Brief Summary

This trial is a multi-center, randomized, open, parallel-group and positive-controlled phase III trial to evaluate the efficacy and safety of paclitaxel polymeric micelles for injection plus gemcitabine as first-line treatment of metastatic pancreatic cancer compared with nab-Paclitaxel plus gemcitabine.

Detailed Description
