Brief Summary:

This randomized, double-blind, placebo-controlled, multicenter phase II study will evaluate the safety and efficacy of onartuzumab in combination with bevacizumab as compared to bevacizumab alone in participants with recurrent glioblastoma. Participants will be randomized 1:1 to receive either placebo plus bevacizumab every 3 weeks, or onartuzumab plus bevacizumab. Study treatment will continue until disease progression, unacceptable toxicity, participants or physician decision to discontinue, or death.
