MINI25.08 - Systemic Treatment in Advanced Thymic Epithelial Tumors. Insights From a Prospective Cohort of 888 Patients Enrolled in RYTHMIC (ID 1166)
16:45 - 18:15 | Author(s): J. Mazières
- Abstract
Background:
RYTHMIC (Réseau tumeurs THYMiques et Cancer) is the French nationwide network for thymic malignancies. Starting 2012, all patients diagnosed with thymic tumor had to be enrolled, as recommended by the French National Cancer Institute, part of good clinical practice.
Methods:
RYTHMIC prospective database is hosted by the French Thoracic Cancer Intergroup (IFCT), and collects clinical, imaging, treatment, and follow-up data of patients discussed at the reference national multidisciplinary tumor board (MTB). Data cutoff was April 1[st], 2015 for this analysis.
Results:
1089 questions were raised at the MTB about the management of 888 patients with thymic epithelial tumor. Among assessable cases, Masaoka-Koga stage III-IV tumors accounted for 42% of cases; histology was thymoma in 82% of cases, and thymic carcinoma in 18% of cases. First-line treatment of locally advanced disease, and management (diagnosis and treatment) of recurrent disease led to raise 227 (21%), and 234 (21%) questions at the MTB, respectively, 312 (68%) of which were about the modalities of systemic treatment. Figure 2 shows the proposed regimens for primary (A) and exclusive (B) chemotherapy in treatment-naïve patients, and chemotherapy (C) and targeted agents (D) for recurrent tumors. Combination of cisplatin, adriamycin, and cyclophosphamide and carboplatine, paclitaxel were the most frequently proposed regimens as first- and second-line treatment, respectively. Figure 1 Figure 2
Conclusion:
RYTHMIC is an exhaustive registry of thymic malignancies, which provides unique insights in the management of advanced and recurrent tumors with systemic agents. Meanwhile, limited data have been made available in the literature so far, as clinical trials were conducted in small numbers of patients, and existing databases enrolled a majority of surgically resected, early-stage tumors. Through the use of targeted agents, RYTHMIC allows the rapid implementation of new results in clinical practice, while ensuring patients an equal access to therapeutic innovation.

MINI30.03 - Smoking Predicts Sensitivity to PARP Inhibitor, Veliparib, in Advanced NSCLC Patients (ID 1279)
18:30 - 20:00 | Author(s): J. Mazières
- Abstract
- Presentation
Background:
Tobacco-related non-small cell lung cancer (NSCLC) is associated with reduced survival and greater genomic instability. Veliparib (V) is a PARP inhibitor that augments platinum-induced DNA damage in preclinical studies, and a recent Phase 2 trial of advanced NSCLC trended to improved survival (HR 0.80; CI 0.54–1.18) when V was added to carboplatin (C) and paclitaxel (P). Here we report outcomes based on smoking status from this randomized Phase 2 study of CP with either V or placebo in advanced NSCLC.
Methods:
Patients with previously untreated advanced/metastatic NSCLC were randomized 2:1 to CP with either V at 120mg BID or placebo (randomization stratified by histology and smoking history). Cotinine was measured in patients’ plasma samples as an index of recent tobacco use.
