{Abstract}: Systemic chemotherapy is the main treatment option for patients with advanced intrahepatic cholangiocarcinoma (iCCA), however, its efficacy is limited. Herein, we report a young patient with NRAS-mutated chemoresistant metastatic iCCA, who received second-line therapy with a combination of trametinib (MEK1/2 inhibitor), hydroxychloroquine (autophagy inhibitor), and bevacizumab (angiogenesis inhibitor). A significant response was achieved during therapy, resulting in a 25% decrease in the size of tumor lesions after 2 months of treatment and an improvement in the patient's condition. The duration of this response was 4 months, but the patient died 10 months after the initiation of this triple therapy. This case report and the analysis of other available studies warrant further investigations on combined MEK and autophagy inhibition in RAS-mutated tumors.
