| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00000400 ↗ | Alendronate and/or Parathyroid Hormone for Osteoporosis | Completed | National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) | Phase 2 | 1999-08-01 | This study looks at the effects of two medications, alendronate and parathyroid hormone, on bone mass and on bone formation and bone breakdown in women with osteoporosis. We will randomly select postmenopausal women who have osteoporosis to receive laboratory-produced human parathyroid hormone (hPTH), or alendronate, or both for 2.5 years. Study participants will return to the study center periodically to have their bone mass measured and to give blood and urine samples for tests of bone formation and breakdown and for other laboratory tests. Those who complete the study are eligible for one or two 12 month extension studies. |

| NCT00000427 ↗ | Effects of Parathyroid Hormone in Men With Osteoporosis | Completed | National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) | Phase 3 | 1999-09-01 | Alendronate is a drug that blocks or reduces bone loss, while parathyroid hormone (PTH) stimulates the formation of new bone. The purpose of this study is to compare the bone-building effects of PTH alone, alendronate alone, and both PTH and alendronate in men with osteoporosis over a two-and-a-half year period. |

| NCT00000543 ↗ | Oral Calcium in Pregnant Women With Hypertension | Completed | National Heart, Lung, and Blood Institute (NHLBI) | Phase 2 | 1993-08-01 | To determine of providing calcium supplementation to women with pre-existing hypertension reduces the level of blood pressure, requirement for antihypertensive drugs, and incidence of pre-eclampsia. |
| NCT00001277 ↗ | Studies of Elevated Parathyroid Activity | Completed | National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) | 1993-12-15 | Patients whose parathyroid activity is elevated above normal are referred to as having hyperparathyroidism. This study will help researchers better understand the causes of hyperthyroidism and to evaluate and improve methods for diagnosis and treatment. In this study, patients diagnosed with or suspected of having hyperparathyroidism will be selected to participate. In addition, patients with related conditions such as parathyroid tumors, will also be selected. Subjects will be asked to provide blood and urine for testing to confirm their condition. They will then be surgically treated by removal of the parathyroid gland(s) (parathyroidectomy). Subjects with parathyroid tumors will undergo several diagnostic tests to determine the exact location of the tumor as well as the tumor's activity. The tests may include; ultrasounds, nuclear scanning, CT scans, MRI, and specialized blood testing. Sometimes parathyroidectomy leads to hypoparathyroidism. Options for treating the patients after the surgical procedure will also be addressed. Calcium and Vitamin D supplements are typically the mainstay of post parathyroidectomy therapy. Other potential treatments include transplanting the parathyroid gland(s) to other areas of the body. | |
