Jannsen Biotech, Inc. has filed another motion for a preliminary injunction against Amgen regarding its ustekinemab biosimilar, after its original motion was denied by US District Court Judge Noreika on 2 March 2023.  Jannsen is seeking to enjoin Amgen, Inc. from manufacturing and using in commercial quantities, offering to sell, selling within the United States, or importing for commercial purposes into the United States its ABP 654 biosimilar product. 

As we previously reported, Judge Noreika had denied Jannsen’s motion because it did not comply with the court’s page limit requirements.  Her Honour orally ordered that the motion could be re-filed in compliance with court requirements.

Janssen announced its positive long-term safety and clinical data for Stelara® (ustekinumab) in Chron’s disease and ulcerative colitis (five and four years respectively) at the ECCO Congress.  The findings indicate that key safety events were similar between a placebo and Stelara®.  The data demonstrated that of the patients with moderate to severe ulcerative colitis who achieved clinical response and continued treatment with Stelara® for 200 weeks – 58% were in clinical remission and 80% were in clinical response.

On Thursday, US District Court Judge Noreika denied a motion filed by Janssen Biotech, Inc (a Johnson & Johnson subsdiary) for a preliminary injunction regarding Amgen’s ustekinemab biosimilar, because the motion did not comply with the court’s page limit requirements.  We previously reported that Janssen commenced proceedings against Amgen in the US District Court (District of Delaware) in November 2022, asserting infringement of two patents, US 6902734 (ustekinemab compound) and US 10961307 (use of ustekinemab for the treatment of ulcerative colitis).   Judge Noreika ordered that the motion may be refiled in compliance with court requirements, so the consequences of the denial may be short-lived.   Janssen’s original Complaint states that Amgen had notified Janssen of its intention to commence marketing its Stelara® biosimilar on 6 May 2023 or as soon as it received FDA approval thereafter.

Alvotech announced its full financial results for 2022, highlighting its annual revenue increased by 114% to USD$85M, primarily driven by the commercialisation of AVT02 (adalimumab), biosimilar to AbbVie’s Humira® in 17 countries.  As of December 31, 2022, the company had cash and cash equivalents of US$66.4 million, and R&D expenses were US$180.6 million.  In addition, Alvotech highlighted recent corporate achievements, including its marketing applications for AVT04  (ustekinumab), a proposed biosimilar to Johnson & Johnson’s Stelara® in the US (FDA accepted BLA for review in January 2023 with a new goal date of 13 April 2023), and EU (expected EMA recommendation in the second half of 2023).

The company held a business update conference with the investment community on 2 March 2022.

Robert Wessman, Chairman and CEO of Alvotech said that “Looking ahead, 2023 is expected to be equally important.  We’re currently preparing for a reinspection of our Reykjavik facility by the FDA, which, if satisfactory, could pave the way for the approval and subsequent launch of our interchangeable, high concentration biosimilar to Humira® in the US market on July 1, 2023.”

Janssen sued Amgen in the District Court of Delaware in relation to Amgen’s ABP654 (biosimilar ustekinumab).  Janssen alleges that Amgen’s product will infringe US patent Nos 6,902,734 (API) and 10,961,307 (methods of treating ulcerative colitis).  Amgen released preliminary results from its Ph III trials of ABP654 in April 2022, and it has not yet been approved by the FDA.

The Australian Pharmaceutical Benefits Advisory Counsel (PBAC) published the public summary documents from its July 2022 meeting.  Among the updates were:

• Yuflyma® (adalimumab): recommended with ‘a-flagged’ status for the same indications as Humira®.
• Tysabri® (natalizumab): amended listings (removing a requirement for neurologists prescribing natalizumab to be registered with the Tysabri Australian Prescribing Program) recommended by PBAC.
• Epidyolex® (cannabidiol): not recommended for the treatment of Lennox-Gastaut syndrome, as the incremental cost effectiveness ratio was deemed to be unacceptably high at the price proposed.
• Keytruda® (pembrolizumab): amended listings (increasing the max number of repeats, and maximum number of cycles in a lifetime) recommended by PBAC.
• Stelara® (ustekinumab): vial for IV infusion and PFS recommended for the treatment of moderate to severe ulcerative colitis. 90mg/1mL PFS recommended for the treatment of Crohn disease and severe chronic plaque psoriasis.

BioFactura has announced successful completion of its Ph I trials relating to biosimilar ustekinumab candidate BFI-751.  The trial in Australia and New Zealand involved 226 subjects and demonstrated bioequivalence of BFI-751 to the US and EU versions of Janssen’s Stelara.  BioFactura now intends to conduct a Ph III confirmatory safety and efficacy trial in patients.

Janssen announced that the FDA has approved Stelara® (ustekinumab) for the treatment of paediatric patients aged six and over with active psoriatic arthritis (PsA).  As there were insufficient paediatric patients with PsA to conduct clinical trials, the FDA based its approval on phase III trials in adults and children with plaque psoriasis and adults with PsA.

Formycon published its Q1 2022 financial results, reporting sales and other earnings of EUR 8.2 million.  Formycon also announced the addition of two biosimilar projects to its pipeline, FYB208 and FYB209, for undisclosed products.  Late stage Formycon development programs include biosimilars to Lucentis® (ranibizumab), Stelara® (ustekinumab) and Eylea® (aflibercept). Formycon plans to launch its biosimilar to Lucentis® (ranibizumab) in the second half of 2022.

Janssen announced data from two new analyses of Stelara® (ustekinumab) for the treatment of adults with Crohn’s disease and ulcerative colitis. Janssen reported that the data from these analyses provides additional support for Stelara® as a first-line option for Crohn’s disease and ulcerative colitis.

Australia’s PBAC recommended the listing of Amgen’s Mvasi® (biosimilar bevacizumab). The PBAC also recommended listing Keytruda® (pembrolizumab) for the first line treatment of unresectable or metastatic mismatch repair deficient colorectal cancer and recommended listing Stelara® (ustekinumab) for the treatment of paediatric patients with severe chronic plaque psoriasis.

These increases have come at a cost to AbbVie, with use of Humira® in UC and CD decreasing in the EU.
