Abstract: The invention relates in general to pharmaceutical compositions, means and methods for sustained release of therapeutic agents for local treatments. It relates in particular to means and methods for local treatment of cancer diseases by embedding lyophilized Mitomycin C in a slowly releasing biocompatible hydrogel applied to affected tissue.

Abstract: Provided herein are compositions including a thermoreversible hydrogel, and having an extended, medically suitable in-use period. A medically suitable in-use period following reconstitution can be up to about 96 hours, up to about 72 hours, up to about 48 hours, up to about 24 hours, or up to about 12 hours at room temperature. Also provided, are methods including administering the compositions up to about 96 hours, up to about 72 hours, up to about 48 hours, up to about 24 hours, or up to about 12 hours at room temperature following reconstitution.

Abstract: A hydrophilic biocompatible sustained-release material is disclosed. The material comprises amounts of an ethylene oxide/propylene oxide block copolymer, HPMC, and water, effective to produce a composition of sufficiently low viscosity at room temperature to be injectable into an internal body cavity via a tube inserted within a urinary catheter. At body temperature, the material exhibits a much higher viscosity and will stably adhere to the internal surface of a body cavity. As the material dissolves, a therapeutic agent incorporated therein is slowly released to the body cavity, while the material itself is excreted from the body.

Abstract: A method of providing sustained-release topical treatment of a condition affecting an internal body cavity is provided. The method comprises administering a pharmaceutical composition comprising a thermoreversible hydrogel and an active pharmaceutical ingredient to an internal body cavity of the urinary tract. After administration, the concentration of the active pharmaceutical ingredient in urothelium of the internal body cavity is increased when compared to the concentration of the active pharmaceutical ingredient in urothelium of the internal body cavity following administration of a control composition comprising the same dose and concentration of active pharmaceutical ingredient in water.

Abstract: Described herein are compositions and methods for treating cancer of a body cavity, specifically urinary tract cancer, by way of a combination of at least two immunomodulatory agents, wherein one or more of the therapeutic agents are embedded in, and slowly released from, a biocompatible hydrogel composition.

Abstract: A method is disclosed for production of a sterile thermoreversible hydrogel characterized by a known temperature Tmin at which the viscosity reaches at least a local minimum. In a preferred embodiment of the invention, the method comprises dissolving the components in water within ±4° C. of Tmin; forming the thermoreversible hydrogel; and filtering the thermoreversible hydrogel at Tmin. The final sterilization can be obtained by filtering under aseptic conditions or by autoclaving or irradiation of the final product. In other embodiments, the components of the gel are dissolved in a sufficiently large quantity of water that reduces the gel viscosity or precludes formation of a thermoreversible hydrogel, and sufficient water is then removed under vacuum to produce the final thermoreversible hydrogel.
