What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 174 participants in total. It began in 2024-07-19 with a primary completion date of 2027-09.

Brief Summary

The main objective is to evaluate the impact of a Regorafenib combined with metronomic chemotherapy (capecitabine and cyclophosphamide) and low-dose aspirin compared to standard Regorafenib treatment in patients with metastatic colorectal cancer by assessing progression-free survival.
