Molecular Profile ERBB2 A775_G776insYVMA
Therapy Ado-trastuzumab emtansine
Indication/Tumor Type lung non-small cell carcinoma
Response Type sensitive


  • 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.

ERBB2 A775_G776insYVMA lung non-small cell carcinoma sensitive Ado-trastuzumab emtansine Case Reports/Case Series Actionable In a Phase II trial, Kadcyla (ado-trastuzumab emtansine) treatment demonstrated limited efficacy in patients with relapsed non-small cell lung cancer harboring ERBB2 (Her2) mutations, resulting in a partial response in 20% (1/5) and stable disease in 60% (3/5) of patients harboring ERBB2 (HER2) A775_G776insYVMA (PMID: 29313813). 29313813
ERBB2 A775_G776insYVMA lung non-small cell carcinoma sensitive Ado-trastuzumab emtansine Preclinical - Pdx Actionable In a preclinical study, treatment with Kadcyla (ado-trastuzumab emtansine) resulted in tumor growth inhibition and tumor regression of patient derived xenograft (PDX) models harboring ERBB2 A775_G776insYVMA, but to a lesser degree than treatment with Pyrotinib (PMID: 30596880; NCT02535507). 30596880
