New drug xaluritamig takes on tough ewing sarcoma in early trial

NCT ID NCT07297979

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

Summary

This early-phase trial is testing a drug called xaluritamig (AMG 509) in 50 adults, adolescents, and children with Ewing sarcoma that has relapsed or not responded to prior treatments. The main goals are to find a safe dose and check for side effects. Researchers will also measure how the drug moves through the body and look for any signs that it is fighting the cancer.

What this could mean

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

Active substance

xaluritamig (AMG 509), a drug given by IV infusion

What this could lead to

If it works, this could point toward a new treatment option for people with Ewing sarcoma that has come back or not responded to standard therapy.

What could go wrong

This is a very early (phase 1b) and small trial (50 people), so it may not show enough benefit or could have side effects. Success is far from guaranteed.
