Vaccine Design

Click through the slides to learn about the core components of our vaccine.


Molecular antigen that structurally resembles the target drug,

providing a template for the formation of anti-drug antibodies.

We introduce a chemically contiguous hapten that carries dual epitopes to encompass the six target opioids.

Our Epitope #1 Design

Epitope #1

(Morphine, codeine, oxycodone, hydrocodone, heroin):

Morphinan ring scaffold

that is conserved across

the molecular structures

of the opioids

Epitope #2


Modified form of fentanyl that

allows it to closely resemble a

fentanyl molecule without

behaving like it

Put together, our vaccine design looks like this:
