Filter by:Background: Parathyroid glands in the neck make a hormone that keeps blood calcium levels stable. Sometimes these glands are damaged or removed during neck surgery. This can lead to a condition called postsurgical hypoparathyroidism (PSH). People with PSH have low levels of calcium in their blood. Calcium and vitamin D pills can help them keep their blood calcium levels steady. But this can increase calcium in the urine and result in kidney problems. New treatments for PSH are needed. Objective: To test a drug (encaleret) in people with PSH. Eligibility: People aged 18 or older who have PSH. Design: Participants will be in the study for 6 months. They will have a screening visit and a treatment visit. Screening will take up to 2 days. Participants will have a physical exam. They will have blood and urine tests and tests of their heart function. They will have an ultrasound of their kidneys; they will lie on a table for 15 to 30 minutes while a wand is moved over their back. Treatment will require participants to stay in the clinic for 7 days and 6 nights. They will take the study drug (encaleret) by mouth twice a day for 5 days. They will have a small, flexible tube inserted into a vein; this will remain in place during the visit. Blood samples will be taken through the tube 4 to 9 times each day. Participants urine will be collected. Participants will have follow-up blood tests 1 week after leaving the clinic. They will have 3 follow-up phone calls.
This is a prospective study aiming to establish near-infrared autofluorescence technology and PTH test strip as a standardized process for finding and identifying parathyroid glands in thyroid surgery.
To provide palopegteriparatide (TransCon PTH), an investigational parathyroid hormone (PTH) replacement therapy in an expanded access setting for adult patients with hypoparathyroidism who have previously received PTH-treatment, who meet the eligibility criteria for this protocol as described below and have a clear unmet medical need that cannot be adequately treated by a commercial product or a clinical trial.
The aim of this study is to evaluate, for patients with post-thyroidectomy hypoparathyroidism (HoPT), the severity of their HoPT and to validate clinical scores from a self-administered questionnaire related to this disease (questionnaire which evaluates the severity of clinical symptoms related to HoPT and their impact on quality of life) in order to assess the severity of HoPT and to optimize support.
Long-term conventional treatment of chronic hypoparathyroidism does not fully restore calcium homeostasis leading to increased morbidity, emergency events and reduced subjective health status. To further investigate general morbidity, hypocalcemic events, subjective and daily life performance in patients with chronic hypoparathyroidism a standardized interview as well as blood sampling and examinations such as echocardiography and renal ultrasound are performed.
This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands during total thyroidectomy. It compares risk-benefits and outcomes in patients undergoing total thyroidectomy where NIRAF detection with PTeye for parathyroid identification is either used or not used.
This main aim of this study is to check the level of knowledge and assess attitudes and behaviors of both participants and prescribing physicians regarding the risks and safe use of NATPARA. The survey will be done via internet, telephone, or paper and participants will be able to choose the method that is preferred. No study medicines will be provided to patients in this study.
This study is limited to conduct in China only. The primary objective is to assess the treatment effect of daily TransCon PTH on serum calcium (sCa) levels within the normal range and stopping from therapeutic doses of active vitamin D (calcitriol) or active vitamin D analogue (alfacalcidol) and calcium at 26 weeks of treatment. All subjects will start with 18 mcg of study drug and will be individually and progressively titrated to an optimal dose over a 26-week double blind period, followed by an open label extension period up to 156 weeks. TransCon PTH or placebo will be administered as a subcutaneous injection using a pre-filled injection pen. Neither trial participants nor their doctors will know who has been assigned to each group. After the 26 weeks, participants will continue in the trial as part of a long-term extension study. During the extension, all participants will receive TransCon PTH, with the dose adjusted to their individual needs.
Prospective, observational, single-center study about the use of indocyanine green angiography during total thyroidectomy. The main objective of the study is to identify a quantitative score of parathyroid vascularization as an outcome of angiography that correlates with the absence of postoperative hypoparathyroidism. It is planned to enroll 66 patients.
This study is investigating the safety, tolerability, pharmacodynamics and pharmacokinetics of AZP-3601 following single and repeated administration in both healthy volunteers and patients with chronic hypoparathyroidism (cHP) The protocol includes 3 parts: - Part A: first-in-human single ascending dose (SAD) study in healthy volunteers - Part B: multiple ascending dose (MAD) study with 2 weeks of treatment in healthy volunteers - Part C: open-label MAD study with a total treatment duration of 3 months in patients with cHP.
