Can tailored drug dosing make stem cell transplants safer?
NCT ID NCT07791576
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
This trial tests whether giving anti-thymocyte globulin (ATG) at a dose tailored to each patient's body can improve outcomes after a half-matched stem cell transplant. ATG is used to prevent graft-versus-host disease, a serious complication where donor cells attack the patient's body. Researchers will compare the standard dosing approach with a personalized one based on a pharmacokinetic formula. The main goal is to see if the tailored approach improves survival without severe graft-versus-host disease or relapse within the first year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Anti-thymocyte globulin (ATG), a drug that suppresses the immune system to prevent graft-versus-host disease, given at a dose tailored to each patient using a pharmacokinetic formula.
- What this could lead to
- If this works, it could reduce severe complications like graft-versus-host disease and relapse after stem cell transplants, improving survival and quality of life for patients with blood cancers.
- What could go wrong
- This is a Phase 2 trial with 63 participants, so results are preliminary. The personalized dosing may not improve outcomes, and ATG can increase infection risk, including viral reactivation.

Inclusion Criteria: 1. Patients with indications for allogeneic hematopoietic stem cell transplantation, with malignant hematologic diseases in CR1 or CR2 before transplantation. 2. Have an HLA-matched sibling, unrelated, or haploidentical donor. 3. Age ≥ 14 years and ≤ 65 years. 4. Liver function: ALT and AST ≤ 2.5 × upper limit of normal, bilirubin ≤ 2 × upper limit of normal. 5. Renal function: creatinine ≤ upper limit of normal. 6. No uncontrolled infection or severe mental or psychological disorders. 7. ECOG performance status score of 0-2. 8. Signed informed consent. Exclusion Criteria: 1. No HLA-matched donor. 2. Malignant hematologic disease in CR3 or higher disease stage, or refractory/relapsed status,or second transplantation. 3. Patient age \< 14 years or \> 65 years. 4.
