Randomized Phase II Evaluation of Bevacizumab Versus Bevacizumab Plus Fosbretabulin in Recurrent Ovarian, Tubal, or Peritoneal Carcinoma: An NRG Oncology/Gynecologic Oncology Group Study.

Purpose: The vascular disrupting agent fosbretabulin tromethamine selectively targets pre-existing tumor vasculature, which causes vascular shutdown and leads to cancer cell death and necrosis. Antiangiogenesis agents such as bevacizumab, a humanized antivascular endothelial growth factor monoclonal antibody, might prevent revascularization during and after treatment with a vascular disrupting agent.

Patients And Methods: Patients with recurrent or persistent epithelial ovarian, tubal, or peritoneal carcinoma, measurable or detectable disease, and three or fewer prior regimens were randomly assigned to bevacizumab (15 mg/kg intravenously once every 3 weeks) or the combination of bevacizumab (15 mg/kg) plus fosbretabulin (60 mg/m(2)) intravenously once every 3 weeks until disease progression or toxicity.

Weekly vs. Every-3-Week Paclitaxel and Carboplatin for Ovarian Cancer.

Background: A dose-dense weekly schedule of paclitaxel (resulting in a greater frequency of drug delivery) plus carboplatin every 3 weeks or the addition of bevacizumab to paclitaxel and carboplatin administered every 3 weeks has shown efficacy in ovarian cancer. We proposed to determine whether dose-dense weekly paclitaxel and carboplatin would prolong progression-free survival as compared with paclitaxel and carboplatin administered every 3 weeks among patients receiving and those not receiving bevacizumab.

Methods: We prospectively stratified patients according to whether they elected to receive bevacizumab and then randomly assigned them to receive either paclitaxel, administered intravenously at a dose of 175 mg per square meter of body-surface area every 3 weeks, plus carboplatin (dose equivalent to an area under the curve [AUC] of 6) for six cycles or paclitaxel, administered weekly at a dose of 80 mg per square meter, plus carboplatin (AUC, 6) for six cycles.
