Abstract
UNLABELLED The FREEDOM study and its Extension provide long-term information about the effects of denosumab for the treatment of postmenopausal osteoporosis. Treatment for up to 8 years was associated with persistent reduction of bone turnover, continued increases in bone mineral density, low fracture incidence, and a favorable benefit/risk profile. INTRODUCTION This study aims to report the results through year 5 of the FREEDOM Extension study, representing up to 8 years of continued denosumab treatment in postmenopausal women with osteoporosis. METHODS Women who completed the 3-year FREEDOM study were eligible to enter the 7-year open-label FREEDOM Extension in which all participants are scheduled to receive denosumab, since placebo assignment was discontinued for ethical reasons. A total of 4550 women enrolled in the Extension (2343 long-term; 2207 cross-over). In this analysis, women in the long-term and cross-over groups received denosumab for up to 8 and 5 years, respectively. RESULTS Throughout the Extension, sustained reduction of bone turnover markers (BTMs) was observed in both groups. In the long-term group, mean bone mineral density (BMD) continued to increase significantly at each time point measured, for cumulative 8-year gains of 18.4 and 8.3 % at the lumbar spine and total hip, respectively. In the cross-over group, mean BMD increased significantly from the Extension baseline for 5-year cumulative gains of 13.1 and 6.2 % at the lumbar spine and total hip, respectively. The yearly incidence of new vertebral and nonvertebral fractures remained low in both groups. The incidence of adverse and serious adverse events did not increase over time. Through Extension year 5, eight events of osteonecrosis of the jaw and two events of atypical femoral fracture were confirmed. CONCLUSIONS Denosumab treatment for up to 8 years was associated with persistent reductions of BTMs, continued BMD gains, low fracture incidence, and a consistent safety profile.

Abstract
Osteonecrosis of the jaw (ONJ) has been associated with antiresorptive therapy in both oncology and osteoporosis patients. This debilitating condition is very rare and advances in diagnosis and management may now effectively reduce the risk of its development and offer valuable treatment options for affected patients. This paper provides a case-based review of ONJ and application of the International Task Force on ONJ (referred to as the "Task Force") recommendations for the diagnosis and management of ONJ. The Task Force was supported by 14 international societies and achieved consensus from representatives of these multidisciplinary societies on key issues pertaining to the diagnosis and management of ONJ. The frequency of ONJ in oncology patients receiving oncology doses of bisphosphonate (BP) or denosumab is estimated at 1%-15%, and the frequency in the osteoporosis patient population receiving much lower doses of BP or denosumab is estimated at 0.001%-0.01%. Although the diagnosis of ONJ is primarily clinical, imaging may be helpful in confirming the diagnosis and staging. In those with multiple risk factors for ONJ for whom major invasive oral surgery is being planned, interruption of BP or denosumab therapy (in cancer patients) is advised, if possible, before surgery, until the surgical site heals. Major oral surgery in this context could include multiple extractions if surgical extractions are required, not simple forceps extractions. ONJ development may be reduced by optimizing oral hygiene and postoperatively using topical and systemic antibiotics as appropriate. Periodontal disease should be managed before starting oncology doses of BP or denosumab. Local debridement may be successful in disease unresponsive to conservative therapy. Successful surgical intervention has been reported in those with stage 3 disease; less severe disease is best managed conservatively. Teriparatide may be helpful in healing ONJ lesions and may be considered in osteoporosis patients at a high fracture risk in the absence of contraindications. Resumption of BP or denosumab therapy following healing of ONJ lesions is recommended, and there have not been reports of subsequent local recurrence.

Abstract
UNLABELLED Stopping denosumab after 8 years of continued treatment was associated with bone loss during a 1-year observation study in patients who were not prescribed osteoporosis treatment. Bone loss was attenuated in patients who began another osteoporosis therapy. Treatment to prevent bone loss upon stopping denosumab should be considered. INTRODUCTION This study aimed to understand osteoporosis management strategies during a 1-year observational follow-up after up to 8 years of denosumab treatment in a phase 2 study. METHODS During the observational year, patients received osteoporosis management at the discretion of their physician and returned to the clinic for BMD assessment and completion of an osteoporosis management questionnaire. Incidence of serious adverse events and fractures was collected. Analyses were descriptive. RESULTS Of 138 eligible patients, 82 enrolled in and completed the observation study. Most (65 [79%]) did not receive prescription osteoporosis medication, with "my doctor felt I no longer needed a medication" being the most common reason (23 [35%]). Of the 17 patients who took osteoporosis medications, 8 discontinued therapy during the observation study. In patients treated with denosumab for 8 years (N = 52), BMD decreased during the 1-year observation study (6.7% [lumbar spine], 6.6% [total hip]). Those who took osteoporosis medication during the observation study showed a smaller decline in BMD than those who did not. No new safety concerns were identified. Eight patients (9.8%), all of whom had at least one predisposing risk factor, experienced 17 fractures. This included seven patients who experienced one or more vertebral fractures. CONCLUSIONS Consistent with denosumab's mechanism of action, treatment cessation led to reversal of the drug's effect on BMD and perhaps fracture risk. For patients who took osteoporosis therapy, bone loss was attenuated. For patients at high fracture risk, switching to another osteoporosis therapy if denosumab is discontinued seems appropriate.

