Abstract Text Lorlatinib is currently the most advanced, potent and selective anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor for the treatment of ALK-positive non-small cell lung cancer in the clinic; however, diverse compound ALK mutations driving therapy resistance emerge. Here, we determine the spectrum of lorlatinib-resistant compound ALK mutations in patients, following treatment with lorlatinib, the majority of which involve ALK G1202R or I1171N/S/T. We further identify structurally diverse lorlatinib analogs that harbor differential selective profiles against G1202R versus I1171N/S/T compound ALK mutations. Structural analysis revealed increased potency against compound mutations through improved inhibition of either G1202R or I1171N/S/T mutant kinases. Overall, we propose a classification of heterogenous ALK compound mutations enabling the development of distinct therapeutic strategies for precision targeting following sequential tyrosine kinase inhibitors.

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.
