From the clinical editor

The efficacy of doxorubicin (DOX) may be maximized and dose-limiting cardiotoxicity minimized by controlled release from PEGylated nanoparticles. Administration of 18 mg/kg of free DOX induced a sevenfold increase in CPK levels and significant decreases in left ventricular fractional shortening in mice, whereas nanoparticle-encapsulated DOX produced none of these pathological changes.
