OA11.01 - Prolonged OS of Patients Exposed to Weekly Paclitaxel and Bevacizumab: Impact of the Cross-Over in the IFCT-1103 ULTIMATE Study (ID 4988)
11:00 - 12:30 | Author(s): O. Molinier
- Abstract
- Presentation
Background:
Overall survival (OS) is considered as the gold standard for evaluating efficacy of antineoplastic treatments, including chemotherapy and targeted therapies. In randomized trials, allowing patients to cross-over to the other arm usually prevents demonstration of a survival benefit. However, it may provide important information with clinical relevance.
Methods:
The phase III IFCT-1503 ULTIMATE study compared weekly paclitaxel and bevacizumab (wPB) vs. docetaxel (DOC) as second- or third-line therapy in non-squamous NSCLC. At progression, patients were allowed to cross over to the other arm. Date of progression was collected for patients who crossed over to the other arm and for those who did not cross over but received a post-discontinuation treatment within 60 days following progression. Post-discontinuation progression-free survival (PFS2) and OS2 were calculated from day 1 of post-discontinuation treatment.
Results:
The study met its primary endpoint, PFS, which was significantly improved in the wPB arm (medians 5.4 vs. 3.9 mo, hazard ratio (HR) 0.62, p=0.006). No overall survival was observed (medians 9.9 vs. 11.4 mo, HR 1.18, p=0.4). Out of patients treated with DOC (n=55), those who crossed over to wPB (n=21, 38.2%) had a median PFS2 of 4.9 mo [3.1-6.2] and a median OS2 of 12.5 mo (7.0-NR), whereas those who did not cross over but received a post-discontinuation treatment (n=13, 23.7%) had a median PFS2 of 1.7 mo [1.1-2.2] and a median OS2 of 4.1 mo [2.1-5.9]. Out of patients treated with wPB (n=111), median PFS2 was 1.9 mo [1.2-2.2] for those who crossed over to DOC (n=9, 8.3%) and median PFS2 and OS2 were 1.9 mo [1.7-2.6] and 5.0 m [3.4-9.0] for those who did not cross over but received a post-discontinuation treatment (n=57, 52.3%).
Conclusion:
Allowing patients to cross over to the other arm demonstrated benefit of wPB following progression on docetaxel and explains the absence of OS benefit.

OA23.02 - Efficacy and Safety of Necitumumab Continuation Monotherapy in Patients with EGFR-Expressing Tumors in SQUIRE, a Phase 3 Study (ID 4283)
14:20 - 15:50 | Author(s): O. Molinier
- Abstract
- Presentation
Background:
SQUIRE (NCT00981058) demonstrated adding necitumumab (N) to gemcitabine/cisplatin (GC) improved survival in patients with Stage IV squamous NSCLC (SQ-NSCLC). Retrospective analysis revealed consistent treatment effect in favor of patients receiving N monotherapy as continuation after chemotherapy (CT) (GC+N continuation patients) versus continuation therapy-eligible GC arm patients (GC non-progressors). In the EU, N is approved for patients with EGFR-expressing tumors. We repeated the analysis in this patient population.
Methods:
Patients with Stage IV SQ-NSCLC were randomized 1:1 for ≤6 cycles of G (1250 mg/m[2] iv, Days [d] 1,8) and C (75 mg/m[2] iv, d1) either with or without N (800 mg iv, d1,8). Patients in GC+N without progression continued N until progressive disease (PD). SQUIRE included mandatory tissue collection. EGFR protein expression was assessed by IHC in a central lab (Dako EGFR PharmDx kit). Analyses were done in EGFR-expressing patients (EGFR >0). Patients who received ≥4 cycles of CT without PD were included. Overall survival (OS) and progression-free survival (PFS) were calculated by Kaplan-Meier method. 95% CIs and hazard ratios estimated using stratified Cox proportional hazards model.
Results:
Of 1093 patients (ITT population), 982 patients (89.8%) had evaluable IHC assay results; 935/982 (95.2%) had EGFR>0. GC+N arm continuation therapy patients included 228 patients with EGFR>0 and 194 patients (EGFR>0) were GC arm non-progressors. Baseline characteristics were similar except gender (Males: 81% in GC+N vs 91% in GC arm). CT exposure was balanced. Median OS from randomization in GC+N vs GC was 16.1 vs 14.9 months; HR 0.76 (95% CI, 0.61, 0.95). Median PFS in GC+N vs GC was 7.4 vs 6.9 months; HR 0.81 (95% CI, 0.66, 1.00). Figure 1
Conclusion:
In patients with EGFR-expressing tumors, a consistent treatment effect in favor of GC+N continuation maintenance compared to GC non-progressors was observed, similar to ITT population with no unexpected increases in AEs.

P1.01-039 - Does Distance between Chest and Surgery Departments Impact Outcome in Lung Cancer Patients? Results of KBP-2010-CPHG Study (ID 4585)
14:30 - 15:45 | Author(s): O. Molinier
- Abstract
Background:
We studied the impact of the distance between chest and thoracic surgery departments on the outcome of patients followed, for primary lung cancer diagnosed in 2010, in the chest department of 104 French general hospitals participating in KBP-2010-CPHG study.
Methods:
6,083 patients with non-small-cell lung cancer (NSCLC) participated in this study. Univariate and multivariate analyses were performed to identify independent factors for surgery and 1-year mortality. Distance from the usual thoracic surgery department in 2010 was collected for each chest department and included in the model as a 4-class variable: 0 km (same hospital), 1-34 km, 35-79 km, and ≥80 km.
Results:
Overall, 23% of hospitals had a thoracic surgery department; otherwise, mean distance between the hospital and the surgical center was 65 km. 1,157 patients (19%) were operated on; vital status was known for 5,876 patients (97%). Distance was not an independent factor for surgery and for mortality. Independent factors for surgery and mortality are presented in Tables 1 and 2.

