Tislelizumab With Anlotinib and Chemotherapy for Second-line Treatment of Pancreatic Cancer

Study Overview
=================
Brief Summary
-----------------
This is a prospective, one-arm, phase II clinical study of Tislelizumab Combined With Anlotinib and Chemotherapy for Second-line Treatment of Advanced or Metastatic Pancreatic Cancer

Detailed Description
-----------------
This is a single-arm, open-label, clinical trial of tislelizumab in combination with anlotinib and investigator-selected chemotherapy for second-line treatment of patients with advanced or metastatic pancreatic cancer. Patients with histopathologically or cytologically confirmed unresectable, recurrent or metastatic pancreatic cancer are planned to be recruited. Systemic medical antineoplastic therapy previously treated with first-line chemotherapy, meeting the inclusion and exclusion criteria of this study, and giving tislelizumab and anlotinib in combination with investigator 's choice of second-line chemotherapy regimen
