Abstract: Formulations and methods for their preparation including a hydrogel including a crosslinked matrix comprising a polymer, and a one or more liposomes containing a therapeutic agent.

Abstract: Formulations of cross-linkable polymers, capable of forming non-toxic and biocompatible hydrogels in situ, containing at least one of doxycycline or minocycline. Methods of using the hydrogels for treating the skin or ocular tissues of mammals exposed to vesicant compounds such as sulfur mustard (SM), nitrogen mustard (NM) or half mustard (2-chloroethyl ethyl sulfide (CEES)) are also disclosed.

Abstract: A multifunctional polyethylene glycol-based hydrogel that includes a multi-arm polyethylene glycol cross-linking unit covalently bound to at least four multi-arm polyethylene glycol nanocarrier units, wherein each nanocarrier unit includes an agent coupled to the nanocarrier unit and each agent is selected from pH-lowering agents, bioadhesion agents, microbicidal-spermicidal agents, and agents that inhibit free and cell-associated HIV binding, provided that each nanocarrier unit comprises a different agent.

Abstract: The American Cancer Society estimated that in 2009, 1,479,350 new cancer cases would be diagnosed in the United States of which 219,440 would be lung and bronchus related. The standard treatments for NSCLC include surgery, chemotherapy, radiation, laser and photodynamic therapy, all with various success rates depending on the stage of the cancer. National Cancer Institute assesses, however, that results of standard treatment are generally poor with only a 15 percent 5-year survival rate for combined cancer stages. Challenges facing the current chemotherapy drugs include excessive toxicity to healthy tissues and limited ability to prevent metastases. A dual drug delivery system described herein selectively targets the lung to deliver anti-cancer drugs and inhibit the formation of metastases.

Abstract: Peptide ligands for transporting therapeutic agents across the intestinal epithelial barrier that ordinarily are inadequately absorbed and must be delivered by alternative means, which contain an isolated amino acid sequence wherein at least one pair of amino acids are of an opposite charge and the pair members are separated by a spacer of 1-12 amino acid residues including at least one hydrophobic amino acid, and wherein the length of the amino acid sequence is greater than 5 and less than 20 amino acids. Pharmaceutical compositions for gastro-intestinal delivery and methods for the gastrointestinal delivery of poorly absorbed therapeutic agents are also disclosed.

Abstract: Novel classes of multi-arm polyalkylene oxide-based materials including PEG nanocarriers, nanogel particles, and aggregated nanogel particles are disclosed. These classes of compositions may be associated with therapeutic agents and targeting moieties, or visibility enhancing agents, and may have a modified surface structure. In some embodiments the PEG-based materials can be made to provide relatively high drug loads with improved solubility and targeted delivery.

Abstract: The instant invention relates to polyethylene glycol-based dendrons, otherwise known as PEGtide dendrons, compositions thereof and methods of use.

Abstract: This invention provides multimeric nanocarrier for in vivo delivery of a bioactive agent, comprising at least two peptide monomers reversibly or irreversibly linked with one or more of said bioactive agents, wherein said two or more of said peptide monomers are covalently linked by a biodegradable difunctional moiety, as well as methods of using this nanocarrier.

Abstract: Described is a spray-on hydrogel comprising water-soluble PEG polymers that cross-link in situ to form a hydrogel such that the cross-links are reversible. The hydrogel can be useful as a drug delivery composition, wound dressing or surgery adjuvant. Polyethylene glycol polymer and cross-linker solutions are sprayed simultaneously through a common orifice. Cross-linking via formation of thioether or disulfide bonds is initiated upon mixing, providing rapid gelation. The hydrogel components can be derivatized with RGD peptides or analogs thereof to promote retention in/on a body compartment such as the skin, surface of the eye, or a mucosa such as the vaginal mucosa. The cross-links are reversed using a reducing solution enabling easy removal of the hydrogel by dissolution. Processes for preparation of the cross-linker, RGD derivatized PEG and RGD-linked agents are also disclosed.

Abstract: This invention concerns an in situ biodegradable hydrogel drug delivery system in which the components are assembled in a manner that provides a mechanism for the timed cleavage of a particular amide bond in a covalently linked active agent or of the hydrogel structure.

Abstract: Non-Small Cell Lung Carcinomas (NSCLCs) are treated with Gel Micro-Particles (GMPs) that passively accumulate in the lungs and contain Nano-Particles (NPs) combining one or more therapeutic agents that are cytotoxic to the NSCLC with one or more NSCLC active targeting ligands, as well as one or more other optional agents that increase cellular uptake, enhance the pro-apoptotic effect of the chemotherapeutic agent(s), and the like. NPs targeting other cancer cells are also disclosed, as well as NP-containing GMPs that reduce the occurrence of tumor metastasis.
