Abstract: Compositions for stabilizing and delivering proteins and/or other bioactive agents are disclosed. The bioactive agents are embedded or encapsulated in a crystalline matrix. Typically the bioactive agents are in the form of micro- or nanoparticles. The crystalline matrix confers enhanced stability to the agents embedded therein relative to other microparticulate or nanoparticulate bioactive agents. The carriers are especially useful for stabilizing bioactive macromolecules, such as proteins.

Abstract: Compositions including Glucagon-like peptide-1 (GLP-1) or an analogue thereof such as exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide, semaglutide, or taspoglutide, entrapped in or incorporated into a polymeric particles are provided. Typically, the particles are composed of one or more biodegradable polyesters or polyanhydrides, or a combination thereof, for example as copolymers or a blend to two or more polymers or copolymers. In some embodiments, the particles do not include a poly(lactide-co-glycolide). The particles can be microparticles or nanoparticles. In some embodiments, the particles are formed by Phase Inversion Nanoencapsulation (PIN). Pharmaceutical compositions and dosage forms, including formulations suitable for oral delivery, are also provided. Method of treating subject in need thereof, for example subjects with diabetes, by administering the subject an effect amount of the disclosed compositions, are also provided.

Abstract: Compositions and methods for the treatment of cancer and/or inflammatory diseases are provided. A combination of interleukin-10 (IL-10) and interleukin-12 (IL-12) is used to treat cancer and/or inflammatory diseases, and a combination of an anti-PD-1 antibody and an anti-IL-17 antibody is used to treat cancer.

Abstract: The present invention provides compositions and methods for preventing the development of or reducing the growth of gastrointestinal tumors. The composition comprises polymeric microspheres encapsulating sulindac, IL-12 or both. These polymeric microspheres can be administered orally to individuals to reduce the growth of or prevent the development of gastrointestinal tumors.

Abstract: A method is provided to increase the immunogenicity of an antigen. This method involves the covalent coupling of the antigen to proteins or glycoproteins present on the surface of dendritic cells by a mild biochemical modification which minimizes the denaturation of the antigen and preserving cell viability. Dendritic cells with covalently linked antigen on their surface can be used for generating a specific response to the antigen. The present method can be used for both therapeutic and preventive purposes.
