Experimental drug aims to curb disinhibition in dementia patients

NCT ID NCT02534038

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a drug called AVP-786 to see if it could safely reduce disinhibition—impulsive or inappropriate behavior—in people with neurodegenerative disorders like Alzheimer's or frontotemporal dementia. The trial planned to include many participants but was terminated early after enrolling only one person. Because of this, we have very little information about whether the drug works or is safe.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

AVP-786 (deuterated dextromethorphan/quinidine)

What this could lead to

If it works, this could point toward a treatment for disinhibition symptoms in people with brain diseases like Alzheimer's or frontotemporal dementia.

What could go wrong

This trial was terminated early with only 1 participant, so results are very limited. It is unclear if the drug is safe or effective.
