Efficacy and safety of teriparatide vs. bisphosphonates and denosumab vs. bisphosphonates in osteoporosis not previously treated with bisphosphonates: a systematic review and meta-analysis of randomized controlled trials. Arch Osteoporos 2024; 19:89. [PMID: 39312040 PMCID: PMC11420281 DOI: 10.1007/s11657-024-01447-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2024] [Accepted: 09/07/2024] [Indexed: 09/26/2024]
Abstract
The study found that in osteoporosis patients who had not previously received bisphosphonate treatment and were in a treatment cycle of over 12 months, both teriparatide and denosumab significantly increased bone mineral density compared to bisphosphonates. Additionally, teriparatide was also shown to significantly decrease the risk of fractures. OBJECTIVE The systematic review and meta-analysis aimed to assess and compare the safety and efficacy of teriparatide vs. bisphosphonates and denosumab vs. bisphosphonates in patients with osteoporosis who had not previously received bisphosphonates. METHODS We conducted a search of published literature from inception to May 31, 2023, including databases such as PubMed, Embase, Cochrane Library, CNKI, SinoMed, VIP, and WanFang. The study only included head-to-head randomized controlled trials (RCTs) that compared teriparatide and denosumab with bisphosphonates to treat patients with osteoporosis. Fixed-effect model and random-effect model were used due to clinical heterogeneity. Meta-analysis was performed via Stata 17.0. RESULTS A total of 6680 patients were enrolled across 23 eligible trials. The results of the meta-analysis showed that teriparatide was superior to bisphosphonates in decreasing the risk of fracture (risk ratio (RR) = 0.61, 95% confidence interval (CI) (0.51, 0.74), P < 0.001). Denosumab showed no benefit compared to bisphosphonates in reducing the risk of fracture in treating osteoporosis (RR 0.99, 95% CI (0.62, 1.57), P = 0.96). Compared with bisphosphonates, teriparatide and denosumab could significantly improve femoral neck, total hip, and lumbar spine bone mineral density (BMD) (P < 0.05). Furthermore, teriparatide and denosumab did not increase the incidence of adverse events (teriparatide vs. bisphosphonates, RR 0.92, 95% CI (0.79, 1.08), P = 0.32; denosumab vs. bisphosphonates, RR 0.98, 95% CI (0.95, 1.02), P = 0.37). CONCLUSIONS Teriparatide is superior to bisphosphonates in decreasing the risk of fracture in patients with osteoporosis. In addition, teriparatide and denosumab were more efficacious than bisphosphonates in increasing the percentage change in BMD at the femoral neck, total hip, and lumbar spine.

Real world clinical outcomes when discontinuing denosumab or bisphosphonates in patients with surgically managed osteoporotic vertebral compression fractures: a population-based cohort study. Spine J 2024:S1529-9430(24)00942-2. [PMID: 39154948 DOI: 10.1016/j.spinee.2024.08.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 07/05/2024] [Accepted: 08/09/2024] [Indexed: 08/20/2024]
Abstract
BACKGROUND CONTEXT Osteoporotic vertebral compression fractures (OVCFs) are common fragility fractures. Patients who undergo surgical treatment for their initial OVCFs warrant particular attention because there is an elevated risk of subsequent vertebral fractures and other types of fragility fractures. However, the optimal osteoporosis treatment for this specific patient group is less investigated. PURPOSE This study compares the risk of subsequent osteoporotic fractures and mortality rate for patients who are initiated with denosumab and bisphosphonates and determines the effect of adherence to treatment. STUDY DESIGN Retrospective nationwide cohort study PATIENT SAMPLE: A total of 2,858 patients who had surgically-managed osteoporotic vertebral compression fractures. OUTCOME MEASURES The risk of osteoporotic fractures, vertebral fractures, nonvertebral fractures and death. METHODS This is a retrospective nationwide cohort study that uses the National Health Insurance Research Database. Patients aged ≥50 years who were admitted for surgical interventions for OVCF between 2012 and 2016 and subsequently received denosumab or bisphosphonates for one year were included. Patients were stratified according to their antiosteoporosis medications and adherence to treatment. A multivariable, time-varying Cox proportional hazards model was used to determine the risk of osteoporotic fractures, vertebral fractures, nonvertebral fractures and death. RESULTS A total of 2,858 patients were included in this study: 1,123 patients in the denosumab group and 1,735 patients in the bisphosphonates group. Compared to persistent denosumab users, the nonpersistent denosumab users, persistent bisphosphonate users and nonpersistent bisphosphonate users had a greater risk of osteoporotic fractures, with respective hazard ratios of 1.64 (95% confidence interval [CI], 1.16-2.32), 1.74 (95% CI, 1.25-2.42) and 1.53 (95% CI, 1.14-2.06). If osteoporotic fractures were divided into nonvertebral and vertebral fractures, none of the groups exhibited an increased risk of vertebral fractures compared to persistent denosumab users, with an HR of 1.00 (95% CI: 0.54-1.88) for nonpersistent denosumab users, 1.64 (95% CI: 0.96-2.81) for persistent bisphosphonate users and 1.52 (95% CI: 0.95-2.43) for nonpersistent bisphosphonate users. However, there was a significantly greater risk of nonvertebral fracture, with respective hazard ratios of 2.04 (95% CI, 1.33-3.11), 1.80 (95% CI, 1.18-2.76) and 1.56 (95% CI, 1.06-2.27) for nonpersistent denosumab users, persistent bisphosphonate users and nonpersistent users. Noteworthy, nonpersistent denosumab users exhibited a significantly greater risk of mortality than persistent denosumab users, with a hazard ratio of 3.12 (95% CI, 2.22-4.38). CONCLUSIONS In terms of patients with OVCFs who require hospitalization and surgical intervention, those who receive ongoing denosumab treatment exhibit less risk of developing subsequent osteoporotic fractures than those who receive bisphosphonates or nonpersistent denosumab treatment. However, discontinuation of denosumab is associated with a significantly increased risk of subsequent fractures and mortality. Therefore, adherence to the treatment is crucial for patients who are initiated with denosumab.

Osteoporos Int 2024; 35:1377-1393. [PMID: 38733394 DOI: 10.1007/s00198-024-07118-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 05/03/2024] [Indexed: 05/13/2024]
Abstract
Denosumab and bisphosphonates for primary osteoporosis are generally well-tolerated, but their comparative safety remains unclear. We aimed to explore the comparative safety of denosumab and bisphosphonates in primary osteoporosis. Databases such as PubMed and Google Scholar were searched for relevant peer-reviewed randomized controlled trials published in English (as of December 2023). Trials comparing adverse events (AE) between denosumab and bisphosphonates in patients with primary osteoporosis were investigated. Data were pooled using a fixed- or random-effects model to determine the risk ratios (RR) and 95% confidence intervals (CIs) for various AEs in patients treated with denosumab in comparison to patients treated with bisphosphonates. Eleven trials (5,545 patients; follow-up period: 12-24 months) were included in this meta-analysis. All trials had a risk of bias (e.g., reporting bias linked to secondary endpoints and selection bias linked to random allocation). In comparison to bisphosphonates, denosumab was significantly associated with less withdrawal due to AEs (RR = 0.49; 95% CI 0.34-0.71), more five-point major adverse cardiovascular events (RR = 2.05; 95% CI 1.03-4.09), more cardiovascular AEs (RR = 1.61; 95% CI 1.07-2.41), more infections (RR = 1.14; 95% CI 1.02-1.27), more upper respiratory tract infections (RR = 1.56; 95% CI 1.08-2.25), less vertebral fractures (RR = 0.54; 95% CI 0.31-0.93), and less abdominal pain (RR = 0.44;95% CI 0.22-0.87). We explored the comparative safety of denosumab and bisphosphonates for primary osteoporosis, some of which could be attributed to their beneficial effects. However, all trials had a risk of bias. Further investigations are required to confirm our results.

J Clin Endocrinol Metab 2024; 109:1873-1882. [PMID: 38181430 PMCID: PMC11180512 DOI: 10.1210/clinem/dgae012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 12/12/2023] [Accepted: 01/05/2024] [Indexed: 01/07/2024]
Abstract
CONTEXT The comparative effectiveness of denosumab and zoledronic acid for adult patients with osteogenesis imperfecta (OI) has not been established. OBJECTIVE To evaluate the efficacy and safety of denosumab and zoledronic acid in adult patients with OI. METHODS This was a prospective, open-label study. Patients were randomized to receive denosumab 60 mg every 6 months or zoledronic acid 5 mg once for 12 months. Pathogenic mutations of OI were identified by next-generation sequencing and confirmed by Sanger sequencing. Percentage changes in the areal bone mineral density (aBMD), trabecular bone score (TBS), and bone turnover biomarkers (BTMs) from baseline to 6 and 12 months of treatment, as well as safety, were evaluated. RESULTS A total of 51 adults with OI (denosumab: 25, zoledronic acid: 26) were included, of whom 49 patients had identified pathogenic mutations. At 12 months, aBMD at the lumbar spine and total hip significantly increased by 4.34% (P = .005) and 1.45% (P = .023) in the denosumab group and by 4.92% (P = .006) and 2.02% (P = .016) in the zoledronic acid group, respectively. TBS showed an increasing trend by 1.39% and 2.70% in denosumab and zoledronic acid groups, respectively. Serum levels of β-isomerized carboxy-telopeptide of type I collagen and alkaline phosphatase markedly decreased after denosumab treatment. Percentage changes in aBMD, TBS, and BTMs during the treatment were similar between the 2 groups. Patients with OI with milder phenotypes showed a significantly higher increase in the TBS after 12 months of denosumab treatment than those with more severe phenotypes (P = .030). During the study period, the denosumab group had fewer adverse events than the zoledronic acid group. CONCLUSION Denosumab effectively increases aBMD in adults with OI, with similar efficacy to zoledronic acid. Long-term and large-sample studies are needed to confirm the antifracture efficacy and safety of denosumab in adult patients with OI.

