Active clinical trials for "Leukemia"

This study is open to all patients with a diagnosis of acute promyelocytic leukemia (APL) who are PCR positive for the PML-RARα transcript or rarer retinoid sensitive subtypes (i.e. NPM-RAR-alpha, NuMA-RARalpha) and less than 21 years of age (for AIEOP, see appendix A).

Patients with relapse of acute leukemia often only receive supportive therapy. Our hypothesis is that a combination therapy can stabilize the disease for patients with early relapse after allogeneic stem cell transplantation. The investigators will combine 5-azacitidine 100 mg daily subcutaneously (days 1-3), valproic acid (continuous therapy from day 1), All-trans retinoic acid (days 1-14) and hydroxurea (continuous treatment from day 15 of first cycle. Azacitidine and ATRA can be repeated with 5 weeks intervals, donor leukocyte infusions on day 10 is allowed from the second cycle.

The main objective of this work is to conduct a clinical study for the development and application of a vaccine with autologous dendritic cells submitted to electroporation with Wilm's tumor 1 (WT1) messenger ribonucleic acid (mRNA), as an adjuvant treatment of high-risk Myelodysplastic Syndromes and Acute Myeloid Leukemia, aiming to delay the progression of the disease or its relapse and increase overall and event-free survival.

The present study was conducted to assess the population pharmacokinetics of 6-mercaptopurine (6-MP) in Pediatric Acute Lymphoblastic Leukemia (ALL) and genetic polymorphisms

Acute leukemias are a heterogeneous group of malignancies characterized by the abnormal proliferation of a cell clone in the bone marrow, having as origin lymphocytic or myeloid lineage. The repertoire of mutations that determine the leukemic transformation, complex and variable depending on the tumor type and progression of the disease, combined in the same cell of balanced and unbalanced chromosomal aberrations, point mutations and epigenetic abnormalities. The project presented here is part of a comprehensive approach to diagnosis of hematologic malignancies of children. Using comparative genomic hybridization on microarray (or array- CGH) and transcriptome analysis by microarray, two innovative techniques for a comprehensive analysis of the genome and transcriptome , offer new perspectives identifying molecular defects . These techniques provide new elements in the identification of acute leukemia at diagnosis may identify new prognostic factors to optimize the care of patients. This project involves both the Department of Medical Genetics (Prof. N. LEVY ) regarding the identification of genomic abnormalities associated with childhood leukemia , the Laboratory of Hematology of the Hospital de la Timone ( Prof. Pierre Morange ) in terms of the phenotypic characterization of tumor cells, and the Onco - Hematology Pediatric Department (Prof. Michel Gerard ) which provides diagnosis, treatment , monitoring and the bone marrow of children with hematologic malignancies . The following project is mainly focused on the identification of genomic abnormalities (deletions and duplications) and abnormalities in gene expression to identify a genetic profile ensuring a better classification within the different groups risk . The project we propose is centered on the identification of genomic abnormalities , changing the number of copies of certain regions of the genome or determining loss of heterozygosity , and the identification of changes in the level of gene expression by using two analytical techniques, comparative genomic hybridization on microarray (or array- CGH) and expression studies with microarrays . The data generated will , for the identification of " molecular signatures " , the classification of patients according to prognosis , variations in treatment response and survival. The originality of this project lies in the use of these new tools in the diagnosis of hematological malignancies in children. This pilot study will be conducted with commercial Affymetrix , will develop the chips ' processing' , dedicated , enriched probes corresponding to genes involved in leukemogenesis , with high discriminatory power in identifying these signatures. The data published in the specialized literature from the study of large series of patients show that microarrays provide important information for the diagnosis and therapeutic management of patients. It is for this reason that in the end we hope to integrate these analyzes in routine diagnosis to complement other analyzes ( phenotyping , identification of fusion genes and sequencing) in order to further characterize the abnormal cells leukemia and establish an " identity card of leukemia .

Usually Chronic lymphocytic leukemia (CLL) is a disease of the elderly patients. However, the diagnosis in young patients become more frequently with poor prognosis. The identification of new prognostic factors permits early determination of the high risk population and provide them the therapeutic intensification. Allogeneic transplantation of hematopoietic stem cells transplantation (AHSCT) allows to long-term remission and in some cases complete and definitive eradication of the disease. After chemotherapy or antibodies, the Minimal Residual Disease (MRD) negativity is associated with better disease-free survival. MRD negativity occurs in some patients with the appearance of GVHD, stopping the immunosuppression or after donor lymphocyte injection (DLI). The negativity of MRD in the first year post-transplant is correlated with better progression-free survival or overall survival (Dreger 2010, Farina 2009, Caballero 2005, Algrin, 2011). So, MRD negativity may be an objective after AHSCT. The aim of this prospective study is to evaluate a standardized preemptive immunointervention of post-allograft immunosuppressive therapy modulation and DLI administration according to MRD level. The objective is to obtain MRD negativity at 12 months after AHSCT.

This trial investigates stem cell transplants from partially mismatched donors in patients with blood and bone marrow cancers. The trial will test two kinds of transplants - a full intensity transplant using a high dose of radiotherapy and chemotherapy, and a reduced intensity transplant with lower doses of chemotherapy and radiotherapy. Patients will be entered for the treatment pathway that is most appropriate for their level of health and fitness

The present study aims at verifying the state of the art in what this illness concerns and at organizing a centralized samples analysis.

The clinical study of CART19 Cells treatment for MRD of B Cell Malignancies and then auto-HSCT

This pilot trial studies the impact of genetic information on developing liver damage caused by asparaginase in participants with newly diagnosed acute lymphoblastic leukemia. Testing saliva samples may help doctors find certain genetic markers that may predict whether participants will tolerate asparaginase, which is given as part of clinical care for acute lymphoblastic leukemia.
