Overview
Brief Summary
This is a phase II, multicenter, open-label study to evaluate the antitumor activity, efficacy and safety of GEN-001 in combination with avelumab as a third line (3L) or greater line treatment which is not received the Standard of Care (SOC) for patients with PD-L1 positive advanced GC/Gastroesophageal Junction Adenocarcinoma who are not received cancer immunotherapy regimens as mono or combination therapy.
