Overview
Brief Summary
The purpose of this study is to measure the benefit of adding abemaciclib to chemotherapy (irinotecan and temozolomide) for Ewing's sarcoma that has come back or did not respond to treatment. This trial is part of the CAMPFIRE master protocol, which is a platform to speed development of new treatments for children and young adults with cancer. Your participation in this trial could last 11 months or longer, depending on how you and your tumor respond.

Outcomes
Primary Outcomes
Progression Free Survival (PFS) Assessed by Blinded Independent Review Committee (BIRC) by Bayesian Analysis
Time Frame: From Date of Randomization until Disease Progression or Death Due to Any Cause (Up to 22.36 months)
PFS was defined as the time from randomization until the first occurrence of documented disease progression per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) criteria, or death from any cause in absence of progressive disease, whichever came first. Progressive disease (PD) was defined as at least 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 millimeter (mm), or unequivocal progression of non-target lesions, or 1 or more new lesions. An event was considered when tumor progression or death occurred, with event date being the earliest date of PD or death. Participants known to be alive and without tumor progression were censored at date of their last adequate tumor assessment per RECIST v1.1 criteria, or date of randomization (whichever was later). Results were obtained using Bayesian analysis and are reported as posterior mean along with its 80% credible interval.
