Active clinical trials for "Osteoporosis"

This study will compare the efficacy and safety of different treatment regimens of oral Bonviva tablets in women with post-menopausal osteoporosis. Patients will also receive daily supplementation with vitamin D and calcium. The anticipated time of study treatment is 2+ years, and the target sample size is 500+ individuals.

Osteoporosis is a condition in which the amount of bone is reduced, the bones are weak, and there is an increased risk for fractures. Glucocorticoids (such as prednisone) are prescribed to treat a large number of conditions such as arthritis and asthma. When taken for several months or longer, glucocorticoids can cause bone loss and lead to a form of osteoporosis called "glucocorticoid-induced osteoporosis." This study compared the effects of teriparatide, the study drug, with alendronate, an approved drug for treating glucocorticoid-induced osteoporosis.

The purpose of this study is to evaluate the efficacy and safety of an investigational drug in postmenopausal women with osteoporosis. The primary hypothesis of this study is that in postmenopausal women with osteoporosis, oral monthly ibandronate, at doses of 100 mg and 150 mg, does not achieve persistence in reduction of bone resorption throughout the monthly dosing interval, as demonstrated by a larger change in the serum carboxyterminal crosslinked telopeptide of Type I collagen (CTX-I) log-transformed fraction from baseline four weeks post dose compared to one week post dose, during the third month of treatment, in the participants taking ibandronate than in the participants taking placebo.

Daily parathyroid hormone (PTH) is approved by the FDA for the treatment of osteoporosis. This study will evaluate the safety and effectiveness of PTH when given once a week.

This extension study is designed to assess the long term safety and efficacy of zoledronic acid in postmenopausal women with osteoporosis who have participated in the CZOL446H2301 (NCT00049829): HORIZON Pivotal Fracture Trial. This extension study began after the 3-year core study ended. Baseline is the same as Year 3.

To determine how prior therapy with alendronate or risedronate in postmenopausal women with osteoporosis influences the clinical effectiveness of teriparatide; The primary objective of the study is to compare the teriparatide (human, recombinant PTH[1-34])-associated change from baseline in a marker of bone formation, N-terminal propeptide of type I collagen (P1NP), between subjects previously treated with risedronate and those previously treated with alendronate.

The purpose of this randomized, double-blind, placebo-controlled study is to estimate the effect of oral ibandronate sodium (Boniva) taken once monthly versus placebo on bone quality and strength at the proximal femur at one year.

The primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.

The purpose of this study is to determine if a new test for osteoporosis can be useful in monitoring treatment. We are studying a new method for examining the quality of bone by an experimental method of computerized analysis of radiographic images (x-ray pictures) of the heel.

To establish the optimal dose of lasofoxifene that is fully effective in increasing the BMD in postmenopausal Asian women.
