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

The purpose of this study is to determine the recommended dose for the combination of dasatinib and bendamustine in chronic lymphocytic leukemia (CLL).

Dasatinib and lenalidomide are both prescribed for use in patients with different cancers of the blood. This study is experimental because neither drug has been approved by the Food and Drug Administration for the treatment of chronic lymphocytic leukemia. There are few standard treatments when fludarabine is no longer effective in patients with CLL. Some patients have received additional combination therapy with fludarabine, Campath, bone marrow transplants or supportive care. Dasatinib and lenalidomide have been effective in high-risk CLL patients in other pilot mono therapy studies. The combination of dasatinib and lenalidomide has not been studied in humans before and this study is designed to test whether this combination is safe to use.

RATIONALE: Drugs used in chemotherapy, such as fludarabine phosphate, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab and bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving fludarabine phosphate together with rituximab and bevacizumab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving fludarabine phosphate together with rituximab and bevacizumab works in treating patients with B-cell chronic lymphocytic leukemia that has relapsed or not responded to treatment.

Since there is no standard rescue therapy for refractory CLL or relapsed to the purine analogous, our target is to carry out a rescue therapy combining several chemotherapy agents (CHOP) adding the synergistic effect of Rituximab in order to act against tumour-like CLL forms, with assessable size lymph nodes. Afterwards, based in other studies, we shall study the role of Alemtuzumab as drug for consolidation or improvement of responses obtained with the initial therapy (CHOP-R), acting by "cleaning" from peripheral blood and bone marrow the CLL lymphocytes that may have had remain as residual after chemotherapy induction therapy. More precisely, the addition of Alemtuzumab as maintenance treatment would increase the complete responses with negative residual disease number and may prolong the duration of the response. For this, it is necessary to have not only an adequate and rigorous clinical follow-up but also biological, i.e. being able to analyze minimal residual disease by molecular biology techniques. This is the reason of writing this phase II clinical trial protocol.

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Vaccines may help the body build an effective immune response to kill cancer cells. Giving cyclophosphamide and rituximab together with vaccine therapy may kill more cancer cells. PURPOSE: This randomized phase II trial is studying cyclophosphamide and rituximab followed by two different schedules of vaccine therapy to compare how well they work in treating patients with chronic lymphocytic leukemia.

RATIONALE: Drugs used in chemotherapy, such as bendamustine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer cell growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cell-killing substances to them. Giving bendamustine together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying the side effects of giving bendamustine together with rituximab and to see how well it works in treating patients with B-cell chronic lymphocytic leukemia that has not responded to previous treatment.

It is a single-center, open-labeled, single-arm, non-randomized investigator-initiated trial evaluating the efficacy and safety of anti-CD19 U-CAR-NK Cells Therapy combined with HSCT for B cell hematologic malignancies.

A randomized, multi-centre trial was conducted between 2013-2016, including 128 patients with untreated CLL from eight hematological clinics in Sweden. Vaccination with polysaccharide pneumococcal vaccine (PPSV23) or conjugated pneumococcal vaccine (PCV13) was performed and the results were published 2018. PCV13 showed a superior immune response, measured as OPA (opsonophagocytic assays) and ELISA (enzyme-linked immunosorbent assay), compared to PPSV23. Immune cells analyses after primary immunization will be performed. Between 2019-2021 a prospective follow up study was conducted of the same cohort and also included a control group. The study participants have been revaccinated with pneumococcal vaccines with the aim to evaluate the effect of repeated dose of PCV13. The antibody response (measured as titer with FMIA (fluorescent multiplexed bead-based immunoassay) and antibody function with MOPA (multiplexed opsonophagocytic assay) will be performed. Studies investigating the dynamics of immune cells before and after primary immunization and revaccination will be performed. The study will give important answers about the optimal vaccination strategy in patients with CLL and can improve the vaccination recommendations in immunocompromised patients.

This research is studying the safety of combining ibrutinib with the study drug LY3214996 for chronic lymphocytic leukemia (CLL), Waldenstrom's macroglobulinemia (WM), mantle cell lymphoma (MCL), or marginal zone lymphoma (MZL).

This study is designed to assess the safety, pharmacokinetics, drug-drug interactions, and determine the recommended Phase 2 doses of co administered Duvelisib and Venetoclax in participants with relapsed or refractory chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma, or indolent or aggressive non-Hodgkin lymphoma, who have not previously received a Bcl-2 or Phosphoinositide 3-kinase (PI3K) inhibitor. The Phase 2 portion of the study will preliminarily evaluate efficacy, and expand the toxicity evaluation.
