Active clinical trials for "Osteoporosis"

This study is being conducted to collect information from subjects with osteoporosis regarding their experience using the Forteo B Pen to self-administer teriparatide in the community setting. Information collected during this study will be used to assess the need for changes to the Forteo B-Pen User Manual and patient educational tools. Additionally, the information generated from patients during this trial will be reviewed to assess the acceptability of the Forteo B Pen for commercial launch.

The primary objective of this study is to assess the impact of physician's reinforcement using bone marker data on the subject's compliance (at least 50% drug taken) and persistence on treatment after one year in postmenopausal osteoporotic women.

This study will determine the rapidity of suppression of the bone resorption marker sCTX in post-menopausal women with osteoporosis.Other bone turnover markers will also be evaluated. Patients will be randomised to either monthly Boniva 150mg or placebo, in combination with vitamin D and calcium supplementation. The anticipated time on study treatment is approximately 7 months, and the target sample size is <100 individuals.

The purpose of this study is to compare how well alendronate and raloxifene increase the bone density in women who have osteoporosis and have experienced menopause.

The purpose of this study is to assess bone mineral density in patients switching from an oral bisphosphonate to zoledronic acid, compared to those staying on the oral bisphosphonate.

The purpose of this study is to evaluate the tolerability of two different formulations of blosozumab in women who have reached menopause. This study will last approximately 12 weeks for each participant, not including screening. Screening is required within 28 days prior to starting the study.

Performing resistance training and impact exercise at a moderate to high intensity may help prevent bone loss. However, medications used to treat bone diseases such as osteoporosis reduce the activity of bone cells. The investigators are unsure whether bone cells will still respond to exercise in people on osteoporosis medications. Therefore, investigators have designed a study to compare bone response to moderate-high intensity exercise that involves resistance training and impact exercise versus posture and low intensity balance exercises. Women taking osteoporosis medication will be equally and randomly assigned to one of the exercise groups. There will be 23 participants per group and both exercise programs will be performed over a span of 6 months, twice weekly, for approximately 30-45 minutes per session. Investigators will measure sclerostin, a bone-related protein found in the blood, to see if there are any changes after 3 months of training. Higher levels of sclerostin may result in greater bone breakdown. It is expected that the moderate-high intensity exercise program will decrease sclerostin levels more than low intensity training. Further, changes in sclerostin levels during the 6-month exercise intervention will be explored. The effects of the exercise program on other bone markers in the blood, physical ability, and quality of life will be reported. The willingness of the participants to perform the exercise program and the safety of the exercises provided will also be assessed.

RATIONALE: Zoledronate may prevent bone loss associated with long term androgen deprivation therapy. It is not yet known whether zoledronate combined with calcium is more effective than calcium alone in preventing bone loss. PURPOSE: Randomized phase III trial to compare the effectiveness of zoledronate combined with calcium with that of calcium alone in preventing bone loss in patients with stage III or stage IV prostate cancer who have received long-term androgen deprivation therapy.

Osteoporosis is an important health problem in the rapidly-aging demographic. Fragility fractures are devastating consequences of osteoporosis. The most common treatment approach in osteoporosis is inhibition of bone resorption with drugs like alendronate (ALN). Parathyroid hormone (PTH) stimulates bone formation and is the only anabolic drug available. Dual therapy with ALN and PTH is not as effective as single-drug therapy in preventing fracture. Bone progenitor cells (MSCs) are recruited to sites of bone remodeling when a growth factor called Transforming Growth Factor Beta (TGF-β1) is released from bone. Different osteoporosis medicines may have differing effects on this process. The effects of ALN versus PTH on bone progenitor recruitment in humans are unknown. This is a randomized, clinical trial of ALN, PTH, and calcium and vitamin D in post-menopausal women with low bone mass. Women will be treated for 3 months with ALN or PTH or calcium and vitamin D. Data collected will include bone biopsies for histomorphometry and micro computed tomography (µCT), bone marrow aspirates for molecular studies, peripheral blood to detect circulating bone progenitor cells and dual X-ray absorptiometry. The investigators hypothesize that in humans, PTH will 1) increase bone progenitor number, 2) enhance recruitment of bone progenitor cells to bone resorption sites, and 3) increase bone progenitor number in peripheral circulation. Furthermore, the investigators hypothesize that ALN treatment will have the opposite effect. Understanding the differences in bone progenitor cell activity and recruitment during osteoporosis therapy will provide a mechanistic rationale for effective use of PTH and anti-resorptive drugs in osteoporosis treatment.

The investigators are studying the impact of the interventions of a multidisciplinary team (MDT) - consisting of a Coventry case manager, social worker, and medical director, alongside a Medco specialist pharmacist - on the hospitalization rates of high risk seniors with chronic conditions, compared with a usual care approach. The study will also examine the impact on quality of life, medication adherence, medical costs, hospital readmission rates, and a variety of other important measures. The outcome of COSS may support a means to further enhance and develop a comprehensive care model program by leveraging the partnership between a health plan and a pharmacy benefit manager.
