The denosumab biosimilar is approved for all indications of the reference product Xgeva (denosumab).

The FDA also approved Conexxence (denosumab-bnht), a biosimilar referencing Prolia (denosumab).

In addition, Fresenius’ operating company has reached a Global Settlement with Amgen concerning its denosumab biosimilars.
