Molecular Profile ALK R1275Q
Therapy Crizotinib
Indication/Tumor Type neuroblastoma
Response Type conflicting


  • 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"


  • 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.

ALK R1275Q neuroblastoma conflicting Crizotinib Case Reports/Case Series Actionable In a Phase I/II trial (ADVL0912), Xalkori (crizotinib) treatment resulted in an objective response of 15% (3/20) in pediatric patients with relapsed/refractory neuroblastoma harboring ALK activating mutations or amplifications, among the 12 patients harboring ALK R1275Q, 1 achieved a complete response, 2 achieved partial responses, and 2 achieved prolonged stable diseases (PMID: 33568345; NCT00939770). 33568345
ALK R1275Q neuroblastoma conflicting Crizotinib Preclinical - Cell culture Actionable In a preclinical study, Xalkori (crizotinib) inhibited proliferation of neuroblastoma cells harboring ALK R1275Q in culture (PMID: 29907598). 29907598
ALK R1275Q neuroblastoma conflicting Crizotinib Preclinical - Cell line xenograft Actionable In a preclinical study, Xalkori (crizotinib) did not inhibit growth of neuroblastoma cells over expressing ALK R1275Q in culture, and only delayed tumor growth in cell line xenograft models (PMID: 26554404). 26554404
ALK R1275Q neuroblastoma conflicting Crizotinib Preclinical Actionable In a preclinical study, Xalkori (crizotinib) treatment resulted in decreased tumor weight in a Mycn-overexpressing neuroblastoma transgenic mouse model with ALK R1275Q (corresponds to R1279Q in mouse) and subsequent upregulation of Ret (PMID: 24811913). 24811913
