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

Autologous T cells engineered to express an anti-CD19 chimeric antigen receptor (CAR) will be infused back to patients with B cell malignancies, including lymphoma and leukemia. The patients will be monitored after infusion of anti-CD19 CAR-transduced T cells for adverse events, persistence of anti-CD19 CAR-transduced T cells and treatment efficacy. Objectives: To evaluate the safety and the efficacy of anti-CD19 CAR-transduced T cell therapy for patients with B cell malignancies. Eligibility: Patients between 1 and 80 years of age, who have relapsed or refractory CD19-expressing B-cell malignancies (leukemia or lymphoma) that have not responded to standard treatments. Patients with a history of allogeneic stem cell transplant who meet all eligibility criteria are eligible to participate. Patients must have adequate organ functions. Design: Peripheral blood from patients will be collected for isolation of peripheral blood mononuclear cells (PBMCs), which will be transduced with a lentiviral or retroviral vector encoding anti-CD19 CAR containing a CD28 or 4-1BB and a CD3 zeta as costimulatory domains. Patients will receive a lymphodepleting preconditioning regimen to prepare their immune system to accept modified T cells. Patients will receive an infusion of their own modified T cells. They will remain in the hospital to be monitored for adverse events until they have recovered from the treatment. Patients will have frequent follow-up visits to monitor the persistence of modified T cells and efficacy of the treatment.

The primary objective of this study is to determine the preliminary efficacy of the combination of tirabrutinib and idelalisib with obinutuzumab in adults with relapsed or refractory chronic lymphocytic leukemia (CLL). The study has a 6 participant per arm safety run-in to evaluate safety prior to the enrollment of subsequent participants. The treatment period is adaptive, with a duration of active treatment up to two years and a total follow-up on study for up to 30 days post end of treatment, or up to Week 25 should a participant discontinue treatment prior to Week 25 for reasons other than disease progression.

The goal of this clinical research study is to learn if giving genetically changed immune cells, called CAR-NK cells, after chemotherapy will improve the disease in stem cell transplant patients with relapsed (has returned) and/or refractory (has not responded to treatment) B-cell lymphoma or leukemia. Also, researchers want to find the highest tolerable dose of CAR-NK cells to give to patients with relapsed or refractory B-cell lymphoma or leukemia. The safety of this treatment will also be studied. This is an investigational study. The making of and infusion of genetically changed NK cells and the drug AP1903 (if you receive it, explained below) are not FDA approved or commercially available for use in this type of disease. They are currently being used for research purposes only. The chemotherapy drugs in this study (fludarabine, cyclophosphamide, and mesna) are commercially available and FDA approved. Up to 36 patients will take part in this study. All will be enrolled at MD Anderson.

The primary objective of this study is to determine the preliminary efficacy of the combination of tirabrutinib (formerly GS-4059) and entospletinib with obinutuzumab in adults with relapsed or refractory chronic lymphocytic leukemia (CLL).

Background: Chronic Lymphocytic Leukemia (CLL) is the most common leukemia in the occidental countries. Until now, it is considered a chronic disease without a cure. The development of new molecular therapies have showed that the cure may be an option. This protocol propose a triple sequential therapy with three direct therapies for the leukemic cell: an inhibitor of Bruton´s tyrosine kinase (ibrutinib), a second generation monoclonal antibody versus CD20 (obinutuzumab) and a BCL-2 inhibitor (venetoclax) as treatment of first or second line in CLL. Objective: Negativize the minimal residual disease and by this way obtain longer survivals (overall survival and relapse free survival). Design: This is a multicenter, longitudinal, experimental, open, non-randomized and non-comparable study coordinated by the "Grupo Cooperativo de Hemopatías Malignas" situated on Hospital Angeles Lomas in Huixquilucan, México. The study, is a phase II clinical study that will employ three target therapy drugs in sequencing phases. It will start with a BTK inhibitor as induction, later an anti-CD20 will be used for consolidation and it will end with a BH3 analog as maintenance for one year. The primary outcome is the negativization of minimal residual disease.

The purpose of this study is to determine the safety profile and tolerability of S 55746 in patients with CLL, B-Cell NHL and MM, in terms of Dose-Limiting Toxicities (DLTs), Maximum Tolerated Dose (MTD) and determine the Recommended Phase 2 Dose (RP2D) through safety profile (DLT, MTD), PK profile, PD profile and preliminary efficacy.

The purpose of this trial is to identify the tolerable dose of BI-1206 (both alone and in combination) for patients with B-cell lymphoma and leukaemia and further evaluate BI-1206 alone and in combination with an anti-CD20 antibody.

This study will evaluate the safety, antitumor activity and preliminary pharmacokinetics of an investigational drug product, DTRMWXHS-12, in patients with chronic lymphocytic leukemia or other B-cell lymphomas. DTRMWXHS-12 will be evaluated as a single agent, and in combination. This study will be conducted in two parts: phase Ia and Ib. Both parts will explore escalating doses of DTRMWXHS-12. The phase Ia study will evaluate DTRMWXHS-12 monotherapy. The phase Ib study will evaluate DTRMWXHS-12 combinations.

The purpose of the study is to investigate the safety of the investigational drug called cirmtuzumab when given for a duration of 6 to 12 months. Cirmtuzumab is a type of drug called a monoclonal antibody. This drug is designed to attach to a protein called ROR1 that is on the surface of chronic lymphocytic leukemia (CLL) cells. This blocks growth and survival of the CLL cells. ROR1 is rarely expressed on healthy cells so this drug should target the cancer cells. Cirmtuzumab is considered experimental because its use is not approved by United States (US) Food and Drug Administration (FDA). Although there is evidence from tests on laboratory animals that cirmtuzumab can decrease the number of CLL cells, the investigators do not know if this will work in humans. Therefore, the goal of this study is to see if cirmtuzumab is safe and tolerable in study participants when given for a duration of 6 to 12 months.

This study is designed to determine the recommended phase 2 dose (RP2D), and the safety, and efficacy of durvalumab as monotherapy and when given in combination with lenalidomide and rituximab; ibrutinib; or bendamustine and rituximab at the RP2D in adults with lymphoma or chronic lymphocytic leukemia (CLL).
