Pegylated interleukin-10
First Claim
1. A method of treating an inflammatory disease in a human subject comprising administering to said human subject a therapeutically effective amount of pharmaceutical composition comprising a monopegylated PEG-IL10 (mono-PEG-IL-10), the mono-PEG-IL-10 comprising one or more polyethylene glycol (PEG) molecules covalently attached via a linker to the alpha amino group of the N-terminal amino acid residue of a single subunit of IL-10, and a pharmaceutically acceptable carrier.

Abstract
Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.
