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

A prospective, open-label, multicentre phase-II trial of ibrutinib plus venetoclax plus obinutuzumab in physically fit (CIRS ≤ 6 & normal creatinine clearance) and unfit (CIRS > 6 & creatinine clearance ≥ 50 ml/min) patients with previously untreated chronic lymphocytic leukemia (CLL) with TP53 deletion (17p-) and/or mutation

Daily intake of extra virgin olive oil (EVOO), which is the major component of the Mediterranean diet and also a source of monounsaturated fat, may be partly responsible for the increased life expectancy of the Mediterranean people. A high dietary intake of EVOO is correlated with lower incidence of cancer, cardiovascular disease, metabolic diseases, Alzheimer's disease and osteoporosis Oleocanthal, a phenolic derivative of extra virgin olive oil, has important health promoting anti-cancerous properties, since it can inhibit the growth and promote the apoptosis of several cancer cells. The purpose of the present study was to investigate the effect of dietary intake of olive oil rich in oleocanthal on hematological, metabolical, cell progression markers and disease progression in patients with Chronic Lymphocytic Leukemia. The aim is also to study the possible association of apoptosis in the mechanism of action of virgin olive oil phenols in a patient with CLL in order to find the possible mechanism of the cellular action of oleocanthal in neoplasia. After the screening of >300 EVOO samples the investigators selected an EVOO with high oleocanthal and oleacin concentration of 416 and 284 mg/Kg respectively (EVOO OC/OL). Pilot dietary intervention was made in a group of 21 patients with chronic lymphocytic leukemia (CLL) who did not follow any treatment. EVOO was administered 40 ml/day for six months. Biochemical, hematological and molecular markers were studied six month before the intervention and six month during the intervention

This is a single center, single arm, open-label, phase I study to evaluate the safety and efficacy of CD19/CD20 Dual-CAR-T cells in patients with refractory and relapsed B-cell leukemia.

The Chronic Lymphocytic Leukemia (CLL) Research Consortium (CRC) is conducting a two-arm, multi-center phase II trial of Revlimid® and rituximab for Relapsed or Refractory CLL for patients under the age of 65 and patients 65 years and older. Lenalidomide (Revlimid) is an immunomodulatory agent with promising clinical activity in CLL and is FDA approved for treatment of relapsed multiple myeloma and 5q-myelodysplastic syndrome. Rituximab (Rituxan) is a monoclonal antibody to CD20 that is approved for the treatment of CLL. The primary objective of this study is to determine the overall response rate of the combination of Revlimid® and rituximab in previously treated CLL patients. All patients will receive treatment with Revlimid® starting at a low dose that will be dose escalated based on individual patient tolerability. The combination of Revlimid and Rituximab will be administered for a maximum of 7 cycles. Patients with residual leukemia following seven cycles of treatment with the combination may elect to continue on protocol for an additional 6 cycles of single agent Revlimid® consolidation.

This phase II trial studies how well dasatinib works in treating patients with chronic lymphocytic leukemia (CLL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Background: After allogeneic (donor) stem cell transplantation, a new immune system grows in the patient from the transplanted donor stem cells and lymphocytes (type of immune cell). Donor lymphocytes, unlike the patient s own lymphocytes, often can recognize the patient s tumor cells as being foreign and destroy them. It is thought that tumor shrinkage after stem cell transplantation is the result of donor T lymphocytes, or T cells. Some studies show that patients with tumors that have T cells are better able to keep tumor growth in check. Patients who have had donor stem cell transplantation may have donor T cells in their tumors that can recognize and fight their cancer. Compared with donor T cells taken directly from the donor and infused into the patient, donor T cells found in patients tumors may be specific for the cancer cells and thus better able to attack tumor. Also, because the T cells found their way to the tumor, they may be less likely to recognize and attack non-tumor tissues than the T cells given in donor lymphocyte infusions. The T cells may be especially effective at controlling tumor if they are given an additional stimulus to become active. Costimulation is the name of the body s natural process for providing an extra stimulus, and can be performed on cells in the laboratory. Costimulation can produce large numbers of activated cells that may be able to attack cancer cells and shrink tumors. Objectives: -To evaluate the ability of lymphocytes found in tumors from patients who have received donor stem cell transplants to control their tumor growth. Eligibility: -Patients between 18 and 75 years of age with a B-cell cancer that has continued to grow or recurred after remission following allogeneic stem cell transplantation. This includes patients who have received transplants from unrelated donors and cord blood. Design: Immune cells are collected from patients blood and blood from their stem cell donor. Patients undergo surgery to remove their tumor and a small piece of skin. In the laboratory, donor T cells are isolated from the tumor and costimulated to expand the number of cells and activate them. The expanded, activated T cells as infused into the patient. Patients have a needle biopsy and possibly surgery to remove a sample of remaining tumor for research studies. Patients are followed at the NIH clinic 48 hours after the cell infusion, and again at 1, 2, 4, 8 and 12 weeks after the infusion. Tumor size is monitored every month with CT scans, and possibly also with a PET or bone marrow aspiration and biopsy, for the first 3 months after the cells are infused. Thereafter, visits are less frequent (every 3 months, then every 6 months, and then yearly) during a minimum 5-year follow-up.

The purpose of this study is to determine the efficacy and safety of a fixed-dose, daily regimen of orally administered PCI-32765 combined with ofatumumab in subjects with relapsed/refractory CLL/SLL and related diseases

The purpose of this study is to establish the safety of orally administered PCI-32765 in combination with fludarabine/cyclophosphamide/rituximab (FCR) and bendamustine/rituximab (BR) in patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma(SLL).

This was a Phase 1 multicenter study of bendamustine, rituximab and TRU-016 (BRT) in subjects with relapsed indolent B-cell lymphoma. This was a multiple-dose escalation study to determine the maximum-tolerated dose (MTD) of TRU-016 given in combination with rituximab and bendamustine and to determine a safe dosing regimen for the combination in up to 12 subjects with relapsed indolent lymphoma. The originally planned Phase 2 portion, an open-label, randomized study to evaluate the efficacy of BRT compared with BR, was not conducted.

This phase I/II trial studies the safety and toxicity of post-transplant treatment with donor T cells engineered to express a chimeric antigen receptor (CAR) targeting CD19 in patients who have had a matched related allogeneic hematopoietic stem cell transplant for a CD19+ B cell malignancy.
