Adebrelimab Combined with Irinotecan Liposomes, 5-FU, CF ± Lenvatinib As First-line Treatment for Advanced ICC

This study plans to recruit 68 patients with unresectable ICC who have not received prior systematic treatment. The patients will be randomly divided into two groups. Group A: patients will receive adebrelimab+irinotecan liposomes+5-fluorouracil+calcium folinate+lenvatinib; Group B: patients will receive treatment with adebrelimab+irinotecan liposomes+5-fluorouracil+calcium folinate. The combination of irinotecan liposomes+5-fluorouracil+calcium folinate will be used 9 times (Q2W), and adebrelimab ± lenvatinib will be used until disease progression or medication for 2 years.
