Newly Diagnosed GBM Safety
In newly diagnosed GBM,
Optune Gio + TMZ was well-tolerated1,2
No significant increase in serious AEs compared with TMZ alone1,2

Optune Gio did not add systemic toxicity
- The most common device-related side effect with Optune Gio was mild-to-moderate skin irritation, which was typically manageable, reversible, and did not result in treatment discontinuation3
- The rate of grade 1/2 medical device site reaction was 52% for Optune Gio + TMZ compared with 0% for TMZ alone, and severe (grade 3) skin involvement occurred in 2% of patients treated with Optune Gio + TMZ2
- The overall most common (≥10%) AEs in the Optune Gio + TMZ arm were thrombocytopenia, nausea, constipation, vomiting, fatigue, asthenia, medical device site reaction, headache, convulsion, hemiparesis, and depression1,3
- A slightly higher incidence of grade 1 to 2 AEs was seen in some of the systems in the Optune Gio + TMZ arm of the study, but this is most likely a reflection of the longer duration of TMZ treatment due to the increase in PFS seen in the treatment group1
- Grade 3 to 4 AEs were well balanced between arms. None of the systemic grade 3 to 4 AEs were considered related to Optune Gio by any of the investigators1
