Fast-acting delivery to prevent and reverse fentanyl and other opioid overdoses
A novel drug delivery system for the prevention and rescue of fentanyl and other opioid overdoses

What this research studies
Researchers are developing a delivery method designed to get an antidote into the brain quickly to counter fentanyl and related synthetic opioids. They will optimize how the system crosses the blood-brain barrier and binds to these drugs using lab and preclinical models and tests in blood and brain tissue. Safety and dosing studies will be done before any work moves toward human testing. If the project moves forward, future clinical work could include people at high risk of overdose or emergency responder settings.
Who could benefit from this research
Good fit: Ideal candidates for future trials would include adults at high risk of fentanyl exposure or with opioid use disorder, people with prior overdoses, and first responders or bystanders who might use the rescue option.
Not a fit: People who are not exposed to opioids or not at risk of fentanyl exposure, and those with allergies to the study drugs or other exclusionary medical conditions (e.g., some pregnancies), may not benefit or be eligible.
Why it matters
Potential benefit: If successful, this could provide faster and more effective reversal of fentanyl-related overdoses, potentially reducing deaths and long-term brain injury.
How similar studies have performed: Existing antidotes like naloxone work for many overdoses but can be less effective for potent fentanyl analogs, so rapid brain-targeted delivery is a novel approach that is still largely untested in humans.