Abstract
BACKGROUND The prevalence of osteoporosis is increasing in the United States. PURPOSE To evaluate low bone mass and osteoporosis treatments to prevent fractures. DATA SOURCES Ovid MEDLINE ALL, Ovid Evidence Based Medicine Reviews: Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov from 2014 through February 2022. STUDY SELECTION Adults receiving eligible interventions for low bone mass or osteoporosis. Randomized controlled trials (RCTs) for fracture outcomes, and RCTs and large observational studies (n ≥1000) for harms. DATA EXTRACTION Abstracted by 1 reviewer and verified by a second. Independent, dual assessments of risk of bias and certainty of evidence (CoE). DATA SYNTHESIS We included 34 RCTs (in 100 publications) and 36 observational studies. Bisphosphonates and denosumab reduced hip, clinical and radiographic vertebral, and other clinical fractures in postmenopausal females with osteoporosis (moderate to high CoE). Bisphosphonates for 36 months or more may increase the risk for atypical femoral fractures (AFFs) and osteonecrosis of the jaw (ONJ), but the absolute risks were low. Abaloparatide and teriparatide reduced clinical and radiographic vertebral fractures but increased the risk for withdrawals due to adverse events (WAEs; moderate to high CoE). Raloxifene and bazedoxifene for 36 months or more reduced radiographic vertebral but not clinical fractures (low to moderate CoE). Abaloparatide, teriparatide, and sequential romosozumab, then alendronate, may be more effective than bisphosphonates in reducing clinical fractures for 17 to 24 months in older postmenopausal females at very high fracture risk (low to moderate CoE). Bisphosphonates may reduce clinical fractures in older females with low bone mass (low CoE) and radiographic vertebral fractures in males with osteoporosis (low to moderate CoE). LIMITATION Few studies examined participants with low bone mass, males, or Black-identifying persons, sequential therapy, or treatment beyond 3 years. CONCLUSION Bisphosphonates, denosumab, abaloparatide, teriparatide, and romosozumab, followed by alendronate, reduce clinical fractures in postmenopausal females with osteoporosis. Abaloparatide and teriparatide increased WAEs; longer duration bisphosphonate use may increase AFF and ONJ risk though these events were rare. PRIMARY FUNDING SOURCE American College of Physicians.

Abstract
BACKGROUND Denosumab, a RANK-ligand inhibitor, is an effective treatment for osteoporosis in postmenopausal women and men. Unlike the bisphosphonates, it is not excreted by the kidney. Little is known, however, about its efficacy and safety in patients with severe chronic kidney disease (CKD). METHODS A retrospective study was performed in CKD 4-5D patients from a tertiary referral hospital who were treated with denosumab between 1st January 2011 and 31st March 2014. Data collected included information about the following: CKD stage, fracture history, bone mineral density, serum calcium levels pre and post denosumab treatment, episodes of hypocalcemia, relevant medications and adverse events. RESULTS Eight patients with CKD-5 and 6 patients with CKD-4 were identified (all female, mean age 77.1 ± 9.9). The mean pre-denosumab calcium value was 2.42 ± 0.12 mmol/l, PTH 20.2 ± 14.7 pmol/l and 25-OH vitamin D 69.1 ± 30.1 nmol/l. After denosumab treatment, 6/8 patients with CKD-5/5D, and 2/5 patients with CKD-4 developed severe hypocalcemia. Two patients developed direct adverse complications of hypocalcemia (seizure, laryngospasm, prolonged QTc). Among the patients who developed hypocalcemia, the median time to serum calcium nadir was 21 days and the median time to correction of hypocalcemia was 71 days. Treatment of hypocalcemia required large doses of oral calcium and calcitriol, and increases in dialysate calcium concentration. CONCLUSIONS A high rate of severe hypocalcemia was observed in patients with advanced CKD treated with denosumab. If denosumab is used in patients with severe CKD, close monitoring and aggressive replacement of calcium and calcitriol is required to avoid the development of hypocalcemia.

