Alternating HAIC and Systemic Chemotherapy With or Without Adebrelimab and Apatinib for Unresectable Biliary Tract Cancer

29. April 2026 aktualisiert von: Tie Jun, Air Force Military Medical University, China

A Prospective, Real-World Study of Alternating Hepatic Arterial Infusion Chemotherapy and Systemic Chemotherapy With or Without Adebrelimab and Apatinib in Patients With Unresectable Biliary Tract Cancer

This prospective real-world study aims to evaluate the effectiveness and safety of an alternating treatment regimen combining hepatic arterial infusion chemotherapy (HAIC) with systemic chemotherapy, with or without adebrelimab and apatinib, in patients with unresectable biliary tract cancer receiving first-line treatment. The study comprises two cohorts: one receiving alternating HAIC and systemic chemotherapy alongside adebrelimab and apatinib, and the other receiving alternating HAIC and systemic chemotherapy alone. Treatment allocation follows real-world clinical decision-making. Patients will be monitored throughout the treatment period to assess tumor response, survival outcomes, and safety profiles. The study aims to generate evidence on the clinical benefits of integrating immunotherapy and targeted therapy into HAIC-based regimens for this patient population.

Detaillierte Beschreibung

Biliary tract cancer (BTC), which includes intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder cancer, is an aggressive malignancy associated with a generally poor prognosis. For patients with unresectable, locally advanced, or metastatic disease, first-line systemic chemotherapy using gemcitabine and cisplatin remains the standard of care, although treatment outcomes are ofter suboptimal. HAIC has gained increasing attention in clinical practice, paticularly in China, for its ability to enhance local drug delivery and improve tumor control in cases of liver-dominant disease. Alternating HAIC with systemic chemotherapy may provide additive benefits by simultaneously targeting both intrahepatic and extrahepatic lesions.

Recent advances in immunotherapy and anti-angiogenic therapy have shown promise results in BTC. Adebrelimab, a PD-L1 inhibitor, and apatinib, a VEGFR2 inhibitor, have demonstrated antitumor activity in various solid tumors. Combining these agents with chemotherapy and HAIC may yield synergistic effects, potentially improving response rates and extending survival.

This prospective real-world study is designed to evaluate the effectiveness and safety of an alternating regimen of HAIC and systemic chemotherapy (gemcitabine plus cisplatin), with or without adebrelimab and apatinib, in patients with previously untreated, unresectable, locally advanced or metastatic BTC. Participants will be assigned to one of two cohorts based on patient preference and clinician judgment: Cohort A will receive HAIC and systemic chemotherapy combined with adebrelimab and apatinib, while Cohort B will receive HAIC and systemic chemotherapy alone. Dosing and administration will follow the standard treatment protocols.

The study will capture real-world data on objective tumor response, progression-free survival, overall survival, and safety profiles. Exploratory analyses may include patterns of disease progression, treatment adherence, and the influence of clinical and biological factors on outcomes. The results are anticipated to offer valuable evidence to guide clinical decision-making and help optimize first-line treatment strategies for patients with advanced BTC in routine practice.
