SAN DIEGO, July 09, 2025 (GLOBE NEWSWIRE) — Connect Biopharma Holdings Limited (Nasdaq: CNTB) (“Connect Biopharma”, “Connect”, or the “Company”), a clinical-stage biopharmaceutical company focused on transforming care for the treatment of inflammatory diseases, today announced that the Company’s collaborator and exclusive licensee in China, Simcere Pharmaceutical Co., Ltd. (“Simcere”), has submitted its New Drug Application for rademikibart to the National Medical Products Administration of China (“NMPA”) for the treatment of atopic dermatitis (“AD”) in adults and adolescents.
“Simcere continues to make strong progress in advancing rademikibart in China, our potentially best in class next generation IL-4Rα antibody,” said Barry Quart, Pharm.D., CEO and Director of Connect Biopharma. “Atopic dermatitis remains a large and growing market in China, and rademikibart has the potential to significantly improve the condition for millions of patients.

Connect is also eligible to receive royalties at tiered percentage rates up to low double-digit percentages on net sales in Greater China. The AD market in China represents considerable opportunity, with an estimated 70 million patients with AD.
About
Rademikibart
Rademikibart is a fully human monoclonal antibody targeting interleukin-4 receptor alpha (IL-4Rα), a common subunit of interleukin-4 receptor (IL-4) and interleukin-13 receptor (IL-13). By binding with IL-4Rα, rademikibart can block the functions of IL-4 and IL-13 effectively, thereby blocking the T helper 2 (Th2) inflammatory pathway, thus achieving the goal of treating Th2 related inflammatory diseases such as atopic dermatitis and asthma.
