Trial Outcomes & Findings for A Study of Bevacizumab and Extended Treatment of Temozolomide in Patients With Recurrent Glioblastoma Multiforme (NCT NCT01115491)

NCT ID: NCT01115491

Last Updated: 2014-12-08

Results Overview

PFS was defined as the time, in weeks, from the date of inclusion in the study to the date of the first documentation of disease progression or death of the participant due to any cause. Participants that did not have an event at the time the analysis was performed were censored at the date of last contact. Participants that began a treatment other than those planned in this study (bevacizumab or temozolomide) were censored on the start date of the new treatment.

Measure
Bevacizumab + Temozolomide
Cycles 1-12 (4-week cycles): Participants received bevacizumab 10 milligrams per kilogram (mg/kg) intravenously (IV) on Days 1 and 15 (followed by 2 weeks off); temozolomide 150 mg per square meter (mg/m\^2), orally (PO), on Days 1 through 7 and on Days 15 through 21 (followed by 1 week off). Cycle was repeated for a maximum of 12 cycles. Cycle 13 and beyond (4-week cycles): If the first 12 cycles were tolerated with no disease progression, participants then received bevacizumab 10 mg/kg IV on Days 1 and 15 (followed by 2 weeks off). This cycle was repeated every 28 days until disease progression.

Population: ITT population

Overall response was defined as the percentage of participants who obtained CR or PR using adapted MacDonald criteria. CR: disappearance of all index and non-index lesions, confirmed no less than 4 weeks after assessment, no evidence of disease progression; corticosteroid dosage at or below 20 mg hydrocortisone daily; no neurological changes or an improvement as compared to last disease assessment. PR was defined as: Fifty percent or greater decrease in the sum of products of the larger diameter and the larger perpendicular diameter of all index lesions confirmed no less than 4 weeks after assessment, no evidence of disease progression and the absence of progressive, or non-evaluable disease status for non-index legions; unchanged, or decreased corticosteroid dose as compared to the last disease assessment; no neurological changes or an improvement as compared to the neurological examination at last disease assessment.
