A Study to Evaluate the Safety, Pharmacokinetics, and Activity of RO7496353 in Combination With a Checkpoint Inhibitor With or Without Standard-of-Care Chemotherapy in Participants With Locally Advanced or Metastatic Solid Tumors

About

Brief Summary

The purpose of this study is to evaluate the safety and tolerability of RO7496353 when administered in combination with a checkpoint inhibitor (CPI) with or without standard-of-care (SOC) chemotherapy in participants with locally advanced or metastatic solid tumors such as non-small cell lung cancer (NSCLC), gastric cancer (GC) and pancreatic ductal adenocarcinoma (PDAC). The study will be conducted in 2 stages: an initial safety run-in stage and an expansion stage.
