It is the most common soft tissue sarcoma seen in children. RMS cancer cells have a protein called FGFR4 on their surface. Researchers want to try a new kind of treatment for RMS: They will collect a person s own T cells, a type of immune cell; then they will change the T cells so they are better able to target the FGFR4 protein and attack RMS tumor cells. The modified T cells are chimeric antigen receptor (CAR) T cells. The treatment in this study is called FGFR4-CAR T cells.\n\nObjective:\n\nTo test FGFR4-CAR T cells in children and young adults with RMS.\n\nEligibility:\n\nPeople aged 3 to 39 years with RMS. The RMS must have failed to respond or returned after at least 2 rounds of standard treatment.\n\nDesign:\n\nParticipants will be screened. They will have physical exam, imaging scans, blood tests, and tests of their heart. They may have a tissue sample taken from their tumor.\n\nThey will undergo apheresis: Blood will be taken from the body through a catheter. The blood will pass through a machine that separates out the T cells, and the remaining blood will be returned to the body. The collected T cells will be taken to a lab to create FGFR4-CAR T cells.\n\nOnce the FGFR4-CART cells are ready, participants can receive these T cells. For 4 days they will receive drugs to prepare their body for the FGFR4-CAR T cells. After this, the modified T cells will be infused into a vein.\n\nParticipants will be then monitored closely to watch for any side effects from the CART cells and be followed to see what effect the CART cells have on their tumors. They will have follow-up visits for up to 5 years. Long-term follow-up will be another 10 years.",[97],"Rhabdomyosarcoma",[99,100,101,97,102],"Sarcoma","Solid Tumor","CAR T Cells","FGFR4","2026-03-13",{"date":105,"type":106},"2026-03-16","ACTUAL",{"date":108,"type":106},"2025-09-22",{"date":110,"type":91},"2029-04-01",{"name":44,"class":6},1]
