When does a pile of sand become a heap? When is a portfolio of patents too many patents? Can using too many patents to compel generics to take a later entry date turn into monopolistic conduct? These questions lurk the heart of the antitrust litigation brought by buyers of the blockbuster drug, Humira®, against its manufacturer, AbbVie ($ABBV). The case is currently pending within the Northern District of Illinois (In Re: Humira (Adalimumab) Antitrust Litigation, No. 19-cv-1873 (N.D. Ill.)). We previously blogged about related allegations before the case was filed when Boehringer Ingelheim raised them within its biosimilar litigation against AbbVie. On June 8, 2020, the Illinois federal court dismissed the antitrust action pursuant to AbbVie’s motion to dismiss. What are the takeaways from the case?
Read MoreBoehringer Ingelheim has claimed that AbbVie wrongfully created a “patent thicket” around Humira®, and it is delaying biosimilar competition. While that defense is unique, and may be hard to prove on its face, the FDA appears to agree with Boehringer. Did AbbVie create a wrongful “patent thicket” around Humira®?
Read MoreAbbVie ($ABBV) has commenced its latest litigation in its campaign to keep biosimilars for Humira® at bay. On August 10, AbbVie brought suit against Sandoz ($NVS) asserting that two of AbbVie’s patents will be infringed by Sandoz’s proposed biosimilar. Sandoz is the fifth biosimilar to throw its hat in the ring. Does this increase the odds of the US market seeing a biosimilar for Humira® before 2023?
Read MoreThe biosimilars are biting. And they are biting at three big biologics distributed by Roche through its biotech subsidiary, Genentech. Roche currently faces pending biosimilar competition against Avastin® (bevacizumab), Roche’s biggest selling cancer drug, Herceptin® (trastuzmab), Roche’s breast-cancer drug, and Rituxan® (rituximab), Roche’s immunotherapy drug. All three drugs are involved in patent litigations. How long will these cases last? And how long can Roche keep the biosimilars out?
Read MoreThe parties recently filed a report that appears to identify what the September trial will focus on, but it was filed under seal, which leaves investors in the dark.
Read MoreThe much-anticipated trial in the biosimilar litigation over Enbrel® has been pushed from April, to June and now to September. Although Amgen ($AMGN) has asserted five patents against Sandoz’s ($NVS) proposed biosimilar, Erelzi®, the focus of the case are the two Roche patents directed to the entanercept protein itself. And yet, a skirmish has erupted related to one of the three other patents, which collectively cover indications for using entanercept to treat psoriasis indications.
Read MoreThe PTAB has denied institution of two IPRs filed by Coherus Biosciences against patents covering Enbrel®’s proteins, the ‘182 and ‘522 patents. The IPRs were not filed by Sandoz, but they will most likely affect Sandoz. Sandoz already has FDA approval to market Erelzi®, which is its biosimilar for Enbrel®. And Sandoz is going to trial against Amgen in April. How do Coherus IPR decisions affect Sandoz's decision to launch at risk? Or to settle with Amgen?
Read MoreSandoz was denied institution on two IPRs against Humira® patents owned by AbbVie. As we previously discussed, in late 2017, Sandoz filed eight different IPRs against Humira® patents. Two of those IPRs just failed to reach institution. What are the take-aways, for Sandoz and any other Humira® biosimilars?
Read MoreSandoz recently prevailed in court against Amgen by showing it does not infringe a patent covering two of Amgen’s drugs, Neulasta® and Neupogen®. No biosimilar has yet to receive FDA approval for Neulasata® within the U.S. Sandoz recently announced successful Phase 1 data indicating it may be getting closer. Further, other biosimilars for Neulasta® are in the works. Given that Neulasta® accounts for a third of Amgen’s sales, will Amgen’s recent loss in its case against Sandoz read-through to other biosimilars?
Read MoreThe biosimilar statute, Biologics Price Competition and Innovation Act (BPCIA, was passed in 2010. Since then, drug companies have been filing biosimilar applications with FDA. And even though, FDA has approved only nine biosimilar drugs today, an interesting trend may be emerging: biosimilars may be more willing to launch at-risk than small-molecule generics.
Read MoreAmgen’s Enbrel® blockbuster faces encroaching biosimilar competition from Sandoz and Coherus Biosciences. Coherus Biosciences has filed petitions for inter partes review against Amgen’s two protein patents covering Enbrel®, the ‘182 patent and the ‘522 patent. The institution decisions are due before the trial: March 15, 2018 for the ‘182 IPR, and March 13, 2018 for the ‘522 IPR. If the IPRs are instituted, that could shift the dynamics, and push the parties to agree on an entry date. What are Coherus's invalidity arguments?
Read MoreIn February 2016, Amgen brought suit against Sandoz in connection with its proposed biosimilar for Amgen’s Enbrel® blockbuster. The case is on a relatively fast track, currently scheduled to go to trial later this year in April. Some investors have inquired about whether Sandoz has a strong obviousness-type double-patenting invalidity defense for the ‘182 patent.
Read MoreSince the first BPCIA cases hit the courts a few years ago, the Federal Circuit and the Supreme Court have slowly been entangling the knots and confusions around the complicated regulatory scheme. Innovator companies and biosimilars have wrangled over the “patent dance” and the 180-days notice of commercial marketing, including what’s required, what’s not, and who can leverage a regulatory tactical advantage. A case between Amgen and Sandoz has helped resolve many of these issues, and this week, the Federal Circuit took another step towards gutting the statute. What are the take-aways?
