Hapten
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
​
(Fentanyl):
​
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:
