Overview
This is a prospective, single-arm trial. The main purpose of the study is to evaluate the efficacy and safety of Nimotuzumab combined with nab-paclitaxel+ gemcitabine (AG regimen) for postoperative adjuvant treatment of pancreatic cancer with EGFR-positive.
Description
This clinical study is designed as a prospective, open-label, single arm, phase II study to evaluate the clinical efficacy and safety of Nimotuzumab combined with AG (nab-paclitaxel+ gemcitabine) as postoperative adjuvant therapy in patients with EGFR-positive pancreatic cancer. The main endpoint is disease-free survival (DFS). Additional end points included distant metastasis-free survival (DMFS), overall survival (OS), tumor-related markers and safety.
Eligibility
Inclusion Criteria:

- 2\. Age 18-75 years old, gender unlimited;
- 3\. Histologically or cytologically confirmed resected pancreatic ductal adenocarcinoma (PDAC), resectable evaluation is based on criteria of NCCN guidelines, no evidence of distant metastasis as demonstrated by imaging;
- 4\. Postoperative pathology suggested R0/R1 resection;
- 5\. EGFR positive (by immunohistochemistry);
- 6\. KRAS gene and CDX-2 protein status must have been determined at baseline (only for post hoc analysis);

- 8\. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;

- 4\. Postoperative complications such as bleeding, pancreatic fistula, gastric obstruction, abdominal infection, and biliary fistula, which made the patient unable to receive adjuvant therapy within 12 weeks after surgery;
- 5\. CA199\>180 U/ml within 21d before adjuvant therapy;
- 6\. Known allergy to prescription or any component of the prescription used in this study;
