NCT ID NCT04654000

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a blood filtering procedure called rheopheresis to treat calciphylaxis, a rare condition causing painful skin wounds in people on dialysis. About 138 participants will receive either rheopheresis or a sham procedure to see if it helps wounds heal completely within 12 weeks. The goal is to find a better way to manage this serious complication.
