    Impact of EML4-ALK fusion variant and co-occurring TP53 mutation on treatment duration of first-line next-generation ALK TKIs in ALK fusion+ NSCLC. (ASCO 2023)
    Pts with advanced/metastatic NSCLC who were ALK+ in circulating tumor DNA by Guardant360 (G360) liquid biopsy test from Jan 1, 2018, to Dec 31, 2021, and received 1L monotherapy with a next-generation ALK TKI (alectinib, brigatinib, ceritinib, lorlatinib) were identified in the Guardant INFORM clinical-genomics database. Among pts with NSCLC and ALK fusion, co-occurrence of EML4-ALK V3 and TP53 mutation is common and associated with poor prognosis and high risk of early discontinuation of 1L treatment with a next-generation ALK TKI, most likely due to disease progression. Additional novel or combination therapies are warranted for this subpopulation. >a 117 pts had data for both TP53 and EML4-ALK V1 or V3.
