Optune + TMZ provided an unprecedented long-term survival benefit
Survival with Optune + TMZ vs TMZ alone was significantly higher at the 2-year landmark analysis and remained higher at 5 years1,2
Overall survival (5-year survival analysis)1-3
Proven to provide the best opportunity for greater OS at 5 years vs TMZ alone (13% vs 5%)1
Median OS was significantly extended with Optune—by nearly 5 months (P<0.001)1,2
Optune + TMZ also significantly improved PFS vs TMZ alone1,2
- Median PFS: 6.7 months vs 4.0 months (P<0.001)
More time on Optune predicted increased significant survival benefit4
Median OS by monthly time (hours/day) on Optune*
*Based on the amount of time Optune was turned on and providing therapy over the course of a month. These data reflect the average patient usage of Optune for the first 6 months of treatment (months 1-6).5
†vs TMZ alone.
‡Approximation, based on percentage of usage.
†Approximation, based on percentage of usage.
‡vs TMZ alone.
- Monthly usage was a predictor of survival benefit, independent of other prognostic factors such as KPS, age, or MGMT methylation status4
86% of patients received a survival benefit from Optune because they used it more than half the time (n=388/450)4
Long-term use is supported by strong evidence

Category 1 Recommendation
for newly diagnosed GBM5
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Central Nervous System Cancers include alternating electric field therapy (Optune®) together with temozolomide (TMZ) following maximal safe resection and standard brain radiation therapy with concurrent TMZ as a Category 1 recommended treatment option for patients with newly diagnosed supratentorial GBM and good performance status. The NCCN-preferred adjuvant treatment regimen is radiation therapy with concurrent and adjuvant TMZ +/- Optune. There is uniform NCCN consensus for this recommendation based on high-level evidence (Category 1).§
5-year survival analysis was published in JAMA, December 20172
§The NCCN defines good performance as Karnofsky Performance Score (KPS) ≥60. The trial on which the IFU is based used an eligibility criteria of KPS ≥70.2,6
GBM, glioblastoma; KPS, Karnofsky Performance Score; MGMT, O-6-methylguanine-DNA methyltransferase; OS, overall survival; PFS, progression-free survival; TMZ, temozolomide.
