NCIt definition : A single protein encapsulation (SPE)-based drug formulation composed of nine molecules
of the anthracycline antibiotic doxorubicin encapsulated within a single unmodified
monomeric human serum albumin (HAS) molecule, with potential antineoplastic activity.
Upon administration, SPE doxorubicin SPEDOX-6 is specifically taken up by fast proliferating
tumor cells as HSA serves as a nutrient for tumor cells. Inside the tumor cell and
upon release from HSA, doxorubicin intercalates into DNA and inhibits the topoisomerase
II activity, which results in the inhibition of tumor cell DNA replication and tumor
cell proliferation. Encapsulation of doxorubicin within HSA improves the pharmacokinetic
(PK) profile of doxorubicin compared to unformulated doxorubicin with improved drug
penetration specifically into tumors over healthy cells due to both the high permeability
and retention effects of the tumor vasculature. This improves efficacy and lowers
the toxicity profile, including doxorubicin-induced cardiotoxicity.;
