UPDATE – New Zealand Intends to Allow Advertising of Unapproved Drugs at Medical Professional Conferences

UPDATE: New Zealand intends to allow advertising of unapproved drugs at medical professional conferences…soon?

We have previously reported, twice, on the New Zealand government’s policy to allow the advertisement at medical conferences and trade shows of medicines not approved by the New Zealand medicines regulator, Medsafe.  In our first report, we noted that although the policy was being presented as early as July 2025 as an existing or imminent law change, the required statutory amendments had not been made or even publicly presented in draft.  Our subsequent update then reported on the Ministry of Health’s indication that this reform would be included in the Medical Products Bill, intended to come into force in 2030 and replace the Medicines Act 1981.  Based on the Ministry’s indication, we considered that the advertising reform would not become part of the current Medicines Amendment Bill, then awaiting its second reading in Parliament.  The government has now changed its mind about this and has moved an Amendment Paper to include the advertising reforms in the current, previously unrelated, Medicines Amendment Bill.

The Medicines Amendment Bill was debated in parliament on 21 October 2025 and passed the second of the three readings needed to become law.  The Minister of Regulation (who is also the Associate Minister of Health) announced, when moving the second reading, that an Amendment Paper would be introduced to add the advertising reforms to the Bill before its consideration by parliament ahead of its third and final reading.  The Amendment Paper was subsequently published on 31 October 2025.

Opposition members speaking on the Bill were taken by surprise (as were we!) by the announcement, which they criticised for coming after public submissions had been taken and the Parliamentary Health Committee had considered and reported back on the Bill.  It has not been explained why advertising reform, which has been policy since at least April 2025, was not already included in the Bill which was introduced to parliament on 31 March 2025.  The opposition members have indicated that the further amendments will be carefully scrutinised.

The original provisions of the Amendment Bill appear to have broad, cross-party support and are likely to pass.  Those are to:

  • introduce a fast-track approval process for drugs already approved in two, recognised, foreign jurisdictions
  • broaden some prescription powers.

The new Amendment Paper proposes inserting into the Medicines Act 1981 an exemption from the prohibition on advertising unapproved medicines for a person who “advertises at [a] medical conference the availability of the medicines.”  Any such advertising will remain subject to the restrictions and requirements of Part 4 of the Medicines Act, and Part 3 of the Medicines Regulations 1984.

As drafted, the proposed exemption will apply to a wider audience than other, current exemptions to restrictions on the advertising of approved medicines to health professionals.  The Amendment Paper defines “medical conference” to include any conference or associated trade show where the intended audience are “health practitioners regulated under the Health Practitioners Competence Assurance Act 2003.”  As well as doctors, dentists, midwives, nurses and pharmacists, this includes chiropractors, dieticians, occupational therapists, osteopaths, physiotherapists, podiatrists and others.  This can be contrasted with the narrower audience classes referred to in:

  • section 60 of the Medicines Act, “Exemption for certain advertisements”, which applies to advertising to a medical practitioner, dentist, nurse, pharmacist, or any other person qualified to provide therapeutic treatment in the course of a profession or occupation and registered under any enactment as a person so qualified; and
  • regulation 11 of the Medicines Regulations 1984, “Advertisements Intended for Health Professions”, which refers to the “medical, dental, pharmaceutical, and related professions”,

Other bodies which provide guidance relating to the advertising of medicines in New Zealand may update their publications to be consistent with any law change, for example:

We expect that the Amendment Paper will come under scrutiny by opposition parties in the parliamentary debate on the Bill, scheduled for this week.  We will report further on this and any other developments.  Until then, the key points to remember remain that:

  • The law prohibiting the advertising of unapproved medicines in New Zealand has not yet been changed.
  • Advertising unapproved medicines in New Zealand, even to medical professionals at conferences and trade events, remains a criminal offence under section 20 of the Medicines Act 1981 and is subject to a fine of up to NZ$100,000 and, in the case of individuals, imprisonment for up to 6 months.

For further information on medicine regulation in New Zealand, contact our New Zealand experts, Paul Johns, Julie Balance and Sally Paterson.

