ABSTRACT

We have recently developed a novel PEG-block-oligocholic acid based micelles system for efficient anticancer drug delivery. This nanocarrier has several optimized properties: (1) biocompatible, stealth and stable drug-encapsulated nanoformulations with high drug loading capacity, take advantage of the enhanced permeability and retention effect (EPR) to target tumor sites; (2) the modular design and step-wise synthesis allows introducing functional groups and building blocks at the specific site of telodendrimers to optimize the drug loading properities; (3) the optimized size (20-100 nm) of the nanocarriers lowers liver and lung uptake while ensuring the deep penetration of nanotherapeutics into the tumor mass; (4) the decoration with tumor cell specific binding ligand or antibodies to concentrate the nanocarrier in tumor sites and enhance anti-tumor effects. The paclitaxel loaded telodendrimer micellar formulation exhibits superior toxicity and efficacy profile in xenograft models when compared to Taxol® and Abraxane®. It was well tolerated and exhibited significant anticancer effects in the canine clinic trials Phase I and II.

An IND has been filed with FDA for evaluation of this paclitaxel nanoformulaiton in human cancer patients in clinic trial.
