Title:

A study to explore the effects of cetuximab alone or in combination with irinotecan in patients with an abnormal gene (KRAS) in their colon cancer cells.

Excerpt:
...Prior confirmation of tumour KRAS status as either KRAS WT (with no mutations or changes in BRAF, NRAS, PIK3CA exon20) OR KRAS G13D mutation,6. ...

Title:

Colon cancer-derived oncogenic EGFR G724S mutant identified by whole genome sequence analysis is dependent on asymmetric dimerization and sensitive to cetuximab

Excerpt:
...cetuximab treatment was ineffective for the tumors driven by HCT8, which is consistent with the previous findings that KRAS-mutant tumors are insensitive to cetuximab (Figure  2C)….
