BeiGene Ltd.Zanubrutinib global sales grew from $1B to $3.9B, with US market driving 71.8% of revenue, indicating strong product demand.

BeiGene President and Global Head of R&D Wang Lai reviewed the development journey of the company’s core drug, the BTK inhibitor zanubrutinib, at the inaugural Great Nation New Drug Global Conference. Wang said that in 2017 and 2018 the company launched two global head-to-head Phase III trials, investing nearly all its funds at the time in what was truly a do-or-die gamble. Zanubrutinib was first approved in the United States in 2019. In 2022 a head-to-head trial proved it superior to ibrutinib in chronic lymphocytic leukemia, and after that indication was approved in the US in 2023, annual global sales topped one billion dollars that year. By 2025 total sales had reached 3.9 billion dollars, with the US market accounting for 71.8 percent of revenue. Wang noted that the company survived its first decade through sound decisions and investment. In the second phase it focused on building a global clinical development system, moving away from CROs and building its own team from 2017. Over the past two and a half years, five solid tumor programs have rapidly completed proof-of-concept and advanced to pivotal trials. From 2026, R&D will enter a third phase, relying on its own capabilities to run global large Phase III trials and introducing automation and artificial intelligence to boost efficiency.
