Abstract: A physically stable composition in the form of an injectable aqueous solution, wherein the pH is from 6.0 to 8.0, including at least: a) a basal insulin which isoelectric point (pI) is from 5.8 and 8.5 and b) a copolyamino acid according to formula I: Q[Hy]j[PLG]k?? Formula I wherein: j?1; k?2.

Abstract: A composition, in aqueous solution, comprising insulin in hexameric form, at least one substituted anionic compound and at least one polyanionic compound, said substituted anionic compound consisting of a discrete number n of between 1 and 8 of identical or different saccharide units, linked via identical or different glycoside bonds, said saccharide unit or one of said saccharide units being in open, oxidized or reduced form, said compound comprising salifiable carboxyl groups and said substituted anionic compound bearing on its reductive chain end at least one radical AA resulting from an aromatic amino acid comprising a phenyl or an indole, which may or may not be substituted, or an aromatic amino acid derivative comprising a phenyl or an indole, which may or may not be substituted.

Abstract: An anionic polysaccharide comprising carboxylic acid functional groups of formula I: in which: the polysaccharide may be either, synthetic or modified, i represents the degree of functionalization of the hydroxyls, j represents the degree of functionalization of the hydroxyls, L and Q represent an optionally branched and/or unsaturated chain comprising from 1 to 15 carbons, F is a functional group chosen from the group consisting of the carbamate functional group, the carbonyl being bonded to the Q radical, the ester functional group, the carbonyl being bonded to the Q radical, the amide functional group, the carbonyl being bonded to the Q radical, and the carboxylate functional group, and Grp is chosen from the group consisting of a mono- or divalent cation and of a chain comprising from 4 to 50 carbons.
