January 4, 2024

Accord BioPharma, a wholly-owned subsidiary of Intas Pharmaceuticals, announced that the US Food and Drug Administration (FDA) has accepted its Biologics License Application (BLA) for DMB-3115, its proposed biosimilar to Janssen’s Stelara®.

DMB-3115 was jointly developed by Dong-A St and Meiji Seika Pharma, which granted Intas exclusive licensing rights worldwide excluding certain Asian countries, in an agreement announced in 2021.  Accord BioPharma will be responsible for US commercialisation.

In the same announcement, Accord announced that in October 2023 it reached a settlement with Janssen that would allow Accord to launch DMB-3115 in the US no later than 15 May 2025, pending FDA approval.

Carefirst and another Blue Cross/Blue Shield licensee have brought class action proceedings against Johnson & Johnson (J&J) and Janssen alleging that the companies unlawfully delayed the introduction of biosimilar competition for its Stelara® ustekinumab product onto the US market.  The complaint alleges that J&J would lose exclusivity for Stelara® in the US on 25 September 2023 upon expiration of the relevant composition patent, and that J&J delayed biosimilar competition through a series of unlawful acts to unlawfully prolong patent protection for Stelara® well beyond September 2023.

November 30, 2023

Samsung announced that has signed a settlement and licence agreement with Johnson & Johnson settling all pending US patent litigation between the companies, with a licence to Samsung to commercialise its Stelara (ustekinumab) biosimilar SB17 in the US from 22 February 2025.

Samsung and J&J subsidiary Janssen previously made reference to a settlement (without reference to the licence date) in their joint motion dated 3 August 2023, to terminate Samsung’s Inter Partes Review (IPR) challenging Janssen’s US patent 10 961 307.

Samsung’s BLA for SB17 is under review with the FDA and if approved will be commercialised in the US by Sandoz.

J&J has also entered into ustekinumab settlements with Celltrion (with a US licence date of 7 March 2025), Fresenius Kabi and Formycon (with a US licence date no later than 15 April 2025), Alvotech and Teva (with US licence date no later than 21 February 2025) and Amgen (with a US licence date no later than 1 January 2025).

November 28, 2023

Alvotech reported unaudited financial results for the first nine months of 2023.  Results included product revenue of US$29.8 million in 2023 compared to US$11.1 million for the same period in 2022, and R&D expenses of US$152.8 million compared to US$133.1 million in 2022.  The 2023 revenue consisted of European and Canadian sales of AVT02, Alvotech’s Humira® (adalimumab) biosimilar.

Alvotech also announced that it has resubmitted its BLA for AVT04 Stelara® (ustekinumab) biosimilar, which the FDA has accepted for review with a BsUFA goal date of 16 April 2024.  It also reported highlights including the FDA’s acceptance for review of its resubmitted BLA for AVT02 with a goal date of 24 February 2024, as well as marketing approvals for AVT04 in Canada and Japan, and a positive CHMP opinion in Europe.

November 22, 2023

Biocon Biologics filed an Inter Partes Review (IPR) petition against Janssen’s US patent no. 10,961,307 relating to Stelara® (ustekinumab).  Biocon Biologics is challenging all 34 claims of the patent, relating to methods of treating ulcerative colitis with ustekinumab.

On 9 August 2023, the USPTO Patent Trial and Appeal Board terminated Samsung Bioepis’s IPR challenging the ‘307 patent following Samsung and Janssen’s joint motion for termination on the basis that the parties had resolved the dispute.

October 31, 2023

On 31 October 2023, the FDA approved Amgen’s Wezlana® (ustekinumab-auub), as the first FDA-approved biosimilar to Janssen’s Stelara®Wezlana is approved for the treatment of moderate to severe plaque psoriasis and active psoriatic arthritis (each in both adults and paediatric patients six years and older), and the treatment of moderately to severely active Crohn’s disease and moderately to severely active ulcerative colitis (in adults)Wezlana® is a subcutaneous injection in a 45mg/0.5mL pre-filled syringe and a 45mg/0.5mL vial

October 12, 2023

Alvotech announced that FDA has issued a Complete Response Letter (CRL) regarding its aBLA for AVT04, biosimilar to Janssen’s Stelara® (ustekinumab).  The letter relates to certain deficiencies that were conveyed following the FDA’s inspection of Alvotech’s Reykjavik facility in March 2023.  No other deficiencies were noted by the FDA.  Alvotech intends to resubmit the BLA for AVT04 to the FDA shortly.  This will likely trigger a new BsUFA date for Alvotech’s ustekinumab.

