  • Patent number: 6565888
    Abstract: The present invention relates to a sustained release composition for the targeted delivery of biologically active agents to specific tissues and cells. The composition comprises microparticles containing a biocompatible polymer, a water-soluble polymer and a biologically active agent. In one embodiment, the biologically active agent is an antigen or an immunomodulator. In another embodiment, the biologically is a labile agent. The microparticles have a number median diameter of greater than 20 microns upon administration. The water-soluble polymer is present in the sustained released composition in at least about 20% of the dry weight of the microparticle. The sustained release composition provides for the dissolution of the water-soluble polymer of the composition upon hydration, at a much greater rate than the degradation of the biocompatible polymer.
