Brief Summary
The aim of this Phase III study is to evaluate the superiority of dose-dense temozolomide (ddTMZ) followed by bevacizumab at ddTMZ failure for glioblastoma at first recurrence or progression, comparing to bevacizumab alone.

Outcome Measures
Primary Outcomes (1)
Overall survival
Overall survival will be measured from registration until death for any reason. If the patient is alive at last follow-up, the patient will be censored at the last time of confirmation of survival.
Time to event. Up to 2 years from the last patient in.
Secondary Outcomes (11)
Progression-free survival (PFS)
Time to event. Up to 2 years from the last patient in.
6-month progression-free survival (6m-PFS)
6 months from registration
Complete response rate
Through study completion, an average of 1 year
Response rate
Through study completion, an average of 1 year
Adverse events
Up to 1 year after completion/termination of the protocol treatment.
- +6 more secondary outcomes
Study Arms (2)
Bevacizumab (BEV) alone
ACTIVE COMPARATORBevacizumab 10 mg/kg, day 1 div, every 2 weeks
Dose Dense Temozolomide Followed by BEV
EXPERIMENTALTemozolomide (120 mg/m2, po, 7 days on/7 days off, every 2 weeks per cycle) up to 48 cycles. The dose will be escalated to 150 mg/m2 at 3rd cycle if the defined conditions are met throughout the first 2 cycles. At recurrence or progression, bevacizumab alone(10 mg/kg, day 1 div, every 2 weeks)
Interventions
Eligibility Criteria
You may qualify if:
- Histologically proven diagnosis of glioblastoma (including giant cell glioblastoma and gliosarcoma) by WHO2007 criteria.
- For patients who did not undergo surgery for recurrent disease; pre-registration contrast MRI should confirm; (i)progressive or recurrent glioblastoma; (ii)no evidence of acute or subacute cerebral hemorrhage at enrolment; (iii)presence of a measurable lesion.
- For patients who underwent surgery for recurrent disease; (i)progressive or recurrent glioblastoma must be confirmed on contrast MRI before reoperation; (ii)glioblastoma or anaplastic astrocytoma must be histologically identified in the tissue resected at reoperation; (iii)presence of measurable lesions is not mandatory on pre-registration contrast MRI (more than 4 days after reoperation); (iv)no MRI evidence of aggravating cerebral hemorrhage.
- No evidence of tumors in the cerebellum, brain stem, optic nerve, olfactory nerve, and pituitary gland.
- No evidence of meningeal dissemination or gliomatosis cerebri.
- Prior treatment for newly-diagnosed glioblastoma (or diffuse astrocytoma (Grade II) or anaplastic astrocytoma (Grade III)) with postoperative TMZ administered concomitantly with radiotherapy (\>=54 Gy for \<=69 years old; \>=30 Gy for \>=70 years old) and at least for two cycles (5/28d) as an adjuvant treatment have been given.
- No history of prior treatment with stereotactic radiotherapy (ex. Gamma-knife/Cyberknife), proton beam irradiation, neutron capture therapy, and chemotherapies except standard dose TMZ and immunotherapy (vaccines, immune checkpoint inhibitors, antibodies etc.), bevacizumab (12 weeks or more after termination of prior upfront bevacizumab use) that were combined with TMZ, and intraoperative placement of carmustine wafers, for glioblastoma (including diffuse astrocytoma (Grade II) and anaplastic astrocytoma (Grade III) at onset) diagnosed with WHO2007 criteria.
- Time periods required from the last day of the prior treatment indicated at registration.
- ①Peptide vaccination, immune checkpoint inhibitors, antibodies: 4 weeks.
- ②Bevacizumab: 12 weeks.
- More than 90 days after completion of radiotherapy. For those who underwent reoperation, between 21 and 28 days postoperatively.
- Age between 20 and 75 years at enrolment.
- Karnofsky Performance Status \>= 60 within 14 days before enrolment.
- No prior treatment with chemotherapy, molecular targeted therapy, or radiotherapy to head and neck area for other malignancies.
- Adequate organ function.
- +1 more criteria
You may not qualify if:
- Synchronous or metachronous (within 5 years) malignancy, except for carcinoma in situ or mucosal tumors curatively treated with local therapy
- Active infection requiring systemic therapy

- Uncontrolled diabetes mellitus
- Unstable angina within 3 weeks, with a history of myocardial infarction within 6 months, or New York Heart Association (NYHA) class II or greater congestive heart failure
- Inadequately controlled hypertension (cannot be controlled to a systolic pressure of \>= 150 mmHg and a diastolic pressure of \>= 100 mmHg)
- History of symptomatic cerebrovascular disorder (including subarachnoid hemorrhage, cerebral infarction and transient ischemic attack) within 6 months or history of vascular disorder requiring intervention (including venous/arterial thrombosis or embolism and aortic aneurysm) within 6 moths
- History of grade \>= 2 hemoptysis within 28 days
- History of hemorrhagic tendency (e.g., coagulation disorder) or any grade \>= 3 hemorrhage within 28 days
- History of gastrointestinal perforation, fistula, abdominal abscess or uncontrolled peptic ulcer within 6 months
