A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase II Study Evaluating the Efficacy and Safety of Onartuzumab 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 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.
Stanford is not currently accepting new patients for this trial. You may want to check clinicaltrials.gov to see if other locations are recruiting.
