Summary

This early-phase trial tests a cancer vaccine (Pseudovax) plus an immunotherapy drug (tislelizumab) in 10 adults with pseudomyxoma peritonei, a rare abdominal cancer that has returned or cannot be surgically removed. The vaccine targets tumors with a specific GNAS gene mutation, and the immunotherapy helps the immune system attack cancer cells. The main goals are to check safety and measure immune responses.
