Efficacy and Safety Study of PDT Using Deuteporfin for Unresectable Advanced Perihilar Cholangiocarcinoma

This is a multi-center, randomized, controlled, open-label, phase IIa clinical study.The study will observe the efficacy and safety of Deuteporfin photodynamic therapy in addition to stenting compared to stenting alone in patients with unresectable advanced Perihilar Cholangiocarcinoma.
