Data are n (%) unless otherwise stated. FGFR=fibroblast growth factor receptor. ECOG=Eastern Cooperative Oncology Group.
The total includes one patient who did not have confirmed FGFftGFR status by central laboratory and was not assigned to any cohort.
Rest of world consists of Israel, South Korea, Taiwan, Thailand, and Japan.
Maximum number of five therapies in patients with FGFR2 fusions or rearrangements and three in the other patient cohorts.
Cholangiocarcinoma location was initially missing for one patient at the data cutoff date; however, this patient was later assessed as having intrahepatic cholangiocarcinoma after the data cutoff date.
The other locations were the gallbladder (n=2) and ampulla of Vater (n=1).
