The percentage of participants surviving 24 weeks from the start of study treatment

24-week Overall Survival

The percentage of participants surviving 24 weeks from the start of study treatment without progression of disease. PFS was defined as the time from the date of study treatment initiation to the date of the first documented progression according to modified Macdonald criteria, or to death due to any cause.

24-week Progression-free Survival (PFS)

Time in months from the start of study treatment to the date of first progression according to modified Macdonald criteria, or to death due to any cause. Patients alive who had not progressed as of the last follow-up had PFS censored at the last follow-up date. Median PFS was estimated using a Kaplan-Meier curve.

Gliadel wafers (1-8) inserted at time of gross total resection. CPT-11 (Irinotecan): 125 mg/m2 (no enzyme-inducing anticonvulsant drugs) or 340 mg/m2 (enzyme-inducing anticonvulsant drugs) given every two weeks on days 1, 15, 29 of each 42 day cycle, up to 12 cycles. If the patient has the UGT 1A1 polymorphism (7/7), they do not metabolize the irinotecan normally, so these patients will start out at a two dose level reduction. For patients on an EIAED, the starting dose will be 275 mg/M2, and for patients not on an EIAED, the starting dose will be 75 mg/M2. Avastin: 10 mg/kg immediately after the irinotecan given every 2 weeks on days 1, 15, 29 of each 42 day cycle.

Median Progression-free Survival (PFS)

Time in months from the start of study treatment to date of death due to any cause. Patients alive at last follow-up are censored as of that follow-up date. Median OS was estimated using a Kaplan-Meier curve.

Median Overall Survival (OS)

Incidence and Severity of Central Nervous System (CNS) Hemorrhage

Incidence of grade ≥ 4 hematologic and ≥ grade 3 non-hematologic toxicities

Incidence of Grade ≥ 4 Hematologic and ≥ Grade 3 Non-hematologic Toxicities

Gliadel wafers (1-8) inserted at time of gross total resection. CPT-11 (Irinotecan): 125 mg/m2 (no enzyme-inducing anticonvulsant drugs) or 340 mg/m2 (enzyme-inducing anticonvulsant drugs) given every two weeks on days 1, 15, 29 of each 42 day cycle, up to 12 cycles. If the patient has the uridine diphosphate (UDP) glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) polymorphism (7/7), they do not metabolize the irinotecan normally, so these patients will start out at a two dose level reduction. For patients on an enzyme-inducing anti-epileptic drugs (EIAED), the starting dose will be 275 mg/M2, and for patients not on an EIAED, the starting dose will be 75 mg/M2. Avastin: 10 mg/kg immediately after the irinotecan given every 2 weeks on days 1, 15, 29 of each 42 day cycle.
