Study Design
- Primary endpoint: overall survival from the time of polymer implantation.
- The follow-up period was up to 71 months.
- Patients included in this study were eligible for systemic chemotherapy.
- Additional eligibility criteria included: completion of external beam radiation therapy; no nitrosureas for 6 weeks and no other systemic chemotherapy for 4 weeks prior to enrollment.
- This study was the basis for the first FDA-approved indication of GLIADEL Wafer.1

- Efficacy
20% MORE PATIENTS SURVIVED AT 6-months with gliadel wafer.1
Median survival of GBM patients (n=145) increased by 41% from 18.4 weeks (4.6 months) with placebo to 25.9 weeks (6.5 months) with GLIADEL Wafer treatment
