Therapy Name Cetuximab + Encorafenib
Synonyms
Therapy Description

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

Drug Name Trade Name Synonyms Drug Classes Drug Description
Cetuximab Erbitux IMC-C225 EGFR Antibody 31 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).
Encorafenib Braftovi LGX818 BRAF Inhibitor 21 Braftovi (encorafenib) is an inhibitor of Raf kinase with selective activity against BRAF V600E, resulting in growth inhibition (PMID: 24864047). Braftovi (encorafenib) is FDA approved for use in combination with Mektovi (binimetinib) in patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, and in combination with Erbitux (cetuximab) in patients with metastatic colorectal cancer with BRAF V600E(FDA.gov).

BRAF V600E rectum cancer sensitive Cetuximab + Encorafenib Guideline Actionable Braftovi (encorafenib) in combination with Erbitux (cetuximab) is included in guidelines as primary or subsequent therapy for patients with rectal cancer harboring BRAF V600E (NCCN.org). detail...
BRAF mutant colorectal cancer sensitive Cetuximab + Encorafenib Phase Ib/II Actionable In a Phase Ib/II trial, the combination therapy of Erbitux (cetuximab) and Encorafenib (LGX818) in colorectal cancer patients harboring a BRAF mutation resulted in an overall response rate of 19% (5/26), including 1 patient with a complete response and 4 patients with a partial response, and led to a median progression free survival of 3.7 months and response duration of 46 weeks (PMID: 28363909). 28363909
