Hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, leucovorin, and 5-fluorouracil (FOLFOX) is effective in patients with unresectable ICC. In this study, we determined the preliminary clinical efficacy and safety of lenvatinib plus durvalumab combined with FOLFOX-HAIC in patients with untreated, unresectable ICC.&lt;h4>Materials and methods&lt;/h4>Between July 2021 and July 2023, patients with unresectable ICC who initially received lenvatinib plus durvalumab combined with FOLFOX-HAIC at the Sun Yat-Sen University Cancer Center (SYSUCC) were reviewed for eligibility. Efficacy was evaluated by tumor response rate and survival, and safety was assessed by the frequency of key adverse events (AEs).&lt;h4>Results&lt;/h4>A total of 28 eligible patients were enrolled. The objective response rates (ORRs) based on mRECIST and RECIST 1.1 criteria were 65.2% and 39.1%, respectively. The median OS was 17.9 months (95% CI, 5.7-30.1) and the median PFS was 11.9 months (95% CI, 6.7-17.1). Most patients (92.9%) experienced adverse events (AEs), whereas 46.5% (13/28) experienced grade 3 or 4 AEs.&lt;h4>Conclusion&lt;/h4>Lenvatinib plus durvalumab combined with FOLFOX-HAIC showed promising antitumor activity and manageable AEs in patients with treatment-naive unresectable ICC. This regimen may be suitable as a novel first-line treatment option for this patient population.</pubmed_abstract><journal>Frontiers in immunology</journal><pagination>1397827</pagination><full_dataset_link>https://www.ebi.ac.uk/biostudies/studies/S-EPMC11116590</full_dataset_link><repository>biostudies-literature</repository><pubmed_title>Efficacy and safety of lenvatinib plus durvalumab combined with hepatic arterial infusion chemotherapy for unresectable intrahepatic cholangiocarcinoma.</pubmed_title><pmcid>PMC11116590</pmcid><pubmed_authors>Li S</pubmed_authors><pubmed_authors>Zhao R</pubmed_authors><pubmed_authors>Wei W</pubmed_authors><pubmed_authors>Guo R</pubmed_authors><pubmed_authors>Miao Z</pubmed_authors><pubmed_authors>Zhou J</pubmed_authors><pubmed_authors>Xiong X</pubmed_authors></additional><is_claimable>false</is_claimable><name>Efficacy and safety of lenvatinib plus durvalumab combined with hepatic arterial infusion chemotherapy for unresectable intrahepatic cholangiocarcinoma.</name><description>&lt;h4>Background&lt;/h4>The prognosis for unresectable intrahepatic cholangiocarcinoma (ICC) is poor and the efficacy of traditional chemotherapy remains unsatisfactory.