Zydus Receives Tentative Approval from FDA for Olaparib Tablets

On 7 November 2025, Medical Dialogues reported that Zydus Lifesciences has received tentative approval from the FDA for olaparib tablets, 100 mg and 150 mg, referencing AstraZeneca/MSD’s Lynparza®.

In February 2025, AstraZeneca and MSD’s Lynparza® was accepted in Scotland for reimbursement for the treatment of adults with BRCA1 or 2 mutated HER2-negative advanced breast cancer, who have already received appropriate treatments for their type of breast cancer.

In December 2024, AstraZeneca and MSD announced positive results for Lynparza® in the treatment of breast cancer, demonstrating a reduced risk of death by 28%.

Boan Biotech’s MAAs for Biosimilar Denosumab Accepted in UK

On 7 November 2025, Boan Biologics announced that the UK Medicines and Healthcare products Regulatory Agency (MHRA) has accepted its marketing authorisation applications (MAAs) for two denosumab injections: 60mg (BA6101; biosimilar to Amgen’s Prolia®) and 120mg (BA1102; biosimilar to Amgen’s Xgeva®).

There are five sponsors with denosumab biosimilars approved in the UK, including: Sandoz’s Wyost® and Jubbonti® (November 2024), Samsung Bioepis’ Obodence™ and Xbryk™ (March 2025), Celltrion’s Stoboclo® and Osenvelt® (May 2025), Accord’s Osvyrti® (June 2025) and Biocon’s Evfraxy® and Vevzuo® (July 2025).

Boan Biotech’s denosumab biosimilars have previously been approved in China in 2024 (Boluojia®; BA11021) and 2022 (Boyoubei®; BA6101).

Hikma Launches Biosimilar Ustekinumab in the US

On 6 November 2025, Hikma Pharmaceuticals announced its US launch of Starjemza™, biosimilar to J&J/Janssen’s Stelara® (ustekinumab).  This is the first biosimilar Hikma has launched in the US.

Starjemza™ was approved by the FDA in May 2025.  It is commercialised in the US by Hikma under an exclusive commercialisation and licence agreement with Bio-Thera entered in August 2021.  Bio-Thera remains responsible for the development and manufacture of the product.

Other ustekinumab biosimilars launched in the US to date are: Amgen’s Wezlana® (January 2025), Alvotech/Teva’s Selarsdi® (February 2025), Samsung Bioepis/Sandoz’s Pyzchiva® (February 2025), Biocon’s Yesintek® (February 2025), Formycon/Fresenius Kabi’s Otulfi® (March 2025) and Celltrion’s Steqeyma® (March 2025).

Samsung Bioepis and J&J Settle Dispute Over EU Biosimilar Ustekinumab

On 6 November 2025, Samsung Bioepis announced that it has signed a settlement and licence agreement with Johnson & Johnson (J&J) in relation to the European commercialisation of Pyzchiva® (SB17), biosimilar to Stelara® (ustekinumab).

While the terms of the agreement are confidential, the settlement is expected to resolve a pending Dutch Supreme Court appeal in relation to Janssen’s Supplementary Protection Certificate (SPC) for EP 1 309 692 B1 regarding ustekinumab.  The appeal followed an April 2025 SPC Waiver ruling of the Hague Court of Appeal upholding an earlier decision that Samsung Bioepis did not infringe the SPC by manufacturing and stockpiling Pyzchiva® for export outside the European Union.

The parties have been involved in a number of disputes regarding the validity of Janssen’s European patents for ustekinumab, including EP 3883606, relating to the use of ustekinumab for treating ulcerative colitis.  In September 2025, the District Court of The Hague held that the Dutch equivalent of the patent was valid.  A year earlier, in September 2024, Justice Meade of the High Court of Justice of England and Wales refused Janssen leave to appeal from an earlier decision that the UK counterpart of the patent was invalid.  Samsung Bioepis’ opposition to EP 3883606 in the European Patent Office was discontinued on 3 November 2025, after Samsung Bioepis formally withdrew it.

