  • Publication number: 20130177607
    Abstract: Nanocells allow the sequential delivery of two different therapeutic agents with different modes of action or different pharmacokinetics. A nanocell is formed by encapsulating a nanocore with a first agent inside a lipid vesicle containing a second agent. The agent in the outer lipid compartment is released first and may exert its effect before the agent in the nanocore is released. The nanocell delivery system may be formulated in pharmaceutical composition for delivery to patients suffering from diseases such as cancer, inflammatory diseases such as asthma, autoimmune diseases such as rheumatoid arthritis, infectious diseases, and neurological diseases such as epilepsy. In treating cancer, a traditional antineoplastic agent is contained in the outer lipid vesicle of the nanocell, and an antiangiogenic agent is loaded into the nanocore. This arrangement allows the antineoplastic agent to be released first and delivered to the tumor before the tumor's blood supply is cut off by the antianiogenic agent.

  • Patent number: 8404222
    Abstract: PEG and related polymer derivatives having weak, hydrolytically unstable linkages near the reactive end of the polymer are provided for conjugation to drugs, including proteins, enzymes, small molecules, and others. These derivatives provide a sufficient circulation period for a drug-PEG conjugate, followed by hydrolytic breakdown of the conjugate and release of the bound molecule. In some cases, drugs that demonstrate reduced activity when permanently coupled to PEG maintain a therapeutically suitable activity when coupled to a degradable PEG in accordance with the invention. The PEG derivatives of the invention can be used to impart improved water solubility, increased size, a slower rate of kidney clearance, and reduced immunogenicity to a conjugate formed by attachment thereto. Controlled hydrolytic release of the bound molecule into an aqueous environment can then enhance the drug's delivery profile by providing a delivery system which employs such polymers and utilizes the teachings provided herein.

  • Patent number: 8361484
    Abstract: One aspect of the invention relates to a hydrogel comprising a polymer comprising a plurality of pendent hydroxyl groups, a crosslinker, and a sclerosing agent. Another aspect of the invention relates to a method for reducing lung volume in a patient comprising the steps of advancing into a region of a patient's lung via said patient's trachea a multi-lumen catheter lumen through a bronchoscope; and co-administering, through the multi-lumen catheter, a first mixture comprising a first amount of a polymer containing a plurality of pendent hydroxyl groups; a second mixture comprising a second amount of a crosslinker; and a third mixture comprising a third amount of a sclerosing agent; thereby forming a hydrogel in said region. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema of the lung.

  • Publication number: 20130022545
    Abstract: A drug delivery system for the treatment of liver cancer that is based on interventional injection of a temperature and pH-sensitive hydrogel is provided. The drug delivery system is composed of a block copolymer applicable to hepatic arterial catheterization and a therapeutic agent is loaded inside the drug delivery system, and the drug delivery system is in the sol state outside, and undergoes a phase transition into the gel state inside the hepatic artery, thereby delaying or blocking blood supply of the hepatic artery, and slowly releasing the therapeutic agent during the phase transition into the gel state inside the hepatic artery.
