Method for administering interleukin-2
First Claim
1. A method for administering interleukin-2, comprising the step of intracranially implanting into an area from which a neoplasm has been removed a controlled-release polymer matrix, comprising a biocompatible, bioerodible, hemostatic polylactic acid polymer material and interleukin-2 which material is malleable at the time of implantation.

Abstract
A biocompatible, biodegradable, bioerodible composite polymer matrix comprising interleukin-2 in an appropriate polymer. The polymer may be a polymer or copolymer of lactic acid, lactide, glycolide, glutamic acid, or it may be collagen or albumin. The material contains from 102 to 108 U IL-2/g of polymer. Also disclosed is a method for making the composite polyer matrix and a method for implanting the material. A soft, malleable controlled-release composite material may be used for intracranial or other implantation and may be shaped or molded to fit the site from which malignant tissue has been removed, opposing the residual tumor, complementing hemostasis, compatible with anatomical structure, and functioning as an implantable immunotherapeutic adjuvant.
