Clinical trials

The goal of this observational study is to create, manage and analyze a multicenter national database of patients affected by diseases of phosphate metabolism, aimed at collecting and studying anamnestic, diagnostic, genetic, clinical, and therapeutic data in a relatively wide number of patients with these rare inherited metabolic disorders in Italy. The study will include 28 specialist clinical centers of endocrinology, pediatric endocrinology, and pediatrics, 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 each disease and the less common ones, with the final goal of refining and deepening medical knowledge in the field of these rare inherited metabolic disorders, and, thus, to be able to define optimal tailored diagnostic, 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 diseases of phosphate metabolism in Italy, globally and for single different disorders 2. Clinical and biochemical characterization of different diseases of phosphate metabolism (according to single disorders and different genetic base), through both cross-sectional and longitudinal analyses of collected data 3. Evaluation of skeletal health and bone fragility in patients with diseases of phosphate metabolism, globally and based on single phosphate metabolism disorder, gender, and age 4. Self-evaluation of health-related quality of life in patients with a disease of phosphate metabolism 5. Over time evaluation of responses to therapies in patients with diseases of phosphate metabolism. The study will include a single cohort of female and male patients of any age, affected by a disease of phosphate metabolism. 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. Therapies for which response outcomes will be collected in the database, are those commonly employed for the treatment of diseases of phosphate metabolism, regardless of patients' inclusion in this observational study.

The goal of this observational study is to create, manage and analyze a retro-prospective multicenter national database of patients diagnosed with multiple endocrine neoplasia type 1 (MEN1) syndrome (including genetic, clinical and/or familiar diagnosis), aimed at collecting and studying anamnestic, diagnostic, genetic, clinical, and therapeutic data in a relatively high number of patients with this rare inherited endocrine tumor syndrome in Italy. The study will include 33 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 average 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, allowing for an epidemiological evaluation of prevalence and incidence of MEN1 in Italy, collecting detailed clinical history of the disease in enrolled patients, and refining and deepening medical knowledge in the field of this rare inherited endocrine tumor syndrome, and, thus, to be able to define optimal tailored diagnostic, clinical, and therapeutic management of patients, improving their quality of life. Collected data will include both the most classic traits of the pathology and the less common ones. The main aspects this observational study aims to assess and clarify are: 1. Evaluation of prevalence and incidence of MEN1 in Italy. 2. Clinical characterization of MEN1 phenotypes, through both cross-sectional and longitudinal analyses of collected data, and also based on MEN1 mutation types and location. 3. Evaluation of the over time prevalence of bone mass loss, osteopenia, osteoporosis and fragility fractures in patients with MEN1, with and without primary hyperparathyroidism, globally and also based on gender and age. 4. Over time evaluation of responses to surgical and pharmacological therapies in in patients MEN1. 5. Evaluation of dietary habits in MEN1 patients, by filling out a specific questionnaire at the time of the study recruitment. 6. Evaluation of quality of life and accessibility to specialist medical centers and to surgical and pharmacological therapies on the Italian territory by patients affected by MEN1 syndrome, globally and according to the region of residence, by filling out a specific self-evaluation questionnaire at the time of the study recruitment. The study will include a single cohort of female and male patients of any age, diagnosed with MEN1 syndrome (including either genetic, clinical and/or familiar diagnosis). 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. Surgical and pharmacological treatments for which data on response to therapy will be collected in the database, are those commonly employed for the control/treatment of MEN1 tumors and related symptoms, regardless of patients' inclusion in this observational study.

The goal of this observational study is to create, manage and analyze a multicenter national database of patients with parathyroid carcinoma or atypical parathyroid adenoma, aimed at collecting and studying anamnestic, diagnostic, genetic, clinical, histological, and therapeutic data in a relatively wide number of patients in Italy. The study will include 33 specialist clinical centers of endocrinology 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 progression 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 extremely rare parathyroid cancers and be able to define optimal clinical and therapeutic management of patients, improving their quality and life expectancy. The main aspects this observational study aims to assess and clarify are: 1. Evaluation of prevalence and incidence of parathyroid carcinoma and atypical parathyroid adenoma in Italy, both as sporadic disease or in the context of genetic disorders. 2. Clinical, histological, and biochemical characterization of parathyroid carcinoma vs atypical parathyroid adenoma, to assess features and aspects that distinguish these two kinds of tumors and may help in the differential diagnosis. 3. Evaluation of short-term and long-term response to therapies in patients with parathyroid carcinoma and in patients with atypical parathyroid adenoma to assess possible differences between these two types of cancer and, thus, to design tailored clinical and therapeutic managements for patients. 4. Evaluation of short-term and long-term response to therapies in sporadic forms vs genetic forms of parathyroid carcinoma and atypical parathyroid adenoma, to assess possible differences between these two different forms of diseases and, thus, to design tailored clinical and therapeutic managements for patients. The study will include two independent cohorts of female and male patients of any age, one including patients who developed parathyroid carcinoma (cohort 1) and one including patients who developed atypical parathyroid adenoma (cohort 2), both as sporadic cancer or in the context of genetic diseases. 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. Treatments (surgery and/or drugs), for which data on response to therapy will be collected in the database, are those that are conventionally used in patients with parathyroid carcinoma or atypical parathyroid adenoma for treatment of their pathology, regardless of their inclusion in this observational study.

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.
