CD19 CAR T-cell therapy for tough B-cell blood cancers
This Phase 2 study tests a one-time CAR T-cell treatment aimed at CD19, a target found on many B-cell leukemias and lymphomas. It’s for people whose disease has come back or hasn’t responded to prior treatments, or who can’t have a stem cell transplant.
SingaporeAges birth–70 years - NCT05658640RecruitingPhase 1/Phase 2
Testing trametinib and steroid plus chemo for relapsed blood cancers
This early-phase trial tests whether adding trametinib and dexamethasone to standard chemotherapy can improve outcomes for children whose blood cancer has come back or did not respond. Because it is a Phase 1/2 study, the main goal is to see safety and learn the best way to treat your specific cancer type.
ViennaAges 1–21 - NCT05674175RecruitingPhase 1/Phase 2
Test two engineered immune cell treatments for B-cell leukemia
This trial tests a combination of two different engineered immune cell therapies to treat B-ALL (a leukemia). It’s designed for young people whose disease has come back, is hard to treat, or didn’t respond well to similar cell therapies.
