Efficacy and safety of fruquintinib in patients with refractory metastatic colorectal cancer: a FRESCO-2 subgroup analysis of patients enrolled in Japan

Resumo original em inglês

O que aconteceu

In the phase 3 FRESCO-2 study, fruquintinib plus best supportive care (BSC) significantly improved overall survival (OS) versus placebo plus BSC in patients with refractory metastatic colorectal cancer (mCRC). We present the results of a FRESCO-2 post hoc subgroup analysis evaluating outcomes of patients enrolled in Japan.

In FRESCO-2, patients had previously received all standard chemotherapies, anti-VEGF and anti-EGFR therapies if indicated, and had progressed on, or were intolerant to trifluridine-tipiracil and/or regorafenib. Patients were randomized 2:1 to receive fruquintinib 5 mg or matching placebo by mouth once daily on days 1-21 in 28-day cycles, plus BSC. The primary endpoint was OS; secondary endpoints included progression-free survival (PFS) and safety.

O que encontraram

Of the 56 patients enrolled in Japan, 40 (71.4%) and 16 (28.6%) were randomized to fruquintinib and placebo, respectively. OS was improved with fruquintinib versus placebo (median 6.9 vs. 5.6 months; hazard ratio [HR], 0.42; 95% confidence interval [CI] 0.19 - 0.92). PFS was also improved with fruquintinib versus placebo (median 3.6 vs. 1.8 months; HR, 0.27; 95% CI 0.13 - 0.56). The incidence of grade ≥ 3 treatment-emergent adverse events (TEAEs) with fruquintinib versus placebo was 71.8% versus 29.4%; the most common grade ≥ 3 TEAEs with fruquintinib were hypertension (23.1%) and palmar-plantar erythrodysesthesia (17.9%).

Por que isso importa

Fruquintinib improved OS and PFS versus placebo in FRESCO-2 patients enrolled in Japan and demonstrated a manageable safety profile. Results from the Japan subgroup were consistent with the global FRESCO-2 population, thus supporting fruquintinib as a novel treatment option for patients in Japan with refractory mCRC.
