This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT03934372RecruitingPhase 1/Phase 2
Ponatinib for children with relapsed or hard-to-treat cancers
This trial tests a targeted therapy called ponatinib in children whose leukemia, lymphoma, or solid tumor has come back or hasn't improved with standard treatments. The drug works by blocking signals that help cancer cells grow, and the study looks at how safe and effective it is for different cancer types.
GhentAges 1–17 - NCT03970096RecruitingPhase 2
Reduce graft-versus-host disease after stem cell transplant
This Phase 2 study tests ways to lower the risk of graft-versus-host disease (GVHD), a serious complication after an allogeneic stem cell transplant from a matched donor.
