NCT ID NCT07170592

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial tests a new cancer treatment called OTS-412, a modified virus designed to attack tumor cells. It is given alone or with hydroxyurea and the immunotherapy atezolizumab. The study includes 24 adults with advanced solid tumors that no longer respond to standard treatments. The main goal is to check safety and find the best dose.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

OTS-412 (a modified virus that targets cancer cells), hydroxyurea, and atezolizumab

What this could lead to

If successful, this could point toward a new combination treatment option for patients with advanced solid tumors that have stopped responding to standard therapies.

What could go wrong

This is a very early phase 1 trial with only 24 participants, focused mainly on safety and dosing. It is too small to prove effectiveness, and the virus-based therapy may cause side effects or fail to shrink tumors.
