Study Design
- Primary endpoint: Overall survival among all patients with newly diagnosed high-grade glioma, the primary outcome measure, was prolonged in the Gliadel arm.
- Exclusion criteria: Prior cytoreductive therapy or radiotherapy to the brain, multifocal disease, or clinically significant laboratory abnormalities.
- Patients were followed for at least 3 years or until death.
- For all patients except those with anaplastic oligodendroglioma, systemic chemotherapy was not allowed until recurrence.
- This study was the basis for the second FDA-approved indication of GLIADEL Wafer1

- Efficacy
Survival Was Extended in Newly-Diagnosed HGG Patients
The use of GLIADEL Wafer during initial surgery resulted in1,2:
• 2.3 month survival advantage (P<0.05)
• 27% reduction in risk of death (HR=0.73, P=0.02; 95% CI, 0.56-0.95)
