We have developed a new strategy to temporarily blunt the reticuloendothelial
system uptake of nanodrugs, a major challenge for nanodrug delivery and causing
off-target toxicities, using an FDA approved nutrition supplement, Intralipid. We
have tested our methodology in rats using an experimental platinum-containing
anti-cancer nanodrug and three FDA approved nanodrugs, Abraxane, Marqibo, and
Onivyde, to determine their toxicities in liver, spleen, and kidney, with and
without the addition of Intralipid. Our method illustrates its potentials to
deliver nanodrugs with an increase in the bioavailability and a decrease in
toxicities. Our study shows that Intralipid treatment exhibits no harmful effect
on tumor growing and no negative effect on the anti-tumor efficacy of the
platinum-containing nanodrug, as well as animal survival rate in a HT-29
xenograft mouse model. Our methodology could also be a valuable
complement/supplement to the "stealth" strategies. Our approach is a general one
applicable to any approved and in-development nanodrugs without additional
modification of the nanodrugs, thus facilitating its translation to clinical
settings.
