Filter by:A novel method has been developed to expand natural (NK) cells and enhance their cytotoxicity against cancer cells while maintaining low killing capacity against non-transformed cells. In this method, donor NK cells are expanded by co-culture with the irradiated K562 cell line modified to express membrane bound IL-15 and 41BB ligand (K562-mb15-41BBL). Expression of these proteins in conjunction with unknown stimuli provided by K562 cells promotes selective growth of NK cells. Then, the expanded NK cell population is depleted of T cells to prevent graft versus host disease (GVHD). Expanded and activated NK cells showed powerful anti-leukemic activity against acute myeloid leukemia (AML) cells in vitro and in animal models of leukemia.Unpublished laboratory results also demonstrated that T-cell acute lymphoblastic leukaemia (T-ALL) is extremely sensitive to the cytotoxicity exerted by the expanded and activated NK cells. The present study represents the translation of the laboratory findings into clinical application. The study proposes to determine the feasibility, safety and efficacy of infusing expanded NK cells into patients who have AML or T-lineage ALL which is resistant to standard therapy as demonstrated by persistent minimal residual disease (MRD). Patients with myelodysplastic syndrome (MDS), who are at high risk to develop AML will also be eligible for the study. In this patient cohort, the study will also investigate the in vivo lifespan and phenotype of the expanded NK cells. The main hypothesis to be tested in this study is that infusion of expanded activated NK cells can produce measurable clinical responses in patients with AML or T-ALL.
The worldwide increase in the incidence of multidrug-resistant (MDR) pathogens is alarming. Antimicrobial treatment is a risk factor for the isolation of MDR pathogens and can therefore contribute to the observed trend. Differences in the degree of selection pressure caused by various antimicrobials have not been systematically investigated until today. The aim of the proposed project is the determination of the impact of antibiotic treatment on the copy number of resistance genes in the human intestinal microbiome using metagenome shotgun sequencing. The resistance gene count in the gastrointestinal tract will be determined in a clinical cohorts of patients treated with either ciprofloxacin or cotrimoxazol as monotherapy. The subsequent quantification and comparison of the selection pressure facilitates the application of antibiotics with a lower potential to select for resistance. To achieve this goal, a self-controlled, prospective observational epidemiological study will be performed at two centres of the German Centre for Infection Research (Tübingen, Cologne).
The purpose of this randomized, blinded, placebo-controlled study was to provide clinical safety and exploratory efficacy data on the use of Eltrombopag in adult subjects with Acute Myeloid Leukemia (AML) receiving standard induction chemotherapy with daunorubicin plus cytarabine. A minimum of 120 evaluable subjects newly diagnosed with AML was stratified by antecedent malignant hematologic disorder and age.
To determine whether a radiolabelled antibody that targets the bone marrow (the 'anti-CD66') can be administered safely to patients as part of the preparative treatment prior to haematopoietic stem cell transplantation ('a bone marrow transplant'). Can the radiolabelled antibody be shown to effectively target the bone marrow in these patients. If it can, could this result in better outcomes after transplantation.
The main objective of this project is not only a better understanding of the human leukemic disease but also to find new anti-leukemic or improve existing ones. This study has, the following aims: - To analyze the genetic and epigenetic regulation of the retinoic acid induced cascade which leads to the expression of TRAIL in blood cells of patients with acute leukemia. This study will be complemented by the analysis of global gene expression (DNA chips) and of the DNA methylation state, and by chromatin immunoprecipitation experiences. - To determine the efficiency of inhibitors of enzymes responsible for the modification of chromatin (existing and new developments within the European consortium EPITRON coordinated by Dr Gronemeyer) as inducers of differentiation and / or apoptosis of leukemic blasts. - To explore Ikaros genic and functional abnormalities (genomic deletions, mutations, abnormal transcripts and proteins) in acute leukemia. The aim is to determine if these abnormalities may play a prognosis role.
This is a phase II trial of reduced intensity conditioning with Bu/Flu/ATG in pediatric patients with hematologic malignancies at high risk for transplant related mortality with standard transplantation. Patients qualify based on organ system dysfunction, active but stable infection, history of previous transplant or late stage disease. We plan to enroll 45 patients through the Pediatric Blood and Marrow Transplant Consortium (PBMTC) and anticipate that the outcome of the trial will pave the way for phase II or III disease specific protocols addressing efficacy of the approach compared to standard transplant approaches in better risk patients.
This is a double blind, placebo controlled clinical trial, where patients with an advanced form of blood cancer are treated with haploidentical allogeneic peripheral blood progenitor cell (PBPC) transplant after which they are randomised to receive either placebo or a keratinocyte growth factor (Palifermin or Kepivance®). The function of Kepivance® is to stimulate the growth of epithelial cells. This drug has also been suggested to have an ability to help improve the reconstitution, or development, of the immune system after the transplantation. The hypothesis is that the patients T-cell dependent humoral immune response to recall antigen (PrevenarTM) will be higher in in palifermin treated patients than in the placebo control group
