Below we provide updates in three pending litigations. First, in an update on the Amgen v. Coherus appeal regarding Coherus’s biosimilar application for pegfilgrastim, Amgen filed its opening brief on August 20. Amgen’s statement of the issues reads: 1. Whether the district court erred in dismissing Amgen’s Complaint, with prejudice, based…
Yesterday, September 4, 2018, Genentech filed a complaint against Samsung Bioepis in the District of Delaware alleging infringement under the BPCIA of 21 patents based on Bioepis’s filing of an aBLA for SB3, a biosimilar candidate referencing Herceptin® (trastuzumab). This is the fourth litigation regarding a biosimilar of Herceptin®, following…
On Wednesday, Celltrion announced its completion of its Phase 3 clinical trial for Remsima SC, a subcutaneous version of its biosimilar Remsima® (infliximab). According to Celltrion, “[t]he subcutaneous formulation allows patients to conveniently inject it by themselves according to the administration cycle unlike the intravenous formulation that require patients to…
Following up on our previous coverage of Immunex’s patent infringement suit against Sanofi related to Immunex’s Dupixent® (dupilumab) biologic, Judge Otero recently denied Sanofi’s motion for summary judgement of invalidity based on indefiniteness of the claim terms “competes” and “binding affinity (Ka).” Sanofi criticized Immunex’s ’487 patent for failing to…
On August 22, 2018, Pfizer submitted a citizen petition to the Food and Drug Administration requesting “guidance clarifying appropriate sponsor communications about the nature and properties of biosimilar products.” Specifically, Pfizer petitioned FDA to clarify what constitutes a false and misleading communication with respect to the safety and effectiveness of biosimilars relative…
As we have previously covered, last month the court in Janssen v. Celltrion (D. Mass., J. Wolf) issued a memorandum opinion granting Celltrion’s motion for summary judgment of non-infringement of the sole remaining patent-in-suit, and the next day entered final judgment for Celltrion. The court subsequently entered an amended final judgment to dismiss without prejudice Celltrion’s…
As we previously reported, last September a District of Delaware jury issued a verdict that Hospira’s manufacture of 14 batches of drug substance in connection with its proposed biosimilar of Amgen’s Epogen® (epoetin alfa) was not protected activity under the § 271(e)(1) safe harbor and infringed Amgen’s ’298 patent, and…
As we reported here, Momenta is appealing a PTAB decision upholding the patentability of BMS’s U.S. Patent No. 8,476,239 (“the ’239 patent”), which relate to BMS’s Orencia® (abatacept) product. Momenta has not yet filed an aBLA for its abatacept biosimilar candidate, M834, so one of the key issues on appeal is whether Momenta has Article III standing…
As we previously reported, Sandoz appealed the PTAB’s decision not to institute an IPR regarding AbbVie’s U.S. Patent No. 9,512,216, which relates to a method for treating moderate to severe chronic plaque psoriasis using adalimumab. Last month, the Federal Circuit ordered Sandoz to show cause why the appeals should not be dismissed for lack…
As we previously reported, a panel of the Federal Circuit in St. Regis Mohawk Tribe v. Mylan held that “tribal immunity cannot be asserted in IPRs.” The Federal Circuit’s decision, if upheld, means that Allergan’s sale and license-back of patents covering its branded product Restasis to the Tribe was ineffective in shielding the…
