More time on Optune predicted increased significant survival benefit4
Median OS by monthly time (hours/day) on Optune*
‡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
Alternating electric fields (Optune)
for newly diagnosed GBM
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Central Nervous System Cancers include alternating electric fields (Optune) as a Category 1 Preferred regimen, following maximal safe resection if feasible, or else biopsy and standard radiation therapy with concurrent and adjuvant TMZ, for patients aged ≤70 years with newly diagnosed supratentorial GBM and good performance status§ regardless of MGMT promoter status.
There is uniform NCCN consensus for this recommendation based on high-level evidence (Category 1), and superior efficacy, safety, evidence, and when appropriate, affordability (Preferred).6
5-year survival analysis was published in JAMA, December 20172

Indications for Use
Optune is intended as a treatment for adult patients (22 years of age or older) with histologically-confirmed glioblastoma multiforme (GBM).
Optune with temozolomide is indicated for the treatment of adult patients with newly diagnosed, supratentorial glioblastoma following maximal debulking surgery, and completion of radiation therapy together with concomitant standard of care chemotherapy.
Important Safety Information
Do not use Optune in patients with an active implanted medical device, a skull defect (such as, missing bone with no replacement), or bullet fragments. Use of Optune together with implanted electronic devices has not been tested and may theoretically lead to malfunctioning of the implanted device. Use of Optune together with skull defects or bullet fragments has not been tested and may possibly lead to tissue damage or render Optune ineffective.
Do not use Optune in patients that are known to be sensitive to conductive hydrogels. In this case, skin contact with the gel used with Optune may commonly cause increased redness and itching, and rarely may even lead to severe allergic reactions such as shock and respiratory failure.
Warnings and Precautions
The most common (≥10%) adverse events involving Optune in combination with temozolomide were thrombocytopenia, nausea, constipation, vomiting, fatigue, medical device site reaction, headache, convulsions, and depression.
If the patient has an underlying serious skin condition on the scalp (e.g. ulcers, open wound, broken skin) evaluate whether this may prevent or temporarily interfere with Optune treatment.
Use of Optune in patients with an inactive implanted medical device in the brain has not been studied for safety and effectiveness, and use of Optune in these patients could lead to tissue damage or lower the chance of Optune being effective.
Do not prescribe Optune for patients that are pregnant, you think might be pregnant or are trying to get pregnant, as the safety and effectiveness of Optune in these populations have not been established.
Optune can only be prescribed by a healthcare provider that has completed the required certification training provided by Novocure (the device manufacturer).
