    Abstract: ADJUVANT-CTONG1104 (ClinicalTrials.gov identifier: NCT01405079 ), a randomized phase III trial, showed that adjuvant gefitinib treatment significantly improved disease-free survival (DFS) versus vinorelbine plus cisplatin (VP) in patients with epidermal growth factor receptor ( EGFR) mutation-positive resected stage II-IIIA (N1-N2) non–small-cell lung cancer (NSCLC). Here, we report the final overall survival (OS) results. METHODS From September 2011 to April 2014, 222 patients from 27 sites were randomly assigned 1:1 to adjuvant gefitinib (n = 111) or VP (n = 111). Patients with resected stage II-IIIA (N1-N2) NSCLC and EGFR-activating mutation were enrolled, receiving gefitinib for 24 months or VP every 3 weeks for four cycles. The primary end point was DFS (intention-to-treat [ITT] population). Secondary end points included OS, 3-, 5-year (y) DFS rates, and 5-year OS rate. Post hoc analysis was conducted for subsequent therapy data. RESULTS Median follow-up was 80.0 months. Median OS (ITT) was 75.5 and 62.8 months with gefitinib and VP, respectively (hazard ratio [HR], 0.92; 95% CI, 0.62 to 1.36; P = .674); respective 5-year OS rates were 53.2% and 51.2% ( P = .784). Subsequent therapy was administered upon progression in 68.4% and 73.6% of patients receiving gefitinib and VP, respectively. Subsequent targeted therapy contributed most to OS (HR, 0.23; 95% CI, 0.14 to 0.38) compared with no subsequent therapy. Updated 3y DFS rates were 39.6% and 32. 5% with gefitinib and VP ( P = .316) and 5y DFS rates were 22. 6% and 23.2% ( P = .928), respectively. CONCLUSION Adjuvant therapy with gefitinib in patients with early-stage NSCLC and EGFR mutation demonstrated improved DFS over standard of care chemotherapy. Although this DFS advantage did not translate to a significant OS difference, OS with adjuvant gefitinib was one of the longest observed in this patient group compared with historic data.

    Abstract: 9005 Background: ADJUVANT-CTONG1104, a randomized phase 3 trial showed adjuvant gefitinib treatment significantly improved disease-free survival (DFS) vs standard doublet chemotherapy in patients (pts) with epidermal growth factor receptor ( EGFR) mutation-positive resected stage II-IIIA (N1-N2) non-small-cell lung cancer (NSCLC). 5-year survival rate of N1N2 were 38%-50% in IASLC staging system. Here, we present the final overall survival (OS) results from the study. Methods: From Sep 2011 to April 2014, 222 patients, aged 18-75 years, with EGFR activating mutation through completely resection and diagnosed as stage II-IIIA (N1-N2) NSCLC pathologically from 27 sites were enrolled. The enrolled patients were 1:1 randomized to receive adjuvant gefitinib (250 mg once per day) for 24 months (G, n=111) or vinorelbine (25 mg/m 2 , d1 and d8) plus cisplatin (75 mg/m2, d1) every 3 weeks for 4 cycles (C, n=111). The primary endpoint was DFS in the ITT population. Secondary endpoints included OS, 3 and 5-year DFS rate, 5-year OS rate. The subsequent therapy data were collected, including crossover from C to G, re-challenge TKI and other treatment. Data cut-off date was Jan. 13, 2020. Results: A median follow-up was 76.9 months. The median OS (mOS) was 75.5 months based on 95 (42.8%) events in ITT whole population. The mOS was 75.5m in G arm and 79.2m in C arm (HR 0.96, 95%CI 0.64-1.43, p=0.823). The 3, 5-year OS rate were 68.6%, 53.8% in G and 67.5%, 52.4% in C respectively. DFS in 3, 5-y were 40.3%, 23.4% in G and 33.2%, 23.7% in C, respectively (P 3-y =0.395, P 5-y =891). All predefined subgroups including age, gender, lymph node, EGFR mutation type had no significant difference in statistics but in favor of G arm in trend. Subsequent treatment especially targeted therapy contributed most to OS (HR = 0.46, 95% CI 0.26 – 0.83). Median OS of patients receiving subsequent target therapy was75.5m (n=35), 36.4m in other treatment (n=33; (P 〈 0.001). For G mOS were 75.5 (n=15; target therapy) and 35.0 (n=18; other, p 〈 0.001), for C 62.8m (n=20) and 46.8m (n=15; p=0.251). The RR was 26.7%, DCR 66.7%, mPFS 14.1m and mOS 19.6m for patients with rechallenged EGFR TKI in G arm (n=15). No novel unexpected SAE was observed during follow up. Conclusion The DFS survival advantage did not translate to OS difference in ADJUVANT trial. The OS with 75.5m was the best one of survival in completely resected N1N2 NSCLC comparing with historical data and sequent TKI treatment contribute to overall survival. Clinical trial information: NCT01405079.

