This is an observational, opportunistic lactation study to be conducted in lactating female participants who are currently receiving therapeutic doses of YORVIPATH as part of their usual care and who have chosen to breastfeed their infant(s). The potential transfer of palopegteriparatide into breast milk will be assessed.

Routine Validation and Reproducibility Testing of Laboratory Assays and Research Techniques Used for Endocrine, Cardiometabolic, and Musculoskeletal Disorder Research (VALD)

The purpose of this research study is to validate (check the accuracy of) laboratory assays, intravenous catheter insertion, and equipment or devices and their reproducibility, which is necessary to perform high quality research on chronic diseases, nutrition, and metabolism (the process by which a substance is handled in the body) at the University of Missouri. As technology changes and uses new testing methods, it is necessary to compare results from old tests, equipment and devices and new tests, equipment, or devices and the reproducibility of these measurements to make sure the results are accurate. Reproducibility means performing the same test more than once to see if the same results can be achieved each time. This study will look at the validation and reproducibility of tests and laboratory assays in participants who are healthy or affected by relevant endocrine, cardiometabolic, and musculoskeletal disorders.

Extension Study to Evaluate the Long-Term Safety and Tolerability of MBX 2109 in Patients With Hypoparathyroidism

The purpose of this study is to evaluate the long-term safety and tolerability of MBX 2109 in patients with hypoparathyroidism who completed the 12-week treatment period in the Phase 2 study, MBX-2H1002.

A Registry for Participants With Chronic Hypoparathyroidism

The main aim of this study is to find out the long-term safety and effectiveness profile of recombinant human parathyroid hormone (1-84) (rhPTH\[1-84\]) treatment in participants with chronic hypoparathyroidism under conditions of routine clinical practice. Participants will be treated according to their clinic's standard practice determined by the treating doctors. Each participant will fill out a study questionnaire during a routine doctor visit.

Translation and Validation of the Hypoparathyroidism Patient Experience Scales (HPES) Questionnaire in Greek

This is a crossectional study that will be conducted at several tertiary centers in Greece. To participate in the study, patients should be ≥18 years of age, fluent in Greek language, diagnosed with chronic HP, on optimal treatment with calcium and active vitamin D metabolites. Chronic HP is defined when continuous therapy with calcium and vitamin D is required for \>12 months. Exclusion criteria will include: 1. Patients inadequately controlled with conventional therapy: 1. corrected serum Ca (cCa) ≤8 mg/dl or cCa ≤8.2 mg/dl with symptoms of hypocalcemia 2. serum P \>5.5 mg/dl 2. Age \>80 years 3. Presence of neoplastic disease 4. Pregnancy 5. Diagnosis of psychiatric disease or cognitive impairment 6. Participants experiencing other comorbidities that may affect QoL 7. Lack of informed consent The study will seek approval from the Ethics in Research Committee of its participating center. All participants will be informed about the objectives of the study and will sign an informed consent. The HPES-Symptom was developed in accordance with the Food and Drug Administration guidance and best research practices for PRO measure development. The methodology used has been previously described. The first step of the translation process requires two forward translations of the English version of the questionnaire. The translations will be done by two translators who are native speakers of the target (Greek) language and can understand the English version. Then a reconciled translation is made based on the two translations - that is, the chief investigator will review the two translations to achieve the best possible version by choosing one of the two translations or by combining them on the basis of their correctness, wording etc. The next step requires translating the reconciled version back into English, again done by two translators who will be native speakers of English or at least will have a very good command of English.

Evaluating the Safety and Efficacy of AMOR-1 as a Treatment for Hypocalcemia Associated With Hypoparathyroidism in Adults

This clinical trial aims to evaluate the efficacy and safety of AMOR-1, consisting of Amorphous Calcium Carbonate (ACC) as the active drug substance, in treating hypocalcemia in adults with hypoparathyroidism.