Abstract
BACKGROUND Osteoporosis is a chronic progressive disease that requires lifelong monitoring and treatment. Sequencing from one treatment to another at different ages and stages of disease is an approach that can maximize benefits and avoid potential risks from long-term treatment with a single agent. OBJECTIVE This article reviews clinical trial data in postmenopausal women that evaluate the effects of antiresorptive agents followed by other antiresorptives, osteoanabolic agents followed by antiresorptives, and antiresorptives followed by osteoanabolic medications. METHODS Literature review and discussion. RESULTS When medications are discontinued, in the absence of sequential therapy, bone turnover rates return to baseline or above baseline, and bone loss occurs. The rate of bone loss differs for different treatments, with a very slow decline after stopping bisphosphonates and a particularly rapid decline after stopping denosumab. Careful attention to osteoporosis medication transitions can mitigate bone density loss and its consequences. For women who remain at high risk, switching from bisphosphonates to the more potent antiresorptive, denosumab, will result in further improvement in bone mineral density (BMD). When indicated, stopping denosumab can be accomplished safely by transition to an adequate bisphosphonate regimen. For high- and very-high-risk patients, treating with osteoanabolic agents first, followed by antiresorptive agents, produces substantially larger BMD gains than the reverse treatment sequence, with the biggest differences seen for BMD of the hip. CONCLUSION Awareness of the importance of treatment sequences can help improve osteoporosis care across the postmenopausal lifespan.

Abstract
Background: The comparison of the efficacy of zoledronate and denosumab for treating osteoporosis is controversial, and few randomized controlled trials have compared these two drugs in practical patients with acute osteoporotic vertebral compression fractures (OVCFs). We conducted a randomized controlled study to compare the efficacy of zoledronate and denosumab in patients with acute OVCF, with a focus on the occurrence of new OVCF. Methods: We enrolled 206 subjects who had their first acute OVCF, without any previous history of osteoporosis medication. The patients were randomly assigned to receive either intravenous zoledronate once a year or subcutaneous denosumab twice a year. We investigated the OVCF recurrence, clinical outcome, bone mineral density (BMD), and bone turnover markers over 12 months. Results: The final cohort comprised 89 participants (mean age of 75.82 ± 9.34 years, including 74 women [83.15%]) in the zoledronate group and 86 patients (mean age of 75.53 ± 10.23 years, including 71 women [82.56%]) in the denosumab group. New OVCFs occurred in 8 patients (8.89%) in the zoledronate group and 11 patients (12.79%) in the denosumab group (odds ratio, 1.485 [95% confidence interval, 0.567-3.891], p = 0.419). No significant difference was observed in the survival analysis between the two groups (p = 0.407). The clinical outcome, including the visual analog scale score for pain and simple radiographic findings, did not differ between the two groups. The changes in BMD and bone turnover markers were also not significantly different between the two groups. Additionally, drug-related adverse events did not differ between the groups in terms of safety. Conclusions: The efficacy of zoledronate was comparable to that of denosumab in terms of the occurrence of new OVCFs, as well as of the overall clinical course in patients with their first acute OVCF. Notably, this study represents the first comparison of these two drugs in patients with acute OVCF. However, further research with large-scale and long-term follow-up is necessary.

Abstract
OBJECTIVES The OPG/RANKL signal pathway was important regulation mechanism of bone remodeling cycle, but the effect of osteoprotegerin (OPG) and RANKL in osteoporosis was uncertain. We did a systematic review with meta-analysis to assess the association between serum OPG/RANKL and osteoporosis. METHODS The systematic search, data extraction, critical appraisal, and meta-analysis were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Randomized controlled studies were searched in PubMed, OvidMedline, Embase (1946 to present). Standard mean difference (SMD), and associated credible interval (CI) were calculated using RevMan statistical software to assess the continuous data. Heterogeneity in studies was measured by I2 values. Subgroup analysis was performed based on different bone turnover. RESULTS A total of 5 randomized controlled studies met the inclusion criteria. Both OPG and RANKL had no significant differences between the osteoporosis and control group, and the statistical heterogeneity was high in meta-analysis. However, RANKL had significant differences between the osteoporosis group with low bone turnover and control group (SMD = - 1.17; 95% CI - 1.77 to 0.57; P value < 0.01) in subanalysis. Furthermore, the OPG/RANKL ratio was significant lower in the osteoporosis group than in the control group (SMD = - 0.29; 95% CI - 0.57 to - 0.02; P value < 0.05), and the statistical heterogeneity was very low (Chi2 = 0.20, P = 0.66, I2 = 0%). CONCLUSIONS Our meta-analysis study supported OPG and RANKL were important modulatory factors of bone formation and resorption in bone turnover, respectively. Although the serum level of both OPG and RANKL were not associated with osteoporosis, but the OPG/RANKL ratio was associated with osteoporosis. In future, standardizing the test method and unit was good to clinical application.

Abstract
INTRODUCTION Osteoporosis, which is characterized by compromised bone density and heightened susceptibility to fractures, is a substantial public health concern, especially among the aging population. Underdiagnosis, undertreatment, and therapy non-adherence contribute to its impact. Anabolic and dual-action agents like teriparatide, abaloparatide, and romosozumab have emerged as effective treatments, allowing rapid gains in bone mineral density (BMD) and reducing fracture risk. However, administering treatments in the correct order is paramount, with an 'anabolic first' approach gaining traction for patients at high risk of fractures. This strategy involves starting anabolic therapies, followed by antiresorptive agents as maintenance therapy. It is important to note that the effectiveness of anabolic agents differs between treatment-naive and previously treated patients: tailored treatment approaches are therefore necessary. This comprehensive strategy adheres to clinical guidelines, emphasizing individualized care, early intervention, and patient-centered management to mitigate the burden of osteoporosis and enhance patients' quality of life. AREA COVERED The aim of this review is to summarize recent evidence on the sequential treatment of osteoporosis and to provide recommendations on the best treatment strategies. EXPERT OPINION Effective treatments, such as anabolic agents, are key in high-risk patients, who require an 'anabolic first' approach. Sequential therapy, specifically tailored to a patient's history, can help to optimize prevention and management of fractures.

Abstract
OBJECTIVE To review the comparative effectiveness of osteoporosis treatments, including the bone anabolic agents, abaloparatide and romosozumab, on reducing the risk of fractures in postmenopausal women, and to characterise the effect of antiosteoporosis drug treatments on the risk of fractures according to baseline risk factors. DESIGN Systematic review, network meta-analysis, and meta-regression analysis of randomised clinical trials. DATA SOURCES Medline, Embase, and Cochrane Library to identify randomised controlled trials published between 1 January 1996 and 24 November 2021 that examined the effect of bisphosphonates, denosumab, selective oestrogen receptor modulators, parathyroid hormone receptor agonists, and romosozumab compared with placebo or active comparator. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Randomised controlled trials that included non-Asian postmenopausal women with no restriction on age, when interventions looked at bone quality in a broad perspective. The primary outcome was clinical fractures. Secondary outcomes were vertebral, non-vertebral, hip, and major osteoporotic fractures, all cause mortality, adverse events, and serious cardiovascular adverse events. RESULTS The results were based on 69 trials (>80 000 patients). For clinical fractures, synthesis of the results showed a protective effect of bisphosphonates, parathyroid hormone receptor agonists, and romosozumab compared with placebo. Compared with parathyroid hormone receptor agonists, bisphosphonates were less effective in reducing clinical fractures (odds ratio 1.49, 95% confidence interval 1.12 to 2.00). Compared with parathyroid hormone receptor agonists and romosozumab, denosumab was less effective in reducing clinical fractures (odds ratio 1.85, 1.18 to 2.92 for denosumab v parathyroid hormone receptor agonists and 1.56, 1.02 to 2.39 for denosumab v romosozumab). An effect of all treatments on vertebral fractures compared with placebo was found. In the active treatment comparisons, denosumab, parathyroid hormone receptor agonists, and romosozumab were more effective than oral bisphosphonates in preventing vertebral fractures. The effect of all treatments was unaffected by baseline risk indicators, except for antiresorptive treatments that showed a greater reduction of clinical fractures compared with placebo with increasing mean age (number of studies=17; β=0.98, 95% confidence interval 0.96 to 0.99). No harm outcomes were seen. The certainty in the effect estimates was moderate to low for all individual outcomes, mainly because of limitations in reporting, nominally indicating a serious risk of bias and imprecision. CONCLUSIONS The evidence indicated a benefit of a range of treatments for osteoporosis in postmenopausal women for clinical and vertebral fractures. Bone anabolic treatments were more effective than bisphosphonates in the prevention of clinical and vertebral fractures, irrespective of baseline risk indicators. Hence this analysis provided no clinical evidence for restricting the use of anabolic treatment to patients with a very high risk of fractures. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42019128391.

