This study will test the hypothesis that prolonged adjuvant Temozolomide (TMZ) may delay relapses in patients with glioblastoma compared to the standard care consisting in observation with brain MRI every 3 months and rechallenging with TMZ at relapse (Stop and Go arm).

Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

  12. All patients (male and female) with reproductive potential must use effective contraception. Females must have a negative serum pregnancy test at entry to study.
  13. Signed informed consent from the patient or legal representative must be obtained.
