Abstract: Embodiments of the innovation relate to a dermal patch, comprising a substrate; a set of projections coupled to the substrate and configured to be at least partially insertable into skin, at least a portion of each projection of the set of projections comprising a biodegradable material; and a ghrelin blocker material encapsulated in the plurality of projections. The set of projections are coupled to the substrate via an adhesive that is configured to be dissolved within the skin after the patch is applied to the skin for a predetermined time, thus resulting in separation of the set of projections from the substrate. Once embedded in the skin, the protrusions can degrade and release the anti-ghrelin antibody encapsulated therein. The released anti-ghrelin antibody can find its way into the subject's circulatory system.
