Filter by:With current chemotherapy protocols, in 60-80% of patients with acute myeloid leukemia (AML) the leukemic blasts in the bone marrow can be reduced to < 5%. This is called "complete remission (CR)" and is the prerequisite for cure of the disease. During the last years, several genetic and biologic risk factors for the achievement of CR have been defined, and the remission rates vary considerably between patient groups with different risk profiles. On one hand, patients with certain chromosomal or molecular aberrations have very high CR rates of approximately 90%. Moreover, in some of these patients, molecularly targeted therapies for specific genetic aberrations are currently evaluated in clinical trials. However, these genetic aberrations account for only 50-60% of the overall patient population in AML. The remaining patients have a significantly inferior CR rate of only 50-60% with 30% resistant disease after two cycles of standard induction chemotherapy. In conclusion, there is need for improved induction regimens in a large number of adult patients with AML. An improved CR rate in this patient population will increase the number of patients eligible for intensive consolidation such as an allogeneic stem cell transplantation and might thereby be the basis for a better overall outcome. However, there is no clear evidence that this goal can be achieved with the currently available chemotherapy protocols. Clofarabine (2-chloro-2-fluoro-deoxy-9-D-arabinofuranosyladenine) is a nucleoside analogon which combines properties of fludarabine and cladribine. Due to the lack of neurological side effects, clofarabine could be explored in higher doses than other nucleoside analogues and has shown considerable antileukemic activity in patients with relapsed or refractory acute leukemias and elderly AML patients alone or in combination with cytarabine. In addition, the combination of clofarabine, cytarabine and idarubicin has produced promising results with acceptable toxicity in patients with relapsed or refractory AML. Based on these initial studies, there is need for a further optimization of the clofarabine dose in this combination. The aim of the AMLSG 17-10 study is therefore to evaluate the tolerability and safety of increasing doses of clofarabine in combination with idarubicin/cytarabine in patients with high risk AML defined by the genetic and molecular risk profile.
This is a multi-center, open-label, non-controlled, non-randomized dose-escalating Phase 1 clinical study designed to examine the safety of infusing escalating doses of CNDO-109-Activated Allogeneic Natural Killer Cells-(from a first or second degree relative), after a preparatory chemotherapy regimen, in adult patients with acute myeloid leukemia (AML) who are in their first complete remission at the time of enrollment, are not candidates for stem cell transplant, and are considered to be at high risk for recurrence.
The goal of this clinical research study is to learn if cladribine given in combination with low-dose cytarabine (LDAC) and decitabine can help control the disease in patients with AML or MDS. The safety of this drug combination will also be studied. Cladribine is designed to interfere with the cell's ability to process DNA (the genetic material of cells). It can also insert itself into the DNA of cancer cells to stop them from growing and repairing themselves. Cytarabine is designed to insert itself into DNA of cancer cells to stop them from growing and repairing themselves. Decitabine is designed to damage the DNA of cells, which may cause cancer cells to die. This is an investigational study. Cladribine is FDA approved and commercially available for use in patients with hairy cell leukemia. Its use in patients with AML is investigational. Cytarabine is FDA approved and commercially available for use in patients with AML. Decitabine is FDA approved and commercially available for use in patients with MDS. Its use for patients with AML is investigational. Up to 160 patients will take part in this study. All will be enrolled at MD Anderson.
The purpose of this study is to evaluate the safety and the efficacy of combined treatment strategy of WT1ASCI, infusion of ex vivo regulatory T cells depleted T lymphocytes and in vivo regulatory T cells depletion as post-consolidation therapy in patients with WT1-positive Acute Myeloid Leukemia. The study will also evaluate the clinical activity and immune response of this approach in bad risk patients in CR1 and all patients in CR2 or CR3, non eligible for an allogeneic Hematopoietic Stem Cell Transplantation
To compare the antitumor efficacy and toxicity of Idarubicin and cytarabine in combination with or not with infusions of granulocyte colony-stimulating factor-mobilized HLA-mismatched donor peripheral blood stem cells in patients with newly diagnosed high-risk acute myeloid leukemia (AML).
ClAraC (consisting of one dose of clofarabine and ara-C for five days) or FLAMSA (consisting of one dose of fudarabine, amsacrine and ara-C for four days) will be administered followed by reduced-intensity conditioning regimen (RIC) in the setting of allogeneic stem cell transplantation (SCT). The aim of the study is to explore the antileukemic, immunosuppressive effects and toxicity and safety of clofarabine in combination with ara-C in the setting of RIC allogeneic transplantation compared with the FLAMSA-protocol for patients with high-risk acute myeloid leukemia (AML) or advanced myelodysplastic syndrome (MDS).
This protocol is part of the German AML Intergroup Trial, where the OSHO study arm is compared to the common German standard arm after randomization in a 9:1 ratio. The hypothesis involves primarily dosing and application of AraC for induction. It is expected that CR rates and as a consequence also LFS are higher in protocols using higher AraC compared to lower doses and that LFS might be superior in the study specific arm compared to the golden standard published several years ago. In the standard arm, AraC 100mg/m2/day is given as continuous infusion over 7 days. Daunorubicin is given as 60 mg/m2/day over a two hours infusion on days 3, 4 und 5. On day 22 a second induction course is applied. After reaching CR, three cycles of AraC 3 g/m2 over three hours bid are infused on day 1, 3 und 5. In contrast the OSHO arm consists of induction therapy with IDA 12 mg/m*2 over 20-30-min-iv on day 1 - 3 and AraC 2 x 1 g/m*2 bid over 3-h-iv on days 1+3+5+7. A previous phase II study of the OSHO has shown high CR in patients with relapsed AML using MitoFlag. In this study we asked the question if MitoFlag is superior to IdaAraC in newly diagnosed AML patients without CR after the first induction chemotherapy. Therefore patients are randomized to receive either MitoFlag or IdaAraC and the difference in CR rates evaluated. It is still unclear if two consolidation therapies are needed before allogeneic or autologous stem cell transplantation. This question is being addressed in the second part of the OSHO study, where patients are randomized to receive either one or two consolidation therapies. In this study all patients with AML and an age of 18-60 years except M3 are entered
Patients with relapse of acute leukemia often only receive supportive therapy. Our hypothesis is that a combination therapy can stabilize the disease for patients with early relapse after allogeneic stem cell transplantation. The investigators will combine 5-azacitidine 100 mg daily subcutaneously (days 1-3), valproic acid (continuous therapy from day 1), All-trans retinoic acid (days 1-14) and hydroxurea (continuous treatment from day 15 of first cycle. Azacitidine and ATRA can be repeated with 5 weeks intervals, donor leukocyte infusions on day 10 is allowed from the second cycle.
This study is an access and distribution protocol for unlicensed cryopreserved cord blood units (CBUs) in pediatric and adult patients with hematologic malignancies and other indications.
SEIFEM 2010 study is a prospective, multicenter registry designed to identify and analyze risk factors for developing an invasive fungal infection in patients with newly diagnosed Acute Myeloid Leukemia, with particular interest on pre-hospital risk factors (i.e. those related to normal activities of daily life, such as occupation, location and type of residence, consume of tobacco, alcohol and others).