Pyzchiva® is commercialised by Sandoz in EEA, Switzerland, UK, US and Canada pursuant to a deal entered into in September 2023 between Sandoz and Samsung Bioepis.  Pyzchiva® was approved by the European Commission in April 2024, and was launched by Sandoz in Europe in July 2024.

Samsung Bioepis and J&J settled US litigation regarding ustekinumab in 2023, permitting Samsung Bioepis/Sandoz to commercialise Pyzchiva® in the US in February 2025.

Alvotech/Advanz’s Golimumab UK Approved

On 6 November 2025, Alvotech and Advanz Pharma announced that the UK Medicines and Healthcare products Regulatory Agency (MHRA) has approved Gobivaz® (AVT05), biosimilar to J&J’s Simponi® (golimumab).  The approval covers both pre-filled syringe and autoinjector dosage forms (50 mg/0.5 mL and 100 mg/mL) of Gobivaz®, which is indicated for rheumatoid arthritis, psoriatic arthritis, axial spondylarthritis, ulcerative colitis in adults and juvenile idiopathic arthritis.

Gobivaz® is being commercialised by Advanz in the UK and Europe under a May 2023 licence and supply agreement with Alvotech, which is responsible for development and commercial supply of the product.

AVT05 was the first golimumab biosimilar to be approved worldwide, with its September 2025 approval in Japan, where it is being commercialised by Fuji Pharma.  Also in September 2025, Gobivaz® received a positive opinion from the European Medicine Agency’s CHMP, after Alvotech/Advanz’s European MAA for that product was the first golimumab biosimilar MAA to be accepted anywhere in the world (November 2024).

In the US, Alvotech/Teva’s Biologics Licence Application (BLA) for AVT05 was accepted by the FDA in January 2025.  The FDA issued a Complete Response Letter in relation to the BLA in early November 2025, with Alvotech working to resolve “certain deficiencies” identified following a manufacturing facility inspection.

A golimumab biosimilar, BAT2506, is also being developed by Bio-Thera, with an MAA for the product accepted in Europe in February 2025 (where it is being commercialised by STADA under a May 2024 agreement), and a BLA accepted for FDA review in July 2025 (with Accord responsible for US commercialisation).  Bio-Thera has also entered into commercialisation agreements for BAT2506 with SteinCares for Latin America (March 2024) and Dr Reddy’s for South East Asia (March 2025).

Amgen Commences 2 Further BPCIA Denosumab Litigations – Against Alvotech/Dr Reddy’s & Amneal/mAbxience

On 6 November 2025, Amgen filed two separate BPCIA litigation suits in the US District Court for the District of New Jersey, against each of Dr Reddy’s/Alvotech and Amneal/mAbxience, asserting infringement of 31 US patents covering denosumab, pharmaceutical compositions of denosumab, methods of manufacturing therapeutic proteins like denosumab, and denosumab products.

The litigation follows the FDA’s March 2025 acceptance for review of both Alvotech/Dr Reddy’s Biologics Licence Application (BLA) for AVT03 and Amneal/mAbxience’s BLA for its denosumab biosimilars (MB09).

Under a partnership announced in October 2023, Amneal/mAbxience’s denosumab biosimilars are being developed and manufactured by mAbxience, with Amneal pursuing regulatory approval and having exclusive US commercialisation rights.  In May 2024, Dr Reddy’s and Alvotech entered into a licence and supply agreement for the commercialisation of AVT03, under which Alvotech develops and manufactures the product and Dr Reddy’s will commercialise it exclusively in the US, and semi-exclusively in the EU and UK.

The filing of the two new complaints means Amgen currently has four US proceedings pending regarding denosumab biosimilars, including lawsuits against Hikma/Gedeon Richter and Shanghai Henlius/Organon, commenced on 25 June 2025.  Amgen has settled a further six US proceedings relating to denosumab biosimilars with:

Biocad Commences Ph III Clinical Trial of Biosimilar Ocrelizumab

On 6 November 2025, Biocad announced that it is commencing enrolment for a Phase III clinical trial of BCD-281, biosimilar to Roche’s Ocrevus® (ocrelizumab).  The study, to be conducted in Russia, will aim to evaluate the efficacy and safety of BCD-281 in comparison with Ocrevus®.

