Combination of Induction Durvalumab and Tremelimumab Alone Versus Durvalumab and Tremelimumab With Chemotherapy for Potentially Resectable Pleural Mesothelioma

Summary

Objectives: The investigators will test whether combination of chemoimmunotherapy or dual agent immunotherapy alone improves efficacy for patients with MPM. Primary Objectives: The primary objective is to test whether the combination of platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves recurrence-free survival for patients with resectable MPM compared to historical, published data for surgery with chemotherapy. Secondary Objective(s): The secondary objectives are to determine the safety of and whether the platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves response rate, resectability, major pathological response, and complete pathological response. Exploratory Objective(s): The exploratory objectives are to determine the safety of and whether the platinum-based chemotherapy and pemetrexed with durvalumab / tremelimumab or durvalumab / tremelimumab alone improves response rate, resectability, major pathological response, and complete pathological response for patients with epithelioid and non-epithelioid histologies. The scientific exploratory objectives include: 1. Develop an NGS plasma assay of common mutations identified from our previous grant cycle to prospectively measure minimal residual disease (MRD) after resection as a potential, novel biomarker test in mesothelioma. 2. Determine the predictive role of BH3 profiling in patients undergoing neoadjuvant ICI followed by surgery: With patient samples collected from our neoadjuvant ICI trial, the investigators will test whether BH3 profiling from pre-treatment tumor biopsies and PBMC predicts clinical, radiological, and pathological responses to ICIs. The investigators will identify TAMs from the TiME in MPM tumor samples before and after treatment to compare differences in polarization induced by ICI in clinical and pathologically responding versus non-responding patients.
