Sound waves may help deliver cancer drugs to the brain

NCT ID NCT03714243

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a device that uses focused ultrasound can safely and temporarily open the blood-brain barrier in people with HER2-positive breast cancer that has spread to the brain. Eight participants received the procedure, and researchers checked for side effects and whether the barrier actually opened. The goal was to see if this approach is safe enough to explore further for delivering cancer treatments directly to brain tumors.

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

Active substance

ExAblate focused ultrasound device

What this could lead to

If it works, this could offer a new way to deliver treatments directly to brain tumors without surgery or radiation.

What could go wrong

This was a very small early study (8 people) focused only on safety and feasibility. It does not prove the treatment works against cancer.
