| E.2.1 | Main objective of the trial |
Stage 1
• To evaluate the safety and tolerability of Polatuzumab vedotin (Pola) -R-GemOx as a combination therapy on basis of incidence, nature and severity of physical findings and adverse events (AEs)), with a specific focus on peripheral neuropathy, according to the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5 (NCI CTCAE v5.0)
