Niclosamide for children and young adults with difficult leukemia
This Phase 1 study tests niclosamide, a medicine being studied as a new treatment, for pediatric and young adult AML that has come back or did not respond. It mainly focuses on whether the drug can be given safely and what dose might work best.
Palo Alto, CaliforniaAges 2–25 - NCT06265545Recruiting
Study for relapsed or hard-to-treat AML
This trial tests new treatment options for people whose acute myeloid leukemia (AML) has either not responded to standard therapy or returned. It aims to find better ways to help those who need new options.
TianjinAges Any age - NCT05024552RecruitingPhase 1
Vyxeos plus gilteritinib for certain relapsed AML
This Phase 1 trial studies whether combining Vyxeos (a chemotherapy) with gilteritinib (a targeted drug) can treat AML that has come back or hasn’t responded well, specifically AML with certain FLT3 mutations. If it works, it could improve chances of controlling the leukemia.

Clayton, VictoriaAges Up to 17 years - NCT04016129RecruitingPhase 1/Phase 2
CAR-T therapy for certain B-cell blood cancers
This trial tests a lab-made immune therapy called CAR-T that targets specific markers on B-cell leukemia/lymphoma cells. It may help people whose cancer has returned or did not respond after earlier CD19 CAR-T, by attacking the cancer cells using added targeting.
Shenzhen, GuangdongAges 6 months–75 years - NCT04318678RecruitingPhase 1
CD123 CAR T-cell therapy for relapsed leukemia and related cancers
This early-phase study tests a lab-made immune therapy (CD123 CAR T cells) for children and young adults up to age 21 whose cancer has come back or didn’t respond to treatment. The goal is to see if these CAR T cells can find and attack cancer cells that carry a marker called CD123.
Memphis, TennesseeAges Up to 21 years - NCT05257018RecruitingPhase 2
Chemo plus medicine in the spine to prevent lymphoma brain relapse
This Phase 2 study tests whether adding intrathecal methotrexate (a cancer drug delivered into the spinal fluid) to standard chemo can lower the risk of diffuse large B-cell lymphoma (DLBCL) coming back in the brain or spinal fluid. It is for people with higher-than-usual risk of central nervous system (CNS) relapse.
