Partnering with GSK: Sino Biopharm Licenses Commercialization Rights for First-in-Class HBV Cure Drug On May 11, 2025, Sino Biopharm announced that its subsidiary CHIATAI TIANQING has entered an exclusive strategic partnership with GlaxoSmithKline (GSK) to accelerate the commercialization of bepirovirsen, a first-in-class antisense oligonucleotide (ASO) therapy with triple mechanism of action, in mainland China. CHIATAI TIANQING will manage import, distribution, hospital access, and all promotional activities, recognizing 100% of sales revenue, while GSK remains the Marketing Authorization Holder responsible for regulatory, quality, and global medical strategy. The initial term is 5.5 years, extendable by mutual agreement. Bepirovirsen, submitted for Chinese marketing approval in March 2026 and granted priority review, demonstrated significant functional cure rates in Phase III B-Well trials and could become the first finite-duration therapy to achieve functional cure for chronic hepatitis B—a disease affecting 75 million people in China and causing over 450,000 annual deaths.
