NCT ID: NCT01598727 Completed - Clinical trials for Primary Hyperparathyroidism

Near Infrared Fluorescent Imaging in Thyroid and Parathyroid Surgery With the Fluobeam(TM) System of Fluoptics

Start date: July 2012
Phase: Phase 1
Study type: Interventional

Hypothesis: Intraoperative use of near infrared fluorescent imaging technology and detection of Methylene Blue fluorescence will improve outcomes following thyroid and parathyroid surgery. Aims: The aims of this phase of the study are to determine the feasibility of using near infrared fluorescent technology in the detection of parathyroid tissue and its differentiation from adjacent soft tissue during surgery on parathyroid glands. Objectives of the phase I study: 1. To familiarise surgical teams with the intraoperative use of the 'Fluobeam(TM)' device (Fluoptics). 2. To understand the patterns (onset, intensity and duration) of fluorescent staining of normal parathyroid glands, thyroid glands and other soft tissue structures encountered during parathyroidectomy. Further research: This will be followed by a phase II study during which fluorescent imaging will be used in conjunction with intraoperative incremental dose of IV methylene blue in both thyroid and parathyroid surgery. Phase II will enable us to develop a protocol for the use of a minimum possible dose of MB for the identification of parathyroid glands. This will then be tested in the pilot phase of a randomized clinical trial.

NCT ID: NCT01571843 Completed - Clinical trials for Osteoporosis, Postmenopausal

Radius Loading in Primary Hyperparathyroidism

Start date: February 2010
Phase: N/A
Study type: Interventional

The purpose of the study is to determine the effect of forearm exercise on forearm bone density in post-menopausal women with or without primary hyperparathyroidism. The investigators hypothesize that forearm exercise will increase forearm bone density in patients with primary hyperparathyroidism more so than in patients without primary hyperparathyroidism.

NCT ID: NCT01530919 Completed - Clinical trials for Primary Hyperparathyroidism

Minimally Invasive Radioguided Parathyroidectomy

MIRP
Start date: September 1998
Phase: N/A
Study type: Observational

The main purpose of this research study is to evaluate the effectiveness of a minimally invasive surgical approach to removing parathyroid gland(s). The researchers are also interested in analyzing abnormal parathyroid tissue for changes in genes and proteins that may contribute to overactive parathyroid gland(s).

NCT ID: NCT01460030 Completed - Clinical trials for Primary Hyperparathyroidism

An Intra-individual Titration Study of KRN1493 for the Treatment of Hypercalcemia in Patients With Parathyroid Carcinoma or Intractable Primary Hyperparathyroidism

Start date: November 2011
Phase: Phase 3
Study type: Interventional

This is an intra-individual titration study of KRN1493 to evaluate the safety and efficacy of KRN1493 for the treatment of hypercalcemia in patients with parathyroid carcinoma or intractable primary hyperparathyroidism (PHPT).

NCT ID: NCT01409798 Completed - Clinical trials for Primary Hyperparathyroidism

The Midwest Head and Neck Cancer Consortium Multi-Institutional Parathyroid Registry

Start date: June 9, 2010
Phase:
Study type: Observational

The purpose of this registry is to create a database that collects clinical data to improve knowledge about primary hyperparathyroidism.

NCT ID: NCT01306656 Completed - Clinical trials for Vitamin D Deficiency

Vitamin D Repletion in Primary Hyperparathyroidism

Start date: October 2011
Phase: Phase 4
Study type: Interventional

This study will look at the effect of 2 treatment regimens that contain vitamin D in a six-month treatment trial of patients with PHPT who are vitamin D deficient. Patients will be assigned randomly to one of 2 regimens, and will be followed with tests of their blood, urine and bones. This study should provide important information on the effect of vitamin D therapy in patients with PHPT. In addition, data from this study will guide physicians as to how best to treat their patients who have PHPT and vitamin D deficiency.

NCT ID: NCT01222026 Completed - Osteoporosis Clinical Trials

Systematic Treatment After Successful Surgical Treatment for Primary Hyperparathyroidism With Strontium Ranelate

Start date: September 2010
Phase: Phase 4
Study type: Interventional

Patients with primary hyperparathyroidism (pHPT) with osteopenia and osteoporosis are treated with strontium ranelate/Ca+Vitamin-D or placebo/Ca+Vitamin D after successful surgical treatment of pHPT. Strontium ranelate/Ca + Vitamin-D helps to regain bone mass in patients with osteopenia or osteoporosis after successful parathyroidectomy for pHPT and results in higher gain of BMD than placebo treated patients.

NCT ID: NCT01057732 Completed - Clinical trials for Primary Hyperparathyroidism

Effects of Parathyroidectomy on Cardiovascular Risk Factors in Primary Hyperparathyroidism

Start date: January 2005
Phase: N/A
Study type: Observational

Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular morbidity. The benefit of surgical treatment in this respect is unclear. This study was performed to evaluate the impact of parathyroidectomy (PTX) on cardiovascular risk profile.

NCT ID: NCT00982722 Completed - Clinical trials for Primary Hyperparathyroidism

Vitamin D Supplementation After Parathyroid Surgery

Start date: April 2008
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00877981 Completed - Clinical trials for Primary Hyperparathyroidism

Open Versus Video-Assisted Minimal-Invasive Parathyroid Surgery

Start date: February 2003
Phase: N/A
Study type: Interventional

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.
