Integration of Adaptive Proton Therapy in Pediatric Solid Tumors and Hodgkin's Lymphoma

Pediatric patients receiving proton therapy for solid tumors or Hodgkin's lymphoma may experience anatomical changes during treatment that can affect proton therapy accuracy. This prospective single-arm study uses regular low-dose imaging to monitor these changes and adjust treatment plans as needed. Participants will receive weekly or every-other-week CT scans, with MRI when appropriate, to assess whether the original plan remains accurate. Treatment plans will be updated if tumor coverage decreases by more than 5% or if radiation dose to normal tissues increases by more than 10%; otherwise, the original plan will continue. The study aims to determine how often plan adjustments are needed and to identify which disease sites are most likely to experience significant anatomical changes during treatment. Primary Objective: * Define the frequency of replanning necessary to ensure tumor coverage never falls below 95% (or 5% drop) of the prescribed daily dose in participants with intact (gross) tumors to keep the tumor control optimal throughout the multi-week treatment regimen. * Define the frequency of replanning necessary to ensure organs-at-risk (critical organs) do not deviate by more than 10% of the initially approved dose constraints to keep the normal tissue complication minimal throughout the multi-week treatment regimen. Secondary Objectives * Establish a cone beam CT (CBCT)-based framework for quantifying body surface changes throughout the treatment course. This goal will be achieved by developing a novel algorithm that detects and tracks external anatomical variations longitudinally, without requiring CBCT image enhancement, enabling precise assessment of daily participant setup consistency and anatomical stability. * Overcome daily CBCT quality limitations by generating synthetic CT images that accurately represent daily anatomy and support proton dose recalculation or verification planning. This goal will be achieved by developing a hybrid pipeline that integrates deep learning models with the deformable image registration algorithm, trained and validated on disease site-specific data. This will enable precise dose mapping and tissue density estimation, directly supporting adaptive planning decisions without the need of diagnostic- quality CT images.

Alpha/Beta T and B Cell Depletion With Zoledronic Acid for Solid Tumors

Hematopoietic stem cell transplantation can cure patients with blood cancer and other underlying diseases. αβ-T cell and B cell depletion has been introduced to decrease GVHD and PTLD and has demonstrated effectiveness for hematologic malignancies and non-malignant diseases additionally increasing the donor pool as to allow for haploidentical transplant to safely occur. While solid tumors can be highly chemotherapy sensitive, many remain resistant and require multimodalities of treatment. Immunotherapy has been developed to harness the immune system in fighting solid tumors, though not all have targeted effects. Some solid tumors are treated with autologous transplants; however, they do not always demonstrate an improved event free survival or overall survival. There has been evidence of the use of allogeneic stem cell transplants to provide a graft versus tumor effect, though studies remain limited. By utilizing αβ-T cell and B cell depletion for stem cell transplants and combining with zoledronic acid, the immune system may potentially be harnessed and enhanced to provide an improved graft versus tumor effect in relapsed/refractory solid tumors and promote an improved event-free survival and overall survival. This study will investigate the safety of treatment with a stem cell graft depleted of αβ-T cell and CD19+ B cells in combination with zoledronic acid in pediatric and young adult patients with select solid tumors, as well as whether this treatment improves survival rates in these patients.

Familial Investigations of Childhood Cancer Predisposition

NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: * Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: * Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.

Interleukin-15 and -21 Armored Glypican-3-specific Chimeric Antigen Receptor Expressed in T Cells for Pediatric Solid Tumors

Patients may be considered if the cancer has come back, has not gone away after standard treatment or the patient cannot receive standard treatment. This research study uses special immune system cells called CARE T cells, a new experimental treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. Investigators have found from previous research that they can put a new gene (a tiny part of what makes-up DNA and carries a person's traits) into T cells that will make them recognize cancer cells and kill them. In the lab, investigators made several genes called a chimeric antigen receptor (CAR), from an antibody called GPC3. The antibody GPC3 recognizes a protein found solid tumors including pediatric liver cancers. This CAR is called GPC3-CAR. To make this CAR more effective, investigators also added two genes that includes IL15 and IL21, which are protein that helps CAR T cells grow better and stay in the blood longer so that they may kill tumors better. The mixture of GPC3-CAR and IL15 plus IL21 killed tumor cells better in the laboratory when compared with CAR T cells that did not have IL15 plus IL21 .This study will test T cells that investigators made (called genetic engineering) with GPC3-CAR and the IL15 plus IL21 (CARE T cells) in patients with GPC3-positive solid tumors. T cells made to carry a gene called iCasp9 can be killed when they encounter a specific drug called AP1903. The investigators will insert the iCasp9 and IL15 plus IL21 together into the T cells using a virus that has been made for this study. The drug (AP1903) is an experimental drug that has been tested in humans with no bad side-effects. The investigators will use this drug to kill the T cells if necessary due to side effects. This study will test T cells genetically engineered with a GPC3-CAR and IL15 plus IL21 (CARE T cells) in patients with GPC3-positive solid tumors. The CARE T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of CARE T cells that is safe, to see how long they last in the body, to learn what the side effects are and to see if the CARE T cells will help people with GPC3-positive solid tumors.

