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

This is a Phase II trial testing disease-specific myeloablative conditioning regimens for preparatory cytoreduction of patients receiving allogeneic HLA-compatible related or unrelated transplants of GCSF-mobilized peripheral blood stem cells (PBSC) depleted of T-cells by positive selection of CD34+ progenitor cells using the CliniMACS system. The CliniMACS Fractionation system is a method that positively selects CD34+ progenitor cells from PBSC by immunoadsorption of cells binding on anti CD34 monoclonal antibody to paramagnetic beads, which can then be isolated by passage through a magnetized column and released by agitation of beads. Two conditioning regimens have been used successfully with an alternative similar system, isolex, which is no longer being manufactured.

This is an observational retrospective and prospective multicenter study aimed at describing the role of the COVID -19 prophylaxis with Tixagevimab and Cilgavimab in CLL or indolent B-NHL patients who received first COVID-19 prophylaxis dose between March 2022 and October 2022.

The purpose of the project is to set up a national, prospective, longitudinal, multicenter registry platform to document uniform data on characteristics, molecular diagnostics, treatment and course of disease, to collect patient-reported outcomes and to establish a decentralized biobank for patients with hematological malignancies in Germany.

Chronic lymphocytic leukaemia (CLL) is the most common adult blood cancer in the United Kingdom. CLL means that many cancer cells appear in the blood, bone marrow and other tissues, for example, the spleen where some blood cells reside. Most patients with CLL have been diagnosed by chance, have no symptoms as a result of CLL, and do not need urgent treatment. However, when the cancer cells build up, people experience symptoms of CLL, and treatment is required. One of the current treatments for CLL is chemo-immunotherapy, that targets and kills cancer cells in the blood. However, this treatment does not kill all cancer cells. Some cancer cells survive by 'hiding' in the bone marrow and tissues, like the spleen, where the treatment cannot get to, this is called minimal residual disease (MRD). MRD eventually builds up and patients experience symptoms of CLL again. New approaches to detect and treat MRD are needed. Research has shown, that the number of blood cells, increases after exercise and that many of these blood cells come from the bone marrow and other tissues. This study will investigate if exercise can move CLL cancer cells that are 'hiding' in the bone marrow and other tissues into the blood, thus improving the detection of MRD. By moving cancer cells into blood, the investigators also think this will improve the way chemo-immunotherapy works. In this study, the investigators will investigate the number of cancer and natural killer (NK) cells in the blood after exercise, in three different groups of people with CLL: before treatment; during treatment; and after treatment has finished.

Ofatumumab is a fully-human monoclonal antibody that exhibits high binding affinity to an antigen on the surface of B lymphocytes. Antigen engagement by ofatumumab results in maximal B-cell killing through complement-dependent cytotoxicity and antigen-dependent cellular cytotoxicity in both antigen high- and low-expressing cells. Recent research has shown that ofatumumab-dependent B-cell depletion provides clinical benefit to subjects with CD20-positive cancers such as chronic lymphocytic leukemia (CLL). The purpose of the current study is to assess the impact of ofatumumab on electrocardiographic parameters with particular focus on cardiac repolarization (QTc interval duration) in subjects with refractory CLL. Subjects enrolled in this open-label, single-arm trial will receive ofatumumab at the highest clinical dose (2000 mg) studied or planned for study. Ofatumumab will be administered as eight weekly intravenous (IV) infusions followed by four monthly infusions, beginning in Week 13, across a 25-week treatment period. Cardiovascular effects will be evaluated during treatment through routine 12-lead electrocardiographic (ECG) monitoring. The pharmacokinetic relationship between plasma concentration of ofatumumab and its effect on QTc interval duration will be examined. Specifically, ECG assessments will be collected in triplicate at baseline, at the time of maximum ofatumumab concentrations periodically on-therapy, and at the end of treatment. After completion of the final ofatumumab infusion, subjects will continue to be followed for safety and efficacy for six months relative to the last ofatumumab dose.

RATIONALE: Ondansetron may help lessen or prevent nausea and vomiting in patients undergoing stem cell transplant. PURPOSE: This phase II trial is studying how well ondansetron works in preventing nausea and vomiting in patients undergoing stem cell transplant.

RATIONALE: Lithium carbonate may be an effective treatment for intestinal graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying lithium carbonate in treating patients with acute intestinal graft-versus-host-disease after donor stem cell transplant.

This phase II trial studies how well the DIScussion of COst (DISCO) application (app) works in improving financial outcomes in patients with hematologic cancer. The DISCO app is an electronic, highly scalable and tailorable education and communication intervention that may help researchers learn more about improving how patients and oncologists discuss cancer treatment costs

This trial studies the effect of a digital health coaching program on self-efficacy and patient reported outcomes of patients with acute myeloid leukemia or chronic lymphocytic leukemia that is newly diagnosed. A digital health coaching program may help leukemia patients report information about their health while receiving treatment, which may lead to improvement in overall health.

The main purpose of this study is to evaluate the effects of repeat dosing of ibrutinib on the single-dose pharmacokinetics (PK) of oral contraceptives (OC - ethinylestradiol [EE] and levonorgestrel [LN]), the cytochrome P450 (CYP)2B6 probe bupropion and the CYP3A4 probe midazolam; and to evaluate the effects of single-dose ibrutinib on the single-dose PK of the CYP3A4 probe midazolam in female participants with B cell malignancy.
