Recent Developments in Tyrosine Kinase Inhibitor-based Nanotherapeutics for EGFR-resistant Non-small Cell Lung Cancer.

ABSTRACT

The advent of drug resistance in response to epidermal growth factor receptor (EGFR)- tyrosine kinase inhibitor (TKI) targeted therapy represents a serious challenge in the management of non-small cell lung cancer (NSCLC). These acquired resistance mutations, attributed to several advanced EGFR mutations and, necessitated the development of new-generation TKIs. Nanomedicine approaches provide a plausible way to address these problems by providing targeted delivery and sustained release, which have demonstrated success in preclinical trials. This review article provides a summary of nano-formulations designed for EGFR-TKI-resistant NSCLC, highlighting their efficacy in both in vitro and in vivo models. These findings reveal insights into the design of nanoparticles and multifunctional nanosystems, offering a potential avenue for efficacious treatment of EGFR-TKIresistant NSCLC.
