APS Granted Two Bioerodible Polymer Patents; Composition of Matter Patents Related To Its Bioerodible Polymer Technology.REDWOOD CITY Redwood City, city (1990 pop. 66,072), seat of San Mateo co., W Calif., on San Francisco Bay; inc. 1868. Manufactures include commmunications, electrical, electronic, and medical equipment. , Calif.--(BUSINESS WIRE)--Oct. 25, 1999-- Advanced Polymer Systems, Inc. (Nasdaq: APOS APOS American Psychosocial Oncology Society APOS After Point of Sales APOS Acoustic Processor Operating Station APOS Advanced Process Oriented Steering ) today announced that it has been issued US Patent 5,968,543, "Polymers with Controlled Physical State and Bioerodibility", and US Patent 5,939,453, "Poly(Ortho Ester-Poly(Ethylene Glycol ethylene glycol: see glycol. ethylene glycol Simplest member of the glycol family, also called 1,2-ethanediol (HOCH2CH2OH). It is a colourless, oily liquid with a mild odour and sweet taste. ) Block Copolymers". The new patents are based on inventions by Advanced Polymer Systems related to its bioerodible drug delivery systems. The issued claims for patent 5,968,543 cover the composition and important uses of a new family of bioerodible polymers known as poly(ortho esters esters (esˑ·terz), n.pl organic compounds synthesized from acids and alcohols, typically possessing fruity aromas. ). These polymers are designed for placement at a suitable body site where they undergo a controlled bioerosion process. They can be used as biomatrices (e.g. in orthopedic and tissue engineering applications), and can also release physically incorporated therapeutic agents in a precisely controlled manner. Current uses under investigation at Advanced Polymer Systems involve a number of areas, including, post-operative treatment of cancer, post-operative pain control, protein release and various veterinary applications. The issued claims for patent 5,939,453 cover the composition and important uses of another family of bioerodible polymers, known as block copolymers, that use blocks of poly(ortho esters) and blocks of poly(ethylene glycol) arranged in various combinations. These polymers are designed as delivery systems for drugs, e.g. to deliver anticancer agents selectively to tumors, thus greatly decreasing systemic toxicity of conventionally administered anticancer agents.
