Production capability expanded significantly from 5,000L to 24,000L. With the NRDL coverage, we more than doubled the sales of Tyvyt with even higher volume growth. We kept advancing our valuable assets rapidly in China and globally, with six NDAs submitted, four NDAs approved, five assets in Phase 3 or pivotal Phase 2 stage, and 14 assets in the early clinical stage. We also accelerated our global footprint with six assets under global development and a series of international collaborations achieved. More importantly, we've upgraded our R&D platform to strive toward global innovation for the next stage."

"With the conclusion of the ninth year since incepted, we are now starting the final year of our first decade. Up to now we have built Innovent from a biotech start up to a biopharmaceutical company with a fully integrated functional platform. However, this is just a start. Our journey to excellence is still in the infancy stage. Heading into the next decade, we are committed to moving Innovent to become a global innovative biopharmaceutical company, capturing the substantial potential of the rising innovative drug market both in China and globally, as well as and delivering tremendous value for our patients, employees, and shareholders."
