Abstract 3240

Background

TAGS, a randomised, double-blind, phase III study, showed that FTD/TPI significantly improved overall survival (OS) and progression-free survival (PFS) compared with placebo in heavily pretreated mGC patients (pts) receiving best supportive care. The aim of this analysis was to evaluate the effects of FTP/TPI in the European subpopulation of TAGS.

Methods

TAGS enrolled pts with histologically confirmed, non-resectable mGC, Eastern Cooperative Oncology Group (ECOG) performance status 0/1, and ≥2 prior chemotherapy regimens. Pts were randomised 2:1 to FTD/TPI (35 mg/m2 BID on days 1–5 and 8–12 every 28 days) or placebo. Primary endpoint was OS. Secondary endpoints included PFS, time to deterioration (TTD) of ECOG and safety; 507 pts were randomised to FTD/TPI (n = 337) or placebo (n = 170). Median follow-up was 10.7 months.

Results

277 pts (mean age 63.0 years; 75% male) were enrolled from 64 sites in Europe. Baseline characteristics were balanced between groups; 120 (67%) and 63 (65%) of pts in FTD/TPI and placebo groups had received ≥3 regimens of prior systemic therapy. FTP/TPI significantly prolonged OS (hazard ratio [HR] 0.59, 95% confidence interval [CI] 0.44-0.78), PFS (HR 0.46, 95% CI 0.35–0.61) and TTD to ECOG (HR 0.59, 95% CI 0.45–0.78; Table) compared with placebo. FTD/TPI had a predictable and manageable safety profile. Treatment-emergent adverse events (TEAEs) were reported in 172/180 (96%) FTD/TPI-treated and 92/97 (96%) placebo-treated pts.

Conclusions
