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.

FLT3 exon 14 ins JAK3 V722I hematologic cancer sensitive Gilteritinib + Ruxolitinib Preclinical - Cell culture Actionable In a preclinical study, the combination of Xospata (gilteritinib) and Jakafi (ruxolitinib) inhibited growth of transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer resistant Midostaurin Preclinical - Cell culture Actionable In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Rydapt (midostaurin) in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer resistant Gilteritinib Preclinical - Cell culture Actionable In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Xospata (gilteritinib) in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer resistant Ruxolitinib Preclinical - Cell culture Actionable In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Jakafi (ruxolitinib) in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer resistant Tofacitinib Preclinical - Cell culture Actionable In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Xeljanz (tofacitinib) in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer sensitive Midostaurin + Tofacitinib Preclinical - Cell culture Actionable In a preclinical study, the combination of Rydapt (midostaurin) and Xeljanz (tofacitinib) inhibited cell growth and downstream signaling of transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I hematologic cancer decreased response Pacritinib Preclinical - Cell culture Actionable In a preclinical study, Vonjo (pacritinib) treatment decreased cell proliferation and Akt and Erk phosphorylation, but did not fully inhibit Stat5 phosphorylation in transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I and was less effective compared to treatment with the combination of a FLT3 inhibitor and a JAK inhibitor in culture (PMID: 33149267). 33149267
FLT3 exon 14 ins JAK3 V722I acute myeloid leukemia predicted - resistant Sorafenib Case Reports/Case Series Actionable In a clinical case study, a patient with acute myeloid leukemia harboring a FLT3-ITD mutation treated with Nexavar (sorafenib) was found to have acquired a JAK3 V722I mutation with a variant allele frequency of 49% upon relapse (PMID: 33149267). 33149267