The Effect of Zoledronic Acid on Bone Microarchitecture and Strength after Denosumab and Teriparatide Administration: DATA-HD Study Extension. J Bone Miner Res 2023; 38:26-34. [PMID: 36333954 PMCID: PMC10098948 DOI: 10.1002/jbmr.4737] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 10/12/2022] [Accepted: 11/01/2022] [Indexed: 11/06/2022]
Abstract
The combination of denosumab and teriparatide is an effective treatment strategy in postmenopausal osteoporosis, though skeletal gains are promptly lost when these agents are discontinued. In the DATA-HD study, we reported that a single dose of zoledronic acid (ZOL) maintains the increases in areal spine and hip bone mineral density (BMD) achieved with this combination for at least 12 months. The capacity of ZOL to maintain corresponding improvements in peripheral volumetric BMD and microarchitecture, however, has not been reported. In the 15-month DATA-HD study, 76 postmenopausal osteoporotic women were randomized to receive 9 months of teriparatide (20-μg or 40-μg daily) overlapped with denosumab (60 mg at months 3 and 9). In the Extension study, 53 participants received a single dose of ZOL (5 mg intravenously) 24-35 weeks after the last denosumab dose. We measured volumetric BMD and microarchitecture at the distal radius and tibia using high-resolution peripheral quantitative computed tomography at months 27 and 42. Despite ZOL administration, total and cortical BMD gradually decreased over 27 months resulting in values similar to baseline at the radius but still significantly above baseline at the tibia. At both sites, cortical porosity decreased to values below pretreatment baseline at month 27 but then increased from month 27 to 42. There were no significant changes in trabecular parameters throughout the 27-month post-ZOL observation period. Stiffness and failure load, at both sites, decreased progressively from month 15 42 though remained above baseline at the tibia. These findings suggest that in contrast to the largely maintained gains in dual-energy X-ray absorptiometry (DXA)-derived spine and hip BMD, a single dose of ZOL was not as effective in maintaining the gains in volumetric peripheral bone density and microarchitecture produced by 15 months of overlapping treatment with denosumab and teriparatide. Alternative therapeutic approaches that can fully maintain improvements in peripheral bone parameters require further study. © 2022 The Authors.

Abstract
Denosumab is a potent anti-resorptive medication used to treat patients at high risk for osteoporosis; however, its beneficial effects on the skeletal system are quickly reversed after discontinuation. In contrast, bisphosphonates (BPs) are anti-resorptive agents with residual effects on the bone matrix; thus, these are capable of preserving bone mass for a long time. Therefore, subsequent anti-resorptive treatment with BPs is mandatory to prevent rebound fractures. Furthermore, BP administration before denosumab treatment appears to be a reasonable strategy for reducing hyperactivation of bone remodeling. In this review, we summarize the effects of BP administration before denosumab treatment in preventing rebound fractures after denosumab discontinuation.

Abstract
BACKGROUND New bone-directed therapies, including denosumab, abaloparatide, and romosozumab, emerged during the past decade, and recent trends in use of these therapies are unknown. OBJECTIVE To examine temporal trends in bone-directed therapies. DESIGN An open cohort study in a US commercial insurance database, January 2009 to March 2020. PARTICIPANTS/INTERVENTIONS All-users of bone-directed therapies age >50 years, users with osteoporosis, users with malignancies, and patients with recent (within 180 days) fractures at key osteoporotic sites. MAIN MEASURES The percentage of each cohort with prescription dispensing or medication administration claims for each bone-directed therapy during each quarter of the study period. KEY RESULTS We analyzed 15.48 million prescription dispensings or medication administration claims from 1.46 million unique individuals (89% women, mean age 69 years). Among all users of bone-directed therapies, alendronate, and zoledronic acid use increased modestly (49 to 63% and 2 to 4%, respectively, during the study period). In contrast, denosumab use increased rapidly after approval in 2010, overtaking use of all other medications except alendronate by 2017 and reaching 16% of users by March 2020. Similar trends were seen in cohorts of osteoporosis, malignancy, and recent fractures. Importantly, use of any bone-directed therapy after fractures was low and declined from 15 to 8%. CONCLUSIONS Rates of denosumab use outpaced growth of all other bone-directed therapies over the past decade. Treatment rates after osteoporotic fractures were low and declined over time, highlighting major failings in osteoporosis treatment in the US.

Abstract
BACKGROUND Denosumab (DEN) and zoledronic acid (ZOL) currently represent the most potent antiresorptive agents for the treatment of osteoporosis. Despite similar effects on bone resorption, these agents have distinct mechanisms of action. The objective of this study was to compare the effect of DEN and ZOL after two-year administration on bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers, and persistence. METHODS A total of 585 postmenopausal women with osteoporosis who did not use osteoporosis medications were retrospectively reviewed. 290 patients were administered 60 mg DEN subcutaneously every 6 months from 2017 to 2018, and 295 patients were treated with 5 mg ZOL intravenously yearly from 2015 to 2017. BMD, TBS, and C-terminal cross-linking telopeptide of type 1 collagen (CTX) measurements were obtained at baseline and two-year after DEN injection or ZOL infusion. RESULTS After two-year follow-up, 188 patients in the DEN group and 183 patients in the ZOL group were compared. BMD change from baseline at two years was significantly greater in the DEN group compared with the ZOL group (P < 0.001). The changes of TBS in the DEN group were statistically significant compared with baseline (P < 0.001) and the ZOL group (P < 0.001). The DEN group led to significantly greater reduction of CTX compared with ZOL group (P = 0.041). CONCLUSION In postmenopausal women with osteoporosis, DEN was associated with greater BMD increase at all measured skeletal sites, greater increase of TBS, and greater inhibition of bone remodeling compared with ZOL.

Abstract
Although changes in serum sclerostin levels at 12 months after infusion of zoledronic acid have been reported, the changes in sclerostin levels at earlier time points are poorly understood. We reanalyzed the study data of a previous phase 1 pharmacokinetic study and investigated the correlation between changes in sclerostin levels and relevant factors in calcium metabolism. A total of 24 Japanese female subjects with primary postmenopausal osteoporosis were administered a single 4- or 5-mg dose of zoledronic acid. Serum and urine samples were collected on days 15, 29, 90, 180, and 365 after administration. Serum levels of calcium, phosphate, intact parathyroid hormone (iPTH), and sclerostin were measured. Levels of serum sclerostin were unchanged from baseline on days 15 and 29, but increased significantly on day 90, subsequently decreased significantly on day 180, and returned to baseline levels on day 365. A significant negative correlation was observed between changes in iPTH levels at early time points and sclerostin levels at later time points. This suggests that sclerostin was negatively regulated by iPTH, and the decrease in sclerostin may indicate the start of bone formation during later time points after zoledronic acid injection.

Abstract
Background Osteoporosis affects mostly postmenopausal women, leading to deterioration of the microarchitectural bone structure and low bone mass, with an increased fracture risk with associated disability, morbidity and mortality. This Bayesian network meta-analysis compared the effects of current anti-osteoporosis drugs on bone mineral density. Methods The present systematic review and network meta-analysis follows the PRISMA extension statement to report systematic reviews incorporating network meta-analyses of health care interventions. The literature search was performed in June 2021. All randomised clinical trials that have investigated the effects of two or more drug treatments on BMD for postmenopausal osteoporosis were accessed. The network comparisons were performed through the STATA Software/MP routine for Bayesian hierarchical random-effects model analysis. The inverse variance method with standardised mean difference (SMD) was used for analysis. Results Data from 64 RCTs involving 82,732 patients were retrieved. The mean follow-up was 29.7 ± 19.6 months. Denosumab resulted in a higher spine BMD (SMD −0.220; SE 3.379), followed by pamidronate (SMD −5.662; SE 2.635) and zoledronate (SMD −10.701; SE 2.871). Denosumab resulted in a higher hip BMD (SMD −0.256; SE 3.184), followed by alendronate (SMD −17.032; SE 3.191) and ibandronate (SMD −17.250; SE 2.264). Denosumab resulted in a higher femur BMD (SMD 0.097; SE 2.091), followed by alendronate (SMD −16.030; SE 1.702) and ibandronate (SMD −17.000; SE 1.679). Conclusion Denosumab results in higher spine BMD in selected women with postmenopausal osteoporosis. Denosumab had the highest influence on hip and femur BMD.

