Active clinical trials for "Myeloproliferative Disorders"

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral stem cell 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 donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. PURPOSE: This phase II trial is studying how well peripheral stem cell transplant works in treating patients with high-risk leukemia.

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying the side effects of imatinib mesylate and how well it works in treating patients with myelofibrosis.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: This phase I trial is studying the side effects and best dose of 12-O-tetradecanoylphorbol-13-acetate in treating patients with hematologic cancer or bone marrow disorder that has not responded to previous treatment.

RATIONALE: Bone marrow transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Eliminating the T cells from the donor cells before transplanting them may prevent this from happening. PURPOSE: Phase II trial to study the effectiveness of T cell removal to prevent graft-versus-host disease in patients who are undergoing bone marrow transplantation from a donor.

This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. This study may provide critical information for medical decision-making and possible immunotherapy interventions in immunocompromised transplant recipients, who are at high risk for COVID19 severe illness.

This prospective, multicenter, randomized, open-label, Phase 2, parallel, dose ranging, multidose trial will enroll patients into 3 Thrombosomes dose groups and 1 control liquid stored platelets (LSP) group in order to evaluate, in a dose-escalation manner, the safety, and impact on bleeding, and the preliminary effect on coagulation measures of increasing doses of allogeneic Thrombosomes in comparison to standard of care, LSP.

This phase I trial studies the side effects and best dose of recombinant EphB4-HSA fusion protein when given together with cytarabine or vincristine liposomal in treating participants with acute leukemia that has come back or has not responded to treatment. Drugs used in chemotherapy, such as recombinant ephb4-HSA fusion protein, cytarabine, and vincristine liposomal, 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 the drugs in different combinations may kill more cancer cells.

RATIONALE: Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying the side effects and how well low-dose decitabine works in treating patients with symptomatic myelofibrosis.

RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer or abnormal 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 cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well donor umbilical cord blood transplant with reduced intensity conditioning works in treating patients with advanced hematological cancer or other disease.

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.
