A Study With Tovorafenib (DAY101) as a Treatment Option for Progressive, Relapsed, or Refractory Langerhans Cell Histiocytosis

This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form tumors in certain tissues and organs including bones, skin, lungs and pituitary gland and can damage them. This tumor is more common in children and young adults. DAY101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Using DAY101 may be effective in treating patients with relapsed or refractory Langerhans cell histiocytosis.

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.

Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders (The Pediatric MATCH Screening Trial)

This phase II Pediatric MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

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.

Q702 for the Treatment of Patients With Hematologic Malignancies

This phase I trial tests the safety, side effects, and best dose of Q702 in treating patients with hematologic malignancies. Q702 is in a class of medications called immunomodulatory agents. It works by helping the immune system kill cancer cells and by helping the bone marrow to produce normal blood cells. Giving Q702 may be safe, tolerable and/or effective in treating patients with hematologic malignancies.
