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 L576P melanoma sensitive KIT Inhibitor Dasatinib Preclinical - Cell culture Actionable In a preclinical study, Sprycel (dasatinib) inhibited MNK pathway activation and proliferation of melanoma cell lines harboring KIT L576P in culture (PMID: 29035277). 29035277
KIT L576P melanoma sensitive KIT Inhibitor Dasatinib Clinical Study Actionable In two clinical case studies, patients with Gleevec (imatinib)-melanoma that harboring KIT L576P demonstrated initial clinical benefit following treatment with Sprycel (dasatinib), however progressed after 3-4 months of treatment (PMID: 19671763). 19671763
KIT L576P melanoma sensitive SEL201 Preclinical - Cell line xenograft Actionable In a preclinical study, SEL201 inhibited MNK pathway signaling and growth of melanoma cells harboring KIT L576P in culture, and suppressed tumor metastasis in xenograft models (PMID: 29035277). 29035277
KIT L576P melanoma sensitive KIT Inhibitor Bevacizumab + Sorafenib Clinical Study Actionable In a clinical case study, a melanoma patient harboring KIT L576P demonstrated sensitivity to the combination treatment of Nexavar (sorafenib) and Avastin (bevacizumab), resulting in a partial response for 8 months (PMID: 25363205). 25363205
KIT L576P melanoma no benefit KIT Inhibitor Imatinib Clinical Study Actionable In a clinical case report, Gleevec (imatinib mesylate) treatment resulted in initial tumor reduction followed by disease progression in a patient with metastasized labial melanoma harboring KIT L576P (PMID: 20372153). 20372153
