First seen Apr 17, 2026 · Last updated May 13, 2026 · Updated 5 times

Summary

This study tests a genetically modified, weakened bacteria (T3P-Y058-739) in about 100 adults with advanced solid tumors that have no standard treatment options. The bacteria is given alone or with the immunotherapy drug pembrolizumab, either as an injection into the tumor or into a vein. The goal is to find a safe dose and see if it can shrink tumors or slow their growth.
