On 18 June 2026, CSPC Pharmaceutical Group announced that China’s National Medical Products Administration (NMPA) has accepted its marketing authorisation application (MAA) for Secukinumab Injection, biosimilar to Novartis’ Cosentyx®.
Cosentyx® is approved in China for the treatment of plaque psoriasis in patients aged 6 years and older; and for psoriatic arthritis, ankylosing spondylitis, hidradenitis suppurativa and non-radiographic axial spondyloarthritis in adults. According to the announcement, In phase 1 and 3 studies, CSPC’s biosimilar demonstrated high similarity to Cosentyx® in terms of efficacy, safety, pharmacokinetics, and immunogenicity.
This news follows Celltrion’s announcement earlier in June 2026 that it has filed an application for its secukinumab biosimilar (CT-P55) in Canada, seeking all approved reference indications. Celltrion is planning additional regulatory filings for CT-P55 in the US, Europe and Korea.
Other secukinumab biosimilars are under development, including Bio-Thera’s BAT2306 (phase 1 trial completed in 2023, phase 3 clinical trial in plaque psoriasis completed in 2024, commercialisation agreement with Dr Reddy’s in November 2025), Taizhou Mabtech Pharmaceutical’s CMAB015 (phase 1 trial completed in 2023) and Livzon Pharmaceutical Group’s LZM012 (phase 3 clinical trial in plaque psoriasis commenced).
