High- versus low-dose iron treatment for adults on peritoneal dialysis (PALaDIN)

Proactive High Dose Versus Low-dose Reactive Intravenous or Oral Iron in People on Peritoneal Dialysis (PALaDIN) - an Open-label, Feasibility Randomised Study

Phase 3 Interventional Hull University Teaching Hospitals NHS Trust · NCT06884280

This project will see if higher-dose versus lower-dose iron treatment helps adults on peritoneal dialysis with iron-deficiency anaemia keep their iron and haemoglobin levels more stable.

What this trial studies

Adults on peritoneal dialysis who meet laboratory criteria for iron deficiency are enrolled and assigned to different iron dosing strategies using iron isomaltoside (Monofer) or ferrous sulfate according to the protocol. Key eligibility includes age ≥18, ferritin <700 µg/L, transferrin saturation <40%, no recent IV iron, and at least four weeks on maintenance peritoneal dialysis. The study collects blood iron indices, haemoglobin, treatment tolerability, and completion rates over follow-up to determine which dosing approach gives the clearest, most patient-relevant benefit. Safety monitoring includes liver enzymes and exclusion criteria such as haemochromatosis, recent HIF-PHI use, or anticipated need for transfusion or major surgery.

Who should consider this trial

Good fit: Adults on maintenance peritoneal dialysis with iron deficiency (ferritin <700 µg/L and transferrin saturation <40%), not recently given IV iron and expected to remain on peritoneal dialysis for the study duration.

Not a fit: Patients with haemochromatosis or marked liver enzyme elevation, those likely to need imminent transfusion or currently receiving end-of-life care, women of childbearing potential not using effective contraception, or those unable to attend the Hull site are unlikely to receive benefit or are excluded.

Why it matters

Potential benefit: If successful, this could identify an optimal iron dosing approach to improve anaemia control and reduce complications and treatment burden for people on peritoneal dialysis.

How similar studies have performed: Intravenous iron has shown benefit for anaemia management in dialysis populations, especially haemodialysis, but the best dosing strategy for peritoneal dialysis patients is less well established.

Eligibility criteria

Inclusion Criteria:

* Males and females aged ≥18 years.
