All Clinical Trials for Fosamax

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.

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.

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.

NCT00001720 ↗ Treatment of Childhood Osteoporosis With Alendronate (Fosamax) Completed Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Phase 2 1998-03-01 Bones grow and stay strong through a continuous process of formation (building) and resorption (break down). When more bone is formed than resorbed, the density (level of calcium) in bone increases and the bones become stronger. However, if more bone is resorbed than formed the density of bone decreases and the bones become weak. This condition is called osteoporosis. Osteoporosis is a rare but serious condition in children. Childhood osteoporosis can occur without a known cause (idiopathic juvenile osteoporosis). Children with osteoporosis suffer from pain, inability to stay active, and increased amounts of broken bones, including fractures of the spine. Even mild childhood osteoporosis may have long-term consequences since individuals who achieve a less than normal bone composition (peak bone mass) during the first 20-30 years of life may be at an increased risk for osteoporosis as adults. Alendronate (Fosamax) is a drug that works by stopping bone resorption (break down). It has been used to treat post-menopausal osteoporosis, male osteoporosis and adults with osteoporosis due to long-term steroid therapy. The goal of this study is to determine the effectiveness of alendronate in children with idiopathic juvenile osteoporosis. Researchers believe that children treated with alendronate will improve bone strength and decrease the amount of fractures caused by osteoporosis.
