Therapeutic polymeric nanoparticles and the methods of making and using thereof: a patent evaluation of WO2015036792 (original) (raw)

Expert Opinion on Therapeutic Patents, 2016

Abstract

ABSTRACT Evaluation of the patent application WO2015036792 claiming therapeutic polymeric nanoparticles loaded with AZD1152-hqpa (aurora kinase inhibitor), and methods of making and using same for the treatment of cancer, is described. The claimed polymeric nano-formulations containing hydrophobic acid significantly improved the pharmacokinetic profiles (slow/sustained drug release profile) of the drug AZD1152-hqpa, as compared to the control agent (AZD1152). Drug efficacy and tolerability were also improved, and toxicity decreased in in vivo animal experiments, resulting in a better therapeutic index for the nano-formulation. Hence, the nano-formulated AZD1152-hqpa could be tested in the clinic at a dose level similar to, or higher than, that used for AZD1152, with lower incidence of toxicity.
