Medulloblastoma clinical trials at UCLA

This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.

This phase II Pediatric MATCH trial studies how well samotolisib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with TSC or PI3K/MTOR mutations that have spread to other places in the body (metastatic) and have come back (recurrent) or do not respond to treatment (refractory). Samotolisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This randomized phase III trial studies different chemotherapy and radiation therapy regimens to compare how well they work in treating young patients with newly diagnosed, previously untreated, high-risk medulloblastoma. Drugs used in chemotherapy, such as vincristine sulfate, cisplatin, cyclophosphamide, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Carboplatin may make tumor cells more sensitive to radiation therapy. It is not yet known which chemotherapy and radiation therapy regimen is more effective in treating brain tumors.

This phase II Pediatric MATCH trial studies how well ivosidenib works in treating patients with solid tumors that have spread to other places in the body (advanced), lymphoma, or histiocytic disorders that have IDH1 genetic alterations (mutations). Ivosidenib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway called the IDH pathway.

This phase II Pediatric MATCH trial studies how well palbociclib works in treating patients with Rb positive solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with activating alterations (mutations) in cell cycle genes that have spread to other places in the body and have come back or do not respond to treatment. Palbociclib may stop the growth of cancer cells by blocking some of the proteins needed for cell growth.

This phase II pediatric MATCH treatment trial studies how well selpercatinib works in treating patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.

This phase II Pediatric MATCH trial studies how well tazemetostat works in treating patients with brain tumors, solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have come back (relapsed) or do not respond to treatment (refractory) and have EZH2, SMARCB1, or SMARCA4 gene mutations. Tazemetostat may stop the growth of tumor cells by blocking EZH2 and its relation to some of the pathways needed for cell proliferation.

This phase II pediatric MATCH trial studies how well tipifarnib works in treating patients with solid tumors that have recurred or spread to other places in the body (advanced), lymphoma, or histiocytic disorders, that have a genetic alteration in the gene HRAS. Tipifarnib may block the growth of cancer cells that have specific genetic changes in a gene called HRAS and may reduce tumor size.

This phase II Pediatric MATCH trial studies how well ulixertinib works in treating patients with solid tumors that have spread to other places in the body (advanced), non-Hodgkin lymphoma, or histiocytic disorders that have a genetic alteration (mutation) in a signaling pathway called MAPK. A signaling pathway consists of a group of molecules in a cell that control one or more cell functions. Genes in the MAPK pathway are frequently mutated in many types of cancers. Ulixertinib may stop the growth of cancer cells that have mutations in the MAPK pathway.
