A Prospective, Randomized, Double-blinded, Multi-center Clinical Trial to Evaluate the Efficiency and Safety of Anti-PD1 Antibody (Camrelizumab) Combined With Paclitaxel(Albumin Bound) and Gemcitabine as First-line Therapy in Patients With Metastatic Pancreatic Cancer

CPOG1210-07 is a prospective, randomized, double-blinded, multi-center clinical trial in China aiming to evaluate the efficiency and safety of anti-PD1 antibody (Camrelizumab) combined with Paclitaxel(Albumin Bound) and Gemcitabine versus Paclitaxel(Albumin Bound) and Gemcitabine as first-line therapy in patients with metastatic pancreatic cancer. The anti-PD1 antibody(Camrelizumab) is a humanized monoclonal antibody which can specifically bind to PD-1 and block the interaction between PD-1 and its ligand (PD-L1), allowing T cells to recover the immune response against tumors. It is proved to be effective in certain cancers such as ovarian cancers and certification proved by Chinese Food and Drug Administration(CFDA) includes Hodgkin's lymphoma, non-small cell lung cancer, esophageal cancer and liver cancer.

Based on Response Evaluation Criteria In Solid Tumors (RECIST1.1), there should be at least one measurable lesion which has never received local treatment like radiotherapy(The lesion located in previous radiotherapy areas can also be selected as target lesions if the progress confirmed.) 5. ECOG:0-1; 6. Expected survival\>=12 weeks; 7. Essential organs function must meet the following criteria (Any blood products, growth factor, leucocyte promoting drugs, platelet promoting drugs, drugs for anemia are not allowed in 14 days before the first use of the experimental medication):
1. Absolute neutrophil count(ANC) \>= 1.5x10\^9/L
2. Platelet \>= 85x10\^9/L
3. Hemoglobin \>= 90g/L
4. Serum Albumin \>= 30g/L
5. Total bilirubin \<= 2.0 ULN (Biliary obstructive patients after biliary drainage \<= 2.5 ULN), AST and ALT \<= 3.0 ULN (patients with liver metastasis \<= 5 ULN);
6. Creatinine clearance rate \>60 mL/min;
7. Activated Partial Thromboplastin Time and International Standardized Ratio \<= 1.5 ULN (Patients using stable dose of anticoagulant therapy such as low molecular weight heparin or warfarin and INR is within the expected range of anticoagulants can be selected.)

You may not be if