Parathyroid Allotransplantation in Medically Refractory Hypoparathyroidism

Options for treatment of severe, refractory hypocalcemia are limited for the thousands of patients in the United States who suffer from hypoparathyroidism. Parathyroid allotransplantation is an emerging treatment that provides hope for these individuals. Currently, this therapy has only been successfully provided by a few centers in the world. In the UAB PATH trial, we propose to become one of the few centers worldwide to successfully achieve parathyroid allotransplantation in transplant-naïve patients.

A Phase 2 Trial Investigating the Safety, Tolerability and Efficacy of EXT608 in Adults With Hypoparathyroidism

The goal of this clinical trial is to investigate the safety, tolerability and efficacy of EXT608 in adults with hypoparathyroidism.

Tunisian Clinical Registry on Hypoparathyroidism and Pseudo-hypoparathyroidism

Observational, multicenter, national, cross-sectional study aiming to describe the epidemiological clinical, biological and therapeutic profile of patients suffering from defect in secretion (hypoparathyroidism) or action (pseudo-hypoparathyroidism) of parathyroid hormone.

Establishment of a Registry of Patients With Parathyroid Disease

Establishment of a registry with which to census all patients under the care of the O.U. Endocrinology for parathyroid pathology in order to longitudinally evaluate biochemical, clinical, radiological, medico-nuclear and histological data in future studies.

Institution of an Italian Multicenter Database of Patients Affected by Hypoparathyroidism or Pseudohypoparathyroidism

The goal of this observational study is to create, manage and analyze a multicenter national database of patients affected by hypoparathyroidism or pseudohypoparathyroidism, aimed at collecting and studying anamnestic, diagnostic, genetic, clinical, and therapeutic data in a relatively wide number of patients with these two rare pathologies, in Italy. The study will include 41 specialist clinical centers of endocrinology, pediatric endocrinology, pediatrics, and endocrine surgery, located throughout the Italian territory, and to which patients refer from all the 20 regions of Italy. Data will be collected over time, both in retrospective and prospective manners, during the 10-year duration of the study, starting from the recruiting visit (basal visit) and then during each follow-up visits patients will undergo for the control of disease at the recruiting clinical centers. Collected data will include both the most classic traits of the pathology and the less common ones, with the final goal of refining and deepening medical knowledge in the field of these two clinical conditions affecting parathyroid function and calcium homeostasis, and, thus, to be able to define optimal clinical and therapeutic management of patients, improving their quality of life. The main aspects this observational study aims to assess and clarify are: 1. Evaluation of prevalence and incidence of hypoparathyroidism, globally and in its different etiological forms, and of pseudohypoparathyroidism in Italy. 2. Clinical characterization of different etiological forms of hypoparathyroidism, through both cross-sectional and longitudinal analyses of collected data. 3. Clinical characterization of pseudohypoparathyroidism, through both cross-sectional and longitudinal analyses of collected data. 4. Over time collection of data on bone status and bone fragility in patients with hypoparathyroidism and pseudohypoparathyroidism, to evaluate the prevalence and incidence of fragility fractures in these patients, globally and also based on gender, age, and disease etiology. 5. Over time evaluation of response to pharmacological therapies in patients with hypoparathyroidism and pseudohypoparathyroidism The study will include two independent cohorts of female and male patients of any age, one including patients with chronic hypoparathyroidism of each etiological forms (cohort 1), and one including patients with pseudohypoparathyroidism (cohort 2). The study does not include either any control group/comparison group or healthy volunteers. The study itself does not involve any medical intervention or drug administration. Pharmacological treatments for which data on response to therapy will be collected in the database, are those administered to patients for the control/treatment of hypoparathyroidism or pseudohypoparathyroidism, regardless of their inclusion in this observational study.

Survey on Epidemiology of Hypoparathyroidism in France

Very few data has been published on the epidemiology of hypoparathyroidism worldwide: none exists specifically for France. Hypoparathyroidism could led to complications. Here, the investigators plan to collect data about both epidemiology, medication and complication of hypoparathyroidism in France.