Abstract
AIMS/INTRODUCTION Patients with type 2 diabetes mellitus have a higher bone fracture risk than patients without diabetes. Although denosumab (Dmab) is a potent bone resorption inhibitor, its efficacy in patients with type 2 diabetes mellitus has not been elucidated. In this study, we investigated the effects of switching to Dmab from bisphosphonates (BP) or a selective estrogen receptor modulator (SERM) in postmenopausal type 2 diabetes mellitus patients. MATERIALS AND METHODS This was a three medical institutions, prospective, observational study for postmenopausal patients with type 2 diabetes mellitus whose T-score of femoral neck or lumbar spine bone mineral density was under -1.0 standard deviation, even after >6 months of BP or SERM administration. After obtaining consent, participants were treated for osteopenia/osteoporosis by either continuing BP (BP-BP group)/SERM (SERM-SERM group), or by switching to Dmab (BP-Dmab or SERM-Dmab groups). Changes in bone mineral density and bone metabolism marker levels were evaluated after 6 months. RESULTS A total of 48 patients were included in this study, and each group comprised 12 patients. No significant difference existed in baseline characteristics among the groups. The average age and glycated hemoglobin were 71 ± 8 years and 7.2 ± 0.9%, respectively. In the SERM-Dmab group, lumbar spine bone mineral density was significantly increased by 5.0% compared with the SERM-SERM group (P < 0.04). Serum bone-specific alkaline phosphatase and tartrate-resistant acid phosphatase 5b were significantly decreased in the BP-Dmab and SERM-Dmab groups compared with the BP-BP and SERM-SERM groups, respectively. CONCLUSIONS Switching to Dmab from BP or SERM is beneficial to prevent osteoporosis progression in postmenopausal patients with type 2 diabetes mellitus patients.

Abstract
No pharmacotherapeutic agents are yet recommended for active CN though many anti-resorptive agents have been studied. We conducted a systematic review and meta-analysis of the randomized placebo-controlled trials (RCTs) evaluating the time to remission of active CN with anti-resorptive or antiinflammatory drugs. RCTs published in PubMed, EMBASE, SCOPUS and Cochrane Library from January 1994 to December 2019 were accessed. We reviewed studies and extracted information on study design, participants' characteristics, time to remission, bone turnover markers, bone mineral content (BMC) and temperature difference between feet. Five RCTs out of 588 total identified records were included. Standardized mean differences (SMD) between groups with 95% CI are summarized. Pharmacotherapy nonsignificantly increased time to remission [SMD 0.52 weeks (- 0.71, 1.75), p = 0.402; I2 = 88.6%] as compared to TCC alone. The pooled median time to remission with the intervention was 18.5 weeks (11.2, 28.1) compared to 16.8 weeks (8.7, 27.7) with TCC. A nonsignificant increase in BMC [SMD 3.39% (- 0.78, 7.56), p = 0.109; I2 = 96.7%], a decrease in foot temperature [SMD - 0.42 °C (- 0.78, - 0.07), p = 0.020; I2 = 0%] and alkaline phosphatase [SMD = -2.51% (- 3.24, - 1.77), p < 0.001; I2 = 0%] was observed with intervention. Limited evidence from available studies does not support the role of anti-resorptive or anti-inflammatory drugs for earlier remission when added to offloading with total contact cast for active CN of the foot.

Abstract
Background Biochemical markers of bone turnover (BTMs), such as the bone alkaline phosphatase (bALP), procollagen type I N propeptide (PINP), serum cross-linked C-telopeptides of type I collagen (bCTx), and urinary cross-linked N-telopeptides of type I collagen (NTx), are used to manage therapy monitoring in osteoporotic patients. This systematic review analyzed the potential of these BMTs in predicting the clinical outcomes in terms of BMD, t-score, rate of fractures, and adverse events during the therapy setting in postmenopausal osteoporosis. Methods All randomized clinical trials (RCTs) reporting data on biomarkers for postmenopausal osteoporosis were accessed. Only articles reporting quantitative data on the level of biomarkers at baseline and on the outcomes of interest at the last follow-up were eligible. Results A total of 36,706 patients were retrieved. Greater values of bALP were associated with a greater rate of vertebral (P = 0.001) and non-vertebral fractures (P = 0.0001). Greater values of NTx at baseline were associated with a greater rate of adverse events at the last follow-up (P = 0.02). Greater values of CTx at baseline were associated with a greater rate of adverse events leading to discontinuation (P = 0.04), gastrointestinal adverse events (P = 0.0001), musculoskeletal adverse events (P = 0.04), and mortality (P = 0.04). Greater values of PINP at baseline were associated with greater rates of gastrointestinal adverse events (P = 0.02) at the last follow-up. Conclusion The present analysis supports the adoption of BMTs during pharmacological therapy setting of patients suffering from osteoporosis. Level of evidence I, systematic review of RCTs

Efficacy of Zoledronic Acid in Maintaining Areal and Volumetric Bone Density After Combined Denosumab and Teriparatide Administration: DATA-HD Study Extension. J Bone Miner Res 2021; 36:921-930. [PMID: 33507574 DOI: 10.1002/jbmr.4259] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 01/04/2021] [Accepted: 01/20/2021] [Indexed: 12/25/2022]
Abstract
Combined teriparatide and denosumab rapidly and substantially increases bone mineral density (BMD) at all anatomic sites. Discontinuation of denosumab however, results in high-turnover bone loss and increased fracture risk. The optimal way to prevent this bone loss remains undefined. This study is a preplanned extension of the DATA-HD study, where postmenopausal women with osteoporosis were randomized to receive 9 months of either 20 μg or 40 μg of teriparatide daily overlapping with denosumab (60 mg administered at months 3 and 9). At the completion of this 15-month study, women were invited to enroll in the DATA-HD Extension where they received a single dose of zoledronic acid (5 mg) 24 to 35 weeks after the last denosumab dose. Areal BMD and bone turnover markers were measured at month 27 and 42 (12 and 27 months after zoledronic acid, respectively) and spine and hip volumetric bone density by quantitative CT was measured at month 42. Fifty-three women enrolled in the DATA-HD Extension. At the femoral neck and total hip, the mean 5.6% and 5.1% gains in BMD achieved from month 0 to 15 were maintained both 12 and 27 months after zoledronic acid administration. At the spine, the mean 13.6% gain in BMD achieved from month 0 to 15 was maintained for the first 12 months but modestly decreased thereafter, resulting in a 3.0% reduction (95% CI, -4.0% to -2.0%, p < .0001) 27 months after zoledronic acid. The pattern of BMD changes between months 15 and 42 were qualitatively similar in the 20-μg and 40-μg groups. A single dose of zoledronic acid effectively maintains the large and rapid total hip and femoral neck BMD increases achieved with combination teriparatide/denosumab therapy for at least 27 months following the transition. Spine BMD was also largely, though not fully, maintained during this period. These data suggest that the DATA-HD Extension regimen may be an effective strategy in the long-term management of patients at high risk of fragility fracture. © 2021 American Society for Bone and Mineral Research (ASBMR).

A systematic review and meta-analysis of randomized controlled trials. Int J Rheum Dis 2021; 24:869-879. [PMID: 33793076 DOI: 10.1111/1756-185x.14101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 02/22/2021] [Accepted: 02/28/2021] [Indexed: 11/30/2022]
Abstract
AIM Denosumab increases bone mineral density through inhibition of the receptor activator of nuclear factor κ-Β ligand (RANKL). RANKL has known immunomodulatory effect. The largest study to date that reviewed denosumab efficacy in osteoporosis demonstrated an increased incidence of serious adverse events of infection (SAEI). We aimed to further evaluate risk of infection and SAEI in denosumab-treated patients. METHOD PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science were searched for randomized controlled trials. Studies comparing denosumab 60 mg every 6 months with placebo or bisphosphonate for treatment of low bone mineral density were included. Trials were excluded for use of denosumab in cancer patients treated for skeletal-related events, immunosuppressed patient populations, or for comparison to teriparatide. Risk ratios (RR) with a 95% confidence interval (CI) were pooled using a fixed effects model, or a random effects model if heterogeneity occurred. RESULTS Twenty-four randomized controlled trials (20 470 patients) were analyzed. An increased incidence of any infection (RR 1.11; 95% CI 1.02-1.20; P = 0.02) was observed in denosumab-treated patients compared with bisphosphonates, but not when compared with placebo. In contrast, a higher incidence of SAEI (RR 1.21; 95% CI 1.03-1.43; P = 0.02) was seen with denosumab when compared with placebo, but not compared with bisphosphonates. CONCLUSION Denosumab-treated patients with low bone mineral density have slightly increased incidence of SAEI compared with placebo, but not when compared with bisphosphonates. Application of these results requires consideration of the entire body of data available regarding denosumab safety.

