NCT ID NCT05377255

First seen Apr 24, 2026 · Last updated May 12, 2026 · Updated 1 time

Summary

This study tested a new device (AP003) that delivers naloxone as a nasal spray to reverse opioid overdoses. Twenty-four healthy adults received multiple doses to see how the drug moves through the body and to check for side effects. The goal was to compare the new spray with the standard Narcan spray. This early-phase trial focused on safety and drug levels, not on treating an overdose directly.
