NCT ID NCT07076550

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

Summary

This early-stage trial tests a radioactive drug called [225Ac]Ac-A9-3408 in 50 adults with melanoma that has spread or can't be removed by surgery. The main goals are to find a safe dose and check for side effects. Participants receive the drug every 6 weeks for up to 6 doses, and doctors will also see if tumors shrink.

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 drug called [225Ac]Ac-A9-3408 given by IV

What this could lead to

If it works, this could point toward a new treatment option for advanced melanoma that has spread or cannot be removed by surgery.

What could go wrong

This is an early Phase 1 trial with only 50 people, so safety and effectiveness are not yet known. The drug is radioactive and may cause side effects; it is not a cure.
