Active clinical trials for "Leukemia, Myeloid, Acute"

Evaluate the safety and tolerability of AMG 397. Estimate the maximum tolerated doses (MTDs) and/or biologically active doses.

Successful treatment for children and young adults with relapsed acute myeloid leukemia (AML) continues to be a significant challenge. Despite relative improvements in survival for patients with newly diagnosed AML, an estimated 40-60% will relapse with the majority eventually dying of their relapsed disease. Attaining a subsequent remission in patients who relapse is the initial critical step toward achieving a potential cure. As chemotherapy resistance is one of the primary drivers of poor treatment response and subsequent relapse in AML, identifying methods to reverse this resistance are desperately needed. This clinical trial is aimed at improving the remission re-Induction rates for children and adults with relapsed or refractory AML through epigenetic modifying agents that have the ability to reverse chemotherapy resistance. Decitabine, a DNA methyltransferase inhibitor (DNMTi) and Vorinostat, a histone deacetylase inhibitor (HDACi), are two epigenetic modifying drugs that act on the methylation of proximal promoter regions of genes and on proteins involved in the wrapping of DNA around histones, respectively. Both processes play a critical role in regulating gene expression, and frequently these genes are involved in chemotherapy resistance. These agents are FDA-approved for treatment in adult hematologic malignancies, making this an opportune time to begin testing these novel therapies in pediatric leukemia trials. This study will investigate chemotherapy priming of relapsed/refractory AML using Decitabine and Vorinostat given for 5 days prior to standard re-Induction with Fludarabine, Cytarabine and G-CSF for children and adults.

RATIONALE: Drugs used in chemotherapy, such as clofarabine and daunorubicin, 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 daunorubicin may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving clofarabine together with daunorubicin works in treating older patients with newly diagnosed acute myeloid leukemia.

This phase II trial is studying how well rituximab works in preventing acute graft-versus-host disease (GVHD) in patients undergoing a donor stem cell transplant for hematologic cancer. Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop 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 a monoclonal antibody, rituximab, together with anti-thymocyte globulin, tacrolimus, and mycophenolate mofetil before and after the transplant may stop this from happening

The purpose of this study is to investigate the combination of gemtuzumab ozogamicin, mitoxantrone and etoposide as second line therapy in patients with acute myeloid leukemia.

RATIONALE: Vorinostat may stop the growth of cancer cells by interfering with various proteins needed for cell growth. Monoclonal antibodies, such as gemtuzumab ozogamicin (GO), can block cancer growth in different ways. GO finds cancer cells and helps kill them by carrying a cancer-killing substance to them. Giving vorinostat together with gemtuzumab ozogamicin may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving vorinostat together with gemtuzumab ozogamicin works in treating older patients with previously untreated acute myeloid leukemia.

The purpose of the Phase I portion of this study is to evaluate the safety of this combination of medications and to determine the appropriate dose of VNP40101M to be used in combination with infusional cytarabine (araC) in elderly patients with Acute Myeloid Leukemia (AML) and High Risk Myelodysplastic Syndrome (MDS). The purpose of the Phase II portion of the study is to evaluate the effectiveness (overall response rate) for patients treated with VNP40101M and infusional cytarabine induction therapy.

The primary purpose of this study is to find out what the maximum tolerated dose is for an experimental drug called AZD4877 based on the side effects experienced by patients that receive AZD4877 on a daily times 3 schedule in acute myelogenous leukemia (AML).

This phase I trial studies the side effects and best dose of iodine I 131monoclonal antibody BC8 when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, and donor bone marrow transplant, and to see how well they work in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia that has spread to nearby or other places in the body (advanced), or high-risk myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. Also, radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide together with mycophenolate mofetil and tacrolimus after the transplant may stop this from happening. Giving a radiolabeled monoclonal antibody together with donor stem cell transplant, fludarabine phosphate, cyclophosphamide, mycophenolate mofetil, and tacrolimus may be an effective treatment for advanced acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes.

Blood disorders such as leukemia or lymphoma or hemoglobinopathies can benefit from receiving an allogeneic (meaning that the cells are from a donor) stem cell transplant. Stem cells are created in the bone marrow. They grow into different types of blood cells that the body needs, including red blood cells, white blood cells, and platelets. In a transplant, the body's stem cells would be killed and then replaced by stem cells from the donor. Usually, patients are given very high doses of chemotherapy (drugs which kill cancer cells) prior to receiving a stem cell transplant. However, patients that are older, have received several prior treatments, or have other organ diseases are at a high risk of getting life-threatening treatment-related side effects from high doses of chemotherapy. Over the past several years, some doctors have begun to use lower doses of chemotherapy for preparing patients for a stem cell transplant. A condition that can occur after a stem cell transplant from a donor is Graft Versus Host Disease (GVHD). It is a rare but serious disorder that can strike persons whose immune system is suppressed and have received either a blood transfusion or a bone marrow transplant. Symptoms may include skin rash, intestinal problems similar to inflammation of the bowel and liver dysfunction. This research study uses a combination of lower-dose chemotherapy agents that is slightly different from those that have been used before. The medicines that will be used in this study are Fludarabine, Busulfan, both chemotherapy medicines, and Campath. Campath is a monoclonal antibody (a type of substance produced in the laboratory that binds to cancer cells). It helps the immune system see the cancer cell as something that needs to be destroyed. This research study will help us learn if using Fludarabine, Busulfan and Campath prior to an allogeneic stem cell transplant can provide treatment for blood disorders while decreasing the incidence of side effects.
