Less dialysis, more kidney? study tests gentler start for kidney failure patients
NCT ID NCT03418181
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study tests whether starting haemodialysis with fewer sessions per week (twice instead of the standard three times) can help preserve patients' remaining natural kidney function. New dialysis patients who still have some kidney function are randomly assigned to either standard thrice-weekly dialysis or an incremental approach that adjusts dialysis dose based on their natural kidney function. The goal is to see if this gentler start is feasible and whether it slows the loss of native kidney function, which could improve quality of life and survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- incremental haemodialysis (starting with twice-weekly sessions, adjusted based on remaining kidney function)
- What this could lead to
- If successful, this approach could help new dialysis patients preserve their natural kidney function longer, potentially reducing dietary restrictions and improving survival.
- What could go wrong
- This is a small feasibility study, not designed to prove effectiveness. The benefits of incremental dialysis are uncertain, and some patients may need more frequent sessions to manage fluid or electrolyte imbalances.

Inclusion Criteria: * Age ≥ 18 years * Advanced renal failure due to underlying primary kidney disease and established as a new starter on haemodialysis within the previous 3 months * Residual Kidney Function likely to permit twice weekly dialysis as defined by interdialytic urea clearance ≥3ml/min/1.73m2 BSA measured routinely as part of standard care * Sufficient understanding of the study procedures and requirements including capacity for explicit agreement to be randomised to standard or incremental HD regimens Exclusion Criteria: * Planned organ transplantation and already on another interventional trial within 3 months from study screening * Anticipated requirement for high-volume ultrafiltration on dialysis (e.g. subjects with daily enteral or parenteral nutrition) * Blood-borne virus positivity * Subjects unable to comply with requirement for monthly interdialytic urine collection. * Pregnancy * Prognosis \<12 months as judged by PI
