Second Line Treatment in <I>EGFR</I>/<I>ALK</I>-NSCLC Patients

e19166 Background: The efficacy of comparing the EGFR-TKI with standard chemotherapy in the second-line treatment of advanced NSCLC with wide-type EGFR were still controversial. To derive a more precise estimation of the two regimens, a meta-analysis was performed. Methods: Medical databases and conference proceedings were searched for randomized controlled trials which compared EGFR-TKI (gefitinib or erlotinib) with standard second-line chemotherapy (docetaxel or pemetrexed) in patients with NSCLC. Endpoints were overall survival, progression-free survival and overall response. Results: Three eligible trials (INTEREST, TITAN and TAILOR) were identified. Lacking for data of overall survival of TAILOR trial, So we only make a preliminary meta-analysis for overall survival. The intention to treatment (ITT) analysis demonstrated that the patients receiving EGFR-TKI had a significantly shorter progression-free survival (PFS) than patients treated with chemotherapy (hazard ratio (HR) = 1.31; 95% conﬁdence intervals (CI) = 1.10-1.56; P = 0.002). The overall survival (OS) and overall response rate (ORR) were coparable between this two groups (HR = 0.96; 95%CI = 0.77-1.19; P = 0.69; relative risk (RR) = 0.37; 95%CI = 0.09-1.54; P = 0.17). Conclusions: Although chemotherapy had a clear superiority in PFS as second-line treatment for patients without EGFR mutations compared with EGFR-TKI, OS and ORR were equal in this two regimens. The toxicity proﬁles might play an important role in the decision to choose EGFR-TKI or chemotherapy. These findings still need to be verified in larger confirmatory studies in future.

8042 Background: Pemetrexed or gefitinib is one of the standard second-line treatments for advanced non-squamousNSCLC in East Asia. The CTONG 0806 a multi-center, randomized, controlled, open-label phase II trial was designed to explore the efficacy of pemetrexed versus gefitinib as the second-line treatment in advanced NSCLC patients without EGFR mutation. Methods: The patients with locally advanced or metastatic, non-squamous NSCLC previously treated with platinum-based chemotherapy and no EGFR mutation in exons 18-21 were enrolled. Patients were 1:1 randomized to receive either gefitinib 250 mg per oral every day (G arm) or pemetrexed 500 mg/m2 iv day 1 with vitamin B12 and folic acid supplement every 21 days (P arm) until disease progression, unacceptable toxicity, or discontinuation of treatment due to other reason. The primary endpoint was progression-free survival (PFS). The secondary endpoints were 4-month and 6-month progression-free survival rate, overall survival (OS), objective response rate (ORR), quality of life using the FACT-L questionnaire and safety, EGFR and K-ras mutation status were evaluated and correlated with outcomes. Results: From Feb. 2009 to Aug. 2012, 157 evaluable patients were randomized (81 cases in G arm and 76 in P arm). Baseline age, gender, and ECOG performance status were balanced between arms. The primary endpoint of PFS was met with 1.6 months for G arm versus 4.8 months for P arm, the HR is 0.51 (95% CI 0.36~0.73, P<0.001). Overall response rates were 14.7 % and 13.3 % (P=0.814) and DCR were 32.0% and 61.3% (P<0.001) for G arm and P arm, respectively. OS data were not yet mature. More skin rash and diarrhoea were seen in G arm, but more fatigue and ALT increased in P arm. CTCAE grade 3 or 4 of AEs was 12.3% in G arm and 32.9% in P arm (p=0.002). The further analyses of efficacy evaluated by IRR and biomarkers analysis will be presented on the ground. Conclusions: CTONG0806 is the first trial to show significant improvements in PFS and DCR with pemetrexed compared with gefitinib in second-line setting for advanced NSCLC with EGFR wild type. Patients with EGFR wild type did not benefit from EGFR TKI gefitinb in second-line setting. Clinical trial information: NCT00891579.

Second-line treatment options for advanced/metastatic non-small cell lung cancer (NSCLC) patients are limited. We aimed to evaluate the efficacy and safety of docetaxel/sodium cantharidinate combination vs. either agent alone as second-line treatment for advanced/metastatic NSCLC patients with wild-type or unknown EGFR status. A randomized, open-label, phase III study was performed at 12 institutions. Patients with failure of first-line platinum regimens were randomized to receive either single-agent sodium cantharivsdinate (SCA) or single-agent docetaxel (DOX) or docetaxel/sodium cantharidinate combination (CON). The primary endpoints were centrally confirmed progression-free survival (PFS) and overall survival (OS). The secondary endpoints were objective response rate (ORR), disease control rate (DCR), quality of life (QoL) and toxicity. A total of 148 patients were enrolled in our study between October 2016 and March 2020. After a median follow-up time of 8.02 months, no significant difference was observed among the three groups in ORR (SCA vs. DOX vs. CON: 6.00% vs. 8.33% vs. 10.00%, respectively; p=0.814) and DCR (74.00% vs. 52.00% vs. 62.50%, respectively; p=0.080). In additional, the mOS was significantly higher in the CON group, compared with the single-agent groups (7.27 vs. 5.03 vs. 9.83 months, respectively; p=0.035), while no significant differences were observed in terms of PFS (2.7 vs. 2.9 vs. 3.1 months, respectively; p=0.740). There was no significant difference in the baseline QoL scores between the three groups (p>0.05); after treatment, life quality in SCA and CON group was significantly better than that in the DOX group (p<0.05). Furthermore, the incidence of adverse events (AEs) in the SCA group was significantly lower (46.00 vs. 79.17 vs. 25.00%, respectively; p=0.038) and the incidence of grade ≥3 AEs was also significantly lower in the SCA group compared with the DOX and CON groups (10.00 vs. 82.00 vs. 30.00%, respectively; p=0.042). Single-agent SCA and single-agent DOX has similar therapeutic efficacy in the second-line treatment of advanced/metastatic NSCLC with wild-type or unknown EGFR status, but single-agent SCA has fewer AEs and better QoL. Also, SCA plus DOX can significantly improve OS and exerted a significant synergistic effect, with good safety and tolerance profile.
