Description
12 patients with KRAS G13D mutant, metastatic colorectal cancer were treated with single agent cetuximab in a prospective phase II study. The primary endpoint of the trial was 4-month progression-free survival, with a benefit to treatment evaluated to be 50% of patients were progression free at this point. None of 12 patients achieved response by RECIST 1.1 criteria and three patients (25%) were progression-free at 4 months, with disease control rate at 6 months reaching 0%. Median PFS and OS were 1.9 (95% CI 1.7–3.8) and 7.2 months (95% CI 5.7–9.7).