Results:
Of 158 patients, 68% were male, and 49% had squamous NSCLC. At study entry, 60% pts were self-reported current smokers, 27% former smokers, and 13% never smoked. There were no significant differences in veliparib pharmacokinetic parameters between cotinine-high and low. Grade 3/4 AEs were elevated in current-smokers treated with VCP vs CP (66% vs. 40%, p=0.026); all-grade AEs and SAEs were similar between the two groups. The most common AEs in current-smokers were neutropenia (41% VCP; 27% CP), alopecia (36%; 33%), and anemia (31%; 40%). Figure 1 A sensitivity analysis of heavy vs light-smokers (≥ vs <39 pack-years, current or former smokers) showed advantage of veliparib in heavy-smokers: median PFS [HR(95% CI)] for VCP/CP was 7.0 vs 3.5 [0.43(0.20–0.94)] for heavy-smokers and 4.4 vs 4.2 [0.97(0.49–1.92)] for light-smokers; median OS was 12.6 vs 8.8 [0.52 (0.27–1.02)] for heavy-smokers and 9.9 vs 8.8 [0.92(0.53–1.61)] for light-smokers. A cotinine sensitivity analysis found that outcomes in cotinine-high were similar to current-smokers: PFS, cotinine-high HR was 0.38 (0.19–0.73) and cotinine-low was 0.97 (0.51–1.87); OS, cotinine-high HR was 0.52 (0.29–0.92) and cotinine-low was 1.07 (0.63–1.81). In univariate analyses assessing the influence of baseline characteristics and treatment on outcomes, smoking status and treatment had a significant interaction (p=0.0301 PFS, p=0.0118 OS). Additionally, multivariate analysis including all factors also identified current smoking as predictive of improved outcomes with VCP.
Conclusion:
Smoking status was a strong predictor of efficacy for veliparib-chemotherapy combination in advanced NSCLC. No differences in pharmacokinetics of V were seen based on plasma cotinine; toxicity of VCP was acceptable regardless of smoking history. A Phase 3 study has been initiated in patients with smoking history (M14-359).

MINI30.07 - Crizotinib in Patients with ROS1 NSCLC. Preliminary Results of the AcSé Trial (ID 2426)
18:30 - 20:00 | Author(s): J. Mazières
- Abstract
- Presentation
Background:
To avoid uncontrolled off-label use and allow for a nationwide safe access to crizotinib (crz) for patients (pts) with an ALK, MET or ROS1 positive (+) tumor, the French National Cancer Institute (INCa) launched the AcSé program, funding both access to tumor molecular diagnosis and an exploratory multi-tumor 2-stage design phase II trial. We report the preliminary results of the ROS1+ NSCLC cohort.
Methods:
ROS1 status was assessed in 28 regional INCa molecular genetic centers by break-apart FISH assays in tumor samples showing an IHC score of ≥1+. Pts with ROS1 rearrangements, progressing after at least one standard treatment (including a platinum-based doublet, unless pts were considered as unfit for chemotherapy) were proposed to receive crz 250 mg BID. Responses were centrally assessed using RECIST v1.1. The objective response rate (ORR) and disease control rate (DCR) were assessed every 8 weeks.
Results:
From Aug. 5, 2013 to Mar. 1, 2015, 39 pts with ROS1+ NSCLC were enrolled. 37 pts had received crz, leading to 37 pts with clinical information. Median age: 62 years (range 33–81), 70% females, 95% non-squamous histology, and 94% metastatic disease at study entry. Median number of prior treatments: 2 (range 1 –7). Twenty four pts were still on treatment at the cut-off date, 13 have stopped crz (8 PD, 3 adverse events (AEs), 2 deaths). Among the 27 pts evaluable for response at 8 weeks, we observed 16 PR, 7 SD and 4 PD, leading to ORR=59% [95% CI:39-78], and DCR=85% [66-96]. DCR at 6 months was 57% (disease control was achieved in 12/21 evaluable pts). Crz was well tolerated with only 4 grade ≥3 (1 AE + 3 SAEs) and 9 grade 1-2 SAEs. Most common AEs, mainly grade 1, were visual disorders (54% of pts), peripheral edema (51%), diarrhea (48%), nausea (46%), and elevated transaminases (43%).
Conclusion:
Crz was well tolerated and achieved a robust treatment response rate in ROS1+ NSCLC. These results underline the interest of integrating ROS1 in biomarkers routine screening. Survival data and duration of response will be presented.

