Chronic Lymphocytic Leukemia (CLL)

Background: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat. Pirtobrutinib is a drug approved to treat CLL and SLL after 2 previous treatments. Researchers want to know how this drug affects the immune system in those who have not yet started other treatments for CLL or SLL. Objective: To test pirtobrutinib as a first-line treatment for CLL or SLL. Eligibility: People aged 18 years and older with untreated CLL or SLL. Design: Participants will be screened. They will have a physical exam with blood tests. They will have imaging scans and tests of their heart function. They will have a lymph node biopsy: A large needle will be inserted into a lymph node to collect a small piece of tissue. Pirtobrutinib is a tablet taken by mouth. Participants will take 2 to 4 tablets daily in 4-week cycles. Participants will have clinic visits once every 4 weeks for the first 3 months. Then they will be seen once every 3 months. Imaging scans, lymph node biopsy, and other tests will be repeated at various study visits. A bone marrow biopsy (collection of soft tissue from inside a bone) may be done if there is no evidence of disease after 1 year of treatment with the study drug. Participants may opt to have cancer and immune cells collected from their blood. The cells will be used for research. Participants will have a clinic visit 1 month after their last dose of the study drug. Then they will have follow-up visits or phone calls every 6 to 12 months....

This study is focused on tracking the long-term health of patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) treated with a combination of two drugs, ibrutinib and venetoclax, as part of the original CAPTIVATE clinical trial. Purpose and Goals While new treatments have significantly improved survival for patients with CLL, the disease remains incurable and often requires multiple rounds of treatment over a person's life. The primary goal of this study is to understand what happens to patients after they have completed their initial (frontline) treatment with a combination of two drugs, ibrutinib and venetoclax, as part of the original CAPTIVATE clinical trial. Researchers specifically want to: * Identify the types and frequency of "second-line" treatments patients receive if their disease returns. * Assess the long-term safety and effectiveness of the initial ibrutinib and venetoclax treatment. * Study how the disease might become resistant to these treatments over time. Who Can Participate? The study is specifically for individuals who were previously enrolled in the original CAPTIVATE study. Only patients at participating medical centers who provide their informed consent can join. Study Methods and Procedures This is an observational study, meaning researchers will monitor patients' health during their routine medical care rather than testing a new, experimental treatment. Key aspects of the study include: * Long-Term Monitoring: Patients will be followed for up to 10 years. * Data Collection: Researchers will collect information on disease status, treatment history, new health issues (comorbidities), and survival. * Optional Testing: With additional consent, patients may provide blood samples every six months to check for "measurable residual disease" (MRD)-very small amounts of cancer cells that remain after treatment. * Genetic Analysis: If a patient's CLL progresses, researchers may analyze blood samples to look for specific genetic mutations that might explain why the treatment stopped working. Participation is entirely voluntary, and patients can choose to withdraw from the study or opt out of specific tests (like blood sampling) at any time without affecting their standard medical care.

This is a study for patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have previously received treatment with a BTK inhibitor (covalent and non-covalent) and a BCL-2 inhibitor. The main purpose of this study is to test if NX-5948 (bexobrutideg) works to treat patients with CLL/SLL. Participation could last up to 5 years, and possibly longer, if the disease does not progress.

Background: \- Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: \- To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: \- Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: * Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. * No treatment will be given as part of this protocol.

An observational study to assess the effectiveness, health economic-relevant costs and participant reported outcomes in participants with Chronic lymphocytic leukemia (CLL) receiving venetoclax as a monotherapy or in combination with rituximab, obinutuzumab, ibrutinib, or acalabrutinib as prescribed at the discretion of the physician and in accordance with local clinical practice and label.

Adult patients with chronic lymphocytic leukemia (CLL), splenic marginal-zone lymphoma (SMZL) and hairy cell leukemia (HCL) followed at participating clinical sites will be enrolled and undergo sampling of additional amount of blood during the blood draws performed as part of standard clinical care. The project aims to develop and validate innovative patient-derived 3D bioprinted models that faithfully reproduce the key microenvironments of lymphoid tissues, enabling a more physiologically relevant study of mature B-cell malignancies.

