Summary

This trial tests a combination of a virus (OBP-301) that kills cancer cells and a drug (pembrolizumab) that helps the immune system fight cancer. It targets patients with advanced stomach and esophagus cancer who haven't responded to other treatments. Pembrolizumab has demonstrated activity in previously treated patients with various cancers, including gastric and esophageal cancers.

Experimental Treatment
Group I: Telomelysin (OBP-301)Experimental Treatment1 Intervention
All patients will receive Telomelysin (OBP-301) at 2x10\^12 viral particles (VP)/ tumor injection administered every two weeks x 4 injections as well as standard dose pembrolizumab 200 mg IV every 3 weeks. The tumor will be injected with OBP-301 four times (d1, d15, d29, d43). The preference is to inject the primary tumor endoscopically. Metastatic lesions may be injected on a case-by-case basis after discussion with the PI (Shah).
