Filter by:While several studies have been reported with increasing doses of daunorubicin in the first line treatment of Acute Myeloid Leukemia (AML), there is no similar experience with idarubicin as initial treatment of AML. As idarubicin is the most common treatment used for AML, it is needed to find the optimal dose for the combination of idarubicin, cytarabine and G_CSF, to explore if this combination improves the outcomes of current treatments for AML. The aim of this dose-finding study is to find the optimal dose for the combination of idarubicin, cytarabine and G-CSF that could improve the response rate, reduce relapse and improve survival of patients with primary acute myeloid leukemia. This could be a significant advance in a field where treatment outcomes have stabilized in the last 15 years. This study will be the basis for further prospective, randomized, multicenter trial comparing idarubicin maximum tolerated dose, compared to standard treatment with idarubicin and cytarabine, including raising both arms in G-CSF. The dose of 12 mg/m2 will be administered as control arm in this future randomized study, which will investigate the benefit of enhanced dose identified as optimal in this phase II pilot study.
The GIMEMA CML Working Party promotes a multicentre, observational, prospective study of CML patients treated frontline with NIL. Patients will be followed for 5 years. This study will help the definition of guidelines for the treatment of CML patients in early CP.
A clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.
Acute myeloid leukemia (AML) is a neoplasm of immature hematopoietic cells (blasts) with altered ripening capacity. Due to excessive proliferation, the blasts displace normal hematopoietic cells and bone marrow failure appears. Leukemic cells also infiltrate extramedullary tissues. Following the standard chemotherapy treatment, the CR rate achieved is around 65-75% for all patients and 15% lower when considering only patients over 65 years. Modifications to the standard regimen consist of replacing the DNR for a cytotoxic one, modifying the dose of ara-C or adding a third drug. Gemtuzumab ozogamicin (Mylotarg ®) is an immunoconjugate between anti-CD33 antibody and a cytotoxic antitumor antibiotic, calicheamicin. Mylotarg ® antibody specifically binds to CD33, a sialic acid-dependent adhesion protein expressed in over 90% of LMA10. Mylotarg ® selectively transports the cytotoxic agent calicheamicin into leukemic cells and hematopoietic progenitors differentiated from the myelomonocytic line, while respecting the pluripotent hematopoietic stem cells. Calicheamicin is released only after the fixation of the antibody anti-CD33 and its internalization by the cell, after which binds to and damages the DNA. Mylotarg ® is approved in the U.S. for the treatment of CD33 positive AML in first relapse, for patients older than 60 years non-candidates for other intensive treatment modalities. Since the efficacy of Mylotarg ® is equivalent and its toxicity profile less than the conventional therapy, it is logical to conduct a phase II trial exploring the role of Mylotarg ® in the early stages of treatment of AML. Previous experience with gemtuzumab ozogamicin in relapsed patients led to its use combined with induction chemotherapy. The aim was to improve the CR rate reached with the latter and reduce relapse after achieving greater leukemic cytoreduction. Recent data from the HOVON group support that the administration of G-CSF before and during induction chemotherapy decreases the incidence of relapse in patients with AML, particularly those considered to have intermediate risk. Everything mentioned above justifies to investigate the combination of GO combined with chemotherapy with IDR and ara-C in standard 3x7 scheme and analyze the effect of sensitization with G-CSF in patients with AML de novo. If the treatment proposed here is effective and presents an acceptable toxicity it should be investigated.
This is a Phase II, open-label, two strata, multicenter, prospective study of plerixafor-mobilized HLA-identical sibling allografts in recipients with hematological malignancies. This study will establish the safety and efficacy of subcutaneous plerixafor for this purpose.
To confirm the efficacy of CPX-351 compared to 7+3 as first line therapy in elderly patients (60-75 yrs) with high risk (secondary) Acute Myeloid Leukemia. The primary efficacy endpoint will be overall survival.
Patients with acute myeloid leukemia who experience a relapse after at least one prior regimen may be enrolled in this trial. In addition, acute myeloid leukemia patients who are in complete remission with high risk to relapse may be eligible for this trial. The trial will examine whether monotherapy with BI 836858 is safe and tolerable at escalating dose levels.
This randomized phase II trial studies how well donor umbilical cord blood transplant with or without ex-vivo expanded cord blood progenitor cells works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy stem cells and ex-vivo expanded cord blood progenitor cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving donor umbilical cord blood transplant plus ex-vivo expanded cord blood progenitor cells is more effective than giving a donor umbilical cord blood transplant alone.
Demethylating agent decitabine enhances the immunogenicity of leukemia cells by inducing the expression of cancer testis antigens (CTAs),MHC class I and II molecules,costimulatory molecules and adhesion molecules. The leukemias cells treated by decitabine will become more sensitive to the following adoptive T cell therapy.
The current standard therapy in previously untreated adults with chronic phase (CP) of CML is imatinib and the result of long-term follow-up of IRIS study proves that imatinib for CML CP is reasonable therapy.(1, 2) However, some patients were initially diagnosed as advanced CML, accelerated phase (AP) or blastic phase (BP). Various chemotherapies were tried and were found that there were no highly effective chemotherapies for CML BP.(3-11) Imatinib in patients with these advanced CML is also disappointing because of low response rates as well as short response duration, and sudden transformation to BC is found even in initial CML CP patients. (12-17). Recent studies showed that nilotinib or dasatinib is better than imatinib in terms of rapid response and higher molecular response in newly diagnosed CML patients.(18-21) More potent bcr-abl suppression of nilotinib is supposed to be more active than imatinib even in patients with advanced CML. However, nilotinib in patients with imatinib-resistant or -intolerant CML BP showed low hematologic response and major cytogenetic response.(22, 23)