Abstract
IMPORTANCE Hypercalcemia affects approximately 1% of the worldwide population. Mild hypercalcemia, defined as total calcium of less than 12 mg/dL (<3 mmol/L) or ionized calcium of 5.6 to 8.0 mg/dL (1.4-2 mmol/L), is usually asymptomatic but may be associated with constitutional symptoms such as fatigue and constipation in approximately 20% of people. Hypercalcemia that is severe, defined as total calcium of 14 mg/dL or greater (>3.5 mmol/L) or ionized calcium of 10 mg/dL or greater (≥2.5 mmol/L) or that develops rapidly over days to weeks, can cause nausea, vomiting, dehydration, confusion, somnolence, and coma. OBSERVATIONS Approximately 90% of people with hypercalcemia have primary hyperparathyroidism (PHPT) or malignancy. Additional causes of hypercalcemia include granulomatous disease such as sarcoidosis, endocrinopathies such as thyroid disease, immobilization, genetic disorders, and medications such as thiazide diuretics and supplements such as calcium, vitamin D, or vitamin A. Hypercalcemia has been associated with sodium-glucose cotransporter 2 protein inhibitors, immune checkpoint inhibitors, denosumab discontinuation, SARS-CoV-2, ketogenic diets, and extreme exercise, but these account for less than 1% of causes. Serum intact parathyroid hormone (PTH), the most important initial test to evaluate hypercalcemia, distinguishes PTH-dependent from PTH-independent causes. In a patient with hypercalcemia, an elevated or normal PTH concentration is consistent with PHPT, while a suppressed PTH level (<20 pg/mL depending on assay) indicates another cause. Mild hypercalcemia usually does not need acute intervention. If due to PHPT, parathyroidectomy may be considered depending on age, serum calcium level, and kidney or skeletal involvement. In patients older than 50 years with serum calcium levels less than 1 mg above the upper normal limit and no evidence of skeletal or kidney disease, observation may be appropriate. Initial therapy of symptomatic or severe hypercalcemia consists of hydration and intravenous bisphosphonates, such as zoledronic acid or pamidronate. In patients with kidney failure, denosumab and dialysis may be indicated. Glucocorticoids may be used as primary treatment when hypercalcemia is due to excessive intestinal calcium absorption (vitamin D intoxication, granulomatous disorders, some lymphomas). Treatment reduces serum calcium and improves symptoms, at least transiently. The underlying cause of hypercalcemia should be identified and treated. The prognosis for asymptomatic PHPT is excellent with either medical or surgical management. Hypercalcemia of malignancy is associated with poor survival. CONCLUSIONS AND RELEVANCE Mild hypercalcemia is typically asymptomatic, while severe hypercalcemia is associated with nausea, vomiting, dehydration, confusion, somnolence, and coma. Asymptomatic hypercalcemia due to primary hyperparathyroidism is managed with parathyroidectomy or observation with monitoring, while severe hypercalcemia is typically treated with hydration and intravenous bisphosphonates.

Abstract
BACKGROUND Osteoporosis and cardiovascular (CV) diseases are closely correlated. RANKL/RANK/OPG pathway and Wnt signalling pathway both implicated in the pathogenesis of osteoporosis and cardiovascular diseases. We aimed to investigate the effect of denosumab or romosozumab therapy on cardiovascular outcomes in patients with primary osteoporosis. METHODS PubMed, Cochrane library, and EMBASE databases were systematically searched from the inception dates to June 4, 2019. Randomized clinical trials evaluating the effect of denosumab or romosozumab versus active comparators or placebo for at least 6 months in patients with primary osteoporosis or osteopenia were included. Two investigators independently extracted data for study characteristics, outcomes of interest, and risk of bias in accordance with PRISMA guidelines. RESULTS 17 relevant studies (denosumab: n=11, 13615 participants; romosozumab: n=6, 12219 participants) were included. No associations between denosumab therapy and risk of a composite cardiovascular outcome (1.06 [95 % CI, 0.88-1.28], p=0.54), three-point major adverse cardiovascular event (3P MACE, 1.01 [95 % CI, 0.83-1.23], p=0.93), and four-point major adverse cardiovascular event (4P MACE, 0.99 [95 % CI, 0.83-1.18], p=0.89) were identified. Romosozumab therapy did not increase the risk of composite cardiovascular outcome (1.26 [95 % CI, 0.95-1.68], p=0.11), and 3P MACE (1.41 [95 % CI, 0.99-2.02], p=0.06), while increased the risk of 4P MACE (1.39 [95 % CI, 1.01-1.90], p=0.04) among elderly men and postmenopausal woman with osteoporosis over a period of 12-36 months. Denosumab or romosozumab did not increase or reduce specific cardiovascular outcomes, including CV death or death, myocardial infarction, stroke, atrial fibrillation, heart failure, aortic and intracranial aneurysm, aortic dissection, aortic valve disease and hypertension (all p>0.05). Sensitivity analysis conducted by random effects model altered the result of 4P MACE in romosozumab (1.36 [0.99-1.87], p=0.06). No other significant difference was detected in the sensitivity analyses and subgroup analyses. CONCLUSIONS Denosumab therapy was not associated with any risk of composite and specific cardiovascular outcomes among patients with primary osteoporosis than active comparators or placebo, while romosozumab therapy might increase the risk of 4P MACE.

Abstract
UNLABELLED Persistence with and adherence to osteoporosis therapy are critical for fracture reduction. This non-interventional study is evaluating medication-taking behavior of women with postmenopausal osteoporosis (PMO) receiving denosumab in Germany, Austria, Greece, and Belgium. Patients were representative of the PMO population and highly persistent with and adherent to denosumab at 12 months. INTRODUCTION Persistence with and adherence to osteoporosis therapy are important for optimal treatment efficacy, namely fracture reduction. This ongoing, non-interventional study will evaluate medication-taking behavior of women with postmenopausal osteoporosis (PMO) receiving denosumab in routine practice in four European countries. METHODS The study enrolled women who had been prescribed subcutaneous denosumab (60 mg every 6 months) in accordance with prescribing information and local guidelines. Persistence was defined as receiving the subsequent injection within 6 months + 8 weeks of the previous injection. Adherence was defined as receiving two consecutive injections within 6 months ± 4 weeks of each other. Medication coverage ratio (MCR) was calculated using the time a patient was covered with denosumab, as assessed from prescription records. Treatment was assigned prior to and independently of enrollment; outcomes are recorded during routine practice. RESULTS These planned 12-month interim analyses included data from 1500 patients from 141 sites. Mean age was 66.4-72.4 years, mean baseline total hip T-scores ranged from -2.0 to -2.1 and femoral neck T-scores from -2.2 to -2.6, and 30.7-62.1% of patients had prior osteoporotic fracture. Persistence was 87.0-95.3%, adherence 82.7-89.3%, and MCR 91.3-95.4%. In a univariate analysis, increased age, decreased mobility, and increased distance to the clinic were associated with significantly decreased persistence; parental history of hip fracture was associated with significantly increased persistence. CONCLUSIONS These data extend the real-world evidence regarding persistence with and adherence to denosumab, both of which are critical for favorable clinical outcomes, including fracture risk reduction.

