Accro Bioscience and Fosun Pharma sign licence deal for autoimmune therapy in Greater China
Ella Day | September 4, 2025 | News story | |
Accro Bioscience has granted Shanghai-based Fosun Pharma exclusive rights to develop, manufacture and commercialise its experimental therapy AC-201 in Greater China, accounting for mainland China, Hong Kong and Macau. Accro will retain global rights outside the region.
The deal includes an upfront and near-term milestone payment with a total worth over £8.3m, with additional development and commercial milestone payments. Accro will also receive tiered royalties based on product sales.
AC-201 is an oral therapeutic designed to block TYK2 and JAK1 proteins, which play a role in immune system signalling linked to inflammatory and autoimmune diseases. Unlike some other drugs that target JAK proteins, it has limited effect on JAK2, which may reduce side effects. In a phase 2 trial in patients with moderate-to-severe plaque psoriasis, the drug met all primary and secondary endpoints after 12 weeks. It was generally safe and well-tolerated.
Xiaohu Zhang, co-founder and chief executive of Accro, said: “Partnering with Fosun will accelerate the development of AC-201 and enhance drug accessibility, bringing new treatment options to patients with autoimmune diseases in the region as soon as possible.”
Fosun Pharma intends for the partnership to strengthen its pipeline in immunology and inflammation, an area where it is seeking to expand its research and development.