P1.07-012 - Efficacy of Immune Checkpoint Inhibitors in Large Cell Neuroendocrine Lung Cancer: Results from a French Retrospective Cohort (ID 4613)
14:30 - 15:45 | Author(s): O. Molinier
- Abstract
Background:
Nivolumab and pembrolizumab, two programmed death (PD)-1 immune-checkpoint–inhibitor antibodies, demonstrated superiority versus standard chemotherapy in second- third line in both squamous and non-squamous lung cancer. Large cell neuroendocrine lung cancer (LCNEC) is a rare tumour often treated as a small cell lung cancer, but there is not a standard of care after a first line progression. Aim of the study was to assess clinical efficacy of PD-1 inhibitors in these patients.
Methods:
We retrospectively reviewed all consecutive LCNEC stage IIIB- IV patients treated with nivolumab or pembrolizumab after platinum-based first line therapy between July 2014 and November 2015 in six French centres. Patients were followed until June 2016. The drugs were given in an early access program or a clinical trial.
Results:
The analysis included 10 patients with advanced stage disease. Eight patients (80%) had a stage IV disease with a median age of 59 [interquartile range (IQR) 55-62] years. The majority were males (n=9; 90%), with good performance status (0-1; 9/90%) and 50% were treated in third line or further. Three patients presented brain metastases. In 5 cases a molecular test was done, finding in one case (20%) a KRAS mutation. Patients received a first line treatment with platinum and etoposide in 8 cases (80%) with a disease control rate of 50%. Nine patients received nivolumab and the PD-L1 status was never performed, while the patient treated with pembrolizumab expressed PD-L1. Patients received a median number of 16 [IQR, 13-18] cycles, 6 showed a partial response (60%), 1 a stable disease (10%). Median PFS was 57 [24-57] weeks. Most of the patients stopped treatment due to disease progression (n=4; 80%), only one for a pulmonary interstitial pneumonia.
Conclusion:
Our findings suggest that the use of immune-checkpoint–inhibitors in LCNEC could be explored in a larger cohort of patients. This treatment could be considered in the scenario of a disease with limited therapeutic strategy.

P2.06-024 - Tedopi vs Standard Treatment as 2nd or 3rd Line in HLA-A2 Positive Advanced NSCLC Patients in a Phase 3, Randomized Trial: ATALANTE-1 (ID 5329)
14:30 - 15:45 | Author(s): O. Molinier
- Abstract
Background:
HLA-A2 is expressed in 40 to 50% of NSCLC patients. TEDOPI is a combination of neoepitopes that generates cytotoxic T lymphocytes responses. It consists of nine HLA-A2 supertype binding epitopes covering five tumor-associated antigens overexpressed in advanced NSCLC and the universal helper pan-DR epitope. In a phase II trial (NCT00104780, Barve et al. JCO 2008), TEDOPI showed a promising median overall survival of 17.3 months with a manageable safety profile in pre-treated HLA-A2 positive patients with advanced NSCLC. ATALANTE-1 (NCT02654587) is a randomized, open-label, phase 3 study comparing the efficacy and safety of TEDOPI with standard treatment in HLA-A2 positive patients with advanced NSCLC, as second- or third-line therapy.

Section not applicable
Results:
Trial design: Patients with advanced NSCLC without EGFR-sensitizing mutations or ALK rearrangements, with progressive disease to first-line platinum-based chemotherapy or second-line immune checkpoint inhibitors (IC) are eligible if they have HLA-A2 positivity and ECOG PS 0-1. Treated and asymptomatic brain metastases are allowed. Patients are randomized 1:1 to receive 1 ml TEDOPI subcutaneously Q3W for 6 cycles, then every two months for the reminder of the year and finally every three months or standard treatment with: 75 mg/m[2] docetaxel Q3W or 500 mg/m[2] pemetrexed Q3W (in non-squamous histology and pemetrexed-naïve patients). In both arms, treatment continues until progression, intolerable toxicity, consent withdrawal, or investigator decision. In TEDOPI arm, treatment may continue beyond initial radiographic disease progression in case of clinical benefit. Randomisation is stratified by histology (squamous vs. non-squamous), initial response to first-line chemotherapy (partial or complete response vs. stabilization or progression), and previous treatment with IC (yes vs. no). Tumor assessment is performed every 6 weeks and adverse events are collected throughout the study and for 60 days and 90 days thereafter and graded per NCI CTCAE v4.0. Archival biopsies samples are required for assessing PD-L1 status (IHC22C3 pharmDx from Dako). Primary endpoint is overall survival; and secondary are progression free survival based on RECIST 1.1 criteria, objective response rate, disease control rate, duration of response, and quality of life measured by QLQ-C30 and QLQ-LC13 global scores. This is a superiority study with a hazard ratio of 0.7391, two-sided alpha 5% and power 80%, after 356 events are observed over 500 patients. The first patient was enrolled on 25th January 2016. Enrolment is ongoing in Europe and the US. Clinical trial identification: NCT02654587 Legal entity responsible for the study & Funding: OSE Immunotherapeutics, France