Abstract
PURPOSE OF REVIEW Denosumab discontinuation is associated with a rebound effect manifesting by an increased risk of multiple spontaneous vertebral fractures. The purpose of this review is to (1) better characterize this risk and (2) find solutions to avoid it. RECENT FINDINGS In the absence of a potent bisphosphonate prescription at denosumab discontinuation, the frequency of multiple vertebral fractures is common or frequent (≥ 1/100 and < 1/10). In five recent case series, the median number of vertebral fractures was 5 within 7 to 20 months (median 11) after the last denosumab injection. Prescribing bisphosphonate before starting denosumab and/or after stopping denosumab may reduce this risk. However, only small case series have evaluated these strategies. After the second denosumab dose, there is a rebound effect with an increased risk of multiple vertebral fractures. A potent bisphosphonate prescribed at denosumab discontinuation could reduce this risk. As denosumab discontinuation is characterized by many uncertainties, denosumab is a second-line treatment for osteoporosis. Studies are urgently needed to define the management of denosumab discontinuation.

Abstract
BACKGROUND Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse reaction experienced by some individuals to certain medicines commonly used in the treatment of cancer and osteoporosis (e.g. bisphosphonates, denosumab and antiangiogenic agents) and involves the progressive destruction of bone in the mandible or maxilla. Depending on the drug, its dosage, and the duration of exposure, the occurrence of this adverse drug reaction may be rare (e.g. following the oral administration of bisphosphonate or denosumab treatments for osteoporosis, or antiangiogenic agent-targeted cancer treatment) or common (e.g. following intravenous bisphosphonate for cancer treatment). MRONJ is associated with significant morbidity, adversely affects quality of life (QoL), and is challenging to treat. OBJECTIVES To assess the effects of interventions versus no treatment, placebo, or an active control for the prophylaxis of MRONJ in people exposed to antiresorptive or antiangiogenic drugs.To assess the effects of non-surgical or surgical interventions (either singly or in combination) versus no treatment, placebo, or an active control for the treatment of people with manifest MRONJ. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 23 November 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 10), MEDLINE Ovid (1946 to 23 November 2016), and Embase Ovid (23 May 2016 to 23 November 2016). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on language or publication status when searching the electronic databases; however, the search of Embase was restricted to the last six months due to the Cochrane Embase Project to identify all clinical trials and add them to CENTRAL. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing one modality of intervention with another for the prevention or treatment of MRONJ. For 'prophylaxis of MRONJ', the primary outcome of interest was the incidence of MRONJ; secondary outcomes were QoL, time-to-event, and rate of complications and side effects of the intervention. For 'treatment of established MRONJ', the primary outcome of interest was healing of MRONJ; secondary outcomes were QoL, recurrence, and rate of complications and side effects of the intervention. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results, extracted the data, and assessed the risk of bias in the included studies. For dichotomous outcomes, we reported the risk ratio (RR) (or rate ratio) and 95% confidence intervals (CI). MAIN RESULTS We included five RCTs (1218 participants) in the review. Three trials focused on the prophylaxis of MRONJ. Two trials investigated options for the treatment of established MRONJ. The RCTs included only participants treated with bisphosphonates and, thus, did not cover the entire spectrum of medications associated with MRONJ. Prophylaxis of MRONJOne trial compared standard care with regular dental examinations in three-month intervals and preventive treatments (including antibiotics before dental extractions and the use of techniques for wound closure that avoid exposure and contamination of bone) in men with metastatic prostate cancer treated with zoledronic acid. The intervention seemed to lower the risk of MRONJ: RR 0.10; 95% CI 0.02 to 0.39 (253 participants; low-quality evidence). Secondary outcomes were not evaluated.As dentoalveolar surgery is considered a common predisposing event for developing MRONJ, one trial investigated the effect of plasma rich in growth factors (PRGF) for preventing MRONJ in people with cancer undergoing dental extractions. There was insufficient evidence to support or refute a benefit of PRGF on MRONJ incidence when compared with standard treatment (RR 0.08, 95% CI 0.00 to 1.51; 176 participants; very low-quality evidence). Secondary outcomes were not reported. In another trial comparing wound closure by primary intention with wound closure by secondary intention after dental extractions in people treated with oral bisphosphonates (700 participants), no cases of intraoperative complications or postoperative MRONJ were observed. QoL was not investigated. Treatment of MRONJOne trial analysed hyperbaric oxygen (HBO) treatment used in addition to standard care (antiseptic rinses, antibiotics, and surgery) compared with standard care alone. HBO in addition to standard care did not significantly improve healing from MRONJ compared with standard care alone (at last follow-up: RR 1.56; 95% CI 0.77 to 3.18; 46 participants included in the analysis; very low-quality evidence). QoL data were presented qualitatively as intragroup comparisons; hence, an effect estimate of treatment on QoL was not possible. Other secondary outcomes were not reported.The other RCT found no significant difference between autofluorescence- and tetracycline fluorescence-guided sequestrectomy for the surgical treatment of MRONJ at any timepoint (at one-year follow-up: RR 1.05; 95% CI 0.86 to 1.30; 34 participants included in the analysis; very low-quality evidence). Secondary outcomes were not reported. AUTHORS' CONCLUSIONS Prophylaxis of MRONJOne open-label RCT provided some evidence that dental examinations in three-month intervals and preventive treatments may be more effective than standard care for reducing the incidence of MRONJ in individuals taking intravenous bisphosphonates for advanced cancer. We assessed the certainty of the evidence to be low.There is insufficient evidence to either claim or refute a benefit of either of the interventions tested for prophylaxis of MRONJ (i.e. PRGF inserted into the postextraction alveolus during dental extractions, and wound closure by primary or secondary intention after dental extractions). Treatment of MRONJAvailable evidence is insufficient to either claim or refute a benefit for hyperbaric oxygen therapy as an adjunct to conventional therapy. There is also insufficient evidence to draw conclusions about autofluorescence-guided versus tetracycline fluorescence-guided bone surgery.

