Filter by:A randomised double blind clinical trial, accepted by the Medical Products Agency and registered in the European Clinical Trials Database. Aims to evaluate the prevalence of vitamin D deficiency in a pHPT population in relation to gender and age, the correlation between vitamin D status, pre- and postoperative parathyroid hormone level and bone density and the correlation between vitamin D status, metabolic, cardiovascular risk factors and QoL aspects before and after parathyroid adenomectomy.
This study is designed to demonstrate the efficacy and to assess the safety of cinacalcet for the reduction of hypercalcemia in patients with primary hyperparathyroidism for whom parathyroidectomy is indicated on the basis of an elevated corrected total serum calcium, but who are unable to undergo parathyroidectomy.
This multicenter, open-label, single-arm, extension study was designed to evaluate long-term tolerability, safety, and efficacy of cinacalcet. Subjects were enrolled immediately after they completed the parent study, 990120. All subjects began treatment with 30 mg cinacalcet twice daily (BID), with dose adjustments made per protocol-specified guidelines. The study consisted of 2 consecutive phases that occurred in the following order: a dose-titration phase lasting 12 weeks and a maintenance phase lasting approximately 4½ years.
This randomized, placebo-controlled study in patients with primary HPT was designed to evaluate the efficacy, safety, pharmacokinetics, and health-related quality of life (HRQOL) of AMG 073 when administered 2 times a day (BID). The study consisted of 3 phases: a 12-week dose-titration phase, a 12-week maintenance phase, and a 28-week follow-up phase.
This is a multicentre, descriptive observational study of adult patients with primary HPT receiving cinacalcet in clinical practice in a number of countries in Europe. Patients will be enrolled within 1 month of initiating cinacalcet treatment, and data will be collected prospectively for up to 1 year from initiation. Data will continue to be collected from patients discontinuing cinacalcet before the end of this period.
The aim of the present study was to compare open minimal-invasive parathyroid surgery with video-assisted parathyroidectomy in primary hyperparathyroidism (PHPT) patients with a positive sestamibi scan in a multicentre randomized trial in order to evaluate if videoassisted surgery gave less postoperative pain and if there was a difference in operating time.
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.
The goal of this clinical research study is to learn how the standard practice of giving Vitamin D supplements to patients with a Vitamin D deficiency may affect the size of the parathyroid glands in patients with PHPT and a Vitamin D deficiency.
The present study is a randomized, controlled trial that investigates the effects of parathyroidectomy or medical observation in mild asymptomatic pHPT on morbidity and quality of life (QoL).
This is a research study to investigate cardiovascular health in people with mild hyperparathyroidism. Previous research has suggested that severe hyperparathyroidism may be associated with abnormalities in the heart and blood vessels. It is unclear whether mild hyperparathyroidism affects cardiovascular health. This study involves the investigation of the heart and blood vessels of people with mild hyperparathyroidism. Various non-invasive laboratory and radiological test to assess cardiovascular and bone health will be done at set intervals over the course of 2 years. It is our hypothesis that patients with primary hyperparathyroidism will have subtle abnormalities in their cardiovascular system. Using state-of-the art techniques that are sufficiently sensitive to detect these subtle abnormalities, we will define cardiovascular features of this disease that have, up to now, eluded clear definition. We expect taht the extent of these findings will be related to the severity of the underlying primary hyperparathyroidism. We further hypothesize that cardiovascular manifestations may regress with successful cure of the hyperparathyroid state.
