GD2IL18CART Combined With Bevacizumab for Relapsed and Refractory GD2-positive Solid Tumors

This study will test a chimeric antigen receptor (CAR) T-cell treatment combined with bevacizumab in children and young adults with relapsed or refractory neuroblastoma, Ewing sarcoma, or osteosarcoma. The CAR T-cell treatment, called GD2IL18CART, is made from a patient's own T cells. The T cells are genetically modified to recognize GD2, a molecule found on the surface of these cancers, and to release the immune-stimulating protein interleukin-18 (IL-18) when they encounter tumor cells. Bevacizumab is an antibody that blocks vascular endothelial growth factor (VEGF), a protein that affects tumor blood vessels and may make it difficult for immune cells to enter tumors. Combining bevacizumab with GD2IL18CART may therefore help more CAR T cells reach the tumor and improve their antitumor activity. The main goals of this study are to determine whether the combination can be given safely, identify a recommended dose of GD2IL18CART for use with bevacizumab, and look for early evidence of antitumor activity. The study will also examine blood and tumor samples to better understand how the treatment affects CAR T cells and the tumor environment.

Effects of Maintenance Cabozantinib+BSC Versus BSC in Children and AYA With Osteosarcoma

The participants of this study will be children, adolescents, and young adults with residual osteosarcoma, which cannot be removed completely through surgery. Participants will have achieved a partial response or stable disease at the end of conventional chemotherapy. Osteosarcoma is cancer of the bone. The cancer cells make immature bone cells, known as osteoid. Osteosarcoma is very rare, but it is the most common type of bone cancer in children and teens. It is most common in teens and young adults. In this study, participants will receive either cabozantinib and best supportive care or the best supportive care alone. Best supportive care will be provided at the investigator's discretion and according to institutional guidelines. It includes antibiotics, nutritional support, correction of metabolic disorders, optimal symptom control and pain management (including radiotherapy), etc. but does not include tumor specific therapy. Cabozantinib will be taken by mouth (orally), as a tablet, once a day. Cabozantinib will be provided to participants who tolerate it for as long as their disease does not progress. Participants in the study receiving best supportive care alone may switch to treatment with cabozantinib and best supportive care if their disease progresses and if other eligibility criteria are met. Participants may withdraw consent to participate at any time. The estimated duration of the study for participants is 24 months, however a participant could remain in the study longer if demonstrating treatment benefit.

Fight Osteosarcoma Through European Research Evolving Study Platform From Diagnosis to Relapse

This clinical study is the initiative of the FOSTER (Fight OsteoSarcoma Through European Research) consortium and Gustave Roussy, which is the sponsor. Its aim is to evaluate the biology of tumour in greater depth by collecting samples of the tumour during the biopsy at diagnosis, and blood samples. This study is a platform study that evolves over time. This means that it allows for the evaluation of several treatments or therapeutic strategies within a single clinical trial, which can be modified and adapted over time. The FOSTER evolving study platform aim to implement a comprehensive strategy of clinical, biological, radiological, therapeutic integrated research from diagnosis to relapse, with the aim to improve survival of osteosarcoma patients of all age, through randomised therapeutic questions at different phase of treatment from diagnosis to relapse. The platform study makes it possible to evaluate several treatments for the same disease, on an ongoing basis, using a main protocol with adaptable arms. The FOSTER-CabOS trial (part 2 of FOSTER study) is a European Phase III clinical study . It assesses the efficacy of cabozantinib, a tyrosine kinase inhibitor, as a maintenance therapy post-standard treatment in osteosarcoma patients. The trial is randomized against Best Supportive Care to determine the effectiveness of cabozantinib in improving event-free survival. This maintenance therapy aims to prevent relapse among patients who have already received standard treatment for osteosarcoma.

EGFR806 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 EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR 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. The CD19 receptor harbors a different selection-suicide marker, HERtG. 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 subject's body on each arm. Subjects 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. Subjects 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.

A Phase I Feasibility And Safety Study of Fluorescein-Specific (FITC-E2) CAR T Cells In Combination With Parenterally Administered Folate-Fluorescein (UB-TT170) For Osteogenic Sarcoma

The purpose of this study is to see if a new treatment could help patients who have osteosarcoma that does not go away with treatment (is refractory) or comes back after treatment (is recurrent).This study is testing a combination of study therapies, UB-TT170 and genetically modified chimeric antigen receptor T lymphocyte (CAR T) cells, which work together in a way that is different from chemotherapy. In this study, researchers will take some of your blood and remove the T cells in a process called "apheresis". Then the T cells are taken to a lab and changed to CAR T cells that recognize the flags from UB-TT170. Once researchers think they have grown enough CAR T cells, called antiFL(FITC-E2) CAR T cells, to fight your cancer, you may get some chemotherapy to make room in your body for the new cells and then have those cells put back in your body. A few days after the you get your CAR T cell infusion you will start to get infusions of UB-TT170, with the dose slowly increasing for the first few infusions until you have reached a maximum dose that you will get on a regular schedule. The UB-TT170 will attach to your tumor cells and flag them so that they attract the CAR T cells. When the CAR T cells see the labeled tumor cells they can kill the tumor cells. The active part of the study lasts about 8 months, and if you get the CAR T cell infusion you will be in long-term follow-up for 15 years.
