Adopting a combinatory and complementary R&D strategy, we aim to initiate multiple clinical trials to develop therapies that will complement existing treatments and address treatment gaps in some of the most prevalent oncological indications. This year, we will continue to execute on our strategy of further developing our commercial infrastructure in China and the Asia Pacific region, in an effort to expedite the commercialization of our lead asset; and continue to enrich our pipeline and strengthen our core competitiveness by in-licensing additional highly promising assets. In 2021, we will present our research results at major international conferences, to further build a solid foundation for a first-in-class commercial launch of our lead asset in multiple markets, and to advance several pre-clinical novel assets  into clinical stage. Honoring our commitment to patients and pursuing our mission as a member of the healthcare community, we will strive to bring hope to patients and deliver greater return to our investors," added Dr. Jay Mei.
