Patients participating in the EF-33 trial wear the device continuously but can take breaks during their daily use of the device, with average time on TTFields throughout the entire treatment period at least at 18 hours per day. The clinical trial doctor might modify the treatment schedule and use of the device as needed.
Novocure provides patients with technical support through a local Device Support Specialist (DSS). While the DSS provides comprehensive technical support, the patient’s medical team will continue to address any medical questions and to make all treatment decisions for the patient.
The use of the Optune® with High Intensity Transducer Arrays requires shaving of the scalp and continuous operation of a medical device.
Naturally, some patients may be concerned about their appearance or their lifestyle while using the device.
To address these concerns, the Optune® was carefully designed to allow patients to maintain their lifestyle without interference to their normal daily routine, such as walking outdoors, shopping, and meeting friends and family. The treating doctor can consult with Novocure ahead of time regarding any activity in question. In addition, the local DSS can provide information for lifestyle concerns.
Novocure can provide as many batteries as needed for patients who maintain an active lifestyle, which includes outdoor activities.
The transducer arrays are placed on the shaved scalp. Patients may wear head coverings, such as a loose weave wig or loose-fitting hat that allows for airflow, to cover the transducer arrays. Many options are available and financial support for the desired solution may be provided by Novocure according to the trial center’s policy and pursuant to Novocure’s approval. Patients should consult with their medical team for information about such financial support.
The wires coming out of the transducer arrays can be easily concealed underneath the patient’s clothes. By doing so, the bag carrying the device may be the only element of Optune® visible to others.
The carrying bag is provided by Novocure to each patient and can be used as a backpack, a shoulder or a side (cross-body) bag. The carrying bag blends well with mainstream bag trends.
While the total weight of the device including a battery is around 1.2 kilograms, the vast majority of patients will not be physically carrying the device most of the time, but will rather use it while it is continuously placed in one location (e.g., on a desk, a table or on the floor inside the carrying bag).
The use of the device should not interfere with household or personal electrical devices. There is no known exposure of TTFields to non-users, such as co-workers and family members.
