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.

Micromolded or 3-D printed pulsatile release vaccine formulations

Microneedle patches and systems, and methods for use of such patches and systems. In one aspect, a microneedle patch is provided including a tab portion for handling the microneedle patch. In another aspect, a system is provided including a microneedle patch and a tray for housing the microneedle patch. In still another aspect, various indicators providing for providing feedback prior to, during, and after administration of the microneedle patch are provided. Advantageously, the described microneedle patches and systems provide improved handling and ease of application of the microneedle patches to skin for the delivery of therapeutic agents.

Microneedle patches and methods

In one embodiment, the present application discloses compounds that are selective neuroactive agents for the treatment of diseases of the central nervous system (CNS). In one aspect, the neuroactive agents are NCDs of metal chelates, including complexes of iron, copper or zinc.
