Assessing the safety and efficacy of NeoKidney® for patients with end-stage renal disease on short daily hemodialysis

Safety and Efficacy Assessments of NeoKidney®, a New Sorbent-based Hemodialysis Device, in ESRD Patients Treated With Short Daily Hemodialysis: a First in Human Use.

Not applicable Interventional Nextkidney S.A. · NCT06024135

This study is testing a new device called NeoKidney® to see if it helps people with end-stage kidney disease feel better while they receive short daily hemodialysis.

What this trial studies

This clinical investigation evaluates the safety and efficacy of the NeoKidney® device in patients with end-stage renal disease (ESRD) who are undergoing short daily hemodialysis. Participants will progressively use the NeoKidney® device over three weeks, starting with one session in the first week, followed by two sessions in the second week, and then six consecutive days in the third week, with other sessions conducted using their usual home device. The study aims to determine how well the NeoKidney® performs compared to standard treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and over who have been on short daily hemodialysis for at least three months.

Not a fit: Patients with a post-dialysis body weight below 41.0 kg or significant anemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this could provide a more effective and safer hemodialysis option for ESRD patients.

How similar studies have performed: While similar approaches have been explored, the NeoKidney® device represents a novel intervention in this specific patient population.
