NCT ID NCT05148299

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tested a drug called pegcetacoplan in 12 adults who developed a serious blood clotting condition (TA-TMA) after a stem cell transplant. The goal was to see how the drug moves through the body, if it helps, and if it is safe. Researchers measured drug levels and markers of inflammation over 24 weeks.
