Rheopheresis as an add-on treatment for calciphylaxis in people on hemodialysis

Official title: Efficacy of Rheopheresis as Adjuvant Treatment of Calciphylaxis in Hemodialysis Patients : a Prospective Randomized Controled Single-blind Trial

Run by University Hospital, Lille · NCT04654000 · Data updated 2026-11-12

This trial will try adding rheopheresis to usual care to see if it helps people on hemodialysis with ulcerated or necrotic calciphylaxis skin lesions heal and improve symptoms.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with end-stage renal disease on hemodialysis who have at least one ulcerated or necrotic calciphylaxis lesion, weigh more than 30 kg, and can give informed consent.

Probably not a fit

Patients with very limited life expectancy (<6 months), uncontrolled infection, albumin allergy, inability to stop certain anticoagulants, severe cognitive impairment, or pregnancy are unlikely to benefit or are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, randomized, controlled trial comparing rheopheresis added to standard care versus standard care with sham-apheresis in patients with ulcerated or necrotic calciphylaxis on hemodialysis. Rheopheresis is a double-filtration plasmapheresis that removes selected high–molecular-weight plasma proteins linked to vascular inflammation and thrombosis. Participants meeting inclusion criteria will be randomized to receive active rheopheresis procedures or sham procedures in addition to usual multidisciplinary management. The trial will monitor safety and clinical outcomes such as lesion healing, pain, and progression over a defined follow-up period.

Why it matters

Potential benefit: If successful, adding rheopheresis could speed healing of skin lesions, reduce pain and complications, and improve outcomes for dialysis patients with calciphylaxis.

How similar studies have gone: Rheopheresis has prior use in other microcirculatory disorders, but randomized evidence specifically for calciphylaxis is very limited and this application is largely untested.
