Regorafenib Assessment in Refractory Advanced Colorectal Cancer(RegARd-C)

• Status: Completed
• Trial end date: 2019-06-17
• Target enrollment: 0
• Participant gender: All

Summary

The general objectives are to evaluate activity and the safety of regorafenib in a population of patients bearing advanced, refractory colorectal cancers and to explore the different downstream molecular pathways to identify tumor response and resistance mechanisms.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
