NCT02655055
A longitudinal, randomized, controlled, single-center Phase IV clinical trial will be performed to assess changes in bone mineral density (BMD) among voluntary apheresis blood donors. The primary outcome measure will be clinically significant decline in BMD at the lumbar spine assessed by dual-energy x-ray absorptiometry (DXA).
NCT07187518
Osteoporosis is a widespread medical condition among older people. It causes the bones to weaken and become more likely to break. Osteoporosis and bone fracture risk are currently evaluated by looking at clinical risk factors and measuring bone mineral density (BMD). The lower the BMD is, the higher the risk of osteoporotic fractures in the future. An X-ray device called DXA is the main tool used to diagnose osteoporosis and fracture risk clinically. DXA measures two-dimensional BMD in the hip and spine. However, DXA devices are often not readily available at the point of care. The POROUS ultrasound device offers a different approach by measuring various properties of the outer layer of the bone in the lower leg. It has several advantages over DXA: (1) higher and three-dimensional image resolution; (2) the ability to measure bone properties without radiation; (3) portability, it is a mobile medical device; 4) lower operational costs. For this clinical study, we will recruit men and women between the ages of 21 and 55. Most of these study participants will not have evident clinical risks for osteoporosis. The goal for including this age group is to estimate the range of BMD values for younger people before BMD declines with age. In a separate clinical study, we are recruiting older participants. The study is anticipated to last one year. Our major research questions are: * Can the POROUS ultrasound device estimate BMD? * How does its performance compare to DXA? * What is the safety of the new device? The participants will: * answer questions about their medical history. * be measured for height and weight. * be examined with the two devices, DXA and POROUS.
NCT01144377
The primary objectives of this study include evaluating the dose response of LY2541546 using bone mineral density (BMD) change from baseline as compared to placebo and evaluating the overall safety and tolerability of LY2541546 following multiple subcutaneous administrations in postmenopausal (PMP) women with low BMD. Following the last dose of study drug, participants will be able to participate in a 12 month extension to collect additional safety and efficacy data (no further treatment will be administered during this extension).
NCT03292146
This protocol is a randomized, double-blind, placebo-controlled clinical trial which aims to investigate the effect of denosumab on BMD in women with anorexia nervosa. The investigators hypothesize that 12 months of denosumab administration will result in an increase in bone mineral density, decrease in markers of bone resorption and improvement in bone microarchitecture in osteopenic women with anorexia nervosa compared with placebo. An optional extension study will offer subjects 12-month administration of open-label alendronate (an oral bisphosphonate) after the initial 12 month administration of denosumab or placebo. We hypothesize that 12 months of denosumab followed by 12 months of open-label alendronate will result in a greater increase in BMD compared to 12 months of placebo followed by 12 months of open-label alendronate. Within the group of women who receive sequential therapy with 12 months of denosumab followed by 12 months of alendronate, we hypothesize that BMD will be maintained between 12 and 24 months while on alendronate.
NCT00176579
RATIONALE: Measuring bone mineral density may help doctors predict whether prostate cancer will come back. It may also help the study of prostate cancer in the future. PURPOSE: This clinical trial is studying whether bone mineral density affects cancer recurrence in patients with early stage prostate cancer.
NCT00587925
Bone Mineral Density (BMD) as measured by X-ray shows the amount of calcium in the bone. Low BMD may reflect osteoporosis, a condition where there is an increased risk of fracture. Women who have gone through menopause have a higher risk of getting osteoporosis because they lose calcium from their bones much faster than younger women. Women with breast cancer may have an additional risk for getting osteoporosis because of the effects of their treatment with chemotherapy. The purpose of this study is to see what levels of BMD post-menopausal women with breast cancer have, and to see if the level of BMD changes during a women's treatment after her surgery. This trial studies changes in BMD and markers of bone activity in women receiving treatment for early stage breast cancer.

NCT00277251
This trial will test the hypothesis that among 20 children and adolescents from Children's Hospital, Boston with Crohn's disease, ulcerative colitis, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus, mixed connective tissue disease and vasculitis, treatment of glucocorticoid-associated osteopenia and osteoporosis with 18 months of alendronate (FOSAMAX®, Merck \& Co., Inc.) will result in greater improvement in the mean change of individual AP spine bone mineral density (BMD) (gm/cm2) determined by dual energy X-ray absorptiometry (DXA) than treatment with 18 months of standard of care therapy.
