The goal is to prepare the body for the transplant while killing remaining cancer cells more precisely.
Duarte, CaliforniaAges 18–70 - NCT03779854RecruitingPhase 2
Preventing graft-versus-host disease in kids after stem cell transplant
This trial tests whether removing certain immune cells (T cells) from the donor transplant can lower the risk of chronic graft-versus-host disease (long-term immune attack after transplant) in children and young adults with blood cancers. If you qualify, it may help improve transplant outcomes while tracking safety and side effects.
Los Angeles, CaliforniaAges 6 months–26 years - NCT03126916RecruitingPhase 3
Testing added therapy for high-risk neuroblastoma in children
This Phase 3 study tests whether adding either a targeted drug (lorlatinib) or a radioactive treatment (131I-MIBG) to intensive chemotherapy improves outcomes for children with high-risk neuroblastoma. It may help by aiming at tumor cells more directly alongside standard treatment.
Downey, CaliforniaAges 12 months–30 years - NCT03279094RecruitingPhase 1
Testing a half-matched bone marrow transplant for sickle cell
This early-phase study tests whether a “half-matched” donor bone marrow transplant, with special medicines to calm the immune system before transplant, can improve outcomes for people with sickle cell disease. It may help high-risk patients who have frequent complications and don’t have a fully matched donor.
Duarte, CaliforniaAges 1–30 - NCT03394365RecruitingPhase 3
Tabelecleucel for EBV-related lymphoma after transplant treatment failure
This trial tests tabelecleucel, an immune therapy, for people whose EBV-associated post-transplant lymphoproliferative disease (PTLD) did not respond to rituximab and/or chemotherapy. It may help your immune system better control EBV-driven lymphoma after a transplant.
Duarte, CaliforniaAges Any age - NCT04047628RecruitingPhase 3
MS patients with active relapsing disease comparing two treatment plans

What taking part in a hematopoietic stem cell transplant study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
