What this Trial Is About

The goal of this study is to learn about of the research study drug, telomelysin (OBP-301), in combination with pembrolizumab in advanced or metastatic gastric or gastroesophageal junction (GEJ) cancer. The main question it aims to answer is whether this combination is safe and effective in this type of cancer. Participants will receive 5 injections of OBP-301, approximately every 2 weeks. OBP-301 will be injected directly into the tumor during an esophagogastroduodenoscopy (EGD). At the same time as the injection, a tumor biopsy will be taken. Participants will also receive pembrolizumab infusions every 6 weeks until disease progression or for a maximum of two years. Pembrolizumab infusions will occur on different days than OBP-301 injections.
