Medulloblastoma recurrent

This study tests a combination of drugs given in low, frequent doses to slow or stop the growth of recurrent brain tumors in children. The goal is to extend survival while maintaining quality of life. About 232 children with medulloblastoma, ependymoma, ATRT, or other rare CNS tu…

This early-stage trial tests whether using focused ultrasound with microbubbles can temporarily open the blood-brain barrier, allowing the immunotherapy drug nivolumab to reach brain tumors more effectively. It includes 30 children and young adults with relapsed diffuse midline g…

This early-stage trial tests whether a specially engineered herpes virus (G207) is safe to inject directly into the brain tumors of children whose cancer has returned. Up to 24 children aged 3 to 21 will receive the virus, and some will also get a small dose of radiation to help …

This early-phase study tests the safety of a new cell therapy called B7-H3 CAR T cells for children and young adults whose brain tumors have come back or are growing despite standard treatment. The therapy uses the patient's own immune cells, modified to target a protein (B7-H3) …

This study tests a thyroid hormone called liothyronine (L-T3) alone or with standard chemotherapy in children and young adults whose medulloblastoma has come back or worsened. The goal is to see if adding L-T3 can help control the cancer better. About 69 participants will take pa…

This study is testing a combination of two drugs—a targeted radioactive drug (177Lu-DOTATATE) and a PARP inhibitor (olaparib)—in children and teens aged 3 to 18 with certain solid tumors that have come back or not responded to treatment. The goal is to see if the combination is s…

This early-phase trial is testing a combination of three treatments for children whose brain tumors have come back or not responded to standard care. The experimental drug SGT-53 delivers a normal TP53 gene to tumor cells, and is given alongside the immunotherapy Nivolumab and ra…

This study is building a biobank of blood, tissue, and health information from 300 children and adults with relapsed or hard-to-treat sonic hedgehog medulloblastoma, a type of brain tumor. Researchers want to learn more about a specific genetic mutation called U1, which may affec…

This study is testing a new approach for children and young adults whose medulloblastoma or ependymoma has come back. Researchers will analyze each person's tumor using drug screening and genetic testing to create a personalized treatment plan. The goal is to find the most effect…
