NCT02359565

Pembrolizumab in Treating Younger Patients With Recurrent, Progressive, or Refractory High-Grade Gliomas, Diffuse Intrinsic Pontine Gliomas, Hypermutated Brain Tumors, Ependymoma or Medulloblastoma

This phase I trial studies the side effects and best dose of pembrolizumab and to see how well it works in treating younger patients with high-grade gliomas (brain tumors that are generally expected to be fast growing and aggressive), diffuse intrinsic pontine gliomas (brain stem tumors), brain tumors with a high number of genetic mutations, ependymoma or medulloblastoma that have come back (recurrent), progressed, or have not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may induce changes in the body's immune system, and may interfere with the ability of tumor cells to grow and spread.

Ensartinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With ALK or ROS1 Genomic Alterations (A Pediatric MATCH Treatment Trial)

This phase II Pediatric MATCH treatment trial studies how well ensartinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with ALK or ROS1 genomic alterations that have come back (recurrent) or does not respond to treatment (refractory) and may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Ulixertinib in Treating Patients With Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With MAPK Pathway Mutations (A Pediatric MATCH Treatment Trial)

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.

Erdafitinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With FGFR Mutations (A Pediatric MATCH Treatment Trial)

This phase II Pediatric MATCH trial studies how well erdafitinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with FGFR mutations that have spread to other places in the body and have come back or do not respond to treatment. Erdafitinib may stop the growth of cancer cells with FGFR mutations by blocking some of the enzymes needed for cell growth.

Ivosidenib in Treating Patients With Advanced Solid Tumors, Lymphoma, or Histiocytic Disorders With IDH1 Mutations (A Pediatric MATCH Treatment Trial)

This phase II Pediatric MATCH trial studies how well ivosidenib works in treating patients with solid tumors, including central nervous system tumors, lymphomas and histiocytic disorders that have not responded to (refractory) or have come back after (recurrent) prior treatment that have IDH (isocitrate dehydrogenase) 1 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.

Tipifarnib for the Treatment of Advanced Solid Tumors, Lymphoma, or Histiocytic Disorders With HRAS Gene Alterations, a Pediatric MATCH Treatment Trial

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.

Selpercatinib for the Treatment of Advanced Solid Tumors, Lymphomas, or Histiocytic Disorders With Activating RET Gene Alterations, a Pediatric MATCH Treatment Trial

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.

Larotrectinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With NTRK Fusions (A Pediatric MATCH Treatment Trial)

This phase II Pediatric MATCH trial studies how well larotrectinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with NTRK fusions that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and have come back (relapased) or does not respond to treatment (refractory). Larotrectinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
