      Background:
      Phase III trials have demonstrated the superiority of the ALK tyrosine kinase inhibitor (ALK-TKI) crizotinib compared to standard chemotherapy in advanced ALK positive non-small cell lung cancers (ALK+ NSCLC) in first line and second line setting. Objective response rate (ORR) with crizotinib ranged from 65 to 75% and median progression free survival (PFS) from 7.7 to 10.9 months. However a resistance to crizotinib always occurs. The French Cooperative Thoracic Intergroup (IFCT)-1302 CLINALK study aimed to describe clinical outcome and post-progression management in a large cohort of French patients with ALK+ NSCLC treated with crizotinib.

      Methods:
      IFCT-1302 CLINALK is a multicentric observational retrospective study. Patients with ALK+ NSCLC from centers of the IFCT network were included according to the main following criteria: advanced stage III or stage IV NSCLC, ALK immunochemistry (IHC) and/or ALK FISH positivity, crizotinib treatment in the setting of the French expanded access cohort program or as approved drug. Epidemiological and clinical data, crizotinib efficacy (objective response based on RECIST, PFS, overall survival (OS)), duration of treatment with crizotinib after disease progression and post progression outcome were collected on a case report form. The study inclusion period was from November 18 2011 to December 31 2013. The data cut-off was December 31 2014.

      Results:
      318 patients were included (median age 58.3, female 49.4%, caucasian 98.6%, non-smoker 55.1%, performance status 0/1 78.7%, adenocarcinoma 91.7%, stage III 14.5%, stage IV 85.5%, brain metastasis 35.9%). IHC was positive in 151/173 patients and FISH in 279/283 patients. Before crizotinib treatment, patients received platinum-based chemotherapy in 89% of cases and pemetrexed-based chemotherapy in 76.1%. Crizotinib was prescribed as first-line treatment in 17 patients (5.3%), second-line in 168 patients (52.8%), third-line in 58 patients (18.2%) and more than third-line in 75 patients (23.7%). Objective response was complete response in 1 patient (0.3%), partial response in 126 patients (40.0%), stable disease in 62 patients (19.7%) and progression in 58 patients (18.4%). ORR was 40.3 % (95%CI, 34.9-45.7). 262/318 patients presented progressive disease (82.4%) at time of analysis. Median PFS was 6.9 months (95%CI, 5.7-8.6). Median OS with crizotinib was 18.7 months (95%CI, 15.2-22.5). Median duration of treatment with crizotinib after disease progression was 56 days (29-203). Among 143 patients with subsequent treatments, crizotinib was rechallenged in 32 patients (22.4%). 58/143 patients (40.6%) were treated after crizotinib failure with another ALK-TKI, either alectinib (19/58, 32.8%) or ceritinib (40/58, 69.0%). The ALK-TKI sequence was crizotinib-alectinib in 18 patients, crizotinib-ceritinib in 39 patients and crizotinib-alectinib-ceritinib in 1 patient.

      Conclusion:
      This retrospective study of 318 patients with ALK+ NSCLC showed a remarkable efficacy of crizotinib, with a 18.7 months median OS, a 40.3% ORR and a 6.9 months median PFS. However, ORR and mPFS were lower than those reported in phase III trials, which may be due to less stringent selection criteria. Analysis of predictive factors of response and survival including post-progression strategies will be presented.

      P1.01-064 - A Phase II Study of Gemcitabine-Cisplatin plus Necitumumab for Stage IV Sq-NSCLC (ID 927)

      09:30 - 09:30  |  Author(s): J. Cadranel

      • Abstract
      • Slides

      Background:
      To report the efficacy and safety results from a study of necitumumab (N), manufactured under process D, modified from Process C, used in the pivotal SQUIRE study, in combination with gemcitabine (G) plus cisplatin (C) as first-line treatment in patients with advanced squamous non-small cell lung cancer (Sq-NSCLC). (NCT01788566)

      Methods:
      This was an open-label, single-arm, multicenter, phase II study in patients with advanced Sq-NSCLC. Patients were enrolled who were aged ≥18 years and had measurable, pathologically confirmed stage IV Sq-NSCLC without prior chemotherapy. Patients had ECOG-PS 0-1, adequate organ function, and life expectancy of ≥12 weeks. Patients received N (800 mg iv, Days 1 and 8) plus GC (G=1250 mg/m² iv, Days 1 and 8; C=75 mg/m² iv, Day 1) each 3-week cycle for up to 6 cycles. Patients with at least stable disease (SD) could continue to receive N alone until progressive disease (PD) or other discontinuation criteria. Primary endpoint was objective response rate (ORR) based on RECIST1.1. Secondary endpoints included overall survival (OS), progression-free survival (PFS), disease control rate (DCR), change in tumor size (CTS; % improvement in lesions), and safety.

      Results:
      Patients (N=61), median age 65 years, heavy metastatic disease burden; approximately 70% of the patients had metastases to ≥ 2 organ systems. Efficacy results, including an ORR of 48.1% are shown in the Table. Survival and PFS findings were similar to those reported in the SQUIRE study in the GC+N arm (SQUIRE results: median OS of 11.5 months, 1-year survival rate of 47.7%, and median PFS of 5.7 months). Median duration of treatment was 12 weeks (4 cycles) for G and C and 16 weeks (5 cycles) for N; the median relative dose intensity was 85% for G and 93% for C and N. Twenty-eight (46%) patients continued on single-agent N (median: 4 cycles). Skin reactions (n=49; 80.3%) and hypomagnesemia (n=21; 34.4%) were the most commonly reported adverse events of special interest (AESIs, all grades). AESI ≥ Grade 3 were skin reactions (n=8; 13.1%), thromboembolic events (n=7; 11.5%), hypomagnesemia (n=6; 9.8%), and hypersensitivity/ IRR (n=3; 4.9%). There were 27 deaths (20 due to PD and 7 due to AEs [5 had no causal relationship to study drug]) at the time of data cut-off.
