On 28 August 2025, Celltrion announced that it has launched two biosimilars in Vietnam:

• Remsima® SC, biosimilar to Janssen’s Remicade® (infliximab); and
• Herzuma®, biosimilar to Roche/Genentech’s Herceptin® (trastuzumab).

Alongside this launch, Celltrion states that it has secured a one-year supply agreement for Remsima® SC with the largest military hospital in Vietnam and a two-year tender to supply Herzuma® to medical institutions in the central and southern regions of the country.

Celltrion has successfully tendered for the supply of Remsima® and Herzuma® in a number of key regions over the past two years, including Brazil (September 2024), and of Remsima SC® in Denmark (April 2024), Norway (February 2024) and Sicily (January 2024).

In February 2024, Celltrion secured a series of tenders in Peru to supply Herzuma® (trastuzumab biosimilar), Truxima® (rituximab biosimilar) and Yuflyma® (adalimumab biosimilar).  In June 2024, Celltrion successfully applied to be the exclusive supplier of Remsima®, Herzuma® and Vegzelma® (bevacizumab biosimilar) to France’s largest pharmaceutical procurement group (Union des Hopitaux pour les Achats (UniHA)), until 2027.

Earlier this month, Celltrion’s Remsima® IV formulation was recommended for listing on Australia’s Pharmaceutical Benefits Scheme for reimbursement.  Remsima® IV was approved by Australia’s TGA in November 2015, while Remsima® SC received approval in November 2020 (PBS-listed July 2021).

On 22 August2025, the outcomes of Australia’s Pharmaceutical Benefits Advisory Committee (PBAC) July 2025 meeting were published, including recommendations for the listing of three biosimilars on the Pharmaceutical Benefits Scheme (PBS).

Sandoz’s aflibercept biosimilars, Afqlir® and Enzeevu™, have been recommended for PBS-listing under the same circumstances as reference biologic, Regeneron/Bayer’s Eylea®.  Sandoz’s Afqlir® and Enzeevu® were approved by the TGA on 27 May 2025 and were the first aflibercept biosimilars to be considered (and now recommended) for reimbursement.  Celltrion’s Eydenzelt® was the first aflibercept biosimilar TGA-approved on 31 March 2025 (solely for myopic CNV).

Biocon Biologic’s Nepexto® (pre-filled syringe), biosimilar to Amgen/Pfizer’s Enbrel® (etanercept), was also recommended for PBS-listing (sponsor: Maxx Pharma).  Nepexto® (50mg/1ml auto-injector) became the second etanercept biosimilar to be PBS-listed as of 1 July 2025, following Samsung Bioepis/Arrow Pharma’s Brenzys® in April 2017.  In July 2025, Biocon Biologics announced that it launched Nepexto® in Australia.

Celltrion’s Remsima® (IV formulation), biosimilar to Janssen’s Remicade® (infliximab), has also been recommended by PBAC.  Remsima® IV was approved by the TGA in November 2015, while Remsima® SC received approval in November 2020 (PBS-listed July 2021).

Among the originator biopharmaceuticals, Roche/Genentech’s Ocrevus® (ocrelizumab) SC formulation was recommended for PBS listing under the same circumstances as the IV formulation, following its approval in Australia in March 2025.

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 nivolumab and ocrelizumab biosimilars, which includes modifying its Phase 1/3 trial for biosimilar ocrelizumab, CYB704, 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).

On 21 August 2025, New Zealand’s Medsafe approved Pfizer’s Ixifi®, biosimilar to Janssen’s Remicade® (infliximab), in 100mg IV formulation for all reference indications.

Ixifi® will be the second infliximab biosimilar available in New Zealand, following Celltrion’s Remsima® (SC formulation, 120mg/ml pre-filled pen and pre-filled syringe), approved in June 2023.

Pfizer’s Inflectra® branded infliximab biosimilar (100mg IV formulation) was initially approved by Medsafe in September 2015, but the company no longer supplies or markets the product.  Similarly, Samsung Bioepis’ infliximab biosimilar, Renflexis® (100mg IV formulation), was approved by Medsafe in March 2023, but is also no longer supplied or marketed in New Zealand.

Pfizer and Celltrion entered into a 2009 agreement for biosimilar infliximab, with Pfizer holding exclusive commercialisation rights in the US and certain other jurisdictions.  In March 2025, Celltrion announced the rebrand of Inflectra® (IV formulation) to Remdantry™ in Canada.  According to Celltrion, the rebrand reflected its “consolidation of both the intravenous (IV) and subcutaneous (SC) formulations” being directly commercialised by Celltrion in Canada in order to “provide healthcare professionals with a more streamlined prescribing experience”.

On 2 July 2025, Navlin Daily reported that the Spanish Ministry of Health issued a tender for the sustainable supply of biologics and biosimilars under a two-year Framework Agreement worth €411 million coordinated by the Instituto Nacional de Gestión Sanitaria (INGESA).

