Brief Summary:

This study is a multicenter phase II trial which primary objective is to assess the anti-lymphoma activity of atezolizumab associated with a BCL-2 inhibitor (GDC-199, venetoclax) and an anti-CD20 monoclonal antibody (obinutuzumab) in three separate cohorts:

  • relapsed/refractory follicular lymphoma (FL) patients
  • relapsed/refractory aggressive (DLBCL) lymphoma patients
  • relapsed/refractory other indolent (iNHL) lymphoma patients (MZL and MALT)
