Filter by:This is a single center, single arm, open-label pilot study to determine the feasibility and safety of a single dose administered as spilt fractions of autologous T cells expressing CD22 chimeric antigen receptors expressing tandem TCRζ and 4-1BB (TCRζ/4-1BB) co-stimulatory domains (referred to as "CART22" cells) in pediatric patients with relapsed or refractory B-cell acute lymphoblastic leukemia.
Objectives: The purpose of this study is to evaluate the safety and prognosis of New Cluster of Differentiation Antigen 19-chimeric Antigen Receptor T (nCAR19-T) Cells in the treatment of recurrent/refractory B-cell tumor and the Optimal dosage of nCAR19-T cell therapy. Methods: This study designs a novel therapy using nCAR19-T. 20 patients will be enrolled. Cyclophosphamide 500 mg - 2000 mg/m2 (day 2) with or without Fludarabine 30 mg/m2 /day, 4 days (day-6,-5,-4,-3); nCAR19-T transfusion：day 0(5×10※5/kg，1×10※6/kg，3×10※6/kg). According to the National Cancer Institute (NCI) standard (CTCAE), they will be observed 24 weeks long. Follow-up survey after the clinical study: within 1 months, once a week; then once a month for 1 years; and then once a year, a total of 15 years.
This Phase I, multiple ascending dose study will seek to enroll subjects with relapsed/refractory Chronic B-cell Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL) with confirmed and measurable disease who have received standard treatment with at least one anti-CD20 antibody (e.g.; rituximab, ofatumumab) containing front-line regimen that resulted in initial response, followed by relapse/recurrence and who are not eligible for any further approved biologic therapy, chemotherapy and/or autologous stem transplantation and/or refuse alternative approved therapies and/or are unlikely to achieve clinical benefit from any therapy of higher priority by Investigator assessment.
This is a phase-II study to evaluate the efficacy of a salvage regimen in children with relapsed T-cell ALL or lymphoma. Peg-asparaginase, mitoxantrone, intrathecal triples (IT) (intrathecal methotrexate/hydrocortisone/cytarabine) (ITMHA) and dexamethasone are commonly used drugs to treat relapsed or refractory acute lymphocytic leukemia or lymphoma (ALL). In this study, the investigators want to know if adding three drugs called panobinostat, bortezomib and liposomal vincristine (VSLI) to this regimen will result in remission (no signs or symptoms of leukemia or lymphoma). - Panobinostat has been approved by the FDA for treating adults with multiple myeloma, but it has not been approved for use in children and has not been given together with the other drugs used in this study. It has not been widely studied in children. - VSLI has been approved by the FDA for adults with relapsed or refractory ALL, but has not yet been approved for treating children with leukemia or lymphoma. - Bortezomib has been approved by the FDA for treating adults with a cancer called multiple myeloma and adults with relapsed mantle cell lymphoma; it has not been approved for treating children. PRIMARY OBJECTIVE: - To estimate the complete remission (CR) rate for patients with T-cell lymphoblastic leukemia and lymphoma in first relapse. SECONDARY OBJECTIVES: - To evaluate minimal residual disease (MRD) levels at end of each block of therapy. - To describe the toxicities of vincristine sulfate liposome injection (VSLI) when used in combination with chemotherapy and bortezomib.
Background: - Gene therapy is a way to treat or prevent disease using genes. It is monitored very closely by regulators because there can be long-term, unexpected side effects. NIH is required to try to contact people who have been treated with gene therapy at least annually for up to 15 years. This is to see if they have had any bad side effects. This trial does not include any therapy and is only for patients previously treated on gene-therapy trials at the NCI Surgery Branch who are no longer enrolled on their original gene therapy clinical trial. Objective: - To collect of long-term follow-up data on people who have been in gene transfer studies. This follow-up is required by regulators. Eligibility: - People age 18 and older who have been in a previous NCI Surgery Branch gene therapy research study. Design: - After they get the genetically modified cells, participants will: - Have blood drawn 3, 6, and 12 months later. - Have an annual clinic visit for the next 4 years. They will have a physical exam. They will answer questions about any signs of neurological, autoimmune, or blood disorders, or any new cancers. Blood may be drawn. - Be called or emailed annually for the next 10 years. They will answer health questions. Blood samples may need to be taken. - Participants will be asked for their current address and phone number. They will also be asked for the address and phone number of 1 or 2 people who will know their whereabouts. One of these should be a family member if possible, - At the time of the participant s death, researchers will request permission from their family for an autopsy.
This study is a dose escalation, and cohort expansion study in subjects with advanced cancer for which no standard therapy exists. Subjects must have received prior treatment for cancer that has not worked, or has stopped working.
Chimeric antigen receptor (CAR) T cells targeting CD19 will be evaluated for safety and efficacy in patients with B cell lymphoma or leukemia. The CAR consists of a CD19 targeting antibody scFv with three intracellular signaling domains derived from CD3 zeta, CD28 and 4-1BB. Autologous T cells will be gene engineered with the CAR gene using a retrovirus vector. Prior to T cell infusion, the patients will be subjected to preconditioning treatment. After T cell infusion, the patients will be evaluated for 24 months for adverse reactions, persistence of CAR T cells and efficacy.
Patients with relapsed leukemia often develop resistance to chemotherapy. For this reason, we are attempting to use a patient's own T cells, which can be genetically modified to expresses a chimeric antigen receptor(CAR). The CAR enables the T cell to recognize and kill the leukemic cells though the recognition of CD19, a protein expressed on the surface of the majority of pediatric ALL. This is a phase I study designed to determine the maximum tolerated dose of the CAR+ T cells and define the toxicity of the treatment. As a secondary aim, we will be looking at the efficacy of the T cells on eradicating the patient's leukemic cells.
This is a study for children who have been previously treated for Leukemia/Lymphoma. In particular, it is a study for people who have a type of Leukemia/Lymphoma that involves B cells (a type of white cell), which contain the cancer. This is a new approach for treatment of Leukemia/Lymphoma that involves B cells (tumor cells). This study will take the subject's white blood cells (T cells) and modify them in order to target the cancer. The subject's T cells will be modified in one or two different ways that will allow the cells to identify and kill the tumor cells (B cells). Both ways of modifying the cells tells the T cells to go to the B cells (tumor cells) and turn "on" and potentially kill the B cells (tumor cells). The modification is a genetic change to the T cells, or gene transfer, in order to allow the modified T cells to recognize your tumor cells but not other normal cells in the subject's body. These modified cells are called chimeric antigen receptor 19 (CART19) T-cells.
The aim of the trial is to test whether adding 6 injections of rituximab to standard "Lymphome malin B" LMB chemotherapy regimen improves the Event Free Survival (EFS) compared with LMB chemotherapy alone in children / adolescents with advanced stage B-cell Non-Hodgkin Lymphoma (NHL) / B-Acute Leukemia (B-AL)(stage III and LDH > Nx2, any stage IV or B-AL).
