Selective Antigen Specific T Cells and CAR T Cells in Subjects With Relapsed/Refractory Embryonal Tumors (SABRE)

This is a phase I dose-escalation study to determine the safety and feasibility of autologous CAR-TA T cells (B7-H3 CAR+ T cells administered with DNR-PRAME Tumor Antigen-specific T cells) following lymphodepleting chemotherapy in participants with relapsed/refractory rhabdomyosarcoma, Ewing sarcoma, neuroblastoma and Wilms tumor. Patients will be enrolled to one of three planned dose levels with B7-H3 CAR T cell dose determined based on the percentage of B7-H3 transduced cells (B7-H3+ population of cells), and dTBRII-transduced PRAME TA-specific T cell dose based on the total cell population. Both doses will be based on the recipient's body weight. The safety of the CAR-TA T cell product will be evaluated and the maximum tolerated dose (MTD) will be determined. The safety endpoint will be assessed by monitoring for dose limiting toxicities for 28 days following CAR-TA T cell administration.

Biologically-Adapted, Dose-Escalated Radiotherapy for the Treatment of Ewing Sarcoma, BEAR Trial

This clinical trial evaluates the effect of radiotherapy doses based on tumor size and tumor-specific characteristics (biologically-adapted) in treating patients with Ewing sarcoma. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Conventional radiotherapy uses minimal imaging support to determine the positioning of radiotherapy. Hypofractionated radiotherapy delivers higher doses of radiotherapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Dose-escalated radiotherapy uses doses that are higher than those used in conventional radiotherapy. Larger tumor sizes and other tumor-specific characteristics have been shown to be related to poorer outcomes. In addition, after dose-escalated radiotherapy, patients with larger tumors have demonstrated improved control of the disease at the primary tumor site. Giving biologically-adapted, dose-escalated radiotherapy may reduce the return of the cancer at the primary tumor site in patients with Ewing sarcoma with large tumors and other unfavorable characteristics. This clinical trial also evaluates the role of biomarkers in patients with Ewing sarcoma. Studying samples of blood and tumor tissue from patients with Ewing sarcoma in the laboratory may help doctors learn more about predicting the amount of disease and the likelihood of the cancer coming back.

Personalized Vaccination in Fusion+ Sarcoma Patients (PerVision)

The PerVision trial utilizes an approach of a patient-individual cancer vaccine with sarcoma-specific peptides in metastasized fusion-driven sarcoma patients determined by next generation whole exome sequencing of tumor and normal tissue as well as RNA sequencing of the tumor. This approach is applicable to all patients independent of the expression of distinct tumor associated antigens, and independent of their human leukocyte antigen-typing (HLA-typing). The results of this study can directly be translated to other tumor entities. It is an interventional, multicenter, open-label, phase I/II feasibility and early proof of concept study evaluating a personalized peptide vaccine. Primary objective is to evaluate safety and success of treatment, the latter be defined as vaccination-induced T-cell response without unacceptable toxicity.

B7H3 CAR T Cell Immunotherapy for Recurrent/Refractory Solid Tumors in Children and Young Adults

This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a B7H3-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express B7H3. On Arm A of the study, research participants will receive B7H3-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at B7H3 and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. Arm A CAR T cells include the protein EGFRt and Arm B CAR T cells include the protein HER2tG. These proteins can be used to both track and destroy the CAR T cells in case of undue toxicity. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the participant's body on each arm. Participants will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Participants who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.

Methionine PET/CT Studies In Patients With Cancer

The purpose of this study is to test the usefulness of imaging with radiolabeled methionine in the evaluation of children and young adults with tumor(s). Methionine is a naturally occurring essential amino acid. It is crucial for the formation of proteins. When labeled with carbon-11 (C-11), a radioactive isotope of the naturally occurring carbon-12, the distribution of methionine can be determined noninvasively using a PET (positron emission tomography) camera. C-11 methionine (MET) has been shown valuable in the monitoring of a large number of neoplasms. Since C-11 has a short half life (20 minutes), MET must be produced in a facility very close to its intended use. Thus, it is not widely available and is produced only at select institutions with access to a cyclotron and PET chemistry facility. With the new availability of short lived tracers produced by its PET chemistry unit, St. Jude Children's Research Hospital (St. Jude) is one of only a few facilities with the capabilities and interests to evaluate the utility of PET scanning in the detection of tumors, evaluation of response to therapy, and distinction of residual tumor from scar tissue in patients who have completed therapy. The investigators propose to examine the biodistribution of MET in patients with malignant solid neoplasms, with emphasis on central nervous system (CNS) tumors and sarcomas. This project introduces a new diagnostic test for the noninvasive evaluation of neoplasms in pediatric oncology. Although not the primary purpose of this proposal, the investigators anticipate that MET studies will provide useful clinical information for the management of patients with malignant neoplasms.

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.
