Filter by:The purpose of this study is to evaluate the effects of cinacalcet (cinacalcet HCl or Sensipar®/Mimpara®) on cardiovascular events and death in chronic kidney disease (CKD) patients with secondary hyperparathyroidism (HPT) who are receiving dialysis.
This is a randomized, open-label, parallel-design study to be conducted at 75 centers within the United States. The study will be described to hemodialysis patients. Informed consent will be obtained and the inclusion/exclusion criteria reviewed. Eligible patients will be randomized to receive either Renagel or a calcium-based binder. Starting from the randomization date, mortality data including survival, death date and cause of death (vital status information) and morbidity data including hospitalization date will be recorded for all patients. These data will be collected until the end of the study (December 31, 2004, ± 2 weeks). Patients completing or terminating from the study will return to the phosphate binder prescribed by their usual healthcare provider.
A randomized, cross-over, open-label study will be conducted to evaluate the equivalency, safety and tolerability of sevelamer once per day dosing, given with the largest meal, compared with standard three times per day dosing, in hemodialysis patients previously using sevelamer. Following a two week Run-In period, a total of 24 patients will be randomized to one of the following treatment sequences: 1. sevelamer dosed once a day with the largest meal followed by standard three times per day dosing with meals 2. sevelamer dosed three times per day with meals followed by once a day dosing with the largest meal. Patients will maintain a fixed daily dose throughout both treatment periods based on the most recently prescribed sevelamer dose prior to screening.
The purpose of this study is to evaluate the ability of peginesatide (AF37702) to increase and maintain increased hemoglobin levels in participants with chronic kidney disease (CKD) (either not on dialysis, receiving regular hemodialysis or peritoneal dialysis, or following renal transplant) with confirmed antibody-mediated pure red cell aplasia (PRCA).
Oxidative stress and acute phase inflammation are now recognized to be highly prevalent in both the chronic kidney disease (CKD; pre-dialysis) and end stage renal disease (ESRD; on hemodialysis) populations, and several lines of evidence point to their contribution in the development of atherosclerosis. Biomarkers of the inflammatory state such as C-reactive protein (CRP) and interleukin-6 are robust predictors of cardiovascular events and death in these two populations. The uremic state is characterized by retention of oxidized solutes including reactive aldehyde groups and oxidized thiol groups. It has recently been demonstrated that initiation of maintenance hemodialysis does not improve biomarkers of oxidative stress or inflammation, suggesting that dialysis alone is inadequate to control the atherosclerotic uremic metabolic state. In this study we hypothesize that administration of antioxidant therapy will decrease biomarkers of acute phase inflammation and oxidative stress in patients with Stage III and IV CKD.
Patients with kidney failure have a poor survival rate that is due to a much higher than average rate of heart and vascular disease. The reason that kidney failure causes heart disease is unknown but recent research suggests that a hormone called aldosterone, which is increased in patients with kidney disease may damage the heart and blood vessels. The investigators propose, using a randomized blinded trial, to find out whether drugs that inhibit the actions of aldosterone have beneficial effects on the cardiovascular system in patients with kidney failure
This study will examine the use of hydroxyurea and erythropoietin for treating sickle cell disease in patients who also have kidney disease or pulmonary hypertension (high blood pressure in the lungs). Hydroxyurea increases production of fetal hemoglobin in the red blood cells of patients with sickle cell disease, reducing the amount of sickle cells that cause pain and other complications requiring hospitalizations. However, hydroxyurea treatment has limitations: patients with sickle cell disease who have developed kidney disease may not be able to get the full benefit of the medicine, and hydroxyurea alone may not be able to treat life-threatening complications such as pulmonary hypertension or stroke. This study will determine which of two dosing schedules of hydroxyurea and erythropoietin is more effective for treating patients with sickle cell disease who also have kidney disease or pulmonary hypertension, and will examine whether the two drugs can lower blood pressure in the lungs. Patients 18 years of age and older with sickle cell anemia and kidney disease or pulmonary hypertension, or both, may be eligible for this study. Candidates are screened with a medical history, physical examination, blood tests, a 6-minute walk test (test to see how far the subject can walk in 6 minutes), and echocardiogram (ultrasound of the heart to measure blood pressure in the lungs). Participants undergo the following tests and procedures: Stabilization Phase: Patients take 2 hydroxyurea tablets a day until their fetal hemoglobin levels stabilize, usually over 2 to 4 months. They have blood tests every 2 weeks to monitor hemoglobin and fetal hemoglobin levels. At some time during this period, they undergo a test to measure kidney function, in which they are injected with an iodine-containing dye and wear a small pump for 1 day that injects a small amount of dye under the skin over 24 hours. They come to the clinic for 2 or 3 blood tests collected over 4 hours. Sequence I (Standard): When the fetal hemoglobin levels have been stable for 2 months, patients have a repeat echocardiogram and 6-minute walk test. Erythropoietin is then added to the hydroxyurea regimen. It is given 3 days a week, as an injection under the skin, along with iron supplements. Patients have blood tests and blood pressure measurements every week or every other week. Patients with pulmonary hypertension have another echocardiogram and 6-minute walk test once the hemoglobin level is stable. Sequence II (Cycled): When hemoglobin levels have stabilized with hydroxyurea once a day and erythropoietin 3 times a week, the hydroxyurea is adjusted so that the amount taken in 7 days is "cycled" over 4 days, and the erythropoietin is cycled over 3 days, with the dose increased twice, every 3 to 4 weeks. Blood pressure and hemoglobin are monitored once or twice a month. Patients with pulmonary hypertension have another echocardiogram and 6-minute walk test once the hemoglobin level is stable. Patients who develop complications while taking the drugs have their treatment regimens adjusted as needed.
The purpose of this study is to determine if sevelamer carbonate powder is an effective treatment for the control of serum phosphorous levels in patients on dialysis when compared to sevelamer hydrochloride tablets.
The study is being performed to better understand dialysis techniques which keep heart functions stable during dialysis. People on dialysis have a high risk for heart disease and strokes. More information about dialysis techniques that keep hearts stable may help prevent the high risk of cardiovascular disease and death and help to reduce discomfort during dialysis. This study will look at the way that the magnesium in dialysate affects heart function during dialysis. High or low levels of magnesium may change the way hearts beat. The question asked is if lowering the amount of magnesium in dialysate will affect the amount of magnesium in blood or change the heart beat.
