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

This observational study will assess the therapeutic efficiency, treatment schedules, handling procedures, and the safety profile of rituximab in routine care in participants with CLL.

Purpose: The involvement of Natural Killer cells (NK) in the efficiency of the treatment in lymphoma and the beginning of new therapies based on function and activation of NK, justify an improvement of knowledge about the status of the population of NK (number, function, genic expression) in Chronic Lymphocytic Leukemia (CLL).

The primary objective of this study is to evaluate the effectiveness of idelalisib and rituximab in adults with chronic lymphocytic leukaemia (CLL) in a real world setting

This observational retrospective study will enroll at least 158 patients affected by Chronic Lymphoid Leukemia (CLL) with previous HBV exposure (HBsAg negative, anti-HBc positive with or without anti-HBs) treated with Ibrutinib single agent according to the IWCLL criteria 2008. Patients will be divided into two cohorts, one encompassing patients who received lamivudine and the second one including patients who received no prophylaxis. Each patient will be observed for one year from the first administration of Ibrutinib.

This observational study aims to study the effectiveness and safety of Obinutuzumab in common clinical practice settings in Argentina. The study population comprises all patients with chronic lymphocytic leukemia (CLL) that have received the indication for treatment with Obinutuzumab as per routine clinical practice.

Broadly speaking, the goal of this study is to better understand the influence of chemotherapy treatment on the cognitive and neural mechanisms underlying human behavior. Extant literature lacks diversity in studied cancer populations and treatment protocols, and provides limited understanding of the cognitive abilities that are impaired by chemotherapy. To overcome these limitations, this study will employ a sophisticated battery of tests on an understudied cancer population. Eligible participants will either be patients diagnosed with hematological malignancy (HM) or demographically matched healthy control patients. After HM diagnosis and treatment protocols have been established, patients will be inducted into the longitudinal study comprised of three visits: 1) after diagnosis but prior to chemotherapy treatment (baseline), 2) after one treatment cycle (one month post-baseline), and 3) after three treatment cycles (three months post-baseline). Patients will undergo a test battery designed to measure specific behavioral and neural mechanisms of attention; tests will either be computer-based cognitive tasks or simulated driving tests that immerse patients into virtual driving scenarios. During each test, EEG will be concurrently measured through non-invasive scalp electrophysiology recordings; EEG recordings will reveal underlying neural mechanisms affected by chemotherapy. Additionally, neuropsychological tests of vision, attention, and memory will be administered, as well as questionnaires to evaluate health, mobility, and life space. Finally, blood samples will be collected to examine levels of circulating inflammation-specific proteins typically present in cancer patients. This study will allow us to better understand the mechanisms through which chemotherapy influences cognitive performance. Results from this study will influence the administration of chemotherapy treatments so that patients can continue to receive the highest medical care while maintaining optimal cognitive abilities and quality of life.

This study will collect real-world safety and efficacy data from Japanese relapse/refractory chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) participants treated with venetoclax.

This is a retrospective observational study aimed at describing the characteristics and outcome of CLL patients included in the NPP in Italy in a period of time ranging from the start of the NPP until November, 30th 2014. A longitudinal survey will be carried out by collecting data of patients who received at least 1 dose of Ibrutinib. All patients will be observed for at least 12 months from the treatment start.

This is a post-authorization, retrospective multicentre observational nationwide study (PAS-OD). It will be conducted by reviewing medical records and database of patients who participated in the validation of the psychometric properties of the GAH study (CEL-GAH-2011-01). In all cases, only data prior to the start date of the study will be collected to ensure its retrospective nature, thereby reflecting routine clinical practice and non-interference in the physician's clinical practice

Background: Chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and mantle cell lymphoma (MCL) are types of cancers in which there are too many abnormal lymphocytes (a type of white blood cell). Monoclonal B-cell lymphocytosis (MBL) is a condition in which the individual has a larger than normal number of lymphocytes. Individuals with CLL, SLL, MBL, and MCL may survive for many years without the need for treatment, but there is an apparent correlation between cell birth rates and disease activity. By studying the birth and death rates of lymphocytes, researchers hope to identify individuals who are at risk for worsening disease. Heavy water is similar in structure to regular water, but it has two deuterium atoms instead of two hydrogen atoms. Deuterium has one more neutron than hydrogen, which is what makes heavy water heavy. Heavy water is not radioactive, looks and tastes like regular water, and has no known harmful effects at research-level doses. When a small amount of heavy water is consumed daily, newly produced blood cells are labeled (tagged), which allows researchers to track cell growth and to measure the birth and death rates of CLL, SLL, MBL, MCL or normal lymphocytes. Objectives: - To study the birth and death rates of lymphocytes from individuals with MBL, CLL/SLL, and MCL, compared with lymphocytes from healthy volunteers. Eligibility: Individuals at least 18 years of age who have been diagnosed with MBL, CLL, SLL, or MCL, but who have not been taking certain agents (Viagra, Levitra, Cialis, or other PDE-inhibitors, prednisone, cyclosporin-A, rapamycin, or other immunosuppressive agents, more than 2 cups of green tea daily, or Celebrex) for 4 weeks prior to enrollment in the study. Healthy volunteers at least 18 years of age, but who have not been taking certain agents (Viagra, Levitra, Cialis, or other PDE-inhibitors, prednisone, cyclosporin-A, rapamycin, or other immunosuppressive agents, more than 2 cups of green tea daily, or Celebrex)for 4 weeks prior to enrollment in the study. Design: Participants will be screened with a medical history, physical examination, and initial blood tests. Other tests may be administered to the individuals with cancer, as required by the study researchers. All participants will drink regular doses of heavy water daily for a total of 4 weeks (labeling period). There is an optional 6-month follow-up or wash-out period during which no additional heavy water will be consumed. Blood samples will be collected weekly during the labeling period, and a bone marrow biopsy will be obtained where possible. Individuals with cancer may also have a lymph node biopsy during this part of the study. Additional blood samples may be collected during the optional wash-out phase of the study to determine the rate at which cancer cells disappear. Treatment is not provided as part of this protocol.
