Mechanism Description Using complementary approaches in multiple models, including a MYC-amplified patient-derived cell line and xenograft (LUAD-0006), we established that MYC overexpression induces broad ROS1-TKI resistance. Pharmacologic inhibition of ROS1 combined with MYC knockdown were essential to completely suppress LUAD-0006 cell proliferation compared with either treatment alone. We interrogated cellular signaling in ROS1-TKI-resistant LUAD-0006 and discovered significant differential regulation of targets associated with cell cycle, apoptosis, and mitochondrial function.

Mechanism Description The L1196M gatekeeper mutation is the most common ALk mutation conferring crizotinib resistance while other resistance mutations include I1171T, F1174C, G1202R, S1206Y, and G1269A. The drugs bind to an inactive enzyme and they do not extend past the gatekeeper into the back pocket of the drug binding site. By applying a base-pair specific error-weighted mutation calling algorithm (BASCA) that we developed for this assay, genomic DNA analysis from thirteen relapsed patients revealed three known crizotinib resistance mutations, C1156Y, L1196M and G1269A. Our assay demonstrates robust and sensitive detection of ALk kinase mutations in NSCLC tumor samples and aids in the elucidation of resistance mechanisms pertinent to the clinical setting. Non-small cell lung cancers (NSCLC) harboring anaplastic lymphoma kinase (ALk) gene rearrangements invariably develop resistance to the ALk tyrosine kinase inhibitor (TkI) crizotinib. In particular, ceritinib effectively inhibits ALk harboring L1196M, G1269A, I1171T and S1206Y mutations, and a co-crystal of ceritinib bound to ALk provides structural bases for this increased potency. Acquired resistance can occur through failure of drug delivery to the target, as in isolated central nervous system (CNS) progression, or by selection of biological variants during TkI exposure.

Mechanism Description Three patients harbored secondary ALk mutations, including one patient with both mutations: L1196M (n = 2) and G1269A (n = 2). Genetic changes associated with crizotinib resistance are heterogeneous in ALk-rearranged NSCLC patients who respond to crizotinib and subsequently develop resistance. ALk-dependent mechanisms include gatekeeper (L1196M) or other mutations such as C1156Y and G1269A in the ALk kinase domain and ALk copy number gain.

Mechanism Description The L1196M gatekeeper mutation is the most common ALk mutation conferring crizotinib resistance while other resistance mutations include I1171T, F1174C, G1202R, S1206Y, and G1269A. The drugs bind to an inactive enzyme and they do not extend past the gatekeeper into the back pocket of the drug binding site. By applying a base-pair specific error-weighted mutation calling algorithm (BASCA) that we developed for this assay, genomic DNA analysis from thirteen relapsed patients revealed three known crizotinib resistance mutations, C1156Y, L1196M and G1269A. Our assay demonstrates robust and sensitive detection of ALk kinase mutations in NSCLC tumor samples and aids in the elucidation of resistance mechanisms pertinent to the clinical setting. Acquired resistance can occur through failure of drug delivery to the target, as in isolated central nervous system (CNS) progression, or by selection of biological variants during TkI exposure. In contrast, cells expressing either the C1156Y or L1196M mutant form manifested a markedly reduced sensitivity to the drug.

Mechanism Description Three patients harbored secondary ALk mutations, including one patient with both mutations: L1196M (n = 2) and G1269A (n = 2). Genetic changes associated with crizotinib resistance are heterogeneous in ALk-rearranged NSCLC patients who respond to crizotinib and subsequently develop resistance. In 1 of the 15 cases examined, ALk FISH revealed high-level gene amplification. No ALk resistance mutations were found in this specimen, so it appears that high-level amplification of the wild-type ALk fusion gene is sufficient to cause resistance.

Mechanism Description In contrast, cells expressing either the C1156Y or L1196M mutant form manifested a markedly reduced sensitivity to the drug (23836314; 20979470). By applying a base-pair specific error-weighted mutation calling algorithm (BASCA) that we developed for this assay, genomic DNA analysis from thirteen relapsed patients revealed three known crizotinib resistance mutations, C1156Y, L1196M and G1269A. Our assay demonstrates robust and sensitive detection of ALk kinase mutations in NSCLC tumor samples and aids in the elucidation of resistance mechanisms pertinent to the clinical setting.

Mechanism Description The L1196M gatekeeper mutation is the most common ALk mutation conferring crizotinib resistance while other resistance mutations include I1171T, F1174C, G1202R, S1206Y, and G1269A. The drugs bind to an inactive enzyme and they do not extend past the gatekeeper into the back pocket of the drug binding site. Non-small cell lung cancers (NSCLC) harboring anaplastic lymphoma kinase (ALk) gene rearrangements invariably develop resistance to the ALk tyrosine kinase inhibitor (TkI) crizotinib. In particular, ceritinib effectively inhibits ALk harboring L1196M, G1269A, I1171T and S1206Y mutations, and a co-crystal of ceritinib bound to ALk provides structural bases for this increased potency. Acquired resistance can occur through failure of drug delivery to the target, as in isolated central nervous system (CNS) progression, or by selection of biological variants during TkI exposure.

Mechanism Description An acquired mutation in the MET kinase domain, D1228N, was found at time of progression on crizotinib in a patient with MET exon 14 skipping. Crystal structures of type I MET inhibitors bound to the MET kinase domain show an important binding interaction with the Y1230 residue, with D1228 playing a role in stabilizing the conformation of the activation loop. Therefore, in addition to intrinsic transforming activity, disruption of the drug binding interaction between type I inhibitors and the MET kinase domain is hypothesized to underlie the mechanism of resistance of these specific mutations.

Mechanism Description There is a C to G mutation (asterix) in codon 3522 in exon 23 resulting in the F1174L mutation. When present in cis with an ALk translocation, this mutation (also detected in neuroblastomas) causes an increase in ALk phosphorylation, cell growth and downstream signaling. Furthermore, the F1174L mutation inhibits crizotinib mediated downregulation of ALk signaling and blocks apoptosis in RANBP2-ALk Ba/F3 cells.
