PaFLO: Pazopanib with 5-fluorouracil, leucovorin, and oxaliplatin (FLO) as first-line treatment in advanced gastric cancer: A randomized phase II study of the  Arbeitsgemeinschaft internistische Onkologie (AIO).

TPS4138 Background: VEGF inhibition in gastric cancer shows promising improvement of remission rate and progression-free survival (Ohtsu et al., JCO 2011). Pazopanib is an orally available tyrosine kinase inhibitor (TKI) selectively inhibiting VEGFR-1, -2, -3, c-kit and PDGFR. It is approved for treating renal cell cancer. A phase-I trial showed good tolerability of pazopanib with full-dose FOLFOX in solid tumors (Brady et al., ASCO, 2009). FLO is a widely used combination for advanced gastric cancer recommended in national guidelines. Methods: 75 Patients with HER-2-negative locally advanced or metastatic adenocarcinoma of the stomach or the gastro-esophageal junction will be randomized i…
