In this single-center, open-label, no control, prospective clinical trial, a total of 20 resistant or refractory CD19+ B cell acute lymphoblastic leukemia (ALL) patients will be enrolled. CD19 CAR T cells will be administered by i.v. injection as a using a "split dose" (total dose of 5x10^6/kg-5x10^7/kg) approach to dosing:10% on day 0, 30% on day 1 and 60% on day 2. The purpose of current study is to determine the clinical efficacy and safety of CD19 CAR T cells in patients with chemotherapy resistant or refractory CD19+ ALL.
In this single-center, open-label, nonrandomized, no control, prospective clinical trial, a total of 20 resistant or refractory CD19+ B cell acute lymphoblastic leukemia (ALL) patients will be enrolled. Patients will be diagnosed according to morphologic, immunologic, cytogenetic and molecular(MICM) criteria, including bone marrow morphology, immunophenotype, cytogenetic and molecular examination. CD19 CAR T cells transduced with a lentiviral vector to express anti-CD19 scFv TCRζ:4-1BB,administered by i.v. injection as a using a "split dose" (total dose of 5x10^6/kg-5x10^7/kg) approach to dosing:10% on day 0, 30% on day 1 and 60% on day 2. This protocol will be given to subjects with unmet medical needs for which there are no effective therapies known at this time. Side effects of CD19 CAR T cells therapy will be monitored. The purpose of current study is to determine the clinical efficacy and safety of CD19 CAR T cells therapy in patients with chemotherapy resistant or refractory CD19+ ALL.

RATIONALE: Immunotoxins, such as anti-CD19 and anti-CD22, can find cancer cells that express CD19 and CD22 and kill them without harming normal cells. This may be an effective treatment fo...
This single-arm, multicenter Phase 2 trial will treat adult patients who have relapsed or refractory B-ALL with an infusion of the patient's own T cells that have been genetically modified...
This is a single arm, open-label, multi-center, phase 1/2 study, to determine the safety and efficacy of KTE-C19, an autologous anti-CD19 chimeric antigen receptor (CAR)-positive T cell th...
The trial is a single arm, single-center, non-randomized phase I clinical trial which is designed to evaluate the safety and efficacy of C-CAR011 in treatment of adult subjects with relaps...
CART-19 cells has emerged as a powerful targeted immunotherapy, showing striking responses in highly refractory CD19+ acute lymphoblastic leukemia (ALL). This study aims to assess the safe...
Post-stem cell transplantation (SCT) relapsed acute lymphoblastic leukemia (ALL) has extremely poor prognosis with median survival of less than 1 year. Donor lymphocyte infusion, second transplantatio...
Adoptive immunotherapy with chimeric antigen receptor-modified (CAR)-T cells is a rapidly growing therapeutic approach to treating patients with refractory cancer, with over 100 clinical trials in var...
Immunotherapy has demonstrated significant potential for the treatment of patients with chemotherapy-resistant hematologic malignancies and solid tumors. One type of immunotherapy involves the adoptiv...
B cell acute lymphoblastic leukemia (B-ALL) exhibits phenotypes reminiscent of normal stages of B-cell development. As demonstrated by flow cytometry, the immunophenotypes are able to determine the st...
Chimeric antigen receptors (CARs) are engineered molecules that can be introduced into T cells to enable them to target specific tumor antigens. CAR T cells targeting CD19 have shown promise in patien...
A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)
A genus in the family RETROVIRIDAE consisting of exogenous horizontally-transmitted viruses found in a few groups of mammals. Infections caused by these viruses include human B- or adult T-cell leukemia/lymphoma (LEUKEMIA-LYMPHOMA, T-CELL, ACUTE, HTLV-I-ASSOCIATED), and bovine leukemia (ENZOOTIC BOVINE LEUKOSIS). The type species is LEUKEMIA VIRUS, BOVINE.
A strain of PRIMATE T-LYMPHOTROPIC VIRUS 1 isolated from mature T4 cells in patients with T-lymphoproliferation malignancies. It causes adult T-cell leukemia (LEUKEMIA-LYMPHOMA, T-CELL, ACUTE, HTLV-I-ASSOCIATED), T-cell lymphoma (LYMPHOMA, T-CELL), and is involved in mycosis fungoides, SEZARY SYNDROME and tropical spastic paraparesis (PARAPARESIS, TROPICAL SPASTIC).
An acute leukemia exhibiting cell features characteristic of both the myeloid and lymphoid lineages and probably arising from MULTIPOTENT STEM CELLS.
A leukemia/lymphoma found predominately in children and adolescents and characterized by a high number of lymphoblasts and solid tumor lesions. Frequent sites involve LYMPH NODES, skin, and bones. It most commonly presents as leukemia.
