Several studies have assessed the activity of bevacizumab
when added to chemotherapy in ovarian cancer. In Europe, bevacizumab is
approved by the European Medicines Agency in combination with
carboplatin and paclitaxel in newly diagnosed ovarian cancer, with
carboplatin and gemcitabine in platinum-sensitive relapse ovarian
cancer, and with chemotherapy in platinum-resistant relapse ovarian
cancer. In the USA, bevacizumab is approved by the Food and Drug
Administration when combined with chemotherapy for platinum-resistant
relapse ovarian cancer. These approvals were based on progression-free
survival improvements, but so far no overall survival benefit has been
noted with the addition of bevacizumab to chemotherapy in any overall
study population.2, 3, 4, 5
In The Lancet Oncology, Amit Oza and colleagues1
report the mature overall survival data from ICON7, an open-label
randomised phase 3 trial comparing bevacizumab plus six 3-weekly cycles
of carboplatin and paclitaxel chemotherapy followed by bevacizumab
maintenance versus the carboplatin and paclitaxel chemotherapy regimen
alone. The study participants were patients with newly diagnosed ovarian
cancer following cytoreductive surgery or patients with advanced-stage
disease who had no further surgery planned.1 The primary endpoint of this trial, progression-free survival, has been reported previously.2 Concordant with the results of GOG-218,3 another phase 3 trial comparing chemotherapy and bevacizumab versus chemotherapy alone in upfront therapy for ovarian cancer.....References
