Quality-adjusted survival in patients with metastatic colorectal cancer treated with fruquintinib in the FRESCO trial

Abstract

Aim: To assess whether the survival benefit of fruquintinib is quality-adjusted. Materials & methods: Data of 416 metastatic colorectal cancer patients from the Phase III FRESCO trial were used. The Quality-adjusted Time Without Symptoms or Toxicity (Q-TWiST) analysis assessed the quality-adjusted survival benefit of fruquintinib versus placebo, accounting for freedom from symptomatic disease and from severe side effects of treatment. Results: Fruquintinib significantly improved patients’ Q-TWiST (difference: 2.23 [1.41, 3.04] months) versus placebo. The Q-TWiST gain was 28.3% in the base case and ranged from 16.7 to 39.9% in the threshold analysis, favoring fruquintinib. The Q-TWiST benefit was observed in fruquintinib-treated patients regardless of prior targeted therapy. Conclusion: Fruquintinib provides a clinically meaningful quality-adjusted survival benefit versus placebo as a third-line treatment for metastatic colorectal cancer patients.
