    摘要: The invention provides a controlled release biodegradable polymer formulation adapted for administering bioactive agents such as therapeutic proteins to a patient through implantation of a bolus that forms a depot within the patient's body tissues. The formulation includes a dehydrated inclusion complex of the bioactive agent within a hydrogel, wherein the hydrogel can comprise a polymerized polyalkyleneglycolyl diacrylate, and, optionally, polyalkyleneglycolyl monoacrylates, including methacrylates. Alternatively, the hydrogel can comprise hyaluronic acid, chitosan, agarose, polyvinylacetate, polyvinylpyrrolide, or polyvinylalcohol nanoparticles. The bioactive agent can be a macromolecular material, such as a protein. A method of forming the inventive formulation is also provided, as well as a method for using the formulation in the treatment of a malcondition in a patient in need thereof.
