Active clinical trials for "Osteoporosis"

The purpose of this study is to test the hypothesis that treatment with odanacatib will result in increased bone mineral density (BMD) compared to treatment with placebo. This study will also evaluate the safety and efficacy of odanacatib for male osteoporosis participants.

Multicentered, randomized study of safety and efficacy of whole-body vibration (WBV) as add on to standard pharmacological treatment of osteoporosis (alendronate 70 mg/ week or raloxifene 60 mg/day) in post-menopausal women. After informed consent of the patients has been obtained, each patient's potential eligibility will be assessed during a "Screening Visit". Eligible subjects will be stratified into two groups: those that are on treatment with alendronate and those that are on treatment with raloxifene. Subsequently, at baseline, the patients in each group are randomised to receive either WBV or no WBV during the first segment of the study. Baseline evaluation of biomarkers of bone remodelling, fall risk and back pain will be performed before starting the first segment. Patients will return for efficacy and safety evaluations at week 3 and week 6. At 6 weeks after baseline the second segment of the study starts: patients that were on WBV during segment I will be observed for another 6 weeks without WBV, whereas the patients that did not receive WBV during segment I will now be treated with WBV for 6 weeks in segment II. All patients will return for additional visits at week 9 and 12 for safety and efficacy evaluation.

Study is designed to evaluate the efficacy of oral fosamax in prevention on osteoporosis in acute spinal cord injury. Efficacy will be measured by a duel energy X-Ray absorptiometry (DEXA) scan every 6 months. Patients will complete 3 visits, screening, 6 months, 12 months and be required to take oral fosamax versus placebo weekly.

Hip fractures mostly occur in elderly people with low bone strength. Bone strength is determined by bone mineral density (BMD), bone turnover, microarchitectural and geometrical properties of the bone. Dual energy x-ray absorptiometry (DXA) is the standard technique to measure BMD. However, BMD just provides information regarding the quantity of mineral in bone, which is only one component of bone strength. To date there is no reliable method to assess bone strength in vivo. Therefore, a method to assess bone strength beyond BMD would provide additional information regarding the patients' risk of bone related fixation failure after fracture fixation. DensiProbe is a new diagnostic device that was developed for intra-operative assessment of mechanical stability of the bone in the proximal femur. It consists of a drill bit like tool and an electronic system to measure the peak torque to break-away of trabecular bone in the femoral head of patients undergoing DHS surgical treatment. In a cadaver study comparing bone mineral density measured by quantitative computed tomography with bone strength measured by DensiProbe a high correlation between these two parameters could be shown. In a clinical pilot study a significant correlation between DensiProbe measurements and BMD measured by DXA at the femoral neck in patients with hip fractures could be shown. However, no perfect correlation was expected because DensiProbe measures bone strength, which is only partly caused by BMD. Bone related fixation failure, such as secondary loss of reduction, is influenced by bone strength, bone mineral density, fracture type, fracture reduction and primary positioning of the implant. The predictive value of DensiProbe measurements for secondary loss of reduction needs to be investigated. If DensiProbe turned out to be an effective screening tool for patients with low bone strength that are on higher risk of the aforementioned complications these patients may in future benefit from alternative treatment methods (e.g. augmentation techniques) in order to reduce bone related fixation failure. The primary aim of the present study is to investigate if bone strength measured by DensiProbeTM Hip (DensiProbe) is an independent factor to predict secondary loss of reduction (screw migration of 5 mm or more and / or telescoping of 10 mm or more) in patients with hip fractures after fracture fixation with DHS.

This study will evaluate the safety and treatment effect of 50 mg odanacatib (MK-0822) with Vitamin D versus placebo with Vitamin D in postmenopausal women with low bone density. The primary efficacy hypothesis is that odanacatib will increase aBMD at the lumbar spine compared to placebo at 12 months.

This is a multi-center, randomized, double-blind, double-dummy study designed to compare the effects of risedronate, raloxifene, and placebo on BMD, bone turnover markers, and other markers of anabolic activity in postmenopausal women who previously received HRT.

Background: Up to 30% of children and adolescents with Crohn's disease have decreased bone strength, or decrease bone density, called osteopenia. Bisphosphonates are a group of drugs that have been well studied and found to be effective in the treatment of osteopenia in menopausal women. Zoledronate is a very potent third generation bisphosphonate, that is safe and easy to administer, and has been found effective in the treatment of menopausal women with osteopenia. Hypothesis: The investigators hypothesize that zoledronate can improve bone density in children and adolescents with Crohn's disease with osteopenia.

The purpose of this research study is to evaluate the safety and effectiveness of this investigational drug for the treatment of menopausal symptoms while protecting the endometrium (uterine lining) and preventing postmenopausal osteoporosis. Subject participation will last approximately 14.5 months.

The purpose of this study is to determine whether percutaneous vertebroplasty is able to improve long-term quality of life in patients with pain secondary to osteoporotic vertebral fractures, compared to conventional medical treatment.

The primary purpose of this study is to help answer the following research questions: How teriparatide given using a skin patch (transferred through the skin using the ViaDerm Teriparatide System) compares to teriparatide injected under the skin with a needle (pen injector) affects your bone density (how solid or porous your bones are). The safety of the teriparatide skin patch and any side effects that might be associated with it.
