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

The application of positron emission tomography with lymphoproliferative diseases today provides diagnostic and therapeutic information of major importance , especially in terms of speed and quality of response to treatment. The radiopharmaceutical used in clinical practice for this exam is fluorodeoxyglucose 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose ([18F]-FDG) . However , the uptake of this tracer is not elective in lymphoid tissues , with a lack of specificity. In addition , the avidity of this tracer is unequal according to the histological subtype (lack of sensitivity). To try to improve the results of this clinical exploration of lymphoid malignancies, the investigators developed a new radiopharmaceutical ( [18F] - fludarabine ). The idea of transforming the fludarabine radiopharmaceutical is based on the existence of a fluorine atom in the molecule and the pharmacokinetic characteristics of this drug. The [18F]-Fludarabine is a new radiopharmaceutical reproducing the same dosage formulation of fludarabine , a drug used for the treatment of certain types of lymphoproliferative diseases, especially those where the tumor cells have a low proliferation kinetics . This drug is used in therapy in particular pharmacokinetic effect for a high affinity for the lymphoid tissue . Preclinical results on normal and lymphoma xenograft -bearing mice showed a specificity restricted to lymphoid tissue fixation with [18F]-Fludarabine compared with [18F]-FDG . Based on these encouraging results , the investigators propose in this work to explore the Dosimetry and Biodistribution of [18F] - Fludarabine in human lymphoproliferative diseases : 1)A first group of patients with non-Hodgkin's large cell lymphomas in which it already has a wealth of experience in exploration [18F]-FDG, and 2) a second group of patients with chronic lymphocytic leukemia, where the results of the exploration [18F]-FDG are considered disappointing and did not, for this reason, experienced clinical development.

This phase II trial studies how well brentuximab vedotin, bendamustine, and rituximab work in treating patients with B-cell non-Hodgkin lymphoma that has returned after a period of improvement or has not responded to previous treatment. Monoclonal antibody-drug conjugates, such as brentuximab vedotin, use antibody to target chemotherapy in cancer cells. Drugs used in chemotherapy, such as bendamustine, work in different ways to kill cancer cells. Monoclonal antibodies, such as rituximab, kill the cancer cells directly, but also harness the immune system to kill the cancer cells. Adding brentuximab to rituximab may improve response rates in CD30 positive, CD20 positive Relapsed Refactory NHL.

Gene transfer is a process in which the DNA (genetic material) of certain cells is changed. In this study, gene transfer will be performed on a type of white blood cell (called T cells) to recognize leukemia cells in the same person the T cells were collected from. The goal of this clinical research study is to learn if it is safe to give these genetically-changed T cells back to patients with CLL/SLL. Researchers also want to learn if these cells can help to attack CLL/SLL cells.

RATIONALE: American ginseng extract may prevent or reduce acute respiratory illness in patients with chronic lymphocytic leukemia. It is not yet known whether American ginseng extract is more effective than a placebo in preventing respiratory infections. PURPOSE: This randomized trial is studying the side effects of American ginseng extract and to see how well it works compared with a placebo in preventing respiratory infection and in reducing antibiotic use in patients with chronic lymphocytic leukemia.

This is a Phase 2b, open-label, multicenter, global study assessing the safety and efficacy of ABT-263 in subjects with B-cell CLL who have failed at least one prior fludarabine-containing regimen.

This research study aims to address the limited understanding of the challenges faced by specific demographic groups of chronic lymphocytic leukemia patients in their participation in clinical trials. This trial will scrutinize the experiences of patients diagnosed with chronic lymphocytic leukemia as they take part in a separate medical intervention clinical trial. The focus will be on tracking the rates of completion and withdrawal among these individuals. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future chronic lymphocytic leukemia patients.

This is a multicenter, prospective, observational cohort study to comprehensively and longitudinally evaluate and characterizes the cardiovascular events with CLL patients who are initiating treatment with a Bruton's tyrosine kinase (BTK) inhibitor ibrutinib or acalabrutinib.

The goal of this observational study is to assess in the cohort of CLL patients enrolled in the front-line GIMEMA LLC1114 study who discontinued ibrutinib the time to subsequent treatment. The main question it aims to answer is: • The 12 and 24-month TTNT measured from the time of ibrutinib discontinuation due to reasons other than CLL progression, Richter syndrome, malignancy or death, or lost to the follow-up. Participants will be observed for the duration of the study.

This study investigates families with at least two cases of B-cell lymphoproliferative disorders (LPD), and evaluates the prevalence of LPD in families, the relationship between medical history, genetic factors, and the risk of familial LPD, and various clinical outcomes for these families in a multiethnic population of Jews and Arabs in Israel.

The aim of this research study is to use advanced immunology laboratory analysis to identify a more precise blood test that will predict infection risk in patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma (CLL/SLL) or Multiple Myeloma (MM).
