Study Process

The total duration for this study is up to 36 months. The study consists of 4 periods: 

Screening Period- within 21 days prior to study entry (enrollment) ·        

Treatment Period- Once all requirements are met for participation in the study, the patient will be assigned to one of the following groups:

1. NovoTTF-100M group

Radiosurgery (SRS) radiation treatment first.

Then begin using the NovoTTF-100M device.

Along with supportive care

2. Supportive care group

Radiosurgery (SRS) radiation treatment first

Then supportive care
