  • Patent number: 7052719
    Abstract: A lipid or other hydrophobic or amphiphilic compound (collectively referred to herein as “hydrophobic compounds”) is integrated into a polymeric matrix for drug delivery to alter drug release kinetics. In embodiments where the drug is water soluble, the drug is released over longer periods of time as compared to release from the polymeric matrix not incorporating the hydrophobic compound into the polymeric material. In contrast to methods in which a surfactant or lipid is added as an excipient, the hydrophobic compound is actually integrated into the polymeric matrix, thereby modifying the diffusion of water into the microparticle and diffusion of solubilized drug out of the matrix. The integrated hydrophobic compound also prolongs degradation of hydrolytically unstable polymers forming the matrix, further delaying release of encapsulated drug.

  • Patent number: 7052686
    Abstract: Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.

  • Patent number: 7029688
    Abstract: The invention discloses materials that adsorb readily to the surfaces of body tissues in situ and provide a steric barrier between such tissues, so that tissue adhesions, which typically form following surgical procedures, are minimized. These materials contain a polymer of hydrophilic molecules such as polyethylene glycol (PEG) bound to a polymer that spontaneously adsorbs to biological tissue such as phenylboronic acid (PBA). The PEG-PBA co-polymer can be formed in a variety of geometries. The materials can also be used to coat prosthetics and other implants.

  • Patent number: 7025990
    Abstract: Methods are provided for forming hydrogel barriers in situ that adhere to tissue and prevent the formation of post-surgical adhesions or deliver drugs or other therapeutic agents to a body cavity. The hydrogels are crosslinked, resorb or degrade over a period of time, and may be formed by free radical polymerization initiated by a redox system or thermal initiation, or electrophilic-neutrophilic mechanism, wherein two components of an initiating system are simultaneously or sequentially poured into a body cavity to obtain widespread dispersal and coating of all or most visceral organs within that cavity prior to gelation and polymerization of the regional barrier. The hydrogel materials are selected to have a low stress at break in tension or torsion, and so as to have a close to equilibrium hydration level when formed.

  • Patent number: 7005124
    Abstract: Antineoplastic dendritic polymer conjugates which are useful drug delivery systems for carrying antineoplastic agents to malignant tumors are prepared by obtaining a dendritic polymer having functional groups which are accessible to an antineoplastic agent capable of interacting with the functional groups, and contacting the dendritic polymer with the antineoplastic agent. The preferred platin-based analogues of the antineoplastic agents conjugated to the dendritic polymer may be administered intravenously, orally, parentally, subcutaneously, intramuscularly, intraarterially or topically to an animal having a malignant tumor in an amount which is effective to inhibit growth of the malignant tumor. The antineoplastic dendritic polymer conjugates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, reduced toxicity, and improved anti-tumor activity in vivo.

  • Patent number: 6946118
    Abstract: Mucositis is treated and/or prevented by administrating to a patient a formulation comprising a tetracycline that is poorly absorbed from the gastro-intestinal tract. The tetracycline may be in the form of a pharmaceutically acceptable salt or a base. The formulations may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline. Such compositions have the advantage of treating the entire gastro-intestinal tract since the active ingredient is not removed from the tract via absorption. Further, such compositions minimize systemic exposure and accompanying side effects.
