New stem cell method aims to protect kids with rare immune disease
NCT ID NCT02737384
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a way to improve stem cell transplants for children with combined immunodeficiency (CID), a condition where the immune system doesn't work properly. The approach removed certain naive cells from the donor stem cells to try to prevent graft-versus-host disease (a serious complication) while keeping the donor's memory T cells to fight infections. Only 4 children were enrolled before the study ended early, so results are limited.
