Active clinical trials for "Myeloproliferative Disorders"

Patients are being asked to participate in this study because they have a malignant blood disease such as Myelodysplastic Syndrome (MDS), Myeloproliferative Disorder (MPD), Acute Myelogenous Leukemia (AML) or Chronic Myelogenous Leukemia (CML). We feel that patients could benefit from an allogeneic (meaning the cells come from a donor other than themself) stem cell transplant. The donor would be a family member or an unrelated person that is felt to be a good match for the patient. Stem cells are cells that are made in the bone marrow (spongy material that fills the middle of the bones). As the stem cells grow, they change into different types of blood cells that they need. This includes red blood cells that carry oxygen around the body, white blood cells that help to fight infections, and platelets that help to prevent and stop bleeding. Usually, patients are given high doses of chemotherapy before a stem cell transplant. High doses of chemo destroy the bone marrow. Healthy stem cells from a donor are then given to replace the patient's unhealthy cells. However, because of complications with the patient's disease, they have a high risk of having life-threatening side effects. These include serious damage to organs such as the lung, liver, kidney and heart. There is also an increased risk of bacterial, fungal, and viral infections. The other major problem is when a donor's stem cells (also called the graft) find that the patient's cells ( the host cells) are not the same. The donor cells may try to destroy the host's cells. The cells at high risk are those of the skin, liver and intestines. This is called graft versus host disease (GVHD) and it can be fatal. Recently, doctors have been able to use less toxic chemotherapy treatments before patients receive their transplants. This less toxic treatment helps reduce some of the treatment related problems mentioned above. Patient's are being asked to be involved in a research study that uses this approach. One major risk of this low dose treatment is that the patient's body may reject the donor cells. This is called graft rejection. This study is designed to see if this low dose treatment is safe and effective. This treatment plan adds CAMPATH 1H (a special protein called an antibody) to a low dose chemotherapy regimen. After chemo, the patient will receive an allogeneic (cells come from a donor) stem cell transplant. Adding CAMPATH 1H to the transplant medicines may help in treating the disease. CAMPATH 1H may reduce life-threatening and treatment related side effects like GVHD. CAMPATH 1H stays active in the body for a long time which means it may work longer to prevent GVHD. CAMPATH 1H destroys lymphocytes, a type of white cells that help fight infection, and this helps prevent graft rejection. We want to see if the addition of CAMPATH 1H to the patient's pre-transplant low dose chemotherapy will decrease the side effects from an allogeneic stem cell transplant, while providing a curative treatment for patients with blood 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: 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.

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.

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 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 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: 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: 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.

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.
