  The present invention relates to a fiber comprising a biodegradable polymer which undergoes dimensional change upon injection in the human or animal body wherein the dimensional change is a reduction of the surface area to volume ratio of a factor 2 to 10. The fiber is sized for injection via a pharmaceutical syringe needle having a bore of at least 25 Gauge. The biodegradable polymer is an amorphous biodegradable polymer selected from the group of poly-hexamethylene carbonates or polyesteramides. The amorphous biodegradable polymer is a preferably a polyesteramide comprising alpha-amino acids, diols and dicarboxylic acids as building blocks. The invention further relates to the use of the fiber for the manufacturing of a medicament for the treatment of ophthalmic diseases. The invention also relates to a process for the manufacturing of the fiber comprising the following process steps; a. extruding a biodegradable polymer into a fiber fitting in a needle of at least 25 Gauge b. which while under tension is cooled below its glass transition temperature such that the resultant fiber is amorphous.

  The present invention relates to a drug delivery composition comprising proteins and biodegradable polymers. The present invention further relates to a drug delivery system for controlled and long term release of proteins into a biological environment. The drug delivery composition comprises at least a protein and a biodegradable polymer possessing at least two different functional groups selected from the group of chosen among carboxyl-, ester-, amine-, amide-, thiol-, thioester- or hydroxyl groups pendant to the main polymer chain whereby the composition absorbs between 5-10% w/w water when exposed to physiological conditions for at least 20 days. The present invention further relates to a drug delivery system for controlled protein release comprising the composition. The drug delivery system may be chosen from microparticles, films, coatings, fibers, pellets, cylinders, discs, implants, microcapsules, microspheres, nanospheres, wafers, micelles, liposomes or woven or non-woven fabrics.
