Comparative Study Meta-Analysis
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.

Randomized Controlled Trial
Romosozumab is a bone-forming agent with a dual effect of increasing bone formation and decreasing bone resorption. In FRActure study in postmenopausal woMen with ostEoporosis (FRAME), postmenopausal women with osteoporosis received romosozumab 210 mg s.c. or placebo once monthly for 12 months, followed by denosumab 60 mg s.c. once every 6 months in both groups for 12 months. One year of romosozumab increased spine and hip BMD by 13% and 7%, respectively, and reduced vertebral and clinical fractures with persistent fracture risk reduction upon transition to denosumab over 24 months. Here, we further characterize the BMD gains with romosozumab by quantifying the percentages of patients who responded at varying magnitudes; report the mean T-score changes from baseline over the 2-year study and contrast these results with the long-term BMD gains seen with denosumab during Fracture REduction Evaluation of Denosumab in Osteoporosis every 6 Months (FREEDOM) and its Extension studies; and assess fracture incidence rates in year 2, when all patients received denosumab. Among 7180 patients (n = 3591 placebo, n = 3589 romosozumab), most romosozumab-treated patients experienced ≥3% gains in BMD from baseline at month 12 (spine, 96%; hip, 78%) compared with placebo (spine, 22%; hip, 16%). For romosozumab patients, mean absolute T-score increases at the spine and hip were 0.88 and 0.32, respectively, at 12 months (placebo: 0.03 and 0.01) and 1.11 and 0.45 at 24 months (placebo-to-denosumab: 0.38 and 0.17), with the 2-year gains approximating the effect of 7 years of continuous denosumab administration. Patients receiving romosozumab versus placebo in year 1 had significantly fewer vertebral fractures in year 2 (81% relative reduction; p < 0.001), with fewer fractures consistently observed across other fracture categories. The data support the clinical benefit of rebuilding the skeletal foundation with romosozumab before transitioning to antiresorptive therapy. © 2018 The Authors.

Randomized Controlled Trial
Increased bone turnover and rapid bone loss follow discontinuation of denosumab. We investigated the long-term efficacy of zoledronate (ZOL) in maintaining bone mineral density (BMD) after discontinuation of denosumab. In this randomized, open-label, interventional study, we included 61 postmenopausal women and men older than 50 years discontinuing denosumab after 4.6 ± 1.6 years. We administered ZOL 6 months (6 M) or 9 months (9 M) after the last denosumab or when bone turnover had increased (observation group [OBS]). ZOL was readministrated if p-cross-linked C-terminal telopeptide (p-CTX) increased ≥1.26 μg/L or BMD decreased ≥5%. The results after 12 months have previously been published; here we report the outcome after 24 months (ClinicalTrials NCT03087851). Fifty-eight patients completed the study. From 12 to 24 months after the initial ZOL, lumbar spine (LS) BMD was maintained: 0.9 ± 0.9%, 0.4 ± 0.8%, and 0.3 ± 0.7% in the 6 M, 9 M, and OBS groups, respectively (p > .05, no between-group differences). Similarly, total hip (TH) and femoral neck (FN) BMD did not change in any group during year 2. From baseline to 24 months after ZOL, LS BMD decreased by 4.0 ± 0.8%, 4.1 ± 0.8%, and 4.3 ± 1.5% in the 6 M, 9 M, and OBS groups, respectively (p < .001, no between-group differences). Significant bone loss (LS, TH, or FN) was found in all groups 24 months after ZOL: 6 M group: n = 12 (60%), 9 M group: n = 7 (37%), and OBS group: n = 10 (53%). P-CTX did not change significantly during the second year (p > .05, no between-group differences). No patient fulfilled the CTX or fracture criteria for retreatment during year 2; however, 9 patients were retreated at M24 due to BMD loss ≥5%. Two patients sustained a non-vertebral fracture during year 2. Treatment with ZOL subsequent to long-term denosumab did not fully prevent increased bone turnover and bone loss during the first year; however, CTX remained with the reference range and BMD was maintained during the second year. © 2021 American Society for Bone and Mineral Research (ASBMR).

