Active clinical trials for "Osteoporosis, Postmenopausal"

A 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.

This study is designed to investigate the safety and tolerability of PTH134 in healthy subjects and to assess the exposure from PTH134.

This study will evaluate the effects of zoledronic acid 5 mg infusion on BMD and biochemical markers of bone in post-menopausal osteoporotic patients aged between 50-65.

The purpose of this trial is to study the efficacy of a 35 mg delayed release weekly dosing regimen as compared to the standard daily dosing regimen of risedronate 5 mg daily.

To compare in postmenopausal women with established osteoporosis the effect of treatment with teriparatide 20 micrograms/day subcutaneous with the effect of salmon calcitonin 100 IU/day subcutaneous on change in lumbar spine BMD.

A 2-year, Multicenter, Open-label, Phase IIIb Extension Study to Assess Bone Mineral Density and Bone Turnover Response to 5 mg Daily Risedronate Treatment in Women with Postmenopausal Osteoporosis Who Sequentially Completed Clinical Studies RVE009093, RVE1996077, RVE1998080, and RVE2001079 (NCT01249261)

To see if using teriparatide for 12 months will increase Bone Mineral Density at the lumbar spine in postmenopausal women with osteoporosis

The purpose of this study is to evaluate treatment adherence to different regimens of ibandronate in postmenopausal women with osteoporosis or osteopenia who are intolerant to daily or weekly alendronate or risedronate therapy due to gastrointestinal (GI) side effects. The anticipated time on study treatment is 12 months, and the target sample size is 517 individuals.

This study will evaluate whether an early positive response to once-monthly oral ibandronate in treatment-naive participants with postmenopausal osteoporosis is predictive of efficacy later in treatment. The anticipated time on study treatment is 6 months, and the target sample size is 360 individuals.

This study will compare the effectiveness of denosumab treatment every 6 months with once yearly zoledronic acid treatment on bone mineral density (BMD) at various skeletal sites.
