NCT ID NCT07079826
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a wearable device called Sparrow Link that sends gentle electrical pulses to nerves in the ear to help reduce opioid withdrawal symptoms. About 50 hospitalized adults with opioid use disorder will receive either the active device or a sham version, along with standard care. Researchers will see if patients use the device consistently and if it lowers withdrawal severity, pain, and cravings.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Sparrow Link device (transcutaneous auricular neurostimulation)
What this could lead to
If it works, this could offer a non-drug option to help manage opioid withdrawal symptoms in hospitals.
What could go wrong
This is a small, early feasibility study (50 people) testing whether patients will use the device at all. The sham control means any benefit may be placebo, and the device may cause discomfort or no improvement.