Abstract
UNLABELLED Root amputation, immunosuppressive therapy, mandibular tooth extraction, pre-existing inflammation, and longer duration of treatment with bone-modifying agents were significantly associated with an increased risk of medication-related osteonecrosis of the jaw. Hopeless teeth should be extracted without drug holiday before the development of inflammation in cancer patients receiving high-dose bone-modifying agents. INTRODUCTION No studies have comprehensively analyzed the influence of pre-existing inflammation, surgical procedure-related factors such as primary wound closure, demographic factors, and drug holiday on the incidence of medication-related osteonecrosis of the jaw (MRONJ). The purpose of this study was to retrospectively investigate the relationships between these various factors and the development of MRONJ after tooth extraction in cancer patients receiving high-dose bone-modifying agents (BMAs) such as bisphosphonates or denosumab. METHODS Risk factors for MRONJ after tooth extraction were evaluated with univariate and multivariate analyses. The following parameters were investigated in all patients: demographics, type and duration of BMA use, whether BMA use was discontinued before tooth extraction (drug holiday), the duration of such discontinuation, the presence of pre-existing inflammation, and whether additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. RESULTS We found that root amputation (OR = 22.62), immunosuppressive therapy (OR = 16.61), extraction of mandibular teeth (OR = 12.14), extraction of teeth with pre-existing inflammation, and longer duration (≥ 8 months) of high-dose BMA (OR = 7.85) were all significantly associated with MRONJ. CONCLUSIONS Tooth extraction should not necessarily be postponed in cancer patients receiving high-dose BMA. The effectiveness of a short-term drug holiday was not confirmed, as drug holidays had no significant impact on MRONJ incidence. Tooth extraction may be acceptable during high-dose BMA therapy until 8 months after initiation.

Abstract
This article provides the best current frequency estimate of medication-related osteonecrosis of the jaws (MRONJ), and identifies factors associated with the risk of developing osteonecrosis of the jaw (ONJ) among patients exposed to relevant medications (ie, antiresorptive or antiangiogenic agents). MRONJ is a rare but serious complication of cancer treatment or osteoporosis management. This review confirms that antiresorptive medications such as oral or intravenous bisphosphonates and denosumab are the most common risk factors for developing ONJ. The risk of MRONJ is greater in patients with cancer than in those receiving antiresorptive treatments for osteoporosis by a factor of 10.

Abstract
A 10-year-old boy diagnosed with unresectable giant cell tumor of bone in the sacrum was treated with a bone modifying agent denosumab. Administration of denosumab showed excellent clinical response without any major complications, and the tumor was surgically removed afterwards. However, 4 months after discontinuing denosumab, the patient developed severe hypercalcemia (15.2 mg/dl). There was a sharp surge in the levels of bone resorption markers, indicating that disregulated overt bone resorption after the discontinuation of denosumab led to hypercalcemia. The patient was treated with bisphosphonate and barely recovered from the life-threatening conditions. This case shows that a robust rebound of bone resorption may occur following cessation of denosumab and suggests that hypercalcemia is an underappreciated side effect of denosumab therapy in children.

