Conexxence (denosumab-bnht) / Fresenius Kabi - LARVOL DELTA

LUMIADE 3: Therapeutic Equivalence of Denosumab Biosimilar FKS518 to Reference Product in Postmenopausal Osteoporosis. (PubMed, J Endocr Soc) - "Immunogenicity was infrequently observed and similar between the FKS518 and the reference denosumab groups. This study demonstrated therapeutic equivalence of, and comparable pharmacokinetics, safety, and immunogenicity profiles between FKS518 and reference denosumab, completing the clinical evidence to propose FKS518 as a biosimilar to denosumab."

Analysing the Economic Impact of Denosumab in the Treatment of Osteoporosis (EULAR 2025) - "Published literature indicated reference product denosumab is generally cost-effective despite its high cost, owing to offsets from reductions in fracture-related treatment costs or QALY gains. However, affordability issues remain in regions with lower WTP thresholds. Further studies should be conducted to examine and quantify the impact of biosimilars which may help to mitigate the unmet needs in this therapeutic area."

A double-blind, randomized, two-arm, single-dose, parallel-group study in healthy participants to compare the pharmacokinetics, pharmacodynamics, and immunogenicity of FKS518 proposed biosimilar to denosumab with the originator (LUMIADE-1 study). (ASCO 2024) - "PK equivalence of FKS518 and denosumab originator product was demonstrated with similar PD, safety and immunogenicity profile for the two products. This study adds to the totality of evidence supporting FKS518 as a proposed biosimilar to denosumab."
