Eligibility Criteria

        Inclusion Criteria:

          -  Histologically confirmed diagnosis of colorectal carcinoma with KRAS G12C mutation in
             tumor tissue.

          -  Prior receipt of 1st line treatment in advanced CRC with a fluoropyrimidine-based
             chemotherapy regimen containing either oxaliplatin or irinotecan, and radiographically
