Active clinical trials for "Osteoporosis"

Total 25(OH)D is currently used as a biomarker of vitamin D status. However, there is some debate as to whether total 25(OH)D is the best marker to use. It has been suggested that free vitamin D may be better because it may be more biologically available. There are also some uncertainties about how we treat vitamin D deficiency. A single dose is attractive because it is certain that the patient has had the dose and there is no requirement for ongoing compliance, but it is still not clear what the best dose is to give. Also, recent studies have highlighted that high dose vitamin D supplementation may increase the risk of falling in older populations. The investigators believe that studying how free vitamin D responds to different bolus doses is the best way address some of the current research gaps, including what is the best biomarker of vitamin D status, what is the mechanism of vitamin D toxicity and what is a safe bolus dose to treat deficiency. The investigators will study changes in total and free 25(OH)D, and also clinical response, to three different bolus doses of vitamin D (50 000IU, 150 000IU and 500 000IU) in 84 vitamin D deficient postmenopausal women, over a three month period with 5 study visits. A concurrent control group of 28 vitamin D sufficient postmenopausal women will also be recruited. This will allow the investigators to determine how total and free vitamin D change with bolus dosing and whether there is a disproportionate rise in free 25(OH)D with higher doses that may lead to hypercalcemia and falls.

The purpose of this study is to compare the pharmacokinetics (blood levels) of two teriparatide products, PF708 and Forteo, in healthy subjects.

The goal of this study is to determine whether two new, non-X-ray techniques can discriminate between high-energy fractures of normal bone (trauma) and low-energy fractures (fragility) of osteoporotic bone. The current gold-standard for assessing fracture risk areal bone mineral density (aBMD) by dual energy X-ray absorptiometry (DXA) is not particularly effective at identifying individuals who are at risk of suffering a fracture. Yet, there is a growing population of diabetics and elderly individuals prone to fractures. In effect, the age-related and diabetes-related increase in fracture risk is independent of a person's aBMD. These findings stress the urgency in developing diagnostic tools that can improve fracture risk prediction so that patients can be treated with the appropriate anti-fracture therapies.

The purpose of this study is to test whether liraglutide, a drug approved and widely used in the treatment of type 2 diabetes, has an effect on bone mass and bone cell function. Type 2 diabetes may cause multiple complications, and it is well known that patients with type 2 diabetes have a higher risk of fractures. If Liraglutide can be demonstrated to have a positive effect on bone, this may be one among other factors to consider before the decision about specific treatment of type 2 diabetes is made for the individual patient.

A randomized controlled trial to compare for the efficacy and tolerability of denosumab and oral alendronate in the management of glucocorticoid induced osteoporosis

According to the World Health Organization criteria, osteoporosis was defined as a bone mineral density that lies 2.5 standard deviations or more below the average value for young healthy women. Osteoporosis is a major cause of fractures and can lead to serious complications in postmenopausal women. For this reason, approaches to prevent the appearance and progression of osteoporosis are of primary importance. This randomized clinical trial analyzes the effects of two types of physical exercise oriented to prevent osteoporosis in postmenopausal women with pharmacological supplements of Calcium and Vitamin-D.

The study measures change in bone mineral density by the DEXA scan before and two or more years after beginning ten minutes of daily yoga designed to put pressure on the spine, hips and femur.

We investigated the effects of whole body vibration (WBV) and high-impact (HI) exercises in postmenopausal women with low bone mineral density. In summary, WBV exercises are effective in preventing bone loss and WBV and HI exercise programs are effective in decreasing fall risk, increasing health-related quality of life and improving depressive symptoms

This study aims to investigate the effects of SHR-1222 on vascular inflammatory factors in patients with low bone mass.

The purpose of this study is to evaluate the pharmacokinetic characteristics of AD-102 in healthy male subjects
