Brief Summary

This is a multicentric double-blind, placebo controlled, phase III trial. In this study, patients who underwent to a surgical resection of pleural mesothelioma and are without signs of macroscopic residual disease will be randomized 2:1 to receive atezolizumab or placebo. Patients will be treated for 12 months or until recurrence, unacceptable toxicity or patient/physician decision, whichever occurs first.

Randomization will be done via a centralized system and patients will be stratified histology (epithelioid vs non epithelioid) and stage (I vs
