AI-Summary

What this Trial Is About

This study is conducted in two phases. The phase 1 portion of the study evaluates the safety, tolerability, pharmacokinetics (PK), recommended phase 2 dose (RP2D), and effectiveness of lurbinectedin monotherapy in pediatric participants with previously treated solid tumors. This is followed by the phase 2 portion, to further assess the effectiveness and safety in pediatric and young adult participants with recurrent/refractory Ewing sarcoma.
