Effect of ketoconazole-mediated CYP3A4 inhibition on clinical pharmacokinetics of panobinostat (LBH589), an orally active histone deacetylase inhibitor

Abstract

Co-administration of panobinostat with CYP3A inhibitors is feasible as the observed increase in panobinostat PK parameters was not considered clinically relevant. Considering the variability in exposure following enzyme inhibition and the fact that chronic dosing of panobinostat was not studied with CYP3A inhibitors, close monitoring of panobinostat-related adverse events is necessary.