According to Biocad, BCD-281 was previously studied in a Ph I clinical trial, which confirmed its biosimilarity with Ocrevus® across all comparable parameters.

There are a number of ocrelizumab biosimilars currently in development.  On 7 August 2025, Sandoz announced that it is streamlining the clinical development programs for its ocrelizumab biosimilar, CYB704, including modifying its Phase 1/3 trial so that it will become a comparative pharmacokinetic trial.  In January 2025, Amgen revealed that it currently has an ocrelizumab biosimilar (ABP 692) undergoing Phase 3 trials.  Celltrion also has an ocrelizumab biosimilar in development, announcing in August 2023 that the European Medicines Agency (EMA) had partially approved its Phase 3 IND for CT-P53 (ocrelizumab).

Sandoz Acquires Continuous Manufacturing Company Just-Evotec for USD 350M

On 4 November 2025, Sandoz and Evotec SE announced they have signed an agreement for Sandoz’s acquisition of 100% of Just-Evotec Biologics EU SAS (including its Toulouse manufacturing site), together with an indefinite technology licence to Evotec’s continuous manufacturing platform technology (J.POD).  The transaction follows a non-binding term sheet signed by the companies in July 2025 relating to the potential acquisition.

Under the agreement, Sandoz will pay an upfront cash consideration of approximately USD 350 million.  Sandoz will also pay additional upfront licence fees for Just Evotec’s continuous manufacturing technology for an indefinite number of molecules, up to 10 of which are royalty bearing.  According to the companies, additional licence fees and development revenues, including success-based milestones, may add up to more than US 300 million over “the coming years”.

The transaction is expected to close in 2025, subject to meeting customary closing conditions, including foreign direct investment clearance by the French authorities.  Upon closing, Just-Evotec Biologics employees will become part of Sandoz.

Sandoz and Just-Evotec have partnered in relation to the development and manufacturing of biosimilars since May 2023.  That partnership was expanded in July 2024, with Sandoz securing long-term commercial supply access to Just-Evotec’s biosimilar manufacturing facility in Toulouse.

First Patient Enrolled in Phase I/III Clinical Trials for Xbrane/Intas’ Nivolumab Biosimilar

On 4 November 2025, Xbrane Biopharma announced that the first patient has been enrolled in the clinical trial of Xdivane™, biosimilar to BMS’ Opdivo® (nivolumab).  The trial is sponsored by Intas, which entered into a global licence agreement with Xbrane for Xdivane™ in November 2024.  Xbrane previously reported that the FDA and EMA had both supported a streamlined combined Phase I and III trial.

Xdivane™ is one of several nivolumab biosimilar candidates lining up to compete with BMS’ Opdivo®.  Others include Amgen’s ABP 206, Reliance Life Science’s RLS-Nivolumab, Enzene’s candidate, Boan Biotech’s BA1104, NeuClone’s candidate and Zydus’ ZRCr-4276.  In August 2025, Sandoz wound down its Phase III trial of JPB898 as a measure to streamline its biosimilar nivolumab development program following feedback from regulatory authorities regarding requirements for biosimilar approvals.

Outlook Therapeutics Resubmits Ophthalmic Bevacizumab BLA to FDA

On 3 November 2025, Outlook Therapeutics announced that it has re-submitted its Biologics Licence Application (BLA) to the US FDA for its ophthalmic formulation of bevacizumab, ONS-5010/Lytenava™, for wet AMD.

The resubmission follows the company’s Type A meeting with the FDA in September 2025 to address the Complete Response Letter (CRL) issued in August 2025.  Outlook Therapeutics “believe[s] this resubmission will resolve the outstanding issue highlighted” in the August 2025 CRL.

Outlook had already resubmitted its BLA to the FDA in February 2025, following receipt of a first CRL from the FDA for ONS-5010 and its submission of a Special Protocol Assessment request in 2023 regarding further clinical trials.  A second CRL (August 2025) recommended Outlook submit additional efficacy data to support its application for ONS-5010.

Lytenava™ received marketing authorisation in the EU in May 2024 and was launched in the UK and Germany for wet AMD in June 2025.  The Scottish Medicines Consortium also accepted Lytenava™ for use within NHS Scotland in June 2025.

