Regorafenib in patients with metastatic colorectal cancer in Spain: from clinical trials to real-world evidence.

Aim: To describe the evolution of regorafenib use, since its approval, in patients with previously treated metastatic colorectal cancer (mCRC) in routine clinical practice in Spain. Methods: We extracted patient characteristics, dosing, safety and efficacy data for the Spanish cohorts of the CORRECT and CONSIGN trials, and the real-world CORRELATE study. Results: The Spanish cohorts represented 10.7-13.8% of the global cohorts. Efficacy and safety in the Spanish cohorts reflected findings from the global cohorts, with evidence of a flexible dosing approach being adopted in routine clinical practice. Conclusion: Regorafenib use in patients with mCRC has evolved in the real-world setting, emphasizing the need for further research evaluating dosing patterns that can optimize clinical outcomes in these patients.Clinical trial registration: The CORRECT trial is registered at ClinicalTrials.gov, number NCT01103323; the CONSIGN trial is registered at ClinicalTrials.gov, number NCT01538680; the CORRELATE study is registered at ClinicalTrials.gov, number NCT02042144.
