Patients participating in the study wear the device continuously but can take breaks during their daily use of the device, as long as the average time on TTFields throughout the entire treatment period is kept at 18 hours per day. The treating doctor might modify the treatment schedule and use of the device as needed.

Novocure provides patients with around the clock 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 NovoTTF-100L(O) device involves the continuous operation of a medical device, which may be carried inside a bag provided with the device. The device bag blends well with mainstream bag trends and can be used as a backpack, a shoulder or a side (cross-body) bag. Alternatively, a trolley can be used to carry the device. The transducer arrays placed on the torso can be completely covered underneath patient’s clothes and be invisible to others. Therefore, the bag carrying the device may be the only element of the NovoTTF-100L(O) treatment kit visible to others.

The NovoTTF-100L(O) was carefully designed to allow patients to maintain their lifestyle without interference to their daily routines such as walking outdoors, shopping, and meeting friends and family. The treating doctor can be consulted ahead of time regarding any specific activity in question. In addition, the local DSS can provide information to address lifestyle concerns.

Novocure can provide as many portable batteries as needed for patients who maintain an active lifestyle, which can include outdoor activity.

While the total weight of the treatment kit including a battery is around 3 kilograms or 6 pounds, the vast majority of patients are not expected to be physically carrying the device most of their 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 exposure of TTFields to non-users, such as co-workers and family members.
