New PET scan agent aims to spot HER2 cancers more safely

NCT ID NCT04692831

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

Summary

This phase 1 trial tests whether a new radioactive imaging agent, 89Zr-ss-pertuzumab, is safe for detecting HER2-positive breast cancer in 60 participants. The agent is designed to bind to HER2 proteins on cancer cells and show up on PET/CT scans. The main goal is to check for side effects, not yet to measure how well it works.

What this could mean

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

Active substance

89Zr-ss-pertuzumab (a radioactive imaging agent)

What this could lead to

If successful, this could provide a safer and more precise way to detect HER2-positive cancers using PET/CT scans, helping guide treatment decisions.

What could go wrong

This is an early phase 1 trial focused on safety, not effectiveness. The imaging agent may not work as expected, and results may not apply to all patients.
