Abstract:
Emulsion-based and micromolded (“MM”) or three dimensional printed (“3DP”) polymeric formulations for single injection of antigen, preferably releasing at two or more time periods, have been developed. Formulations are preferably formed of biocompatible, biodegradable polymers. Discrete regions encapsulating antigen, alone or in combination with other antigens, adjuvants, stabilizers, and release modifiers, are present in the formulations. Antigen is preferably present in excipient at the time of administration, or on the surface of the formulation, for immediate release, and incorporated within the formulation for release at ten to 45 days after initial release of antigen, optionally at ten to 90 day intervals for release of antigen in one or more additional time periods. Antigen may be stabilized through the use of stabilizing agents such as trehalose glass. In a preferred embodiment for immunization against polio, antigen is released at the time of administration, and two, four and six months thereafter.
Abstract:
Enteric elastomers and related methods are generally provided. In some embodiments, the enteric elastomer is a polymer composite. Certain embodiments comprise a polymer composite in which hydrogen bonds within two carboxyl group-containing polymers cross-link the polymer networks into an elastic and pH-responsive polymer composite. Advantageously, this polymer composite has the capacity of being stable and elastic in an acidic environment such as that of the stomach but can be dissolved in a neutral pH environment such as that of the small and large intestines. In some embodiments, the polymer composites described herein comprise a mixture of two or more polymers with carboxyl functionality such that the two or more polymers form hydrogen bonds. In certain embodiments, the polymer composite has both enteric and elastic properties.
