Three additional iCCA patients (FGFR2 translocations: ROCK1; KIAA1217; DDX21) and one GBC patient (FGFR3-TACC3 translocation) had target lesions regression < 30% and stayed on treatment between 24 – 37 weeks...These results suggest that BTC patients with genomic events, translocations and mutations leading to activation of FGFR2/3, may benefit from treatment with Debio 1347.
