New PET tracer aims to reveal which cancers will respond to immunotherapy

NCT ID NCT07140315

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests a new radioactive imaging agent, [18F]DK222, in 6 people with non-small cell lung cancer or urothelial cancer. The agent is designed to attach to PD-L1, a protein that helps cancer hide from the immune system. Researchers want to see if the agent is safe, how it moves through the body, and how much radiation it gives off. This is not a treatment—it is a way to potentially improve cancer imaging.

What this could mean

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

Active substance

[18F]DK222 radiotracer

What this could lead to

If successful, this could lead to a better way to see which cancers might respond to immunotherapy, helping doctors choose the right treatment.

What could go wrong

This is a very early, small study with only 6 people. The imaging agent may not work as hoped, or safety issues could arise. It is not a treatment.
