Filter by:The study will assess the role of high-dose imatinib mesylate, in patients who have taken imatinib mesylate for at least 1 year at the standard dose, in achieving a major molecular response (a measure of the level of chronic myelogenous leukemia) versus the standard dose.
The objectives of Part 1 of the study were: - To determine the rate of hematologic response (HR) lasting ≥4 weeks in participants with Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) in the accelerated phase (AP). - To evaluate duration of HR, overall survival, cytogenetic response (CyR), time to blast crisis in CML participants in the AP, improvement of symptomatic parameters, tolerability and safety of STI571 treatment. The objective of the extension (Part 2) was: -To enable participants to have access to study drug and continue study treatment and to decrease data collection to include only overall survival and serious adverse events.
During the Core Phase of the study, participants received STI571 at a dose of 400 milligrams (mg) daily for up to 12 months. Participants completing 12 months of therapy were eligible to continue treatment in the Extension Phase of the study provided that, in the opinion of the investigator, they had benefited from treatment with STI571 and there were no safety concerns.
The purpose of this study is to test the hypothesis that a pre-infusion preparative regimen of cyclophosphamide and fludarabine will improve the effectiveness of DLI in patients with blood cancers.
In this study our hypothesis is that infusion of donor lymphocyte immune cells from the subject's bone marrow donor will activate the subject's immune system to attack their cancer.
Donors with CM will be solicited from a waiting list of patients awaiting BMT from the waiting list of MUD searches. Maximally matched donor will be searched for each eligible CML patient with a goal in mind to find other patients with CML that share both class I and class II determinants. Sharing of one class I II will be considered eligible for participation in the study. Peripheral blood and PBMC from the donors will be isolated, washed and irradiated. The cells will be injected into the consenting patients intracutaneously at 2 weeks intervals for a total of 6 injections.
There are naturally occuring variations in the genetic makeup of all of us. Some of these variations may contribute to a change in susceptibility toward different diseases or change the prognosis. We are studying these genetic variations in patients with leukemia. The genes we are studying are those which influence detoxification of drugs and toxins.
Bone marrow consists of a complex hematopoietic cellular component.When the blood progenitor cells differentiate to mature cells, they will exit unassisted to peripheral blood. On the other hand, the immature cells trapped by marrow-blood barrier. However, malignant transformation of the hematopoietic progenitor cells in AML and CML results in a blockade of their ability to terminally differentiate, causing a rapid accumulation of immature cells.Chemokines have been shown to direct the movement of cells between intravascular and extravascular compartments.The CXC chemokine CXCL12, the ligand of CXCR4, activates distinct signaling pathways that may mediate cell migration.In the preliminary research, we analyze the CXCR4 expression and the chemotactic response of CXCL12 and peripheral plasma in six leukemia cell lines (HL-60, HL-CZ, K562, U937, Raji and Jurkat) and found that three categories among them could be suggested: one is CXCR4 (-) and CXCL12 response (-), such as HL-CZ and K562 cells; the other is CXCR4 (+) and CXCL12 response (-), such as HL-60 and Raji cells; the rest is CXCR4 (+) and CXCL12 response (+), such as Jurkat and U937 cells. These results make us wonder that the leukemic cells could egress to PB from BM is due to destruction of homing process or the activation of mobilization process through CXCR4-CXCL12 axis dysfunction. Therefore,we will focus on evaluating the mechanism of CXCR4-CXCL12 axis dysfunction in the various leukemic cell lines and primary leukemic cells.
In this trial, HLA-A2+ patients with active AML are vaccinated with a peptide from the leukemia-associated antigen WT1 together with immunological adjuvants keyhole limpet hemocyanin (KLH) as T-helper protein and granulocyte macrophage colony stimulating factor (GM-CSF) 4 times bi-weekly, then monthly.
The purpose of the study is to determine whether voriconazole is as effective as antifungal prophylaxis in patients undergoing chemotherapy for acute myelogenous leukemia (AML). Hypothesis: Voriconazole is superior to placebo in the prophylaxis of lung infiltrates until day 21 after the start of induction chemotherapy.
