Active clinical trials for "Hyperparathyroidism, Secondary"

This study is designed to assess the efficacy and safety of etelcalcetide compared with placebo in the treatment of SHPT in patients with chronic kidney disease (CKD) receiving hemodialysis.

The purpose of this study is to evaluate the effect of thrice weekly intravenous (IV) administration of etelcalcetide in the treatment of secondary hyperparathyroidism (SHPT) in hemodialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD).

This is a pilot, prospective randomized controlled study with the primary objective to evaluate and compare medical treatment of severe SHPT, namely oral cinacalcet versus surgical treatment, that is, parathyroidectomy with forearm autografting, on the progression of coronary artery and valvular calcification and left ventricular mass index in endstage renal disease patients receiving peritoneal dialysis over 12 months. The change in arterial stiffening, left ventricular volume, aortic valve calcium score and bone mineral density, nutritional status and biochemical parameters, quality of life measures will be evaluated as secondary objectives of this study.

This is an open label, single center, randomized, active comparator controlled study, comparing the effects of vitamin D replacement using oral ergocalciferol versus paricalcitol on parathyroid hormone (PTH) levels in patients with stage 3 and 4 CKD and vitamin D deficiency or insufficiency. The purpose of this study is to determine which of these two approaches is more successful.

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

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.

There are still no established protocols for maintenance therapy with intravenous or oral vitamin D preparations after the iPTH target has been achieved. Therefore, the present study compared the efficacy of two maintenance therapy protocols, i.e., oral administration of alfacalcidol (an oral vitamin D preparation) at a dose of 1.0 ug/day (higher-dose group) or at a dose of 0.25 ug/day (lower-dose group), in patients with secondary hyperparathyroidism who responded to initial maxacalcitol therapy, resulting in the control of iPTH to < 150 pg/mL.

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).

This study is being done to find out whether patients who receive a kidney transplant can benefit from taking the medication paricalcitol (trade name Zemplar®) as compared to kidney transplant recipients not taking this medication. The main possible benefits being studied are: Lower risk for overactive parathyroid glands after kidney transplantation. Lower risk of low bone density in the spine and hip after kidney transplantation. By dividing patients in the study into a group receiving Zemplar® and a group not receiving Zemplar®, it will be possible to understand the good and bad effects of Zemplar® during the first year after a kidney transplant.
