Efficacy and Toxicity of Blinatumomab in the French ATU for Adult BCP-ALL R/R, or With MRD+ (FRENCH-CYTO)...

Acute Lymphoblastic Leukemiain Relapse1 more

The outcome of young adults (18-60 years) with ALL has been dramatically improved by the use of pediatric-inspired trials. About 60% of these young adult patients will be cured at 5 years. In this context, early evaluation of minimal residual disease (MRD) at complete remission has been shown to be one of the most powerful prognostic factor, but also predictive of the benefit of allogeneic stem cell transplantation (ASCT). Despite this global improvement, about 30% of patients experience a relapse and will be exposed to be refractory to salvage therapy or to early disease escape. In adult ALL, the most important prognostic factors at relapse are : the time from first CR to relapse, the achievement of a second complete remission (CR), and the feasibility of ASCT. Blinatumomab is a bispecific T-cell engager that recruits T-cell on CD19 positive blast cells and induces anti-leukemic cytotoxicity. In a phase 3 trial in relapse/refractory Philadelphia-negative (Ph-) ALL, 43% of patients achieved a CR or CR with partial hematological recovery (CRh), with the majority of responses occurring within the first cycle. In patients with positive MRD (MRD+) BCP-ALL, blinatumomab resulted in complete MRD response in 78% of patients after one cycle. Between 2012 and 2016, blinatumomab was available in France for R/R and MRD+ ALL adult patients through the French Compassionate Use Program. About 92 adult ALL were treated at different stages of the disease in 27 centers.

RFC and MTHFR SNPs & hENT1- dCK Expression as Prognostic Factors in ALL & hENT1- dCK Expression...

Acute Lymphoblastic Leukemia.Acute Myeloblastic Leukemia

Results of actual treatment in ALL are not optimal. New prognostic factors, which may determine clinical & molecular response are required. Hyper-CVAD is an internationally accepted schema for such patients. The objective of this pilot study is to evaluate polymorphisms regarding RFC (reduced folate carrier) and MTHFR enzyme, which may affect the function of these proteins, and therefore the intracellular bioavailability of methotrexate. Also, the expression levels of hENT1 and dCK will be evaluated, since such genes codify for citarabine intracellular transport and activation, respectively. Clinical characteristics will be tabulated and analyzed for responders & non-responders patients. Uni- & multivariate analysis will be done to evaluate factors influencing on response and survival.

Heavy Light Chain in Chronic Lymphocytic Leukemia

CLL

Recently, a novel assay for detecting heavy/light chain (HLC) ratios has been reported which enables improvement in paraprotein detection and monitoring in multiple myeloma and other plasma-cell dyscrasias. The prognostic and biological role of the HLC assay has as yet not been studied in CLL. Aims of the proposed study: To quantify and analyze the prognostic significance of HLC ratios in the serum of CLL patients. (In addition to FLC) To study the different patterns of Immunoglobulin's subclass antibodies in the serum of patients with CLL and compare them to those of to healthy volunteers. To perform a sub-analysis in patients with CLL who have autoimmune phenomenon (AIHA and ITP)

Tyrosine Kinase Inhibitors and Low Intensity Chemotherapy in Ph+ ALL

Lymphoblastic LeukemiaAcute

The use of imatinib in combination with chemotherapy is now considered as the gold standard for the treatment of Ph+ ALL. The complete remission (CR) rate is 90% versus 20% to 40% with chemotherapy alone. The combination of imatinib, vincristine and dexamethasone is a well tolerated regimen in aged patients and is also associated with a high CR rate of 80% to 90% in patient aged 55 years and over. 2. Dasatinib is indicated as first line therapy in Ph+ ALL. Results from the EWALLPH-01 are supporting the use of dasatinib in combination with low-intensity chemotherapy. A new EWALL-PH-02 study combining nilotinib in combination with low-intensity chemotherapy is currently initiated within the EWALL centers. 3. The EWALL-PH-01 trial is now closed after the recruitment of 71 patients. The activation of the EWALL-PH-02 trial is expected for Q1 2012. Based on the recruitment of the EWALL-PH-01 study it could be anticipated that 50 to 100 patients aged more than 55 years will be diagnosed during this 6 months period of time. In addition, all the EWALL centers are not participating to the EWALL-PH-02 study and thus these centers could be offered to treat patient following the EWALL backbone in addition to imatinib. 4. A minimum data set will be defined in order to collect the data of the patients treated following the EWALL-PH imatinib study. The main recommendation is to follow as close as possible the procedures of the EWALL-PH-01 trial (mutation analysis, MRD follow-up) in order to have a comparable data set. This imatinib treated cohort of patients would be of particular importance in order to better define the potential benefit of using one TKI compared to one other. From the end of the EWALL-PH-01 study recruitment to the initiation of the EWALL-PH-02 study, patients were treated following the common backbone schedule in combination with imatinib or others TKI. Patients not included in clinical trials for other reasons were also offered a treatment with the combination of TKIs and backbone low-intensity chemotherapy. The goal of this observatory retrospective and prospective is to describe the efficacy and the tolerance of the combination of tyrosine kinase inhibitors in combination with low intensity chemotherapy (EWALL backbone) in patients with Ph+ ALL aged 55 years and over.

Functional Pharmacogenomics of Childhood Acute Lymphoblastic Leukemia in Taiwan

LeukemiaLymphocytic1 more

Emerging results suggest that a cure rate of nearly 90 percent will be attained in the near future. The advance was attributed to stringent application of prognostic factors for risk factor-directed therapy. Early response to treatment has greater prognostic strength than does any other biologic or clinical feature tested to dates. The measurement of minimal residual disease(MRD) affords a level of sensitivity and specificity that cannot be attained through traditional microscopic morphologic assessments. In Taiwan, detection for the most recurrent fusion genes and the MRD were not commonly available, the TPOG(Taiwan Pediatric Oncology Group) used clinical features, immunophenotypes, and cytogenetics to do risk group classifications and protocol assignment. A successful rate of 60-70% has been reached. In order to improve the cure rate of ALL in Taiwan, this project aims at establishing the methods for better risk classifications and establishing MRD detection for risk-directed therapy for childhood ALL in Taiwan.Intrinsic and acquired resistances to multiple anticancer agents represent major obstacles and accounts for 10-20% of treatment failure in the developed countries nowadays. Recent progress using DNA microarray identified differential expression level of the genes known to implicate in cell cycle control, DNA repair and apoptosis in different subsets of ALL patients, which were found to be related to drug response. Genetic polymorphisms in the genes of drug-metabolizing enzymes, drug transporters or drug targets, can influence the efficacy or toxicity of antileukemic agents. Specific genotype might be important in determining the pharmacokinetic effects of one population or disease subtype from that in others. Recently, the expression profiles of relatively few microRNAs (miRNAs) (~200 genes), was noted to accurately classify human cancers. These informations hinted that expression of the genes in the leukemic cells might serve as additional risk factors for treatment stratification. Specific aims and goals: to establish better risk factors classification and use MRD to monitor early response to treatment. to establish the expression profiles of 12 genes associated with drug resistance to unravel the pharmacogenetic background of pediatric ALL in Taiwan, so that will help refine the therapy dose, achieve a better drug effect and avoid acute or chronic toxicity. microRNA expression profiles in childhood ALL in Taiwan
