Filter by:Primary objective: Phase I Proof of concept: treatment with smaller doses of elemental calcium from ACC compared to CCS can maintain target serum calcium (corrected for albumin) values (7.0-10.0 mg/dL). Phase II To test the hypothesis that treatment with smaller doses of elemental calcium from ACC compared to CCS can maintain target serum calcium (corrected for albumin) values (7.0-10.0 mg/dL). Secondary objectives: Phase I - ACC dose selection - to confirm the conversion factor of ACC from CCS - To determine the effect of food on ACC absorption Phase II - To test the hypothesis that treatment with smaller doses of elemental calcium from ACC compared to CCS will not cause an increase in hypercalciuria in patients with hypoparathyroidism - To test the hypothesis that smaller doses of elemental calcium from ACC can reduce the side effects related with high calcium consumption. Amorphical has a strong basis to believe that the ACC product is better absorbed compared to the commercially available CCS products and therefore, can maintain desirable target albumin corrected calcium values in serum (CA) with smaller doses of elemental calcium from ACC. As results, the burden of taking high doses of calcium supplementation along with the side effects of the standard therapy (gastrointestinal discomfort and hypercalciuria) will be reduced. Testing serum CA and urine calcium values in subjects with hypoparathyroidism may provide a straightforward method to test this hypothesis. The study is designed to be conducted with extra precaution in order to avoid disturbing the fragile balance between CA levels in serum and calcium levels urine. The crossover design of phase II of the study allows a more accurate and reliable comparison of results attributable to the specific treatment within the same individual. In addition, the subjects will continue consuming all their routine medication throughout the trial. The subjects in the control arm will consume their routine calcium supplement doses thus, will be treated with a standard of care.
The purpose of this study is to identify the number of persons in Denmark with the diagnose hypoparathyroidism, autosomal dominant hypocalcaemia or pseudohypoparathyroidism. Also the investigators want to identify the causes and symptoms of these patients and their prognosis.
This study is designed to evaluate the effect of 6-months of treatment with NPSP558 in reducing requirements for supplemental oral calcium and active vitamin D, while maintaining stable total serum calcium levels in adult subjects with hypoparathyroidism.
This study is a long-term, open-label study using NPSP558 for the treatment of adult patients with Hypoparathyroidism.
Use of PTH (1-84) a recombinant hormone in 25 µg or 50 µg doses for the treatment of adults with hypoparathyroidism. The use of PTH (1-84) should result in a decrease of calcium and vitamin D supplements.
Study hypothesis: supplementary magnesium may influence the blood calcium level in treated hypoparathyroid patients. Patients will be treated with supplementary magnesium (350 mg/day) for 3 weeks. Calcium and other relevant blood parameters will be measured before the treatment, at the end of treatment and 2 weeks after stopping treatment.
In the study will be included patients that have undergone total thyroidectomy and do not display obvious clinical or laboratory hypoparathyroidism. On the third postoperative day and before the patient's exit from the hospital, the patient will undergo an intravenous infusion test with 35ml/m2 dilution of 8.4%(w/v) sodium bicarbonate in two minutes. Three months after the operation, if the study conditions are still met, the patient will undergo an additional parathyroid hormone (PTH) measurement and sodium bicarbonate infusion test and the parathyroid function will be evaluated again.
This study will evaluate the safety, biological activity, and pharmacokinetics of PTH delivered by subcutaneous injection compared with an infusion pump. We anticipate pump delivery of PTH will be more physiologic because it mimics normal parathyroid gland secretion of PTH. We expect that pump delivery will simultaneously normalize blood and urine calcium, phosphorus and magnesium levels with minimal or no fluctuations throughout the day. Pump therapy will require lower PTH doses and should normalize markers of bone turnover. We expect the improved metabolic control during pump therapy will be especially evident in patients with more severe forms of hypoparathyrodism where there is an unmet need for improved therapy.
Use of PTH (1-84) a recombinant hormone in escalating doses for the treatment of adults with hypoparathyroidism. The use of PTH should result in a decrease of calcium and vitamin D supplements.
The aim of the study is to assess whether PTH (1-84) therapy posses advantages compared to conventional treatment in patients with hypoparathyroidism on muscle function, quality of life, calcium homeostasis, bone metabolism, and body composition.
