Active clinical trials for "Leukemia, Lymphoid"

This is an expanded access program for eligible participants with a previously treated B-cell cancer who are ineligible for an ongoing pirtobrutinib clinical trial. The treating physician/investigator contacts Lilly when, based on their medical opinion, a patient meets the criteria for inclusion in the expanded access program.

This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.

Clinical validation of biomarkers determining resistance to BTK inhibition with Ibrutinib in Mantle Cell Lymphoma and Chronic Lymphocytic Leukaemia Stage 1.

This study provides for the collection of a series composed by patients with newly diagnosed of acute lymphoblastic leukemia in the period 1999-2011. This collection is carried out with retrospective investigation, through the review of paper and electronic records and data cards in large part already collected as part of study protocols "GIMEMA" or "BFM" or "NILG" approved by the Ethics Committee of Hospital. The purpose of data collection is to check with retrospective predictability of classical risk factors in relation to disease response, and overall survival of the event-free survival, to estimate the cumulative incidence of competitive events such as the emergence of disease, acute and chronic transplant, the transplant-related mortality and relapse of disease.

There are two regions in the adult brain that exhibit neuronal stem and progenitor cells, generating new neurons postnatally and throughout adulthood. One is the so called subventricular zone the other is the dentate gyrus of the hippocampus. Adult neurogenesis is a physiological process representing an important functional impact for certain brain areas, especially the hippocampus. The hippocampal formation plays an important role in long-term memory and spatial navigation. Inhibition of adult neurogenesis in mice by chemotherapy or radiation is followed by significant deficits in hippocampal memory functions while hippocampus-independent memory is unaffected. Clinical trials had shown that chemotherapy and brain radiation lead to cognitive dysfunction. However, the exact mechanisms underlying this phenomenon are still unidentified. The aim of our study is to investigate, whether the inhibition of adult neural stem cell proliferation in the hippocampus by intrathecal chemotherapy and/or cerebral radiation is responsible for treatment induced memory deficits. We will investigate patients suffering from acute lymphatic leukaemia (ALL) that receive prophylactic intrathecal chemotherapy and brain irradiation. The study represents a longitudinal investigation including a virtual "humanized" version of the morris-water-maze to test hippocampus dependent spatial memory, as well as MR-imaging for morphological (volumetry) and biochemical (spectroscopy) data.

Establishment of Acute Lymphocytic Leukemia Data Base in the Department of Oncology

Adult acute lymphoblastic leukemia treatment approaches relie on risk stratification, including cytogenetics. We want to study at diagnosis several blast cells parameters on frozen samples of GRAALL protocols enrolled patients: A CD45-DNA double staining analysed by flow cytometry will allow mesurement for each blastic clone of DNA ploidy, percentage of cells in S-phase, CD45 fluorescence index. The proteine P16 metabolic way, involved in cell cycle regulation, will be studied by Western Blot analysis. The comparison between these parameters, and main haematological data, will be followed by a prognostic analysis, based on blast corticosensibility in vivo, chimiosensibility, complete remission, and survival. Combination of the studied parameters will allow to appreciate a clonal diversity. This will help to predict, at diagnosis, high probability of resistance to treatment.

Lymphoproliferative disorders (LPD) are a major cause of morbidity and mortality in immunodeficient patients. There have been isolated case reports of patients with childhood ALL who developed LPD after ALL diagnosis, without undergoing stem cell transplantation, but data regarding such cases are limited. We propose here an international collaboration, to form a comprehensive database of children who developed LPD after diagnosis of acute lymphoblastic leukemia/lymphoma

This study proposes to investigate the association of nutritional status of a children assessed by body mass index (BMI), triceps skinfold thickness (TSFT), and mid upper arm circumference (MUAC), with body composition, measured by dual-energy X-ray absorptiometry (DEXA), in 60 children undergoing treatment of ALL at Unidad Nacional de Oncologia Pediatrica (UNOP), in Guatemala City, Guatemala. The study also aims to establish normative values of body composition in children residing in an LMIC by examining 160 healthy siblings of children under treatment, and to measure habitual physical activity in children with acute lymphoblastic leukemia (ALL) at diagnosis and during therapy.
