Official title
Precision Analysis of Fusion Genes in Ewing Sarcoma (ES) and Desmoplastic Small Round Cell Tumor (DSRCT), Then EWSR1 Immunotherapy Without or With Anti-PD1 (Pembrolizumab)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is for people who have high-risk Ewing sarcoma (ES), or a related Ewing's family tumor, desmoplastic small round cell tumor (DSRCT). The purpose of this study is to see if a new EWSR1 immunotherapy (a lipid nanoparticle coated with EWSR1 mRNA) which is given as a shot is safe and whether it can help the body's immune system better recognize and fight cancer. This EWSR1 immunotherapy is designed to target a specific genetic change (EWSR1 fusion gene) that is found in cancer cells but not in normal, healthy cells. Because the EWSR1 gene is broken in cancer cells and the small protein it makes are only in the ES or DSRCT cancer cells, the goal of EWSR1 immunotherapy is to help the immune system identify and attack the cancer without harming normal cells. It is not yet approved by the Food and Drug Administration (FDA). EWSR1 immunotherapy will be given as a shot into the muscle of the arm, leg, or buttock. If participants also receive pembrolizumab (an infusion every 2 weeks), it is given intravenously (IV) by a needle in the arm over 30 minutes. Participants in this study will receive treatment for about 6 months or until their cancer gets worse. Participants will remain in the study for follow-up for an additional year, for a total time of about 1.5 years in the study.
