Drug Name | Trade Name | Synonyms | Drug Classes | Drug Description |
---|---|---|---|---|
Cetuximab | Erbitux | IMC-C225 | EGFR Antibody 60 | Erbitux (cetuximab) is a monoclonal antibody directed against EGFR, which inhibits signal transduction and cell proliferation (PMID: 28695301). Erbitux (cetuximab) is FDA approved for use in head and neck squamous cell carcinoma and KRAS wild-type, EGFR positive colorectal cancer (FDA.gov). |
Irinotecan | Camptosar | CPT-11 | TOPO1 inhibitor 11 | Camptosar (irinotecan) inhibits Topoisomerase-I activity, resulting in inhibition of DNA replication, and potentially leading to cell death and is indicated as a component of first-line therapy in combination with 5-fluorouracil and leucovorin for patients with metastatic or recurrent colorectal carcinoma (FDA.gov). |
Vemurafenib | Zelboraf | RO5185426|PLX4032 | RAF Inhibitor (Pan) 28 | Zelboraf (vemurafenib) inhibits BRAF V600E, wild-type BRAF, ARAF, and CRAF (PMID: 20179705), which may result in an inhibition of the MAPK signaling pathway resulting in a reduction of tumor cell proliferation (PMID: 20823850). Zelboraf (vemurafenib) is FDA approved for BRAF V600E-mutant melanoma and for BRAF V600-positive Erdheim-Chester disease (FDA.gov). |

BRAF V600E | colorectal cancer | sensitive | Cetuximab + Irinotecan + Vemurafenib | Phase II | Actionable | In a Phase II trial (SWOG1406), addition of Zelboraf (vemurafenib) to Camptosar (irinotecan) plus Erbitux (cetuximab) improved progression-free survival (4.4 vs. 2.0 mo, HR 0.50, p=0.001), response rate (17% vs 4%, p=0.05), and disease control rate (67% vs. 22%, p<0.001) in patients with metastatic colorectal cancer harboring BRAF V600E (PMID: 33356422; NCT02164916). | 33356422 |
BRAF V600E | colorectal cancer | sensitive | Cetuximab + Irinotecan + Vemurafenib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Zelboraf (vemurafenib) treatment in combination with Erbitux (cetuximab) and Camptosar (irinotecan) enhanced tumor growth inhibition and increased survival in a cell line xenograft model of colorectal cancer harboring BRAF V600E (PMID: 22180495). | 22180495 |
BRAF V47_M438del BRAF V600E | colon adenocarcinoma | predicted - resistant | Cetuximab + Irinotecan + Vemurafenib | Case Reports/Case Series | Actionable | In a clinical case study, BRAF V47_M438del (reported as deletion of exons 2-10) was identified in the post-progression biopsy of a patient with colon adenocarcinoma harboring BRAF V600E, who previously responded to the combination of Captosar (irinotecan), Erbitux (cetuximab), and Zelboraf (vemurafenib) (PMID: 32669268). | 32669268 |
