Active clinical trials for "Osteoporosis, Postmenopausal"

This is a 2year observational study that will recruit patients who have previously completed a randomised, open label, parallel, single centre study (TRIO Study) of three bisphosphonates: alendronate, ibandronate and risedronate. These drugs are the most commonly used group of treatments for postmenopausal osteoporosis in the UK. However, the length of time for which these treatments continue to work after they are stopped has not been fully elucidated. Without this information it is unclear as to how long doctors should treat and whether it would be good practice to give drug 'holidays'. The investigators plan to compare the effects on bone quantity and quality of stopping these licensed bisphosphonates in patients who have taken the medication for a duration of two years. The investigators aim to recruit up to 100 postmenopausal and up to 100 premenopausal (reference range) subjects. Measurements collected at the final visit of the previous study will be used for 'baseline' values for this study. The postmenopausal group will have an initial study visit to secure informed consent, and then further study visits at 24, 48, 72 and 96 weeks after stopping medication. Visit procedures will include: Blood and urine samples for measurements of bone biomarkers Bone Mineral Density of the spine, hip, whole body, forearm Dual-emission X-ray absorptiometry (DXA), and heel dual X-ray and Laser (DXL) Quantitative Ultrasound of Bone (QUS) Vertebral Fracture Assessment (VFA). The premenopausal group will have one study visit, 96 weeks after completing the previous study. Visit procedures will include: Blood and urine samples for measurements of bone biomarkers Bone Mineral Density of the spine and hip (DXA) A subgroup of 50 premenopausal women will also have the following measurements: Bone Mineral Density of the whole body, forearm (DXA), and heel (DXL) Quantitative Ultrasound of Bone (QUS).

This observational cohort study is being conducted to further characterize selected adverse events of interest among a patient population with osteoporosis who are prescribed bazedoxifene, raloxifene, or a bisphosphonate in usual clinical care outside of a randomized clinical trial setting. The study will compare the rates of the selected clinical events among the three treatment groups.

The aim of this study is see the changes in bone mineral density after discontinuation or stop the use of bisphosphonates and make the switch to bazedoxifene).

This observational study assess the safety of intravenous Ibandronate (Bonviva) intermittent administration in patients with postmenopausal osteoporosis and the efficacy of IV Ibandronate (Bonviva treatment through relative lumbar spine and hip bone mineral densitometry form baseline at year 1)

The main purpose of this study is to see what levels of Bone Mineral Density post-menopausal women with breast cancer have, and to see if the level of Bone Mineral Density changes during a women's treatment after her surgery. This trial studies changes in Bone Mineral Density and markers of of bone activity in post-menopausal women receiving treatment for early stage breast cancer.

The miRNA plays an important regulation role in gene expression, and also closely related to bone metabolism. Previous research found that postmenopausal osteoporosis with kidney Yin deficiency syndrome (POP) is associated with CLCF1 gene. This project proposed by bioinformatics prediction CLCF1 targeted regulation of miRNAs, and use the 3 'UTR dual luciferase report system for target validation, aimed at the miRNA levels to explore postmenopausal osteoporosis molecular mechanism with kidney Yin deficiency syndrome.

Osteoporosis is a common disease that makes the bones fragile and easy to break. Osteoporotic fractures are a serious health problem resulting in pain, reduced mobility, increasing degree of dependence and sometimes death. Osteoporosis is currently diagnosed by measuring bone density at the hip/spine through an exam called DXA. Although all post-menopausal women are at higher risk, currently Italian national guidelines do not recommend population-screening programs. This leads to several cases not being identified before a fracture occurs. Since dental panoramic radiographs (OPGs) are common procedures during dental check-ups or before dental treatments, it would be of great value if dentists could use them to identify people with unknown osteoporosis and early refer them to a specialist before they fracture. While several studies support the use of panoramic indices, they have never been tested in an Italian University Hospital setting and in a study adequately powered and controlled for confounding variables. The aim of this study is to assess the feasibility of using dental panoramic indices to screen for post-menopausal osteoporosis.

A randomized, single-blind and parallel group study to compare the pharmacokinetic, safety and immunogenicity of HS-20090-2 60mg#1ml#and Prolia® in healthy adults.

Circulating levels of several myokines will be measured in serum samples obtained from women in various categories of bone density and according to the presence of fracture or not as well as before and after treatment with teriparatide and denosumab

This study is a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Julina for postmenopausal osteoporosis. The objective of this study is to assess safety and efficacy of using Julina in clinical practice. A total 100 patients will be recruited and followed 3 years since starting Julina administration.
