Abstract
Compositions, methods, and systems are disclosed for the development and use of heparosan, a natural polymer related to heparin, as a new therapeutic modifying agent or complexation vehicle which can modulate drug cargo pharmacokinetics and behavior within a mammalian patient. In certain non-limiting embodiments, the use of heparosan is complexed with anti-cancer drugs and the like, thus forming a prodrug for the purposes of increasing efficacy and reducing side effects compared to the parental drug alone.
