Human Biomolecular Corona of Liposomal Doxorubicin: The Overlooked Factor in Anticancer Drug Delivery.

More than 20 years after its approval by the Food and Drug Administration (FDA), liposomal doxorubicin (DOX) is still the drug of choice for the treatment of breast cancer and other conditions such as ovarian cancer and multiple myeloma. Yet, despite the efforts, liposomal DOX did not satisfy expectations at the clinical level. When liposomal drugs enter a physiological environment, their surface gets coated by a dynamic biomolecular corona (BC).
