Merck's Keytruda nabs FDA nod in biliary tract cancer, catching up with AstraZeneca's Imfinzi

After AstraZeneca’s Imfinzi last year claimed new territory in the biliary tract cancer space, Merck’s Keytruda has hit the scene with an FDA nod to match its rival.

The approval in locally advanced unresectable or metastatic biliary tract cancer, combined with the chemotherapies gemcitabine and cisplatin, marks Keytruda’s sixth U.S. nod in gastrointestinal cancer, Merck said.
