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
Recently, the Federal Circuit Court of Appeals dismissed Pfizer Inc.’s (“Pfizer”) appeal for lack of Article III standing. Pfizer had filed an inter partes review (“IPR”) against Chugai Pharmaceutical Co. (“Chugai”) arguing that U.S. Patent Nos. 7,332,289 and 7,927,815 (“the patents-at-issue”) were unpatentable. The patents at issue are directed towards methods of manufacturing rituximab. Specifically,
We previously wrote about Genentech’s U.S. Patent No. 6,407,213 (“the ’213 patent”) to Carter, first in October 2017, and more recently in March 2018. At the time of our last update, the ’213 patent had been at issue in six district court litigations, and had been the subject of ten filed IPR petitions,
As we previously reported, one of three Pfizer IPR petitions filed in April 2017 against Biogen-owned patents claiming methods of treatment with rituximab was instituted. The instituted IPR is IPR2017-01168 regarding U.S. Patent No. 8,821,873 (the “’873 patent”), and the PTAB recently issued its Final Written Decision.
Adhering to its institution decision where it
Recently, Pfizer was denied institution of two follow-on inter partes review (IPR) petitions, IPR Nos. 2018-00330 and 2018-00331 (“the 2018 petitions”), filed on December 18, 2017, asserting invalidity of Genentech patents, U.S. 6,339,142 (“the ’142 patent”) and U.S. 9,249,218 (“the ’218 patent”). The Patent Trial and Appeal Board (“the Board”) denied instituting the IPRs using
The PTAB recently instituted a second IPR of US Patent 9,296,821 (“the ’821 patent”), which covers certain uses of Rituxan® (rituximab), a monoclonal antibody marketed by Genentech and Biogen Pharmaceuticals. The ‘821 patent claims methods of treating low grade or follicular non-Hodgkin’s lymphoma (NHL) by administering rituximab during a chemotherapeutic regimen of cyclophosphamide, vincristine, and
U.S. Patent No. 8,329,172 (“the ’172 patent”), a Biogen-owned patent covering a treatment regime for low-grade B-cell non-Hodgkin’s lymphoma, has been a relatively frequent subject of our posts. We first wrote about it in March of 2017, reporting on the filing of Celltrion’s IPR petition against the patent, then again that May, reporting
As we recently covered, May 15, 2018, saw the FDA granting approval to Hospira (now a Pfizer subsidiary) for its Retacrit injection, a biosimilar to Amgen’s Epogen®. The approval, based on a Biologics License Application dated December 16, 2014, came after Hospira resubmitted its application twice after receiving Complete Response Letters from the FDA,
Earlier this month, Celltrion, Inc. (“Celltrion”) filed a copycat IPR petition directed against U.S. Patent No. 7,976,838 (“the ʼ838 patent”) that is essentially identical to a petition filed by Pfizer, Inc. (“Pfizer”). The PTAB recently instituted review of the ʼ838 patent based on Pfizer’s petition in IPR2017-01923. Celltrion’s copycat petition was accompanied by a motion
Today, the FDA announced that it approved Retacrit (epoetin alfa-epbx) as a biosimilar to Epogen® for the treatment of anemia caused by chronic kidney disease, chemotherapy, or use of zidovudine in patients with HIV infection. The FDA also approved Retacrit for use before and after surgery to reduce the chance that red blood cell transfusions
