Enhancing Fluid Transfer Through the Skin, by Increased Sweat Rate, on Hemodialysis Patients

Not Applicable

Completed

• Conditions: Chronic Kidney Diseases; Acute Kidney Failure
• Interventions: Device: The AquaPass System

• Registration Number: NCT06358365
• Lead Sponsor: AquaPass Medical Ltd.

Brief Summary

To demonstrate safety and performance of AquaPass System for improving fluid balance in hemo-dialysis patients, by increasing fluid loss via the skin.

Detailed Description

This study requires several investigational tests, exams, and data collection procedures to be performed by the participants. These procedures are listed in abbreviated format in the Schedule of Assessments/Activities table. The final eligibility of the trial will be confirmed after a 2-hour acclimatization session. The trial-specific procedures must not be performed until the participant has signed a written informed consent form, which has been approved by the site's Institutional Review Board.

The investigator or designee, who is trained in the clinical investigation plan, will explain the nature and scope of the trial to the participant. They will also discuss the potential risks and benefits of participation and answer any questions the participant may have. If the participant agrees to participate, they must sign the informed consent form. The investigator/designee must also sign the form before the participant can be enrolled in the trial. Any additional persons required by the site's Institutional Review Board to sign the informed consent form must also comply.

Each participant's study duration will be approximately 8 weeks. The study duration will be identical for all participants, as follows:

Screening Period: This period will last up to 7 days, during which time the participant's eligibility for the trial will be determined.

Observation Period: This period will last 3 weeks, during which the participant will come to the medical study center for weekly assessments.

Procedure Period: This period will last 4 weeks, during which time the participant will undergo 2-3 procedures with the AquaPass device each week. These procedures will be in addition to their regular hemodialysis treatment. The participant will undergo 2 procedures during the weekend, and each procedure will last 3-8 hours.

Follow-Up: This period will last 7(±1) days from the last procedure. During this period, the participant's health status will be monitored.

In summary, the study requires participants to undergo several investigational tests, exams, and data collection procedures. The study duration for each participant will be approximately 8 weeks, during which time they will undergo a screening period, observation period, procedure period, and follow-up period. All participants must provide written informed consent before any trial-specific procedures can be performed.

Arm && Interventions

Group	Intervention	Description
adult patients undergoing regular hemodialysis	The AquaPass System	This study will be a crossover study with one center and an open label design. Patients who sign the informed consent form and meet the inclusion and exclusion criteria will undergo a 2-hour acclimatization period to verify their ability to adhere to the AquaPass procedure. Once enrolled, patients will undergo a 3-week observation period where they will continue with their regular hemodialysis treatment with no changes. Study endpoint parameters will be assessed during this observation period and used as a control group. After the observation period, patients will undergo the AquaPass procedure 2-3 times a week for 4 weeks. Study assessments will be conducted at the beginning of each week during the patient's dialysis session.

Primary Outcome Measures

Name	Time	Method
Device related Adverse Events	Up to 60 Days	Safety evaluation of device-related adverse effects
Differences in weight gain over the long interdialytic period	Up to 50 days	weight at the end of the last Hemodialysis session before AquaPass therapy subtracted from the weight in the morning of the first Hemodialysis session of the week after AquaPass therapy.

Secondary Outcome Measures

Name	Time	Method
Effect on Quality of Life	up to 50 days	change in the quality of life measured by the Kansas City Cardiomyopathy Questionnaire. In this questionnaire the minimum score is '0' and the maximum is '100', and higher scores represent a better outcome for the patient.
Changes in NT-proBNP	Up to 50 days	Changes in biomarkers of congestion
Changes in Blood Urea Nitrogen	Up to 50 days	Changes in Blood Urea Nitrogen levels
Affect on Ultrafiltration Rates after the long inter dialytic gap	up to 28 days	Evaluation of the changes in ultrafiltration rates between the control phase and the Aquapass phase in the first dialysis session after the long interdialytic period
