Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have been on chronic hemodialysis for at least six months and meet specific clinical criteria.

Probably not a fit

Patients with active bleeding, uncontrolled diabetes, or other severe comorbidities may not benefit from this study.

What this trial studies

This observational study evaluates the effectiveness of different hemodialysis techniques in removing uremic toxins from patients with chronic end-stage renal disease. It compares the Theranova 400™ filter used in expanded hemodialysis (HDx) with high-flux hemodialysis (HF HD), online hemodiafiltration (OL-HDF), and high-flux hemodiafiltration (HFR). The study will analyze data from approximately 50 patients treated over a four-year period, focusing on mid-term outcomes and the potential benefits of personalized therapy for frail patients. The study is non-interventional, relying on standard clinical practices and existing patient data.

Why it matters

Potential benefit: If successful, this study could lead to improved dialysis techniques that better remove toxins and enhance the quality of life for patients with chronic kidney failure.

How similar studies have gone: While there have been studies comparing some hemodialysis techniques, this specific comparison of HDx with HFR is novel and has not been extensively tested.
