Atypical Fracture Cohort Study
Atypical Femur FractureAtypical Subtrochanteric Fracture1 moreOsteoporosis is a disease characterized by increased bone fragility and deteriorating bone micro-architecture. The main consequence of osteoporosis is low-trauma fractures, most often of the hip, spine and wrist. Recently, another type of low-trauma fracture, atypical femur fractures (AFFs), have received much attention. Little is known of the cause of these debilitating fractures; however, they have been associated with long term bisphosphonate use. What we currently know about AFFs is based on case reports or small case series, or studies using administrative databases or secondary analyses of bisphosphonate trials. While these reports provide some preliminary information on the relationship between long term bisphosphonate exposure and AFFs, detailed clinical data are absent. As we have established a network of specialists across southern Ontario our group is in a position to collect meaningful information on a larger group of patients who have experienced these debilitating fractures into a centralized AFF registry.
Comparison of the Effect of an Ongoing Treatment With Alendronate or a Drug Holiday on the Fracture...
OsteoporosisThe purpose of this study is to evaluate the efficacy and safety of bisphosphonates in long term treatment of osteoporosis.
A Dose-Ranging Study of MK-5442 in Postmenopausal Women With Osteoporosis (MK-5442-001)
OsteoporosisThe purpose of this study was to identify an appropriate dose of MK-5442 that produced an osteoanabolic effect without causing hypercalcemia in postmenopausal women with osteoporosis.
An Investigation Into the Short Term Effect of APOMINE in Patients With Osteoporosis or Low Bone...
OsteoporosisOsteoporosis affects millions of postmenopausal women in the USA. The current approved treatments are all drugs that prevent bone loss and possibly result in small gains in bone mass. Another possible treatment consists of drugs that increase bone formation. There are currently two drugs that stimulate bone formation, sodium fluoride and human parathyroid hormone (hPTH). Neither of these two drugs has been approved by the FDA. APOMINE has shown significant bone formation in animal studies. In this study we plan to test whether APOMINE is able to stimulate new bone formation in women with osteoporosis or low bone mass.
Comparation of Treatment Strategies for OVF: Teriparatide Injection and PVP
OsteoporosisPostmenopausal2 moreThis study aimed to compare teriparatide treatments and PVPs, focusing on its effects on life qualities and effect/coast ratio and evaluate which method is better for patients.
Circulating miRNA in Primary Hyperparathyroidism
Primary HyperparathyroidismOsteoporosis1 moreThe goal of this study is to: 1. Analyze the expression levels of circulating (serum) miRNAs in primary hyperparathyroidism patients with and without osteoporosis, and patients with osteoporosis undergoing thyroidectomy, and to correlate with clinical markers of bone remodeling including biochemical and radiologic studies. 2. To evaluate serum miRNA levels after treatment with parathyroidectomy.
Alendronate in an Weekly Effervescent Tablet Formulation Following Denosumab Discontinuation
Postmenopausal OsteoporosisDiscontinuation of denosumab results in a rebound response of bone turnover markers, which rise above baseline at 3 months and remain elevated until reaching again baseline levels approximately 30 months after the last dose. Bone mineral density (BMD) gains are also lost and BMD values reach original baseline values after 1-2 years off-treatment.For the above reasons, current literature recommends that patients who discontinue denosumab should continue to receive either intravenous (iv) or oral (peros) bisphosphonate therapy for some time. The study aims to investigate changes in the BMD of the lumbar spine 12 months after transitioning from denosumab to oral alendronate 70 mg in a weekly effervescent tablet formulation
The Effects of 12-months of Denosumab on Bone Density in Prevalent Kidney Transplant Recipients...
OsteoporosisRenal Osteodystrophy1 moreThis is a Phase 2 Multi-Center Clinical Trial (safety and effectiveness trial) in 60 patients (40 denosumab; 20 placebo) who have had a kidney transplant for 12-months or longer with more than 30% of kidney function. The investigators will test whether denosumab safely improves bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) and improves bone strength by high resolution peripheral quantitative computed tomography (HR-pQCT) in the subset of patients recruited at Columbia University Irving Medical Center. These data will inform the development and execution of a larger trial to test if denosumab prevents fractures in kidney transplant recipients.
Yogurt Supplementation to Alter Bone Biomarkers, the Gut Microbiota and Inflammation in Older Adults...
OsteoporosisInflammationCaribbean Latino adults are a vulnerable population at risk for developing osteoporosis. In addition to lifestyle factors, such as dietary intake, the investigators hypothesize that a unhealthy gut microbial environment coupled with high inflammation contributes to the risk of developing osteoporosis. There has been little research conducted on mechanisms underpinning how a low-intensity dietary intervention, including supplementation with daily yogurt, can affect the gut health of Caribbean Latino adults. The study objectives are to: 1) determine whether daily yogurt supplementation reduces bone turnover (biomarkers of overall bone health) and inflammation compared to a control group that maintains their usual diet (void of yogurt); and 2) collect preliminary data on the effects of daily yogurt supplementation on the gut microbiome compared to diet control group.
Study and Follow-up of the Clinical Effectiveness and Comparative Safety of Biosimilar Teriparatide...
OsteoporosisNon-interventional observational prospective follow-up study of cohorts of patients with Previous diagnosis of Osteoporosis with high risk of fractures, with/without previous fractures and treatment with bone formers (biosimilar or original Teriparatide), who meet all the inclusion criteria and exclusion, with prior information and signing of prior informed consent documents.
