Study of the PD-L1 Inhibitor Atezolizumab With or Without Low-dose, Local Radiation in Patients With Relapsed or Refractory Advanced Stage Follicular Lymphoma

Overview

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.

  • For female patients of childbearing potential and male patients with partners of childbearing potential, agreement (by patient and/or partner) to use highly effective form(s) of contraception (i.e., one that results in a low failure rate [< 1% per year] when used consistently and correctly) and to continue its use for 5 months after the last dose of ATEZOLIZUMAB.
