Profile Name FGFR2 H167_N173del
Gene Variant Detail

FGFR2 H167_N173del (gain of function)

Relevant Treatment Approaches

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.

FGFR2 H167_N173del intrahepatic cholangiocarcinoma predicted - sensitive Debio 1347 Case Reports/Case Series Actionable In a clinical study, Debio 1347 treatment resulted in durable partial response of 11 months in 2 patients with intrahepatic cholangiocarcinoma harboring FGFR2 H167_N173del (J Clin Oncol 38, 2020 (suppl 4; abstr 567)). detail...
FGFR2 H167_N173del intrahepatic cholangiocarcinoma predicted - sensitive Debio 1347 Case Reports/Case Series Actionable In a Phase I trial, Debio 1347 treatment led to 51% tumor reduction and a progression-free survival of 13 months in an intrahepatic cholangiocarcinoma patient harboring FGFR2 H167_N173del, which was consistent with inhibition of growth in an intrahepatic cholangiocarcinoma cell line expressing FGFR2 H167_N173del in culture (PMID: 33926920; NCT01948297). 33926920
FGFR2 H167_N173del intrahepatic cholangiocarcinoma predicted - sensitive Futibatinib Preclinical - Cell culture Actionable In a preclinical study, Lytgobi (futibatinib) inhibited growth of an intrahepatic cholangiocarcinoma cell line expressing FGFR2 H167_N173del in culture (PMID: 33926920). 33926920
FGFR2 H167_N173del marginal zone lymphoma predicted - sensitive Debio 1347 Preclinical - Cell culture Actionable In a clinical case study, Debio 1347 treatment in a marginal zone lymphoma patient harboring FGFR2 H167_N173del, who had previously been treated with several lines of therapy, led to a partial response and 36% decrease in tumor burden associated with lymphadenopathy and lung and liver lesions at 16 weeks, with continued response after 7 months (PMID: 33926920). 33926920
FGFR2 H167_N173del cholangiocarcinoma sensitive Infigratinib Preclinical - Cell culture Actionable In a preclinical study, Truseltiq (infigratinib) decreased viability of a cholangiocarcinoma cell line expressing FGFR2 H167_N173del in culture (PMID: 37964396). 37964396