Abstract
Objectives: Postmenopausal osteoporosis carries a high risk of fractures, which decrease quality of life and are associated with high morbidity, mortality, and economic burden. The best pharmacological treatment options to manage and prevent osteoporotic fractures remain still unclear. The present study investigated the efficacy and safety of the most commonly employed drugs in the management of postmenopausal osteoporosis. Methods: Only RCTs comparing different drugs for the management of postmenopausal osteoporosis were included. Data from 76 RCTs (205,011 patients) were collected. The mean follow-up was 27.6 ± 14.9 months. Results: Denosumab reported the lowest rate of non-vertebral fractures (LOR -1.57), Romosozumab the lowest rate of vertebral fractures (LOR 1.99), and Ibandronate the lowest rate of hip fractures (LOR0.18). Serious adverse events resulted in the lowest in the Raloxifene group (LOR 3.11), while those leading to study discontinuation were lowest in the Romosozumab cohort (LOR 2.65). Conclusions: Denosumab resulted in most effective, particularly in reducing the occurrence of non-vertebral fractures. Romosozumab and Ibandronate resulted best to prevent, respectively, vertebral fractures and hip fractures. Adverse events leading to study discontinuation were less frequent in the Romosozumab and Denosumab groups, while Raloxifene and Alendronate showed a lower incidence of serious adverse events overall. Level of evidence: I, Bayesian network meta-analysis of RCTs.

Abstract
CONTEXT Denosumab inhibits the receptor activator of nuclear factor κ-Β ligand, an immune system modulator. Safety endpoints including risk for infections were assessed as secondary outcomes in randomized controlled trials (RCTs) of the drug. OBJECTIVE To assess the risk of serious adverse events of infections (SAEI) in denosumab-treated patients. DATA SOURCES PubMed and Cochrane Central Register of Controlled Trials were searched up to May 27, 2019. STUDY SELECTION All RCTs of denosumab (60 mg every 6 months) versus any comparator were included. We excluded trials in cancer patients for prevention of skeletal-related events. DATA EXTRACTION Two reviewers independently applied selection criteria and extracted the data. Risk ratios (RR) with 95% confidence intervals (CI) were pooled using a fixed effect model. Sensitivity analysis was based on risk of bias. DATA SYNTHESIS Thirty-three studies (22 253 patients) were included. There was a higher incidence of SAEI during denosumab treatment versus any comparator (RR, 1.21; 95% CI, 1.04-1.40; I2 = 0%), mainly of ear, nose, and throat (RR, 2.66; 95% CI, 1.20-5.91) and gastrointestinal origin (RR, 1.43; 95% CI, 1.02-2.01). RR was similar in a sensitivity analysis based on adequate allocation concealment. The RR of any infection (RR, 1.03; 95% CI, 0.99-1.06) and infection-related mortality (RR, 0.50; 95% CI, 0.20-1.23) was comparable between groups. CONCLUSIONS A higher incidence of SAEI is demonstrated during treatment with denosumab in an osteoporosis dose. Nevertheless, the overall risk for any infection or related mortality is similar to comparator groups. These findings merit consideration before therapy initiation.

Abstract
PURPOSE To investigate changes in bone mineral density (BMD) following denosumab after previous bisphosphonate therapy and the impact of chronic kidney disease (CKD) on response. METHODS A retrospective study of 134 patients (11 M, 123 F) aged [mean (SD)] 72 [11] years on denosumab was undertaken. Ninety-five patients had previously been on oral and 28 on iv bisphosphonate. Lumbar spine (LS), total hip (TH) and femoral neck (FN) BMD were measured before treatment and at 2.7 [1.2] years. GFR was < 35 ml/min in 24 patients (18%). Ninety-four (18 M, 76 F) patients aged 71 [11] years transitioning to zoledronate were also studied. RESULTS BMD improved following denosumab [mean (SEM) % change LS: 6.0 (0.62) p < 0.001, TH: 2.28 (0.64) p < 0.001, FN: 1.9 (0.77) p = 0.045]. Changes at the TH and FN were lower in patients with GFR < 35 ml/min (Group B) compared to those with GFR > 35 ml/min (Group A) [% change TH; Group A: 2.9 (0.72), Group B: - 0.84 (1.28), p = 0.015, FN; Group A: 2.76 (0.86), Group B: - 1.47 (1.53), p = 0.025]. % change in BMD at the FN and PTH were negatively associated (r = - 0.25, p = 0.013). BMD changes were not different at 12-18 months between patients on denosumab compared to zoledronate [% change at LS: denosumab: 3.97% (0.85), zoledronate: 2.6% (0.5), p = 0.19 TH: denosumab: 0.97% (0.58), zoledronate: 0.92% (0.6), p = 0.95). CONCLUSION Denosumab increases BMD following previous bisphosphonate treatment and is comparable to zoledronate. Lower response seen at the hip in CKD is related to PTH concentrations.

Abstract
Introduction: Since postmenopausal osteoporosis is a chronic, potentially disabling condition requiring long-term treatment, the physician is expected to decide the optimal treatment strategy, e.g. how to use the available osteoanabolic and antiresorptive agents, sequentially or in combination, in the most effective and safe way, based on personalized patient care.Areas covered: Herein, the authors outline clinical data regarding the efficacy and safety of various sequential treatment strategies. More specifically, they compare the efficacy of osteoanabolic agents when they precede or follow antiresorptive treatment, as well as the efficacy of antiresorptives following other antiresorptives. Finally, the authors quote and discuss available evidence regarding the efficacy and safety of the co-administration of osteoanabolics and antiresorptives in comparison with monotherapies.Expert opinion: Initiation with an osteoanabolic agent followed by an antiresorptive seems to be the optimal treatment sequence, at least in patients with severe osteoporosis. Osteoanabolic treatment following antiresorptives seems to lead in more modest responses in bone mineral density (BMD) and bone turnover markers. Combination therapy with teriparatide and denosumab or zoledronate has achieved higher BMD gains compared to each agent alone; however, due to the high cost, combination therapy is rarely compensated. On the contrary, the combination of teriparatide with alendronate results in smaller BMD increases than TPTD monotherapy.

Abstract
Cessation of denosumab treatment is associated with increases in bone turnover above baseline values and rapid bone loss. We investigated the efficacy of zoledronate to prevent this bone loss in women with postmenopausal osteoporosis who were treated with denosumab (mean duration 2.2 years) and discontinued treatment after achieving osteopenia. Women were randomized to receive a single 5-mg infusion of zoledronate (ZOL) (n = 27) or two additional 60-mg injections of denosumab (Dmab) (n = 30). Both groups were followed for a total period of 24 months. At 24 months lumbar spine-bone mineral density (LS-BMD) was not different from baseline in the ZOL group, but decreased in the Dmab group by (mean ± SD) 4.82% ± 0.7% (p < 0.001) from the 12-month value; the difference in BMD changes between the two groups, the primary endpoint of the study, was statistically significant (p = 0.025). Results of femoral neck (FN)-BMD changes were similar. ZOL infusion was followed by small but significant increases in serum procollagen type 1 N-terminal propeptide (P1NP) and C-terminal telopeptide of type 1 collagen (CTX) during the first year and stabilization thereafter. In the Dmab group, bone turnover marker values did not change during the first 12 months but increased significantly at 15 months and in the majority of women these remained elevated at 24 months. Neither baseline nor 12-month bone turnover marker values were associated with BMD changes in either group of women. In the Dmab group, three patients sustained vertebral fractures (two patients multiple clinical, one patient morphometric) whereas one patient in the ZOL group sustained clinical vertebral fractures 12 months after the infusion. In conclusion, a single intravenous infusion of ZOL given 6 months after the last Dmab injection prevents bone loss for at least 2 years independently of the rate of bone turnover. Follow-up is recommended, because in a few patients ZOL treatment might not have the expected effect at 2 years. © 2019 American Society for Bone and Mineral Research.

Denosumab in transfusion-dependent thalassemia osteoporosis: a randomized, placebo-controlled, double-blind phase 2b clinical trial. Blood Adv 2019; 2:2837-2847. [PMID: 30381400 DOI: 10.1182/bloodadvances.2018023085] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Accepted: 08/16/2018] [Indexed: 12/20/2022] Open
Abstract
Denosumab (DNM) is a fully human monoclonal antibody against the receptor activator of nuclear factor kappa-B ligand (RANKL) that has been licensed for the treatment of different types of osteoporosis. However, the prospective data for the evaluation of DNM efficacy on transfusion-dependent thalassemia (TDT)-induced osteoporosis are rather limited. Thus, we conducted a randomized, placebo-controlled, double-blind, phase 2b clinical trial to evaluate DNM in TDT osteoporosis. Patients were assigned to receive either 60 mg DNM (n = 32) or placebo (n = 31) subcutaneously on day 0 and 180 during a total of 12 months of follow-up. The percentage increase of L1-L4 bone mineral density was higher in the DNM group than the placebo group (5.92% ± 5.25% vs 2.92% ± 5.56%, respectively; P = .043), whereas the advantage of DNM regarding wrist bone mineral density was much higher compared with placebo (-0.26% ± 5.31% vs -3.92% ± 8.71%, respectively; P = .035). No grade 3 or 4 toxicity was observed. DNM reduced pain scores that remained unaltered in the placebo group. DNM showed a significant reduction of soluble RANKL (sRANKL), sRANKL/osteoprotegerin ratio, C-telopeptide of collagen type I, tartrate-resistant acid phosphatase isoform-5b, and bone-specific alkaline phosphatase between baseline and the 12th month (P < .01 for all comparisons) without changes in dickkopf-1, sclerostin, and osteocalcin. On the contrary, placebo patients showed an increase in sRANKL, osteoprotegerin, dickkopf-1, sclerostin, C-telopeptide of collagen type I, tartrate-resistant acid phosphatase isoform-5b, and bone-specific alkaline phosphatase during the study period (P < .01 for all comparisons). In conclusion, DNM increased lumbar spine and wrist bone mineral density and reduced pain and bone remodeling markers, and thus it is another valuable option for the management of TDT-induced osteoporosis. This trial was registered at www.clinicaltrials.gov as #NCT02559648.

