Signed written informed consent obtained prior to any trial-related procedures.
Male or female, ≥18 years and ≤75 years.
Histologically confirmed unresectable advanced or metastatic intrahepatic cholangiocarcinoma (ICC). Patients who developed recurrence more than 6 months after radical surgery are eligible.

History of active autoimmune disease requiring systemic therapy (e.g., disease-modifying agents, corticosteroids, or immunosuppressants) within 2 years prior to the first dose. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement for adrenal or pituitary insufficiency) is not considered systemic therapy.
