General information about the trial
|
|||
Main objective of the trial |
The primary objective was to assess the efficacy of bevacizumab in terms of the 6-month overall survival rate (OS-6), measured from the beginning of study drug administration to the death of the participant from any cause.
|
||
Protection of trial subjects |
The study was conducted in accordance with the principles of the “Declaration of Helsinki” and Good Clinical Practice (GCP) and investigators were trained according to applicable Sponsor standard operating procedures (SOPs).

Overall survival (OS) was defined as the time in months from the start of treatment to death due to any cause. If a participant was not known to have died, time was censored at the last date the participant was known to be alive, which was defined as the latest among date of last visit, date of last sample collected for laboratory exam, date of magnetic resonance imaging (MRI) assessment, date of last treatment, date of discontinuation, and date of last available follow-up visit. Participants with no information after baseline were censored at Day 1. OS was estimated by the Kaplan-Meier method. Analysis was performed on intent-to-treat (ITT) population defined as all randomized participants with at least one administration of the study drug.

Percentage of Participants Who Were Alive and Progression Free 6 Months After Start of Treatment | ||||||||||||
End point description |
Progression-free survival (PFS) was defined as the time in months from the start of treatment to the date of the first occurrence of disease progression or death from any cause, whichever occurred first. PFS was estimated by the Kaplan-Meier method. Progression was assessed using Response Assessment in Neuro-Oncology (RANO) or the Macdonald Response Criteria, whichever occurred first. As per the RANO criteria, progression was defined as 25 percent (%) or more increase in enhancing lesions despite stable or increasing steroid dose; increase (significant) in non-enhancing T2/FLAIR lesions, not attributable to other non-tumor causes; any new lesions; and clinical deterioration (not attributable to other non-tumor causes and not due to steroid decrease). As per the Macdonald criteria, progression was defined as 25% or more increase in enhancing lesions; any new lesions; and clinical deterioration. Analysis was performed on ITT population.

Percentage of Participants With a Best Overall Response of Complete Response (CR) or Partial Response (PR) | ||||||||||||||||||
End point description |
Percentage of participants achieving CR or PR as overall response between first drug administration and documented disease progression were calculated. Tumor response was evaluated according to both, the RANO and the Macdonald response criteria. As per Macdonald criteria, CR was defined as the disappearance of all enhancing disease, sustained for at least 4 weeks, and no new lesions along with clinical features of clinically stable or improved, with no corticosteroid; PR was defined as a 50% or more decrease of all measurable enhancing lesions, sustained for at least 4 weeks, and no new lesion along with clinical features of clinically stable or improved, with stable or reduced corticosteroids. RANO criteria defined CR and PR the same as Macdonald criteria with the following additions: CR - improved non enhancing T2/FLAIR lesions; PR - no progression of non-measurable disease, stable or improved non enhancing FLAIR/T2 lesions. Analysis was performed on ITT population.

EORTC QLQ-C30: included global health status/quality of life (QOL), functional scales (physical, role, cognitive, emotional, and social), symptom scales (fatigue, pain, nausea/vomiting), and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, and financial difficulties). Most questions used a 4- point scale (1 ‘Not at All’ to 4 ‘Very Much’); 2 questions used a 7-point scale (1 ‘Very Poor’ to 7 ‘Excellent’). Scores were averaged and transformed to a 0-100 scale; a higher score for Global Qol/functional scales indicates better level of QoL/functioning, or a higher score for symptom scale indicates greater degree of symptoms. Analysis was performed on ITT population and included only participants with evaluable data. The number 99999 signifies data not available either because no participant was evaluable (when 99999 is reported for both mean and standard deviation) or only one participant was evaluable (when 99999 is reported only for standard deviation).

Amendment |

01 Jan 2013 |
Clarified the exclusion criteria; “previous treatment with bevacizumab or other anti-angiogenic drugs” was modified into “no prior treatment with bevacizumab or other vascular endothelial growth factor (VEGF) inhibitors or VEGF receptor signaling inhibitors here. Provided more time to perform magnetic resonance imaging (MRI) at baseline prior to randomization. Provided clear instructions about the determination of proteinuria by dipstick; this exam was required only for the participants treated with bevacizumab and not for those treated with fotemustine. Added an acronym to the study. |

01 Sep 2013 |
Clarified the definition of database (DB) lock and end of study; the previous definition was modified into “follow up for survival will continue until 14 months after the randomization of the last participant or all participants have died whichever occurs first”. Amended the inclusion criteria; “Histologically confirmed recurrent glioblastoma multiforme (Grade IV)” was amended into “Histologically confirmed glioblastoma multiforme (Grade IV)”. The definition of follow-up period was changed to 14-months following randomization to provide additional information about the safety of Avastin not available at the time of first submission and first amendment. Adapted the time of serious adverse event (SAE) reporting in accordance with the latest safety directives. |
