    Abstract: The present application provides a composition comprising (1) a lipid composition comprising an ionizable amino lipid and a quaternary amine compound and (2) a polynucleotide. The present application also provides a composition comprising (1) a lipid composition comprising an asymmetric phospholipid, an ionizable amino lipid, and optionally a quaternary amine compound and (2) a polynucleotide, wherein the composition is formulated for intratumoral delivery of the polynucleotide. The present application further provides pharmaceutical compositions for intratumoral delivery comprising (1) a lipid composition comprising a compound of formula (I) and (2) therapeutic agent or a polynucleotide encoding the therapeutic agent, e.g., an mRNA encoding a therapeutic protein or a fragment thereof. Further provided is a method of increasing retention of a polynucleotide in a tumor tissue by using such a composition.
