Active clinical trials for "Leukemia, B-Cell"

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.

Clinical studies of CD19 CAR-T cells in the treatment of blood and lymphatic system tumors have achieved unprecedented successes. Because of the heterogeneity of the tumor, patients often carry CD19-negative tumor cell clones that express alternative target antigens (such as CD22, CD20 and CD123). In order to effectively eradicate all tumor clones and prevent recurrence, alternative tumor antigens besides CD19 are considered for CAR-T cell targeting. In this tudy, autologous T cells are genetically modified with 4th generation anti-CD19 and anti-CD22 CARs (4SCAR19/22) using lentiviral vectors. For safety consideration, the 4SCAR is engineered with an inducible caspase 9 self-withdrawal genetic design that allows for rapid elimination of the infused CAR-T cells. Interleukin-2 has been shown to boost immune response against leukemia cells. The serum interleukin-6 level will be monitored and when it returns to normal range by day 28 after CAR-T cell infusion, patients will receive subcutaneous injection of interleukin-2, and evaluated for 24 months for safety, efficacy and persistence of CAR T cells.

The purpose of the study is to determine the maximum tolerated dose (MTD) in patients with acute lymphoblastic leukemia (ALL) and to determine the safety and tolerability of increasing doses and different infusion times of AFM11 infusion in patients with adult B-precursor ALL

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.

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.

The purpose of this study is to evaluate the safety of lenalidomide and to define the maximum tolerated escalation dose level (MTEDL) when administered by a stepwise dose-escalation schedule in subjects with relapsed or refractory B-cell CLL.

This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of CD19/CD20 Dual-CAR-T cells in patients with refractory and relapsed B-cell leukemia.

The purpose of this study is to assess the safety and tolerability of BMS-936564 (MDX-1338) in relapsed Acute myelogenous leukemia (AML) and other selected B-cell cancers and to determine the maximum tolerated dose (MTD) of the drug alone in relapsed/refractory AML

The primary objective of this study was to evaluate the safety and efficacy of the combination of fludarabine and cyclophosphamide in previously untreated CLL patients. Participants will receive fludarabine and cyclophosphamide on days 1, 2, and 3 of six 28-day cycles.
