Gross profit margin of product sales was 87.3%,with an increase of 7.4% compared with 79.9% for the same period of last year. This was primarily due to the notable manufacturing efficiency improvement as the 6*3000L stainless steel bioreactor production lines were put in use since the fourth quarter of 2020.

R&D expenses was increased by 29.0% to RMB1,042.1 million,which were mainly put into use of clinical trial development of more late-stage and prioritized pipeline assets in China and globally.
