LiquidMARK™ Bile Duct, powered by AmpliMARK™ next generation sequencing technology, is an ultrasensitive next-generation sequencing blood test that identifies relevant gene mutations – including the fibroblast growth factor receptor 2 (FGFR2) fusion gene that Innovent’s Pemazyre® is effective against. Patients with FGFR2 fusion identified through the LiquidMARK™ Bile Duct test will be eligible to receive Pemazyre® as second-line treatment.
