Molecular Profile BRAF V600E
Therapy Erlotinib + Vemurafenib
Indication/Tumor Type colorectal cancer
Response Type sensitive

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.

BRAF V600E colorectal cancer sensitive Erlotinib + Vemurafenib Phase Ib/II Actionable In a Phase Ib/II trial (EVICT), the combination of Zelboraf (vemurafenib) and Tarceva (erlotinib) resulted in an overall response rate of 16% (5/31; 5 partial responses), a clinical benefit rate of 65% (20/31), a median progression-free survival of 3.9 months, and a median overall survival of 6.3 months in patients with colorectal cancer harboring BRAF V600E (PMID: 36638198). 36638198
BRAF V600E colorectal cancer sensitive Erlotinib + Vemurafenib Preclinical - Cell line xenograft Actionable In a preclinical study, Zelboraf (vemurafenib) treatment in combination with Tarceva (erlotinib) enhanced tumor growth inhibition and increased survival in a cell line xenograft model of colorectal cancer harboring BRAF V600E compared to either agent alone (PMID: 22180495). 22180495
BRAF V600E colorectal cancer sensitive Erlotinib + Vemurafenib Preclinical - Cell line xenograft Actionable In a preclinical study, the combination of Zelboraf (vemurafenib) and Tarceva (erlotinib) resulted in improved inhibition of tumor growth in BRAF V600E mutant human colon cancer cell line xenograft models compared to either drug as monotherapy (PMID: 22448344). 22448344