Intas Pharmaceuticals reportedly has an ophthalmic bevacizumab biosimilar under development, having received approval from India’s CDSCO in March 2025 to conduct Phase 2/3 trials of bevacizumab (solution for intravitreal injection 25mg/mL) in patients with wet AMD.

FDA Issues CRL for Alvotech’s Biosimilar Golimumab

On 2 November 2025, Alvotech announced that the FDA has issued a complete response letter (CRL) for Alvotech’s Biologics Licence Application (BLA) for AVT05, biosimilar to J&J’s Simponi® (golimumab) in pre-filled syringe and autoinjector presentations.  The CRL follows a pre-licence inspection of Alvotech’s Reykjavik manufacturing facility in July 2025 which identified “certain deficiencies” to be resolved.  The CRL did not identify any other deficiencies with the BLA.

Alvotech’s Chairman and CEO, Robert Wessman, said that Alvotech is “disappointed in receiving the CRL” but expects “to resolve any outstanding issues and will continue to work with the FDA to bring this first to market biosimilar to patients in the US”.

AVT05 is being commercialised in the US by Teva pursuant to a strategic partnership entered into with Alvotech in August 2020.  Alvotech/Teva’s Biologics Licence Application (BLA) for AVT05 was accepted by the FDA in January 2025.

AVT05 was the first golimumab biosimilar to be approved worldwide, with its September 2025 approval in Japan, where it is being commercialised by Fuji Pharma.  It was also the subject of the first golimumab biosimilar MAA to be accepted anywhere in the world, when the European MAA for AVT05/Gobivaz® was accepted in November 2024.  Gobivaz® received a positive CHMP opinion in Europe in September 2025.

Samsung Bioepis Invalidates Regeneron’s Korean Aflibercept Formulation Patent

On 1 November 2025, HITNews reported that Samsung Bioepis has overturned a 2024 decision of the Korean Intellectual Property Trial and Appeal Board (IPTAB) which found that a Regeneron patent for ophthalmic formulations of aflibercept (the Korean equivalent to US Patent No. 11,084,865) was valid.  The Korean patent has now been invalidated by the First Division of the Korean Patent Court.  An injunction granted in May 2025 based on the patent, preventing Korean sales of Samsung Bioepis’ Afilivu® (SB15), biosimilar to Regeneron’s Eylea® (aflibercept), is expected to be lifted.

This latest success for Samsung Bioepis follows a ruling in its favour by the Seoul Central District Court in February 2025, in a proceeding commenced by Regeneron in January 2023 seeking to prevent Samsung Bioepis from producing and selling Afilivu® in Korea.

Afilivu® was the first aflibercept biosimilar approved in Korea in February 2024.  In April 2024, it was reported that Samil Pharmaceutical would launch Samsung Bioepis’ aflibercept biosimilar in the Korean market from 1 May 2024.

On 29 January 2025, the US Court of Appeals for the Federal Circuit refused to overturn a preliminary injunction preventing Samsung Bioepis from launching its aflibercept biosimilar in the US without a licence from Regeneron.  This ruling affirmed an earlier decision of the US District Court for the Northern District of West Virginia in June 2024, finding that Samsung Bioepis infringed, and had failed to raise a substantial question of invalidity of, Regeneron’s US Patent No. 11,084,865 regarding ophthalmic formulations of aflibercept.

Accord’s Denosumab Biosimilars Approved in Australia

On 31 October 2025, Accord’s denosumab biosimilars, referencing Amgen’s Prolia® and Xgeva®, were approved by Australia’s Therapeutic Goods Administration (TGA) as follows:

  • DENOLIA (450306) and DESKELTIA (450307) – denosumab 60mg/1mL solution for injection prefilled syringe with automatic needle guard;
  • DOSTIVA (450305) and DEXEVA (450308) – denosumab 70mg/mL (120mg/1.7mL) solution for injection vial.

Accord is the fourth sponsor to obtain approval of denosumab biosimilars in Australia, following Sandoz’s Jubbonti® and Wyost® (August 2024)Celltrion’s Stoboclo® and Osenvelt® (April 2025), and Samsung Bioepis’ Ospomyv® and Xborso® (July 2025).

