A Study to Test Once-Weekly Doses of Odanacatib (MK0822) on Healthy Adult Females (0822-005)(COMPLETED)...
OsteoporosisThis study will assess the safety, tolerability, PK, and PD of a once weekly dose of MK0822 in healthy postmenopausal women.
Trial of Lithium Carbonate for Treatment of Osteoporosis-pseudoglioma Syndrome
Osteoporosis PseudogliomaThis was a pilot study of 10 patients with Osteoporosis-pseudoglioma syndrome (OPPG) from the Old Order Mennonite community and 16 controls, who did not have OPPG. Five of the 10 OPPG patient elected to participate in the Lithium trial and 5 participated only in baseline data (labs, pQCT). The 5 with OPPG who were given lithium for 6 months had both dual energy xray absorptiometry (DXA), peripheral quantitative computerized tomography (pQCT) and lab assessment at baseline and 6 months. Studies in the mouse model of OPPG showed that lithium normalized their bone strength. Controls (n=16) were recruited from the Old Order Mennonite community, to minimize the effects of environmental and lifestyle factors. The controls were not be given lithium. The age range of participants was 4-64 years.
MK-5442 in the Treatment of Osteoporosis in Postmenopausal Women Previously Treated With an Oral...
OsteoporosisPostmenopausal OsteoporosisThis study seeks to demonstrate that additional gain in bone mineral density (BMD) can be achieved by switching to MK-5442 from an oral bisphosphonate in participants who have been receiving oral bisphosphonate therapy for at least 3 years.
A Study Comparing Oral Calcitonin to Nasal Spray Calcitonin in Postmenopausal Osteoporotic Women...
OsteoporosisPostmenopausalThe purpose of this study is to compare the effectiveness and tolerability of two medications, calcitonin nasal spray and a tablet containing calcitonin, in postmenopausal women with osteoporosis. Osteoporosis is the term used to describe a large group of diseases, which are characterized by loss of bone density, which makes the bones weaker. Osteoporosis often occurs in postmenopausal women. Calcitonin is a hormone found in the human body. Together with other substances, it regulates the concentration of calcium in the blood and inhibits the natural resorption of bone. Both medications in this study contain salmon calcitonin (sCT), because this form of calcitonin is more active than human calcitonin when used as a medicine. The calcitonin Nasal Spray used in this study is registered and available to doctors in United States for the treatment of osteoporosis. The medication being tested in this study is an oral tablet form of salmon calcitonin.
A Safety, Tolerability and Pharmacodynamics Study of ACE-011 (ActRIIA-IgG1) in Healthy Postmenopausal...
OsteoporosisThis is a randomized, double-blind, placebo-controlled, multiple-dose, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of ACE-011 in healthy postmenopausal women.
Bisphosphonate Action on the Appendicular Skeleton: Evidence for Differential Effects
Post-menopausal OsteoporosisA study to determine if the three licensed bisphosphonates (alendronate, ibandronate and risedronate):a) affect the peripheral skeleton differently, as assessed by quantitative ultrasound of bone (QUS), peripheral quantitative computed tomography (pQCT) and dual-energy x-ray absorptiometry (DXA)? b) have different effects on bone cells and their activity as assessed by flow cytometry and biochemical markers of bone cell activity? The aim of the study is to compare the effects of three licensed bisphosphonates on bone quantity and quality. There has been no such study before. Most of the measures of bone quantity and quality used in this protocol have not been studied with any of these three agents. The novelty of the study necessitates the establishment of reference ranges and this explains the need for the inclusion of a group of young women.
Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Effect of PTH134 at Increasing Doses in...
Postmenopausal OsteoporosisThis study is designed to investigate the safety and tolerability of PTH134 in healthy subjects and to assess the exposure from PTH134.
A Study to Test the Effect of MK0217A on Vitamin D Inadequacy in Postmenopausal Women With Osteoporosis...
OsteoporosisA study designed to see if the study drug will increase blood levels of vitamin D, bone mineral density (BMD), improve biochemical markers of bone turnover, and reduce the number of falls as compared to women receiving standard care for osteoporosis.
The Effect of Exercise in Postmenopausal Women With Low Bone Density
OsteoporosisOsteopeniaThis clinical trial aims to evaluate the effects of a 12 month gym- and home-based exercise program on bone density and falls risk factors in postmenopausal women with low bone density. It is hypothesised that the exercise program will lead to improvements in bone density and falls risk factors such as balance and muscle strength compared with usual care.
