Two-Arm Parallel Phase 2 Clinical Trial of Atezolizumab With or Without Low Dose Local Radiotherapy (2 x 2Gy) in Patients With Relapsed/Refractory Advanced Stage Follicular Lymphoma

The purpose of this study is to compare the safety and effects of atezolizumab with low dose
radiation on people with relapsed or refractory follicular lymphoma, In this study, the
patient will get either atezolizumab with low dose radiation or, atezolizumab alone. To be
better, the atezolizumab and low dose radiation should increase life by 1 year or more
compared to the usual approach.
