Safety and Efficacy of NRT6008 in Patients With Unresectable Locally Advanced Pancreatic Cancer (LAPC)
Status: Not yet recruiting

This is a single arm, open label, multi-center phase I study, including phase Ia dose escalation and phase Ib dose expansion. Safety review committee (SRC) will be formed to monitor safety and efficacy data through the study. And the independent review committee (IRC) will be formed to monitor efficacy data through the study.
