Abstract:The third generation EGFR tyrosine kinase inhibitors (TKIs), like Osimertinib, target classical activating EGFR mutations containing T790M resistance mutation. However, the exon 20 insertion (Ex20Ins), the third most common EGFR mutations in entire NSCLC, still lacks its therapeutic option. Recently, Robichaux JP et al., showed that Poziotinib, which had been developed as a second-generation EGFR TKI, had efficacy for the EGFR and Her2 Ex20Ins compared to EGFR T790M. Here, we developed inhibitors, structurally… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
