When will the ARMR Sciences fentanyl vaccine start human trials?

The first human clinical trial for the ARMR Sciences fentanyl vaccine is scheduled to begin in early 2026.

How does the new fentanyl vaccine work?

The vaccine creates antibodies that capture fentanyl in the bloodstream, preventing it from entering the brain and causing overdoses.

What is the difference between the fentanyl vaccine and naloxone (Narcan)?

The vaccine aims to prevent fentanyl from having any effect, while naloxone reverses the effects after an overdose has occurred.

Breakthrough Fentanyl Vaccine Heads to Human Testing

A promising new vaccine that could protect against the deadly effects of fentanyl is advancing to human clinical trials. Developed by ARMR Sciences, the vaccine demonstrated success in animal studies and is designed to prevent fentanyl from reaching the brain by creating antibodies that neutralize the drug in the bloodstream.

The first human safety trial is scheduled to commence in early 2026 at the Center for Human Drug Research in the Netherlands. This trial will assess the vaccine's safety and immune response in approximately 40 participants. Subsequent trials will evaluate its efficacy in humans, aiming to provide the first preventive measure against fentanyl overdoses.

This development, funded in part by the U.S. Department of Defense, offers hope for individuals struggling with opioid use disorder, first responders, and national security personnel. Experts believe this could pave the way for similar vaccines against other dangerous drugs like cocaine and methamphetamine.
