      Background:
      Concurrent chemoradiotherapy (CCRT) is the standard treatment (TRT) for stage 3 NSCLC. Elderly patients (pts) are common, may have increased toxicity,& poorer results from CCRT

      Methods:
      Individual patient data (IPD) from NCTN phase 2/3 trials of CCRT for stage 3 NSCLC from 1990-2012 was collected. We compared the overall survival (OS), progression-free survival (PFS), & adverse events (AE’s) for pts age ≥70 years (yrs) (elderly) vs. <70 yrs (younger). Unadjusted & adjusted Hazard Ratios (HRs) for survival time & their confidence intervals (CIs) were estimated by single-predictor & multivariable Cox models. Unadjusted & adjusted Odds Ratio (OR) for AE’s & their CIs were obtained from single-predictor & multivariable logistic regression models

      Results:
      IPD from 16 trials were analyzed; 2,768 pts were younger & 832 were elderly. Median OS & PFS for elderly & younger pts are in the table. In the unadjusted & multivariable models elderly pts had worse OS (HR=1.23; 95%CI =1.13-1.35, and 1.20; 95%CI=1.10-1.32, respectively). In the unadjusted & multivariable models, elderly & younger pts had a similar PFS (HR=1.02; 95% CI=0.94-1.11 and 1.01, 95% CI=0.92-1.10, respectively). Elderly pts had a higher rate of grade ≥3 AE’s in the unadjusted & multivariable models (OR=1.25; 95% CI=1.00-1.57 and 1.30; 95%CI=1.03-1.62, respectively). A lower percentage of elderly pts compared to younger completed TRT (47% and 57%, respectively; P<0.0001) & higher percentage stopped due to AE’s (20% and 13%; P<0.0001). Grade ≥ 3 AE’s (occurring at a rate ≥ 2.5%) with a higher rate in the elderly: neutropenia, dyspnea, fatigue, anorexia, vomiting, dehydration, hypoxia, hypotension, & pneumonitis (P<0.05).

      Age ≥ 70yrs Age < 70 yrs P-value[a]
      Median OS (months) 17.0 20.7 < 0.01
      Median PFS (months) 8.7 9.1 0.68
      All toxicities grade ≥3 86% 84% 0.04
      Hematologic AE’s grade ≥3 65% 61% 0.04
      Non-hematologic AE’s ≥3 68% 62% <0.01
      Grade 5 AE’s 9.0% 4.4% <0.01
      TRT related deaths[b] 3.2% 2.0% 0.12
      a: Log-rank test for survival times, chi-square test for AE’s, and Fisher’s exact test for deaths. The P-values from these tests are unadjusted. b: Data available on 2,091 patients

      Conclusion:
      Elderly pts in CCRT trials had worse OS, similar PFS, & a higher rate of severe AE's.

      P2.02-037 - Final Results of Prospective Phase II Study of Adding Erlotinib to Chemoradiation for patients with Stage III Non-Small-Cell Lung Cancer (ID 5748)

      14:30 - 14:30  |  Author(s): G. Blumenschein

      • Abstract

      Background:
      Concurrent chemoradiotherapy is the standard of care for inoperable stage III non-small cell lung cancer (NSCLC) patients. We explored if adding erlotinib would increase the effectiveness of chemoradiotherapy, since we have demonstrated radiation sensitization by erlotinib in a preclinical setting using a mouse model.

      Methods:
      48 patients with stage III NSCLC, PS 0-1, received radiotherapy (63 Gy/35 fractions) on Monday‒Friday, with chemotherapy (paclitaxel 45 mg/m², carboplatin AUC=2) on Mondays, for 7 weeks. All patients also received EGFR-TKI erlotinib (150 mg orally 1/day) on Tuesday–Sunday for 7 weeks followed by consolidation paclitaxel–carboplatin. The primary endpoint was time to progression; secondary endpoints were overall survival (OS), toxicity, response, and disease control and whether any endpoint differed by EGFR mutation status.

      Results:
      46 out of 48 patients were evaluable for response; 40 were former or never smokers and 41 were evaluated for EGFR mutation status: 37 were wild-type and 4 were found to have mutation (3 exon 19 deletion, 1 exon 21 mutation). Median time to progression was 14 months and did not differ based on EGFR mutation status. Toxicity was acceptable: no grade 5 toxicity, I grade 4, and 11 grade 3). Twelve (26%) had complete responses (10 with wild type (wt) and 2 with mutation (mt) and 1 unknown). At 73.5 months median follow-up (range 46.2 - 93.7 months), 2 and 5 year OS rates were 67.4 % and 36.25%; there were no significant differences by mutation status. Twelve patients had no progression and 34 had local and/or distant metastasis. All 4 patients with EGFR mutation had local control. Eleven of 27 patients failed in the brain (7 wt, 3 mt and 1 unknown).

      Conclusion:
      Toxicity was acceptable and OS was promising, but time to progression did not meet expectations. The prevalence of distant failures underscores the need for effective systemic therapy. Those patients with EGFR mutation might need induction erlotinib followed by local treatment when they fail locally in the lung or brain which is fairly frequent among EGFR mutated patients.

