Human tumour xenografts in mice with FGFR1-3 activation, incl. patient-derived FGFR2-TRA2B cholangiocarcinoma xenografts
“Pemigatinib exhibited in vivo anti-tumor activity in mice bearing subcutaneous (SC) human xenografts with FGFR1, FGFR2, or FGFR3 activation, including patient-derived cholangiocarcinoma xenografts expressing a FGFR2 TRA2B fusion and FGFR2-amplified human gastric cancer xenografts.”

Reviewer's view of the efficacy data
EMA: in vivo antitumour activity shown across FGFR1-3-altered human tumour models, including patient-derived xenografts
“In vivo, pemigatinib demonstrated antitumour activity in rodents bearing tumours derived from multiple human cancer cell lines with FGFR1, 2, and 3 alterations (translocation or amplification) including gastric, cholangiocarcinoma, bladder, and in a mouse study using patient-derived xenografts originated from blood expressing FGFR1 fusion protein.”
