- Subgroup analysis from Phase 3 study demonstrates consistent efficacy of SB16 across key patient populations
- Results reinforce the totality-of-evidence supporting SB16 biosimilarity
INCHEON, Korea --(BUSINESS WIRE)-- 17.04.2026 --
Samsung Bioepis Co., Ltd. announced today new data supporting consistent efficacy of SB16 (OBODENCE®1), a biosimilar to Prolia2 (denosumab) across patient subgroups compared to the reference denosumab. The data will be presented as a poster presentation at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (WCO-IOF-ESCEO) 2026 in Prague from April 16 to 19.
"Consistent efficacy across patient subgroups is critical in reinforcing physician confidence and advancing treatment accessibility for patients with osteoporosis," said Jeehoon Ghil, Vice President and Medical & Lifecycle Safety Team Leader at Samsung Bioepis. "Such data contribute to the robustness of the overall biosimilarity assessment and support the clinical confidence in our denosumab biosimilar."
SB16 was evaluated in a randomized, double-blind, multicenter Phase 3 clinical trial involving 456 postmenopausal women with osteoporosis, who were assigned to receive either SB16 or reference denosumab3. This subgroup analysis assessed the consistency of treatment effects across key demographic and baseline disease characteristics, including age, body mass index, prior oral bisphosphonate use, smoking status, and presence of vertebral fractures. Efficacy was measured by percent change from baseline in bone mineral density at the lumbar spine, total hip, and femoral neck at month 12. Comparative analyses between treatment groups were conducted using established statistical methods, including analysis of covariance (ANCOVA), to evaluate consistency across subgroups. The results demonstrated that SB16 showed consistent efficacy to reference denosumab across all evaluating subgroups, further supporting the overall biosimilarity of SB16.
