Targeted Cancer Immunotherapy by Nanoparticle T Cell Engagers.

This study shows that nanoTCEs are a promising novel platform for immunotherapy in AML. CD33/CD3 nanoTCEs demonstrated specific engagement of T cells to AML cells, which induced T cell activation and AML cell killing both in vitro and in vivo. It not only circumvented the limitations of traditional T cell engagers, but also presented numerous advantages such as short production time, low cost, and superior pharmacokinetic profile. Moreover, this technology is highly customizable and can be tailored to target multiple cancer antigens simultaneously. The current findings provide a strong preclinical basis for future first-in-human clinical trials of CD33/CD3 nanoTCEs as a novel AML immunotherapy.
