Atezolizumab, Pemetrexed Disodium, Cisplatin, and Surgery With or Without Radiation Therapy in Treating Patients With Stage I-III Pleural Malignant Mesothelioma

Overview

About this study

To evaluate if the regimen of neoadjuvant cisplatin-pemetrexed-atezolizumab, surgery +/- radiation, then maintenance atezolizumab is feasible and safe (as defined in Section 11.1) for patients with resectable malignant pleural mesothelioma.

a. To evaluate progression free survival (both by RECIST 1.1 and also using a Modified RECIST for Pleural Tumors) in patients with resectable malignant pleural mesothelioma treated with a regimen of neoadjuvant cisplatin-pemetrexed-atezolizumab, surgery +/- radiation, followed by one year of maintenance atezolizumab.

b. To evaluate overall survival in patients with resectable malignant pleural mesothelioma treated with a regimen of neoadjuvant cisplatin-pemetrexed-atezolizumab, surgery +/- radiation, followed by one year of maintenance atezolizumab.

c. To evaluate response rate (confirmed and unconfirmed, complete and partial, both by RECIST 1.1 and also using a Modified RECIST for Pleural Tumors) in the subset of this patient population with measurable disease.

a. To evaluate the association between immunohistochemical (IHC) expression of PD-L1 in tumors and clinical outcomes in mesothelioma patients treated with trimodality/bimodality therapy including atezolizumab (anti-PD-L1).

b. To evaluate the association between expression of immune-related genes identified by Immune Nanostring (depending on RNA availability) and clinical outcomes in mesothelioma patients treated with trimodality/bimodality therapy including atezolizumab.

c. To evaluate the association between multiplex immunofluorescence (IF) of up to 10 immune markers in two panels and clinical outcomes in mesothelioma patients treated with trimodality/bimodality therapy including atezolizumab.
