Development of Novel Neratinib and Docetaxel Core-Loaded and Trastuzumab Surface-Conjugated Nanoparticle for Treatment of HER-2 Positive Breast Cancer.

ABSTRACT: Background/Objectives: This study developed a targeted drug delivery nanoplatform for treating HER2-positive breast cancer. The nanoplatform encapsulated two hydrophobic anticancer agents, neratinib (NTB) and docetaxel (DTX), within nanoparticles (DTX+NTB-NP) functionalized for conjugation to trastuzumab to form trastuzumab-tagged nanoparticles (TRZ-NP). Trastuzumab is a HER2-specific monoclo-nal antibody that binds to HER2 receptors, blocking signal transduction and inducing an-tibody-dependent cellular cytotoxicity (ADCC). Upon receptor-mediated endocytosis, neratinib inhibits cytosolic HER2 signaling, while docetaxel disrupts mitotic cell division, collectively leading to tumor cell death. Methods: Nanoparticles were fabricated by the nanoprecipitation technique, followed
