Current chemotherapeutics are plagued by poor solubility and selectivity, requiring toxic excipients in formulations and causing a number of dose limiting side effects. Nanoparticle delivery has emerged as a strategy to more effectively deliver chemotherapeutics to the tumour site. Specifically, polymeric micelles enable the solubilization of hydrophobic small molecule drugs within the core and mitigate the necessity of excipients. Notwithstanding the significant progress made in polymeric micelle delivery, translation is limited by poor stability and low drug loading. In this work, a rational design approach is used to chemically modify poly(D,L-lactide-co-2-methyl-2-carboxytrimethylene carbonate)-graft-poly(ethylene glycol) (P(LA-co-TMCC)-g-PEG) in order to overcome these limitations and effectively deliver drug to tumours. The PEG density of the polymer system was optimized to enhance the stability of our polymeric micelles. Higher PEG densities permitted the lyophilization of micelles and enhanced the serum stability of the system. To increase the drug loading of our system, we facilitated specific intermolecular interactions within the micelle core. For drugs that form colloidal aggregates, such as pentyl-PABC doxazolidine, polymers were used to stabilize the colloidal core against aggregation and protein adsorption. For more challenging molecules, where self-assembly cannot be controlled, such as docetaxel, we modified the polymeric backbone with a peptide from the binding site of the drug to achieve loadings five times higher than those achieved in conventional micelle systems. This novel docetaxel nanoparticle was assessed in vivo in an orthotopic mouse model of breast cancer, where it showed a wider therapeutic index than the conventional ethanolic polysorbate 80 formulation. The improved tolerability of this formulation enabled higher dosing regimens and led to heightened efficacy and survival in this mouse model. Combined, these studies validated P(LA-co-TMCC)-g-PEG nanoparticles as an effective delivery vehicle for two chemotherapeutics, and presents approaches amenable to the delivery of many other clinically relevant hydrophobic drugs or drug combinations.

This book focuses on current advancements in the field of block copolymers and covers design, concept, and various therapeutic applications in the drug delivery. It also reviews the use of block copolymers in drug delivery applications from the development of sustained release products to smart polymeric delivery systems such as stimuli-responsive polymeric systems, for example, thermosensitive, redox-sensitive, photo-sensitive, and enzyme-sensitive. The book further discusses the nano assemblies from amphiphilic block copolymers as nanomedicine platforms for diagnosis and therapy due to their relatively small size, high drug loading capacity, controlled drug release, in vivo stability, and prolonged blood circulation. The chapters also review the various patents and ongoing clinical trials on the applications, covering several important new concepts and findings in the field of block copolymers. The book is aimed at researchers, academicians, and industrial scientists involved in the development of drug-delivery systems based on polymers.