Meta-Analysis
BACKGROUND
The aim of the present study was to analyse the incidence, risk ratio (RR) and prognoses of two types of medication-related osteonecrosis of the jaws (MRONJ): denosumab-related osteonecrosis of the jaws (DRONJ) and Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ) in cancer patients under treatment with denosumab or zoledronic acid (ZA).
MATERIAL AND METHODS
An electronic and manual search was conducted for randomized controlled trials (RCTs) until May 2019. Assessment of the identified studies, risk of bias and data extraction were performed independently by two reviewers. The incidence of DRONJ and BRONJ and the RR to develop MRONJ were calculated at 1 year, 2 years and 3 years of exposure. It was also calculated the odds ratio (OR) of their respective prognoses. They were calculated normalizing the values of the individual studies to 1 year, 2 years or 3 years when necessary through robust regression models using a statistical program.
RESULTS
From 1.277 references identified, 8 RCTs were included, which comprised a total of 13.857 patients with a variety of neoplasms. The incidence of DRONJ in cancer patients under treatment with denosumab ranged from 0.5 to 2.1% after 1 year, 1.1 to 3.0% after 2 years, and 1.3 to 3.2% after 3 years of exposure. The incidence of BRONJ in cancer patients under treatment with ZA ranged from 0.4 to 1.6% after 1 year of exposure, 0.8 to 2.1% after 2 years, and 1.0 to 2.3% after 3 years of exposure. Statistically significant differences were found between denosumab and ZA in the risk of developing MRONJ after 1, 2 and 3 years of exposure. Nevertheless, there were no significant differences in terms of patient prognosis.
CONCLUSIONS
Denosumab is associated with a significantly higher risk of developing MRONJ compared to ZA. Nevertheless, no differences were found in its prognoses.

Randomized Controlled Trial
Denosumab reduces bone resorption and vertebral and nonvertebral fracture risk. Denosumab discontinuation increases bone turnover markers 3 months after a scheduled dose is omitted, reaching above-baseline levels by 6 months, and decreases bone mineral density (BMD) to baseline levels by 12 months. We analyzed the risk of new or worsening vertebral fractures, especially multiple vertebral fractures, in participants who discontinued denosumab during the FREEDOM study or its Extension. Participants received ≥2 doses of denosumab or placebo Q6M, discontinued treatment, and stayed in the study ≥7 months after the last dose. Of 1001 participants who discontinued denosumab during FREEDOM or Extension, the vertebral fracture rate increased from 1.2 per 100 participant-years during the on-treatment period to 7.1, similar to participants who received and then discontinued placebo (n = 470; 8.5 per 100 participant-years). Among participants with ≥1 off-treatment vertebral fracture, the proportion with multiple (>1) was larger among those who discontinued denosumab (60.7%) than placebo (38.7%; p = 0.049), corresponding to a 3.4% and 2.2% risk of multiple vertebral fractures, respectively. The odds (95% confidence interval) of developing multiple vertebral fractures after stopping denosumab were 3.9 (2.1-7. 2) times higher in those with prior vertebral fractures, sustained before or during treatment, than those without, and 1.6 (1.3-1.9) times higher with each additional year of off-treatment follow-up; among participants with available off-treatment total hip (TH) BMD measurements, the odds were 1.2 (1.1-1.3) times higher per 1% annualized TH BMD loss. The rates (per 100 participant-years) of nonvertebral fractures during the off-treatment period were similar (2.8, denosumab; 3.8, placebo). The vertebral fracture rate increased upon denosumab discontinuation to the level observed in untreated participants. A majority of participants who sustained a vertebral fracture after discontinuing denosumab had multiple vertebral fractures, with greatest risk in participants with a prior vertebral fracture. Therefore, patients who discontinue denosumab should rapidly transition to an alternative antiresorptive treatment.
