  Purpose

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.

  • Overall survival rate at 9 months (OS-9) in all patients [ Time Frame: 21 months ] [ Designated as safety issue: No ]
  • Immunogenicity: anti-therapeutic antibodies (ATAs) levels [ Time Frame: 21 months ] [ Designated as safety issue: No ]
  • Overall survival in Met-positive glioblastoma patients [ Time Frame: 21 months ] [ Designated as safety issue: Yes ]