Background: Bruton s tyrosine kinase inhibitors (BTKi) are used to treat a form of leukemia. But taking BTKi can also increase a person s risk of developing an abnormal heart rhythm. This can cause sudden death. In this natural history study, researchers want to learn how BTKi affects the heart. Objective: To identify and monitor the effects of BTKi on the heart. Eligibility: People aged 18 and older currently receiving or planning to receive BTKi or venetoclax. Design: Participants who have not yet started BTKi will have 2 required clinic visits: 1 before they start taking BTKi, and 1 about 6 months later. Participants who are already taking BTKi will have 1 required visit. Participants will undergo multiple tests: A physical exam, including collection of blood and saliva. A test that measures heart activity via stickers placed on the chest. A test that uses sound waves to capture images of the heart. An exercise stress test that monitors heart activity and blood pressure while the participant works on a treadmill or stationary bike. Sound wave images of the heart may also be taken while the participant exercises. Stress magnetic resonance imaging (MRI) may be done in place of an exercise test. Participants will lie on a table that slides into a tube. They will be given drugs to stress the heart while images are taken. Participants may wear a device to monitor their heart at home. Participants may have repeat visits if they develop heart symptoms or if they need to stop taking BTKi. They will have follow-up phone calls each year for up to 3 years.

This study will evaluate the efficacy and safety of finite-duration acalabrutinib plus venetoclax therapy in patients with relapsed CLL or SLL, and have previously responded to first line (1L) cBTKi + BCL2i therapy (± obinutuzumab) and maintained a response for at least two years post-treatment.

This is a retrospective observational research study to describe the characteristics and real-world clinical outcomes of patients with chronic lymphocytic leukaemia receiving acalabrutinib in the United Kingdom (the EPIC study). Physicians treating chronic lymphocytic leukaemia patients with acalabrutinib, where the patients started treatment as part of the acalabrutinib Early Access Programme (EAP), will be invited to recruit patients. Clinical data will be extracted from the patients' clinical records in line with local laws. Data from this study will provide UK-specific real-world data on patients who were started on acalabrutinib as part of the UK acalabrutinib EAP.

The purpose of this study is to determine the rate of minimum residual disease (MRD) negative response (i.e. the rate of no evidence of disease) of the study drugs, zanubrutinib, obinutuzumab, and venetoclax, given in combination as a treatment for CLL and/or SLL.

The study aims to improve our understanding of how quality of life, fatigue, and symptoms change over 2 years when participants are treated for chronic lymphocytic leukemia or small lymphocytic lymphoma. We will compare two types of treatment to help future patients with chronic lymphocytic leukemia or small lymphocytic lymphoma know what to anticipate.

This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-2127 in patients with advanced B-cell malignancies.

This is a Phase I/II, interventional, single-arm, open-label, treatment study designed to evaluate the safety and efficacy of Interleukin-7 and Interleukin-15 (IL-7/IL-15) manufactured chimeric antigen receptor (CAR)-20/19-T cells as well as the feasibility of a flexible manufacturing schema in adult patients with B cell malignancies that have failed prior therapies.

Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

This is an expanded access program (EAP) for eligible participants. This program is designed to provide access to Venetoclax prior to approval by the local regulatory agency. Availability will depend on territory eligibility. A medical doctor must decide whether the potential benefit outweighs the risk of receiving an investigational therapy based on the individual patient's medical history and program eligibility criteria.

Physical exercise, particularly strength training, has become an effective strategy to improve physical function, muscle mass, and quality of life in cancer patients. However, the biological mechanisms underlying these benefits remain poorly understood, especially during active treatment. The PEPOH project (Precision physical Exercise for Personalized Onco-Hematology) proposes a single-center clinical trial conducted at the Fundación del Instituto de Investigación Biomédica de Salamanca (FIBSAL) including five different patient cohorts: lung, colorectal (CRC), and breast cancer, chronic lymphocytic leukemia, and multiple myeloma. Participants will be randomly assigned to either an in-person intervention group, performing a supervised strength training program twice a week for 12 weeks combined with a home-based exercise program, or a control group performing only the home-based program. Biological samples will be collected before and after the intervention for multi-dimensional characterization (Genomics, Transcriptomics, Proteomics and Metabolomics) and systematic integration with parameters of functional capacity, quality of life, psychological well-being, frailty, and body composition. The main objective of the project is to determine biological parameters associated with strength exercise and their relationship with clinical parameters related to prognosis, therapy response and survival. This multi-dimensional approach will enable the detection of exercise adaptation biomarkers and generate knowledge about the mechanisms linking exercise with improved health outcomes in individuals with cancer. PEPOH will contribute to biomedical science and will enhance the comprehensive care of oncohematologic patients by integrating multi-omic and clinical data into a precision exercise model. This project will also contribute to society by offering a cost-effective, safe, and transferable intervention, which increases the overall quality of life.

This study is being done to test the effectiveness of zanubrutinib in combination with venetoclax in participants with previously treated chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
