Filter by:A prospective trial comparing the accuracy of [F-18]-FCH PET/MRI to US and 99mTc-MIBI SPECT/CT for pre-operative parathyroid localization in patients with primary hyperparathyroidism
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.
To evaluate the efficacy of KHK7580 orally administered up to 24 weeks for hypercalcemia in patient with parathyroid carcinoma or primary hyperparathyroidism who are unable to undergo parathyroidectomy or relapse after parathyroidectomy.
This study is conducted to assess the efficacy and safety of SK-1403 in Hemodialysis Patients with Secondary Hyperparathyroidism. In the first treatment period, the efficacy of SK-1403 is assessed after 18 weeks of treatment with SK-1403 individually dose-adjusted . Safety is also assessed during this period. Patients who completed the first treatment period proceed to the second treatment period and receive the treatment with SK-1403 for 34 weeks. Efficacy and safety of SK-1403 are also assessed during this period.
Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").
The aim of this study is to evaluate the prevalence of secondary hyperparathyroidism among patients with diabetic nephropathy.
1. To evaluate achievement ratio of iPTH,Calcium and phosphorus after taking Cinacalcet HCL in hemodialysis subjects with mild, moderate and severe SHPT; 2. To explore the impact of Cinacalcet HCL using on the combined use of drugs; 3. To explore the difference of patients who continued or discontinued Cinacalcet HCL in real-world period from 33rd to 52nd week.
Protocol title: Alterations in functional characteristics of the muscle tissue following surgery for primary hyperparathyroidism. Purpose: To detect any changes in functional characteristics of muscles in patients who undergo surgery for primary hyperparathyroidism compared to patients with primary hyperparathyroidism and conservative treatment, patients undergoing thyroid surgery and healthy subjects. Design: Prospective, multi-center observational study Patient Population: Male or female subjects 18 years of age or older scheduled for parathyroidectomy No. of Subjects: 50 patients undergoing parathyroidectomy, 50 patients undergoing conservative follow up, 50 patients undergoing thyroid surgery due to nontoxic multinodular goiter or solitary nontoxic thyroid adenoma and 50 healthy control subjects, estimated up to 12 months to enroll. Duration of Treatment: During the operation Duration of Follow-up: Follow-up will be performed daily during hospitalization and at 3, 6 and 12 months after the procedure Endpoints: To evaluate the changes in functional characteristics of all the type of muscles which occur after parathyroidectomy for primary hyperparathyroidism.
The only known cure for primary hyperparathyroidism is surgical removal of one or more parathyroid glands. Some patients however, do not fulfill criteria for surgery or do not want to undergo a procedure due to fear of the associated risks. Therefore a medical alternative is warranted. This study aims to evaluate the effects of Denosumab alone, and in combination with Cinacalcet, as a medical treatment for patients suffering from primary hyperparathyroidism, with mild osteoporosis. To the best of our knowledge no previously reported randomized controlled trial has investigated the use of denosumab in primary hyperparathyroidism. 60 patients will be enrolled in three different treatment-groups: 20 receiving both Denosumab and Cinacalcet, 20 Denosumab and placebo and 20 placebo and placebo. Patients included do not meet the criteria for, or have no wish for a surgical procedure. By combining the two drugs, this study could possibly contribute to the discovery of a realistic medical alternative to surgery. It is expected that the therapy will be able to both control s-calcium and s-intact parathyroid hormone (iPTH), and simultaneously enhance bone-structure. The therapy thus has the potential of preventing fractures and possibly other long-term effects of primary hyperparathyroidism such as formation of kidney stones, and coronary calcification. Another objective of this project is to investigate whether the combined therapy can facilitate an actual reset of the Calcium-sensing receptor, and thereby de facto cure the disease.