Abstract
Several antiresorptive drugs, like bisphosphonates and denosumab, are currently available for the treatment of osteoporosis due to their evidenced efficacy in reducing fracture risk at mid-term. Osteoanabolic therapies, like teriparatide, whose treatment duration is limited to 2 years, have also shown efficacy in the reduction of fracture risk. However, depending on the severity of osteoporosis and the presence of other associated risk factors for fracture, some patients may require long-term treatment to preserve optimal bone strength and minimize bone fracture risk. Given the limited duration of some treatments, the fact that most of the antiresorptive drugs have not been assessed beyond 10 years, and the known long-term safety issues of these drugs, including atypical femoral fractures or osteonecrosis of the jaw, the long-term management of these patients may require an approach based on drug discontinuation and/or switching. In this regard, interest in sequential osteoporosis therapy, wherein drugs are initiated and discontinued over time, has grown in recent years, although the establishment of an optimal and individualized order of therapies remains controversial. This review reports the currently available clinical evidence on the discontinuation effects of different anti-osteoporotic drugs, as well as the clinical outcomes of the different sequential treatment regimens. The objective of this article is to present up-to-date practical knowledge on this area in order to provide guidance to the clinicians involved in the management of patients with osteoporosis.

Abstract
CONTEXT It is uncertain which osteoporosis therapy is more effective: bisphosphonates or denosumab. OBJECTIVE To determine whether denosumab therapy increases bone mineral density (BMD) and reduces fracture risk more so than bisphosphonates in patients with low BMD or osteoporosis. METHODS The PubMed, Embase, and the Cochrane Library databases were searched through November 2018 for head-to-head, randomized, controlled trials comparing denosumab and bisphosphonates among adult patients with low BMD or osteoporosis. Random-effects models were used. RESULTS We identified 10 eligible trials including 5361 participants. Denosumab increased BMD more than bisphosphonate at 12 months (mean difference, 1.42%; 95% CI, 0.95% to 1.89%; P < 0.001) at lumbar spine, 1.11% (95% CI, 0.91% to 1.30%; P < 0.001) at total hip, and 1.00% (95% CI, 0.78% to 1.22%; P < 0.001) at femoral neck. At 24 months, the respective increase differences were 1.74% (95% CI, 1.05% to 2.43%; P < 0.001), 1.22% (95% CI, 0.66% to 1.77%; P < 0.001), and 1.19% (95% CI, 0.65% to 1.72%; P < 0.001). There was no difference in fracture end point at 12 months, but denosumab had a lower osteoporotic fracture incidence than alendronate at 24 months (risk ratio, 0.51; 95% CI, 0.27 to 0.97). CONCLUSION Denosumab improved BMD significantly more than bisphosphonate treatment at the lumbar spine, total hip, and femoral neck at 12 and 24 months. Only one study demonstrated greater osteoporotic fracture reduction with denosumab treatment. Longitudinal studies with longer follow-up and large sample size are needed to confirm the efficacy difference.

Abstract
INTRODUCTION Osteoporosis is the main cause of fractures among women after menopause. This study aimed to evaluate the efficacy and safety of denosumab compared to bisphosphonates in treating postmenopausal osteoporosis. METHODS Databases including PubMed and the Cochrane Central Register of Controlled Trials were systematically searched for randomised controlled trials (RCTs) that directly compared denosumab and bisphosphonates. RCTs that studied both denosumab and bisphosphonates in postmenopausal women with osteoporosis and had a Jadad score ≥ 3 were included. RESULTS Nine studies were eligible for inclusion. They were further categorised into six cohort groups. All studies had denosumab with oral bisphosphonates as the active comparator. Four out of six cohort studies showed significant improvements in bone strength (p < 0.001) at the distal radius, tibia, total hip, femoral neck, lumbar spine and trochanter at 12 months for patients on denosumab compared to the bisphosphonate group. Serum C-telopeptide of cross-linked collagen, a bone turnover marker, was consistently lower in the denosumab group in all studies. There were no significant differences in hypocalcaemia, atypical fractures, fragility fractures, osteonecrosis of the jaw, all infections (including fever or influenza-like symptoms), gastrointestinal side effects or dermatological conditions in all studies, except for one that did not document side effects. CONCLUSION Denosumab can be used both as a first-line agent and an alternative to bisphosphonate in the treatment of postmenopausal osteoporosis. There is currently insufficient data to show that denosumab is not inferior to bisphosphonates in fracture prevention.

Abstract
PURPOSE Prior osteoporosis therapies may affect the skeletal response to denosumab. We compared the effect of denosumab (60 mg every 6 months for 12 months) on bone mineral density and bone metabolism parameters in postmenopausal women with low bone mass who were either treatment-naïve (n = 30), or previously treated either with zoledronic acid (n = 30), or teriparatide (n = 22). METHODS We assessed lumbar spine bone mineral density (BMD) and measured serum concentrations of the bone turnover markers pro-collagen type 1 N-terminal propeptide (PINP) and C-terminal-cross-linking telopeptide of type 1 collagen (CTX), as well as sclerostin, dickkopf-1 (Dkk-1), and myostatin. RESULTS Lumbar spine BMD increased equivalently in all three groups after 12 months of denosumab compared to baseline (p < 0.001). Serum PINP and CTX decreased significantly with denosumab in pre-treated women reaching the same nadir levels as in treatment-naïve patients (p < 0.001). Women pre-treated with teriparatide displayed lower baseline myostatin concentrations as compared to the other two groups (p < 0.001). Changes in lumbar spine BMD in teriparatide pre-treated women correlated with changes in bone turnover markers and myostatin. CONCLUSIONS Denosumab induced similar increases in lumbar spine BMD in treatment-naïve and pre-treated patients and suppressed serum PINP and CTX to the same levels regardless of prior treatments. In teriparatide pre-treated patients the magnitude of change in bone turnover markers is associated with BMD response.

Abstract
Sclerostin knock-out mice or sclerostin antibody (Scl-Ab) treated wild-type mice displayed decreased marrow adiposity. But the effects of Scl-Ab on estrogen deficiency-induced marrow fat expansion remain elusive. In this work, 45 female New Zealand rabbits were equally divided into sham-operation, ovariectomy controls, and ovariectomy treated with Scl-Ab for 5 months. MR spectroscopy was performed to longitudinally assess marrow fat fraction at baseline conditions, 2.5 and 5 months post-operatively, respectively. We evaluated bone mineral density (BMD), bone structural parameters, serum bone biomarkers, and quantitative parameters of marrow adipocytes. Ovariectomized rabbits markedly exhibited expansion of marrow fat in a time-dependent manner, with a variation of marrow fat fraction (+17.8%) at 2.5 months relative to baseline and it was maintained until 5 months (+30.4%, all P < 0.001), which was accompanied by diminished BMD and deterioration of trabecular microstructure. Compared to sham controls, adipocyte mean diameter, adipocyte density and adipocytes area percentage was increased by 42.9, 68.3, and 108.6% in ovariectomized rabbits, respectively. Scl-Ab treatment increased serum bone formation marker and alleviated the ovariectomy escalation of serum bone resorption marker. It remarkably lessened the ovariectomy-mediated deterioration of BMD, and morphometric characteristics of trabecular bone. Marrow fat fraction was decreased significantly with Scl-Ab to levels matching that of sham-operated controls and correlated positively with reductions in adipocyte mean diameter, percentage adipocyte volume per marrow volume, and adipocyte density. Taken together, early Scl-Ab treatment reverts marrow fat expansion seen in ovariectomized rabbits in addition to having a beneficial effect on bone mass and microstructural properties.

