Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

This phase II Pediatric MATCH 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.

This phase III trial compares the effect of selumetinib versus the standard of care treatment with carboplatin and vincristine (CV) in treating patients with newly diagnosed or previously untreated low-grade glioma (LGG) that does not have a genetic abnormality called BRAFV600E mutation and is not associated with systemic neurofibromatosis type 1. Selumetinib works by blocking some of the enzymes needed for cell growth and may kill tumor cells. Carboplatin and vincristine are chemotherapy drugs that work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. The overall goal of this study is to see if selumetinib works just as well as the standard treatment of CV for patients with LGG. Another goal of this study is to compare the effects of selumetinib versus CV in subjects with LGG to find out which is better. Additionally, this trial will also examine if treatment with selumetinib improves the quality of life for subjects who take it.

This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 positive lymphoma cells in a targeted way and delivers vedotin to kill them. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs such as doxorubicin hydrochloride, bleomycin sulfate, vinblastine sulfate, dacarbazine, and procarbazine hydrochloride work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cells deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the bodys immune response. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Adding immunotherapy to the standard treatment of chemotherapy with or without radiation may increase survival and/or fewer short-term or long-term side effects in patients with classical Hodgkin lymphoma compared to the standard treatment alone.

This phase III trial compares the effect of an accelerated schedule of bleomycin sulfate, etoposide phosphate, and cisplatin (BEP) chemotherapy to the standard schedule of BEP chemotherapy for the treatment of patients with intermediate or poor-risk germ cell tumors that have spread to other places in the body (metastatic). Drugs used in chemotherapy, such as bleomycin sulfate, etoposide phosphate, and cisplatin, 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 BEP chemotherapy on a faster, or accelerated schedule may work better with fewer side effects in treating patients with intermediate or poor-risk metastatic germ cell tumors compared to the standard schedule.

Difluoromethylornithine (DFMO) will be used in an open label, single agent, multicenter,
study for patients with neuroblastoma in remission. In this study subjects will receive 730
Days of oral difluoromethylornithine (DFMO) at a dose of 750 mg/m2 250 mg/m2 BID (strata 1,
2, 3, and 4) OR 2500 mg/m2 BID (stratum 1B) on each day of study. This study will focus on
the use of DFMO in high risk neuroblastoma patients that are in remission as a strategy to
prevent recurrence.

The purpose of this study is to evaluate two study medicines (encorafenib plus cetuximab)
taken alone or together with standard chemotherapy for the potential treatment of colorectal
cancer that:

- has spread to other parts of the body (metastatic);

- has a certain type of abnormal gene called "BRAF"; and

- has not received prior treatment.

Participants in this study will receive one of the following study treatments:

- Encorafenib plus cetuximab: These participants will receive encorafenib by mouth at home
every day and cetuximab once every two weeks by intravenous (IV) infusion (an injection
into the vein) at the study clinic.

- Encorafenib plus cetuximab with chemotherapy: These participants will receive
encorafenib and cetuximab in the way described in the bullet above. Additionally, they
will receive standard chemotherapy by IV infusion and oral treatment at home.

- Chemotherapy alone: These participants will receive chemotherapy, the standard treatment
for this condition, by IV infusion at the study clinics and oral treatment at home.

The study team will monitor how each participant responds to the study treatment for up to
about 3 years.

The purpose of this study is to determine the clinical benefit and characterize the safety
profile of tabelecleucel for the treatment of Epstein-Barr virus-associated post-transplant
lymphoproliferative disease (EBV+ PTLD) in the setting of (1) solid organ transplant (SOT)
after failure of rituximab and rituximab plus chemotherapy or (2) allogeneic hematopoietic
cell transplant (HCT) after failure of rituximab.

The objective of this study is to assess safety and efficacy of CAB-AXL-ADC in solid tumors
