Active clinical trials for "Leukemia, Lymphocytic, Chronic, B-Cell"

This study will collect data on safety, effectiveness and patient acceptance of MabCampath treatment under daily life conditions.

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.

The purpose of this study is to document the pharmacological treatment strategies used in treatment naïve and previously treated relapsed/refractory iNHL/CLL patients in the Middle East and North African (MENA) region. This study will also record encountered tumor subtype and stage and the instituted pharmacological treatments, as well as assess the clinical outcomes of treatments.

The purpose of this study is to investigate efficacy and safety of fresh frozen plasma(FFP), high dose methylprednisolone(HDMP) and rituximab for ultra-high risk chronic lymphocytic leukemia.

Despite advancement in chemotherapy, radiotherapy and haematopoietic stem cell transplant (HSCT), and the recent introduction of more targeted therapies, a substantial proportion of patients with B-cell malignancies, such as B-cell chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin's lymphoma (NHL) still succumb to their malignancies. For CLL and low-grade NHL, cure is achievable only with HSCT but such aggressive approach is not justified as the initial therapy for most patients who have indolent disease; when disease has progressed, transplant is either not feasible or ineffective. For high-grade B-cell NHL, the availability of Rituximab has improved disease outcome but treatment failure portends nearly inevitable death from disease or treatment-related complications. Thus, newer, more effective therapies for patients with B-cell malignancies are urgently needed. The present study translates recent laboratory findings into clinical application. In patients with B-cell malignancies receiving the anti-CD20 antibody Rituximab as standard therapy, the study aims to assess the feasibility and safety, as well as explore the efficacy, of infusing autologous T-lymphocytes engineered to express a CD16-41BB-CD3zeta chimeric receptor which mediates antibody-dependent cell cytotoxicity. Receptor expression is achieved by electroporation of mRNA.

RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous or donor-derived T cells may make the body build immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with B-cell leukemia or lymphoma that is relapsed (after stem cell transplantation or intensive chemotherapy) or refractory to chemotherapy.

This study will provide long-term follow-up for patients who have received treatment with a Juno CAR T-cell product in a Juno-sponsored clinical trial. In this study, patients will be followed for up to 15 years after their last dose of Juno CAR T cells for evaluation of delayed adverse events, presence of persisting CAR T-cell vector sequences, presence of replication-competent retrovirus (RCR) or lentivirus (RCL), and survival.

Protocol YY-20394-001 is a phase I open-label, first in human, dose escalation study to assess the tolerability, pharmacokinetics (PK) and efficacy of YY-20394 in patients with relapse or refractory B cell malignant hematological tumor.

This is a single-arm open-label phase I study to determine the effect of CD19- CAR-T Cells infusion followed by allogeneic stem cell transplantation in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma.

This study involves adding the kinase inhibitor Ruxolitinib to Ibrutinib to treat Chronic Lymphocytic Leukemia (CLL).
