TheraJect, Inc. is a preclinical stage biopharmaceutical 
company committed to the drug delivery including vaccines 
via a novel, needle-free transdermal technology.
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.
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.
