HAIC Combined With TQB2450 and Anlotinib in Second-line Treatment of Advanced Hepatocellular Carcinoma

Overall, although there are many options for second-line treatment of liver cancer, the ORR is mostly limited to within 20-30%, with a median PFS of 3-5 months and a median OS of 10-20 months. The overall situation is still unsatisfactory, with low objective tumor response rates and targeted immune resistance being the main reasons affecting treatment efficacy. Increasing local treatment or overcoming resistance is currently a hot research topic. The aim of this study is to explore the effectiveness and safety of HAIC combined with TQB2450 and anlotinib for second-line treatment of advanced HCC patients.

* Any acute, clinically significant treatment-related toxicity (caused by previous treatment) must have been alleviated to ≤ 1 level before enrollment in the study, except for hair loss
* Patients with active hepatitis B virus (HBV) infection: HBV DNA\<2000IU/mL obtained within 28 days before starting the study treatment, and received at least 7 days of anti HBV treatment (according to local standard treatment, such as entecavir) before joining the study, and were willing to continue to receive treatment during the study period; Patients with active hepatitis C virus (HCV) infection: HCVRNA\<2000IU/mL obtained within 28 days prior to the start of study treatment, and who have received at least 7 days of anti HCV treatment before enrollment in the study and are willing to continue treatment during the study period

Exclusion Criteria:

* Previously received treatment with mitoxantrone;
* History of soft meningitis;
* Current or past autoimmune diseases or immunodeficiencies;
* Idiopathic pulmonary fibrosis, organizing pneumonia (such as bronchiolitis obliterans), drug-induced pneumonia or idiopathic pneumonia, or evidence of active pneumonia can be seen on screening chest computed tomography (CT) images. Allow radiation zone (fibrosis) to have radiation induced pneumonia;
