This study is recruiting pediatric patients who have been diagnosed with osteosarcoma. Osteosarcoma is the most common primary bone malignancy of childhood and adolescence. The goal of the study is to determine the feasibility of adding cabozantinib to standard MAP (high dose methotrexate, doxorubicin, and cisplatin) chemotherapy in patients with newly diagnosed metastatic osteosarcoma with a resectable primary tumor and to compare the effects, good and/or bad, of cabozantinib in combination with MAP versus MAP alone on people with newly diagnosed OST to find out which is better. Common side effects of chemotherapy include nausea, vomiting, hair loss, and fatigue (tiredness). Participants will receive the medications through an IV in their arm and PO. Study participation is expected to last up to 16 months.

This study is recruiting pediatric patients who have been diagnosed with rhabdomyosarcoma (RMS). RMS is a type of cancer that occurs in the soft tissues of the body. The goal of the study is to compare the effects, good and/or bad, of giving less chemotherapy drugs to people with very low risk-RMS to find out which is better. Patients will be separated into two groups based on their tumor type: Low Risk and Very Low Risk. Participants in the Low Risk group will receive Vincristine, Dactinomycin and Cyclophosphamide. Participants in the Low Risk group will receive Vincristine and Dactinomycin. All participants will be tested for genetic differences (called MYOD1 and TP53). If any participant is found to have these genetic differences, they will receive Vincristine, Dactinomycin and Cyclophosphamide. Common side effects of chemotherapy include nausea, vomiting, hair loss, and fatigue (tiredness). Participants will receive the medications through an IV in their arm. Study participation is expected to last up to one year.

This study is for patients that have been diagnosed with high risk neuroblastoma. This study is testing an investigational drug called Dinutuximab, which will be combined with standard care induction and transplant. "Investigational" means it has not been approved by the United States Food and Drug Administration (FDA).
The primary purpose of this study is to compare treatment outcomes of participants who are assigned to early chemoimmunotherapy (Dinutuximab and Sargramostim) during Induction to treatment outcomes of participants who are not assigned to treatment that includes early chemoimmunotherapy. Participants will be randomized to the standard of care arm of the trial or the standard of care arm plus chemoimmunotherapy (like flipping a coin). The investigational drug is given to participants through IV infusion. Participants in this study can expect to be in this study for a total of five years.

This study is for patient that have been diagnosed with High Risk Neuroblastoma. The investigational drug in this study is naxitamab. The purpose of this study is to test the safety of adding an Anti-GD2 Immunotherapy agent (naxitamab) to your standard therapy during the induction phase of care. Read the sections on risks and benefits carefully and be sure you understand them. This study will also look at the effectiveness of this treatment.

This study is for patients that have been diagnosed with early-stage (Stage I or II) Hodgkin lymphoma (HL)(cHL). The main purpose of this study is to compare the effects, good and/or bad, of brentuximab vedotin and nivolumab (Bv-NIVO) against standard therapy for people with HL to find out which is better. Participants can expect to be in the study for up to 54 months.

This study is for patients that have been diagnosed with relapsed/refractory neuroblastoma. The investigational drug given is eflornithine (DFMO) along with etoposide. DFMO is the investigational drug being used along with etoposide for treatment of neuroblastoma. Participants will undergo a number of standard tests and research-related procedures before being able to enroll in this study. Some risks include but are not limited to: fewer red and white blood cells, diarrhea, abdominal pain, loss of appetite, skin rash, seizure, difficulty swallowing and blurred vision. Participants can expect to be on this study for approximately 2 years. Participants will then be followed for up to 5 years after study completion.

This study is for patients that have been diagnosed with leukemia. This study is called a screening study and we are doing this study to find better ways to diagnose and treat leukemia in children, adolescents and young adults. Bone marrow, blood, and medical information about participant's cancer and treatment will be collected. Participants can expect to be on this study for 5 years.

This study is for patients that have been diagnosed with non-germinomatous germ cell tumor (NGGCT). The goal of this study is to see if radiation therapy (RT) to the spine and a portion of the brain works just as well as the standard treatment, which includes RT to the whole brain and spine, for people with NGGCT who agree to take part in this study, and whose disease responds well to induction chemotherapy, or who have no signs of disease following surgery. Participants can expect to receive treatment on this study for about 6 to 11 months, depending on which therapy they receive. After study completion, participants will continue to be followed for up to 10 years.

This study is for newly diagnosed or previously untreated low-grade glioma (LGG). The overall goal of this study is to see if selumetinib works just as well as the standard treatment using carboplatin and vincristine (called CV) for subjects with LGG. Selumetinib is a drug that works by blocking a protein (a basic building block of the human body) that lets cancer cells grow without stopping. Participants can expect to receive treatment on this study for about 1–2 years. After study completion, participants will continue to be followed for up to 10 years.

This study is for participants that have been diagnosed with Medulloblastoma. The purpose of this study is to test the effectiveness of using an investigational agent called DFMO for Medulloblastoma. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This study will look at the ability of this study drug to either keep participants tumor in remission or if they have active tumor, for their tumor to respond to the treatment and will also look at the safety and tolerability of DFMO. After this first day participants will be seen in clinic once every 30 days for the first 6 months of the study, after that they will be seen once every 90 days for the remainder of the study. These visits will last about 2 hours.