On 1 August 2025, Sandoz’s Jubbonti® and Wyost® became the first biosimilars to Amgen’s Prolia® and Xgeva® to be PBS-listed.  At its November 2025 meeting, Australia’s Pharmaceutical Benefits Advisory Committee (PBAC) will consider Celltrion’s denosumab biosimilars, Stoboclo® and Osenvelt®, for PBS-listing for all reference indications.

In April 2025, Amgen commenced Court proceedings in Australia seeking preliminary discovery of documents from Sandoz in relation to its denosumab biosimilars.  That proceeding concluded and Amgen commenced patent infringement litigation against Sandoz in the Federal Court of Australia in June 2025.

ABC Northern Territory Talks to Kim Evans About Bad Faith Trade Marks

When is a trade mark application filed in bad faith?

Pearce IP’s Kimberley Evans discusses the recent trade mark decision of Rallen Australia Pty Limited v Tamboran Resources Limited [2025] ATMO 212 with ABC‘s Sam Parry in NT Country Hour with Matt Brann.

As Kim explains “choosing to trade mark the name of someone else’s property did “seem like a really provocative move”, but proving the application had been filed in bad faith under Australia’s trade mark laws was difficult”.

Boan Biotech Completes Enrolment in Biosimilar Nivolumab Ph III Study

On 30 October 2025, Boan Biotech announced that it has completed enrolment for the clinical phase III study of its self-developed BA1104, biosimilar to BMS’ Opdivo® (nivolumab).  The study is being conducted in China and is aimed at comparing the efficacy, safety, and immunogenicity of BA1104 versus Opdivo® when combined with chemotherapy for treating patients with advanced or metastatic oesophageal squamous cell carcinoma.

While Boan Biotech’s trial is reported to be the first one for a nivolumab biosimilar in China, at least Amgen, Sandoz, Xbrane/Intas, Enzene and Reliance Life Sciences also have nivolumab biosimilars in development.  Zydus received regulatory approval for its nivolumab biosimilar from India’s CDSCO in July 2024 but has since faced injunction proceedings before the Delhi High Court.

Boan Biotech has received marketing approval in China for other biosimilars, including Boyoubei® (November 2022) and Boluojia® (May 2024), referencing Amgen’s Prolia® and Xgeva® (denosumab), respectively.  In July 2024, Boan announced that it had its application for biosimilar aflibercept, BA9101, accepted for evaluation in China.  Boan Biotech has also conducted trials on dulaglutide and bevacizumab biosimilars.

Celltrion’s Denosumab Biosimilars Second Approved in New Zealand

On 30 October 2025, New Zealand’s Medsafe approved Celltrion’s Stoboclo® and Osenvelt®, biosimilars to Amgen’s Prolia® and Xgeva (denosumab), respectively.  This makes Celltrion’s Stoboclo® and Osenvelt® the second pair of denosumab biosimilars approved in New Zealand, following Sandoz’s Jubbonti® and Wyost® in May 2025.

Celltrion’s denosumab biosimilars have been approved in various regions, including Korea (approved November 2024launched March 2025), Europe (approved February 2025, not yet launched), the US (approved March 2025launched July 2025), Australia (approved April 2025, not yet launched) and Canada (approved September 2025, not yet launched).

In May 2024, Celltrion was sued by Amgen in the District Court of New Jersey for alleged infringement of 29 patents regarding denosumab.  That litigation settled in January 2025, permitting the US launch of Celltrion’s denosumab biosimilars in July 2025.

Celltrion Reports Biosimilar Growth in Japan; Bevacizumab Achieves 50% Market Share

On 30 October 2025, Celltrion announced that, according to IQVIA, its Vegzelma®, biosimilar to Roche/Genentech’s Avastin® (bevacizumab), has achieved 50% market share in Japan, surpassing competing innovator and biosimilars to become that top bevacizumab product.  Celltrion states that Vegzelma® has more than tripled its market share, which stood at 15% the same time last year.