Abstract
The most widely used medications for the treatment of osteoporosis are currently bisphosphonates (BPs) and denosumab (Dmab). Both are antiresorptives, thus targeting the osteoclast and inhibiting bone resorption. Dmab achieves greater suppression of bone turnover and greater increases of bone mineral density (BMD) at all skeletal sites, both in naïve and pretreated patients. No superiority on fracture risk reduction has been documented so far. In long-term administration, BPs reach a plateau in BMD response after 2-3 years, especially at the hip, while BMD increases progressively for as long as Dmab is administered. Both BPs and Dmab are generally considered safe, although they have been correlated to rare adverse events, such as osteonecrosis of the jaw and atypical femoral fractures. Dmab should be preferred in patients with impaired renal function. BPs are embedded in the bone, from which they are slowly released during bone remodeling, therefore continuing to act for years after their discontinuation. In contrast, Dmab discontinuation fully and rapidly reverses its effects on bone markers and BMD and increases the risk for fractures; therefore, Dmab discontinuation should be discouraged, especially in previously treatment-naïve patients, regardless of the conventional fracture risk. In case of discontinuation, other treatment, mainly BPs, should immediately follow, although the optimal sequential treatment strategy is yet to be defined. Combination of teriparatide with Dmab or zoledronic acid, but not alendronate, provides increased BMD gains at all sites. In conclusion, both BPs and Dmab are safe and efficient therapeutic options although their particularities should be carefully considered in an individual basis.

Abstract
Sclerostin (SOST) is a Wnt signaling inhibitor detrimental to osteogenic differentiation and bone mineral acquisition. While control of SOST action delays the pathogenesis of skeletal disorders, the effects of SOST vaccination on the estrogen deficiency-induced bone deterioration remain elusive. In this study, we generated a SOST-Fc fusion protein which was composed of a SOST peptide Pro-Asn-Ala-Ile-Gly along with an IgG Fc fragment. SOST-Fc vaccination increased serum anti-SOST antibody levels and reduced serum SOST concentrations in mice. In vitro, anti-SOST serum attenuated the SOST-induced inhibition of osteogenic gene expression in osteoblast cultures. Administration with SOST-Fc increased serum levels of bone formation marker osteocalcin and alleviated the ovariectomy escalation of serum resorption markers CTX-1 and TRAP5b concentrations. It remarkably lessened the estrogen deficiency-mediated deterioration of bone mineral density, morphometric characteristics of trabecular bone, and mechanical strength of femurs and lumbar spines. The SOST-Fc-treated skeletal tissue exhibited moderate responses to the adverse actions of ovariectomy to bone mineral accretion, osteoclast surface, trabecular separation, and fatty marrow histopathology. SOST-Fc treatment increased serum osteoclast-inhibitory factor osteoprotegrin levels in conjunction with strong Wnt3a, β-catenin, and TCF4 immunostaining in osteoblasts, whereas it weakened the estrogen deficiency enhancement of osteoclast-promoting factor receptor activator of nuclear factor-κB ligand. Taken together, blockade of SOST action by SOST-Fc vaccination sustains Wnt signaling, which harmonizes bone mineral accretion and resorption reactions and thereby ameliorates ovariectomy-induced bone loss. This study highlights SOST-Fc fusion protein as a new molecular therapeutic potential for preventing from osteoporotic disorders.

Abstract
Zoledronic acid is regarded as the most potent bisphosphonate and is widely used in patients with osteoporosis; however, its side effects, including acute-phase reactions, gastrointestinal complaints, renal dysfunction and bisphosphonate-associated osteonecrosis impair the safety and quality of life of patients. The present study was designed to determine the minimal effective concentration of zoledronic acid through testing the dose-dependent effects of zoledronic acid on osteoclast suppression. A primary culture of bone marrow mononuclear cells obtained from C57 mice (age, 6 weeks) was established and induced to form osteoclasts. The number of multinuclear cells was determined by tartrate-resistant acid phosphatase staining and compared among cultured marrow cells treated with different concentrations of zoledronic acid. Furthermore, the cellular properties, including adhesion, migration and bone resorption, were compared at the minimal effective concentration. At a concentration of 1×10−6 mol/l, zoledronic acid significantly inhibited the formation of osteoclasts. This inhibitory effect was further enhanced at the concentration of 1×10−5 mol/l. However, the inhibitory effect of zoledronic acid tapered at the concentration of 1×10−4 mol/l and there was no further dose-dependent increase. In addition, the concentration of 1×10−6 mol/l was sufficient to alter cellular functions, including cell adhesion, migration and bone resorption. In conclusion, zoledronic acid was effective in reducing osteoclast formation and suppressing cellular functions. The minimal effective concentration of zoledronic acid in vitro was 1 µmol/l. Based on these results, a comparable dosage should be explored in clinical applications.

Abstract
Background: Due to the severity of the primary disease in patients with lung cancer, quality of life (QoL) is often overlooked. Factors that form QoL should be taken in consideration when planning the appropriate treatment and determining therapy targets, because of the increasing frequency of bone metastasis leading to high levels of pain. Purpose of this study is to assess quality of life in patients with lung cancer, before and after treatment combined with zoledronic acid. Methods and materials: QoL was assessed in 80 patients (49 males-31 females), of which 45 developed bone metastasis. Prior and post treatment (with co administration of zoledronic acid) seven reliable scales: Pittsburgh Sleep Quality index (PSQI), Epworth Sleeping Scale (ess), Dyspnea Scale (ds), Fatigue Severity Scale (FSS), Brief Pain Inventory (BPI), Fact-G scale for sleep quality and EQ-5D for general health condition. Results: Statistically positive correlations were verified between PSQI-DS, PSQI-FSS, BPI-ESS, DS-FSS, DS-BPI and BPI-FSS (p<0,005) prior and post treatment. Patients sleep quality was improved, pain levels decreased and betterment in quality of life was marked (p<0,001). Although significant decrease in fatigue levels was observed (p<0,001) there has been an increase in dyspnea symptoms (p<0,001). Conclusions: Significant improvement was apparent when zoledronic acid was co administered in any treatment in patients with lung cancer. Sleep quality, fatigue and pain parameters also improved, with no positive impact on the symptoms of dyspnea.

Abstract
INTRODUCTION Denosumab is a monoclonal antibody that received approval by the FDA for the treatment of osteoporosis in 2010. Available higher level research evidence concerns the treatment of patients that have not received any anti-osteoporotic medication in the past. Further investigation is warranted, since clinicians often face the challenge of administering the most efficacious drug in patients, pretreated with other medications. AREAS COVERED We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of denosumab compared to other active anti-osteoporotic agents in patients formerly receiving other treatments. We searched MEDLINE, EMBASE, CENTRAL, the metaRegister of Controlled Trials (mRCT) and clinicaltrials.gov up to April 2017 to identify eligible trials in patients with primary osteoporosis. EXPERT OPINION Our meta-analysis included 6 Randomised Controlled Trials encompassing 2968 patients formerly treated with anti-osteoporotic medications. Quantitative data synthesis demonstrated superiority of denosumab in augmenting Bone Mineral Density in all skeletal sites studied compared to controls [treatment difference in total hip: 1.59% (95% CI 1.01, 2.17)], whereas the overall incidence of serious adverse events was not increased (OR 1.12, 95% CI 0.85 to 1.47, p = 0.42). Future research geared towards the fracture incidence, quality of life and patient reported outcomes is warranted.

Abstract
Post-menopausal osteoporosis (PMOP) is a metabolic bone disorder characterized by low bone mass and micro-architectural deterioration of bone tissue. The over-activated osteoclastogenesis, which plays an important role in osteoporosis, has become an important therapeutic target. M54 was a bioactive derivative of the Chinese traditional herb matrine. We found that M54 could suppress RANKL-induced osteoclastogenesis in bone marrow mononuclear cells and RAW264.7 cells through suppressing NF-κB, PI3K/AKT, and MAPKs pathways activity in vitro, and prevent ovariectomy-induced bone loss in vivo. Our previous study has proved that ribosomal protein S5 (RPS5) was a direct target of M19, based on which M54 was synthesized. Thus we deduced that M54 also targeted RPS5. During osteoclastogenesis, the RPS5 level in RAW264.7 cells was significantly down-regulated while M54 could maintain its level. After RPS5 was silenced, the inhibitory effects of M54 on osteoclastogenesis were partially compromised, indicating that M54 took effects through targeting RPS5. In summary, M54 was a potential clinical medicine for post-menopause osteoporosis treatment, and RPS5 is a possible key protein in PMOP.

Abstract
Bone turnover comprises two processes: the removal of old bone (resorption) and the laying down of new bone (formation). N-terminal propeptide of type I procollagen (PINP) and C-telopeptide of type I collagen (CTX-I) are markers of bone formation and resorption, respectively, that are recommended for clinical use. Bone turnover markers can be measured on several occasions in one individual with good precision. However, these markers are subject to several sources of variability, including feeding (resorption decreases) and recent fracture (all markers increase for several months). Bone turnover markers are not used for diagnosis of osteoporosis and do not improve prediction of bone loss or fracture within an individual. In untreated women, very high bone turnover marker concentrations suggest secondary causes of high bone turnover (eg, bone metastases or multiple myeloma). In people with osteoporosis, bone turnover markers might be useful to assess the response to anabolic and antiresorptive therapies, to assess compliance to therapy, or to indicate possible secondary osteoporosis. Much remains to be learnt about how bone turnover markers can be used to monitor the effect of stopping bisphosphonate therapy (eg, to identify a threshold above which restarting therapy should be considered). More studies are needed to investigate the use of bone turnover markers for assessment of the bone safety of new medications.

