|---|---|---|---|---|---|---|
| NCT00000412 ↗ | Osteoporosis Prevention After Heart Transplant | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 1997-09-01 | During the first year after a heart transplant, people often rapidly lose bone from their spine and hips. About 35 percent of people who receive heart transplants will suffer broken bones during the first year after transplantation. This study will compare the safety and effectiveness of the drug alendronate (Fosamax) and the active form of vitamin D (calcitriol) in preventing bone loss at the spine and hip after a heart transplant. In this study, people who have had a successful heart transplant will receive either active alendronate and a "dummy pill" instead of calcitriol, or active calcitriol and a dummy pill instead of alendronate for the first year after their transplant, starting within 1 month after transplant surgery. We will measure bone density in the hip and spine at the start of the study and after 6 and 12 months, and will also check for broken bones in the spine. This research should lead to ways of preventing this crippling form of osteoporosis. |

| NCT00427037 ↗ | Cholecalciferol (Vitamin D3) Therapy in Chronic Kidney Disease (CKD) Subjects | Completed | Atlanta VA Medical Center | N/A | 2005-12-01 | This is a 12 week pilot and feasibility study with an enrollment goal of 30 subjects. Half of the subjects will be randomized to vitamin D3 and the other half will receive a placebo. Subjects will be referred from the nutrition or renal clinic at Emory. CKD stage 3 and 4 patients will be eligible for participation if they have been determined to have vitamin D deficiency and are not on treatment with vitamin D or vitamin D analogues. Subjects will sign an informed consent form after reviewing the protocol in detail with the principal investigator. A questionnaire would collect information about dietary vitamin D intake, sunlight exposure, and any symptoms of vitamin D deficiency. The subject will have baseline levels of serum vitamin D (25-hydroxyvitamin D), parathyroid hormone (PTH), serum calcium and phosphate, creatinine and other markers of bone turnover. The questionnaires and the blood draws would be repeated on the 6th and 12th week of the study. Subjects will be given 12 pills of each containing either 50,000 IU vitamin D or placebo and asked to take one pill a week. They would be scheduled to return to the clinic after 6 weeks and blood measurements would be repeated. Subjects will be asked to revisit for their final visit at the 12th week when they would have their last blood draw and assessment. |
| NCT00536991 ↗ | Calcitriol in Combination With Ketoconazole and Therapeutic Hydrocortisone in Treating Patients With Prostate Cancer | Terminated | National Cancer Institute (NCI) | Phase 1/Phase 2 | 2006-10-01 | This phase I/II trial studies the side effects and best dose of calcitriol when given in combination with ketoconazole and therapeutic hydrocortisone and to see how well it works in treating patients with prostate cancer. Calcitriol may help prostate cancer cells become more like normal cells and grow and spread more slowly. Ketoconazole and therapeutic hydrocortisone may help calcitriol work better by making tumor cells more sensitive to the drug. Giving calcitriol together with ketoconazole and therapeutic hydrocortisone may be a better treatment for prostate cancer. |

| NCT00560300 ↗ | Regulation of Bone Formation in Renal Osteodystrophy | Completed | National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) | Phase 2 | 2000-11-01 | To examine the effects of two types of active vitamin D (calcitriol and doxercalciferol) and two phosphate binders (sevelamer and calcium carbonate) on the bone disease and blood tests of children with kidney failure |
