Optune® Novocure™

First glance at Optune®

When you or your loved one receives a GBM diagnosis, you may feel overwhelmed with information. In addition to what your healthcare team may have shared, you may be doing research yourself, and friends and family may send you things they've read.

It may be a lot to take in. But when you're ready, it's important to get organized and take the time to talk to your doctor and learn as much as you can about what treatments may work for you, including Optune.

Here are some topics that other GBM patients and their caregivers found important when learning more about Optune.

1. How would Optune fit into my treatment plan?

If you have newly diagnosed GBM and you and your doctor decide to start Optune, it would be used together with the chemotherapy temozolomide (TMZ), after you have already had surgery and radiation with TMZ.

If you have recurrent GBM and you and your doctor decide to start Optune, Optune would be used alone once treatment options like surgery and radiation have been exhausted.

2. How would I get Optune?

After talking through your treatment plan, your doctor may prescribe Optune.

It's important to note that your doctor must be certified to prescribe Optune. If your doctor is not certified, he or she may refer you to another doctor who is certified. There are certified treatment centers across the United States. You can visit Find a Treatment Center to locate one near you.

As soon as you are ready to start Optune, Novocure will connect with you to discuss insurance coverage and financial assistance, and schedule in-person device training.

3. What kind of support does Novocure offer?

nCompass™ connects patients and their caregivers with a dedicated nCompass Device Support Specialist (DSS) and access to 24/7 technical support. Your DSS will be there to provide device education, help you set up the device for the first time, answer questions, and provide information as to how you may be able to incorporate Optune into your life.

4. How will Optune fit into my daily life?

Continuous treatment with Optune can be received almost anywhere. You may be able to use Optune while you go about your daily routine at work, for some travel, and at social functions like family get-togethers. No matter where you are, it’s important that you keep the device and arrays from getting wet.

In order for Optune to work properly, you will need to keep your head shaved while using the device. However, loose-knit wigs, hats, and head coverings can all be worn over the arrays.
