      114P - Phase II study of nivolumab in patients with advanced non-small cell lung cancer (NSCLC) in Korea (ID 441)

      12:30 - 12:30  |  Author(s): K. Park

      • Abstract

      Background:
      Nivolumab (BMS-936558/ONO-4538), a fully human IgG4, PD-1 immune-checkpoint inhibitor antibody, has shown durable clinical activity in several tumor types. Recently, two phase III studies (CheckMate-017 and -057) demonstrated that nivolumab improved overall survival (OS) than docetaxel in second-line of squamous (SQ) and non-squamous (NSQ) Non-Small Cell Lung Cancer (NSCLC), respectively. Here, we report the results of a phase II study to evaluate the efficacy and safety of nivolumab in Korean patients (pts) with previously treated advanced SQ and NSQ NSCLC.

      Methods:
      This study requires pts aged ≥ 20 years with ECOG Performance Status (PS) of 0 or 1, stage IIIB/IV or recurrent NSCLC and at least one prior chemotherapy including platinum containing regimen. Pts received nivolumab 3 mg/kg IV Q2W until progression or unacceptable toxicity. The primary endpoint in this study was the objective response rate (ORR) (RECIST v1.1).

      Results:
      Nivolumab was administered to 100 NSCLC pts (SQ: 44, NSQ: 56), male/female: 78 (SQ: 44, NSQ: 34)/22 (SQ: 0, NSQ: 22); PS 0/1: 14 (SQ: 6, NSQ: 8)/86 (SQ: 38, NSQ: 48); aged 29 to 80 [median: 66.5] years (SQ: 40 to 80 [median: 69.5], NSQ: 29 to 77 [median: 63.5]); Stage IIIB/IV/recurrence: 6 (SQ: 5, NSQ: 1)/91 (SQ: 37, NSQ: 54)/3 (SQ: 2, NSQ: 1)). In SQ and NSQ NSCLC, ORR was 15.9% (7/44) and 23.2% (13/56), respectively. Median progression-free survival was 2.6 mo and 5.3 mo, respectively. Complete Response was observed in 2.3% (1/44) and 1.8% (1/56), respectively. Median OS was 12.3 mo and 16.3 mo, respectively. Median follow-up was 8.9 mo and 12.3 mo, respectively. Most common adverse drug reaction (ADR) was decreased appetite 15.9% (7/44), followed by pyrexia 9.1% (4/44) in SQ NSCLC, and decreased appetite 12.5% (7/56), followed by pruritus 10.7% (6/56), fatigue 8.9% (5/56), pyrexia 5.4% (3/56) and nausea 5.4% (3/56) in NSQ NSCLC. Grade 3-4 ADR was observed in 6.8% (3/44) and 10.7% (6/56) of SQ and NSQ NSCLC, respectively. No interstitial lung disease and no grade 5 ADRs were observed in this study.

      Conclusions:
      Nivolumab was considered to be effective and used safely in Korean pts with SQ and NSQ NSCLC as well as in non-Korean pts with SQ and NSQ NSCLC.

      92PD - First-line afatinib for advanced EGFRm+ NSCLC: Analysis of long-term responders (LTRs) in the LUX-Lung (LL) 3, 6 and 7 trials (ID 299)

      15:15 - 15:15  |  Author(s): K. Park

      • Abstract

      Background:
      In the Phase III LL3 and LL6 trials, first-line afatinib significantly improved PFS and ORR versus platinum-doublet chemotherapy in pts with EGFRm+ NSCLC. In the Phase IIb LL7 trial, afatinib significantly improved PFS, time to treatment failure, and ORR versus gefitinib in this setting. Here we present post-hoc analyses of afatinib LTRs (treated with afatinib ≥3 years) in LL3/6/7.

      Methods:
      Treatment-naïve pts with stage IIIB/IV EGFRm+ NSCLC who were randomized to 40 mg/day afatinib in LL3/6/7 were included.

      Results:
      24/229 (10%), 23/239 (10%) and 19/160 (12%) afatinib-treated pts in LL3, LL6 and LL7 were LTRs; 6, 9 and 14 LTRs were still on treatment at the time of analysis. In LL7, 4% of gefitinib-treated pts were LTRs. Baseline characteristics were generally consistent with the overall study populations, with the exception of greater proportions of women (LL3/6 only; 92/78% vs 64% in the overall populations) and Del19+ pts (63–79% vs 49–58% overall) among LTRs. The table shows treatment duration and outcomes. The median OS values for LL3/6 were >30 months longer than those reported in the overall populations. ORRs ranged from 70.8% in LL3 to 89.5% in LL7. Frequency and duration of subsequent therapy was similar to the overall population. Frequency of afatinib dose reduction due to TRAEs was broadly consistent with the overall populations; final afatinib doses of 20/30/40/50 mg were observed in 50/25/21/4% in LL3, 13/22/61/4% in LL6, and 32/21/47/0% in LL7.

      Conclusions:
      In the LL3/6/7 studies, 10–12% of afatinib-treated pts were LTRs (treated ≥3 years). Among these pts, greater proportions of women (LL3/6 only) and Del19+ NSCLC were observed. In LTRs, afatinib conferred a long-term survival benefit of ∼5 years and was well tolerated. Long-term treatment was independent of tolerability-guided dose adjustment, or the presence of brain metastases at time of enrolment, and had no detrimental impact on subsequent treatment.rnTable: 92PDrn
