nimotuzumab plus ag in pancreatic cancer with liver metastasis

Conditions: Pancreatic Cancer

Summary: this is a prospective, open-label, single arm clinical study. the main purpose of the study is to evaluate the clinical efficacy and safety of nimotuzumab combined with ag in the treatment of pancreatic cancer with liver metastasis. patients will receive nimotuzumab plus ag as conversion therapy, and imaging assessments (according to recist v.1.1 criteria) will be performed every two cycles (every two months) of conversion therapy. the main endpoint is r0 resection rate. additional end points included resection rates, overall survival (os), objective response rate (orr), safety, etc.

this clinical study is designed as a prospective, open-label, single arm study to evaluate the clinical efficacy and safety of nimotuzumab combined with ag (gemcitabine and nab-paclitaxel) in the treatment of pancreatic cancer with liver metastasis. patients will receive nimotuzumab plus ag as conversion therapy, and imaging assessments (according to recist v.1.1 criteria) will be performed every two cycles (every two months) of conversion therapy. the resectability of the primary pancreatic lesion and liver metastases will be judged based on nccn guidelines and will be determined by a multidisciplinary team of experts. the main endpoint is r0 resection rate. additional end points included resection rates, overall survival (os), objective response rate (orr), safety, etc.