Vegzelma®’s success follows that of Celltrion’s other oncology biosimilar, Herzuma®, referencing Roche’s Herceptin® (trastuzumab), which holds a 74% market share in Japan.  Celltrion further reports that its autoimmune disease portfolio has shown strong performance, with Remsima®, referencing Janssen’s Remicade® (infliximab), and Yuflyma®, referencing AbbVie’s Humira® (adalimumab), achieving market shares of 43% and 14%, respectively.

Celltrion attributes this growth to the success of its localised sales and distribution strategy, tailored to Japan’s Diagnosis Procedure Combination (DPC) system, a reimbursement framework that encourages the use of cost-effective medicines such as biosimilars.

In September 2025, Celltrion announced that its Avtozma®/CT-P47, biosimilar to Roche’s Actemra® (tocilizumab), became the first biosimilar tocilizumab approved in Japan.  This followed the Japanese launch of Celltrion’s biosimilar ustekinumab, Steqeyma®, referencing J&J/Janssen’s Stelara®, in July 2025.

Glyconex Completes Ph 3 Biosimilar Denosumab Trial

On 29 October 2025, GlycoNex announced that the last patient has received the final dose in its phase 3 clinical study of SPD8, biosimilar to Amgen’s Prolia®/Xgeva® (denosumab).  The trial, which was commenced in late 2024, is assessing the efficacy, safety and immunogenicity of SPD8 in patients with osteoporosis.  GlycoNex plans to report top-line results from the study in the second quarter of 2026.

SPD8 was developed by GlycoNex in collaboration with Mitsubishi Gas Chemical.  In December 2024, GlycoNex entered into a licensing agreement with an undisclosed partner for SPD8, under which the licensee will be responsible for developing SPD8, securing regulatory approval, and commercialising the biosimilar in an undisclosed market.

Denosumab biosimilars have been approved around the world, including seven pairs of denosumab biosimilars approved in the US: Sandoz’s Jubbonti® and Wyost® (approved March 2024launched June 2025), Samsung Bioepis’ Obodence™ and Xbryk™ (approved February 2025, not yet launched), Celltrion’s Stoboclo® and Osenvelt® (approved March 2025launched July 2025), Fresenius Kabi’s Conexxence® and Bomyntra® (approved March 2025launched July 2025), Shanghai Henlius/Organon’s Bildyos® and Bilprevda® (approved September 2025, not yet launched), Biocon’s Bosaya™ and Aukelso™ (approved September 2025, launched October 2025) and Richter/Hikma’s Enoby™ and Xtrenbo™ (approved September 2025, not yet launched).

Fresenius & Celltrion Secure US Interchangeability for Denosumab Biosimilars

The FDA has approved denosumab biosimilars Conexxence® and Bomyntra® (Fresenius Kabi) and Stoboclo® and Osenvelt® (Celltrion) as interchangeable with Amgen’s Prolia® and Xgeva®, respectively, for all approved indications, effective as of 29 October 2025.

Fresenius Kabi launched Conexxence® and Bomyntra® in early July 2025, following a global settlement agreement with Amgen, resulting in the dismissal of US BPCIA litigation commenced by Amgen in October 2024.  Amgen and Celltrion also settled their BPCIA litigation in January 2025, with Celltrion launching Stoboclo® and Osenvelt® in July 2025.

There are seven pairs of denosumab biosimilars approved in the US: Sandoz’s Jubbonti® and Wyost® (approved March 2024, launched June 2025), Samsung Bioepis’ Obodence™ and Xbryk™ (approved February 2025, not yet launched), Celltrion’s Stoboclo® and Osenvelt® (approved March 2025, launched July 2025), Fresenius Kabi’s Conexxence® and Bomyntra® (approved March 2025, launched July 2025), Shanghai Henlius/Organon’s Bildyos® and Bilprevda® (approved September 2025, not yet launched), Biocon’s Bosaya™ and Aukelso™ (approved September 2025, launched October 2025), and Richter/Hikma’s Enoby™and Xtrenbo™ (approved September 2025, not yet launched).

