13‐Deoxy, 5‐iminodoxorubicin (GPX‐150) is a doxorubicin (DOX) analog synthesized to reduce the formation of reactive oxygen species and the cardiotoxic metabolite, doxorubiciniol, the two pathways that are linked to the irreversible, cumulative dose‐dependent cardiotoxicity of DOX. In a preclinical chronic models and a phase I clinical study of GPX‐150, no irreversible, cumulative dose‐dependent cardiotoxicity was demonstrated. Recent studies suggest that DOX cardiotoxicity may be mediated, at least in part, by the poisoning of topoisomerase IIβ.
