Ultrasound opens brain barrier to deliver Parkinson's drug in tiny trial

NCT ID NCT04370665

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

Summary

This pilot study tested whether a focused ultrasound device could temporarily open the blood-brain barrier to deliver the drug Cerezyme into the brains of 4 people with Parkinson's disease. The main goal was to see if the procedure was safe and could successfully get the drug into a specific brain region. Because it is a very early, small study, it does not yet show whether this approach helps Parkinson's symptoms.

What this could mean

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

Active substance

Cerezyme (imiglucerase)

What this could lead to

If this works, it could show a new way to deliver drugs directly to the brain for Parkinson's disease.

What could go wrong

This is a very small pilot study with only 4 participants, focused on safety and feasibility. It is too early to know if it will improve symptoms or change the course of the disease.
