NCT ID NCT05581004

First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 4 times

Summary

This early-phase trial is testing a new drug called enzelkitug, alone or with standard immunotherapies, in people with advanced solid tumors that have not responded to other treatments. The main goals are to check safety, find the right dose, and see if the drug shrinks tumors. About 450 participants with various cancers like lung, melanoma, and breast cancer are being enrolled.

What this could mean

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

Active substance
enzelkitug (a drug, also called RO7502175), given alone or with atezolizumab or pembrolizumab
What this could lead to
If it works, this could point toward a new treatment option for several advanced cancers that are hard to treat.
What could go wrong
This is a very early (first-in-human) trial, so safety and the right dose are still unknown. Many early cancer drugs do not end up working in larger studies.
