A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase II Study Evaluating the Efficacy and Safety of Onartuzumab (MetMAb) in Combination With Bevacizumab or Onartuzumab Monotherapy in Patients With Recurrent Glioblastoma

This randomized, double-blind, placebo-controlled, multicenter phase II study will evaluate the safety and efficacy of onartuzumab (MetMAb) in combination with bevacizumab as compared to bevacizumab alone and of onartuzumab as monotherapy in patients with recurrent glioblastoma. Patients will be randomized 1:1:1 to receive either placebo plus bevacizumab every 3 weeks, or onartuzumab plus bevacizumab, or onartuzumab plus placebo. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.
