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

Summary

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.

Lay summary

The objective of the study was to assess the benefit of fruqintinib, a chemotherapy drug for patients with metastatic colorectal cancer (mCRC) who do not respond well to previous chemotherapy. The study considered both the time of survival and the quality of life after patients received fruqintinib. In measuring patients’ quality of life, the study assessed the time that was free from cancer symptoms and any severe side effects from treatment. The study used data obtained from a Phase III clinical trial, FRESCO, which included 416 mCRC patients receiving fruqintinib or placebo. The results showed that fruqintinib significantly extended patients’ symptom-free and side effects-free survival time by approximately 2 months and 5 days. Fruqintinib was 16.7–39.9% more effective than placebo in extending mCRC patients’ high-quality life, regardless of prior targeted therapy.