Abstract
BACKGROUND Although giant cell tumors (GCTs) are benign, their aggressiveness and tendency to recur locally challenge the orthopaedic surgeon's ability to perform joint-preserving intralesional surgery with an acceptably low risk of local recurrence. Denosumab has emerged as a possible medical treatment of GCT because it seems to halt the progression of GCT, alleviate pain, and increase perilesional bone formation, but its exact role has been questioned, and specifically its efficacy and associated complications are not well characterized. QUESTIONS/PURPOSES (1) Does denosumab reduce the risk of recurrence after resection or intralesional surgery? (2) What are the complications associated with the use of denosumab? METHODS Fifty-four patients with 30 primary and 25 recurrent tumors between November 2013 and July 2016 were treated with denosumab after a confirmed histopathologic diagnosis of GCT. Another 17 patients in the same period were treated without denosumab. During the study period, we encouraged the use of denosumab in all patients except those who refused, could not afford it, or where it was contraindicated (eg, in pregnancy). In all patients undergoing intralesional surgery, we arbitrarily planned six doses before surgery. Variations in total doses before surgery were dependent on patient-related factors; in some, we gave less doses because patients expressed the inability to afford any more doses, whereas in some patients, extra doses were added when the patient wished to delay surgery as well as the because of surgeon judgment wherein in some patients, we stopped before six doses when we thought adequate bone had formed for intralesional curettage. The mean number of doses was 6.8 per patient (median, 6; range, 3-17) preoperatively. The minimum followup was 12 months (median, 27 months; range, 12-42 months). Every patient showed improvement clinically in terms of pain and halting of tumor progression within three to four doses. This was seen radiologically as a sharply defined soft tissue mass as well as hazy ossification within the tumor. For a case-matched comparison study, we identified controls as 34 patients undergoing curettage from the retrospective analysis of 68 patients curetted without denosumab between February 2010 and July 2016 matched to 25 denosumab-treated patients in terms of site, size, Campanacci grade, and recurrent versus primary status, and with a minimum 2 years followup for the control group. Fisher's exact test was used for statistical study. Patients undergoing resection were planned for surgery after three doses of denosumab to allow the tumor to solidify and potentially decrease tumor spillage at the time of surgery. The resections could not be case-matched for comparison owing to the smaller numbers. RESULTS We observed 14 recurrences out of the 37 curetted tumors (38%). In the case-matched analysis, 11 of 25 patients in the denosumab-treated curettage group had recurrences (44%) compared with seven of 34 (21%) in the nondenosumab-treated control group. The risk of denosumab-treated patients experiencing local recurrence as compared with the nondenosumab-treated patients was nonsignificant with a two-tailed p value of 0.085 (significance at p < 0.05) as derived from Fisher's exact test (odds ratio, 3.03; 95% confidence interval, 0.96-9.54). There was no recurrence in the resection group. Because we do not have a control group for resection, we are unable to comment on the importance of this finding. One major complication that we observed was a recurrence with malignant transformation in a patient with a proximal humeral GCT. We did not observe any other complications related to the denosumab therapy. CONCLUSIONS Although we could not demonstrate a higher risk of local recurrence with preoperative denosumab for intralesional surgery in the dose and frequency we administered, we advise caution in its routine use for intralesional procedures because it may be important to curette up to margins on pretreatment imaging owing to the potential residual tumor within the denosumab-mediated thick bony shell, which may result in local recurrence. We believe that denosumab treatment before resection of a large tumor aids resection without tumor spillage, particularly where important structures like the neurovascular bundle are dissected away from the tumor margin, although we cannot confirm that it helps lower the incidence of recurrence. We are concerned regarding the malignancy-causing potential from our observation in one patient as well as reports of this by others and recommend judicious use of this drug in patients with GCT. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Postmenopausal osteoporosis is associated with microarchitectural deterioration and increased risk of fracture. Osteoporosis therapy effectively reduces the risk of vertebral, nonvertebral, and hip fracture and has been associated with increased survival. Currently approved treatments for osteoporosis include bisphosphonates, denosumab, selective estrogen receptor modulators, and teriparatide. This article reviews the adverse events of therapy associated with these medical interventions. Hormone replacement therapy is not included, because it is no longer indicated for the treatment of osteoporosis in all countries. Calcitonin and strontium ranelate are also not included, because their indication for osteoporosis has recently been limited or withdrawn.

Abstract
Recent clinical studies have suggested that denosumab is associated with beneficial tumour response, surgical down-staging, and reduced surgical morbidity in patients with giant cell tumour of bone. However, these studies reported results of patients still on denosumab treatment, or patients after denosumab treatment but with a short follow-up. Other studies reported that the new osseous tumour matrix and thickened cortical bone that develop with denosumab treatment does not allow the surgeon to delineate the true extent of the tumour, and probably increases the risk for local recurrence. A study showed that cell proliferation is only diminished by denosumab; the cells continue to proliferate in vitro, albeit at a slower rate. More importantly, nine cases of malignant transformation of GCT during denosumab therapy without previous radiation exposure have been reported; inhibition of RANKL may increase the risk of new malignancies due to immunosuppression. With these concerns in mind, this article is an attempt to put essential information in one place, creating a comprehensive review that the curious reader would find interesting and informative.

