Conditions:

Gastric Cancer

Eligibility:

All Genders

21-99 years

Phase:

PHASE1

Brief Summary

The primary hypothesis is that cancer vaccine can convert non-immunogenic gastric cancer into immunogenic phenotype susceptible to PD1 inhibition. This would lead to an improved radiological response ...

Detailed Description

Primary Objectives 1. Safety cohorts: To evaluate the safety of OTSGC-A24 and nivolumab (+ ipilimumab) in patients with refractory gastric cancer. 2. Arm A: To determine the objective response rate o...
