MA14.06 - Nivolumab in Never Smoker Patients with Advanced Squamous NSCLC: Results from the Italian Expanded Access Programme (EAP) (ID 4765)
16:36 - 16:42 | Author(s): P. Bordi

- Presentation
Background:
Nivolumab is the first checkpoint inhibitor approved for the treatment of Sq-NSCLC to show a survival benefit vs the standard of care docetaxel in the randomised, phase III, CheckMate 017 study. In the nivolumab development program, a greater clinical benefit was shown in current and former smokers than in never smokers. Nevertheless, no data are available in this respect from a real world setting. For this reason, we decided to use the data collected in the EAP in order to assess the effectiveness and tolerability of nivolumab treatment in the never smoker patient population.
Methods:
Nivolumab was provided upon physician request for patients aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for <24 months. Patients included in the analysis had received ≥1 dose of nivolumab and were monitored for adverse events using Common Terminology Criteria for Adverse Events.
Results:
Of 372 patients with Sq-NSCLC participating in the EAP in Italy, 38 (10.2%) were never smokers, a proportion very similar to the one observed in Checkmate 017 (10%). With a median number of doses of 8 (range, 1–22) and a median follow-up of 5.6 months, the disease control rate in this group was 50%, including 9 patients with a partial response and 10 with stable disease. Eight patients were treated beyond RECIST-defined progression, with 4 of them achieving disease control. As of April 2016, median progression-free survival and overall survival were 3.5 months and not reached, respectively. 17 patients (44.7%) discontinued treatment for any reason except toxicity and 5 (13.1%) discontinued due to AE.
Conclusion:
These preliminary results, although obtained from a small sample size, suggest that nivolumab is effective and well tolerated in a never smoker group of patients with advanced Sq-NCLCS in the real life and warrant further investigation in this area.

P2.03b-063 - Molecular Profiling in Advanced Non-Small-Cell Lung Cancer: Preliminary Data of an Italian Observational Prospective Study (ID 4529)
14:30 - 14:30 | Author(s): P. Bordi
- Abstract
Background:
Molecular profiling of advanced non-small-cell lung cancer (NSCLC) is recommended according to patients’ histological and clinical features. Despite the existence of national guidelines, routine care is still heterogeneous. Aim of this observational study was to obtain prospectively a clinical practice picture of molecular testing and therapeutic choices in advanced NSCLC patients.
Methods:
Newly diagnosed metastatic or recurrent NSCLC patients enrolled in 38 Italian centres, from November 2014 to November 2015, have been included in the study. Baseline information were collected about molecular profiling performed and therapies.
Results:
A total of 1787 patients were enrolled (64% males, 36% females; median age 67 years-old; 22% never smokers, 31% current smokers, 47% former smokers; 75% adenocarcinoma, and 73% with PS ECOG 0 or 1). The 73.9% of diagnosis was histological, while 26.1% was cytological. 1382 (77%) patients were tested for one or more molecular analysis during the history of disease, for a total of 3532 molecular tests. Only 405 patients did not receive any molecular test. 32.3% of patients presented a genetic alteration: EGFR mutation was reported in 17.8% of cases (319/1787), ALK translocation in 8.8% (82/926), KRAS mutation in 31.9% (154/482), MET amplifications in 15.8% (10/63), BRAF mutations in 3.7% (9/241), ROS1 translocation in 4% (11/269), HER2 mutation in 3.3% (3/89) of cases and FGFR alteration was found in 3 cases (only 15 tested). Considering patients younger than 45 years, never smokers and females, an EGFR mutation was detected in 25.4%, 43.5% and 30.6%, respectively. While 15.6%, 9.5% and 6.3% were ALK rearranged, respectively. For patients receiving an EGFR tyrosine-kinase inhibitor as first-line treatment, among those whose data are evaluable (79.2%), the median interval from diagnosis to first-line was 35 days. EGFR mutated patients received first-line erlotinib, gefitinib and afatinib in 9.4%, 39.1% and 33.8% of cases, respectively. At time of analysis, ALK-rearranged patients received an ALK inhibitor (crizotinib, alectinib or ceritinib) as first and/or second-line in 71.9% of cases. 29.3% of all patients received a maintenance therapy, mainly with pemetrexed (91.2% of cases).
Conclusion:
Routine molecular assessing is properly performed according to the national guidelines. A selection bias in including only those patients performing molecular tests, may explain the high proportion of patients with a molecular alteration. The low number of patients tested for ALK could be partially related to the impossibility to prescribe Crizotinib in first- line. In more than 70% of cases EGFR mutated patients received gefitinib or afatinib as first-line treatment.