Abstract
CONTEXT Denosumab, an inhibitor of receptor activator of nuclear factor κ-B ligand, is an approved treatment of giant cell tumor of bone (GCTB) in adults and "skeletally mature" adolescents. Safety concerns include oversuppression of bone remodelling, with risk of osteonecrosis of the jaw (ONJ) and atypical femur fractures during treatment in adults and rebound hypercalcemia after treatment cessation in children. To date, ONJ has never been reported in children or adolescents. OBJECTIVES To describe serious adverse effects during and following high-dose denosumab therapy in GCTB patients. PATIENTS Two adolescents (14 and 15 years) and a young adult (40 years) received fixed-dose denosumab for GCTB for 1.3 to 4 years (cumulative dose, 47 to 98 mg/kg), which was stopped because of development of ONJ in one adolescent and bilateral femoral cortical stress reactions in the young adult. All three patients developed rebound hypercalcemia with acute kidney injury 5.5 to 7 months after denosumab cessation. RESULTS The ONJ necessitated surgical debridement. Rebound hypercalcemia (serum calcium, 3.1 to 4.3 mmol/L) was unresponsive to hyperhydration alone, requiring repeated doses of calcitonin or intravenous bisphosphonate treatment. Hypercalcemia recurred in two patients within 4 weeks, with normal serum calcium profiles thereafter. All patients were naive to chemotherapy, radiotherapy, bisphosphonates, and corticosteroids and were metastases free, confirming the causative role of denosumab in these complications. CONCLUSION These suppression-release effects of high-dose denosumab on bone remodeling raise questions about safety of fixed dosing and treatment duration. In young people, weight-adjusted dosing and safety monitoring during and after antiresorptive therapy is required.

Abstract
Osteoporosis remains a chronic and common disease associated with high medical costs. Pharmacological therapy has shown to be a good strategy to significantly reduce fracture risk. While literary evidence for bone protection in the short and medium term is strongly in it's favor, there are concerns about long-term treatment with antiresorptive drugs. Increased risk of atypical femoral fractures (AFFs) have been demonstrated in several studies following the long-term use of bisphosphonate. Denosumab offers an alternative approach to the treatment of osteoporosis, however, it is also an antiresorptive drug. We present a case of simultaneous bilateral atypical femoral fractures in a patient with denosumab treatment. These findings highlight the need to reevaluate the optimal antiresorptive therapy duration, as well as the safety of transition from bisphosphonates to denosumab and the need for continued monitoring in the prevention of AFFs.

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
BACKGROUND Vertebral fractures (VF) upon Denosumab (DMAB) discontinuation were first described as a distinct phenomenon in 2015, yet the magnitude of this event remains undetermined. OBJECTIVES To estimate fracture risk after DMAB discontinuation, in a real-world setting. METHODS The computerized database of a 2.3-million members' state-mandated health organization was utilized to detect osteoporotic patients with at least two DMAB dispenses. Treatment discontinuation was defined as a refill gap of 3 months or more, while the discontinuation date was defined as an anticipated missed purchase date. Fractures were identified by an osteoporosis registry and individually adjudicated by an expert's review. Fractures occurring within one year from discontinuation among DMAB discontinuers (DD) and from the 2nd year of treatment onwards for persistent users (PU) were included. RESULTS A total of 1500 DD (92% females, mean ± SD age = 71.8 ± 9.5y), and 1610 PU (91%, 71.7 ± 8.8) were identified. At baseline, the groups were comparable in fracture- history, bisphosphonate exposure, smoking, and bone density. Multiple VF occurred in 12 (0.8%) DD vs. 2 (0.1%) PU (p = 0.006). The overall rate of fractures per 100 patient-years of follow-up was significantly higher in DD than PU (RR 3.2, 95% CI 2.2-4.8), as well as the rate of VF (RR 4.7, 95% CI 2.3-9.6) and multiple VF (RR 14.6, 95% CI 3.3-65.3, effect size 1.06). CONCLUSIONS Patients who discontinue DMAB are at greater risk of major OP fractures than those who persist with treatment. Same is true for clinical multiple vertebral fractures, yet the incidence of the latter was low. These findings demonstrate a need for greater awareness and thoughtful management of DMAB discontinuation.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship between type of antiresorptive medication and medication-related osteonecrosis of the jaw (MRONJ) onset and the role of premedication dental evaluation (PMDE) in the prevention of MRONJ. STUDY DESIGN Our database of patients with MRONJ was reviewed. The Kruskal-Wallis test was used to analyze the onset dose of the 3 frequent medication types associated with MRONJ. To evaluate the role of PMDE in the prevention of MRONJ, all patients on antiresorptive and/or antiangiogenic medications seen in the Dental Service of Memorial Sloan Kettering Cancer Center during a 10-year period were subclassified into 2 groups. Group I comprised patients seen for PMDE before the commencement of A/A and group II patients seen after prior exposure to antiresorptive and/or antiangiogenic medications. Fischer's exact test was used to compare the incidence of MRONJ in both groups. RESULTS Patients on denosumab developed MRONJ earlier compared with zoledronate and pamidronate (P = .003). Group I had a significantly reduced incidence of MRONJ (0.9%) compared with group II (10.5%) (P < .0001). Dentoalveolar trauma as a precipitating factor between groups I and II was not statistically significant. CONCLUSIONS Denosumab was associated with an earlier occurrence of MRONJ compared with zoledronate and pamidronate. The role of PMDE may be an effective preventive strategy in reducing the incidence of MRONJ.

