Filter by:This is a prospective cohort study aimed to evaluate change of cardiovascular calcification after parathyroidectomy in patients with end-stage renal disease on dialysis compared with control group on conservative treatment.
The purpose of this study is to evaluate the efficacy and the safety of KHK7580 orally administered once daily for 52 weeks compared to cinacalcet hydrochloride as an active control in subjects with secondary hyperparathyroidism receiving hemodialysis in China, Korea, Hong Kong and Taiwan.
To evaluate the efficacy and safety of treatment with SK-1403 for 24 weeks in patients with secondary hyperparathyroidism on maintenance hemodialysis.
Pharmacokinetics and Safety Study of CTAP101 Capsules in Japanese and non-Japanese Healthy Subjects
To evaluate the safety and efficacy of treatment with SK-1403 for 52 weeks in patients with secondary hyperparathyroidism on maintenance hemodialysis.
Kidney disease patients have a variety of bone disorders that result in bone loss and fractures. The mechanisms of these bone disorders are not clear but may be related to abnormal modification of a bone protein known as collagen. Therefore, the investigators are conducting this research study to identify underlying mechanisms that are responsible for the disruption of bone collagen and determining whether the abnormal bone collagen impairs bone strength. The investigators intend to identify these mechanisms through studying relationships between kidney disease and bone strength via bone imaging, bone biopsy and non-invasive measures from blood and skin.
An Open-Label, Repeated-Dose Safety, Efficacy, Pharmacokinetic and Pharmacodynamic Study of Oral CTAP101 Capsules, Immediate- Release (IR) Calcifediol, High-Dose Cholecalciferol, and Paricalcitol Plus Low-Dose Cholecalciferol in Patients with Secondary Hyperparathyroidism, Stage 3 or 4 Chronic Kidney Disease and Vitamin D Insufficiency
The main study aim is to quantify the agreement between the analytical results provided by two third generation and two second generation Parathyroid hormone (PTH) assays. The primary comparison will be performed between the second-generation PTH assay"Intact PTH assay" from Siemens Healthcare Diagnostics Inc. and the third-generation PTH assay "biointact (1-84)" from Roche Diagnostics in terms of a Bland-Altman analysis. Several studies have evaluated the correlation between various PTH assays at a single time-point, but no previous study has tested the hypothesis that longitudinal changes in PTH levels, which are important for making treatment decisions, can be monitored by several PTH assays alike. To this aim, the key secondary objective is to analyze the longitudinal variance in PTH over the course of 1 year, using each of two assays of the second and third generations, respectively. Other secondary objectives include determining changes in serum phosphate, serum calcium, fibroblast growth factor 23 (FGF23), with respect to treatment decisions. For clinical applicability of the results to be obtained here, an important goal of the present study will be not to influence treatment decisions, which will remain independent of the study investigators, at the full responsibility of the hemodialysis physicians. At every quarterly blood draw over the course of one year, the investigators will freeze the serum from 100 patients, and at the end of 4 quarters the investigators will analyze PTH-levels using the following assays: Intact Parathyroid Hormone (Advia Centaur, Siemens Healthcare), PTH-Intact (Cobas, Roche), PTH (1-84) - The agreement between the PTH assays will be analyzed at baseline, as well as at the subsequent quarterly evaluation time-points by Bland-Altman analysis and complemented by Passing-Bablok regression. The longitudinal changes in PTH will be displayed graphically and analyzed by estimating the within-patient variance across time, the between patient variance at each time-point as well as effects on the mean log-PTH level due to course of disease and therapeutic interventions from a linear mixed model.
The primary objective is to demonstrate that treatment with etelcalcetide (AMG 416) is not inferior to treatment with cinacalcet for lowering serum intact parathyroid hormone (PTH) levels by > 30% from baseline among participants with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT) who require management with hemodialysis.
This was a multiple-dose, double-blind, randomized, placebo-controlled study. Chinese subjects residing in Mainland China with chronic kidney disease (CKD) receiving hemodialysis were randomized in a 3:1 ratio to receive 5 mg intravenous (IV) of etelcalcetide or placebo 3 times a week (TIW) for approximately 4 weeks, with a subsequent follow up period of approximately 4 weeks. Doses were given at the end of each scheduled hemodialysis session on study days 1 through day 27 and subject participation was complete after day 55 end-of-study (EOS) procedures were performed. Doses were administered TIW for 4 weeks, for a total of 12 doses.