Effect of recent spinal cord injury on the OPG/RANKL system and its relationship with bone loss and the response to denosumab therapy. Osteoporos Int 2017; 28:2707-2715.

Abstract
UNLABELLED There is marked bone loss after spinal cord injury (SCI); however, its pathogenesis and clinical management remain unclear. The increased circulating levels of receptor activator of nuclear factor kB ligand (RANKL) associated with bone loss shortly after SCI and the prevention of bone loss with denosumab treatment suggest a contributory role of RANKL in SCI-induced osteoporosis. INTRODUCTION Bone turnover and bone loss are markedly increased shortly after SCI. However, the pathogenesis and clinical management of this process remain unclear, especially the role of the osteoprotegerin (OPG)/RANKL system in this disorder. The aim of this study was to analyze serum levels of OPG and RANKL in bone loss associated with recent SCI and the effect of denosumab treatment on these mediators. METHODS Twenty-three males with recent complete SCI were prospectively included. Serum OPG and RANKL levels, bone turnover markers (PINP, bone ALP, CTX), and bone mineral density (BMD) were assessed at baseline, at 6 months of follow-up, prior to initiating denosumab, and 6 months after treatment. The results were compared with a healthy control group. RESULTS At baseline, SCI patients showed higher RANKL levels vs. controls which were correlated with days-since-SCI and total hip BMD loss at 6 months. OPG levels were similar to controls at baseline. After denosumab treatment, OPG showed no changes, whereas RANKL levels became undetectable in 67% of patients. Patients with undetectable RANKL during treatment showed better response in femoral BMD and bone markers vs. patients with detectable RANKL at 6 months of denosumab. Increased parathormone (PTH) levels during treatment were negatively correlated with RANKL changes. CONCLUSIONS RANKL levels are increased after SCI and related to BMD loss at the proximal femur, becoming undetectable after denosumab treatment. The effect of denosumab on preventing sublesional bone loss, especially in patients with undetectable levels during treatment, suggests a contributory role of RANKL in this process.

Increased osteoclastogenesis in patients with vertebral fractures following discontinuation of denosumab treatment. Eur J Endocrinol 2017; 176:677-683.

Abstract
OBJECTIVE To test the hypothesis that rebound of bone remodeling is responsible for clinical vertebral fractures reported in a few patients with osteoporosis after cessation of denosumab treatment. DESIGN In this case-control study we compared clinical and biochemical characteristics of postmenopausal women with clinical vertebral fractures 8-16 months after the last injection of denosumab (Dmab/Fx+, n = 5) with those of treatment-naïve women with such fractures (Fx+, n = 5). In addition, 5 women who discontinued denosumab treatment but did not sustain vertebral fractures 18-20 months after the last injection were studied (Dmab/Fx-, n = 5). METHODS We measured serum microRNAs, gene expression of mRNAs of factors regulating formation and activity of osteoclasts and biochemical markers of bone and mineral metabolism. In Dmab/Fx+ and Fx+ women, blood was taken 4-8 weeks after the fracture. RESULTS Compared to Fx+ women, Dmab/Fx+ women had higher serum P1NP and CTx levels, and significantly lower serum miR-503 and miR-222-2 that downregulate osteoclastogenesis and osteoclast activity, and higher RANK (13-fold) and CTSK (2.6-fold) mRNA. The respective values of Dmab/Fx- women were in the same direction as those of Dmab/Fx+ women but of a lesser magnitude. CONCLUSIONS Bone fragility in women with clinical vertebral fractures after stopping denosumab therapy is pathophysiologically different from that of treatment-naïve women with osteoporosis and clinical vertebral fractures and it is associated with upregulation of markers of osteoclast formation and activity. The small number of women with this rare event studied is a limitation.

Abstract
BACKGROUND While changes in biochemical markers of bone turnover (BTM) have been reported to predict changes in bone mineral density (BMD), the relationship between changes in BMD and BTMs with combined antiresorptive/anabolic therapy is unknown. METHODS In the DATA study, 94 postmenopausal osteoporotic women (ages 51-91) received either teriparatide 20-mcg SC daily, denosumab 60-mg SC every 6months, or both for 2years. Pearson's correlation coefficients (R) were calculated to determine the relationship between baseline and early changes in BTMs (as well as serum sclerostin) and 2-year changes in BMD. RESULTS In women receiving teriparatide, baseline BTMs did not correlate with 2-year BMD changes though 12-month increases in osteocalcin and P1NP were associated with 2-year increases in spine BMD. In women receiving denosumab, spine and hip BMD gains correlated with both baseline and changes in P1NP and C-telopeptide. In women receiving combined teriparatide/denosumab, while both baseline and decreases in P1NP were associated with spine BMD gains, distal radius increases were associated with less CTX suppression. Neither baseline nor changes in serum sclerostin correlated with BMD in any treatment group. SUMMARY AND CONCLUSIONS In women treated with teriparatide or denosumab, early BTM changes (increases and decreases, respectively) predict 2-year BMD gains, especially at the spine. In women treated with combined teriparatide/denosumab therapy, BMD increases at the distal radius were associated with less suppression of bone turnover. These results suggest that efficacy of combination therapy at cortical sites such as the radius may depend on residual bone remodeling despite RANKL inhibition.

Abstract
Bisphosphonates are used to treat bone disease characterised by increased bone resorption by inhibiting the activity of mature osteoclasts, resulting in decreased bone turnover. Bisphosphonates may also reduce the population of osteoclast precursor cells. Our aims were to investigate the effect of bisphosphonates on i) osteoclast precursor cells and ii) circulating cytokine and cytokine receptor in postmenopausal women with osteoporosis compared with healthy premenopausal women. Participants were 62 postmenopausal women (mean age 66) from a 48-week parallel group trial of bisphosphonates. They received ibandronate 150mg/month (n=22), alendronate 70mg/week (n=19) or risedronate 35mg/week (n=21). Fasting blood was collected at baseline, weeks 1 and 48. At baseline, blood was also collected from 25 healthy premenopausal women (mean age 37) to constitute a control group. Peripheral blood mononuclear cells were extracted and stained for CD14, M-CSFR, CD11b and TNFRII receptors. Flow cytometry was used to identify cells expressing CD14+ and M-CSFR+ or CD11b+ or TNFRII+. RANKL and OPG were measured to evaluate potential mediation of the bisphosphonate effect. After 48weeks of treatment, there was a decrease in the percentage of cells expressing M-CSFR and CD11b receptors by 53% and 49% respectively (p<0.01). Cells expressing M-CSFR and CD11b were decreased with ibandronate and risedronate after 48weeks to the lower part of the premenopausal reference interval. These effects were not significantly different between each of the treatment groups. There was no significant effect on RANKL and OPG throughout the study period. Bisphosphonates inhibit bone resorption in the short-term by direct action on mature osteoclasts. There is also a later effect mediated in part by a reduction in the population of circulating osteoclast precursors.

Abstract
Osteoporosis, which is characterized by resorption of bone exceeding formation, remains a significant human health concern, and the impact of this condition will only increase with the "graying" of the worldwide population. This review focuses on current and emerging approaches for delivering therapeutic agents to restore bone remodeling homeostasis. Well-known antiresorptive and anabolic agents, such as estrogen, estrogen analogs, bisphosphonates, calcitonin, and parathyroid hormone, along with newer modulators and antibodies, are primarily administered orally, intravenously, or subcutaneously. Although these treatments can be effective, continuing problems include patient noncompliance and adverse systemic or remote-site effects. Controlled drug delivery via polymeric, targeted, and active release systems extends drug half-life by shielding against premature degradation and improves bioavailability while also providing prolonged, sustained, or intermittent release at therapeutic doses to more effectively treat osteoporosis and associated fracture risk.

Abstract
Since the identification of osteoporosis as a major health issue in aging populations and the subsequent development of the first treatment modalities for its management, considerable progress has been made in our understanding of the mechanisms controlling bone turnover and disease pathophysiology, thus enabling the pinpointing of new targets for intervention. This progress, along with advances in biotechnology, has rendered possible the development of ever more sophisticated treatments employing novel mechanisms of action. Denosumab, a monoclonal antibody against RANKL, approved for the treatment of postmenopausal and male osteoporosis, significantly and continuously increases bone mineral density (BMD) and maintains a low risk of vertebral, non-vertebral, and hip fractures for up to 8 years. Currently available combinations of estrogens with selective estrogen receptor modulators moderately increase BMD without causing the extra-skeletal adverse effects of each compound alone. The cathepsin K inhibitor odanacatib has recently been shown to decrease vertebral, non-vertebral, and hip fracture rates and is nearing approval. Romosozumab, an anti-sclerosin antibody, and abaloparatide, a PTH-related peptide analog, are at present in advanced stages of clinical evaluation, so far demonstrating efficaciousness together with a favorable safety profile. Several other agents are currently in earlier clinical and preclinical phases of development, including dickkopf-1 antagonists, activin A antagonists, β-arrestin analogs, calcilytics, and Src tyrosine kinase inhibitors.
