Title Pulse Afatinib for ERBB2 Exon 20 Insertion-Mutated Lung Adenocarcinomas.
URL
Abstract Text Genomic aberrations involving the erb-b2 receptor tyrosine kinase 2 gene (ERBB2) are driver oncogenes in approximately 2% of lung adenocarcinomas. However, the use of daily dosing of ERBB2 tyrosine kinase inhibitors (TKIs)-including afatinib-has been fraught with plasma concentrations that barely achieve preclinical model inhibition, significant patient-reported toxicities, and limited clinical activity. We hypothesized that alternative dosing strategies could improve tolerability and efficacy.We profiled lung cancer cell lines against TKIs and retrospectively evaluated the toxicity of and response to pulse afatinib (280 mg once weekly) in lung cancers with ERBB2 mutations.An ERBB2 exon 20 insertion-mutated lung cancer cell line had a 50% inhibitory concentration in response to afatinib that was higher than the reported plasma concentration of afatinib, 40 mg daily. Three patients with advanced ERBB2-mutated lung adenocarcinomas were treated with off-label pulse afatinib. The 280-mg weekly dose was well tolerated with no reported rash and minimal diarrhea. One TKI-naive patient achieved a partial response for 5 months and another achieved stable disease for 11 months.Pulse afatinib at a weekly dosing scheme induced antitumor activity in ERBB2 exon 20 insertion-mutated lung adenocarcinomas. Future clinical trials of alternative dosing schemes of ERBB TKIs as monotherapy or in combination with other therapies are warranted for ERBB2-mutated tumors.

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.
