GlaxoSmithKline plc (GSK, NYSE: GSK) has announced a strategic licensing agreement with Jiangsu Chia Tai Tianqing Pharmaceutical Co., Ltd. (CTTQ), a wholly-owned subsidiary of Sino Biopharmaceutical Ltd (HKG: 1177), for the commercialization of bepirovirsen in China—the world’s largest hepatitis B market with approximately 70 million chronic carriers.
Partnership Structure & Operational Framework
| Party | Responsibilities | Revenue Recognition |
|---|---|---|
| CTTQ (Sino Bio Subsidiary) | Import, distribution, hospital access, promotion, non-promotional activities | 100% of Chinese sales revenue |
| GlaxoSmithKline | Regulatory filings, quality control, pharmacovigilance, global medical strategy | Supply revenue from product sales to CTTQ |
The 5.5-year collaboration leverages CTTQ’s established commercial infrastructure—reaching over 6,000 hospitals nationwide—while maintaining GSK’s oversight of regulatory and quality standards. Under the agreement, Sino Biopharmaceutical will purchase bepirovirsen from GSK under predetermined supply terms, with all Chinese market sales recorded as Sino Bio revenue.
