D chemotherapy; the remaining received docetaxel (these sufferers received pemetrexed as a part of their prior chemotherapy regimen). Patient qualities were nicely balanced among study arms (Table 1) except additional female sufferers were accrued to arm A (p 5 .075).

In arm A, 13 of 24 sufferers had received erlotinib alone earlier to study enrollment (10 of 20 sufferers in arm B), when 11 of 24 received erlotinib soon after frontline chemotherapy (ten of 20 in arm B) before study therapy. Even so, no patient had received pemetrexed or docetaxel prior to study enrollment (depending on which chemotherapy was administered on this trial). The imply time on initial EGFR TKI was 18 months for arm A versus 16 months for arm B prior to study enrollment. In both arms, prices of partial response and stable illness throughout prior EGFR-TKI therapy have been 65 and 35 , respectively. EGFR status was recognized for 39 on the 46 individuals (85 ) and 80 of your subjects with identified EGFR status had tumors that harbored an activating EGFR mutation. Seventeen patients in arm A and 14 individuals in arm B had documented EGFR-mutated tumors (all patients with documented mutations had classic exon 19 and 21 mutations). Of note is that the study was initiated at a time when EGFR mutation testing was not yet routinepractice, accounting for the couple of subjects with unknown EGFR status.Efficacy EvaluationThe median progression-free survival (the major endpoint with the study) of patients in arm A was 5.5 months, even though in arm B, it was 4.4 months; there was no statistically substantial distinction between the arms (p 5 .699) (Table 2, Fig. 1). The median overall survival in arm A was 16.four months and for arm B, it was 14.two months (p five .369). Subset analyses have been restricted to sufferers who had been documented as EGFR-mutation optimistic and no difference in progression-free or general survival (p five .332 [Fig. 2], and p five .346, respectively) was noted involving the arms within this subset, either. Inside the mutation-positive patients, 6-month survival was 39 in arm A and 32 in arm B.The general response rate was 15 for the entire study group and related involving the 2 groups: 13 for arm A and 17 for arm B (p five .37). Illness control rate (response plus steady illness) was 94 for the all round group, 100 for arm A, and 89 for arm B. Subgroup evaluation of individuals with recognized EGFR mutation status showed that the response prices for all those constructive for EGFR mutation and these damaging for EGFR mutation were 14.three and 16.7 , respectively (p five .885). No documented situations of tumor flare were noted in arm A of study therapy.Figure 1. Graphs of Kaplan-Meier estimations. (A): Progression-free survival in treatment arms.