    Abstract: To assess the benefits of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as neoadjuvant/adjuvant therapies in locally advanced EGFR mutation-positive non–small-cell lung cancer. PATIENTS AND METHODS This was a multicenter (17 centers in China), open-label, phase II, randomized controlled trial of erlotinib versus gemcitabine plus cisplatin (GC chemotherapy) as neoadjuvant/adjuvant therapy in patients with stage IIIA-N2 non–small-cell lung cancer with EGFR mutations in exon 19 or 21 (EMERGING). Patients received erlotinib 150 mg/d (neoadjuvant therapy, 42 days; adjuvant therapy, up to 12 months) or gemcitabine 1,250 mg/m 2 plus cisplatin 75 mg/m 2 (neoadjuvant therapy, two cycles; adjuvant therapy, up to two cycles). Assessments were performed at 6 weeks and every 3 months postsurgery. The primary end point was objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1; secondary end points were pathologic complete response, progression-free survival (PFS), overall survival, safety, and tolerability. RESULTS Of 386 patients screened, 72 were randomly assigned to treatment (intention-to-treat population), and 71 were included in the safety analysis (one patient withdrew before treatment). The ORR for neoadjuvant erlotinib versus GC chemotherapy was 54.1% versus 34.3% (odds ratio, 2.26; 95% CI, 0.87 to 5.84; P = .092). No pathologic complete response was identified in either arm. Three (9.7%) of 31 patients and zero of 23 patients in the erlotinib and GC chemotherapy arms, respectively, had a major pathologic response. Median PFS was significantly longer with erlotinib (21.5 months) versus GC chemotherapy (11.4 months; hazard ratio, 0.39; 95% CI, 0.23 to 0.67; P 〈 .001). Observed adverse events reflected those most commonly seen with the two treatments. CONCLUSION The primary end point of ORR with 42 days of neoadjuvant erlotinib was not met, but the secondary end point PFS was significantly improved.

    Abstract: 8502 Background: Median Overall survival (mOS) of stage IIIA resected NSCLC was 59.4 months (m) in CTONG 1104 adj gefitinib and 26.2m in SAKK neoadjuvant chemo trial. EMERGING-CTONG1103 showed neo-adjuvant/adjuvant erlotinib treatment significantly improved progression-free survival (PFS) vs standard doublet chemotherapy in patients (pts) with epidermal growth factor receptor ( EGFR) mutation-positive resectable stage IIIA (N2) non-small-cell lung cancer (NSCLC). Here, we present the final overall survival (OS) results from the study. Methods: This was a multicenter (17 centers in China) phase II randomized controlled trial of erlotinib（E）versus gemcitabine plus cisplatin (GC) as neoadjuvant/adjuvant therapy in pts with stage IIIA-N2 NSCLC with EGFR mutations in exon 19 or 21. From Dec 2011 to Dec. 2017, 386 pts sites were screened and 72 pts were randomly assigned to neoadjuvant/adjuvant E arm (N = 37) or GC arm(N = 35). Patients received erlotinib 150 mg/d (neoadjuvant therapy, 42 days; adjuvant therapy, up to 12 months) or gemcitabine 1,250 mg/m 2 plus cisplatin 75 mg/m 2 (neoadjuvant therapy, two cycles; adjuvant therapy, up to two cycles). Assessments were performed at 6 weeks and every 3 months postoperative. The primary end point was objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1; secondary end points were pathologic complete response, downstaging rates of pathological lymph nodes, PFS, OS, safety, and tolerability. Data cut-off date was January, 29 2021. Results: With a median follow-up of 62.5 months, the median OS was 42.2months based on 47 (65.3%) events in ITT whole population. The mOS was 42.2m in E and 36.9m in GC (HR 0.83, 95%CI 0.47-1.47, p = 0.513). The 3-,5-year OS rate were 58.6%, 40.8% in E and 55.9%, 27.6% in GC respectively (p3-y = 0.819, p5-y = 0.252). All predefined subgroups including age, gender, EGFR mutation type had no significant difference in statistics between two arms. Subsequent treatments (ST) especially targeted therapy contributed most to OS (HR = 0.35,95% CI 0.18- 0.70). Median OS of pts receiving ST was 45.8m (n = 38), 34.6m in other treatment (n = 12), 24.6m in without ST (n = 15). For E mOS were 46.4 (n = 15; target therapy), 42.2m (n = 8; other) and 24.6m (n = 9; without, p = 0.021), for GC 42.6 (n = 23; target therapy), 30.1m (n = 4;other) and 24.6m(n = 6; without, p = 0.130). The RR was 53.3%, DCR 93.3%, mPFS 10.9m and mPPS 21.9m for patients with rechallenged EGFR TKI in E arm (n = 15). No novel unexpected SAE was observed during follow up. Conclusion: Erlotinib as neoadjuvant/adjuvant therapy for resected N2 NSCLC was feasibility and had a promising OS. The PFS survival advantage of E did not translate to OS difference in EMERGING trial (NCT01407822). Clinical trial information: NCT01407822.
