KEY INCLUSION CRITERIA
Locally advanced or metastatic NSCLC1
Confirmed KRAS G12C mutation determined in tumor tissue1
Previously treated with an I-O–based regimen1*
Stable brain metastases allowed2†
KRAZATI 600 mg PO BID
Until unacceptable toxicity or disease progression1
Key exclusion criteria included history of intestinal disease or major gastric surgery likely to alter absorption of medication, inability to swallow oral medications, active brain metastases, carcinomatous meningitis, other active cancer.2
