    Dynamic monitoring of circulating tumor DNA to analyze genetic characteristics and resistance profile of lorlatinib in ALK positive previously treated NSCLC. (PubMed, Thorac Cancer)
    The dynamic changes of genomic characteristics during lorlatinib treatment revealed the mutation landscape of Chinese patients with NSCLC after ALK-TKI resistance, indicated that the resistance profile of lorlatinib were heterogeneous, which laid the foundation for subsequent treatment to overcome lorlatinib resistance.

    Lorlatinib and compound mutations in ALK+ large-cell neuroendocrine lung carcinoma: a case report. (PubMed, Cold Spring Harb Mol Case Stud)
    Despite early progression within 3 mo under crizotinib, a durable response was achieved with alectinib...Another rebiopsy revealed ALK:p.L1196M, but the tumor did not respond to brigatinib or carboplatin/pemetrexed, before stabilization under lorlatinib...Lorlatinib retained efficacy in the heavily pretreated setting, while its upfront use could possibly have prevented the stepwise emergence of compound ALK mutations. Furthermore, the disease course was more aggressive and OS shorter compared to the V2/TP53wt ALK+ lung adenocarcinoma, while crizotinib, ceritinib and brigatinib did not confer the benefit expected according to NGS results, which also underline the need for more potent drugs against ALK in the high-risk setting of neuroendocrine histology.

    Real-world circulating tumor DNA analysis depicts resistance mechanism and clonal evolution in ALK inhibitor-treated lung adenocarcinoma patients. (PubMed, ESMO Open)
    Sequential postprogression plasma profiling revealed that increased lines of ALK inhibitors can accelerate the accumulation of ALK resistance mutations and may lead to treatment-refractory compound ALK mutations. The selection for optimal first-line TKI is very important to achieve a more efficacious long-term strategy and prevent the emergence of on-target resistance, which may provide guidance for clinical decision making.

    Resistance profiles of anaplastic lymphoma kinase tyrosine kinase inhibitors in advanced non-small-cell lung cancer: a multicenter study using targeted next-generation sequencing. (PubMed, Eur J Cancer)
    The mechanisms of ALK TKI resistance were heterogeneous; ALK mutations were found in less than one-third of patients. Compound ALK mutations, which may confer lorlatinib resistance, may occur in crizotinib, ceritinib, and alectinib-resistant lung cancers.

    [VIRTUAL] Clinical utility of ctDNA for detection of EGFR, ALK, BRAFV600E alterations and resistance mutations in patients with NSCLC at failure to targeted therapy (ESMO 2021)
    In samples from EGFRm ex19/21 pts treated with 1st/2nd generation (gen.) TKI (n=51), the T790M mutation was detected in 27%; in those from pts treated with osimertinib (n=15), the C797S rate was 13%. In ALKr pts treated with crizotinib (n=17), ≥1 ALK resistance mutations were found in 12% (1 G1269A+F1174L, 1 G1202R), after 2nd gen. (n=16) in 31% (3 G1202R, 1 D1203N+F1174C, 1 T1151R) and after lorlatinib (n=16) in 13% (2 G1202R)... ctDNA is feasible in pts with NSCLC harbouring EGFRm, ALKr, BRAFV600Em for detecting driver and resistance GAs at PD, providing clinical informative for treatment selection at TKI failure in 22% of cases. Outcomes of the following therapies based on ctDNA will be presented at the congress.
