Novartis/Sandoz Biosimilar Erelzi OK'd; Covets Enbrel's US Sales

Novartis AG unit Sandoz Inc. won US approval of its biosimilar Erelzi, which is referenced on Amgen's tumor necrosis factor blocker Enbrel (etanercept). The product, however, currently is caught in a patent dispute, although a recent stipulation has provided some hope for a smoother path through the legal jungle than other biosimilars may face.
