Molecular Profile EML4 - ALK ALK L1196M
Therapy Crizotinib
Indication/Tumor Type Advanced Solid Tumor
Response Type resistant

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.

EML4 - ALK ALK L1196M Advanced Solid Tumor resistant Crizotinib Preclinical - Cell culture Actionable In a preclinical study, transformed cells expressing ALK L1196M in the context of EML4-ALK were resistant to Xalkori (crizotinib) in culture (PMID: 22277784). 22277784
EML4 - ALK ALK L1196M Advanced Solid Tumor resistant Crizotinib Preclinical - Cell culture Actionable In a preclinical study, transformed cells expressing EML4-ALK with ALK L1196M demonstrated resistance to Xalkori (crizotinib) in culture (PMID: 25727400). 25727400
EML4 - ALK ALK L1196M Advanced Solid Tumor resistant Crizotinib Preclinical - Cell culture Actionable In a preclinical study, transformed cells expressing ALK L1196M in the context of EML4-ALK were insensitive to Xalkori (crizotinib) as demonstrated by a lack of growth inhibition and Alk phosphorylation in culture (PMID: 26698910). 26698910
