About wearable GBM tumor therapy

About Optune®

Optune is a wearable and portable, FDA-approved treatment that has been shown in clinical trials to safely deliver continuous therapy to the area of your brain where your GBM tumor is located.

Optune delivers therapy through 4 adhesive patches, called transducer arrays. These transducer arrays are applied to your scalp and are connected to the device and battery. It is recommended that you use Optune at least 75% of the time (18 hours per day) to get the best response from treatment.

Depending on where you are in your diagnosis and treatment plan, you may need to use Optune along with another therapy or alone:

  • For people with newly diagnosed GBM, Optune is used together with the chemotherapy temozolomide, also known as Temodar®

  • For people with recurrent GBM, Optune is used alone
