July 1, 2026, Shanghai, China - Fosun Wanbang (Jiangsu) Pharmaceutical Group Co., Ltd. ("Fosun Wanbang"), a wholly-owned subsidiary of Fosun Pharma (Stock Code: 600196.SH, 02196.HK) recently has entered into a licensing agreement with Shanghai Junshi Biosciences Co., Ltd. ("Junshi Biosciences"; Stock Code: 688180.SH, 01877.HK). Under the agreement, the two parties will cooperate on the development, registration, manufacturing and commercialization of roconkibart (JS005, anti-IL-17A monoclonal antibody) in the Greater China region, which includes the Chinese mainland, Hong Kong SAR, Macau SAR, and Taiwan region.

Roconkibart is a specific anti-IL-17A monoclonal antibody independently developed by Junshi Biosciences. IL (interleukin)-17A is a pleiotropic cytokine, and its disordered secretion is closely related to the occurrence and progression of autoimmune diseases such as psoriasis, rheumatoid arthritis and ankylosing spondylitis. By binding to IL-17A homodimer and IL-17A/IL-17F heterodimer with high affinity and selectively blocking the binding of IL-17A with its receptor IL-17RA/IL-17RC, roconkibart blocks the activation of downstream signaling pathways and the release of inflammatory factors, thereby effectively alleviating the symptoms of autoimmune diseases.

The Phase 3 clinical study of roconkibart for the treatment of patients with moderate to severe plaque psoriasis (PsO) in China has been completed, showing excellent efficacy and safety levels. In the 150 mg dosing group, the Psoriasis Area and Severity Index 90 (PASI 90) response rate at week 16 reached 91%; the PASI 100 response rate at week 52 reached 65%. In December 2025, the new drug application (NDA) for roconkibart in adult patients with moderate to severe PsO who are candidates for systemic therapy or phototherapy was accepted by the National Medical Products Administration (NMPA). Now, the study follow-up for all subjects under the phase 2 clinical study of roconkibart for the treatment of ankylosing spondylitis (AS) has completed.

Li Jing, Co-President of Fosun Pharma and Chairman of Fosun Wanbang, said:"Autoimmune diseases present massive unmet clinical needs and represent a core therapeutic focus for Fosun Pharma. This strategic partnership with Junshi Biosciences is a vital step in continuously enriching our portfolio of high-value pipelines in the immunology and inflammation fields. Roconkibart has delivered outstanding efficacy data in its Phase III clinical trials, demonstrating rapid and durable disease control in the treatment of psoriasis and other indications. Fosun Pharma has established a mature clinical development and commercialization framework in this therapeutic area. Moving forward, we will leverage our respective strengths to accelerate the development and commercialization of Roconkibart in Greater China region, ensuring this breakthrough innovative therapy benefits patients as early as possible."

Dr. Jianjun ZOU, General Manager and CEO of Junshi Biosciences,said, “This strategic collaboration with Fosun Pharma signals a critical expansion of our autoimmune disease treatments. With years of extensive expertise in this domain, Fosun Pharma has established a professional commercialization team and a mature, efficient marketing system, which will inject momentum into roconkibart’s rapid advancement. This not only validates our company's innovative capabilities in the autoimmune sector, but also marks a milestone leap for both parties in meeting patient expectations through robust innovation. We anticipate that this in-depth synergy will accelerate the clinical development and commercialization of roconkibart in the Greater China region, bringing new hope to more patients in urgent need of effective treatments sooner and better.”
