Therapy Name Encorafenib
Synonyms
Therapy Description

Braftovi (encorafenib) is an inhibitor of Raf kinase with selective activity against BRAF V600E, resulting in growth inhibition (PMID: 24864047). Braftovi (encorafenib) in combination with Mektovi (binimetinib) is FDA approved for use in patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation (FDA.gov).

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.

BRAF L597S melanoma sensitive Encorafenib Preclinical - Cell culture Actionable In a preclinical study, Braftovi (encorafenib) inhibited ERK activation and proliferation of melanoma cell lines harboring BRAF L597S in culture (PMID: 29903896). 29903896
BRAF mutant melanoma sensitive Encorafenib Phase I Actionable In a Phase I trial, Encorafenib (LGX818) treatment resulted in an overall response rate (ORR) of 60% (15/25) and a median progression-free survival (mPFS) of 12.4 months in BRAF inhibitor-naïve melanoma patients harboring BRAF mutations, and an ORR of 22% (6/29) and mPFS of 1.9 months in BRAF inhibitor-pretreated patients (PMID: 28611198; NCT01436656). 28611198
BRAF G469V melanoma no benefit Encorafenib Preclinical - Cell culture Actionable In a preclinical study, Braftovi (encorafenib) did not inhibit ERK phosphorylation or proliferation of a melanoma cell line harboring BRAF G469V (PMID: 29903896). 29903896
BRAF R239Q BRAF L597S melanoma sensitive Encorafenib Preclinical - Pdx & cell culture Actionable In a preclinical study, Braftovi (encorafenib) inhibited ERK activation and proliferation of patient-derived melanoma cells harboring BRAF L597S, as well as BRAF R239Q, in culture, and delayed tumor growth and induced shrinkage in 8% (1/12) of tumors in a melanoma patient-derived xenograft (PDX) model (PMID: 29903896). 29903896
BRAF V600E colorectal cancer sensitive Encorafenib Phase I Actionable In a Phase I trial, Encorafenib (LGX818) showed activity in patients with advanced metastatic colorectal cancer harboring a BRAF V600E mutation, resulting in a median progression-free survival of 4 months and a best response of stable disease in 66.7% (12/18) (Ann Oncol (2014) 25 (suppl 4): iv182-iv183). detail...
