Lenvatinib targets VEGFR1, 2, and 3, PDGFRα, Fibroblast growth factor receptor (FGFR), and the KIT and RET tyrosine kinases and was initially developed for use in various tumor types. This is a single-center, non-random, open-label study in participants with unresectable BTC and disease progression or failure following at least one chemotherapy regimen. This study contains three procedures: a pre-treatment procedure that will last within 21 days; a treatment procedure that will consist of study treatment cycles and tumor assessment conducted every 6-8 weeks; and a follow-up procedure that will begin immediately after the off-treatment visit and will continue as long as the participant is alive, unless the participant withdraws consent, or until the terminal of the study.
