Sinopharm Biotech Secures $1.53 Billion Global Licensing Deal for First-in-Class JAK/ROCK Inhibitor Rovadicitinib with Sanofi On March 4, 2026, China Biopharmaceutical Limited (HKEX: 1177) announced a global exclusive licensing agreement between its subsidiary, Chia Tai Tianqing Pharmaceutical Group, and a wholly owned affiliate of Sanofi S.A. for rovadicitinib, a first-in-class oral JAK/ROCK dual inhibitor. Under the deal, China Biopharmaceutical will receive an upfront payment of $135 million and is eligible for up to $1.395 billion in development, regulatory, and sales milestone payments, plus double-digit tiered royalties on net sales. Rovadicitinib was approved by China’s NMPA in February 2026 for first-line treatment of adult patients with intermediate-2 or high-risk primary myelofibrosis, post-polycythemia vera myelofibrosis, or post-essential thrombocythemia myelofibrosis. It also shows breakthrough potential in chronic graft-versus-host disease (cGVHD), with Phase III trials ongoing in China and Ib/IIa data published in Blood demonstrating superior 12-month failure-free survival compared to existing therapies.