According to the report, this second-phase agreement builds upon the initial framework launched in late 2022, which generated over €120 million in cost savings to date.  The new agreement is expected to deliver an additional €178 million in savings and will comprise 17 therapeutic categories covering biologics that have approved biosimilars.  The Framework Agreement includes the following biologics, among others: adalimumab, etanercept, infliximab, rituximab, trastuzumab, pegfilgrastim, bevacizumab, tocilizumab, natalizumab, eculizumab, ranibizumab and ustekinumab.

INGESA will select between 25 and 50 suppliers using an open procedure, with contracts awarded based on 70% price and 30% quality weighting.

On 11 March 2025, Celltrion announced that its biosimilar infliximab for injection, currently known as Inflectra®, will be rebranded to Remdantry™ in Canada commencing on 1 April 2025.  The formulation, indications and dosages of Remdantry™ will remain the same as those for Inflectra®.

According to Celltrion, the rebrand reflects its “consolidation of both the intravenous (IV) and subcutaneous (SC) formulations” being directly commercialised by Celltrion in Canada in order to “provide healthcare professionals with a more streamlined prescribing experience”.

Inflectra®, biosimilar to Janssen’s Remicade®, was approved by Health Canada for the treatment of rheumatoid arthritis (RA), plaque psoriasis (PsO), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) in January 2014 and for Crohn’s disease (CD), fistulising Crohn’s disease and ulcerative colitis (UC) in June 2016.

Celltrion’s SC infliximab, Remsima™ SC, was approved by Health Canada for RA in January 2021 and for UC and Crohn’s disease in February 2024.

On 20 December 2024, Australia’s Pharmaceutical Benefits Assessment Committee (PBAC) published the outcomes considered at its November 2024 meeting.

The following biosimilars were recommended for listing on the Pharmaceutical Benefits Scheme (PBS):

• Sandoz’s Wyost®, biosimilar to Amgen’s Prolia® and Xgeva® (denosumab), for osteoporosis, giant cell tumour of bone, and bone metastases
• Celltrion’s Steqeyma®, biosimilar to Janssen’s Stelara® (ustekinumab), for severe chronic plaque psoriasis, severe psoriatic arthritis, Crohn’s disease, complex refractory fistulising Crohn’s disease, and moderate to severe ulcerative colitis.

Among the originator biopharmaceuticals, Bayer secured a recommendation for its Eylea® (aflibercept) indication expansion for diabetic macular oedema and subfoveal choroidal neovascularisation secondary to age-related macular degeneration.  Novo Nordisk’s Ozempic® (semaglutide) also received a positive recommendation for type 2 diabetes mellitus, following its application for a new strength formulation.

Several oncology treatments received positive recommendations, including Janssen’s Rybrevant® (amivantamab) for non-small cell lung cancer.  Other cancer treatments recommended include Amgen’s Blincyto® (blinatumomab) for MRD-negative B-cell precursor acute lymphoblastic leukaemia, AstraZeneca’s Imfinzi® for use in combination with platinum-based chemotherapy for the treatment of deficient mismatch repair (dMMR) endometrial cancer, and Astellas Pharma’s Padcev® (enfortumab vedotin) for locally advanced or metastatic urothelial cancer.

AbbVie’s Epkinly® (epcoritamab) received a recommendation for relapsed or refractory diffuse large B-cell lymphoma, while Novartis’ Aimovig® (erenumab) was recommended for chronic migraine.

For hereditary angioedema, both CSL’s garadacimab and Takeda’s Takhzyro® (lanadelumab) secured positive recommendations.

Additional recommendations were granted to BMS’s Opdivo® (nivolumab) for urothelial carcinoma, MSD’s Keytruda® (pembrolizumab) for renal cell carcinoma, and Alexion Pharmaceuticals’ Ultomiris® (ravulizumab) for Neuromyelitis Optica Spectrum Disorder.

BeiGene’s Tevimbra® (tislelizumab) also received a positive recommendation for oesophageal squamous cell carcinoma.

The PBAC reports that some earlier recommendations have been extended:

• Sanofi’s Dupixent® (dupilumab) for chronic severe atopic dermatitis and uncontrolled severe asthma

Additionally, two recommendations have been rescinded:

• Celltrion Remsima SC® (infliximab) for rheumatoid arthritis
• AbbVie’s Skyrizi® (risankizumab) for Crohn’s disease

On 28 November 2024, Australia’s Pharmaceutical Benefits Scheme (PBS) published its agenda for the March 2025 Pharmaceutical Benefits Advisory Committee (PBAC) meeting.  This follows the PBAC’s publication of its September 2024 intracycle meeting outcomes, which noted that, to date, it had not received an acceptable proposal for an expanded listing to facilitate broad access to PD-(L)1 inhibitors which includes MSD’s pembrolizumab and BMS’ nivolumab.   

For the March 2025 agenda, half of the submissions selected for consideration are for monoclonal antibodies, 17 of which are list for new PBS additions and 6 for amendments. 

