Where Amneal stands

Amneal has FDA approval for Prolia, Xgeva and Opsumit, with no US launch confirmed. Of the 70 makers we follow, 25 are lined up to copy more of the drugs on this tracker.

What comes next

Copies with no confirmed US launch, by the earliest year each could reach the market: a settlement date where one is public, otherwise the brand's US exclusivity date. "Now" means that date has passed. Court rulings and new patents can move these.
