Overall survival with cisplatin–gemcitabine and bevacizumab or placebo as first-line therapy for nonsquamous non-small-cell lung cancer: results from a randomised phase III trial (AVAiL)
% B1 V; P1 D e8 w6 Z2 ~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. & m3 H$ x: B- D1 I0 l- U
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. 0 \+ L& b1 ~# _: ]' V- h0 Z
