Filter by:Secondary Hyperparathyroidism (SHPT) occurs in many patients with kidney disease and leads to bone disease. Active forms of vitamin D, calcitriol and paricalcitol, treat SHPT, but may have different effects on blood calcium. This study will randomize patients with SHPT and stage 3 or 4 CKD to treatment with calcitriol or paricalcitol, and monitor patients for the incidence of high blood calcium, and effectiveness of SHPT treatment.
Randomized Trial to Evaluate the Efficacy and Safety of Cinacalcet Treatment in Combination with Low Dose Vitamin D for the Treatment of Subjects with Secondary Hyperparathyroidism (SHPT) Recently Initiating Hemodialysis
The purpose of this study is to determine whether oral paricalcitol is safer and more efficacious compared to oral calcitriol in the treatment of hyperparathyroidism in chronic kidney disease patients undergoing dialysis.
This study will compare CTAP201 with Doxercalciferol in patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT), undergoing regular hemodialysis, at different dose strengths. This study will also investigate the levels of CTAP201 in the body over time and determine the safety of CTAP201.
This study will evaluate whether earlier intervention with vitamin D in stage II/III chronic kidney disease will prevent or delay secondary hyperparathyroidism. Subjects will receive vitamin D or placebo at study entry and will be followed for a period of one year. The hypothesis is that subjects given vitamin D will have lower PTH and higher 25(OH)D after 1 year compared to placebo. Additionally, there will be less subjects who progress into secondary hyperparathyroidism in the vitamin D treated group compared to the placebo treated group.
The purpose of this study is to determine if a reduction in the enzyme 1-hydroxylase, which activates Vitamin D, is the cause of overactivity of the parathyroid glands (called secondary hyperparathyroidism - normal blood calcium and elevated parathyroid hormone) in a selected group of young patients with normal kidney function.
A prospective, randomized, controlled multicenter trial to evaluate 1.25 mmol/L (physiological) vs. 1.5 mmol/L calcium dialysate on serum markers of mineral metabolism, secondary hyperparathyroidism and cardiovascular calcification in prevalent haemodialysis patients. And the long term safety of the 1.25 mmol/L calcium dialysate was also considered. There are two phases of study for each subject. Phase 1 (screening phase). During this phase, each potential subject will be evaluated to determine if he/she is eligible for the study. Phase 2 (intervention phase). Each subject will be randomly allocated to physiological calcium dialysate (1.25 mmol/L calcium dialysate) group (PCD group), and normal calcium dialysate (1.5 mmol/L calcium dialysate) group (NCD group). The follow-up duration was 36 months.
This study will investigate the levels of CTA018 in the body over time (pharmacokinetics, PK) in patients with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT), undergoing regular hemodialysis. This study will also investigate the safety and effects of different strengths of CTA018, on parathyroid hormone (PTH) levels.
The purpose of this study is to evaluate the long-term safety of paricalcitol injection. Subjects will administer clinical supplies 3 times a week, 40 weeks at dialysis session in dose-titration manner, following 12 weeks of treatment in the dose-response study, M10-309 (NCT00667576).
The primary aim of the study is to assess whether 6-months of vitamin D supplements can decrease PTH compared with placebo treatment in primary hyperparathyroidism.
