No Intervention: Continued Medical Therapy
The subjects enrolled in this arm will receive treatment as usual

Visual Analog Scale (VAS)
Time Frame: Baseline, 7 Days, 30 Days
|
The patient global assessment VAS is a patient-reported assessment of how good or bad a patient feels their health is on a given day.
It is reported on a visual scale of 0 to 100, with 0 being the worst health they can imagine and 100 being the best health they can imagine.
|
Baseline, 7 Days, 30 Days
|
Composite Congestion Score (CCS)
Time Frame: Baseline, Day 7, Day 30
|
The composite congestion score (ccs) is calculated by summing the individual scores for orthopnea, pedal edema and jugular venous distension. The investigator-assessed the signs and symptoms of congestion (orthopnea, pedal edema, and jugular venous distension) on a 4-point grading scale ranging from 0 to 3. Higher score indicates greater severity of symptoms ranging from 0 to 9. |
