The present invention provides hyaluronic acid derivatives including one or more of each of repeating units represented by the formulae (Ia), (Ib), and (Ic) in which certain cationic sites, certain hydrophobic sites, and certain hydrophilic sites have been introduced. In addition, the present invention provides complexes of the hyaluronic acid derivatives with a drug and pharmaceutical compositions including the hyaluronic acid derivatives, in particular, complexes of the hyaluronic acid derivatives with a drug.
Provided are: a hyaluronic acid derivative composition that comprises (A) a hyaluronic acid derivative having a steryl group introduced therein; and (B) a polar group-containing compound having at least one functional group selected from the group consisting of hydroxy group, carboxy group, amino group, amide group, carbamate group, urea group and thiol group, wherein the steryl group has been introduced at a ratio of 0.1% or more and less than 35% relative to the hyaluronic acid derivative (A); a pharmaceutical composition that contains the hyaluronic acid derivative composition as a carrier; and a hyaluronic acid derivative-drug conjugate composition wherein, in the hyaluronic acid derivative composition, one or more drugs are conjugated to the hyaluronic acid derivative (A).
