    Diverse resistance mechanisms to the third-generation ALK inhibitor lorlatinib in ALK-rearranged lung cancer. (PubMed, Clin Cancer Res)
    This study shows that mechanisms of resistance to lorlatinib are diverse and complex, requiring new therapeutic strategies to tailor treatment upon disease progression.

    [VIRTUAL] Longitudinal circulating tumor DNA (ctDNA) analysis predicts response and reveals the resistance mechanisms of ensartinib in ALK+ NSCLC patients (pts) progressed on crizotinib: Updated analysis of a phase II clinical trial (AACR-II 2020)
    Consistent with previous reports, ensartinib showed high clinical efficacy. Longitudinal ctDNA analysis could be a powerful tool in predicting treatment outcomes and revealing resistant mechanisms of ensartinib. We observed G1269A, G1202R and E1210K as the major resistant mutations to ensartinib.
