Filter by:This clinical study is being conducted at multiple sites to determine the activity, safety and tolerability of XL999 when given weekly to patients with relapsed or newly-diagnosed AML. XL999 is a small molecule inhibitor against Flk1/kinase insert domain receptor (KDR), PDGFR, c-Kit, FLT3 and SRC. c-Kit and FLT3 are receptors commonly expressed on AML blasts.
The purpose of this study is to compare the efficacy of dasatinib with that of high-dose (800-mg) imatinib in participants with chronic phase chronic myeloid leukemia who achieved only a suboptimal response after at least 3 months of monotherapy with 400-mg imatinib. The safety of these treatments will also be evaluated.
T-cell and B-cell depletion in allogeneic peripheral blood stem cell transplantation by using immunomagnetic negative and positive selection procedures Background: Removal of T-cells from the donor graft (T-cell depletion) offers the possibility for prevention of GVHD and subsequently less transplant related morbidity and mortality after allogeneic stem cell transplantation (SCT). There are several techniques to deplete T-cells from the stem cell grafts e.g. physical, immunological and combined physical / immunological separation methods. All these techniques result in a stem cell graft with sufficient CD34+ stem cells combined with an adequate depletion of T and B cells. CD34+ selected stem cell grafts are very pure and do not contain any additional cell populations. In contrast, CD3+/CD19+ depleted grafts still contain NK-cells, monocytes and dendritic cells that are part of the innate immune system. Theoretically,the presence of these cells may positively influence immunological reconstitution and the graft-versus-leukaemia (GVL) effect, respectively, resulting in improved outcome after SCT Objectives: To evaluate the differences in immunological reconstitution, transplant related mortality, disease-free survival and overall survival after T-cell depleted allogeneic SCT for haematological malignancies using either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion using the CliniMACS system in approximately 270 consecutive patients. Additionally in this study in 20 consecutive patients the kinetics of NK-cel reconstitution and differences in NK-cell repertoire will be monitored. NK-cell mediated anti-tumor reactivity will be monitored in patients transplanted with and without NK-cells in the stem cell graft (CD3+/CD19+ depletion, versus CD34+ selection). Secondary objectives are to evaluate the clinical relevance of minor histocompatibility-specific cytotoxic T-cell responses for the GVL effect, the kinetics of NK-cell reconstitution and differences in NK-cell repertoire using the different T-cell depletion protocols. Design: Single center prospective randomised phase III study Population: Patients eligible for allogeneic SCT according to the standard criteria of our institution who will receive an allogeneic T- and B-cell depleted SCT with peripheral stem cells of an HLA-identical sibling donor or an HLA-identical unrelated voluntary (VUD) donor. Intervention: T-cell depletion will be conducted using two different techniques: either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion. Endpoints: Primary endpoints are immunological reconstitution, relapse, disease free survival and overall survival. Secondary endpoints: NK-cell reconstitution and NK-cell mediated anti-tumour reactivity. Cytotoxic T-cell responses for the GVL effect. Estimated efforts and risks for participating patients: We don't expect any extra patient efforts or risks because T-cell depletion is a standard procedure in our clinic for many years. There is extensive experience with immunological T-cell depletion techniques. We hypothesize CD3+/CD19+ depletion will favour stem cell transplant outcome. Immunological and molecular biological studies will be performed on blood samples already obtained as part of the standard protocol.
This phase I trial is studying the side effects and best dose of SJG-136 in treating patients with relapsed or refractory acute leukemia, myelodysplastic syndromes, blastic phase chronic myelogenous leukemia, or chronic lymphocytic leukemia. Drugs used in chemotherapy, such as SJG-136, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
The primary objective is to determine the maximum tolerated dose (MTD), dose limiting toxicity (DLT), and safety profile of TKI258 when administered to subjects with acute myeloid leukemia (AML).
RATIONALE: Drugs used in chemotherapy, such as gemcitabine and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving gemcitabine together with mitoxantrone works in treating patients with relapsed acute myeloid leukemia.
Imatinib mesylate is standard treatment of Chronic myeloid leukaemia, complete cytogenetic response is obtained in most of cases but molecular response concerned only a small part of the patients. To increase molecular response ratio we decided to increase imatinib dose to limited resistance to this drug and to add zoledronate for it anti tumoral activity to increase anti leukemic effect. We plan to accrue 37 patients in 5 centers. We will analyse molecular expression of BCR-ABL transcript after 6 months of treatment, safety, duration of response, VEGF expression and LTgd production.
To assess the proportion of patients with donor neutrophil engraftment within 30 days of allogeneic transplant. To assess the incidence of acute GvHD during the first 100 days after transplantation.
The purpose of the study is to evaluate the overall and disease free survival of recipients who have received G-CSF mobilized stem cells from HLA matched sibling donors.
This clinical research study is for patients with acute myelogenous leukemia (in short AML) that did not respond to previous treatment or unable to receive chemotherapy. Arsenic has been used as a drug for many centuries. While arsenic containing drugs were used in the past for cancer treatments, the major use of arsenic in western countries has been for the treatment of uncommon tropical illnesses, such as sleeping sickness. Recently, some new information suggests that arsenic in a form called arsenic trioxide may also be useful to treat some cancers of the blood, such as leukemia, lymphoma and myeloma. Studies from China and the USA showed that patients with a type of blood cancer called acute promyelocytic leukemia, whose disease failed to respond to other treatments, responded very well to arsenic trioxide. Studies done in laboratories in the United States have shown that arsenic can kill AML cells growing in culture dishes. Ascorbic acid (vitamin C), a natural supplement in our diet, has long been involved with cancer prevention. Laboratory tests have shown that although arsenic trioxide by itself can kill AML cells in the test tube, when vitamin C is added to arsenic trioxide in a test tube, the death of the leukemia cells increases significantly. The purpose of this study is to find out if the combination of arsenic trioxide (Trisenox) and ascorbic acid is effective in the treatment of patients who have AML. The second purpose is to study how the two drugs affect cells in the laboratory. Samples from the blood and bone marrow (the part of the body that makes blood cells) will be collected, at specific times during treatment, in order to study them in the laboratory. By studying blood and marrow cells, researchers hope to learn the mechanisms by which the drugs work.
