Post-marketing experience includes spontaneous reports of cyst formation after GLIADEL® wafer implantation. These occurred at varying time intervals post-implantation. Cyst formation has also been reported in patients following resection of malignant glioma who have not had Gliadel® implanted.
The following four categories of adverse events are possibly related to treatment with GLIADEL® Wafer. The frequency with which they occurred in the randomized trials along with descriptive detail is provided below.
1. Seizures: In the initial surgery trial, the incidence of seizures was 33.3% in patients receiving GLIADEL® Wafer and 37.5% in patients receiving placebo. Grand mal seizures occurred in 5% of GLIADEL® Wafer-treated patients and 4.2% of placebo treated patients. The incidence of seizures within the first 5 days after wafer implantation was 2.5% in the GLIADEL® Wafer group and 4.2% in the placebo group. The time from surgery to the onset of the first post-operative seizure did not differ between the GLIADEL® Wafer and placebo treated patients.