Samsung Bioepis Obtains Full European Commercialisation Rights for Ranibizumab and Aflibercept Biosimilars

On 29 October 2025, Samsung Bioepis announced that it has entered into an Asset Purchase Agreement with Biogen in Europe for Samsung Bioepis’ two ophthalmology biosimilars: Byooviz® (biosimilar to Genentech’s Lucentis® (ranibizumab)) and Opuviz™ (biosimilar to Regeneron/Bayer’s Eylea® (aflibercept)).

Samsung Bioepis and Biogen had partnered in November 2019 in relation to commercialisation of the two ophthalmology biosimilars in the US, Canada, Europe, Japan and Australia.  In October 2024, Biogen decided to terminate the November 2019 agreement with Samsung Bioepis within the US and Canada.  In July 2025, Samsung Bioepis entered into an agreement with Harrow, under which Harrow will assume full commercial responsibility for Byooviz® and Opuviz™ in the US upon full transition of Biogen’s commercialisation rights back to Samsung Bioepis by the end of 2025.

Under the Asset Purchase Agreement announced this week, Samsung Bioepis will be responsible for commercialising Byooviz® in Europe from January 2026 once the transfer of commercial rights from Biogen back to Samsung Bioepis takes effect.  Samsung Bioepis will launch Opuviz™ in Europe following the lapse or revocation of relevant patent(s) for Eylea®.

Byooviz® has been commercially available in several European countries since March 2023, following its approval in August 2021 as the first ophthalmology biosimilar in the region for the treatment of patients with nAMD, macular oedema following retinal vein occlusion (RVO), and myopic choroidal neovascularisation (mCNV).  Other EU approved ranibizumab biosimilars include Formycon’s Ranivisio® (approved August 2022, being commercialised in the EU by Teva), Lupin’s biosimilar (being marketed in the EU by Sandoz); and STADA/Xbrane’s Ximluci® (approved November 2022).

There are currently 10 aflibercept biosimilars approved in Europe:  Biocon’s Yesafili® (September 2023)Sandoz’s Afqlir® (November 2024)Samsung Bioepis/Biogen’s Opuviz™ (SB15) (November 2024)Formycon/Klinge’s Baiama® and Ahzantive® (January 2025)Celltrion’s Eydenzelt® (February 2025)Amgen’s Pavblu® (April 2025)Alvotech/Advanz’s Mynzepli® (August 2025) and Alteogen’s Eyluxvi® (September 2025).  Sam Chun Dang announced on 20 August 2025 that its aflibercept biosimilar received EU marketing authorisation, although the name of the product is not yet known.

FDA to Streamline Biosimilar Approvals and Interchangeability

On 29 October 2025, the FDA announced proposed measures to make it faster and less costly to develop biosimilars, by simplifying biosimilarity studies, reducing unnecessary clinical trials and facilitating pharmacy level substitution.

In a new draft guidance, entitled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product: Updated Recommendations for Assessing the Need for Comparative Efficacy Studies”, the FDA recommends that biosimilar sponsors consider a streamlined approach in which a clinical efficacy study (CES) may not be necessary to support a demonstration of biosimilarity.  The FDA suggests that this approach should be considered when:

  • the reference product and biosimilar are manufactured from clonal cell lines, are highly purified and can be well characterised analytically;
  • the relationship between quality attributes and clinical efficacy is generally understood for the reference product and can be evaluated by assays included in the comparative analytical assessment; and
  • a human pharmacokinetic similarity study is feasible and clinically relevant.

In these circumstances, the adequacy of data from a comparative analytical assessment, pharmacokinetic similarity data, and immunogenicity assessment to support a demonstration of biosimilarity would be evaluated based on the totality of the evidence submitted in the biologics licence application (BLA).

The draft guidance is open for comment for 60 days and is expected to be published in its final form in 3 to 6 months.

In a separate initiative announced at the same time, the FDA also intends to make it easier for biosimilars to be developed as interchangeable with reference products by not requiring switching studies.

The FDA’s announcements follow similar initiatives in other regions, including the European Medicines Agency’s April 2025 reflection paper considering the possible waiver of comparative efficacy study requirements for biosimilars and India’s revised draft biosimilar guidelines in May 2025.
