Modified immune cells aim to make stem cell transplants safer
NCT ID NCT06034535
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This Phase 2 trial tests a new method to improve stem cell transplants for people with blood disorders who lack a fully matched donor. Researchers will give patients specially processed donor immune cells (CD62L-depleted lymphocytes) alongside a T-cell depleted stem cell transplant. The goal is to reduce complications like graft failure and graft-versus-host disease, while improving survival. The study enrolls 23 participants and follows them for one year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CD62L-depleted donor lymphocytes
- What this could lead to
- If successful, this approach could reduce the risk of graft failure and severe graft-versus-host disease, making haploidentical transplants safer and more effective for patients without a matched donor.
- What could go wrong
- This is a small, early-phase trial (23 participants) testing a complex cell therapy. The treatment may not improve outcomes, and risks include infection, graft failure, or severe immune reactions.

Inclusion Criteria: * Patient who requires allogeneic hematopoietic stem cell transplant, has no human leukocyte antigen (HLA)-matched sibling donor but has an HLA-haploidentical donor. * Adequate organ function to tolerate the conditioning chemotherapy and radiotherapy * Karnofsky or Lansky performance status score ≥50 Exclusion Criteria: * Pregnant or lactating woman * HIV infection * Patients for whom alternative treatment is deemed more appropriate by treating physician * Patients who are unlikely to benefit from haploidentical hematopoietic stem cell transplantation, e.g., terminal malignancy with multiorgan failure
