Current therapeutic options for advanced synovial sarcomas remain limited. Adoptive T-cell therapies against NY-ESO-1 and MAGE-4 benefit a subset of patients, but is of limited value in Asian patients due to the absence of the HLA-A*02 genotype. Methods: The trial had a single arm, Simon two-stage design that included patients with advanced synovial sarcomas who had progressed on 2 lines of therapy, one of which could be an anti-VEGF therapy. Regorafenib was administered orally in a continuous regimen with 80mg and 120 mg doses on alternate days. The primary end point was 3-month progression-free rate (PFR). A 3-month PFR of greater than 40% was taken to be a marker of drug efficacy. Secondary end points included median PFS, OS and safety analysis. Quality of life assessment was carried out at baseline and at 3 months using the EORTC C-30 questionnaire. Radiological responses were assessed using RECIST 1.1 criteria after independent review by 2 radiologists.