Abstract
CONTEXT Fibrous dysplasia/McCune-Albright syndrome (FD/MAS) is a rare bone disorder commonly treated with bisphosphonates, but clinical and biochemical responses may be incomplete. OBJECTIVE To evaluate the efficacy and tolerability of the receptor activator of nuclear factor-κB ligand inhibitor denosumab in the treatment of patients with FD/MAS refractory to bisphosphonate therapy. DESIGN Case series. SETTING Academic center of expertise for rare bone diseases. PATIENTS Data were collected from 12 consecutive patients with FD/MAS with persistent pain and increased biochemical markers of bone turnover (BTMs) after long-term treatment with bisphosphonates (median, 8.8 years) and were treated with subcutaneous denosumab 60 mg at 3- or 6-month intervals with a follow-up for at least 12 months. MAIN OUTCOME(S) Sustained reduction of BTMs and bone pain. RESULTS A 60 mg dose of denosumab once every 3 months, but not once every 6 months, induced a sustained reduction of BTMs. After a median treatment period of 15.5 months (range, 12 to 19) serum alkaline phosphatase activity and propeptide of type 1 procollagen levels were respectively reduced from 212 ± 39.4 IU/L to 79 ± 6.0 IU/L (P = 0.004) and from 346.2 ± 111.1 ng/mL to 55.7 ± 16.6 ng/mL (P = 0.023) and normalized in 70% and 75% of patients, respectively. Although not quantitavely measured, 10 patients reported a reduction in bone pain of whom 6 reported complete elimination of pain. Treatment with denosumab was well tolerated. CONCLUSION Our results indicate that 60 mg of denosumab every 3 months is a promising, well-tolerated treatment of most patients with FD/MAS refractory to bisphosphonate therapy. These results together with those of previously published case reports provide the necessary background for the design of a larger, controlled study.

Abstract
CONTEXT The effects of long-term exposure to denosumab in individuals with renal insufficiency are unknown. OBJECTIVE This post hoc analysis evaluates the long-term safety and efficacy of denosumab in individuals with mild-to-moderate chronic kidney disease (CKD) (stages 2 and 3) using data from the pivotal phase 3, double-blind, 3-year FREEDOM (NCT00089791) and open-label, 7-year extension (NCT00523341) studies. PARTICIPANTS AND METHODS Women age 60 to 90 years with a bone mineral density (BMD) T-score of less than -2.5 to greater than -4.0 at the total hip or lumbar spine were randomly assigned 1:1 to receive denosumab 60 mg subcutaneously every 6 months (long-term arm) or placebo (cross-over arm) in FREEDOM; eligible participants could enroll in the extension to receive denosumab 60 mg subcutaneously every 6 months. Change in estimated glomerular filtration rate (eGFR) from study baseline and annualized rates of fracture and adverse events (AEs) were the main outcome measures. RESULTS Most participants (1259/1969 [64%] long-term arm; 1173/1781 [66%] crossover arm) with baseline CKD stage 2 or 3 remained within the same CKD subgroup at study completion; less than 3% progressed to CKD stage 4. Participants in all eGFR subgroups showed similar, persistent BMD gains over time and a low incidence of fractures. The percentage of participants reporting serious AEs was similar among renal subgroups (normal, CKD stage 2, CKD stage 3a, CKD stage 3b) both for the long-term (54% vs 52% vs 57% vs 58%) and crossover (43% vs 42% vs 43% vs 68%) arms, except CKD stage 3b subgroup, crossover arm. CONCLUSION The safety and efficacy of denosumab did not differ among participants with mild to moderate CKD.

Abstract
CONTEXT Antiresorptive therapy has been associated with osteonecrosis of the jaw (ONJ), an infrequent but potentially serious adverse event. OBJECTIVE To assess information on invasive oral procedures and events (OPEs)-dental implants, tooth extraction, natural tooth loss, scaling/root planing, and jaw surgery-during the 7-year Fracture REduction Evaluation of Denosumab in Osteoporosis every 6 Months (FREEDOM) Extension study and to present details of positively adjudicated ONJ cases. DESIGN Randomized, double-blind, placebo-controlled, 3-year trial (FREEDOM) followed by 7 years of open-label denosumab (FREEDOM Extension). At Extension Year 3, women were asked to record their history of invasive OPEs since the start of the Extension to Year 2.5 and oral events in the prior 6 months. The questionnaire was then administered every 6 months until the end of the Extension. SETTING Multicenter, multinational clinical trial. PATIENTS Postmenopausal women with osteoporosis. INTERVENTIONS Subcutaneous denosumab 60 mg or placebo every 6 months for 3 years, then 7 years of open-label denosumab. MAIN OUTCOME MEASURES Self-reports of OPEs and adjudicated cases of ONJ. RESULTS Of respondents, 45.1% reported at least one invasive OPE. The exposure-adjusted ONJ rate in FREEDOM Extension was 5.2 per 10,000 person-years. ONJ incidence was higher in those reporting an OPE (0.68%) than not (0.05%). CONCLUSIONS Although invasive OPEs were common in these denosumab-treated women and were associated with an increased ONJ incidence, the overall rate of ONJ was low, and all cases with complete follow-up resolved with treatment.
