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.

KIT exon13 gastrointestinal stromal tumor sensitive Imatinib + MK2206 Preclinical - Cell culture Actionable In a preclinical study, the combination of Gleevec (imatinib) and MK2206 demonstrated synergy in inhibiting growth of a gastrointestinal stromal tumor cell line harboring a KIT exon 13 mutation in culture (PMID: 27370604). 27370604
KIT exon13 melanoma sensitive Nilotinib Phase II Actionable In a Phase II trial, Tasigna (nilotinib) resulted in an overall response rate of 26.2% (11/41), which included a partial response in 7.7% (1/13) of melanoma patients harboring KIT exon 13 mutations (PMID: 28327988). 28327988
KIT exon13 melanoma sensitive Nilotinib Phase II Actionable In a Phase II trial, Tasigna (nilotinib) treatment resulted in complete response in 5% (1/19) and partial response in 21% (4/19) of melanoma patients harboring KIT exon 11 or exon 13 mutations (PMID: 28843487; NCT01168050). 28843487
KIT exon13 gastrointestinal stromal tumor sensitive Adavosertib + Avapritinib Preclinical - Cell culture Actionable In a preclinical study, the combination of Adavosertib (MK-1775) and Ayvakit (avapritinib) synergized to inhibit growth of a gastrointestinal stromal tumor cell line harboring a KIT exon 13 mutation in culture (PMID: 33320833). 33320833
KIT exon13 melanoma not predictive Pembrolizumab Clinical Study Actionable In a retrospective analysis, real-world treatment with either Keytruda (pembrolizumab) or Toripalimab (JS001) resulted in a median disease-free survival of 33 months in melanoma patients harboring KIT mutations in either exon 11 (64.8%), exon 13 (17.6%), or exon 17 (17.6%) compared to 32 months in patients with wild-type BRAF, NRAS, and KIT (p=0.200) (PMID: 37403699). 37403699