ORAL02.03 - Longer-Term Follow-Up of a Phase 2 Study (CheckMate 063) of Nivolumab in Patients with Advanced, Refractory Squamous Non-Small Cell Lung Cancer (ID 828)
10:45 - 12:15 | Author(s): J. Mazières
- Abstract
- Presentation
Background:
Patients with advanced, refractory squamous (SQ) non-small cell lung cancer (NSCLC) have historically poor outcomes and limited treatment options. Nivolumab (NIVO), a fully human IgG4 programmed death-1 (PD-1) immune checkpoint inhibitor antibody, has activity across NSCLC histologies and is FDA-approved for treatment of metastatic SQ NSCLC with progression on or after platinum-based chemotherapy. We report efficacy, safety, and biomarker analyses from a phase 2, single-arm study of NIVO in patients with SQ NSCLC who progressed during/after prior platinum-based doublet chemotherapy and ≥1 additional systemic regimen.
Methods:
Patients (N=117) received NIVO 3 mg/kg every 2 weeks until progressive disease (PD)/unacceptable toxicity; treatment beyond PD was permitted per protocol. The primary endpoint was independent radiology review committee (IRC)-assessed objective response rate (ORR), per RECIST v1.1. Additional objectives included investigator-assessed ORR, progression-free survival (PFS), overall survival (OS), safety, ORR by patient subgroups, efficacy by tumor PD-L1 expression (PD-L1[+]: ≥5% tumor cells expressing PD-L1), and blood-based biomarker analyses (measurement of circulating microRNA and cytokines).
Results:
IRC-assessed ORR was 15% (95% CI: 9, 22), with a minimum of 11 months follow-up. Median duration of response was not reached (range, 2+–12+ months); 76% (13/17) of patients had ongoing responses. Objective responses were observed across patient subgroups and regardless of PD-L1 expression (Table). Four of 22 patients treated beyond PD demonstrated a non-conventional pattern of benefit (ie, persistent reduction in target lesions in the presence of new lesions, regression following initial progression, or no further progression for ≥2 tumor assessments); OS for these patients was 6.6, 11.6+, 12.9+, and 13.5+ months. The 1-year OS rate was 41% (95% CI: 32, 50) and median OS was 8.2 months (95% CI: 6.1, 10.9). The 1-year PFS rate was 20% (95% CI: 13, 29); median PFS was 1.9 months (95% CI: 1.8, 3.2). Peripheral increases in serum IFN-γ-stimulated cytokines, including CXCL9 and CXCL10, were observed, and preliminary microRNA analyses identified altered gene expression following NIVO treatment. Grade 3–4 treatment-related adverse events occurred in 17% of patients, including fatigue (4%), diarrhea (3%), and pneumonitis (3%). Pneumonitis was manageable with corticosteroids; median time to resolution was 3.4 weeks (range, 0.7–13.4). Two treatment-related deaths (1 hypoxic pneumonia, 1 ischemic stroke) occurred in patients with multiple comorbidities and concurrent PD. Figure 1
Conclusion:
NIVO demonstrated clinically meaningful efficacy and an acceptable safety profile in patients with advanced, refractory SQ NSCLC. Updated 18-month OS, safety, and biomarker analyses will be presented.

ORAL11.01 - Bevacizumab 15mg/kg Plus Cisplatin-Pemetrexed (CP) vs CP in Malignant Pleural Mesothelioma (MPM): IFCT-GFPC-0701 MAPS Randomized Phase 3 Trial (ID 2142)
10:45 - 12:15 | Author(s): J. Mazières
- Abstract
Background:
MPM median overall survival (OS) did not exceed 13 months with pemetrexed-platinum doublet, with virtually no surviving patients at 5 years. Vascular endothelial growth factor is a potent mitogen for MPM cells.
Methods:
In this French multicenter randomized phase 3 trial, eligible patients had unresectable, histologically proved MPM, age < 76, no prior chemo, PS 0-2, no thrombosis, nor bleeding. Randomized patients (1:1) received pem 500 mg/m2, CDDP 75 mg/m2 at D1, with (arm B) or without bevacizumab (arm A), 15 mg/kg Q21D, for 6 cycles. Arm B non-progressive patients received bevacizumab maintenance therapy until progression or toxicity. Primary endpoint was OS. 445 patients were to be randomized, and 385 events observed, to show a significant OS improvement, with 80% statistical power, 5% a-risk.
