    Biomarker:HER-2 mutation
    Cancer:Non Small Cell Lung Cancer

    NCCN
    Excerpt:
    The NCCN NSCLC panel does not recommend single-agent therapy with trastuzumab or afatinib (both for ERBB2 mutations), because response rates are lower and treatment is less effective when these agents are used for patients with ERBB2 mutations.

    Activity of Afatinib in Heavily Pretreated Patients With ERBB2 Mutation-Positive Advanced NSCLC: Findings From a Global Named Patient Use Program

    Excerpt:
    Twenty-eight heavily pretreated patients in the named patient use program had a documented ERBB2 mutation by local testing. Median time-to-treatment failure (TTF; time from treatment initiation to discontinuation for any reason) was 2.9 months; eight patients (29%) had TTF greater than 1 year. Objective response rate was 19% (3 of 16 patients with response data achieved partial response) and disease control rate (DCR) was 69% (11 of 16).
