Active clinical trials for "Myeloproliferative Disorders"

This randomized phase III trial studies how well graft-vs-host disease (GVHD) prophylaxis works in treating patients with hematologic malignancies undergoing unrelated donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant (PBSCT) helps stop the growth of cancer cells. It may also 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 total-body irradiation (TBI) together with fludarabine phosphate (FLU), cyclosporine (CSP), mycophenolate mofetil (MMF), or sirolimus before transplant may stop this from happening.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase III trial to study the effectiveness of combination chemotherapy in treating children who have Down syndrome and myeloproliferative disorder, acute myelogenous leukemia, or myelodysplastic syndrome.

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic bone marrow transplantation in treating patients who have multiple myeloma, chronic phase chronic myelogenous leukemia, or agnogenic myeloid metaplasia.

RATIONALE: EMD 121974 may stop the growth of cancer by stopping blood flow to the tumor. PURPOSE: Phase I trial to study the effectiveness of EMD 121974 in treating patients who have locally advanced or metastatic cancer.

RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill metastatic cancer cells. Interferon alfa may interfere with the growth of the cancer cells. Combining interleukin-2 and interferon alfa may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of interleukin-2 plus interferon alfa in treating adults with metastatic cancer.

The study consists of two phases: The first portion of the study is a Phase 1 dose escalation study to determine the maximum tolerated dose and the dose limiting toxicities of SB1518 when given as a single agent orally once daily in subjects with Chronic Idiopathic Myelofibrosis (CIMF) regardless of their JAK2 mutational status. The second portion of the study is a Phase 2 study to define the efficacy and safety profile of single agent SB1518 at the recommended dose in subjects with CIMF.

Objectives: To evaluate disease free survival after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies. To evaluate the incidence and severity of acute and chronic GVHD after Campath 1H-based in vivo T-cell depletion, in patients with hematologic malignancies undergoing non-myelo-ablative stem cell transplantation. To evaluate engraftment and chimerism after Campath 1H-based in vivo T-cell depletion and non-myelo-ablative ablative stem cell transplantation in patients with hematologic malignancies.

Allogeneic stem cell transplantation may provide long-term remissions for some patients with hematological malignancies. However, allogeneic transplantation is associated with a significant risk of potentially life threatening complications due to the effects of chemotherapy and radiation on the body and the risks of serious infection. In addition, patients may develop a condition called Graft versus host disease that arises from an inflammatory reaction of the donor cells against the recipient's normal tissues. The risk of graft versus host disease is somewhat increased in patients who are receiving a transplant from an unrelated donor. One approach to reduce the toxicity of allogeneic transplantation is a strategy call nonmyeloablative or "mini" transplants. In this approach, patients receive a lower dose of chemotherapy in an effort to limit treatment related side effects. Patients undergoing this kind of transplant remain at risk for graft versus host disease particularly if they receive a transplant from an unrelated donor. The purpose of this research study is to examine the ability of a drug called CAMPATH-1H to reduce the risk of graft versus host disease and make transplantation safer. CAMPATH-1H binds to and eliminates cells in the system such as T cells that can cause graft versus host disease (GvHD). As a result, earlier studies have shown that patients who receive CAMPATH-1H with an allogeneic transplant have a lower risk of GvHD. In the present study, we will examine the impact of treatment with CAMPATH-1H as part of an allogeneic transplant on the development of GvHD and infection. In addition, we will study the effects of CAMPATH-1H on the immune system by testing blood samples in the laboratory.

RATIONALE: Bortezomib may stop the growth of abnormal cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the abnormal cells. PURPOSE: This clinical trial is studying the side effects and how well bortezomib works in treating patients with advanced myeloproliferative disorders.

RATIONALE: Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Studying samples of cerebrospinal fluid and blood from patients with cancer in the laboratory may help doctors learn how pemetrexed disodium works in the body and identify biomarkers related to cancer. PURPOSE: This clinical trial is studying the side effects and how well pemetrexed disodium works in treating patients with leptomeningeal metastases.
