简要总结
This 2 arm study investigated the efficacy and safety of the addition of bevacizumab to the current standard of care (multimodality therapy of concurrent radiotherapy plus temozolomide followed by adjuvant temozolomide) as compared to the current standard of care alone. Participants were randomly assigned to either the bevacizumab (10 milligrams per kilogram (mg/kg) intravenously [IV] once every 2 week [q2w]) or the placebo arm, in combination with radiation therapy (total dose 60 Gray [Gy], administered as 2 Gy fractions, 5 days/week) plus temozolomide (75 milligrams per meter squared [mg/m^2] oral administration [po] daily) for 6 weeks. After a 4 week treatment break, participants continued to receive bevacizumab (10 mg/kg IV q2w) or placebo, plus temozolomide (150-200 mg/m^2 po daily on days 1-5 of each 4 week cycle) for 6 cycles of maintenance treatment or until disease progression or unacceptable toxicity, whichever occured first. Following the maintenance phase, bevacizumab (15 mg/kg iv every 3 weeks [q3w]) or placebo monotherapy continued. The time on study treatment was until disease progression.

研究组 & 干预措施
Bevacizumab + RT + Temozolomide
In the Concurrent Phase participants will receive radiotherapy (RT) in daily fractions of 2 Gy to be given 5 days per week for 6 weeks and temozolomide 75 mg/m^2 daily from the first day to the last day of radiotherapy (it may continue for a maximum of 49 days in case of delay to the end of radiation therapy) and bevacizumab 10 mg/kg IV every 2 weeks for 6 weeks. There will be a 4 week treatment break. Participants will then enter the Maintenance Phase where they receive six 28-day cycle of bevacizumab 10 mg/kg IV q2w and temozolomide 150 to 200 mg/m^2 daily in the first 5 days of each cycle. The participants will then enter the Monotherapy Phase where they will receive bevacizumab 15 mg/kg IV q3w until disease progression/unacceptable toxicity.

结局指标
主要结局
Co-Primary: Progression-free Survival (PFS) as Assessed by Investigator
时间窗: Randomization until PFS Event [Until data cutoff= 31 March 2012 (up to 31.4 months)
PFS is defined as time from randomization to disease progression (PD) or death. PD was assessed using adapted Macdonald response criteria (modified World Health Organization \[WHO\] criteria) based on 3 components: radiological tumor assessments using Magnetic Resonance Imaging \[MRI\] scans,neurological assessment and changes in corticosteroid use. PD is assessed as greater than or equal to(\>=) 25% increase in sum of products of the longest diameters of all index lesions (enhancing,measurable) compared with the smallest recorded sum (nadir); or unequivocal PD of existing non-index lesions (non-enhancing and enhancing,non-measurable); or unequivocal appearance of new lesions); or neurological worsening (if corticosteroid dose is stable or increased) compared to neurological evaluation at previous disease assessment with no need for a confirmatory scan. Participants without a PFS event were censored at last disease assessment.
Co-Primary: Overall Survival (OS)
时间窗: Randomization until OS Event (Until data cutoff= 28 February 2013 [up to 42.2 months])
Overall Survival was defined as the time from randomization to death due to any cause.