NCT05387200
This study aims to prove non-inferiority of the efficacy of Masibone S (alendronate sodium trihydrate 70mg, oral solution) on the treatment of postmenopausal osteoporosis compared to the efficacy of Fosamax (alendronate sodium 70mg, oral tablet). The effect of Masibone S and Fosamax on bone mineral density in postmenopausal women with osteoporosis will be compared and analyzed. This study included a total 170 patients (85 per subgroup) for multi-center, randomized, open-label, parallel clinical trial. The drugs will be maintained for a total of 48 weeks. The primary endpoint is the difference of bone mineral density change at lumbar spine measured by DEXA between two groups.
NCT00688246
RATIONALE: Learning about the effect of exemestane on bone mineral density in postmenopausal women at increased risk of breast cancer may help plan treatment, decrease the risk of broken bones, and help patients live more comfortably. PURPOSE: This research study is measuring bone mineral density in postmenopausal women at increased risk of developing breast cancer who are receiving exemestane on clinical trial CAN-NCIC-MAP3.

NCT05937945
Clinical trials for osteoporosis are designed to assess the safety and effectiveness of novel osteoporosis treatments. These trials play a crucial role in establishing whether these new treatments outperform existing options and provide substantial evidence to support their adoption within the wider population. The primary aim of this particular study is to investigate the experiences of individuals diagnosed with osteoporosis who participate in a distinct clinical trial involving a medical intervention. The focus will be on closely monitoring the rates of trial completion and withdrawal among these participants.
NCT04779216
This protocol is a randomized, double-blind, placebo-controlled clinical trial which aims to investigate the effect of romosozumab on BMD in women with anorexia nervosa. The investigators will also investigate the safety of romosozumab in women with anorexia nervosa. The investigators hypothesize that 12 months of romosozumab administration will result in an increase in bone mineral density, increase in markers of bone formation and decrease in markers of bone resorption, and improvement in bone microarchitecture in osteopenic women with anorexia nervosa compared with placebo. In Phase 2, participants will receive a single infusion of open-label zoledronic acid (an intravenous bisphosphonate) 5 mg after the initial 12-month administration of romosozumab or placebo. The investigators hypothesize that 12 months of romosozumab followed by a single intravenous infusion of open-label zoledronic acid will result in a greater increase in BMD compared to 12 months of placebo followed by a single intravenous infusion of open-label zoledronic acid. Within the group of women who receive sequential therapy with 12 months of romosozumab followed by a single intravenous infusion of zoledronic acid, the investigators hypothesize BMD will be maintained between 12 and 24 months following administration of zoledronic acid.
NCT00698984
The purpose of this study is to obtain information about the effect of a combination of genistein, PUFAs, vitamin K and D (BONISTEIN(R) bone blend) on bone health, determined as bone mass density/content and bone biomarkers after 6-months treatment in 70 healthy postmenopausal women. In addition, safety and tolerability will be investigated.
NCT02435147
The purpose of this study is to validate the long-term benefit of denosumab for osteoporosis treatment in a real-world clinical practice setting. We hypothesize that continued therapy (36+months) with denosumab will increase both trabecular bone score (TBS) and femur strength index (FSI) and reduce fracture and other bone health risks among post-menopausal women with osteoporosis.
NCT05721898
Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility (i.e., weakness) and an increased risk for fracture. Bone strength is a critical factor in a bone's ability to resist fracture and is clearly an important outcome in studies of osteoporosis. The current standard for assessing bone health and diagnosing osteoporosis is to use dual-energy x-ray absorptiometry (DXA) to quantify the areal bone mineral density (BMD), typically at the hip and spine. However, DXA-derived BMD has limited discriminatory accuracy for distinguishing individuals that experience fragility fracture from those who do not. One well known limitation of DXA-derived BMD is that it does not adequately assay bone strength. There is a critical unmet need to identify persons more accurately with diminished bone strength who are at high risk of experiencing a fragility fracture in order to determine an appropriate therapy. A potential new diagnostic approach to assess skeletal health and improve osteoporosis diagnosis is the use of Cortical Bone Mechanics Technology (CBMT). CBMT leverages multifrequency vibration analysis to conduct a noninvasive, dynamic 3-point bending test that makes direct, mechanical measurements of ulnar cortical bone. Data indicates that CBMT-derived ulnar flexural rigidity accurately estimates ulnar whole bone strength and provides information about cortical bone that is unique and independent of DXA-derived BMD. However, the clinical utility of CBMT-derived flexural rigidity has not yet been demonstrated. The investigators have designed a clinical study to assess the accuracy of CBMT-derived ulnar flexural rigidity in discriminating post-menopausal women who have suffered a fragility fracture from those who have not. These data will be compared to DXA-derived peripheral and central measures of BMD obtained from the same subjects.
