Summary

The study is divided into 2 cohorts, Cohort 1 is patients with KRASG12C mutated non-small cell lung cancer who have failed standard therapy or no standard therapy and have been treated with KRASG12C inhibitor; Cohort 2 is patients with KRASG12C mutated solid tumors (except non-small cell lung cancer) who have failed standard therapy or have no standard therapy and have been treated with KRASG12C inhibitor. Each cohort consists of two stages, and 10 subjects are planned to be enrolled in the first stage of each cohort. According to the preliminary efficacy and safety data, each party will discuss and decide whether to continue the second stage. Twenty to fifty subjects were planned to be enrolled in Stage II of each cohort. A total of 20-120 subjects were enrolled.

Screened eligible subjects received GH21 in combination with D-1553 in 21-day cycles until the investigator considered the subject no longer benefiting, or the subject developed intolerable toxicity, or the subject withdrew consent, or the subject died, or was lost to follow-up, or received a new anticancer treatment, whichever came first.
