- Background
The efficacy and safety of denosumab have been established in a phase 3, randomized, placebo-controlled trial in Korean postmenopausal women with osteoporosis. This postmarketing surveillance study was aimed to investigate the safety and effectiveness of denosumab in Korean real-world clinical practice.
Methods Patients with osteoporosis who had received denosumab per the Korean approved indications in the postmarketing setting between September 2014 and September 2019 were enrolled. The primary endpoint was the incidence of adverse events (AEs) and adverse drug reactions (ADRs). The secondary endpoint was the percent change from baseline in bone mineral density (BMD) of the lumbar spine, total hip, and femoral neck.
Results Of the 3,221 patients enrolled, 3,185 were included in the safety analysis set; 2,973 (93.3%) were female, and the mean± standard deviation (SD) age was 68.9±9.9 years. The mean±SD study period was 350.0±71.4 days. AEs, fatal AEs, and ADRs occurred in 19.3%, 0.8%, and 1.6%, respectively. The most frequent AEs, occurring in >0.5% of patients, were dizziness (0.7%), arthralgia (0.7%), back pain (0.6%), and myalgia (0.6%). Hypocalcemia occurred in 0.3% of patients. There were no cases of osteonecrosis of the jaw and atypical femoral fracture. Mean±SD percent change from baseline in BMD of the lumbar spine, total hip, and femoral neck was 7.3%±23.6%, 3.6%±31.4%, and 3.2%±10.7%, respectively.
Conclusion The safety and effectiveness of denosumab in Korean patients with osteoporosis in this study were comparable with those in the Korean randomized controlled trial, with no new safety findings.

- Background
This phase 3 study evaluated the efficacy and safety of 6-month treatment with romosozumab in Korean postmenopausal women with osteoporosis.
Methods Sixty-seven postmenopausal women with osteoporosis (bone mineral density [BMD] T-scores ≤–2.5 at the lumbar spine, total hip, or femoral neck) were randomized (1:1) to receive monthly subcutaneous injections of romosozumab (210 mg; n=34) or placebo (n=33) for 6 months.
Results At month 6, the difference in the least square (LS) mean percent change from baseline in lumbar spine BMD (primary efficacy endpoint) between the romosozumab (9.5%) and placebo (–0.1%) groups was significant (9.6%; 95% confidence interval, 7.6 to 11.5; P<0.001). The difference in the LS mean percent change from baseline was also significant for total hip and femoral neck BMD (secondary efficacy endpoints). After treatment with romosozumab, the percent change from baseline in procollagen type 1 N-terminal propeptide transiently increased at months 1 and 3, while that in C-terminal telopeptide of type 1 collagen showed a sustained decrease. No events of cancer, hypocalcemia, injection site reaction, positively adjudicated atypical femoral fracture or osteonecrosis of the jaw, or positively adjudicated serious cardiovascular adverse events were observed. At month 9, 17.6% and 2.9% of patients in the romosozumab group developed binding and neutralizing antibodies, respectively.
Conclusion Treatment with romosozumab for 6 months was well tolerated and significantly increased lumbar spine, total hip, and femoral neck BMD compared with placebo in Korean postmenopausal women with osteoporosis (ClinicalTrials.gov identifier NCT02791516).
