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

This observational study will evaluate the safety and efficacy of rituximab in combination with chemotherapy in first- and second-line treatment of participants with cluster of differentiation 20 (CD20)-positive B-cell chronic lymphocytic leukemia. Data will be collected from eligible participants receiving rituximab according to the Summary of Product Characteristics (SPC) during 6 months of treatment.

The purpose of the study is to evaluate the overall and disease free survival of recipients who have received G-CSF mobilized stem cells from HLA matched sibling donors.

Randomized unblinded interventional clinical trial: Arm Intervention Experimental arm (n=150): Intervention group Administration of the MyPal ePRO system the intervention group will use the ePRO tools provided in the project. Standard care arm (n=150): no intervention besides general palliative care if required general palliative care if required. Patients will be randomly assigned in a 1:1 fashion to use the MyPal system and receive related-intervention versus general palliative care, stratified by cancer type (i.e. CLL vs MDS), using a computer-generated number sequence, which will be concealed until after group assignment.

Retrospective evaluation on the effect of splenic irradiation on clinical and hematological response and toxicity in patients with chronic lymphatic leukaemia (CLL).

The purpose of this study is to assess safety and effectiveness of extended bendamustine in the treatment of chronic lymphocytic leukemia (CLL).

The purpose of this study is to collect a blood sample from patients with Chronic Lymphocytic Leukemia (CLL) and from volunteers without CLL.

The purpose of this study is to provide early access to Ibrutinib treatment for participants with relapsed or refractory Chronic Lymphocytic Leukemia (CLL) and collect additional safety data while the medication is not commercially available.

There are naturally occuring variations in the genetic makeup of all of us. Some of these variations may contribute to a change in susceptibility toward different diseases or change the prognosis. We are studying these genetic variations in patients with leukemia. The genes we are studying are those which influence detoxification of drugs and toxins.

Lymphoid hemopathies are a group of malignant haematological disorders characterized by clonal proliferation of cells of the lymphoid line. Non-Hodgkin's lymphoma (NHL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM) are the most frequently encountered features of lymphoid hemopathies. Duriong the last 35 years the prevalence of these pathologies has increased in France but also in most industrialized countries. This increased can't be solely explained by demographic changes and improvements in diagnostic techniques. As a result, the involvement of environmental and professional factors is strongly suspected. Studies have shown that these diseases are associated with some professions or type of activity, including agricultural occupations, and other sectors such as agriculture, printing, woodworking. Some organic solvents and pesticides have been suspected of being risk factors of hematologic malignancies. Based on cohort studies and case-control studies, some of them have been identified by the International Cancer Research Center as associated with the occurrence of NHL with a sufficient or limited level of evidence. One of the difficulties encountered in the analysis of the literature has been the permanent evolution of the international classification of lymphoid hemopathies over the past 30 years. The old epidemiological studies are therefore difficult to interpret. Lymphoid hemopathies cover a range of different conditions, thus it is likely that carcinogens involved vary according to the type of hemopathy. Finally, environmental and occupational exposures to various chemicals and biological agents have evolved over time. The aim of this study is firstly to develop and validate a questionnaire to identify and quantify exposures to nuisances (substances and agents) suspected of being associated with the occurrence of NHL, MM and LLC. In a second time, this questionnaire will be used as a support for the realization of a subsequent case-control study to improve epidemiological knowledge on these diseases.

The present study aims at obtaining more in-depth information on how patients with chronic lymphocytic leukemia treated with idelalisib and rituximab react to treatment.
