89 patients received EV on completed monotherapy...Compared to FGFR3- pts, FGFR3+ pts with no prior FGFRi had significantly shorter median PFS on EV (2.5 vs. 6.8 months; HR 0.33 [0.14 – 0.80] p < .01) and trend towards shorter median OS (4.9 vs. 14.6 months; HR 0.42 [0.16 – 1.08] p > .05)...In this retrospective study, FGFR+ patients who receive EV first appear to have shorter PFS and lower ORR than those who have received prior FGFRi.
