KRAS G12C
Biomarker-Directed Therapies
KRAS G12C is a predictive biomarker for use of afatinib, dacomitinib, erlotinib, gefitinib, osimertinib, cetuximab, panitumumab, and sotorasib in patients.
Of the therapies with KRAS G12C as a predictive biomarker, 3 are FDA-approved and 7 have NCCN guidelines in at least one clinical setting.
Non-small cell lung carcinoma and colorectal carcinoma have the most therapies targeted against KRAS G12C or its related pathways [5].

Clinical Trials
KRAS G12C serves as an inclusion eligibility criterion in 25 clinical trials, of which 23 are open and 2 are closed. Of the trials that contain KRAS G12C as an inclusion criterion, 10 are phase 1 (9 open), 9 are phase 1/phase 2 (8 open), 3 are phase 2 (3 open), and 3 are phase 3 (3 open).
Trials with KRAS G12C in the inclusion eligibility criteria most commonly target non-small cell lung carcinoma, malignant solid tumor, colorectal carcinoma, non-squamous non-small cell lung carcinoma, and pancreatic ductal adenocarcinoma [5].
Pembrolizumab, adagrasib, docetaxel, cetuximab, and sotorasib are the most frequent therapies in trials with KRAS G12C as an inclusion criteria [5].
