Samsung Bioepis’ first endocrinology biosimilar to be approved by the FDA – widening its therapeutic areas and portfolios
OSPOMYV, referencing Prolia, has been approved for the treatment of postmenopausal women with osteoporosis at high risk for fracture, treatment to increase bone mass in men with osteoporosis at high risk for fracture, treatment of glucocorticoid-induced osteoporosis in men and women at high risk for fracture, treatment to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer and for the treatment to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer.
XBRYK, referencing Xgeva,has been approved for the prevention of skeletal-related events in patients with multiple myeloma and in patients with bone metastases from solid tumors, treatment of adults and skeletally mature adolescents with giant cell tumor of bone that is unresectable or where surgical resection is likely to result in severe morbidity, and for the treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.

“The FDA approval of OSPOMYV and XBRYK marks a key step in improving patient access and alleviating treatment cost for patients with osteoporosis and cancer-related bone loss in the US. By providing quality-proven biosimilars, we are helping to address a critical healthcare need and reduce the burden of skeletal fractures that impact patients’ quality of life,” said Byoungin Jung, Vice President and Regulatory Affairs Team Leader at Samsung Bioepis. “This achievement underscores our commitment to healthcare innovation through biosimilars and our mission to meet the growing needs in critical therapeutic areas.”
The FDA approval was based on totality of evidence including analytical, non-clinical data, and clinical data. A randomized, double-blind, three-arm, parallel group, single-dose Phase 1 study demonstrated the pharmacokinetic (PK) equivalence between SB16, EU-sourced denosumab (EU-DEN), and US-sourced denosumab (US-DEN) in healthy male participants. The primary PK endpoints were met, in terms of area under the concentration-time curve (AUC) from time zero to infinity, AUC from time zero to the last quantifiable concentration, and maximum serum concentration.1 In addition, a randomized, double-blind, multi-center Phase 3 study demonstrated equivalent efficacy and comparable safety, immunogenicity, PK, and pharmacodynamics (PD) profiles between SB16 and reference denosumab (DEN) in postmenopausal osteoporosis (PMO) patients. The primary endpoint was met in terms of percent (%) change from baseline in lumbar spine bone mineral density (BMD) at Month 12, and a follow-up up to Month 18 demonstrated switching to SB16 from DEN were comparable up to Month 18 in terms of efficacy, PK, PD, safety and immunogenicity.2,3
OSPOMYV and XBRYK, marks Samsung Bioepis’ 9th and 10th FDA approved medicines as well as the company’s first FDA approval for an endocrinology biosimilar, setting another milestone for the company to broaden its biosimilar portfolio that cover a spectrum of therapeutic areas including immunology, oncology, ophthalmology, hematology and endocrinology.
