Optune should be worn for at least 75% of the time (18 hours per day) to get the best response from treatment.
When you begin treatment with Optune, work with your doctor to make your own individualized plan about how long you should stay on Optune. After starting Optune, it may take time to see whether it is working. You and your doctor can review how Optune is working against your tumor and fitting into your lifestyle, to determine the best path forward. It is important to note that ongoing and continued use of Optune will provide the best chance for ongoing benefits as seen in the clinical study of newly diagnosed GBM patients.
As long as the device and TTFields are turned on, therapy is being delivered. Optune records the amount of time that therapy is delivered per day. Your healthcare team will receive a monthly report to monitor your treatment goals.
If your current physician is not a certified Optune prescriber, it is possible to have your care coordinated with another center. Novocure will work with your existing healthcare team so you will not be asked to switch doctors.
Yes. Optune is a wearable, portable, FDA-approved device indicated to treat a type of brain cancer called glioblastoma muliforme (GBM) in adult patients 22 years of age or older.
If you have newly diagnosed GBM, Optune is used together with a chemotherapy called temozolomide (TMZ) if your cancer is confirmed by your healthcare professional and you have had surgery to remove as much of the tumor as possible.
If your tumor has come back, Optune 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.
Please ask your doctor before engaging in physical activity, to ensure that it is safe for you and appropriate while using Optune. It’s important that you keep the device and arrays from getting wet. More frequent array changes may be needed if you’ve performed a physical activity that causes you to sweat more.
Optune was not tested in pregnant women. Do not use Optune if you are pregnant, think you might be pregnant, or are trying to get pregnant. Women who are able to get pregnant must use birth control when using the device. It is unknown what side effects the device may cause to a pregnant woman, or if it will be effective. For more information, please discuss this with your healthcare provider.

Some warming sensation can be expected while using Optune. Most people get used to this quickly. If you are especially uncomfortable or experience a rash, sores, or skin ulcers on your scalp, contact your healthcare provider. As with any treatment, if you notice any change in your health, please contact your healthcare provider immediately.
Optune has an internal fan that helps it from overheating. The carrying bag that comes with the device has been designed to allow for proper airflow. Other bags should not be used.
Yes. Optune has been designed and tested not to interfere with other electronic devices according to international standards, and we have seen no problems with using mobile devices while on treatment.
No. Optune is portable and battery operated, but it is not designed to be plugged into a car charger. Remember, if you plan to be out for more than 2 hours, carry an extra battery or the power supply with you, in case the current battery runs out. If you do not take a spare battery or power supply, you may have a break in treatment, which can reduce the therapy’s effectiveness.
Consult with your healthcare provider regarding your ability to drive a car.

Getting the transducer arrays wet can cause the patches to come loose and interfere with their contact with the scalp. If this happens, the alarm may beep and the device may turn off. Any time the transducer arrays become wet or loosen, they should be changed. To prevent the transducer arrays from getting wet, cover them with a shower cap when bathing or showering, and leave the device outside of the bathroom. In rainy weather use a hat or umbrella to prevent arrays from getting wet.
Transducer arrays should be changed at least 2 times per week (every 4 days at most), depending upon factors like how quickly your hair grows or how much you sweat. As your hair grows, it prevents the transducer arrays from making good contact with your scalp. You'll know it's time to change the transducer arrays when the alarm beeps more often.
Yes. Turn the system off and remove the arrays before having x-rays, CT scans, or MRIs. The device should not be exposed to high radiation, and leaving the arrays on during the procedure can interfere with the image results. After the procedure is completed, apply new transducer arrays and connect Optune.
Please call nCompass at 1-855-281-9301 (toll free) to speak with a technical support representative if your device is damaged. All technical service must be performed by qualified, trained personnel. If you attempt to open the system, you could cause damage or receive an electric shock.
