Active clinical trials for "Hyperparathyroidism, Secondary"

To evaluate the efficacy and safety of treatment with SK-1403 for 24 weeks in patients with secondary hyperparathyroidism on maintenance hemodialysis.

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.

Chronic kidney disease related mineral and bone disorders (CKD-MBDs) and secondary hyperparathyroidism (SHPT) are observed in most patients with chronic kidney disease on dialysis (CKD-5D). The original use of the calcimimetic cinacalcet in these patients was to reduce the elevated parathyroid hormone (PTH) levels; however, subsequent clinical studies consistently confirmed its beneficial effects on mineral disturbances and bone disease. Although many mechanisms proposed, its specific mechanisms underlying the bone disease is still unclear. Recently, Wnt signaling and their inhibitors were proposed to involve in fine control of osteoclast-to-osteoblast cross-talk. In previous study, investigators explore the changes in Wnt 10b in bone microenvironment after addition of calcimimetic cinacalcet using in vitro osteoclasts. In vitro results were confirmed in 5/6 nephrectomy mice, which were grouped into control, with cinacalcet and without cinacalcet groups. From in-vitro study, investigators found cinacalcet increase mineralization; enhance osteoclast apoptosis, which probably work as osteoclast-osteoblast cross talk for bone formation. Similar results were found in-vivo animal study, and the micro-CT of cinacalcet treated CKD animals revealed a significantly decrease in cortical porosity. On the basis of our in-vitro and animal study, investigators propose that cinacalcet have definitive role on bone turnover marker and bone density changes among SHPT dialysis patients. Methods: Our study includes 50 hyperparathyroid dialysis patients using cinacalcet from 1st Dec 2017 to 31 Oct 2018. Investigators will exclude post-menopausal female subjects. Enzyme-linked immunosorbent assay and Western blot analysis will be done for bone turnover markers (TRACP，Alk-P，S1P，BMP6，Wnt，10B，16，SOST，P1NP，PDGF BB，HGF and CTHRC1, etc.). Bone mineral density will be determined by dual-energy X-ray absorptiometry (DXA). Plasma fibroblast growth factor (FGF-23), Ca 2+ , P 3+ , calcium-phosphorus product and parathyroid hormone will also be measured. Data will be collected and analyzed the differences between baseline measures and 4 weekly and follow up for 6 months after the treatment. Control group that we enrolled 30 hyperparathyroid dialysis patients using traditional therapy active vitamin D without use cinacalcet.

The dialysis patient of chronic kidney disease and parathyroid hormone levels greater than or equal to 800 Pg per ml were divided into two groups by randomized 1:1, one group to receive medication and a control group that did not receive the medication. By group to receive in those taking 25 mg per day to get the default dose and the dose is adjusted according to the levels of calcium and parathyroid hormone. By adjusting the dose of 25 mg every 3 weeks for a period of 12 weeks, the drug is between 25-75 mg dose , with a maximum dose of not more than 100 mg per day (weeks 3, 6 , 9). After a follow-up treatment in weeks 12, 24 and 36 with an blood,ultrasound test parathyroid glands , abdominal x-ray side . To evaluate the changes without the drug .Unless the track during treatment the patients with low blood calcium levels over 8.4 mg per dL . No dose adjustment . regpara while if blood calcium levels less than 7.5 mg per deciliter . Must be stop taking medication for patients in the control group will receive standard treatment . Which consisted of dose vitamin D sterol and parathyroid surgery . Unable to control the level of parathyroid hormone with vitamin D sterol. While participating in the research are not allowed to adjust the amount of vitamin D sterol in the two groups . But the amount of dialysate calcium phosphate binders and can be adjusted as appropriate to healthcare is fine .

To demonstrate the superiority of paricalcitol treatment at early renal post-transplantation (M6) in the control of iPTH (Intact parathyroid hormone) compared to the use of vitamin D nutritional supplements (calcifediol) in patients with renal transplantation.

This study is designed to evaluate safety, pharmacokinetics and pharmacodynamics after single and multiple administration of KHK7580 for secondary hyperparathyroidism in patients receiving hemodialysis

This is an open-label, dose-ranging study of the vitamin D analog DP001 in patients with end-stage renal disease (ESRD). The primary goals of this 4-week Phase 2A study are to identify an appropriate starting dose of DP001 to be used in subsequent studies in this population and for evaluation of pharmacokinetics of DP001 in ESRD patients.

This study is designed to describe the long-term safety and efficacy of etelcalcetide (AMG 416) for the treatment of SHPT in adults with CKD on hemodialysis.

This study is designed in order to investigate the effect of cinacalcet in combination with routine conventional medical management for treatment of secondary hyperparathyroidism (SHPT) and Ca, P control. This study will compare the efficacy of a cinacalcet-based regimen with unrestricted conventional care (vitamin D and phosphate binders) for achieving the stringent National Kidney Foundation Kidney Disease Outcomes Quality Initiative (KDOQI) targets for dialysis patients.

The hypothesis of this study is that subtotal parathyroidectomy using minimally invasive surgery is superior to cinacalcet for the treatment of persistent secondary hyperparathyroidism (HPT) post renal transplant, with minimal morbidity and significantly reduces the cost of treatment post transplant.
