Novartis’ Generic Enbrel Delayed in Patent Fight
Novartis says that its generic version of Amgen’s Enbrel (etanercept) will not go on sale until 2018 at the earliest due to Amgen’s patent protection challenge. FDA has approved Novartis’ biosimilar Erelzi (etanercept-szzs) with an indication for rheumatoid arthritis, plaque psoriasis, ankylosing spondylitis, and other diseases. Amgen is arguing in federal court that its drug has patent protection until 2029, Reuters reports.
Novartis’ Sandoz generics unit and Amgen also are in a court dispute over how quickly companies can begin sales of biosimilar copies. The Supreme Court will hear that case and determine whether companies must wait 180 days after FDA approval before beginning sales of biosimilars.
