How would you approach a patient with metastatic squamous NSCLC that progressed on carbo/paclitaxel/pembro and has a FGFR3 S249C mutation?  

Especially if you don't have trials available at the moment.

Would you try off-label erdafitinib (given recent data on bladder cancer) or 2nd line gemcitabine monotherapy?
