Aim:  The phase III AVAiL study evaluated the efficacy and safety of the anti-vascular epidermal growth factor agent bevacizumab combined with platinum-based chemotherapy as first-line treatment in patients with advanced non–small-cell lung cancer (NSCLC). We report the results of a preplanned analysis of Asian patients enrolled in AVAiL.

Methods:  Patients with recurrent or advanced non-squamous NSCLC were randomized to receive bevacizumab 7.5 mg/kg, bevacizumab 15 mg/kg or placebo, plus cisplatin 80 mg/m2 and gemcitabine 1250 mg/m2 for up to six cycles, followed by bevacizumab or placebo until disease progression. An exploratory analysis was undertaken to assess efficacy and safety in an Asian subgroup.

Results:  Of the 1043 patients enrolled, 105 were Asian and were included in the subgroup analysis. Progression-free survival was 8.5 months (95% CI 7.3–10.8) in the bevacizumab 15-mg/kg group, 8.2 (95% CI 6.6–11.7) in the 7.5-mg/kg group and 6.1 (95% CI 5.1–8.0) in the placebo group. Median overall survival in the 7.5-mg/kg bevacizumab group was prolonged compared with placebo group (HR 0.46; 95% CI 0.22–0.97). Nausea was the most common adverse event, occurring at similar rates (ranging from 69–76%) in all study groups. Hypertension was the most common adverse event of special interest, seen in 29, 55 and 16% of patients in the 7.5-mg/kg and 15-mg/kg bevacizumab and placebo groups, respectively.

Conclusion:  Study results strongly suggest that bevacizumab at a dose of 7.5 mg/kg improves the duration of overall survival when combined with cisplatin-gemcitabine in Asian patients. Bevacizumab was well tolerated in this patient group.
