Study Details

Study Description

Brief Summary

The study is to evaluate the safe admission avoidance and the overall economic impact associated with management of worsening HF using the drug-device combination product, the Furoscix Infusor, outside the hospital setting in patients initially presenting to the emergency department.

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:
  1. To evaluate differences in healthcare resource utilization and direct medical costs for patients treated with the Furoscix Infusor outside the hospital versus patients receiving intravenous furosemide for ≤ 72 hours in the hospital setting for 30 days post-discharge from the emergency department.

  2. To evaluate the safety of Furoscix administered outside the hospital.

  3. To evaluate and describe quality of life and patient satisfaction for patients who receive the Furoscix Infusor outside the hospital setting.

Condition or Disease Intervention/Treatment Phase
  • Combination Product: Furoscix Infusor
Phase 3

Detailed Description

This adaptive clinical trial will include a prospective treatment arm (i.e., Furoscix administered via the Furoscix Infusor) administered outside the hospital that will be compared to a propensity-matched historical control arm of patients admitted to the hospital for ≤ 72 hours (i.e., Treatment As Usual (TAU)) that will be derived from administrative claims data. Eligible patients for the Furoscix arm will be patients with HF and fluid overload who initially present to the emergency department (ED) and who are expected to require parenteral diuresis.

If it is determined by the investigator that the patient requires parenteral diuresis or continued diuresis outside of the ED care setting and meets all study eligibility criteria, he/she may be consented and enrolled into the study.

The treatment comprises a preprogrammed bi-phasic 5-hour drug administration. Subjects will be instructed on the use of the Furoscix Infusor by the investigator and/or study staff in accordance with the instructions for use. The initial dose of the study product may be administered in the ED or at home. Additional doses will be provided to the subject for self-administration or administration by a caregiver in the home setting as directed by the investigator or study staff. The total duration in days and total number of doses of the initial therapy will be determined by the investigator based on an estimated volume of diuresis desired to transition patient back to their oral diuretic maintenance therapy. Subjects will receive scheduled at-home telephone calls from a HF nurse on Days 1 and 7 and one call between Days 14-21. Planned in-clinic visits will be conducted between Day 2-4 and then Day 30. Unscheduled at-home telephone calls by a HF nurse and unscheduled in-clinic visits may be performed if felt clinically indicated by the study team or the clinical provider.

The study period will be up to 30 days after enrollment. All outcomes will be assessed up to 30 days after the initial discharge from the emergency department.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Furoscix Infusor Prospective Treatment

Furoscix (furosemide injection, 8 mg/mL) administered subcutaneously over 5 hours via the Furoscix Infusor outside the hospital.

Combination Product: Furoscix Infusor
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: Propensity-Matched Historical Control

The control arm will be populated with claims data for patients with HF and fluid overload who presented to the emergency department and were admitted to the hospital for ≤ 72 hours for the treatment of HF with intravenous diuretics. Patients admitted for diuresis-only will be identified by using diagnostic codes for admittance from a claims database.

Outcome Measures

Primary Outcome Measures

  1. Difference in total HF-attributable direct medical costs [30 Days]

    The difference in the overall and heart failure related healthcare costs between subjects treated with the Furoscix Infusor through 30 days post discharge from the emergency department versus matched controls treated in the hospital for ≤ 72 hours through 30 days post discharge.

Secondary Outcome Measures

  1. Hospital admissions between the Furoscix Infusor arm and propensity-matched (treatment as usual) arm [30 Days]

    To compare the Furoscix Infusor versus TAU with respect to number of hospital admissions and duration within 30 days post discharge from emergency department.

  2. HF-related hospital admissions between the Furoscix Infusor arm and propensity-matched (treatment as usual) arm [30 Days]

    To compare the Furoscix Infusor versus TAU with respect to number of HF-related hospital admissions and duration within 30 days post discharge from emergency department.

  3. HF-related emergency department visits between the Furoscix Infusor arm and propensity-matched (treatment as usual) arm [30 Days]

    To compare the Furoscix Infusor versus TAU with respect to number of HF-related emergency department visits within 30 days post discharge from emergency department.

  4. HF-related clinic visits between the Furoscix Infusor arm and propensity-matched (treatment as usual) arm [30 Days]
