Filter by:The purpose of this study is to confirm whether the bispecific T cell engager blinatumomab (MT103) is effective, safe and tolerable in the treatment of ALL patients with minimal residual disease.
This study will test the ability of clofarabine + cytarabine to eliminate minimal residual disease (MRD) in acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL) patients whose bone marrows exhibit complete remission by morphology. The toxicity profile of this regimen will be evaluated in addition to toxicity experienced by patients who proceed to stem cell transplant. Overall length of remission will also be collected.
To determine if MRD (minimal residual disease) can be found in the blood (only) as opposed to bone marrow in children with ALL (acute lymphoblastic leukemia).
RATIONALE: Drugs used in chemotherapy, such as clofarabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving clofarabine together with cytarabine may kill more cancer cells. PURPOSE: This pilot phase II trial is studying how well giving clofarabine together with cytarabine works in treating patients with acute myeloid leukemia with minimal residual disease
Although allogeneic stem cell transplantation is curative in CML, evidence of the BCR-ABL oncogene at low levels is still found in long-term follow-up of survivors. Such low levels of BCR-ABL post-transplant which do not fulfill criteria for molecular relapse are monitored regularly and considered to be suppressed by the GVL effect. Treatment with donor lymphocyte infusions is only instituted when quantifiable BCR-ABL transcript levels rise steadily, indicative of a true molecular relapse . Similarly, BCR-ABL is still detectable in the majority of CML patients treated with imatinib who achieve complete cytogenetic response, although the amount of BCR-ABL transcripts seem to decline with longer follow-up. With 5 years follow-up of CML patients at CP who received imatinib, the estimated cumulative best rates of complete hematologic response and complete cytogenetic response were 98 percent and 87 percent, respectively10. For the minority of CP-CML patients who do not respond satisfactorily to imatinib, second-generation tyrosine kinase inhibitors are now the recommended next line of treatment. A major question facing clinicians is whether imatinib and the other more pharmacologically potent second-generation tyrosine kinase inhibitors;can suppress the CML clone at the leukemic stem cell level as effectively as allogeneic stem cell transplantation. This protocol is designed to scientifically compare the treatment responses of patients who are treated with allogeneic stem cell transplantation with patients who receive imatinib or second generation tyrosine kinase inhibitors. The primary endpoint of this trial will be the proportion of patients who have detected minimal residual disease (DMRD) in primitive CD34 plus progenitor subpopulations no earlier than 60 days from the onset of their respective treatments.
The aim of this clinical study in adult ALL is to compare by risk category (1) the feasibility of two different CNS prophylaxis regimens and (2) the overall disease-free survival in relation to the achievement of an early MRD negative status and following consolidation with lineage-targeted methotrexate infusions and other disease-specific therapeutic elements, with or without the application of allogeneic or autologous SCT depending on risk class and MRD study results. In this multicentric prospective pilot randomized phase II trial on CNS prophylaxis, all patients receive induction/consolidation therapy incorporating lineage-targeted high-dose methotrexate plus other drugs (with additional imatinib in Ph/BCR-ABL+ ALL), for the achievement of an early negative MRD status. The MRD study supports a risk/MRD-oriented final consolidation phase.
The purpose of this study is to determine whether the bispecific T-cell engager (BiTE®) Blinatumomab (MT103) is effective in the treatment of ALL patients with minimal residual disease.
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. PURPOSE: This phase II trial is studying the side effects and how well alemtuzumab works in treating patients with B-cell chronic lymphocytic leukemia in partial remission or complete remission.
The study aims to optimize the concept of risk-oriented postremission consolidation therapy, by offering (i) standard consolidation-maintenance to patients at lowest risk of relapse as defined by MRD(Minimal Residual Disease) negative status, and (ii) allogeneic stem cell transplantation (related/unrelated donor available) or multicycle high-dose therapy with autologous blood stem cell transplant (no donor) to patients at highest risk of relapse as defined by MRD+ status. The prognostic role of MRD evaluation in unselected patients will be evaluated.
The goal of this clinical research study is to learn if giving 1 of 2 CML (Chronic Myeloid Leukemia) vaccines (CML-VAX B2 or CML-VAX B3) together with imatinib mesylate can decrease or eliminate all evidence of disease in patients who have CML that is in remission after treatment with imatinib mesylate, but who still have small amounts of detectable disease.