Results:
From Feb. 2008 to Jan. 2014, 448 patients were included in 73 centers. Males: 75.4%, median age: 65.7 years (range 34.7-75.9), PS 0-1: 96.7%. The IDMC recommended a second interim analysis after 85% of events. On 01-Jan-2015, the duration since last news was < 30 days in 105 out of 106 still living patients. Overall survival was significantly longer in the experimental arm (median: 18.8 months, 95%CI[15.9-22.6] vs. 16.1 months, 95%CI[14.0-17.9] for the reference arm, (adj.HR = 0.76, 95%CI[0.61; 0.94], p = 0.012). With only 46/448 non-progressive patients at the date of analysis, median PFS was 9.6 months, 95%CI[8.5-10.6] in bevacizumab arm vs. 7.5 months, 95%CI[6.8-8.1] (adj.HR = 0.62, 95%CI[0.50-0.75], p < 0.0001). G3-4 hematological toxicities did not significantly differ in the two arms (49.5% vs. 47.3%). Significantly more G3 proteinuria (0.0 vs. 3.1%), G3 hypertension (0.0 vs. 23%), G3-4 arterial thrombotic events (0.0 vs. 2.7%) were observed in bevacizumab arm. QOL and exploratory biomarkers studies will be also presented at time of the meeting.
Conclusion:
Bevacizumab addition to pemetrexed/cis-platin provides a significantly longer survival in pts with MPM, with acceptable toxicity, making this triplet a new treatment paradigm.

ORAL33.01 - Crizotinib Outcome and Post-Progression Management in ALK+ NSCLC: IFCT-1302 CLINALK (ID 1355)
16:45 - 18:15 | Author(s): J. Mazières
- Abstract
- Presentation
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.

P3.04-053 - SPECTAlung: Screening Patients with Thoracic Tumors for Efficient Clinical Trial Access (ID 1386)
09:30 - 17:00 | Author(s): J. Mazières
- Abstract
Background:
The identification of molecular alteration and its targeting has completely changed the treatment and prognosis of lung cancer. However, designing and implementing clinical trials in small subsets of patients with a particular molecular alteration is challenging because of lack of uniform screening program. Across Europe, screening for molecular alterations is center or country dependent and, generally limited to a small subset of genes. SPECTAlung is the first European standardized, quality-assured molecular screening program of the European Organization for the Research and Treatment of Cancer (EORTC) in collaboration with the European Thoracic Oncology Platform (ETOP) to facilitate clinical trial access for patients with thoracic tumors. It is expected to test 500 to 1000 patients each year with the overall goal of offering patients clinical trials with targeted agents.
Methods:
Patients sign the informed consent for their tumor tissue to be collected, centralized and processed according to defined international quality control standards at Gustave Roussy Biobank (Villejuif, France). Next Generation Sequencing (NGS) is performed at Sanger Institute (Cambridge, UK) where a panel of about 360 genes is analyzed for mutation, rearrangements and gene copy number. Eligible patients will be those having a pathological diagnosis of any thoracic tumor (lung cancer, malignant pleural mesothelioma and thymic malignancies) at any stage of disease, availability of tumor tissue, age at least 18 years, PS 0-2, life expectancy > 3 months, no active malignancy in the 5 years before study entry and absence of any exclusion criteria that may prevent inclusion into clinical trials. A molecular report will be released to the investigator highlighting identified molecular alterations and also the trials for which the patients might be eligible. The study has been submitted to ethical committees of 15 selected highly specialized and qualified thoracic centres in 12 countries in Europe. EORTC and ETOP will promote the implementation of clinical trials in molecularly selected groups of patients at the SPECTAlung centers. SPECTAlung offers innovative and attractive models of collaboration with commercial and research organizations, by improving patient access to novel therapeutic clinical trial and support the development of personalized medicine. Clinical trial registry number NCT02214134.
