Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with newly diagnosed GBM who have completed initial radiochemotherapy and are starting maintenance TMZ.

Probably not a fit

Patients currently participating in other clinical trials or those with significant neurological diseases may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective multicenter non-interventional study aims to confirm the survival benefit of the Optune Gio® device in patients with newly diagnosed Glioblastoma (GBM) who have completed radiotherapy and concomitant temozolomide (TMZ). The study will measure overall survival (OS) and progression-free survival (PFS), as well as device usage compliance and its impact on quality of life (QoL) in a real-life setting. Participants will be monitored for their daily life experiences and symptom burden, given the aggressive nature of GBM and its associated disabilities.

Why it matters

Potential benefit: If successful, this study could provide evidence for improved survival and quality of life for patients with newly diagnosed GBM using the Optune Gio® device.

How similar studies have gone: Previous studies have shown success with similar approaches, particularly the pivotal phase III trial that led to the FDA approval of Optune Gio®.