FGFR4 Chimeric Antigen Receptor (CAR) T Cells in Children and Young Adults With Recurrent or Refractory Rhabdomyosarcoma

Background: Rhabdomyosarcoma (RMS) is a cancer of soft tissues. It is the most common soft tissue sarcoma seen in children. RMS cancer cells have a protein called FGFR4 on their surface. Researchers want to try a new kind of treatment for RMS: They will collect a person s own T cells, a type of immune cell; then they will change the T cells so they are better able to target the FGFR4 protein and attack RMS tumor cells. The modified T cells are chimeric antigen receptor (CAR) T cells. The treatment in this study is called FGFR4-CAR T cells. Objective: To test FGFR4-CAR T cells in children and young adults with RMS. Eligibility: People aged 3 to 39 years with RMS. The RMS must have failed to respond or returned after at least 2 rounds of standard treatment. Design: Participants will be screened. They will have physical exam, imaging scans, blood tests, and tests of their heart. They may have a tissue sample taken from their tumor. They will undergo apheresis: Blood will be taken from the body through a catheter. The blood will pass through a machine that separates out the T cells, and the remaining blood will be returned to the body. The collected T cells will be taken to a lab to create FGFR4-CAR T cells. Once the FGFR4-CART cells are ready, participants can receive these T cells. For 4 days they will receive drugs to prepare their body for the FGFR4-CAR T cells. After this, the modified T cells will be infused into a vein. Participants will be then monitored closely to watch for any side effects from the CART cells and be followed to see what effect the CART cells have on their tumors. They will have follow-up visits for up to 5 years. Long-term follow-up will be another 10 years.

A Study Comparing Higher Dose Chemotherapy Over a Shorter Amount of Time to Lower Dose Chemotherapy Plus Maintenance Over a Longer Amount of Time in Patients With Newly Diagnosed Intermediate-Risk Rhabdomyosarcoma (IR RMS)

This phase III trial compares higher dose chemotherapy, with vincristine, dactinomycin and cyclophosphamide, over a shorter amount of time to lower dose chemotherapy plus maintenance, with vincristine, dactinomycin, cyclophosphamide, irinotecan and vinorelbine, over a longer amount of time, along with standard of care surgery and radiation, in patients with newly diagnosed intermediate risk rhabdomyosarcoma. Vincristine and vinorelbine are in a class of medications called vinca alkaloids. They work by stopping tumor cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy (antineoplastic antibiotic). It works by damaging the cell's DNA and may kill tumor cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells. It may also lower the body's immune response. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. It is not yet known if the higher dose chemotherapy over a shorter amount of time or the lower dose chemotherapy with maintenance over a longer amount of time is more effective in the treatment of patient with newly diagnosed, intermediate risk rhabdomyosarcoma.

HER2 Chimeric Antigen Receptor (CAR) T Cells in Combination With Checkpoint Blockade in Patients With Advanced Sarcoma

The purpose of this study is to learn whether it is safe to give HER2-CAR T cells in combination with an immune checkpoint inhibitor drug (pembrolizumab or nivolumab), to learn what the side effects are, and to see whether this therapy might help patients with sarcoma. Another goal of this study is to study the bacteria found in the stool of patients with sarcoma who are being treated with HER2 CAR T cells and immune checkpoint inhibitor drugs to see if the types of bacteria influence how well the treatment works. The investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. They now want to see if they can put a new gene in these cells that will let the T cells recognize and kill sarcoma cells. The new gene that the investigators will put in makes an antibody specific for HER2 (Human Epidermal Growth Factor Receptor 2) that binds to sarcoma cells. In addition, it contains CD28, which stimulated T cells and make them last longer. After this new gene is put into the T cell, the T cell becomes known as a chimeric antigen receptor T cell or CAR T cell. In another clinical study using these CAR T cells targeting HER2 as well as other studies using CAR T cells, investigators found that giving chemotherapy before the T cell infusion can improve the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of the patient's lymphocytes first should allow the infused T cells to expand in the body, and potentially kill cancer cells more effectively. The chemotherapy used for lymphodepletion is a combination of cyclophosphamide and fludarabine. After the patient receives the lymphodepletion chemotherapy and CAR T cells during treatment on the study, they will receive an antibody drug called an immune checkpoint inhibitor, pembrolizumab or nivolumab. Immune checkpoint inhibitors are drugs that remove the brakes on the immune system to allow it to act against cancer.

Cytokine Armored GPC3 Specific Chimeric Antigen Receptor Expressing T-cells in Adults With Solid Tumors

This Phase 1, open-label, non-randomized study will enroll adult subjects with relapsed or refractory non-central nervous system (CNS) malignant solid tumors expressing glypican-3 (GPC3) to examine the safety, feasibility, and efficacy of administering T cell products derived from peripheral blood mononuclear cells (PBMC) that have been genetically modified to co-express a GPC3-specific chimeric antigen receptor (CAR), interleukin (IL)-15 and IL-21 as well as the inducible caspase 9 (iC9) suicide gene (SC-CAR.GPC3xIL15.21 T cells). An adult participant meeting all eligibility criteria and meeting none of the exclusion criteria will have a blood sample collected, which will be used to bioengineer the CAR T cells targeting their tumor.
