Filter by:This study is investigating darbepoetin alfa for the treatment of anemia in patients with non-myeloid cancers who are receiving chemotherapy. Darbepoetin alfa is a recombinant protein that stimulates the production of red blood cells. In this study, darbepoetin alfa will be administered as either an injection under the skin (subcutaneously) or directly into a vein (intravenously).
RATIONALE: Cyclosporine may improve low blood counts caused by hematologic cancer. PURPOSE: Phase II trial to study the effectiveness of cyclosporine in treating patients who have low blood counts caused by hematologic cancer.
To investigate a modified hematopoeitic cell transplantation (HCT) procedure for sickle cell disease that significantly reduces the toxicity of HCT, yet retains its therapeutic benefit.
This study will develop a national cord blood bank for siblings of patients with hemoglobinopathies and thalassemia.
This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.
This study will test whether inhaling nitric oxide (NO) gas mixed with room air can improve pulmonary hypertension (high blood pressure in the lungs) in patients with sickle cell anemia. Patients with sickle cell disease 18 years of age or older may be eligible to participate in one or more parts of this three-stage study, as follows: Stage 1 Patients undergo the following tests to determine the cause of their pulmonary hypertension: blood tests; echocardiogram (heart ultrasound); asthma test; oxygen breathing study with measurement of arterial blood oxygen levels; chest X-ray; lung scans; MRI of the heart; 6-minute walk test; night-time oxygen measurement while sleeping; and exercise studies. Stage 2 Patients have a detailed MRI evaluation of the heart and are admitted to the NIH Clinical Center intensive care unit (ICU) for the following test: A plastic tube is placed in a vein in the patient's arm and another tube is placed in a deeper neck or leg vein. A third tube is inserted through the vein into the heart and the lung artery to measure blood pressures in the heart and lungs directly. Following baseline measurements, three medications (inhaled oxygen, infused prostaglandin, and inhaled NO) are delivered for 2 hours each, separated by a 30-minute washout period. A small blood sample is drawn during the NO administration. Patients who cannot be treated with nitric oxide or for whom the treatment does not work may receive monthly exchange transfusions for 3 months. For this procedure, 3 to 5 five units of the patient's blood is removed and replaced with 3 to 5 units that do not have sickle hemoglobin. Some patients who do not respond to NO or exchange transfusions may receive an alternative therapy, such as oxygen, prostacyclin, L-arginine, bosentan or sidenafil. Stage 3 Patients remain in the ICU with catheters in place for another 24 hours. During this time they breathe NO. Lung pressures are measured every 4 hours and blood is drawn every 8 hours. They then stay in the hospital 1 more day for observation. Patients then breathe nitric oxide continuously for 2 months using a tank of gas that delivers the NO through tubes placed in the nose. They may do this at home on an outpatient basis or may remain in the hospital for the 2 months. Patients have an echocardiogram and blood tests every week and do a 6-minute walk test every 2 weeks....
RATIONALE: Epoetin alfa may stimulate red blood cell production to treat patients who have anemia following chemotherapy. PURPOSE: Phase IV trial to study the effectiveness of epoetin alfa in treating chemotherapy-related anemia in women who have stage I, stage II, or stage III breast cancer.
Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Epoetin alfa may stimulate red blood cell production to treat anemia in patients who have received chemotherapy and/or radiation therapy for cervical cancer. Randomized phase III trial to study the effectiveness of epoetin alfa in treating anemia in patients who have cervical cancer.
Phase II trial to study the effectiveness of thalidomide in treating patients who have myelodysplastic syndrome. Thalidomide may improve the immune system's ability to fight myelodysplastic syndrome
Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Phase I trial to study the effectiveness of bryostatin 1 combined with sargramostim in treating patients who have refractory myeloid cancer
