This study is a multicenter, single-arm, phase II exploratory study, aims to evaluate the efficacy and safety of metronomic capecitabine with camrelizumab and apatinib mesylate in advanced pancreatic cancer after the failure of first-line treatment.
1: Age is 18 years or older; 2: Pathologically confirmed pancreatic adenocarcinoma; 3: As determined by the investigator, second-line treatment for advanced pancreatic cancer has failed; or the patient has a poor performance status (PS score >1), and the investigator considers that the patient cannot tolerate a second-line regimen with two or more drugs.
1: Patients who have developed resistance after treatment with capecitabine and apatinib are not recommended for enrollment unless more than 6 months have passed since the last dose, in which case they can continue to challenge its use; patients who have previously undergone immunotherapy (regardless of whether or not they used camrelizumab) can cross-line use or switch to camrelizumab to continue challenging its use.
