Active clinical trials for "Leukemia"

Asparaginase is an important drug i the treatment of childhood leukaemia. The aim of this project is to study the pharmacokinetics, pharmacodynamics and antibody development and hypersensitivity reactions during prolonged PEG-asparaginase treatment. Study part 1) Asparaginase pharmacokinetics and pharmacodynamics during prolonged PEG-asparaginase treatment: A NOPHO ALL-2008 study Study part 2) Asparagine depletion in cerebrospinal fluid: A NOPHO ALL-2008 study Study part 3) A characterization of PEG-asparaginase hypersensitivity in children treated according to the NOPHO ALL 2008 protocol Perspectives: New knowledge about PEG-asparaginase treatment regarding dosing, dosing interval, adverse effects and EFS, which may lead to improved future therapy Patients: Children diagnosed with acute lymphoblastic leukaemia in the Nordic Countries

In this observational single-center cohort study, metagenomic Next-Generation Sequencing (mNGS) will be used to investigate the features and changes of gut microbiota in acute myeloid leukemia (AML) patients during the treatment of two different induction therapy regimens [standard intensive chemotherapy (7+3) or bcl-2 inhibitor-based targeted therapy].

To see if there is a relationship between the level of LIF in IUGR fetuses and compared to the level of LIF in AGA fetuses

The investigators will evaluate the outcomes of allogeneic stem cell transplantation which is the only curative treatment modality in the patients with chronic myeloid leukemia after failing tyrosine kinase inhibitor therapy. However, any update was not reported on the transplant outcomes in the patients failed TKI therapy, thus necessitating update of this data. Also, the European Group for Blood and Marrow Transplantation (EBMT) risk score is still of value, but insufficient numbers of patients have been transplanted in recent years and after TKI therapy to allow a robust reanalysis. Our study hypothesis is that allogeneic SCT treatment modality can rescue CML patients who failed TKI therapy due to resistance or to intolerance with improved survival and long-term outcomes. Also, another hypothesis will be examined if the EBMT risk score proposed pre-imatinib era can reproduce similar prognostic risk stratification of long-term outcomes in the patients treated with TKI.

The main objective of this observational survey is to estimate the incidence, the typology, and the evolution of patients with acute myelobalstic leukemia, aged more than 60 years old. In this age group (aged more than 60y), three groups of patients with very different response rates and late outcome can be delineated with specific standard chemotherapy.

Whether Idarubicin can overcomes multidrug resistant 1 induced chemoresistance with higher induction remission rate than daunorubicin in de novo acute myeloid leukemia patients.Whether induction therapy with IA regimen has a higher remission quality with AML patients than that of DA regimen in high MDR1 expression AML patients.

Chronic lymphocytic leukemia is the most common type of chronic leukemia, accounting for approximately 40% of all leukemias and mainly affecting older individuals. As it has a highly variable clinical course, identification of molecular and biological prognostic markers has provided new insights into the risk stratification of patients with chronic lymphocytic leukemia.

Acute lymphoblastic leukemia , also known as acute lymphocytic leukemia, characterized by the overproduction and accumulation of cancerous, immature white blood cells, known as lymphoblasts, causing damage and death by inhibiting the production of normal cells (such as red and white blood cells and platelets) in the bone marrow and by spreading (infiltrating) to other organs. Acute lymphoblastic leukemia is most common in childhood, with a peak incidence at 2-5 years of age and another peak in old age.

Gemtuzumab Ozogamicin/Mylotarg® (GO) is a conjugate of a derivative of calicheamicin a potent antitumor anthracycline antibiotic linked to a recombinant humanized antibody against the CD33 antigen. Pivotal phase 2 study in relapsed AML adult patients used GO 9 mg/m2 as a monotherapy on days 1 and 14, and showed a 30% response rate with half CR and CRp (CR with incomplete platelets recovery). Four randomized studies, 3 in adults and 1 in children, performed in patients with non-previously treated AML tested the addition of lower doses of GO ( 3mg or 6 mg/m2) to standard induction chemotherapy and showed benefit on survival endpoints. Results from these studies were available in 2011 in adults and 2014 in children. In 2010 the french health agency (ANSM) opened a compassionate patient named program (authorization for temporary utilization (ATU) program) of GO in relapsed/refractory AML patients. Patients were orally informed about the status of the GO. From 2010 to 2012 it was recommended to use GO as a monotherapy at a dose of 9mg/m2 on days 1 and 14 according to the protocol used in pivotal phase 2 study. After 2012 it was recommended by the health authority to use GO at the dose of 3 or 6 mg/m2 in addition to chemotherapy regarding the toxicity of higher dose given once. From 2010 to 2015 more than 500 AML patients have been included in this ATU program. The main objective of the study presented here is to assess the efficacy and safety of GO 3 or 6 mg/m2 (single dose or fractionated GO) given in as treatment of relapsed/refractory AML in adult patients. The coordinator choose to collect the data from centers that included 10 patients or more from January 2012 to December 2015. This represents approximately 420 patients from 33 hematology departments.

The registry aims to compare the two first-line available treatment approaches in non-high-risk APL patients aged ≤ 70 years - ATRA plus chemotherapy and ATRA plus ATO - in terms of practitioner's choice between the two options, clinical effectiveness and cost-effectiveness, long-term outcome, and short- and long-term toxic effects.
