Interventions
Device: AquaPass
Registration Number
NCT06401109
Lead Sponsor
AquaPass Medical Ltd.
Brief Summary

The AquaPass is a non-invasive, renal-intended system designed to enhance fluid transfer through the skin, by increasing sweat rate, to treat fluid overload in heart failure patients.

This study will further evaluate the safety, efficacy, and usability of the AquaPass system in the hospital and home settings.

Detailed Description

The AquaPass system is non-invasive and functions independently of the renal system, targeting the direct removal of fluids directly from the interstitial compartment through the skin, by activating the eccrine sweat glands.

The patient wears a component that is connected to a control unit, which induces warm air to create a controlled environment around the skin, stimulating sweat production. The sweat evaporates instantly, ensuring that the patient remains dry and comfortable.

In this study, the investigators would like to further investigate the efficacy of the system, when used in hospital settings in patients hospitalized for decompensated heart failure and fluid overload, and to continue the treatment in their homes, immediately after the hospitalization, for another 30 days.

Arm && Interventions
GroupInterventionDescription
AquaPassAquaPassPatients hospitalized with chronic heart failure symptoms and fluid overload will be treated in two phases: Phase 1: 'In Hospital' Phase: Patients will be enrolled in the study when admitted to the hospital with fluid overload. Use of the AquaPass system will be performed in the hospital, alongside diuretic therapy. Phase 2: 'At Home' Phase: Upon the investigator's decision at discharge, the patients will be enrolled in this phase of the study, and will receive AquaPass treatment sessions at their home.
Primary Outcome Measures
NameTimeMethod
Average Sweat Rate Per Hour per patient30 days

An average sweat rate of 150 ml/hr per patient at hospital and at home

Incidence of device- and procedure-related side-effects30 days

Incidences of system and treatment-related AEs and SAEs including symptomatic changes in vital signs

Secondary Outcome Measures
NameTimeMethod
Incidence of worsening renal function30 days

Incidence of worsening renal function, measured as an increase of Creatinine levels by \>0.5mg/dL

Changes in congestion score30 days

to evaluate the effect of the AquaPass treatment on congestion score

Changes in Diuretics Dose30 days

Documentation of changes in diuretics administration to assess safety and potential benefits with system use.

Fluid Overload Related Hospitalizations30 days

Hospitalization or ED visit for decompensated heart failure

Change of quality of life30 days

Assessment of the quality of life using the Kansas City Cardiomyopathy Questionnaire (KCCQ). The minimal score is zero '0' and the highest is '100' when higher scores represent a better outcome for the patient.

Changes in NT-ProBNP levels30 days

Changes in NT-ProBNP levels to demonstrate the system's safety and clinical performance

Change in body weight30 days

To evaluate the effectiveness of the AquaPass System. During the study patients will weighed before and after each treatment. The weight before the first treatment and the weight after the last treatment will be used to assess the treatment performance
