Summary

This Phase I trial is testing an experimental imaging drug, 203Pb-RMX-VH-PIB, to see how it spreads through the body and how much radiation reaches different organs. The study includes adults with glioblastoma (a type of brain cancer) or pancreatic cancer. Participants receive a single injection of the radioactive tracer followed by multiple SPECT/CT scans to map its distribution and measure radiation exposure.

What this could mean

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

Active substance: a radioactive imaging drug called 203Pb-RMX-VH-PIB
What this could lead to: If successful, this imaging approach could help doctors see tumors more clearly and plan better treatments for brain and pancreatic cancers.
What could go wrong: This is a very early, small Phase I trial with only 20 participants, so it is not designed to prove effectiveness. The radioactive tracer may not distribute as expected or could cause unexpected side effects.
