Efficacy and Safety Comparison of Regorafenib and Fruquintinib in Metastatic Colorectal Cancer-An Observational Cohort Study in the Real World
Abstract
BACKGROUND
Regorafenib and fruquintinib are tyrosine kinase inhibitors that are recommended for refractory colorectal cancer (CRC) in China. However, to date, no head-to-head trials have been conducted to guide clinical practice.
METHODS AND PATIENTS
An ambispective observational cohort study was conducted in Beijing Cancer Hospital. Patients with metastatic CRC who received regorafenib or fruquintinib were retrospectively collected between January 2018 and April 2020, and prospectively enrolled between May 2020 and February 2021. The primary outcome was time-to-treatment failure (TTF), and secondary outcomes were overall survival (OS) and adverse events. An additional goal of the study was to explore the appropriate sequence of regorafenib and fruquintinib treatment.
RESULTS
A total of 366 patients with metastatic CRC were enrolled to receive regorafenib (n = 260) or fruquintinib (n = 106) between January 2018 and February 2021. No difference was observed for median TTF (regorafenib 2.7 months vs. fruquintinib 3.1 months, P = .200) or median OS (regorafenib 13.8 months vs. fruquintinib 11.3 months, P = .527). The propensity score analysis showed similar results for median TTF and median OS between the 2 groups, as did the results of subgroup analysis for prospective set (n = 146). For sequence analysis, patients with regorafenib followed by fruquintinib (n = 84) showed longer OS than that with the reverse (n = 29) (28.1 months vs. 18.4 months, P = .024). Most patients…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 366 participants or records.
