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

This multi-center, prospective, observational study will describe the management of relapsing or refractory chronic lymphocytic leukemia (CLL) patients. Data will be collected for 2 years.

The purpose of this registry is to record information on therapy reality of malignant lymphatic systemic diseases by office-based haematologists in Germany.

Evaluation of safety profile and tolerability of MabThera (rituximab) in combination with chemotherapy (fludarabine and cyclophosphamide) in the treatment of Chronic Lymphocytic Leukemia (CLL).

This study is intended for Chronic Lymphocytic Leukemia patients who have already undergone a first or second treatment with drugs named bendamustine and rituximab. It will observe the results of this treatment and evaluate its efficacy and side effects.

Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults in Western countries; it is stratified as a subtype of indolent lymphoid malignancy with a long but slowly progressive nature history. However, the clinical course of CLL actually varies widely. Thus, many clinical and molecular features have been identified for outcome predictions. The accurate predictions of prognosis through those factors help for the decision making on the treatment, i.e. to treat patients of high risk of early progression or poor overall survival (OS) with alternative or investigational therapies, while to avoid unnecessary over-treatment for low-risk patients. CLL is much less prevalent in Eastern countries; presently, most available data on CLL are derived mainly from Western countries. However, a previous report concerning the epidemiology of CLL in Taiwan revealed a drastic increase in the age-adjusted incidence of CLL, a trend not found in Western countries where the incidence rate of CLL remained steadily stable over time. In addition to this epidemiological difference, a population-based analysis has found the overall outcome of CLL, estimated by relative survivals, is steadily much poorer in Taiwanese patients than in US Caucasians. In another report about the cytogenetic profiles in a small cohort of CLL patients in Taiwan, a novel cytogenetic abnormality was found to correlate with poorer outcomes. These reports suggest the existence of ethnic differences in the disease natures of CLL between the East and the West. To delineate the possible underlying racial differences, especially in the molecular prognostic profiles that might underlie the outcome disparity between Taiwanese and western CLL patients, a comprehensive surveillance of the molecular profiles for CLL in Taiwan is of importance. In this study, we are going to enroll around 250 CLL patients; their clinical parameters will be recorded, their blood samples will be collected for a panel of molecular and cytogenetic factor studies. The molecular markers to be tested in this project include (but not limited to) cytogenetic abnormalities by fluorescent-in-situ hybridization (FISH), immunoglobulin heavy chain variable region (IGHV) hypermutation status, gene mutations for Notch1, SF3B1, p53, MyD88, and BIRC3, and the expressions for ZAP70 and stem cell factor (SCF). These proposed markers include not only the conventional prognostic markers derived from Western studies, and also some novel explorations from our preliminary results, such as SCF and trisomy 3. Through this study, a comprehensive profile of CLL in Taiwan will be established to identify the characteristics of CLL in Taiwanese patients and to address the underlying factors of ethnic differences in the disease nature and outcomes of this disease.

The purpose of this study is collect and evaluate the clinical experience reached in Italy on the use of bendamustine alone or combined with rituximab as treatment of patients with relapsed or refractory chronic lymphoproliferative disorders.

This study seeks to assess the effectiveness and safety of venetoclax in patients with relapsed and refractory chronic lymphocytic leukemia (CLL) in a real-world setting across clinical practice in the Russian Federation.

Historically, the best results of allogeneic SCT have been obtained when the stem cell donor is a human leukocyte antigen (HLA)-matched sibling, however, this is only available for approximately 30 percent of patients in need for SCT. Alternative donor sources include matched unrelated donor utilizing the donor registry, cord blood transplant and mismatched donor transplant. A human leukocyte antigen (HLA)-haploidentical donor is one who shares, by common inheritance, exactly one HLA haplotype with the recipient, and includes the biologic parents, biologic children and full or half siblings. There is strong body of evidence supporting the use of haplo-SCT in patient who lack a matched sibling or unrelated donor with high rates of successful engraftment, effective Graft Versus Host Disease (GVHD) control and favorable outcomes comparative to those seen using other allograft sources, including HLA-matched sibling SCT. Furthermore, it provides a cost-efficient donor option in a timely manner especially for patients who need to proceed quickly to transplant due to concern of disease relapse/progression.

This multi-site study will enroll approximately 100 CLL patients across 5 cancer institutions. The aim of the project is to ensure hematology care teams that are participating in new value-based reimbursement models have an accurate understanding of the evidence and roles of new therapies for CLL and best practice supportive care protocols to proactively assess, monitor, and manage symptoms to promote successful clinical outcomes. Hematology teams at seven health systems across the U.S. will be given online clinical training on the latest evidence for treatment planning in CLL along with best supportive care practices for patients on novel CLL treatments, prior to using Carevive's patient engagement software. Once training is complete, the Carevive software will be employed in the clinic whereby CLL patients will use the Carevive patient portal to report any symptoms at and in between clinic visits. Patients will be given a user name and password to a web-based portal for 24/7 reporting of symptoms experienced. Patient-reported and clinical data will be processed by the Carevive rules engine technology to generate evidence-based supportive care plans providing patients with direction regarding self-management strategies, care coordination for relevant cancer center services, and direction on when to go to the emergency department (ED) or call their hematologist based on their institution's protocol. For patients who require ongoing and routine monitoring, such supportive care recommendations will be included in supportive care plans generated at the clinic visit. On the visits subsequent to the delivery of the care plan, patients will report on the perceived effectiveness of the intervention (or barriers to non-adherence to the intervention). Patients and clinicians will assess symptom severity at each visit for a 16-week period and both data sets will be stored and analyzed for research purposes.

This two-year pilot study will test whether a one-page "Jumpstart Form" will affect goals-of-care discussions in the hospital. This form will be provided to clinicians and will include patient-specific information about preferences for goals-of-care communication and for care, as well as tips to improve this communication. Jumpstart forms will also be provided to patients or, if they are unable to communicate, their surrogates/family members. The information on the form will be obtained from questionnaires. The form is tailored to help patients and surrogates talk with clinicians about goals of care. This study is based on a successful application of Jumpstart Form in the outpatient clinic setting.
