Quick facts about Optune


Optune is a noninvasive, portable device that is classified as durable medical equipment (DME).


Optune provides continuous action against disease progression by delivering electrical fields to disrupt biological processes in dividing cancer cells.

Transducer arrays are applied to the shaved scalp and must be changed at least 2 times per week (every 4 days, at most)
- Arrays should always have good scalp contact
- Note: Avoid activities that may result in the device or transducer arrays becoming wet. Getting the device wet may cause it damage
Recommended usage goal for Optune is 18+ hours/day, which gives patients flexibility to decide which times of day are best for use4

Patients can benefit most from wearing Optune for the recommended time
- In the phase 3 pivotal trial, 75% of patients used Optune 18 or more hours a day during the first 3 months of treatment5
- 50% daily use was the threshold for significant survival benefit over TMZ alone
- 86% of patients received a survival benefit from Optune, because they used it more than half the time (n=388/450)
