This study enrolls patients that have been diagnosed with osteosarcoma or neuroblastoma that has come back (relapsed) or has not responded to standard treatments (refractory). This study involves an investigational cellular therapy called GD2CART. The study will be testing different doses of the study drug to find the safest dose.

Children (less than 10 years of age) are eligible if they have been diagnosed with either a medulloblastoma tumor or CNS embryonal tumors of the brain or spinal cord. The standard approach to the treatment of these brain tumors in young children may include surgery, radiation therapy to the brain and spinal cord and chemotherapy. Radiation therapy is the use of high energy x-rays to kill cancer cells. Chemotherapy means treatment with cancer killing drugs. This research study will compare two different treatment regimens to see which is better for treating children with this type of brain cancer.

This study involves taking a study drug called INBRX-109. The overall goal of the study is to find out how safe and effective the study drug is in treating people that have been diagnosed with advanced or metastatic Ewing sarcoma or SDH-deficient solid tumor/Gastrointestinal Stromal Tumor (GIST).

This study enrolls patients with newly diagnosed differentiated thyroid cancer (papillary thyroid cancer or follicular thyroid cancer) that has spread to the lungs and has a genetic mutation called and NTRK fusion. The study involves taking a study drug called larotrectinib for approximately 6 months prior to receiving radioiodine therapy (RAI). The overall goal of this study is to find out if taking the study drug before RAI works better than receiving RAI alone (the usual standard of care treatment).

This study involves taking a study drug called lurbinectedin. The overall goal of this study is to see if different doses of lurbinectedin are safe and effective at treating children and young adults with recurrent or relapsed solid tumors, including Ewing Sarcoma.

This study involves taking a study drug called Lutathera. The overall goal of this study is to see if Lutathera is safe in adolescent subjects with either a gastroenteropancreatic neuroendocrine tumor (GEP-NET), or a pheochromocytoma and/or paraganglioma (PPGL). This study will also look at the levels of radioactivity after Lutathera administration.

This study enrolls patients with cancer diagnoses who are expected to be hospitalized (inpatient) for at least 21 days. The purpose of this study is to determine whether a 21 day individualized massage therapy intervention, when compared to a control group, is associated with improved sleep and more robust circadian rhythms.

This is a clinical trial for patients with neuroblastoma that has returned (relapsed) or has not responded to standard treatment. The patients will have a biopsy of their tumor that will be tested for genetic changes and then matched to available drugs. If the results from the testing show molecular features in the tumor that allow for study treatment, patients will be invited for further testing to see if they are eligible for new treatments. Experimental therapies are all taken orally and may consist of one drug or a combination of drugs

In this study we are seeking to learn how different eye tests and devices can help understand vision in patients with NF1, including how vision loss might show up on different eye imaging devices that measure the nerves or the blood vessels of the eye. The study aims to understand the mechanisms of vision loss caused by neurofibromatosis type 1 (NF1)-associated optic pathway gliomas, or NF1-OPGs. Subjects eight years and older with NF1 are eligible to enroll.
Subjects may not benefit directly from participating in this study, but the knowledge gained will help doctors understand the potential benefit of using these tests and other procedures to improve their ability to identify the best tests to monitor visual function, and ultimately identify treatments to improve vision, in children and adults with NF1.

The goal of this observational study is to describe the safety and effectiveness of larotrectinib in patients with locally advanced or metastatic TRK fusion cancer for whom a decision to treat with larotrectinib has been made before enrollment. This study will enroll participants with any tumors harboring the NTRK gene fusion including Soft Tissue Sarcomas, Central Nervous System, Melanoma, and Thyroid cancers.
