According to Figures 3A-3C, a simple description of the correlation between EGFR expression levels and therapeutic efficacy is as follows:
In the 33 patients who crossed over to receive MRG003 treatment, the investigator-assessed overall response rate (ORR) was 21.2% (95% CI: 9.0%, 38.9%), the disease control rate (DCR) was 75.8% (95% CI: 57.7%, 88.9%), and the duration of response (DoR) was 6.31 months (95% CI: 2.17, 7.85).
