OPTUNE® TREATMENT FOR
GLIOBLASTOMA (GBM)
Intended for US healthcare professionals only.

In newly diagnosed GBM,

Results of a post hoc analysis of the EF-14 study showed Optune + TMZ was associated with increased median OS vs TMZ alone in patients ineligible for surgical resection1

The EF-14 pivotal phase 3 trial included patients with newly diagnosed GBM who only had a biopsy1

  • Patients who did not have a resection had a biopsy1

Extent of Resection was consistent across both study arms1

The study protocol defined surgery as surgical resection to the extent safely feasible or biopsy.1

Biopsy-only patients using Optune + TMZ had longer median OS (16.5 months) vs those using TMZ alone (11.6 months)1

  • In the EF-14 trial1
    • 13% of patients in each study arm only had a biopsy
    • 3 patients treated with Optune + TMZ and 1 patient in the TMZ alone group were included in the analysis at 48 months2

In a post hoc analysis, extension of OS was observed with Optune + TMZ across all patient subgroups vs TMZ alone1*

  • In patients who had a partial resection, median OS was 21.4 months with Optune + TMZ (n=157) compared with 15.1 months with TMZ alone (n=77)1
  • In patients who had a gross total resection, median OS was 22.6 months with Optune + TMZ (n=249) compared with 18.5 months with TMZ alone (n=123)1

Optune + TMZ improved median survival vs TMZ alone regardless of extent of resection

*A randomized, open-label trial in 695 patients with newly diagnosed GBM whose tumor was resected or biopsied and had completed concomitant radiochemotherapy were randomized 2:1 to TTFields plus maintenance TMZ or TMZ alone.

GBM, glioblastoma; OS, overall survival; TMZ, temozolomide.
