This study tests a drug called nirogacestat in children and teens with desmoid tumors that have grown despite treatment and cannot be surgically removed. The goal is to see if the drug can stop or slow tumor growth and to check for side effects. About 31 participants aged 1 to 18…

This phase III trial tests a combination of arsenic trioxide and tretinoin (a vitamin A derivative) in 158 people with newly diagnosed acute promyelocytic leukemia (APL). The goal is to see if this drug pair can replace high-dose anthracycline chemotherapy, which can cause long-t…

This study tests whether adding eflornithine (DFMO) to a standard chemotherapy and immunotherapy regimen can improve outcomes for children with neuroblastoma that has returned or is not responding to treatment. About 94 children will be randomly assigned to receive the standard t…

This study looks at a drug called enasidenib for children and teens with acute myeloid leukemia (AML) that has come back or is hard to treat. The drug targets a specific genetic change (IDH2 mutation) found in their cancer cells. The main goals are to check the drug's safety and …

This study tests different combinations of chemotherapy drugs, along with surgery, for children and young adults with two types of liver cancer: hepatoblastoma and hepatocellular carcinoma. The goal is to see which combinations work best to stop tumor growth and improve survival.…

This study tests a drug called larotrectinib in children and young adults (up to age 30) with certain cancers that have a specific genetic change called a TRK fusion. The goal is to see if the drug can shrink solid tumors or control leukemia that has returned. The drug works by b…

This study tests whether adding two chemotherapy drugs (irinotecan and temozolomide) to the standard immunotherapy regimen (dinutuximab, GM-CSF, isotretinoin) can safely prevent high-risk neuroblastoma from returning after intensive initial therapy. About 41 children and young ad…

This study tests the drug bosutinib in 60 children with Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML). Some children are newly diagnosed, while others have not responded to or cannot tolerate other treatments. The goal is to find the best dose and see if the…

This study tests whether a probiotic called Lactobacillus plantarum can prevent a serious complication called graft-versus-host disease (GvHD) in the gut of children receiving a donor stem cell transplant. About 173 children with blood cancers or other conditions are taking the p…

This study tests whether adding levocarnitine, a natural nutrient, to standard chemotherapy can prevent severe liver damage in teens and young adults (ages 15-39) with leukemia or lymphoma. About 440 participants will receive either chemotherapy alone or chemotherapy plus levocar…

This study tests whether memantine, a drug used for Alzheimer's, can protect memory and thinking in children aged 4-17 receiving brain radiation for central nervous system tumors. About 192 participants will receive either memantine or a placebo during and after radiation. The go…

This study follows 549 children, teens, and young adults with cancer to see how their immune systems respond to COVID-19 vaccines. Researchers collect blood samples to measure protective antibodies. The goal is to learn how cancer and its treatment affect vaccine effectiveness, a…
