Filter by:The purpose of this study is to obtain high quality specimens for molecular studies for the identification and characterization of genetic mutations involved in the pathogenesis of familial myeloid malignancies. Specimens obtained will be de-identified, linked to basic clinical data, and sent to Washington University (Division of Oncology, St. Louis, MO) for molecular analyses. Some specimens sent to Washington University may also be used for quality control analyses.
Pilot study of the efficacy and tolerance of the adjunction of a Fish oil emulsion to daunorubicin and cytarabine chemotherapy for the treatment of Acute MYeloblastic Leukemia of Younger patients (under 61 years) with high-risk cytogenetics.
This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000mg iv infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.
The purpose of this study is to learn if 5'-Azacitidine will help to lower the risk of the disease coming back after a stem cell transplant in patients with MDS and AML. This study will also be looking at the side effects of this medicine. 5'-Azacitidine is an FDA approved drug for treatment of MDS and AML, as well as patients whose disease came back after transplant, where it helped going into remission. It is unclear if 5'-Azacitidine can prevent the disease from coming back after transplant. This study will help show if getting 5'-Azacitidine soon after transplant can lower the risk of your disease coming back.
This was a Phase 2, open-label, multicenter study evaluating the preliminary efficacy and safety of venetoclax (ABT-199) administered orally in participants with acute myelogenous leukemia (AML).
This study will identify the highest dose, and assess the safety, of cerdulatinib (PRT062070) that may be given in participants with relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma or non-hodgkin lymphoma.
Acute leukemias are a heterogeneous group of hematologic malignancies. They result from clonal expansion of immature cells whose number is greater than 20% in bone marrow. Childhood acute leukemias are the most common pediatric malignancies. In Europe and the United states, they represent about 35% of childhood cancers. 80% of them are acute lymphoblastic leukemia (ALL) and 15-20% of acute myeloid leukemia (AML). Current treatments allow a cure in about 80% of ALL, while this level is only 50% in AML.Acute leukemia diagnosis is based on the multidisciplinary exploration of leukemia cells by different techniques: - Cellular: cytology, immunophenotyping and cytochemistry - Cytogenetic: conventional (karyotype) and molecular (FISH) cytogenetic - Molecular: RT-PCR and RQ-PCR Cytogenetic studies are performed at time of acute leukemia diagnosis. Indeed, the WHO 2008 classification of acute leukemia is based largely on the presence of recurrent cytogenetic and molecular abnormalities. The most frequent chromosomal aberrations have been associated with specific clinical and biological characteristics and are now used as diagnosis and prognostic markers. These chromosomal abnormalities affect genes involving in the leukemogenesis process. These rearrangements are of several types: - Fusion genes causing : - Repression of transcriptional activity of genes involved in differentiation of hematopoietic cells (AML1-ETO, PML-RARA…) - Deregulation of signal transduction pathway (eg BCR-ABL chimeric protein with constitutive tyrosine kinase activity) - Changing in the state of chromatin condensation resulting changes of transcription (MLL gene rearrangements in 11q23, MOZ en 8p11…) - Deregulation of genes expression: chromosomal rearrangements can sometimes induce deregulation of adjacent genes to the breakpoint. For example, inv(3)(q21q26) or t(3;3)(q21;q26) induce over expression of transcriptional factor EVI-1. - Loss of function due to deletion of variable size in genomic regions containing genes with a role in the differentiation, apoptosis, or cell proliferation (eg IKZF1, PAX5…) In addition to the karyotype, which allows to have a global view of the genome; FISH, a targeted technique, is used to highlight invisible abnormalities on karyotype (cryptic abnormalities) or the time of karyotype failure. However, conventional and molecular cytogenetic techniques do not highlight any abnormalities (eg different partners involved in the formation of fusion genes in particular for MLL gene rearrangement, mutations) hence our interest in next generation sequencing.Indeed, the high throughput targeted sequencing messenger RNAs (RNA-seq) has the avantage of allow identification of different types of mutations in a single test, with exception of epigenetic mutations. The importance of RNAs sequencing rather than DNA genomic is the one hand, a very significant decrease in the volume of sequences to analyze because transcribed mRNA genes represent about 5% of the genome size and secondly, a better identification of chimeric genes. The RNA-seq has used as a research tool in hematologic malignancies. The purpose of this project is to use innovative technology to develop a new diagnostic and prognostic new tool in hematological malignancies. 50 acute leukemias will be tested and results will be analyzed according to three criteria: - Quantity, quality and relevance of information provided for the diagnosis, monitoring and therapeutic management compared to a conventional strategy - Period required to obtain results and methods to decrease the analysis time so that results can be integrated into therapeutic decisions. - Economic evaluation, which will calculate the cost of this diagnosis option and assess the cost/benefit ratio In future, other innovative approaches will be implemented (study of imbalances genomic abnormalities by array-CGH, transcriptome analysis with micro-array, and study of methylome) to identify the "molecular signature" of each leukemia and set of informative abnormalities for diagnosis, prognosis and treatment of disease and monitoring of residual disease.
This open-label, Phase I study will evaluate the safety, tolerability, and pharmacokinetics of increasing doses of GDC-0853 in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia. In a dose-expansion part, GDC-0853 will be assessed in subsets of patients.
The cure rate for childhood acute lymphoblastic leukemia (ALL) has increased significantly in recent decades and expected cure rates now exceed 85%. In recent years, Tyrosine Kinase Inhibitor(TKI) has improved outcome of Philadelphia chromosome positive (Ph+)ALL . But in some high risk groups, The prognosis of patients is still very bad and the relapse rate is high. Clearly, new therapies are urgently needed to prevent and /or treat relapsed ALL.
In this prospective randomized study for patients with newly diagnosed acute promyelocytic leukemia, patients will be randomized (1:1) into two groups which receive retinoic acid and arsenic trioxide based treatment versus retinoic acid and chemotherapy based regimen.
