Partial response.
Survival was censored at last follow-up or at final analysis.
Response was assessable in 418 patients: 215 in monotherapy group and 203 in doublet chemotherapy group.
Sample size in PFS group.
HR for death or disease progression with gefitinib, 0.36; P < .001.

TTP.
Median OS from time of first induction (median, 10.9 months follow-up).
Treatment difference in best overall response rate, 5.5% (95% CI, 7.3% to 18.2%; P = .878).
Investigator assessed.
Per protocol: 222 v 221 (patients with no majority protocol violations with at least one dose of drug).
Started treatment.
Evaluable patients.
Data for OS were not yet mature; 88 were still in follow-up as of January 2011.
EGFR positive: 21.6 v 21.9 (HR, 1; 95% CI, 0.76 to 0.133).
Preliminary (death threshold not yet reached).
At time of data cutoff, investigators had observed 238 PFS events, with median PFS of 11.1 months for afatinib and 6.7 months for chemotherapy (HR, 0.49; 95% CI, 0.37 to 0.65; P = .001).
