Prior neoadjuvant chemotherapy was permitted. After debulking surgery, patients received bevacizumab 15 (or 7.5) mg/kg every 3 weeks (q3w) with 4 to 8 cycles of paclitaxel (investigator’s choice of 175 mg/m2 q3w or 80 mg/m2 weekly) plus carboplatin AUC 5 to 6 q3w. Single-agent bevacizumab was continued until progression or for up to 24 months. The primary end point was safety.Results Between December 2010 and May 2012, 1021 patients from 35 countries began study treatment. Bevacizumab was administered at 15 mg/kg in 89% of patients and for more than 15 months in 53%. Median follow-up duration was 32 months (range, 1–50 months). The most common all-grade adverse events were hypertension (55% of patients), neutropenia (49%), and alopecia (43%). The most common grade 3 or higher-grade adverse events were neutropenia (27%) and hypertension (25%). Bevacizumab was discontinued because of proteinuria in 5% of patients and hypertension in 3%. Median progression-free survival (PFS) was 25.5 months (95% confidence interval, 23.7–27.6 months).Conclusion Extended bevacizumab demonstrated increased incidences of proteinuria and hypertension compared with 12 or 15 months of bevacizumab in previous trials, but these rarely led to bevacizumab discontinuation. Median PFS is the longest reported for frontline bevacizumab-containing therapy. The longer bevacizumab duration beyond 15 months in this study may improve PFS without substantially compromising safety. ER -
