New imaging agent could light up Hard-to-See cancers
NCT ID NCT07117214
First seen Jun 25, 2026 · Last updated Aug 28, 2026 · Updated 5 times
Summary
This early-phase study tests a new radioactive imaging agent called [68Ga]Ga-DWJ155 in 36 adults with advanced breast cancer or non-small cell lung cancer. The agent is designed to bind to a target on cancer cells and show up on PET scans, helping doctors see where the cancer has spread. The main goals are to check how well the imaging works, how the agent spreads in the body, and whether it is safe.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- [68Ga]Ga-DWJ155 (a radioactive imaging agent for PET scans)
- What this could lead to
- If successful, this could lead to a better way to detect and monitor advanced breast cancer and lung cancer using PET imaging, potentially guiding treatment decisions.
- What could go wrong
- This is a very early, first-in-human study with only 36 participants. The imaging agent may not clearly distinguish tumors from normal tissue, or safety issues could arise. It is not a treatment and will not directly improve outcomes.
