We report a case of a frail 68-year-old woman with stage 4 pancreatic carcinoma harbouring a fibroblastic growth factor receptor 2 (FGFR2) fusion who achieved a durable complete response after treatment with erdafitinib a pan-FGFR inhibitor. The FGFR2-TACC2 fusion was detected on comprehensive tumour somatic mutation profiling. There is ongoing complete response at 10 months after initiation of erdafitinib. Transient central serous retinopathy, grade 2 hyperphosphataemia and diarrhoea were the adverse events encountered.
