Investigators presented two studies on Monday at the American Society of Hematology Annual Meeting and Exposition (ASH) showing the potential for significant cost-savings by switching to biosimilar pegfilgrastim from the pegfilgrastim on-body injector (PEG-OBI). In one study, investigators demonstrated a potential for savings from a conversion to several biosimilar filgrastim…

Amgen is asserting the ’878 and…
This morning, the Federal Circuit issued a precedential opinion affirming the district court’s judgment of non-infringement in favor of Sandoz in its BPCIA litigation against Amgen concerning Sandoz’s Zarxio® (filgrastim-sndz) biosimilar product and proposed pegfilgrastim biosimilar.

U.S. Patent No. 9,856,287, which is directed to a protein refolding method, is one of the patents-in-suit in the pending Amgen v. Adello (filgrastim) BPCIA litigation and the sole patent-in-suit in the pending Amgen v. Apotex (filgrastim and pegfilgrastim) BPCIA litigation. As we previously reported, in November 2018, Adello and…
On February 21, 2019, Sandoz initiated a lawsuit against Amgen in the Northern District of California seeking a declaration that its biosimilar filgrastim and pegfilgrastim products do not infringe the Amgen’s ’997 patent.

Last October, we reported that Taiwan-based Tanvex BioPharma (“Tanvex”) announced that it had submitted a BLA to the FDA seeking approval of TX-01, a proposed biosimilar referencing Neupogen® (filgrastim) indicated for chemotherapy induced neutropenia. Last November, the FDA accepted Tanvex’s BLA for its filgrastim biosimilar. This week Tanvex has submitted a New Drug Submission (NDS) to…
As we previously reported, the district court granted Sandoz’s motion for summary judgment of non-infringement in the ongoing Amgen v.
