As previously reported, the FDA had yet to approve any biosimilars in 2020 as of June 9, despite a growing pipeline. Since then, the FDA has approved two biosimilar products.

On June 11, Pfizer Inc. announced the FDA’s approval of Nyvepria™ (pegfilgrastim-apgf), a biosimilar of Amgen’s Neulasta™. Nyvepria is indicated “to decrease the incidence of

On January 15, 2020, Hospira filed a petition for rehearing en banc asking the full Federal Circuit to reconsider a prior panel’s analysis of the Safe Harbor provision and reverse the finding of infringement. In December 2019, the Federal Circuit affirmed the District of Delaware’s decision denying Hospira’s motion for judgment as a matter of

As we previously reported, earlier this year the Federal Circuit affirmed a district court’s finding that Sandoz’s ZARXIO filgrastim biosimilar and proposed pegfilgrastim biosimilar do not infringe Amgen’s patents. The patents-at-issue were Amgen’s U.S. Patent Nos. 8,940,878 (“the ’878 patent”) and 6,162,427 (“the ’427 patent”). The ’872 patent is directed towards methods of purifying

In a recent precedential opinion[1], the Federal Circuit rejected arguments by Amgen that a single step purification process used by Sandoz for its G-CSF biosimilar infringed claims of Amgen’s patent describing a multistep purification procedure for proteins expressed in a non-mammalian system.

In this case, the Federal Circuit explained that the doctrine of

On April 25, 2019, the U.S. Food and Drug Administration (“FDA”) approved new biosimilar product EticovoTM (etanercept-ykro) by Samsung Bioepis.  Eticovo is a biosimilar to Enbrel® (etanercept), which is marketed by Amgen, Inc. (“Amgen”).  Like Enbrel, Eticovo was approved across five eligible indications for the treatment of rheumatoid arthritis, ankylosing spondylitis, plaque psoriasis, psoriatic

Recently, in Adello Biologics LLC v. Amgen Inc., Case PGR2019-00001 (Paper No. 13) (PTAB Apr. 19, 2019), the PTAB instituted post-grant review of claims 1-30 of U.S. Patent No. 9,856,287 (“the ’287 patent”).  The ’287 patent is the patent at issue in a pending litigation between Amgen and Apotex under the Biologics Price Competition

Over four years ago, in October 2014, Amgen initiated a patent infringement suit against Sanofi and Regeneron regarding biologics for treatment of high cholesterol.[1]  The case reached an important milestone recently as a jury entered a verdict largely upholding the validity of Amgen’s asserted patents, to the disappointment of Sanofi and Regeneron.  A similar

On February 21, 2019, Sandoz Inc. (“Sandoz”) filed suit against Amgen Inc. and Amgen Manufacturing Limited (collectively “Amgen”) seeking declaratory judgment of non-infringement and invalidity of Amgen’s U.S. Patent No. 9,643,997 (“the ʼ997 patent”). The ʼ997 patent is directed to methods of purifying a protein expressed in a non-native limited solubility form in a non-mammalian

Earlier this month, Amgen initiated suit against Apotex in the Middle District of Florida, alleging infringement of U.S. Patent No. 9,856,287 (“the ’287 patent”). This is the third complaint that Amgen has brought against Apotex under the Biologics Price Competition and Innovation Act (the “BPCIA”), based on Apotex’s abbreviated biologic license applications (“aBLAs”) for biosimilars
