Active clinical trials for "Leukemia, Lymphoid"

The purpose of the study is to investigate whether the combination of obinutuzumab and ibrutinib (administered up to 840 mg per day) might be useful for the treatment of CLL or SLL that is not responding or no longer responding to treatment with ibrutinib alone. The study will evaluate whether this regimen can reduce the amount of cancerous cells in the body. Subjects will be treated with ibrutinib at a dose of up to 840 mg a day by mouth, as well as obinutuzumab infusions. Although both of these agents are approved by the FDA for the treatment of CLL or SLL, the combination and the dosing schedule of ibrutinib are considered experimental.

The application of positron emission tomography with lymphoproliferative diseases today provides diagnostic and therapeutic information of major importance , especially in terms of speed and quality of response to treatment. The radiopharmaceutical used in clinical practice for this exam is fluorodeoxyglucose 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose ([18F]-FDG) . However , the uptake of this tracer is not elective in lymphoid tissues , with a lack of specificity. In addition , the avidity of this tracer is unequal according to the histological subtype (lack of sensitivity). To try to improve the results of this clinical exploration of lymphoid malignancies, the investigators developed a new radiopharmaceutical ( [18F] - fludarabine ). The idea of transforming the fludarabine radiopharmaceutical is based on the existence of a fluorine atom in the molecule and the pharmacokinetic characteristics of this drug. The [18F]-Fludarabine is a new radiopharmaceutical reproducing the same dosage formulation of fludarabine , a drug used for the treatment of certain types of lymphoproliferative diseases, especially those where the tumor cells have a low proliferation kinetics . This drug is used in therapy in particular pharmacokinetic effect for a high affinity for the lymphoid tissue . Preclinical results on normal and lymphoma xenograft -bearing mice showed a specificity restricted to lymphoid tissue fixation with [18F]-Fludarabine compared with [18F]-FDG . Based on these encouraging results , the investigators propose in this work to explore the Dosimetry and Biodistribution of [18F] - Fludarabine in human lymphoproliferative diseases : 1)A first group of patients with non-Hodgkin's large cell lymphomas in which it already has a wealth of experience in exploration [18F]-FDG, and 2) a second group of patients with chronic lymphocytic leukemia, where the results of the exploration [18F]-FDG are considered disappointing and did not, for this reason, experienced clinical development.

The purpose of this study is to test the safety of Erwinia Chrysanthemi asparaginase when used alone and together with chemotherapy and find out what effects, if any, it has on people.

Gene transfer is a process in which the DNA (genetic material) of certain cells is changed. In this study, gene transfer will be performed on a type of white blood cell (called T cells) to recognize leukemia cells in the same person the T cells were collected from. The goal of this clinical research study is to learn if it is safe to give these genetically-changed T cells back to patients with CLL/SLL. Researchers also want to learn if these cells can help to attack CLL/SLL cells.

The goal of this study is to find a safe dose of sirolimus that can be used with a standard dose of L-asparaginase. To find the safe dose, the investigators will give the first patient a very small dose of sirolimus (smaller than the dose used in organ transplant children) and the standard dose of L-asparaginase. The investigators will then look for side effects. If side effects develop, the investigators will decrease the dose of sirolimus. If they do not, the investigators will increase the dose of sirolimus in the next patient on the study. The investigators will continue this method until fewer than one-third of patients have a side effect that would require stopping the drug or changing the dose. The investigators plan to enroll up to 15 children with relapsed ALL. The enrolled patients must have recovered from other treatment before starting this study. Also, they cannot have severe side effects from their earlier therapy that will possibly make these drugs less safe. The investigators will collect information on whether these drugs help to cure the ALL, but the purpose will be to find a dose of sirolimus that does not cause too many side effects when combined with L-asparaginase. This will be explained to the families and they will sign a written consent. The patients will provide either verbal or written assent when appropriate.

This is a Phase 2b, open-label, multicenter, global study assessing the safety and efficacy of ABT-263 in subjects with B-cell CLL who have failed at least one prior fludarabine-containing regimen.

This research study aims to address the limited understanding of the challenges faced by specific demographic groups of chronic lymphocytic leukemia patients in their participation in clinical trials. This trial will scrutinize the experiences of patients diagnosed with chronic lymphocytic leukemia as they take part in a separate medical intervention clinical trial. The focus will be on tracking the rates of completion and withdrawal among these individuals. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future chronic lymphocytic leukemia patients.

This is a multicenter, prospective, observational cohort study to comprehensively and longitudinally evaluate and characterizes the cardiovascular events with CLL patients who are initiating treatment with a Bruton's tyrosine kinase (BTK) inhibitor ibrutinib or acalabrutinib.

The goal of this observational study is to assess in the cohort of CLL patients enrolled in the front-line GIMEMA LLC1114 study who discontinued ibrutinib the time to subsequent treatment. The main question it aims to answer is: • The 12 and 24-month TTNT measured from the time of ibrutinib discontinuation due to reasons other than CLL progression, Richter syndrome, malignancy or death, or lost to the follow-up. Participants will be observed for the duration of the study.

This study investigates families with at least two cases of B-cell lymphoproliferative disorders (LPD), and evaluates the prevalence of LPD in families, the relationship between medical history, genetic factors, and the risk of familial LPD, and various clinical outcomes for these families in a multiethnic population of Jews and Arabs in Israel.
