The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion for three biosimilars:

  • Fresenius Kabi’s Tyenne® (tocilizumab), biosimilar to Roche’s Actemra® / RoActemra®. Tyenne® is intended for the treatment of rheumatoid arthritis, active systemic juvenile idiopathic arthritis, juvenile idiopathic polyarthritis, giant cell arteritis, chimeric antigen receptor T cell-induced cytokine release syndrome, and COVID-19. Tyenne is the first biosimilar for this active substance.
  • Sandoz’s Tyruko® (natalizumab), biosimilar to Biogen’s Tysabri®.  Tyruko® is intended to treat active relapsing remitting multiple sclerosis.
  • BGP Pharma’s Yesafili® (aflibercept), a biosimilar to Regeneron’s Eylea®. It is intended to treat age-related macular degeneration

To obtain approval in Europe, the European Commission needs to approve the above positive recommendations from the CHMP.

During this same July 2023 CHMP meeting, the CHMP also issued a positive opinion for BMS’s Opdivo® (nivolumab) to treat completely resected stage IIB or IIC melanoma and Merck’s Keytruda® (pembrolizumab) to treat HER2-Positive Advanced Gastric or Gastroesophageal Junction.

Amgen filed a motion to intervene in the proceedings on foot between Regeneron and Mylan in West Virginia relating to aflibercept, and has sought to unseal certain documents. Amgen argued that the sealing of the documents blocked the public’s right of access to Court documents, and that the Court has provided no justification for sealing a number of documents.

Regeneron sued Mylan in West Virginia in August 2022, alleging infringement of 24 patents relating to Eylea (including the ‘601 patent), and a 10 day trial has been set down for June 2023, which is 10 months after Regeneron filed its complaint.

A Senju study has shown that its ranibizumab biosimilar (biosim to Roche/Genentech’s Lucentis®) is more cost-effective in treat-and-extend (TAE) regimens compared to aflibercept based on higher quality-adjusted life-years (QALYs) and lower cost in treating neovascular age-related macular degeneration (nAMD).  The biosim was also cost-saving compared to Lucentis® for both TAE and pro re nata regimens. Senju’s ranibizumab biosimilar was the first ranibizumab biosim in Japan, which demonstrated comparable quality, efficacy, and safety for the treatment of nAMD.

Samsung Bioepis filed an IPR petition against Regeneron’s US patent no. 11,253,572directed to methods of treating an angiogenic eye disorder by intravitreal injection of aflibercept via a specified dosage regime, with a specified result.

Apotex (unsuccessfully) filed an IPR against claims 1-14 of the Patent on 10 March 2023, as the PTAB denied institution of Apotex’ petition in March 2023.  Conversely, Samsung is challenging all 30 claims of the Patent.   Samsung argues that a number of the claims are anticipated by press releases and a peer reviewed publication pertaining to phase III clinical trials for aflibercept.  It is also arguing that various claims are invalid for obviousness in light of those disclosures.

This comes only two days after Samsung released its new phase III trial data for its aflibercept (Eylea®) biosimilar.

April 26, 2023

Regeneron listed additional aflibercept patents on the Purple Book patent list.  The Purple Book patent list records the patents exchanged between the originator and biosimilar applicant as part of the patent dance and suggests that another dance has begun with a second biosimilar applicant.

April 19, 2023

The US District Court of West Virginia has issued a claim construction order pertaining to seven claims of the four patents asserted in Regeneron’s BPCIA case against Mylan.  The four patents in suit (US Patent Nos. 10,888,601, 11,084,865, 11,253,572, and 11,104,715) are directed to Regeneron’s Eylea® (aflibercept).  The Court only adopted one of Regeneron’s proposed constructions of the terms, and adopted the remaining six terms as proposed by Mylan.  On 20 April 2023, Mylan sought summary judgment of non-infringement or invalidity of particular claims in the above four patents.  The case is set down for an expedited two-week trial beginning 12 June 2023.

April 14, 2023

The District Court of West Virginia denied Mylan’s emergency motion seeking orders which would require Regeneron to immediately narrow the scope of its infringement proceedings to 12 claims of 3 patents. As it currently stands, Regeneron is required to narrow the scope of the proceedings within seven days of the court making its Markman order, or seven days after the close of fact discovery, whatever is later.  The Court found that Mylan had not shown good cause for an emergency order status or a modification of the scheduling order.

Regeneron sued Mylan in West Virginia in August 2022, alleging infringement of 24 patents relating to Eylea®, and a 10 day trial has been set down for June 2023, which is 10 months after Regeneron filed its complaint.

April 3, 2023

Korea Biomedical Review reported that the 24 week results from Celltrion’s Ph III trials of CT-P42 (aflibercept) demonstrate equivalence and similarity to Regeneron’s Eylea®.  CT-P42 met secondary endpoints of efficacy, safety, and immunogenicity when compared with Regeneron’s Eyela®.  Celltrion intends to file an ABLA for CT-P42 in at least the US and Europe later in 2023.

We have previously reported on the Celltrion IPR challenges to Regeneron’s key aflibercept patents in the US.

March 22, 2023

PTAB instituted Celltrion’s IPR challenges to US 10,888,601 (decision here) and US 10,130,681 (decision here) and Samsung Bioepis’ IPR challenge to US 10,888,601 (decision here).  PTAB also granted Celltrion and Samsung Bioepis’ motions to join these IPRs with the earlier IPRs filed against the same Regeneron patents by Mylan in July 2022 which were instituted in January 2023.  Celltrion and Samsung Bioepis sought to join the Mylan IPRs in February 2023.

Note:

March 13, 2023

PTAB denied institution of the IPR filed by Apotex against Regeneron’s 11,253,572 patent relating to a method of treating an angiogenic eye disorder by administering a VEGF antagonist, including Eylea® (aflibercept).  Apotex filed the IPR in September 2022, challenging claims 1-5, 8-11, 14 and 26 for anticipation and 6, 7, 12 and 13 for obviousness.  PTAB found that Apotex had not demonstrated a reasonable likelihood that it would prevail in showing that any of the challenged claims of the ‘572 patent is unpatentable.

The ‘572 patent is one of the 24 patents included in the Regeneron suit against Mylan in West Virginia, filed in August 2022, and one of the six patents chosen by Regeneron to be determined at a 10 day trial in June 2023, 10 months after Regeneron filed its complaint.  No other application for IPR has been filed to date against the ‘572 patent, although there are currently 7 other applications against 3 patents pending: 10,130,681 (filed by Mylan, Celltrion and Samsung Bioepis), 10,888,601 (filed by Mylan, Celltrion and Samsung Bioepis) and 10,464,992 (filed by Celltrion).  Institution of Mylan’s challenge to 10,857,205 was recently denied after Regeneron disclaimed all claims of the patent. Last year PTAB invalidated Regeneron’s 9,254,338 and 9,669,069 for anticipation based on Mylan’s application for IPR.

In December 2022, we reported on Ontario’s biosimilar switching program which required patients to be transitioned to biosimilars (including infliximab) by 29 December 2023.
