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

A Randomized, Multicenter, Open-label, Phase 3 Study of the Bruton's Tyrosine Kinase Inhibitor PCI-32765 versus Chlorambucil in Patients 65 Years or Older with Treatment-naive Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma.

It has been shown that many patients with lymphoma or chronic lymphocytic leukemia (CLL)have low levels of complement. Several drugs have been approved by the Food and Drug Administration (FDA) for use in this cancer. However, these drugs are often used as combination therapies which means two or more drugs are part of the treatment. Many people, especially elderly patients, cannot put up with the use of multiple drugs because of the side effects. The main purpose of this study is to see if patients respond to therapy with human plasma (known as fresh frozen plasma or FFP) and ofatumumab. Another purpose of the study is to find out if this therapy will increase chances of getting rid of leukemia. This study will also look at the levels of complement in your blood. The levels of complement may allow better understanding of whether increasing the levels of complement by giving FFP may help control leukemia.

This is a dose finding study using a 3 + 3 dose escalation and expansion design to determine a Not Tolerated Dose (NTD), Optimal Biological Effect Dose (OBE) and / or Maximum Tolerated Dose (MTD). These data will be used to establish a Recommended Phase 2 Dose (RP2D) for the combination of CC-292 and Rituximab in subjects with CLL.

This phase II trial studies how well cyclophosphamide works in preventing chronic graft-versus-host disease after allogeneic peripheral blood stem cell transplant in patients with hematological malignancies. Giving chemotherapy and total-body irradiation before transplantation helps stop the growth of cancer cells and prevents the patient's immune system from rejecting the donor's stem cells. Healthy stem cells from a donor that are infused into the patient help the patient's bone marrow make blood cells; red blood cells, white blood cells, and platelets. Sometimes, however, the transplanted donor cells can cause an immune response against the body's normal cells, which is called graft-versus-host disease (GVHD). Giving cyclophosphamide after transplant may prevent this from happening or may make chronic GVHD less severe.

This randomized pilot clinical trial studies how well giving prolonged infusion compared to standard infusion of cefepime hydrochloride works in treating patients with febrile neutropenia. Giving cefepime hydrochloride over a longer period of time may be more effective than giving cefepime hydrochloride over the standard time.

The purpose of this study is to evaluate the safety and efficacy of NOX A12 in combination with a background therapy of bendamustine and rituximab (BR) chemotherapy in previously treated patients with chronic lymphocytic leukemia (CLL).

A good proportion of patients with chronic lymphocytic leukemia (CLL) can be managed effectively with palliative chemotherapy. However, there is a group of younger patients with poor risk disease whose life expectancy is significantly reduced. As a result, reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (allo-HCT) has been investigated as a potentially curative procedure. Recently, the European Group for Blood and Marrow Transplantation (EBMT) published a set of guidelines suggesting situations where allo-HCT might be considered a therapeutic option for CLL patients. Their conclusions were that allo-HCT was reasonable for younger CLL patients refractory to fludarabine, relapsing within two years of intensive treatment, or with p53 abnormalities requiring treatment. However, the results with RIC allo-HCT are not entirely satisfactory, and progression-free survival after allo-HCT revolves around 35-40% at 3-5 years following allo-HCT. This is due to non-relapse mortality, which is significantly associated with the development of graft-versus-host disease (GVHD), but also due to disease relapse. These relapses may occur early in the course of the transplantation, like any other hematological malignancy, but late relapses have also been reported. Several strategies have been tested in order to improve these results. The anti-CD20 monoclonal antibody rituximab, given concomitantly with allo-HCT or donor lymphocyte infusions, may reduce graft-versus-host disease and facilitate disease control. This may be due, not only to direct cytotoxicity, but also to modulation of GVHD and the graft-versus CLL effect (GVCLL). Interestingly, rituximab has been shown to promote the cross-presentation of tumor-derived peptides by antigen-presenting cells, thus enhancing the formation of cytotoxic T-cell clones and a GVCLL effect. With the addition of rituximab to the conditioning regimen, rates at 4 years for current progression-free survival (CPFS) and overall survival were 44% and 48%. The investigators hypothesize that ofatumumab, having a more potent anti-CLL activity and complement-dependent cytoxicity than rituximab, could improve disease control and modulate the GVCLL effect more effectively, thus reducing the GVHD rate and subsequently improving the non-relapse mortality and progression-free survival in the long term.

The main aims of this clinical study are to find out the maximum dose that can be given safely to patients, the potential side effects of the drug and how they can be managed. The study will also look at what happens to Anti-CD19 (DI-B4) inside the body. DI-B4 is a type of drug called an Anti-CD19 monoclonal antibody which is being used to stop the growth and kill cancerous immune cells by targeting the B-cell marker (CD-19) expressed on their surface. This drug has not been given to patients before. DI-B4 will be given weekly by intravenous infusion for four weeks. The study is in two parts. In Part 1, small groups of patients will be treated at increasing doses to find the highest safest dose and best dose for part 2 of the study. Approximately 16-20 patients will be treated in this part. In Part 2, the dose identified in Part 1 will be given to approximately 20 patients. Patients recruited to the study will receive four weeks (cycles) of treatment. They will attend an end of therapy visit eight weeks after their last dose of DI-B4, and attend follow-up visits up to eighteen months after their first dose of DI-B4. Information on the overall and progression free survival will be collected for a period up to eighteen months after the final patient is treated on the study. Patients will have blood and urine samples taken each week during treatment amongst other clinical tests. CT scans will be performed at the start of the study, at eight weeks post treatment and six months after the study start. Bone marrow biopsies and FDG-PET scans will only be taken if needed. Research blood samples will also be taken to look at what happens to the drug inside the body. It is important to explain that patients will have advanced cancer so it is unlikely that patients will benefit directly from taking part but the study may help improve future treatment of cancer.

This pilot phase II trial studies how well giving donor T cells after donor stem cell transplant works in treating patients with hematologic malignancies. In a donor stem cell transplant, the donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect.

The purpose of this study is to evaluate the efficacy and safety of ibrutinib versus rituximab in adult Asia Pacific region patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
