Filter by:The survival of adult patients with standard-risk acute lymphoblastic leukemia(ALL) need to improve. We want to compare the efficacy of haplo-identical hematopoietic stem cell transplantation (HSCT) with chemotherapy for adult(age:18-39 years old) ALL patients in first phase of complete remission (CR1)
A retrospective analysis of historical data looking at relapse free survival and overall survival rates in adult philadelphia negative B-pre-cursor acute lymphoblastic leukemia patients.
The reconstitution of a functioning immune system after allogeneic stem cell transplantation takes months to years. Particularly memory B-lymphocytes reconstitute poorly with the current conditioning regimes. During the period of intense immune suppression the patients are extremely susceptible to bacterial, fungal and, most importantly, viral infections.The adoptive transfer of B-lymphocytes from the stem-cell donor might significantly enhance humoral immunity for the patient. Aim of the study is to evaluate a new cellular therapy with B-lymphocytes regarding safety. A booster vaccination after B-lymphocyte transfer will evaluate the functionality of the transferred B-lymphocytes in the patient.
A retrospective analysis of historical data looking at hematological remission and survival in adult relapsed / refractory B-precursor acute lymphoblastic leukemia patients.
This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.
This randomized clinical trial studies standard GVHD prophylaxis with tacrolimus and methotrexate compared to tacrolimus, mycophenolate mofetil and a reduced-dose methotrexate in patients with hematologic malignancies undergoing allogeneic hematopoietic cell transplant. Both mycophenolate mofetil and reduced-dose methotrexate, in combination with a calcineurin inhibitor, have been shown to be safe and effective in GVHD prevention with less toxicity than standard dose methotrexate. It is not yet known, however, whether this combination of mycophenolate mofetil and reduced-dose methotrexate with tacrolimus is more effective than tacrolimus and standard dose methotrexate in preventing GVHD.
The purpose of this study is to test the safety of a study drug called CPX-351. This drug has been tested in adults but not yet in children and adolescents. This study tests different doses of the drug to see which dose is safer in children and adolescents. Patients who have blood cancer are being asked to take part in this study . Blood cancers may include leukemia and lymphoma. Patients able to be in this study have already been treated with standard chemotherapy for their disease and the disease is still growing or has come back. CPX-351 is a drug that is not yet approved by the United States Food and Drug Administration (FDA) and is only used in research studies like this one. CPX-351 is made up of two chemotherapy drugs that patients may have already received called cytarabine and daunorubicin that are now packaged together. Another purpose of this study is to collect blood samples for special research studies. Researchers want to study how much of the CPX-351 is in the body over time. These studies are call pharmacokinetic studies or PK studies for short. PK studies require the collection of several blood samples before and after participants are given the study drug.
Asparaginase (Asp) is used during the induction phase of ALL treatment for children and young adults. Its efficacy is counterbalanced by its toxicity, mainly in patients 40 years or older. The efficacy rate in older adult population is lower than for children or young adults. A recent review on outcomes in older adults with ALL pointed out that there were significantly more drug reductions, omissions or delays in the older group as compared to younger adults and that asparaginase was the drug most commonly omitted. The investigational product ERYASPASE is a dispersion for infusion of homologous red blood cells (RBC) encapsulating E. coli L-asparaginase. A previous European phase I/II clinical study in children and adults (<55 yo) at first relapse of ALL was conducted to determine the optimal dose of homologous RBC encapsulating native E. coli Asp (GRASPA®) in 24 patients with relapsed ALL. The activity and safety profiles of 3 doses of GRASPA® (50, 100 and 150 IU/kg) in combination with standard chemotherapy were compared to free native Asp. The global safety profile is also improved, reducing hypersensitivity, liver toxicity and coagulation disorders. Study showed that a single dose of GRASPA® 150 IU/kg induced a depletion in plasmatic asparagine for 18.6 days, i.e. similar to that obtained with 8 injections of 10,000 IU/m² of free native Asp. A reduction in the incidence and severity of the allergic reactions and coagulation disorders were observed with GRASPA® (Domenech 2011). A French phase II study designed to determine the maximum tolerated dose of GRASPA® in combination with a polychemotherapy regimen in ALL patients older than 55 yo at first diagnosis has been performed, and showed that both 100 and 150 IU/kg doses fulfilled the predefined criteria for efficacy and tolerability but the better profile of 100 IU/kg dose was considered the optimal dose in this setting. A phase II/III trial in adult and children patients with relapsed ALL is currently ongoing. Based on these results, the combination of ERYASPASE with the CALGB chemotherapy regimen appears to be an attractive combination for the treatment of adults patients with ALL/LBL.
Acute lymphoblastic leukemia (ALL) accounts for 30 % of all childhood malignancies. The patients undergo four phases of treatment, finishing with a late maintenance phase in which 6-mercaptopurine and Methotrexate are essential components. Insufficient treatment intensity in this phase is associated with increased risk of relapse. Excessive variation in the bioavailability of 6-mercaptopurine has been observed which can cause both risks of undertreatment/relapse as well as overtreatment with severe side effects. In the attempt to achieve individualized 6-mercaptopurine dosing different approaches have been pursued. Nonetheless variation in bioavailability remains a problem. Earlier, oral tablets of 50 mg (Purinethol) were the only administration form of 6-mercaptopurine and it was primarily designed for adult patients. Challenges with accurate dosing and getting the children to swallow the tablets have been a widespread problem, forcing the caregivers to divide or crush the tablets as well as having to administer different dosages over 2-3 days. Due to these problems, an oral liquid formulation of 6-mercaptopurine (Xaluprine) has been developed. However this oral liquid has only been tested on healthy adult volunteers, and not on the target group, childhood patients. This project will assess the bioavailability and plasma kinetics of oral liquid and tablet formulation of 6-mercaptopurine in children with acute lymphoblastic leukemia. The investigators hypothesize to observe comparable plasma kinetics, in children with acute lymphoblastic leukemia when treated with 6-mercaptopurine in the form of a tablet and oral liquid formulation, as previously observed in healthy adults.
The purpose of this study is to explore the impact of thiopurine methyltransferase (TPMT) activity on the risk of HDM-related bone marrow- and hepatotoxicity and treatment interruptions during maintenance therapy for children with ALL. Hypothesis of the study: Patients with TPMT activity compatible with TPMT low activity polymorphisms have an increased risk of toxicity following high-dose methotrexate (HDM) compared to children with normal TPMT activity.
