Filter by:Study consists of an eight day inpatient visit on the General Clinical Research Center. The investigators' specific aims are to: 1. To define the maximum safe dose of a seven day continuous administration of parathyroid hormone [PTH(1-34)] in healthy human volunteers. 2. To estimate the effect of a seven day continuous administration of PTH in escalating doses on vitamin D metabolism, markers of bone turnover and fractional excretion of urine.
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.
The purpose of this study is to determine whether zoledronic acid given intravenously every 6 months can prevent reduction in bone mineral density in women with early stage breast cancer receiving adjuvant therapy with the aromatase inhibitor drug letrozole, after having received adjuvant tamoxifen.
To determine and compare the effects of Hormone replacement therapy (HRT), etidronate, HRT plus etidronate and no treatment over 5 years in the prevention and treatment of glucocorticoid-induced osteoporosis and fractures in post-menopausal women with asthma.
The efficacy of risedronate in prevention of bone loss in patients receiving high dose corticosteroid treatment
This study is a double-blind placebo-controlled trial evaluating the efficacy of raloxifene in the prevention of bone mineral density loss in patients receiving long term corticosteroids.
RATIONALE: Diagnostic procedures, such as bone mineral density testing and x-ray, help measure bone loss in women receiving treatment for breast cancer. The test results may help doctors plan better treatment. PURPOSE: This phase III trial is studying bone density and bone loss in postmenopausal women with breast cancer receiving treatment in clinical trial IBCSG-1-98.
A study was designed with two specific aims: (1) to assess the effect of soy bread, compared with wheat bread, on markers of bone metabolism and cardiovascular health, and (2) to evaluate whether soy bread consumption affects the metabolism of phytoestrogens. To answer Aim 1, a double-blind randomized crossover trial was conducted. Individuals with an ability to metabolize a specific isoflavone, daidzein, consumed 3 slices of bread (either soy or wheat) daily over a 12-week period. After a 4-week wash-out period, subjects consumed 3 slices/day of the other type of bread. Markers of bone metabolism and cardiovascular health were evaluated before and after each time period. To answer Aim 2, individuals who did not metabolize daidzein at baseline entered a double-blind randomized trial of soy bread with or without fructooligosaccharide (a type of dietary fiber) over an 8-week period. Subjects were evaluated regarding their ability to metabolize daidzein to equol.
This methodology trial will be conducted in patients with osteoporosis and will measure the changes in bone quality parameters, micro- and macroarchitecture, bone biomarkers and bone density following therapy with the approved drug, Forteo.
The objective is to show superior efficacy of PTH (1-84) over risedronate in treating osteoporotic women for 12 months after having previously been treated with PTH (1-84) for 12 months followed by 12 months treatment with risedronate.
