Most patients present with unresectable disease, and even after curative-intent resection, recurrence is common. Since the ABC-02 trial, gemcitabine plus cisplatin (Gem/Cis) has been established as the standard first-line regimen, but the median overall survival (OS) remains approximately 11.7 months. Recent studies combining immune checkpoint inhibitors (ICIs) such as durvalumab or pembrolizumab with Gem/Cis have improved OS to 12.7-12.9 months, establishing ICI-based combination therapy as the new standard. However, the optimal maintenance therapy following initial chemoimmunotherapy remains undefined.\n\nThis phase IIb study enrolls patients with advanced BTC who achieved disease control after at least eight cycles of Gem/Cis plus ICI. The trial compares the efficacy and safety of ICI monotherapy maintenance versus ICI in combination with lenvatinib, venadaparib, or interleukin-2 (IL-2, SLC-3010).\n\nLenvatinib, through inhibition of FGFR2 and modulation of the tumor immune microenvironment, is expected to enhance ICI efficacy. PARP inhibitors may be beneficial in patients with homologous recombination deficiency (HRD) or platinum-sensitive disease. Additionally, IL-2 can activate tumor-infiltrating lymphocytes and alleviate the immunosuppressive microenvironment, potentially augmenting ICI responsiveness.\n\nThis study aims to explore a novel maintenance strategy integrating molecular targeted therapy, DNA damage repair modulation, and cytokine-based immunotherapy to overcome the limitations of current ICI monotherapy in BTC. The combination approach is expected to improve disease control and survival outcomes in patients with advanced BTC.', 'detailedDescription': 'This phase IIb randomized trial assesses the efficacy and safety of immune checkpoint inhibitor (ICI) monotherapy versus ICI-based combination maintenance therapy with lenvatinib, venadaparib, or SLC-3010 in advanced biliary tract cancer. Durvalumab (q4w) or pembrolizumab (q3w) serve as backbone ICIs. For each group, Lenvatinib is given orally once daily, venadaparib orally, or SLC-3010 as a 60-minute IV infusion. Recommended phase II doses will be established via a 3+3 dose-escalation design, with toxicity management per NCI-CTCAE v5.0.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '19 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n-Patients with advanced biliary tract cancer who have completed at least 8 cycles of Durvalumab plus Gemcitabine and Cisplatin treatment without radiologic evidence of disease progression, and are planned to receive Durvalumab maintenance therapy.\n\n(Patients treated with Pembrolizumab plus Gemcitabine/Cisplatin are also eligible if they are to continue Pembrolizumab monotherapy without Gemcitabine as maintenance therapy.)\n\n* Patients who are 20 years of age or older at the time of signing the informed consent form.\n* Patients with histologically confirmed biliary tract cancer, including intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, or gallbladder carcinoma.\n\n(Patients with neuroendocrine tumors or sarcomas are excluded.)\n\n* Patients who are willing and able to provide written informed consent for participation in the study.\n* Patients with measurable disease according to RECIST version 1.1.\n* ECOG performance status of 0 or 1.\n* Estimated life expectancy ≥ 3 months.\n* Patients with adequate organ and bone marrow function, without transfusion or administration of hematopoietic growth factors (e.g., G-CSF) within 2 weeks prior to treatment initiation, defined as follows:\n* Hemoglobin ≥ 9.0 g/dL\n* Absolute neutrophil count (ANC) ≥ 1.5 × 10⁹/L\n* Platelet count ≥ 75 × 10⁹/L\n* Serum creatinine ≤ 1.5 × upper limit of normal (ULN), or estimated creatinine clearance ≥ 45 mL/min (calculated using the Cockcroft-Gault formula; see Appendix 7)\n* AST and ALT ≤ 3.0 × ULN (≤ 5.0 × ULN if liver metastases are present)\n* Total bilirubin ≤ 2.0 × ULN (≤ 3.0 × ULN for patients with Gilbert's syndrome)\n* International normalized ratio (INR) ≤ 1.5 or prothrombin time ≤ 1.5 × ULN\n* Activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN\n* Women of childbearing potential must agree to use highly effective contraception during the entire study period and for at least 6 months after the last dose of investigational product, and must have a negative serum pregnancy test within 14 days prior to first dose.\n* Male patients who have not undergone sterilization must agree to use highly effective contraception during the entire study period and for at least 120 days after the last dose of investigational product.\n* Patients who are willing to provide tumor tissue samples obtained by endoscopic biopsy or excisional biopsy.\n* Patients who are able to understand and comply with the study procedures and are considered likely to complete the study by the investigator.\n\nExclusion Criteria:\n\n1.
