Cancer Nanomedicine

Optimizing the delivery of nanomedicine to solid tumors

Grant No. PIRG08-GA-2010-276894


Recent advances in nanotechnology have offered new hope for cancer detection, prevention, and treatment. While the enhanced permeability and retention effect has served as a key rationale for using nanoparticles to treat solid tumors, it does not enable uniform delivery of these particles to all regions of tumors in sufficient quantities. This heterogeneous distribution of therapeutics is a result of physiological barriers presented by the abnormal tumor vasculature and interstitial matrix. These barriers are in large part responsible for the modest survival benefit offered in many cases by clinically approved nanotherapeutics and must be overcome to realize the promise of nanomedicine in patients. More specifically, we need to determine the design criteria - the size, charge and configuration of various nanoparticle platforms - that optimize drug delivery to tumors.

The goal of the Cancer Nanomedicine project is the development of a mathematical framework for the delivery of therapeutic nanoparticles to solid tumors. The model accounts directly for the properties of the tumor microenvironment as well as for the properties (size and charge) of nanoparticles to predict their intratumoral distribution. We use experimental data to inform our mathematical models in order to construct "design maps" that predict the nanoparticle properties that optimize intratumoral delivery, and thus the efficacy of cancer therapy. Our models can also provide guidelines for the optimal use of vascular normalization and solid stress alleviation treatments to modify the tumor microenvironment and improve the distribution of nanomedicine to solid tumors.
