Active clinical trials for "Preleukemia"

This phase IIa trial studies the side effects of itacitinib when given together with standard treatment (tacrolimus and sirolimus), and to see how well it works in preventing graft-versus-host-disease (GVHD) in patients with acute leukemia, myelodysplastic syndrome or myelofibrosis who are undergoing reduced intensity conditioning donor stem cell transplantation. GVHD is a common complication after donor stem cell transplantation, resulting from donor immune cells recognizing recipients' cells and attacking them. Adding itacitinib to tacrolimus and sirolimus may reduce the risk GVHD and ultimately improve overall outcome and survival after donor stem cell transplantation.

This phase I trial studies the side effects and best dose of ipilimumab when given together with decitabine in treating patients with myelodysplastic syndrome or acute myeloid leukemia that has returned after a period of improvement (relapsed) or does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ipilimumab and decitabine may work better in treating patients with relapsed or refractory myelodysplastic syndrome or acute myeloid leukemia.

Myelodysplastic syndromes (MDS) prevail in older age and are characterized by ineffective erythropoiesis and peripheral cytopenias. Supportive therapy is the main therapeutic option for most patients. Quality of Life (QoL) is mainly deteriorated by anemia and by the limitations associated with thrombocytopenia, neutropenia and transfusion dependence. The only available treatment for severe thrombocytopenia, in the presence of bleeding, is platelet transfusion. Eltrombopag is an orally bioavailable agonist of the thrombopoietin receptor. In adult patients with chronic immune thrombocytopenia (ITP), Eltrombopag rapidly increases platelet counts and significantly reduces bleeding episodes during treatment. Eltrombopag is well tolerated. In 2007, Eltrombopag has received the Orphan Drug Designation for the treatment of ITP (EMEA/OD/031/07), and in 2008 the Food and Drug Association approved Eltrombopag for the treatment of ITP refractory or resistant. It has been shown that in patients affected by MDS and by acute myeloid leukemia, Eltrombopag neither increases the proliferation, nor the clonogenic growth capacity of bone marrow blasts. Furthermore, Eltrombopag induces an increase in the megakaryocytic differentiation and in the formation of normal megakaryocytic colonies. These results provide the rationale for pursuing further research on Eltrombopag for the treatment of thrombocytopenia in case of MDS. The study is open to adult patients with myelodysplastic syndrome (MDS) with thrombocytopenia and low- or intermediate-1 IPSS risk (Index Prognostic Score System). Severe thrombocytopenia associated with MDS may lead to death from hemorrhage, even in low prognostic risk patients. The benefit of platelet transfusion is short-termed. Patients become refractory in the long term. The availability of a treatment that induces the increase of platelet count is extremely important, either in terms of quality of life, and in overall survival.

This phase I trial studies the side effects and best dose of total bone marrow and lymphoid irradiation when given together with chemotherapy before donor stem cell transplant in treating patients with myelodysplastic syndrome or acute leukemia. Total marrow and lymphoid irradiation is a type of radiation therapy that targets bone marrow and blood, where the cancer is, instead of applying radiation to the whole body. Stem cell transplants use high doses of chemotherapy and radiation therapy, such as total marrow and lymphoid irradiation, to kill cancer cells, but these treatments kill normal cells as well. After chemotherapy, healthy cells from a donor are given to the patient to help the patient grow new blood cells.

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral stem cell transplant helps stop the growth of cancer or abnormal cells. It also helps stop the patient's immune system from rejecting the donor's stem 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 tacrolimus, methotrexate, cyclosporine, mycophenolate mofetil, and sirolimus before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor peripheral stem cell transplant works in treating patients with advanced hematologic cancer or other disorders.

The purpose of this study is to determine the activity of SY-1425 in relapsed/refractory acute myeloid leukemia (AML) patients (SY-1425 administered as a monotherapy or in combination with azacitidine), relapsed/refractory higher-risk myelodysplastic syndrome (MDS) patients (SY-1425 administered as a monotherapy or in combination with daratumumab), newly diagnosed treatment naïve AML patients who are unlikely to tolerate standard intensive chemotherapy (SY-1425 administered as a monotherapy or in combination with azacitidine), or lower-risk myelodysplastic syndrome (MDS) patients (SY-1425 administered as a monotherapy).

This phase IIa trial studies how well guadecitabine works in treating patients with acute myelogenous leukemia and myelodysplastic syndrome that has returned after a period of improvement after allogeneic stem cell transplant. Guadecitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving guadecitabine before the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

This phase II trial studies how well guadecitabine works in treating patients with myelodysplastic syndromes that are at higher risk for becoming acute myeloid leukemia. Guadecitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Evaluation of the Efficacy and Safety of Oral Azacitidine plus Best Supportive care versus Placebo and Best Supportive care in subjects with red blood cell (RBC) transfusion-dependent anemia and thrombocytopenia due to International Prognostic Scoring System (IPSS) lower risk myelodysplastic syndromes (MDS).

Patients will be receiving a stem cell transplant as treatment for their disease. As part of the stem cell transplant, patients will be given very strong doses of chemotherapy, which will kill all their existing stem cells. A close relative of the patient will be identified, whose stem cells are not a perfect match for the patient's, but can be used. This type of transplant is called "allogeneic", meaning that the cells are from a donor. With this type of donor who is not a perfect match, there is typically an increased risk of developing GvHD, and a longer delay in the recovery of the immune system. GvHD is a serious and sometimes fatal side-effect of stem cell transplant. GvHD occurs when the new donor cells (graft) recognize that the body tissues of the patient (host) are different from those of the donor. In this study, investigators are trying to see whether they can make special T cells in the laboratory that can be given to the patient to help their immune system recover faster. As a safety measure, we want to "program" the T cells so that if, after they have been given to the patient, they start to cause GvHD, we can destroy them ("suicide gene"). Investigators will obtain T cells from a donor, culture them in the laboratory, and then introduce the "suicide gene" which makes the cells sensitive to a specific drug called AP1903. If the specially modified T cells begin to cause GvHD, the investigators can kill the cells by administering AP1903 to the patient. We have had encouraging results in a previous study regarding the effective elimination of T cells causing GvHD, while sparing a sufficient number of T cells to fight infection and potentially cancer. More specifically, T cells made to carry a gene called iCasp9 can be killed when they encounter the drug AP1903. To get the iCasp9 gene into T cells, we insert it using a virus called a retrovirus that has been made for this study. The AP1903 that will be used to "activate" the iCasp9 is an experimental drug that has been tested in a study in normal donors with no bad side-effects. We hope we can use this drug to kill the T cells. The major purpose of this study is to find a safe and effective dose of "iCasp9" T cells that can be given to patients who receive an allogeneic stem cell transplant. Another important purpose of this study is to find out whether these special T cells can help the patient's immune system recover faster after the transplant than they would have otherwise.
