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

The purpose of this study is to evaluate the efficacy and safety of ibrutinib + venetoclax (I+V) and ibrutinib monotherapy regimens in which dosing of ibrutinib is either proactively reduced or reactively modified in response to adverse events (AEs).

Phase 1 study comprised of open-label, dose escalation and expansion cohort study of P-CD19CD20-ALLO1 allogeneic T stem cell memory (Tscm) CAR-T cells in subjects with relapsed/refractory B cell malignancies

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.

This study aims to evaluate the safety and efficacy of humanized Anti-CD19 Chimeric Antigen Receptor-T cell (CAR19T2 T cell) in children with refractory/relapsed B-cell acute lymphoblastic leukemia/lymphoma.

This study will enroll patients initiating Bruton Tyrosine Kinase (BTK) inhibitors without history of documented arrhythmia while on therapy using the Medtronic LINQ-2 insertable cardiac monitor (ILR). The incidence of new onset atrial fibrillation (AF) and other arrhythmia will be determined. Actions taken in response to device detected arrhythmia will be recorded.

Chronic lymphocytic leukemia (CLL) is the most frequent form of leukemia in the Western World. The disease is characterized by the accumulation and proliferation of mature, monoclonal, CD5+ B-cells with specific immunophenotype in the peripheral blood (above 5x109/L), bone marrow and secondary lymphoid organs. Small lymphocytic leukemia (SLL) is characterized by similar tumor cells but without increased lymphocyte count. The management of these patients have considerably changed over the last decade. Indeed, beyond chemo-immunotherapy, multiple targeted therapies have been approved on the basis of phase 2 and randomized phase 3 clinical trials and have subsequently been used in daily practice. The management of patients with SLL is similar to that of those with CLL. In addition to therapeutic advances, the advent of new sequencing technologies has also identified CLL genetic features that are now being incorporated in patient routine evaluation. We here propose to set a large-scale prospective and non-interventional study including patients with symptomatic CLL/SLL with the aim to evaluate the real-world clinical management of these patients and to identify the impact of treatments and therapeutic trajectories on long-term outcome.

Retention rate of acalabrutinib in a non-interventional setting. This is a prospective, multicentre, non-interventional study to collect real-world data on retention rates of CLL patients prescribed with acalabrutinib in Germany.

The goal of CICERO is to investigate the clinical outcome with a particular focus on prospective data on safety using acalabrutinib (+/- obinutuzumab) in CLL patients receiving co-medication with DOACs (edoxaban, rivaroxaban, dabigatran, apixaban) irrespective of treatment line.

This pilot study examines the safety and efficacy of anti-CD19 CAR T cells manufactured on-site in children and young adults with relapsed or refractory CD19+ B cell acute lymphoblastic leukemia or CD19+ B cell non Hodgkin lymphoma. Patients will undergo screening, leukapheresis (cell collection), lymphodepleting chemotherapy with fludarabine and cyclophosphamide, followed by the anti-CD19 CAR T cell infusion. The lymphodepleting chemotherapy is administered over four days IV to prepare the body for the CAR T cells. The anti-CD19 CAR-T cells are infused between 2-14 days after the last dose of chemotherapy. This study is designed for participants to begin lymphodepleting chemotherapy during the CAR T cell manufacture and receive a fresh cell infusion on the day that manufacturing is complete. Some patients may need more time in between the cell collection and the CAR T cell infusion, therefore, the cells may be manufactured and frozen prior to administration. Patients will be followed for a year after the cell infusion on the study and for up to 15 years to monitor for potential long term side effects of cell therapy.

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. 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.
