Patent number: 11305010Abstract: Fentanyl is an addictive prescription opioid that is over 80 times mora potent than morphine. The synthetic nature of fentanyl has enabled the creation of dangerous “designer drug’ analogues that escape toxicology screening, yet display comparable potency to the parent drug. Alarmingly, a large number of fatalities have been linked to overdose of fentanyl derivatives. Herein, we report an effective immunotherapy for reducing the psychoactive effects of fentanyl class drugs. A single conjugate vaccine was created that elicited high levels of antibodies with cross-reactivity for a wide panel of fentanyl analogues, Moreover, vaccinated mice gained significant protection from lethal fentanyl doses. Lastly, a surface plasmon resonance (SPR)-based technique was established enabling drug specificity profiling of antibodies derived directly from serum. Our newly developed fentanyl vaccine and analytical methods may assist in the battle against synthetic opioid abuse.Type: GrantFiled: January 18, 2017Date of Patent: April 19, 2022Assignee: The Scripps Research InstituteInventor: Kim D.
