Senolytics to Improve Osteoporosis Therapy
OsteopeniaOsteoporosisThis randomised clinical trial aims to study osteoporosis as a disease of accelerated skeletal aging caused by the accumulation of senescent cells within the skeleton and investigate the effects and safety of senolytics and antioxidant therapy on bone.
Finding the Optimal Resistance Training Intensity For Your Bones
OsteoporosisOsteopeniaOsteoporosis is a bone disease that can result in fractures, disability and an increased risk of premature death. Exercise is recommended for fall and fracture prevention, but health care professionals often recommend walking or lower intensity community exercise classes, which may not be effective for building bone. Further, individuals with osteoporosis are often told to avoid lifting or moving in certain ways, which creates fear and activity avoidance. Conversely, research suggests that to stimulate bone, you need higher loads on bone, with either higher intensity resistance training or impact exercise - the types of things people with low bone mass are told to avoid. Our study will examine different types of exercise intensity and how they translate to building bone in people with low bone mineral density (BMD).
Effect of Anti-osteoporotic Medications on Nonalcoholic Fatty Liver Disease
Nonalcoholic Fatty LiverOsteoporosis1 moreNonalcoholic fatty liver disease (NAFLD) is a chronic, metabolic liver disease that is closely related to obesity, type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) in a bidirectional mode. NAFLD affects approximately 25% of the worldwide population. NAFLD refers to a phenotypic spectrum, including steatosis, inflammation and fibrosis, which can lead to cirrhosis and hepatocellular carcinoma in a minority of patients. However, despite its high prevalence, morbidity and mortality, as well as the extensive research in the field, there is not to-date a licensed medication specifically for NAFLD. Emerging evidence supports a potential association between NAFLD and osteoporosis; the prevalence of osteoporosis is probably higher in patients with NAFLD and, vise versa, the prevalence of NAFLD may be higher in patients with osteoporosis. In this context, it has been proposed that certain medications for osteoporosis may also prove to be beneficial to NAFLD. Denosumab, a human monoclonal IgG2 antibody against the receptor activator of nuclear factor kappa-B (NF-κB) ligand (RANKL), is currently an established treatment for osteoporosis and other metabolic bone diseases. The axis RANKL-receptor activator of nuclear factor NF-κB (RANK)-osteoprotegerin (OPG) has been demonstrated as a key regulator of bone metabolism and, when dysregulated, it contributes to the pathogenesis of osteoporosis and other metabolic bone diseases. Interestingly, experimental studies have shown that circulating and hepatic RANKL may be upregulated in mice with diet-induced NAFLD, rendering RANKL a potential contributor to the pathogenesis of NAFLD, and ideally, a promising pharmacological target. On the other hand, bisphosphonates, another established, first-line treatment for osteoporosis, are expected to have no significant effect on hepatic metabolism in patients with NAFLD due to their pharmacokinetics and mechanism of action. This is a prospective non-randomized study which aims to investigate the comparative effect of denosumab versus bisphosphonates on hepatic steatosis and fibrosis in women with postmenopausal osteoporosis and concomitant NAFLD.
Multifaceted Intervention Using Telehealth to Reduce the Risk of Falls and Fractures in Older Men...
OsteoporosisOsteoporotic Fractures5 moreMen sustain over one-third of osteoporosis-related fractures worldwide. The burden of osteoporotic fractures in older men is substantial, and men suffer significantly worse fracture-related outcomes than women. Following a fracture, men sustain greater rates of subsequent fractures, loss of autonomy, and mortality than women and the imminent risk of re-fracture is several times higher in men than in women. Functional mobility, known to predict falls and fractures, is also notably worse in men following a fracture. In the fiscal year 2007-08, the overall annual costs of osteoporosis in Canadian men was evaluated to be $910 million. Osteoporosis is primarily considered a disease of older women, and men are remarkably under-evaluated and under-treated for it. Recognition of sex and gender influences on skeletal health in men has been very slow; akin to the gap in cardiovascular diseases, where women are far less likely to receive guideline-recommended investigations and treatment. Over 85% of Canadian men who suffer from fragility fractures do not receive osteoporosis screening and/or treatment strategies. The existence of this care gap in men underscores our current struggle to overcome important barriers including: 1) men's lack of awareness of the critical impact of osteoporosis and fractures on several aspects of their lives, and of the benefits of treatment; and 2) the absence of comprehensive and accessible treatments tailored to men. Informed by the Knowledge-to-Action framework, we aim to address these barriers by adapting interventions with proven efficacy to engage men at high fracture risk in health behaviour change. The current protocol is for a pilot RCT to determine the feasibility of recruitment and retention, adherence to, and acceptability of the virtually-delivered fracture prevention intervention only. Our long-term goal is to conduct a large pragmatic randomized controlled trial (RCT) to address the research question: In older adults at high risk for fractures who self-identify as men, does anti-osteoporosis pharmacotherapy in conjunction with a virtually-delivered intervention that includes a gender-tailored strength training and balance based exercise program and nutritional counselling, improve functional mobility compared to anti-osteoporosis pharmacotherapy in conjunction with an attention control intervention.
Denosumab Biosimilar Injection in Post Menopausal Women With Osteoporosis
OsteoporosisPostmenopausalDenosumab of Intas is biosimilar denosumab candidate under development by Intas Pharmaceutical Limited (Biopharma Division). Denosumab of Intas is already approved by Indian drug licensing authority- Drug Controller General (India) for marketing in Indian population since 2018.As per regulatory requirement, a comparative clinical study to establish Pharmacokinetic, Pharmacodynamic and Immunogenicity equivalence is required to conclude therapeutic equivalence to obtain marketing authorization of a biosimilar investigational product. This is a multicenter, randomized, double-blind, active controlled study in approximately 552postmenopausal women with osteoporosis. An extension of the study is planned after completion of the initial 1 year of treatment. This extension is with the objective of submitting data on safety, and Immunogenicity, after switching of Prolia treatment arm to either Prolia or Intas denosumab for 6 months. This switching data is applicable only for FDA submission. Only patients who have undergone PK assessment will be eligible for the extension phase.
The Effectiveness of Eldecalcitol in the Bisphosphonate Non-respondered-patients With Osteoporosis...
OsteoporosisIn the patients with osteoporosis, bisphosphonates (BPs) are a golden standard treatment. However, the bone turnover markers or the bone mineral density (BMD) are not improved in some osteoporotic patients even though they have taken BPs and alfacalcidol more than several years. In those case, the investigators better off prescribing BPs and Eldecalcitol, instead of BPs and Alfacalcitol.
Examination of Efficacy and Safety of Other Anti-Resorption Drugs After 2-year-Denosumab Therapy...
OsteoporosisThe aim of this study is to examine the efficacy and adverse events in the following 3 groups in Japanese osteoporosis patients after 2-year-denosumab therapy: SERM and eldecalcitol treatment for 24 months Bisphosphonates and eldecalcitol treatment for 24 months Eldecalcitol treatment for 24 months
Influence of Dermocorticoids on Bone Mineral Density in Patients With Bullous Pemphigoid
OsteoporosisBullous PemphigoidBullous pemphigoid is the most common type of bullous skin disease and is clinically characterized by clear-tense bullae, which result in post-bullous cutaneous erosions, altering the skin barrier. The treatment of this pathology consists of the application of high doses of topical corticosteroids (clobetasol propionate) for a prolonged period of at least 6 months. The main objective of this study is to demonstrate a change in bone mineral density at 6 months after initiation of treatment, in subjects with bullous pemphigoid and treated with topical corticosteroid.
Bone Loss Prevention With Zoledronic Acid or Denosumab in Critically Ill Adults
Critical IllnessOsteoporosisThe Bone Zone trial is a prospective, multi-centre, double-blind, phase II, randomised controlled trial evaluating the effect of denosumab or zoledronic acid compared to placebo on change in bone mineral density over one year in women aged 50 years or older and men aged 70 years or older requiring admission to intensive care for greater than 24 hours. 450 women aged 50 years or older and men aged 70 years or older, admitted to intensive care for greater than 24 hours will be recruited into the study from participating study centres.
Novel Precision Medicine Approach to Treatment of Osteoporosis Based on Bone Turnover
Age-Related OsteoporosisOsteoporosis affects 24.5% of women over 65 and results in fracture-related hospital admissions exceeding those of heart attacks, strokes and breast cancer combined. Current treatment options do not account for differences between age-related and estrogen deficiency related osteoporosis, because of the need for bone biopsies for determination. This study will establish a paradigm-shifting individualized treatment protocol for age-related osteoporosis and a non-invasive method for its determination, thereby reducing the major health problems and enormous burden on society and the elderly related to this disease.
