| abstract |
The present invention relates to pharmaceutical compositions for the controlled release of lipocalin muteins and conjugates thereof with a moiety selected from the group consisting of a protein, protein domain, peptide, lipid, fatty acid, polysaccharide and/or an organic polymer that comprise said lipocalin mutein of conjugate thereof in combination with a biodegradable polymer. The invention further relates to a method for the controlled delivery of the lipocalin muteins or conjugates thereof, methods for the production of a controlled release formulation and the thus produced formulation. Finally, the invention is directed to the use of the formulations of the invention for the controlled delivery of the lipocalin mutein, for extending the in vivo half-life of the lipocalin mutein, for increasing the bioavailability of the lipocalin mutein, or for decreasing the immunogenicity of the lipocalin mutein upon administration to a subject as well as methods for the treatment of a disease or disorder comprising the administration of the formulations of the invention to a subject in need thereof. |
