Efficacy assessments

TUMOR
Efficacy evaluations were performed by computed tomography or magnetic resonance imaging on baseline (within 28 days before the first dose), cycle 2 day 1, and then every 2 cycles (8 weeks) from cycle 3 day 1(whether CT or MRI is selected, the evaluation methods and parameters need to be consistent in each cycle). Response was evaluated by the investigator according to RECIST, version 1.1. The efficacy analysis was conducted in patients who have had at least one tumor evaluation, and when someone meets the partial response (PR) or complete response (CR) criteria, efficacy will be confirmed again at a subsequent time point (interval of at least 4 weeks) before CR or PR is granted.
