Active clinical trials for "Leukemia"

Hairy-cell leukemia is a rare and indolent lymphoid disorder, representing 2% of all cases of lymphoid leukemias. Treatment of hairy-cell leukemia relies mainly on the purine analogs, cladribine and pentostatin, which have shown similar efficacy and constitute the gold standard of care either as front-line therapy or for relapsed patients. However, despite the remarkable response rates obtained with purine analogs therapy, some patients will eventually relapse and the efficacy of these agents seems to decrease at each line of treatment. The addition of new molecules to purine analogs may improve the response rates and prevent relapse. Rituximab is a chimeric IgG1 kappa-type monoclonal antibody directed against the CD20 molecule. It was first used in relapsed patients with hairy-cell leukemia more than 10 years ago and several series of patients treated with rituximab as monotherapy were published in the following decade, reporting response rates ranging from 25% to 80%.

Febrile neutropenia (FN) is a common and serious side effect of chemotherapy. Current management of FN is expensive and may induce side effects. Honey is a natural substance produced by honeybees. It possesses antioxidant, antimicrobial and anticancer effects. In addition, honey is not expensive. The aim of this study was to evaluate the effects of 12-week honey consumption on children with acute lymphoblastic leukemia (ALL) particularly with regards of FN episodes. This randomized crossover clinical trial included 40 patients of both sexes, aged 2.5 to 10 years. They were randomized into two equal groups [intervention to control (I/C) and control to intervention (C/I)]. The dietary intervention was 12-week honey consumption in a dose of 2.5g//kg body weight per dose twice weekly.

The objective of this study was to analyze the T cell metabolism and immune phenotype in AML patients during the course of the disease before and after allo-HCT.

Evaluation of the association between risk and severity of asparaginase associated toxicities and asparaginase enzyme activity levels in children with Acute Lymphoblastic Leukemia treated in the NOPHO-ALL 2008 protocol.

Over the past decades, advances in treatment have led to an increasing number of children who survive cancer, resulting in a growing population of childhood cancer survivors. After end of cancer treatment on common protocols survivors are enrolled in non-harmonized follow-up programs with frequent visits and blood samples. However, the evidence for the value of these follow-up programs with respect to the effect on detecting relapse and the effects on overall survival is scarce. The aim of the study is to give a comprehensive description of the detection mode of relapsed acute lymphoblastic leukaemia (ALL), including symptoms and blood test results. Further, we aim to evaluate if the mode of detection affects survival.

The purpose of this study is to describe the effectiveness of ibrutinib and to provide a description of ibrutinib therapy and the first non-ibrutinib subsequent therapy for chronic lymphocytic leukemia (CLL) and mantle-cell lymphoma (MCL).

The objective of this study is to establish the performance of an assay that detects mRNA transcript levels in patients diagnosed with CML. The study is conducted at locations within the United States. Testing is performed on peripheral blood specimens provided by eligible enrolled patients. Results from this study will not be used for patient management decisions.

The aim is to validate an in vitro diagnosis medical device to predict grade II to IV aGVHD after a cell graft

To detect SRSF2 gene mutation by polymerase chain reaction (PCR) in the two types of t-MDS/AML which recognized in the WHO classification. Association between SRSF2 gene mutation and the presence of other cytogenetic abnormalities in the two types of t-MDS/AML which recognized in the WHO classification, e.g. (Loss of chromosome 7 or del(7q), del(5q), isochromosome 17q, recurrent balanced chromosomal translocations involving chromosomal segments 11q23 (KMT2A, previously called MLL) or 21q22.1 (RUNX1), and PML-RARA). Relationship between SRSF2 gene mutation and cumulative dose, dose intensity, time of exposure and prognostic criteria (disease free survival, overall survival and disease course).

This study is a prospective, non-randomized feasibility study. Freshly isolated tumor cells from patients will be screened using state-of-the-art viability assay designed for ex vivo high-throughput drug sensitivity testing (DST). In addition, genetic information will be obtained from cancer and normal (germline) tissue and correlated with drug response. This study will provide the platform for informing treating physician about individualized treatment options. The main outcome of this study will be the proportions of the patients whose treatment was guided by the personalized medicine approach.
