Lurbinectedin in FET-Fused Tumors
brief summary
The purpose of this study is to find out if a drug called lurbinectedin (the "study drug") is safe and effective at treating people with recurrent or relapsed solid tumors, including Ewing sarcoma.
detailed description
In this study, the investigators will test the activity of lurbinectedin as a targeted therapy for FET (FUS, Ewing Sarcoma Breakpoint Region 1 (EWRS1), TATA-Box-Binding Protein Associated Factor 15 (TAF15)). Ewing sarcoma is driven by the Ewing Sarcoma-Friend Leukemia Integration 1 Transcription Factor (EWS-FLI1). Lurbinectedin has been shown to inhibit EWS-FLI1 and Ewing Sarcoma-Wilms' Tumor Gene 1 (EWS-WT1) in preclinical models. Therefore, the goal of this study is to see if Lurbinectedin can be used to inhibit EWS-FLI1, EWS-WT1, or other FET fusion proteins to drive tumor responses in patients.
