Relevant Treatment Approaches

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 CDKN2A loss NRAS G12V melanoma predicted - resistant Cobimetinib + Vemurafenib Case Reports/Case Series Actionable In a clinical case study, a melanoma patient harboring BRAF V600E experienced progressive disease after a response to combination therapy with Zelboraf (vemurafenib) and Cotellic (cobimetinib), likely due to acquisition of NRAS G12V and a loss of one copy of CDKN2A (PMID: 34376578). 34376578
BRAF V600E CDKN2A loss NRAS G12V melanoma predicted - sensitive Palbociclib + Trametinib Preclinical - Pdx Actionable In a preclinical study, combination treatment with Ibrance (palbociclib) and Mekinist (trametinib) led to inhibition of tumor growth in a patient-derived xenograft (PDX) model of melanoma harboring BRAF V600E, NRAS G12V, and CDKN2A copy number loss (PMID: 34376578). 34376578
BRAF V600E CDKN2A loss NRAS G12V melanoma predicted - sensitive Palbociclib + Ulixertinib Preclinical - Pdx Actionable In a preclinical study, combination treatment with Ibrance (palbociclib) and Ulixertinib (BVD-523) led to inhibition of tumor growth in a patient-derived xenograft (PDX) model of melanoma harboring BRAF V600E, NRAS G12V, and CDKN2A copy number loss (PMID: 34376578). 34376578
