NCT ID NCT05733611

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a new approach using a virus that attacks cancer cells (oncolytic immunotherapy) along with two standard drugs (atezolizumab and bevacizumab) in people with advanced colorectal cancer that had stopped responding to other treatments. The trial was stopped early after enrolling only 5 participants. The goal was to see if the combination could shrink tumors, but results are limited due to early termination.
