Summary

This study tests whether adding the drug abemaciclib to standard chemotherapy can help people with Ewing's sarcoma whose cancer has returned or not responded to treatment. About 46 children and young adults will take part. The goal is to see if the combination slows tumor growth better than chemotherapy alone.
