Active clinical trials for "Myeloproliferative Disorders"

RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from a related or unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow to make stem cells, red blood cells, white blood cells, and platelets. PURPOSE: This clinical trial is studying how well donor umbilical cord blood transplant works in treating patients with hematologic cancer.

This phase II trial is studying how well aflibercept works in treating patients with myelodysplastic syndromes. Aflibercept may be able to carry cancer-killing substances directly to myelodysplastic syndrome cells. It may also stop the growth of cancer cells by blocking blood flow to the cancer

RATIONALE: Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of abnormal cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well azacitidine works in treating patients with myelofibrosis.

This phase I trial is studying the side effects and best dose of decitabine in treating patients with myelodysplastic syndromes or acute myeloid leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.

Myeloproliferative neoplasms (MPNs) are a group of clonal hematologic malignancies with great variation in reported patient life expectancy and are characterized by a relatively indolent course which can be complicated by thromboembolic events and transformation to acute myeloid leukemia (AML). The MPNs in the 2016 World Health Organization (WHO) classification of myeloid neoplasms consist of polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) including prefibrotic/early stage and over fibrotic stage, chronic myeloid leukemia, other (rare) disorders such as chronic neutrophilic leukemia and chronic eosinophilic leukemia and MPN unclassifiable (MPN-U). The prevalence and genetic characteristics of patients with MPNs in Taiwan are still unknown. Molecular tests which are required for the diagnosis of MPNs are not available in many hospitals which hamper the accurate diagnosis and subtype classification of MPNs. Moreover, the information of current therapeutic strategy for MPNs in most medical centers in Taiwan is also not available. The purpose of this MPN registry is to collect clinical data, molecular characteristics, treatment details and response to therapy, occurrence of complications during the course, disease progression to secondary myelofibrosis from PV or ET and secondary AML (sAML) transformation as well as survival. The clinical and molecular data including the high molecular risk (HMR) genes will be examined and correlated with treatment outcomes in Taiwanese MPN patients. The Molecular Diagnostic Laboratory at Chang Gung Memorial Hospital-Linkou is a College of American Pathologists (CAP)-accredited lab which provides high quality of molecular genetic tests for hematologic malignancies. The three driver gene mutations are the major criteria for the diagnosis of MPN, the methodologies of mutational analyses have been well set up for the clinical use in this lab. In addition, this lab is also equipped with facilities for the detection of mutated genes which were recently identified as HRM category (presence of any of ASXL1, EZH2, SRSF2, IDH1 or IDH2), and mutations of other epigenetic regulators or splicing factors.

This phase I/II trial studies how well Jaktinib and azacytidine work in treating patients with myelodysplastic syndromes with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm with myelofibrosis. Giving Jaktinib and azacytidine may be an effective treatment for myelodysplastic syndromes with myelofibrosis or myelodysplastic syndrome/myeloproliferative neoplasm with myelofibrosis.

The goal of this clinical research study is to learn if giving pacritinib before standard of care drugs followed by an allogeneic stem cell transplant can help to control myeloproliferative neoplasms. The safety of this therapy will also be studied.

The goal of this clinical research study is to learn if giving genetically changed immune cells, called T-cells, after chemotherapy will improve the response to a stem cell transplant. The safety of this treatment will also be studied. The process of changing the DNA (the genetic material in cells) of these T-cells is called "gene transfer." Researchers want to learn if these genetically-changed T-cells are effective in attacking cancer cells in patients with leukemia, MDS, lymphoma, Hodgkin disease, or MM, after they have received an allogeneic stem cell transplant. The chemotherapy you will be given on study is fludarabine, melphalan, and alemtuzumab. These drugs are designed to stop the growth of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's stem cells. Researchers also want to learn if giving AP1903 will help the symptoms of graft-versus-host disease (GvHD) that may occur after the T-cell infusion. GvHD occurs when donor cells attack the cells of the person receiving the stem cell transplant.

The goal of this clinical research study is to learn what dose of a kind of immune cell called T-lymphocytes (T-cells) given as a donor infusion about 8-9 weeks after a stem cell transplant has the best results. The safety of this treatment will also be studied. This will be tested in patients with leukemia, MDS, lymphoma, Hodgkin disease, and multiple myeloma. These results are measured as helping to control the disease without severe graft-versus-host disease (GvHD). GvHD is when transplanted donor tissue attacks the tissues of the recipient's body. Fludarabine, melphalan, and alemtuzumab are commonly given before stem cell transplants: Fludarabine is designed to interfere with the DNA (genetic material) of cancer cells, which may cause the cancer cells to die. Melphalan is designed to bind to the DNA of cells, which may cause cancer cells to die. Alemtuzumab is designed to weaken the immune system and reduce the risk of rejection of the transplant and graft-vs-host disease (GvHD). The donor infusion of T-cells is designed to help restore the immune system after the transplant, cause an immune reaction against the cancer, and reduce the risk of the cancer coming back.

RATIONALE: Giving total marrow and total lymph node irradiation together with low doses of chemotherapy 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). PURPOSE: This phase I trial is studying the side effects and best dose of total marrow and total lymph node irradiation when given together with fludarabine and melphalan followed by donor stem cell transplant in treating patients with advanced hematological cancer that has not responded to treatment.
