BRAF V600E BRAF amp | colorectal cancer | resistant | Cetuximab + Vemurafenib | Case Reports/Case Series | Actionable | In a clinical case study, a patient with BRAF V600E colorectal cancer developed progressive disease after a partial response lasting 16 weeks to Erbitux (cetuximab) and Zelboraf (vemurafenib) combination treatment, amplification of BRAF V600E was identified as an acquired alteration at the time of progression (PMID: 28951457). | 28951457 |
BRAF V600E BRAF amp | colorectal cancer | resistant | Cetuximab + Vemurafenib | Preclinical - Cell culture | Actionable | In a preclinical study, colorectal cancer cells harboring BRAF V600E that acquired BRAF V600E amplification and subsequent resistance to Erbitux (cetuximab) and Selumetinib (AZD6244) combination treatment were resistant to combination therapy consisting of Erbitux (cetuximab) and Zelboraf (vemurafenib) in culture (PMID: 27312529). | 27312529 |
