On 29 January 2026, Celltrion announced the Canadian approval of its high-dose Omlyclo® (omalizumab), biosimilar to Genentech/Novartis’ Xolair®, in 300mg pre-filled syringe (PFS) and autoinjector (AI) formulations.  Celltrion now has Canadian approved PFS and AI formulations of Omlyclo® in all strengths of Canadian approved Xolair® (75mg, 150mg and 300mg).

Omlyclo® was the first omalizumab biosimilar approved in Canada in December 2024 and remains the only Canadian approved biosimilar omalizumab to date.

The approval of the high dose formulations of Omlyclo® in Canada follows approvals of a PFS presentation of the 300mg dosage form in the US, in December 2025, and in the EU, in November 2025.

Aurobindo, Teva, Glenmark and Kashiv  also have omalizumab biosimilars under development.   On 11 August 2025, Kashiv BioSciences announced that it entered into a licence and supply agreement with Brazilian pharmaceutical company, CRISTÁLIA, for Kashiv’s biosimilar omalizumab, ADL-018, for the Latin American Market.  Kashiv has previously entered into agreements for commercialisation of ADL-018 in other regions, including with MS Pharma for MENA markets (August 2025) and Alvotech for the EU, UK, Australia, Canada and New Zealand (AVT23, October 2023).  A marketing application for AVT23 was accepted by the UK’s MHRA in March 2025 and by the European Medicines Agency in October 2025.

On 24 December 2025, Celltrion announced that it has secured approval in Korea for an autoinjector presentation (75mg and 150 mg) of Omlyclo®, biosimilar to Novartis’ Xolair® (omalizumab).

Omlyclo® (CT-P39) was the first omalizumab biosimilar approved in Korea in June 2024 (as a pre-filled syringe).  With the autoinjector approval in Korea, alongside the recently cleared 300 mg pre-filled syringe in the US, Celltrion reports that it now has a full lineup of pre-filled syringes (75 mg, 150 mg, 300 mg), together with the two autoinjector formulations of Omlyclo®.

Omlyclo® was first approved in the US in March 2025, in 75 mg/0.5ml and 150mg/ml PFS forms, with full interchangeable status.  It has also been approved in the EU (May 2024), Australia (November 2024), Canada (December 2024), and New Zealand (April 2025).

Celltrion commenced its European rollout of Omlyclo® with the launch of the product in Norway in September 2025, and completed its launch in major European countries including Germany, Spain, the UK and France in November 2025.  In late November 2025, Celltrion announced that it launched Omlyclo® in Brazil, Latin America’s largest pharmaceutical market.

Aurobindo, Teva, Glenmark and Kashiv reportedly also have omalizumab biosimilars under development.  On 11 August 2025, Kashiv BioSciences announced that it entered into a licence and supply agreement with Brazilian pharmaceutical company, CRISTÁLIA, for Kashiv’s biosimilar omalizumab, ADL-018, for the Latin American Market.  Kashiv has previously entered into agreements for commercialisation of ADL-018 in other regions, including with MS Pharma for MENA markets (August 2025) and Alvotech for the EU, UK, Australia, Canada and New Zealand (AVT23, October 2023).  A marketing application for AVT23 was accepted by the UK’s MHRA in March 2025.

On 19 November 2025, Australia’s Pharmaceutical Benefits Advisory Committee (PBAC) published its March 2026 agenda, at which the following biosimilars will be considered for reimbursement:

• Amgen’s Amgevita® (adalimumab) in 20mg/0.2ml and 40mg/0.4ml pre-filled syringe (PFS), and 40mg/0.4ml and 80mg/0.8ml pre-filled pen (PFP);
• Celltrion’s Yuflyma® (adalimumab) in 20mg/0.2ml PFS;
• Celltrion’s Omlyclo® (omalizumab) in 75mg/0.5ml and 150mg/1ml PFP; and
• Sandoz’s Ardelya® (ustekinumab) in 45mg/0.5ml and 90mg/1ml PFS.

Amgen received TGA approval for its high-concentration Amgevita® formulations (referencing AbbVie’s Humira® (adalimumab)) in September 2025.  In September 2024, Celltrion’s Yuflyma® was TGA approved in 20mg/0.2ml PFS.  Yuflyma® has previously been approved in Australia in 40mg/0.4ml (March 2022) and 80mg/0.8ml (June 2023) forms and was PBS-listed in March 2023 (40mg/0.4ml).

In addition to Celltrion’s Yuflyma® and Amgen’s Amgevita®, there are a number of other high-concentration adalimumab biosimilars approved in Australia, including Alvotech/Cipla’s Ciptunex®/Adalicip® (September 2022), Samsung Bioepis’ Hadlima® (February 2023) and Sandoz’s Hyrimoz® (May 2024).

In September 2025, Celltrion announced the Australian launch of Omlyclo®, biosimilar to Novartis’ Xolair® (omalizumab).  Omlyclo® is currently the only omalizumab biosimilar approved in Australia, having first been approved in PFS presentations in November 2024 and PBS-listed on 1 August 2025.  The PFP formulations which will be considered by PBAC in March 2026 were approved in August 2025.

Sandoz’s Ardelya®, biosimilar to J&J/Janssen’s Stelara® (ustekinumab), will be considered by PBAC at its March 2026 meeting, although it has not yet received marketing approval in Australia.  While Amgen’s Wezlana® was the first ustekinumab biosimilar recommended for PBS-listing in March 2024, Amgen is no longer proceeding with that listing.  As a result, Celltrion’s Steqeyma® was the first ustekinumab biosimilar to be PBS-listed on 1 August 2025.  Samsung Bioepis’ Epyztek® (ustekinumab) was recommended for PBS-listing at PBAC’s March 2025 meeting, but the current status of the application is recorded as “inactive”.

On 18 November 2025, Celltrion announced that it has received European Commission approval for a new 300 mg (2 mL) prefilled syringe form of Omlyclo®, biosimilar to Novartis’ Xolair® (omalizumab).  According to Celltrion, the additional strength of Omlyclo® “can significantly decrease the frequency of injections and reduce injection burden and discomfort without compromising efficacy and safety”.

Omlyclo® is the first and only omalizumab biosimilar to be approved in the EU, with Celltrion’s 75 mg/0.5 mL and 150 mg/1 mL PFS formulations receiving EU market authorisation in May 2024.
