This study involves an investigational cellular therapy called Afamitresgene Autoleucel. The overall goal of this study is to find out how safe and effective this cellular therapy is in treating people that have been diagnosed with synovial sarcoma, malignant peripheral nerve sheath tumors (MPNST), neuroblastoma or osteosarcoma that has grown or returned after being treated.

The purpose of this study is to determine whether AUTO1, an experimental form of therapy, is safe and effective in helping the immune system fight cancer. AUTO1 uses immune cells, called T cells, that are collected from the blood using a process called leukapheresis and then modified in a lab to recognize and target cancer cells. These modified cells are then put back into the body through infusion.

This study enrolls patients between 5 and 40 years of age with a diagnosis of any sarcoma that has progressed on or relapsed after upfront initial therapy. The purpose of this study is to find the best dose of a drug called cabozantinib ("the study drug") to give to patients in combination with a routine chemotherapy drug called ifosfamide.

The purpose of this study is to test a cell therapy for T-Cell Lymphoblastic Leukemia or Lymphoma. The CAR T-cells are made by collecting T-cells from donors and modifying them to attach to cancer cells. CAR T-cells have been used to treat other cancers, but these cells, known as BEAM-201 cells, are an experimental treatment. The participants will be given BEAM-201 cells via an IV and then monitored for up to 12 months.

This study will assess the safety and effectiveness of BEAM-201 cells.

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 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 enrolls patients with refractory, progressive, or relapsed solid tumors. The purpose of this study is to find out whether a drug called PEEL-224 ("the study drug") is safe and effective when given as monotherapy (a drug given by itself) and as part of a combination therapy together with other chemotherapy drugs.

This study involves taking a study drug called CUDC-907. CUDC-907 is an oral drug that blocks certain proteins in tumor cells; these proteins may be important in the growth of some cancers. The overall goals of this study are to evaluate the side effects and benefits of CUDC-907 in patients with relapsed or treatment refractory solid tumor, brain tumor, or lymphoma, and to determine the best dose of CUDC-907 for children and adolescents. This study will also look at the levels of CUDC-907 in the blood over time after a dose.

CAR T cell therapy has shifted the treatment landscape for pediatric and young adult patients with advanced B-cell leukemias. However, the manufacturing process remains in its first generation: difficult, time-consuming, and not automated. The time and significant resources in this process can result in patient safety issues - with patients growing sicker, with harder to control leukemias - in the waiting period. Use of the CliniMACS Prodigy platform can help to surmount these issues. This study will determine the safety and usefulness of using the CliniMACS Prodigy platform to manufacture huCART19 cells.

This is a Phase 1/2b trial for the treatment of patients with either advanced or refractory B cell Acute Lymphoblastic Leukemia or B-lineage lymphoblastic lymphoma who will be treated with huCART19, which has been manufactured using the CliniMACs Prodigy Platform. Possible procedures include medical record review, apheresis, huCART19 infusion, blood draws, physical exams, imaging, and disease assessments through bone marrows and lumbar punctures. Overall, approximately 89 subjects will be enrolled on this clinical trial.

The purpose of this study is to test the safety and efficacy of the investigational drug called repotrectinib in children whose cancers have specific genetic changes (in the ALK, ROS1, or NTRK1-3 genes). This is the first study using this drug in children under 12 years of age. Repotrectinib is administered in capsule form or liquid suspension.
