Optune Gio works by creating Tumor Treating Fields (TTFields), which are electric fields that disrupt cancer cell division. Using 4 adhesive patches called transducer arrays, TTFields therapy is delivered right into the area of your body where the cancer is located. TTFields may destroy some cancer cells completely and have not been shown to significantly affect healthy cells. Learn more about how Optune Gio works.
If you have newly diagnosed GBM, Optune Gio is used together with a chemotherapy called temozolomide (TMZ) if:
- Your cancer is confirmed by your doctor AND
- You have had surgery to remove as much of the tumor as possible
If your tumor has come back, Optune Gio can be used alone as an alternative to standard medical therapy if:
- You have tried surgery and radiation and they did not work or are no longer working AND
- You have tried chemotherapy and your GBM has been confirmed by your healthcare professional
Arrays need to be applied directly to your scalp to work properly. Even a small amount of hair growth can prevent the arrays from making good contact with your scalp. Arrays should be changed at least 2 times per week (one set of arrays should not be worn for more than 4 days at a time). Learn more about how Optune Gio works.
Loose-knit wigs, hats, and other head coverings may be worn over the arrays. Learn more about Optune Gio.

A large clinical study showed that Optune Gio should be worn for at least 75% of the time (18 hours per day). This will help you get the best response from treatment.
When you begin treatment with Optune Gio, work with your doctor to decide how long you should stay on Optune Gio based on your needs. After starting Optune Gio, it may take time to see whether it is working. You and your doctor can review how Optune Gio is working on your tumor and how it is fitting into your lifestyle. This will help you decide on the best path forward. The clinical study of newly diagnosed GBM patients showed that ongoing and continued use of Optune Gio provides the best chance for lasting benefits. Learn more about how Optune Gio may help.
