Electric field helmet tested for tough brain tumor – but only one patient tried it

NCT ID NCT03450850

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a wearable device called NOVOTTF-200A in people with recurrent Grade III astrocytoma, a type of brain cancer. The device delivers low-intensity electric fields to the brain to slow tumor growth. Only 1 participant was enrolled, and the main goal was to see if the tumor stopped growing for six months. Because of the tiny sample size, the results are very limited and cannot tell us if the device truly works.

What this could mean

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

Active substance
NOVOTTF-200A (a wearable device that delivers electric fields to the brain to slow tumor growth)
What this could lead to
If it works, this device could offer a new way to control tumor growth in patients with recurrent Grade III astrocytoma without using chemotherapy or other drugs.
What could go wrong
This trial enrolled only 1 person, so results cannot be generalized. The device must be worn at least 18 hours a day, which may be burdensome, and side effects or lack of benefit are possible.
