Docetaxel plus bavituximab or placebo
DrugPatients will be randomized to receive docetaxel plus placebo, docetaxel plus 1 mg/kg bavituximab, or docetaxel plus 3 mg/kg bavituximab in the Combination Therapy Period. The Combination Treatment Period for each patient will begin on Study Day 1. Docetaxel, 75 mg/m2, will be given on Day 1 of each 21 day cycle for up to 6 cycles, and placebo or the assigned dose of bavituximab will be given weekly. Docetaxel administration will occur every 21 days. All patients who complete the Combination Therapy Period (or discontinue for any reason other than disease progression or toxicity) will be eligible to enter the Monotherapy Period. Patients will continue to receive assigned blinded treatment (placebo or 1 or 3 mg/kg bavituximab) weekly until progression or toxicity.
