Cancer nanomedicine is defined as the application of nanotechnology and nanomaterials for the formulation of cancer therapeutics that can overcome the impediments and restrictions of traditional chemotherapeutics. Multidrug resistance (MDR) in cancer cells can be defined as a decrease or abrogation in the efficacy of anticancer drugs that have different molecular structures and mechanisms of action and is one of the primary causes of therapeutic failure. There have been successes in the development of cancer nanomedicine to overcome MDR; however, relatively few of these formulations have been approved by the United States Food and Drug Administration for the treatment of cancer. This is primarily due to the paucity of knowledge about nanotechnology and the fundamental biology of cancer cells. Here, we discuss the advances, types of nanomedicines, and the challenges regarding the translation of in vitro to in vivo results and their relevance to effective therapies.

The U.S. Food and Drug Administration (FDA) first approved amivantamab, a monoclonal epidermal growth factor receptor (EGFR)-mesenchymal--epithelial transition factor (MET) bispecific antibody, in May 2021, to treat adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with an insertion mutation in exon 20 of EGFR. The approval of amivantamab represents a targeted therapy for this subtype of advanced NSCLC. In contrast to other drugs that inhibit the tyrosine kinase activity in the protein, EGFR, amivantamab has efficacy in inhibiting EGFR and MET. In this article, we summarize the development of therapeutic drugs for NSCLC, discuss the mechanism of action of amivantamab, review data from clinical trials with amivantamab and suggest future lines of research., (Copyright 2022 Clarivate.)