In June 2023 Alvotech and Teva (the exclusive commercialization partner for AVT04 in the US), reached a settlement and license agreement with Johnson & Johnson that grants an entry date for AVT04 in the US no later than 21 February 2025.

On 25 September 2023 Alvotech received approval in Japan for AVT04.

September 19, 2023

Korea Biomed reported that Rani Therapeutics has begun its phase I clinical trial for oral ustekinumab (RT-111) using Celltrion’s CT-P43 (ustekinumab), biosimilar to Janssen’s Stelara®.  Rani will evaluate pharmacokinetics and safety of RT-111 in up to 55 participants.

On 5 June 2023, Rani Therapeutics announced that it has expanded its partnership with Celltrion to develop an orally administered adalimumab biosimilar RT-105, following their previous collaboration on an ustekinumab biosimilar.

August 31, 2023

Alvotech announced in its 2023 Q2 Earnings Presentation that it has resubmitted its interchangeable BLA for AVT02, biosimilar to AbbVie’s high concentration Humira® (adalimumab). The company did not disclose the BsUFA date but anticipated launch in 2024.

The FDA issued a complete response letter (CRL) for Alvotech’s interchangeable BLA on 28 June 2023, noting issues at Alvotech’s facility in Reykjavik, Iceland.

Alvotech also reported that AVT04, its biosimilar to Stelara®, is filed and pending approval in 7 markets including U.S, EU, Japan, and Canada, and it is expecting some approvals to occur before end of 2023.

Alvotech published its financial results on 30 August 2023.

August 25, 2023

Korea Biomedical Review reported that Celltrion has finalised an agreement with Johnson & Johnson (J&J) permitting Celltrion to launch CT-P43, its biosimilar to Stelara®, in the US on 7 March 2025.  Celltrion submitted its aBLA to the FDA in June 2023, and is seeking to obtain marketing authorisation in 2024.

This follows J&J’s ustekinumab settlements with Fresenius Kabi and Formycon (AG) (with a US licensed entry date no later than 15 April 2025), Alvotech and Teva (with a US licensed entry date no later than 21 February 2025), Amgen (with a licensed entry date no later than 1 January 2025) and with Samsung (for an unknown licensed entry date).

Celltrion filed its MAA with the EMA for CT-P43 in May 2023.

August 9, 2023

The USPTO Patent Trial and Appeal Board has terminated Samsung Bioepis’s Inter Partes Review (IPR) challenging Janssen’s US patent 10,961,307 relating to Stelara® (ustekinumab).  The Board’s decision follows Samsung and Janssen’s joint motion, dated 3 August 2023, stating that parties have resolved the dispute and request termination.  The motion states that the parties have entered into  a confidential settlement to resolve all present disputes and to avoid any additional disputes regarding the patent.

Samsung filed the IPR on 21 June 2023, arguing all claims of the patent are invalid, citing (amongst other things) a Janssen clinical overview summary for a phase III clinical trial of ustekinumab.

Samsung also filed a notice of opposition to the grant of an Australian counterpart, AU application no 2019346134, on 12 July 2023.  Law firm Reddie & Grose filed a post-grant notice of opposition (presumed to be on behalf of an unnamed client) to the European counterpart, EP patent no 3883606, on 27 July 2023.

August 7, 2023

Fresenius Kabi and Formycon AG announced they reached a settlement in the US with Johnson & Johnson relating to their ustekinumab (FYB202), biosimilar to Stelara®.  As part of the agreement, Fresenius and Formycon can launch in the US “no later than 15 April 2025”.  There were no proceedings on foot between the parties on foot in relation to FYB202 at the time of the settlement.

