Background: Bevacizumab, the anti-vascular endothelial growth factor agent, provides clinical benefit when combined with platinum-based chemotherapy in first-line advanced non-small-cell lung cancer. We report the final overall survival (OS) analysis from the phase III AVAiL trial. Patients and methods: Patients (n = 1043) received cisplatin 80 mg/m2 and gemcitabine 1250 mg/m2 for up to six cycles plus bevacizumab 7.5 mg/kg (n = 345), bevacizumab 15 mg/kg (n = 351) or placebo (n = 347) every 3 weeks until progression. Primary end point was progression-free survival (PFS); OS was a secondary end point. Results: Significant PFS prolongation with bevacizumab compared with placebo was maintained with longer follow-up {hazard ratio (HR) [95% confidence interval (CI)] 0.75 (0.64–0.87), P = 0.0003 and 0.85 (0.73–1.00), P = 0.0456} for the 7.5 and 15 mg/kg groups, respectively. Median OS was >13 months in all treatment groups; nevertheless, OS was not significantly increased with bevacizumab [HR (95% CI) 0.93 (0.78–1.11), P = 0.420 and 1.03 (0.86–1.23), P = 0.761] for the 7.5 and 15 mg/kg groups, respectively, versus placebo. Most patients (∼62%) received multiple lines of poststudy treatment. Updated safety results are consistent with those previously reported. Conclusions: Final analysis of AVAiL confirms the efficacy of bevacizumab when combined with cisplatin–gemcitabine. The PFS benefit did not translate into a significant OS benefit, possibly due to high use of efficacious second-line therapies.