Four biosimilars will be considered for new listings: 

• Pfizer’s Ixifi®, biosimilar to Janssen’s Remicade® (infliximab), for severe active rheumatoid arthritis, ankylosing spondylitis, severe psoriatic arthritis, severe chronic plaque psoriasis, severe Crohn disease, complex refractory fistulising Crohn Disease, and moderate to severe ulcerative colitis 

• Sandoz’s Tyruko®, biosimilar to Biogen’s Tysabri® (natalizumab), for relapsing-remitting multiple sclerosis 

• Celltrion’s Omlyclo®, biosimilar to Novartis’ Xolair® (omalizumab), for uncontrolled severe asthma, uncontrolled severe allergic asthma, and severe chronic spontaneous urticaria 

• Samsung Bioepis’ Epyztek®, biosimilar to Janssen’s Stelara® (ustekinumab), for severe chronic plaque psoriasis, severe psoriatic arthritis, severe Crohn disease, and complex refractory fistulising Crohn Disease 

One biosimilar is being considered for changes to an existing listing: Celltrion’s Remsima® SC, biosimilar to Janssen’s Remicade® (infliximab). 

Other applications for PBS listing additions or amendments that the PBAC will consider at its March 2025 meeting include the following: 

On 8 November 2024, Celltrion announced that it has achieved accumulated sales for Q3 2024 of KRW 2.4 trillion, surpassing its 2023 annual sales.  Its quarterly sales are the highest it has ever reported, up 31.2% year on year.

Celltrion attributes its sales growth to the expansion of global prescriptions for its subcutaneous infliximab, Remsima SC® (EU, launched in 2020)/Zymfentra™ (US, launched in March 2024), biosimilar adalimumab.  Yuflyma® (80mg dose US launch January 2024, 40mg dose first approved by the FDA in May 2023, launched 2023, paediatric form US launch March 2024), and biosimilar bevacizumab, Vegzelma® (US launch April 2023).  It has also experienced steady growth in its anticancer products, Truxima® (rituximab, US launch May 2020) and  Herzuma® (trastuzumab, US launch March 2020).

During 2024, Zymfentra™ secured all six public and private insurance contracts operated by the three major prescription drug managers (PBMs) in the US.  Celltrion estimates that it has now secured more than 90% coverage in the US insurance market by completing contracts with 30 mid- to large-sized and regional PBMs and insurance companies.

Celltrion also notes the expansion of its biosimilar portfolio during 2024 with the launch of SteQeyma® (ustekinumab) in major European countries on 1 November.  Celltrion is planning for the 2025 launch of Eydenzelt® (CT-P42, aflibercept).

Celltrion has a number of biosimilars under development, including CT-P41 (denosumab, US aBLA filed December 2023),  CT-P47 (tocilizumab), CT-P55 (secukinumab), CT-P53 (ocrelizumab) and CT-P51 (pembrolizumab).

On 30 October 2024, Celltrion announced results of a global phase 3, 2-year follow-up study comparing infliximab SC (CT-P13, Zymfentra™) as monotherapy and in combination with immunosuppressants.  Celltrion reports that the study found Zymfentra™ as monotherapy was just as effective and safe as when combined with immunosuppressants for patients with Crohn’s disease or ulcerative colitis, suggesting “monotherapy can be a sufficiently safe and effective treatment option”.  The results were presented at the 2024 American College of Gastroenterology conference (25-30 October 2024).

This news follows Celltrion’s 19 August 2024 announcement that the FDA has approved a phase 3 clinical trial of Zymfentra™ for rheumatoid arthritis.

Zymfentra™ was the first subcutaneous formulation of infliximab approved by the FDA for ulcerative colitis and Crohn’s disease in October 2023.  It was launched in the US in March 2024.

In Europe, Zymfentra™ is known as Remsima SC® and has been approved since 2013.

On 27 September 2024, the Australian Therapeutic Goods Administration (TGA) approved Pfizer’s Ixifi™, biosimilar to Janssen’s Remicade® (infliximab), in 100mg powder for injection vial for the treatment of rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, psoriasis, Crohn’s disease, refractory fistulising Crohn’s disease and ulcerative colitis.

This is the second approval for a Pfizer-sponsored infliximab biosimilar, with Inflectra® having been the first infliximab biosimilar approved in Australia in November 2015.

On 26 September 2024, the TGA provisionally approved Janssen’s Talvey® (talquetamab) in 2mg/ml and 40mg/ml solutions for injection vial for the treatment of adult patients with relapsed or refractory multiple myeloma, who have previously received at least four prior therapies, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody.  Talvey® was granted accelerated approval in the US by the FDA in August 2023.

Also on 26 September 2024, Celltrion’s Yuflyma®, biosimilar to AbbVie’s Humira® (adalimumab), received Australian approval for a lower dose of 20mg/0.2ml solution for injection pre-filled syringe.  Yuflyma® has previously been approved in Australia in 40mg/0.4ml (March 2022) and 80mg/0.8ml (30 June 2023) forms and was PBS listed in March 2023 (40mg/0.4ml).
