Active clinical trials for "Osteoporosis"

This study is designed to provide information about the bone anabolic properties and absorption profile of Unigene's PTH Analog when administered as oral tablets over a period of 24 weeks to postmenopausal women with osteoporosis.

The primary purpose of participation in this study is to answer whether teriparatide is superior to risedronate in reducing the occurrence of new vertebral fractures during 24 months of therapy.

Current osteoporosis therapies produce a prompt increase in bone mass, followed by only modest or no further subsequent gains. This limitation, known as the "remodeling transient," reflects the "coupling" of bone resorption with formation such that interventions impacting either of these processes lead to compensatory changes of the other. For example, medications which increase bone formation promptly also stimulate bone resorption. Thus, given the need to dramatically increase bone mass in patients with osteoporosis, it is necessary to "uncouple" formation and resorption. The investigators believe this to be possible using currently existing FDA-approved therapeutic agents, by using a novel, sequential approach. This pilot project will obtain preliminary data essential to support future work. In this study, the investigators will begin to explore the use of sequential anabolic treatment with teriparatide followed by antiresorptive therapy with raloxifene. The investigators propose that such sequential treatment will allow opening of the "anabolic window," the brief period of time following initiation of teriparatide therapy in which bone formation exceeds resorption.

This study will evaluate the bioequivalence of alendronate in combination with vitamin D (cholecalciferol) compared to alendronate alone and the bioequivalence of vitamin D in combination with alendronate compared to vitamin D alone.

Osteoporosis is a major health problem in men and women in this country and the incidence of this disease is rising. We think that environmental factors such as nutrition may play a role in the increasing prevalence of osteoporosis. In particular, we think that a diet that is too low in protein may be contributing to bone loss. The primary purpose of this study is to compare the long-term impact of a low protein diet on measures of bone and calcium metabolism.

The purpose of this study is to measure carotid artery IMT at a single visit in a subset of women previously enrolled in the CORE (H3S-MC-GGJY) trial

To test the hypothesis that Teriparatide injections given 20 micrograms/daily subcutaneously, for one month, are able to produce reliable changes in the bone marker in a severe osteoporotic population

The aim of this study is to determine if 3 monthly infusions of zoledronic acid, given over one year, improves the bone mineral density in osteoporotic patients undergoing androgen deprivation therapy for prostate cancer

To compare the subject satisfaction rating in women treated for postmenopausal osteoporosis with Actonel 35mg Once-a-Week for 24 weeks, and receiving feedback information, after 12 weeks of treatment, based on bone resorption marker results using the NTx Point-Of-Care (POC) device, to similar women treated as per regular clinical practice

This is a randomized open label, multi-centre study for Korean women with postmenopausal osteoporosis, evaluating the preference for either the once-monthly dosing of ibandronate or the once-weekly dosing of risedronate. Eligible subjects will be randomised either ibandronate monthly regimen or risedronate weekly regimen. Treatment period consists of 3 month with ibandronate 150mg and additional 12 week with risedronate 35 mg or vice versa. After taking the first interventional medicine for 3 months or 12 weeks completely, a subject changes the treatment arm. There is no washout period.
