Summary

This phase 1 trial is testing an experimental therapeutic cancer vaccine called AST-021p in people with advanced solid tumors that no longer respond to standard treatments. The goal is to see if the vaccine is safe and can trigger an immune response against the cancer. Participants receive a series of injections at different dose levels to find the best and safest dose.
