Active clinical trials for "Leukemia"

Association group of therapeutic specialities authorized in a remission induction treatment(FLAG-IDA: fludarabine, cytarabine, G-CSF (lenograstim) and idarubicin) and an intensive postremission treatment with authorized therapeutic association specialities and with/without Autologous Hemopoietic Stem Cell Transplantation or Bone Marrow Transplantation in Patients With High Risk Myelodysplastic Syndromes or Secondary Acute Myeloblastic Leukemia.

The study is designed with drugs used frequently in the treatment of AML, but with a new combination less toxic,and effective in AML multidrug resistant. Justification: The AML patients with primary resistance or relapsed in the first 12 months after CR, have second line chemotherapy low response rate . These patients with AML with primary resistance or relapse, that reach remission after a rescue treatment, have an interval free survival and a global survival very short Probably the resistance to the treatments is in relation to different forms expression of the MDR. Complete remission is considered valid evaluation, because every patient who should obtain a CR can be considered to be eligible for a possible curative treatment: Ara-C administration to high doses or the TPH treatment

The Phase 1 portion of the study will evaluate the pharmacokinetic profile and safety of ABT-263 under two different dosing schedules with the objective of defining the dose limiting toxicity and maximum tolerated dose. The Phase 2a portion of the study will evaluate ABT-263 at the defined recommended Phase 2 dose to obtain additional safety information and a preliminary assessment of efficacy. The Extension Study portion will allow active subjects to continue to receive ABT-263 for up to 11 years after the last subject transitions with less frequent study evaluations.

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.

RATIONALE: Drugs used in chemotherapy, such as clofarabine, topotecan, vinorelbine, thiotepa, and dexamethasone, 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 I trial is studying the side effects and best dose of clofarabine when given together with topotecan, vinorelbine, thiotepa, and dexamethasone in treating young patients with relapsed or refractory acute leukemia.

RATIONALE: ABT-888 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Collecting and storing samples of blood from patients with cancer to study in the laboratory may help doctors learn more about the ways a patient's body handles the drug. PURPOSE: This early phase I trial is studying the side effects and best dose of ABT-888 in patients with refractory solid tumors or hematologic cancer.

RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide and fludarabine, total-body irradiation, and rituximab before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving chemotherapy and radiation therapy together with rituximab and an umbilical cord blood transplant works in treating patients with B-cell non-Hodgkin's lymphoma.

RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill cancer cells. Biological therapies, such as GM-CSF, may stimulate the immune system in different ways and stop cancer cells from growing. Giving vaccine therapy together with GM-CSF may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects of vaccine therapy and GM-CSF in treating patients with acute myeloid leukemia, myelodysplastic syndromes, non-small cell lung cancer, or mesothelioma.

Acute myeloid leukemia (AML) is a heterogeneous group of diseases characterized by uncontrolled proliferation of the myeloid line of white blood cells and impaired production of normal blood cells. If untreated, patients die of infection or bleeding usually in a matter of weeks. CSL360 is a neutralising monoclonal antibody which is believed to target the cells that are thought to drive AML but that are not effectively killed by standard treatment. The aims of the study are to determine a biologically active dose of CSL360 and generate understanding of a rational schedule of administration for future studies.

RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase II trial is studying how well vaccine therapy works in treating patients with Philadelphia chromosome-positive chronic myelogenous leukemia.
