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

The purpose of this study is to evaluate the safety and optimal dose of PCAR-119 in patients who are going to receive stem cell transplantation but without available treatment to achieve complete remission prior to the transplant.

Efficacy and Safety of ibrutinib in patients with chronic lymphocytic leukemia and other indolent B-cell lymphomas who are chronic hepatitis B virus carriers or occult hepatitis B virus carriers

This is a phase I study of BTK inhibitor CT-1530 in patients with relapsed or refractory B cell non-Hodgkin lymphoma (B-NHL), chronic lymphocytic leukemia (CLL) or Waldenstrom's macroglobulinemia (WM). The purpose of the study is to determine the MTD/RP2D of CT-1530, and evaluate its safety and tolerability as monotherapy in subjects with relapsed or refractory B cell non-Hodgkin lymphoma (B-NHL), chronic lymphocytic leukemia (CLL) or Waldenstrom's macroglobulinemia (WM).

The present study evaluates the safety and efficacy of humanized Chimeric antigen receptor T cells (CAR-T) in treating recurrent or refractory B cell malignancy targeting CD19 with a humanized scFv. All participants will receive autologous chimeric antigen receptor engineered T cells.

CD19-directed CAR-T cell therapy has shown promising results for the treatment of relapsed or refractory B-cell malignancies; however, a subset of patients relapse due to the loss of CD19 in tumor cells. Dual Specificity CD19 and CD20 or CD22 CAR-T cells can recognize and kill the CD19 negative malignant cells through recognition of CD20 or CD22. This is a phase 1/2 study designed to determine the safety of the allogenic gene-edited dual specificity CD19 and CD20 or CD22 CAR-T cells and the feasibility of making enough to treat patients with relapsed or refractory hematological malignancies.

Chronic Lymphoid Leukemia (CLL) is the most common type of leukemia (cancer of blood cells) in adults affecting men more so than women. The main objective of this study is to assess the how effective venetoclax (Venclexta) in combination with Obinutuzumab is in treating Chronic Lymphocytic Leukemia (CLL). Effectiveness is assessed by achievement of best response. Venetoclax is an approved drug developed for the treatment of CLL. Approximately 50 adult participants with previously untreated CLL will be enrolled in approximately 10 to 15 sites in Russian Federation. Participants will receive oral venetoclax tablets in combination with intravenous (IV) Obinutuzumab as prescribed by the physician prior to enrolling in this study in accordance to the local practice and label. There may be a higher burden for participants in this study compared to standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

The objective of this study is to improve medication, symptom, and disease management of patients with hematological malignancies and multiple chronic conditions (2 or more conditions in addition to cancer) through care coordination between pharmacists working in oncology practices and those working in primary care practices (Pharmacists Coordinated care Oncology Model [PCOM]). This is a pilot study in which the investigators will examine the association between outcome measures, but the study design and sample size are insufficient to quantify the impact of OAA initiation or OAA adherence on adherence to chronic medications. This pilot study and data analyses are being done in preparation for a larger, controlled study.

This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.

Chronic Lymphocytic Leukemia (CLL) is still an incurable disease. However recent advances have established correlation between the quality of the response (in particular achievement of negativity of minimal residual disease (MRD) and progression free and overall survival. That is why MRD negative complete remission (CR) is the current goal in CLL treatment. The association of Rituximab fludarabine cyclophosphamide leads to the best response rate with 52 to 72% CR in "medically" fit untreated CLL patients. MRD results in this setting are still preliminary and around 50%. However many other situations (unfit, elderly, relapse, haematological toxicity leading to early interruption of treatment…) are associated with much lower response rate that would be improved by consolidation treatment. Monoclonal antibodies are the treatment of choice for consolidation because of sparing marrow and targeting CLL cells. Alemtuzumab has been used for this purpose and results confirm improvement of CR and MRD negative responses but alemtuzumab induced immunodeficiency lead to unacceptable infectious complications. Rituximab monotherapy induces low response rate at standard dose regimen. This is at least partially due to shaving of CD20, mechanism by which CD20 is lost from the leukemic cells but these cells are not cleared. Using low doses of rituximab reduced shaving and allowed CLL cells clearance by the mononuclear phagocytic system. Such low doses of rituximab can be administered subcutaneously. The investigators then propose subcutaneous low dose rituximab in consolidation to CLL patients responding after induction but having not achieved MRD negative CR.

Patients with advanced chronic lymphocytic leukemia (CLL) have a poor long-term prognosis. Allogeneic stem cell transplantation (SCT) in patients with CLL has only rarely been performed in the past because the clinical outcome after myeloablative conditioning was poor, mainly due to the high treatment-related mortality. However long-term disease-free survival after allogeneic SCT has been reported. Recently it has been demonstrated by our group and others that non-relapse mortality can be reduced significantly with the use of reduced-intensity conditioning regimens. Yet, graft versus host disease (GVHD) remains an important problem in this setting. Alemtuzumab is an effective drug for the treatment of patients with advanced CLL and has been successfully applied for GVHD-prophylaxis in the setting of myeloablative and reduced-intensity conditioning regimens. The goal of the present study is to evaluate the role of alemtuzumab as part of a fludarabine-based reduced intensity conditioning regimen for allogeneic SCT in patients with advanced CLL.
