  • Patent number: 6800672
    Abstract: Biodegradable, flowable or flexible polymer compositions are described comprising a polymer having the recurring monomeric units shown in formula I: wherein: each of R and R′ is independently straight or branched alkylene, either unsubstituted or substituted with one or more non-interfering substituents; L is a divalent cycloaliphatic group; R″ is selected from the group consisting of H, alkyl, alkoxy, aryl, aryloxy, heterocyclic or heterocycloxy; and n is 5 to 1,000, wherein said biodegradable polymer is biocompatible before and upon biodegradation. In one embodiment, one or more of R, R′ or R″ is a biologically active substance. Amorphous compositions containing a biologically active substance, in addition to the polymer, and methods for controllably releasing biologically active substances using the compositions, are also described.

  • Publication number: 20040071774
    Abstract: Biodegradable polymer compositions suitable for intraperitoneal administration to treat a mammalian subject having ovarian cancer are described, wherein the polymer compositions provide extended release of the antineoplastic agent into the peritoneum of the subject. The subject compositions can increase the median survival rate from the cancer by at least about 10%, as compared with the median survival rate obtained by administration of a composition comprising the same dosage of the antineoplastic agent without the biodegradable polymer. Solid articles and methods for treating ovarian cancer are also described.
