a Study to Evaluate the Safety and Efficacy of D-1553 Combined With IN10018 in KRAS G12C Mutant Solid Tumors

Summary

This is a phase 1b/II, open-label study to evaluate the safety, tolerability, pharmacokinetics and antitumor activities of D-1553 in combination with IN10018 in subjects with locally advanced or metastatic solid tumor with KRAS G12C mutation.

Inclusion Criteria:

1. Men or women aged ≥ 18 years at the time of signing the informed consent form.
2. Subjects with pathologically confirmed locally advanced or metastatic solid tumors.
3. Confirmed positive KRAS G12C mutation in tumor tissue or other biospecimens (only for phase1b) containing cancer cells or DNA.
4. Tumor types in different phases and cohorts: 1) Phase 1b: subjects with locally advanced or metastatic solid tumors who have progressed on or failed in standard therapy, and no standard treatment is available. 2) Phase II Cohort A: subjects with locally advanced or metastatic CRC. 3) Phase II Cohort B: subjects with locally advanced or metastatic NSCLC. 4) Phase 2 Cohort C: subjects with other locally advanced or metastatic solid tumors.
5. Has measurable lesions at baseline according to RECIST 1.1 criteria.
6. Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
7. Adequate bone marrow, liver, renal, and coagulation function within 7 days prior to the first dose.
