TheraJect, Inc. is a preclinical stage biopharmaceutical
company committed to the delivery of vaccines via a novel,
needle-free transdermal technology into a dermal
environment rich in antigen presenting cells to generate an
enhanced immune response.

TheraJect is focused on enhancing the efficacy of existing
vaccines, enabling new vaccines and expanding the global
vaccine market.
The TheraJect patch consists of an array of dissolvable
microneedles that create superficial pathways through the
skin's dead barrier layer, allowing transport of
macromolecules into the viable epidermis. The array is held
in place by a traditional adhesive patch. The microneedles
dissolve within minutes in the interstitial fluid, delivering the
drug or vaccine. The microneedle components are selected
from a broad range of dissolving materials, all of which are
either GRAS or have been used in injectibles before. The
drug or vaccine to be delivered is mixed with the
microneedle materials to form a hydrogel, poured into a
mould, dried and then cut and assembled with an adhesive
patch. This extremely simple, “fill and finish” like process is
eminently scalable.