On 25 April 2023, Formycon announced the successful conclusion of its extended Phase I clinical study comparing the pharmacokinetics of FYB202 to Stelara®.   Formycon expects to file its BLA for FYB202 with the FDA later in 2023.

This settlement follows Johnson & Johnson’s previous settlement agreements with Amgen (for a licensed entry date no later than 1 January 2024), and with  Alvotech and Teva (for a licensed entry date for AVT04 in the US no later than 21 February 2025).

June 21, 2023

Samsung Bioepis has filed an IPR against Janssen’s US patent no. 10,961,307 (‘307 patent) relating to Stelara® (ustekinumab).  Samsung Bioepis argues that all claims of the ‘307 patent are invalid. Claims 1-4, 6-22, and 24-34 allegedly lack novelty and are anticipated by a Janssen clinical overview summary for a phase III clinical trial of ustekinumab (NCT-236).   All claims (1-34) are allegedly obvious in light of NCT-236 combined with a journal article and the Stelara® Prescribing Information.

On the same day, Samsung Bioepis filed an IPR against Alexion’s US patent no. 10,703,809 (’809 patent) relating to Soliris® (eculizumab).

On 12 June 2023 Alvotech and Teva announced they reached a settlement and licence agreement with J&J for AVT04 (Alvotech’s biosimilar to Stelara®) providing a licensed US launch date of no later than 21 February 2025, and on 22 May 2023 Amgen settled its Stelara® patent invalidity suit with Janssen in the US with a licensed US launch date of no later than 1 January 2025.

June 12, 2023

Alvotech and Teva announced they have reached a settlement and license agreement with Johnson & Johnson for AVT04, Alvotech’s biosimilar to Stelara® (ustekinumab).  J&J have granted a license entry date for AVT04 in the US no later than 21 February 2025. This is seven weeks after the reported date by which Amgen will be able to enter the market (1 January 2025) pursuant to its recent settlement with J&J.

On 6 January 2023, the FDA accepted the BLA for AVT04.

May 24, 2023

As previously reported, on 22 May 2023 the US District Court of Delaware dismissed Janssen’s patent infringement case against Amgen pertaining to its Stelara® (ustekinumab) biosimilar with prejudice on the basis that each party bears its own costs. The proposed orders made it clear that the parties had settled.

Reuters has since reported a statement by Amgen that the ustekinumab settlement will permit Amgen to sell its biosimilar “no later than January 1st, 2025”, suggesting the permitted launch date may be earlier than 1 January 2025.  As the API patent, one of six patents Janssen asserted in the proceedings, expires on 25 September 2023, we speculate that the agreed launch date is some time between 25 September 2023 and 1 January 2025.

May 22, 2023

The US District Court of Delaware has dismissed with prejudice Janssen’s patent infringement case against Amgen pertaining to its Stelara® (ustekinemab) biosimilar.  The parties agreed to dismiss the action with prejudice and each party will bear its own costs, expenses and attorney’s fees, and the proposed orders state the parties have agreed to settle the litigation.

Janssen commenced these proceedings against Amgen in November 2022 in relation to the API and MOT (UC) patents, and filed a motion for preliminary injunction in March 2023 (following dismissal of an earlier application due to non-compliance with the Court’s page limit requirements).

March 6, 2023

Janssen 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.  Janssen 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 Janssen’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. 

March 2, 2023

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.

March 1, 2023

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.”

January 6, 2023

Alvotech and Teva announced that the FDA has accepted for review a BLA for AVT04 (biosimilar ustekinumab). Alvotech reported that it expects the review to be completed in the second half of 2023.  AVT04 is being developed under a strategic agreement between Alvotech and Teva announced in August 2020.


November 30, 2022

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.

August 16, 2022

Formycon has reported that its ustekinumab biosimilar candidate FYB202 showed comparable efficacy and safety to Janssen’s Stelara in a Ph III clinical trial in plaque psoriasis patients.  Formycon’s extended pharmacokinetics Ph I study has commenced.  This follows Formycon’s acquisition of 100% of the rights to FYB202 from Athos, as previously reported.

August 1, 2022

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.