      P2.06-027 - Randomized Phase II Study of Anetumab Ravtansine or Vinorelbine in Patients with Metastatic Pleural Mesothelioma (ID 5671)

      14:30 - 14:30  |  Author(s): G. Blumenschein

      • Abstract

      Background:
      Mesothelioma is a rare but aggressive cancer with a poor prognosis. Mesothelin is a cell surface protein that is highly expressed in mesothelioma and other epithelial cancers. Anetumab ravtansine (BAY 94-9343), a novel fully human anti-mesothelin IgG1 antibody conjugated to the maytansinoid tubulin inhibitor DM4, has shown encouraging efficacy in mesothelioma patients in a phase I study. To further explore the possible benefit of antibody-drug conjugate therapy for mesothelioma, we initiated a randomized, open-label, active-controlled, phase II trial to evaluate the efficacy and safety of anetumab ravtansine in patients with metastatic pleural mesothelioma (MPM) overexpressing mesothelin and who have previously progressed on platinum/pemetrexed-based first-line chemotherapy (NCT02610140).

      Methods:
      Patients (≥18 years) with unresectable locally advanced or metastatic MPM are eligible. Patients should have recurrent or relapsing disease after having previously receiving first-line treatment with pemetrexed-based chemotherapy, with or without bevacizumab. Obligatory biomarker sampling will be performed on all patients at pre-screening and mesothelin-positivity as determined by Ventana MSLN (SP74) companion diagnostic assay as a requirement for entry. The primary objective is to test the superiority of anetumab ravtansine monotherapy over vinorelbine in progression-free survival (PFS) per modified RECIST criteria for MPM per central review. The secondary objectives of this study include overall survival, patient-reported outcomes (PRO), tumor response, and safety. Exploratory objectives include immunogenicity of anetumab ravtansine, pharmacokinetics, and biomarkers of response. Approximately 210 patients will be randomized in a 2:1 ratio to receive anetumab ravtansine 6.5 mg/kg Q3W or vinorelbine 30 mg/m[2] QW. Novel study methods include a grading system for AEs of special interest and the PRO instruments.

      Results:
      This trial is open and currently accruing patients globally.

      Conclusion:
      Section not applicable.

      P3.02a-001 - Response and Plasma Genotyping from Phase I/II Trial of Ensartinib (X-396) in Patients (Pts) with ALK+ NSCLC (ID 6090)

      14:30 - 14:30  |  Author(s): G. Blumenschein

      • Abstract
      • Slides

      Background:
      Ensartinib (X-396) is a novel, potent anaplastic lymphoma kinase (ALK) small molecule tyrosine kinase inhibitor (TKI) with additional activity against MET, ABL, Axl, EPHA2, LTK, ROS1 and SLK. We report data on the ALK TKI-naïve and crizotinib (C)-resistant NSCLC pts treated with ensartinib. Clinical trial information: NCT01625234

      Methods:
      In this multicenter expansion study, pts with ALK+ NSCLC were treated with ensartinib 225 mg daily on a 28-day schedule. Pts had measurable disease, ECOG PS 0-1, and adequate organ function. Untreated brain metastases (CNS) and leptomeningeal disease were allowed. Next Generation Sequencing (NGS) was performed on plasma samples collected at baseline and on study and compared with central tissue results (FISH/IHC). All pts were assessed for response to therapy using RECIST 1.1 and for adverse events (AEs) using CTCAE version 4.03.

      Results:
      80 pts (51% female) have been enrolled. Median age 54 (20-79) years, 64% ECOG PS 1. Of 40 ALK+ NSCLC pts evaluable for response; partial response (PR) was achieved in 23 pts (58%) and stable disease (SD) in 8 pts (20%). In the C-naïve pts (n = 8), PRs were observed in 7 pts (88%). In the 22 pts with prior C but no other ALK TKI, 14 pts (64%) achieved PR and 6 (27%) SD. In the 10 pts who had received two or more prior ALK TKIs, there was 2 PR, 2 SD (40% DCR). CNS responses (50% PR) have been observed in both C-naïve and C-resistant pts. Plasma and tissue genotyping were available on 27 pts (26 ALK+ and 1 ALK-). ALK was detected in plasma in 16 pts, all of whom had a response to therapy. 2 pts with PD were tissue +ve and plasma -ve. 9 plasma samples were unevaluable. Serial sequencing demonstrated a decrease in ALK in pts responding and an increase at the time of progression. The most common drug-related AEs (≥ 20% of pts) included rash (53%), nausea (32%), vomiting (26%), fatigue (23%), and pruritus (21%). Most AEs were Grade (G) 1-2. The G3 treatment-related AEs were rash (8 pts), fatigue (2 pts), pruritus (2 pts), edema (2 pts), decreased appetite (1 pt), nausea (1pt), and vomiting (1pt).

      Conclusion:
      Ensartinib is well-tolerated with response in both C-naïve and C-resistant ALK+ NSCLC pts, as well as pts with CNS disease. Plasma sequencing appears to be promising to select pts for therapy and monitor for response and development of acquired resistance.
