About this trial

This is a proof of principle clinical trial determining efficacy of single dose dualimmune checkpoint inhibitors to increase intra-tumoral T cells in esophageal, gastroesophageal junction, and gastric adenocarcinomas. These are subjects who have not previously been treated for their disease, who are willing to undergo biopsy procedures, who's disease has not spread to other parts of the body, who's tumors have ARID1A mutations.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Non metastatic GEC including locally advanced unresectable

Treatment naïve

Histologically proven adenocarcinoma of the esophagus or the stomach with ARID1a mutation either by liquid biopsy (ctDNA) or tissue NGS/WES

MSI-Stable or pMMR

Disqualifiers

Patients with known metastatic disease

Prior systemic treatment for esophagus, GEJ, or the stomach adenocarcinoma

Patients with uncontrolled autoimmune disease per investigator discretion

Inability or refusal to undergo biopsy procedures to obtain tissue samples
