Active clinical trials for "Neuroblastoma"

Background: Autologous T cells engineered to express a T cell receptor (TCR) targeting NY-ESO-1 will be infused back to patients with NY-ESO-1- expressing malignancies. The patients pretreated with a lymphodepleting preconditioning regimen will be monitored after infusion of anti-NY-ESO-1 TCR-transduced T cells for adverse events, persistence of anti-NY-ESO-1 TCR-transduced T cells and treatment efficacy. Objectives: To evaluate the safety and the efficacy of anti-NY-ESO-1 TCR-transduced T cell-based immunotherapy for patients with NY-ESO-1- expressing malignancies. Eligibility: Patients older than one year of age, who have relapsed or refractory malignancies that express both NY-ESO-1 and human leukocyte antigen (HLA)-A2 molecules. Patients must have adequate organ functions. Design: Peripheral blood from patients will be collected for isolation of peripheral blood mononuclear cells (PBMCs), which will be transduced with a lentiviral or retroviral vector encoding an HLA-A2 restricted anti-NY-ESO-1 TCR gene. Patients will receive a lymphodepleting preconditioning regimen to prepare their immune system to accept modified T cells. Patients will receive an infusion of their own modified T cells. They will remain in the hospital to be monitored for adverse events until they have recovered from the treatment. Patients will have frequent follow-up visits to monitor the persistence of modified T cells and efficacy of the treatment.

The main aim of this clinical trial is to find a way of giving ch14.18/CHO, in combination with subcutaneous aldesleukin (IL-2) and oral isotretinoin (13-cis-RA), to children and young people with primary refractory or relapsed neuroblastoma without intravenous morphine.

To date, no curative option exists for patients with relapsed or refractory stage IV neuroblastoma after previous autologous stem cell transplantation. Our preliminary results of RIC allo-HSCT (protocol RICE) indicate the feasability and low toxicity of allograft in heavily pre-treated children. Furthermore RIC SCT and immunomagnetic CD3/CD19 graft depletion may allow HHCT with lower toxicity and faster engraftment. CD3/CD19 depleted grafts not only contain CD34+ stem cells but also graft-facilitating cells, CD34- progenitors, dendritic and natural killer cells which may allow stable engraftment and participate to GvT effect. After haploidentical stem cell transplantation anti tumour activity exerted by donor derived NK cells could be stimulated by NK cells injections. Those effects may help to reduce the relapse rate and to impove the outcome of those patients. The investigators prospectively evaluated engraftment and immune reconstitution.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Sometimes, after surgery, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known which combination chemotherapy regimen given together with surgery, with or without autologous bone marrow or peripheral stem cell transplant, is more effective in treating newly diagnosed neuroblastoma. PURPOSE: This phase III trial is studying combination chemotherapy to see which regimen given together with surgery, with or without autologous bone marrow or peripheral stem cell transplant, works in treating infants with newly diagnosed neuroblastoma.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after chemotherapy may kill any remaining tumor cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with or without radiation therapy works in treating children with brain tumors.

RATIONALE: Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. PURPOSE: This phase II trial is studying how well umbilical cord blood works as a source of stem cells in treating patients with types of cancer as well as other diseases.

RATIONALE: Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining isotretinoin and monoclonal antibodies may kill any remaining tumor cells following surgery. It is not yet known which treatment regimen is more effective in treating neuroblastoma. PURPOSE: This randomized phase III trial is studying how well combination chemotherapy with or without filgrastim before surgery, high-dose chemotherapy, and radiation therapy followed by isotretinoin with or without monoclonal antibody work in treating patients with neuroblastoma.

The purpose of this study is to explore the effect of G-CSF combination with GM-CSF on prevention and treatment of infection in children with malignant tumor.

The purpose of this study is to evaluate the efficacy and toxicity of tandem HDCT/ASCT including high-dose 131I-metaiodobenzylguanidine (MIBG) treatment. In the present study, a single arm trial of tandem HDCT/ASCT will be carried out.

Cd276 (B7-H3) is an ideal target for car-t treatment because of its high expression on the surface of neuroblastoma, osteosarcoma, gastric cancer and lung cancer cells, but not in normal peripheral cells or tissues. In conclusion, car-t cell therapy has achieved exciting results in blood tumors, but it has been stopped in solid tumor. The main reason for the poor effect is the existence of tumor microenvironment of solid tumor, which inhibits the chemotaxis and infiltration of car-t cells to tumor site. Therefore, in this clinical experiment, we will explore the best model of car-t therapy for solid tumor by intravenous and local tumor injection, which will bring new hope to patients with osteosarcoma, neuroblastoma and gastric cancer
