Mechanism-Based Enhanced Delivery of Drug-Loaded Targeted Nanoparticles for Breast Cancer Therapy
Abstract
This Synergistic IDEA project seeks to develop a novel strategy to effectively target ErbB2-overexpressing breast cancer with anti-ErbB2 antibody coated nanogels carrying potent chemotherapeutics in combination with HSP90 inhibitors to enhance the endocytosis of ErbB2-receptor bound nanogel cargo. A successful outcome of our studies will provide a new therapeutic approach against a particularly difficult form of breast cancer and may provide a template for therapeutic targeting of other forms of breast cancer and other cancers. Success in preclinical models would also provide strong rationale for clinical translation of this technology with the ultimate goals of selective delivery of imaging and therapeutic modalities to tumors. Robust procedures for the synthesis of nanogels were developed, key structural parameters of block copolymers governing the physicochemical properties of the nanogels were identified, nanogels loaded with combination of anticancer therapeutics and methods for the preparation of ErbB2-targeted nanogels were developed, Mannose functionalized BICs provided a safe and stable platform for gene delivery to macrophages, doxorubicin-nanogels showed an efficient systemic drug delivery to human tumor xenografts.
