Relevant Treatment Approaches KIT Inhibitor

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.

KIT A502_Y503dup Advanced Solid Tumor sensitive KIT Inhibitor Sunitinib Preclinical - Cell culture Actionable In a preclinical study, transformed cells expressing KIT A502_Y503dup (Y503_F504insAY) were sensitive to Sutent (sunitinib) in culture, demonstrating decreased cell proliferation (PMID: 24205792). 24205792
KIT A502_Y503dup gastrointestinal stromal tumor sensitive KIT Inhibitor Cabozantinib Preclinical - Pdx Actionable In a preclinical study, Cometriq (Cabometyx, cabozantinib) resulted in decreased tumor volume and reduced mitotic activity in a gastrointestinal stromal tumor patient derived xenograft (PDX) model harboring KIT A502_Y503dup (PMID: 27777285). 27777285
KIT A502_Y503dup gastrointestinal stromal tumor predicted - sensitive KIT Inhibitor Regorafenib Preclinical - Pdx Actionable In a preclinical study, Stivarga (regorafenib) did not significantly inhibit Kit, Erk, or Mtor signaling, but resulted in tumor growth inhibition in patient-derived xenograft (PDX) model of gastrointestinal stromal tumor harboring KIT A502_Y503dup and KIT D820E, which was established from a patient who did not respond to Gleevec (imatinib mesylate) and Sutent (sunitinib) (PMID: 29100343). 29100343
KIT A502_Y503dup Advanced Solid Tumor sensitive KIT Inhibitor Flumatinib Preclinical - Cell culture Actionable In a preclinical study, transformed cells expressing KIT A502_Y503dup (Y503_F504insAY) were sensitive to Flumatinib in culture, demonstrating decreased cell proliferation (PMID: 24205792). 24205792
KIT A502_Y503dup gastrointestinal stromal tumor resistant KIT Inhibitor Imatinib Preclinical - Pdx Actionable In a preclinical study, a gastrointestinal stromal tumor patient derived xenograft (PDX) model harboring KIT A502_Y503dup demonstrated resistance to treatment with Gleevec (imatinib), resulting in increased tumor volume (PMID: 27777285). 27777285
