Brief summary: Biliary tract cancer (BTC) presents with a 5-year survival rate less than 5%. The goal of this clinical trial is to evaluate if Anlotinib plus Nab-Paclitaxels and S-1 as second-line regimen can improve the treatment efficacy in advanced biliary tract cancer (BTC) after progression upon first-line standard treatment, in comparison with standard second-line FOLFOX regimen.

Detailed description: Biliary tract cancer (BTC) mainly includes intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma, extrahepatic cholangiocarcinoma and gallbladder carcinoma, and the 5-year survival rate is less than 5%. Most patients were diagnosed as advanced stage, and missed the opportunity of radical surgery. ABC-02 study established gemcitabine combined with platinum drugs as the first-line standard treatment for unresectable BTC. However, after the disease progresses, the second-line treatment options and efficacies are limited. In recent years, BTC second-line treatment has made some breakthroughs in the field of chemotherapy and targeted therapy. However, the benefits of chemotherapy, immunotherapy and targeted drugs alone in the second line treatment of BTC is unsatisfactory. The combined scheme of two or three drugs sees the possibility of patients benefiting, but it still needs better scheme design and larger sample size for further verification. A phase II single-arm small-sample clinical trial exploring albumin-bound paclitaxel combined with S-1 capsule in the first-line treatment of advanced biliary adenocarcinoma initially showed the efficacy and safety of AS regimen in cholangiocarcinoma, and the efficacy and safety of Anlotinib in BTC were also confirmed in the small-sample study. Therefore, this study intends to explore the efficacy and safety of the second-line treatment of advanced BTC with Anlotinib combined with AS chemotherapy in comparison with the establised standard second-line regimen (FOLFOX).

12. Subjects with a history or current evidence of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonitis, or severely impaired lung function;
13. Subjects with a history or current evidence of bronchiectasis, cavitary pulmonary tuberculosis, lung abscess, rheumatic heart disease with mitral valve stenosis, or cardiogenic pulmonary edema, which could cause hemoptysis;
14. Subjects with congenital or acquired immune deficiencies, such as those infected with HIV or with active hepatitis (transaminase levels not meeting inclusion criteria, hepatitis B reference: HBV DNA ≥1000 IU/ml; hepatitis C reference: HCV RNA ≥1000 IU/ml);

16. Subjects with a known history of psychiatric drug abuse, alcoholism, or drug addiction;
17. Pregnant or breastfeeding women or those planning to conceive during the study period;
18. Subjects whom the investigator deems should be excluded from the study, such as those with factors that may lead to early termination of the study.
