Active clinical trials for "Osteoporosis"

Randomized, multicenter, double-blind, double-dummy, active-controlled, parallel-design study in approximately 201 postmenopausal women. A subset of subjects (approximately 102) will also participate in a pharmacokinetic (PK) component of the study. Each subject will be randomized to 1 of 3 treatment regimens for 3 months.

The purpose of this study is to determine the duration of the treatment with alendronate in postmenopausal women with osteoporosis.

This is a multi-center, randomized, open-label, parallel group, study being conducted in the United States and in Europe in postmenopausal women. Approximately 800 subjects will be randomized across about 65 sites in a 1:1 ratio to either denosumab 60mg SC Q6M, or ibandronate 150mg PO QM.

The purpose of this study is to see how well alendronate and calcium as compared to calcium alone increase bone density in postmenopausal women with osteoporosis

To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis

Compare subject satisfaction of once a week dosing of 35 mg Risedronate to once daily dosing of 5 mg Risedronate in postmenopausal osteoporotic women. Secondary objectives are to measure compliance (50 % drug taken), and persistence.

This single arm study will assess participant preference for monthly Bonviva, versus daily or weekly alendronate or risedronate, in the treatment of postmenopausal osteoporosis. Participants currently on a daily or weekly regimen of bisphosphonate therapy (alendronate or risedronate) will answer a questionnaire to identify participants who may benefit from a monthly Bonviva regimen. Eligible participants will then discontinue their present bisphosphonate treatment, and switch to monthly Bonviva 150mg per oral (po). At the beginning and end of Bonviva treatment, all participants will complete an Osteoporosis Patient Satisfaction Questionnaire. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

This 2 arm crossover study will evaluate patient reported preference for either once monthly Boniva (150mg p.o.) or once weekly risedronate (35mg p.o.). Patients with post-menopausal osteoporosis will be randomized to receive Boniva for 3 calendar months or risedronate for 12 weeks; they will then cross over to receive the alternative treatment for a further 12 weeks/3 months. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Decreased bone strength is a serious medical problem present in many women with Anorexia Nervosa, or disordered eating. Women with weaker bones are more likely to suffer broken bones than women with normal bone strength. We are investigating whether a hormone that is naturally produced by the human body, called growth hormone, can help strengthen the bones of women with this type of disordered eating.

The purpose of this study is to determine how treatment with raloxifene compares to treatment with alendronate in postmenopausal women with osteoporosis on the chance of experiencing fractures
