Bisphosphonates for Prevention of Post-Denosumab Bone Loss

IOPOsteoporosis

The primary goal of the study is to assess the extent to which bisphosphonate therapy will prevent decreases in bone mass that may occur after cessation of denosumab in premenopausal women with idiopathic osteoporosis (IOP) enrolled in AAAN0161 (FD05114) "Denosumab for the prevention of post-teriparatide bone loss in premenopausal women with idiopathic osteoporosis". In addition, the investigator will observe participants for a second year off bisphosphonate therapy to assess duration of response. The hypothesis is that bisphosphonate therapy with alendronate or zoledronic acid, initiated after recovery of bone remodeling activity, will prevent significant bone loss after discontinuing denosumab.

A Study to Evaluate the Efficacy and Safety of HLX14 vs. Denosumab Prolia® in Postmenopausal Women...

Postmenopausal

This is a randomized, double-blind, international multicentre, parallel-controlled phase III clinical study. The study plans to enroll 478 postmenopausal women with osteoporosis at high risk of fracture, whom will be randomized at 1:1 to either the experiment group (HLX14) or the control group (Prolia®) based on stratification factors (BMI (< 25, 25-30, > 30) and geographic region (Asian or non-Asian)). The study includes screening period (28 days), treatment period (total 546 days, contain treatment period 1: D1-D364, treatment period 2: D365-D546), and an end-of-study visit (D547).

Effects of DHEA and Exercise on Bone Marrow Fat in Postmenopausal Women

Low Bone DensityOsteoporosis

Bone strength -the main determinant of bone fracture- is a function not only of bone mineral density (BMD) and microstructure, but also of its microenvironment, including bone marrow fat (BMF). The adrenal steroid dehydroepiandrosterone (DHEA) -the main precursor for estrogens and androgens in postmenopausal women- as well as bone-loading exercise, increase BMD in older women, however, their effects on BMF are largely unknown. This study has high potential to unveil the hormonal and mechanical effects of DHEA and exercise on BMF, respectively, and to elucidate longitudinal associations of BMF with bone strength in older women with bone loss.

Alendronate Treatment of Osteoporosis in Rheumatoid Arthritis

Rheumatoid ArthritisOsteoporosis

A randomized, double-blind, placebo-controlled trial including 160 consecutive patients who have been diagnosed with both rheumatoid arthritis (RA) and low bone mass and have been treated with alendronate (ALN) for five years or more. Patients will be randomized to discontinuation or continuation of alendronate. Outcomes are measured using dual energy absorptiometry (DXA), High Resolution peripheral Quantitative Computer Tomography (HR-pQCT) and biochemical markers of bone metabolism and inflammation after 6 months, 1 and 2 years.

Bone Microarchitecture in Men With Hemophilia

Severe Hemophilia AOsteoporosis

Hemophilia A and B are hereditary sex-linked deficiencies of coagulation factors VIII and IX characterized by bleeding. Their modern therapy increases life expectancy and risk of age-related diseases, e.g., osteoporosis. Hemophilia-specific risk factors impair formation of peak bone mass and accelerate bone loss. Fractures are more frequent in hemophilic men vs. age-matched men and induce bleeding which is aggravated by manipulations and surgical intervention. The hypothesis of this study is that hemophilic men have poor bone microarchitecture (assessed by High-resolution peripheral quantitative computed tomography (HR-pQCT)) related to an imbalance between bone formation and resorption (assessed by bone turnover markers (BTM) and bone biomarkers). The study aims to assess the difference in low trabecular number (Tb.N) at the distal radius between hemophilic men (cases) and age- height-weight-ethnicity and smoking-matched healthy men (controls). Correlation between BTM and Tb.N will be also studied. Biologic markers of bone remodeling (C-terminal telopeptide of type I collagen (PINP), N-terminal propeptide of type I procollagen (CTX-I), periostin) will be studied.

Treatment With Romosozumab to Improve Bone Mineral Density and Architecture in Chronic SCI

OsteoporosisSpinal Cord Injuries

The objective of the proposed work is to determine whether administration for 12 months of romosozumab (evenity) followed by 12 months of denosumab (prolia) will maintain bone mass at the knee in subjects with chronic SCI.

Exercise Mode and Bone

OsteoporosisAging

Endurance exercise is often recommended to improve cardiometabolic health and maintain bone health throughout life and to prevent osteoporotic fracture. However, there is evidence to suggest that bone does not always adapt in the way that is expected, and that endurance exercise may lead to bone loss under certain conditions. Disruptions in calcium homeostasis during exercise may explain this observation, and preliminary data suggests that the mode of exercise (i.e., cycling versus treadmill) may result in different magnitudes of change in bone biomarkers. The purpose of this study is to determine if mode of exercise results in a differential bone biomarker response to an acute exercise bout in older Veterans. Blood samples will be collected before, during, and after 2 acute exercise bouts: 1) brisk treadmill walking; and 2) vigorous stationary cycling. Bouts will be matched for relative intensity and duration. This data will be used to develop future exercise interventions in older Veterans aimed at preserving both cardiometabolic and bone health.

Mode of Exercise and Bone Biomarkers in Older Veterans

AgingMusculoskeletal Diseases1 more

Adults are often encouraged to exercise to maintain or improve bone health. However, there is evidence that exercise does not always lead to increases in bone mass, and exercise could lead to bone loss under certain conditions. Endurance exercise can increase bone resorption following an exercise bout, which may explain why bone does not always favorably adapt to exercise, but it is unclear if this also happens with resistance exercise. Further, it is not known how exercise training influences blood markers of bone resorption for either endurance or resistance exercise. The purpose of this study is to determine 1) if resistance exercise causes a similar increase in bone resorption as endurance exercise; and 2) if exercise training influences the increase in bone resorption following exercise for both endurance and resistance exercise.
