NCT ID NCT03514407

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

Summary

This early-phase trial tested an experimental drug called INCB059872 in 25 people with Ewing sarcoma that had returned or stopped responding to standard treatments. The goal was to check the drug's safety and see if it could shrink tumors. The study was terminated early, so full results are not available.

What this could mean

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

Active substance
INCB059872 (an experimental drug taken by mouth every other day)
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 1) trial with only 25 participants, and it was terminated early, so results are limited. The drug may not shrink tumors or may cause side effects.
