Subgroup analyses favored PFS with fruquintinib, as it was significantly longer vs. placebo for all patient subsets except for those with brain metastases. The median overall survival also was numerically greater with fruquintinib among patients positive for EGFR mutations (8.4 vs. 5.5 months; HR, 0.58; 95% CI, 0.30-1.141 P =.11).
Treatment emergent adverse events were higher in the fruquintinib arm (100% vs. 90%), but most of these were grade 1/2 in both groups. The most common grade 3 and higher events observed with fruquintinib were hypertension (8.2%), hand-foot syndrome (4.9%), and proteinuria (4.9%).
