Anlotinib combined with penpulimab and hepatic artery infusion chemotherapy (HAIC) in the first-line treatment of unresectable hepatocellular carcinoma.

Abstract

TPS579 Background: Hepatic arterial infusion chemotherapy (HAIC) is recommended as a treatment option in patients with advanced hepatocellular carcinoma (HCC). Anlotinib plus penpulimab, a humanized anti-PD-1 IgG1 antibody, has shown encouraging activity in the treatment of advanced HCC in an open-label phase II trial (NCT 04172571). Considering different anti-malignancy mechanisms, combining systemic and locoregional therapies may show a potential synergic effect and promising preliminary efficacy results in advanced HCC. Consequently, the aim of this study is to assess the efficacy and safety of Anlotinib, Penpulimab, plus HAIC for advanced HCC. Methods: Trial design: This single-arm, prospective, phase II study will include treatment-naive adult (≥18 years) patients with advanced HCC, ECOG PS 0-2, and Child-Pugh class A-B. A total number of 26 patients will be enrolled for treatment until disease progression or intolerable toxicity. Patients will receive anlotinib(10 mg, p.o., qd, d1-14, q3w), penpulimab (200 mg, i.v., d1, q3w) and HAIC (d1- d2) with the FOLFOX regimen (oxaliplatin 85-130 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 48 hours) for 4-6 cycles, followed by maintenance therapy with anlotinib and penpulimab for up to 2 years. The primary endpoint is objective response rate (ORR)), evaluated using RECIST 1.1. Secondary endpoints are median PFS and overall survival (OS), disease control rate (DCR) per RECIST 1.1, quality of life (QOL) and safety. Recruitment for this study will complete in December 2024.
