The purpose of this study is to determine the safest dose of the BCR-ABL inhibitor XL228, how often it should be taken, and how well people with leukemia tolerate XL228.
Patients received oral AC220 daily for 14 days to study the side effects, tolerability and best dose for treating relapsed or refractory acute myeloid leukemia, regardless of FLT3 status.
This phase II trial is studying how well giving MS-275 together with GM-CSF works in treating patients with myelodysplastic syndrome and/or relapsed or refractory acute myeloid leukemia. MS-275 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving MS-275 together with GM-CSF may be an effective treatment for myelodysplastic syndrome and acute myeloid leukemia
In order to distinguish between clonal instability driven by imatinib in CML and actual changes with secondary clones induced by imatinib we would like to investigate the karyotype of non-CML patients treated with imatinib such as GIST patients.
Cytokine-induced killer ( CIK ) cells have been shown by our lab to be cytolytic against both autologous and allogeneic acute myeloid leukemia ( AML ) cells. Large scale expansion of CIK cells has also been shown to be feasible in healthy allogeneic stem cell donors as well as in patients undergoing mobilization for autologous transplant. Donor lymphocyte infusion (DLI) has been shown to be active against some haematological malignancies including CML, AML, MDS,NHL and Hodgkin's disease. These donor lymphocytes can be further activated in vitro to become CIK cells. At least 2 other centers in the world have given allogeneic CIK cells for patients relapsing post allogeneic transplant for a variety of haematological malignancies. These early reports have demonstrated feasibility, absence of increased GVHD and possible efficacy in some cases. We are proposing a Phase I /II study on the feasibility / efficacy of immunotherapy with allogeneic CIK cells for patients who relapse after allogeneic marrow transplant for their haematological malignancies. These patients have to be either refractory to conventional donor lymphocyte infusion, or need a larger number of donor lymphocyte than could be provided by unmanipulated donor lymphocytes. Donor lymphocytes will be collected and cultured in GMP facilities to maturity, then infused into patients. This will be given in graded doses at 4 weekly intervals and continued on in the absence of GVHD till remission is achieved or disease progression occurs. Patients may receive various forms of chemotherapy appropriate to the clinical condition in each case before the allogeneic CIK infusion. Efficacy will be assessed by comparing the response to allogeneic CIK infusion vs that to due to conventional DLI, ie response to the two different treatment using DLI response as the comparator. We expect about 10 such cases to be done over the next 3 years. Significant statistics is unlikely to be generated but observation and description of the response can generate useful information for presence or not of the efficacy of such a treatment. If clinical efficacy and superiority over conventional DLI is demonstrated, then future allogeneic CIK may take the place of DLI in this group of poor prognosis patients who relapse after allogeneic transplant .
Efforts to decrease the risk of GvHD by depleting T cells from the graft in CML patients have been complicated by an increased incidence of leukemia-relapse. Newer protocols using CD34+ selected hematopoietic cells from matched-sibling donors and subsequent infusion of T cells in incremental doses to treat or avoid relapse of disease seem to be more promising. In this study, we try to further optimize this approach by the prophylactic infusion of cytotoxic T cells activated ex-vivo against leukemia-associated/specific antigens using peptide-pulsed dendritic cells.
Study Design: prospective phase II trial with 30 patients in 1 site Treatment Scheme: Option 1: Patient < 60 years of age with relapse after chemotherapy or > 12 months after hematopoetic stem cell transplantation Mylotarg 6 mg/ m² day –21 Mylotarg 3 mg/ m² day –14 Fludarabin 30 mg/ m² day –6 to –3 TBI 2x2 Gy day –3 to –2 (total dose 8 Gy) Tacrolimus (level adapted) from day –3 on Mycophenolat 2 x 1000 mg p.o. from day 0 to day 40 PBSC day 0 Option 2: Patient > 60 years of age or younger patients < 12 Months after hematopoetic stem cell transplantation Mylotarg 6 mg/ m² day –21 Mylotarg 3 mg/ m² day –14 Fludarabin 30 mg/ m² day –3 to –1 TBI 1x2 Gy day 0 (total dose 2 Gy) Tacrolimus (level adapted) from day –3 on Mycophenolat 2 x 1000 mg p.o. from day 0 to 40 PBSC day 0
Primary Objectives: - To compare the neuropsychiatric (NP) and neurocognitive (NC) symptoms and assess the quality of life (QOL) in older patients (age > 18) with acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (MDS) receiving different therapies, chemotherapy (Clofarabine + ara-C) or targeted therapies (PKC412 + low-dose ara-C, or R115777 + low-dose ara-C, or decitabine, or STI + low-dose ara-C). - To determine whether there is a correlation between the number of packed red blood cell (PRBC) transfusions and cognitive scores and/or QOL.
This phase I trial is studying the side effects and best dose of GTI-2040 in treating patients with relapsed, refractory, or high-risk acute leukemia, high-grade myelodysplastic syndromes, or refractory or blastic phase chronic myelogenous leukemia. Drugs used in chemotherapy, such as GTI-2040, work in different ways to stop the growth of cancer or abnormal cells, either by killing the cells or by stopping them from dividing.
