Filter by:The purpose of this study is to determine the safety of darbepoetin alfa beyond 16 weeks of treatment in subjects with anemia of cancer who are not receiving chemotherapy.
This study will explore what may cause people with sickle cell anemia to have heart problems and an increased risk of sudden death. People 18 years of age and older with sickle cell anemia may be eligible for this study. Candidates are screened with a medical history and physical examination, electrocardiogram (EKG), echocardiogram (heart ultrasound), and blood tests. Participants undergo the following tests and procedures: - Holter monitoring: The patient wears a small, battery-operated device to record heart rate and rhythm over 24 to 48 hours. - QRST surface mapping: An EKG using 64 electrodes is done at rest and during exercise to provide a detailed look at the heart and its conduction system. - Chest x-rays are taken to examine the lungs. - Bicycle exercise echocardiography test: Blood pressure, pulse, heart rhythm and oxygen use are monitored while the patient exercises on a stationary bicycle. Ultrasound pictures are also obtained during the exercise. - Echocardiogram: A heart ultrasound is done to check how well the heart is pumping blood. - Pulmonary artery catheterization: A catheter (plastic tube) is inserted into a vein and advanced to the chambers of the heart, through the heart valve and into the lung artery. The pressures in the heart and lung blood vessels are measured while the patient is resting and during exercise, with the bed tilted up and down, and after giving 500 mls of fluid into a vein. - Blood tests are done to measure a hormone called brain natriuretic peptide, which can increase with the development of heart failure, and nitrite, a substance that can affect blood vessel dilation. Some blood is stored to test for inflammatory markers and for possible future gene and protein analysis. - Cardiac magnetic resonance imaging (cMRI): The patient lies in a donut-shaped magnet while pictures of the heart are obtained using a magnetic field and radio waves. Earplugs are worn to muffle the loud sounds that occur with electrical switching of the magnetic fields. A contrast agent called gadolinium may be injected to enhance the quality of the images. - Invasive electrocardiographic (reveal) monitoring: This procedure permits study of the heart rhythms over a long time period. A small device is placed just under the skin on the left side of the chest. It can be left in for up to 14 months to monitor the heartbeat continuously during this time.
This study is designed to evaluate the hemoglobin response to Aranesp® (darbepoetin alfa) in black subjects (African-Americans) with chronic renal failure (CRF) receiving hemodialysis and to examine the safety profile.
The purpose of this study is to compare the effect of darbepoetin alfa administered in a weight based versus fixed dosing for the treatment of anemia in subjects with non-myeloid malignancies receiving multicycle chemotherapy.
The purpose of the study is to see whether antimalarial drugs administered at the time of routine infant vaccinations prevents malaria and anemia in the first year of life.
The purpose of this study is to compare the effect of darbepoetin alfa against placebo for the treatment of anemia in subjects with non-myeloid malignancies receiving multicycle chemotherapy.
This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with relapsed or refractory solid tumors or myelodysplastic syndromes. Lenalidomide may stop the growth of solid tumors or myelodysplastic syndromes by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing.
Phase I trial to study the effectiveness of SB-715992 in treating patients who have acute leukemia, chronic myelogenous leukemia, or advanced myelodysplastic syndromes. Drugs used in chemotherapy, such as SB-715992, work in different ways to stop cancer cells from dividing so they stop growing or die
The purpose of this study is to evaluate the safety, pharmacokinetics (PK), and minimum pharmacologically active dose of peginesatide in Healthy Volunteers.
This phase I/II trial is studying the side effects and best dose of tipifarnib when given with idarubicin and cytarabine and to see how well it works in treating patients with newly diagnosed myelodysplastic syndromes or acute myeloid leukemia. Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Tipifarnib (Zarnestra) may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Giving idarubicin and cytarabine with tipifarnib may kill more cancer cells.
