23P - Immunosenescence (iSenescence) correlates with progression (PD) to PD-(L)1 inhibitors (IO) and not to platinum-chemotherapy (PCT) in advanced non-small cell lung cancer (aNSCLC) patients (pts) (ID 599)
12:30 - 13:00 | Author(s): Benjamin Besse
- Abstract
Background
iSenescence is a remodeling of immune functions with a multifactorial etiology (i.e. aging, chronic inflammation, cancer). Although the absence of CD28 and the expression of CD57 and KLRG1 on circulating T-lymphocytes are hallmarks of iSenescence, the characterization of such phenotype in aNSCLC pts and the correlation with clinical characteristics and benefit from IO or PCT are currently unknown.
a9ded1e5ce5d75814730bb4caaf49419 Methods
A senescent immune phenotype (SIP) defined as % of circulating CD8+CD28-CD57+KLRG1+ T-lymphocytes was assessed by flow cytometry (FC) on fresh blood from aNSCLC pts treated with IO or PCT in a single institution. A log-rank maximization method was used to identify a SIP cut-off level and dichotomize pts accordingly. The objective was to correlate SIP with clinical characteristics and RECIST response by univariate logistic regression analysis.
20c51b5f4e9aeb5334c90ff072e6f928 Results
37 aNSCLC pts were evaluable for SIP before IO: 32% ≥ 65 years, 91% non-squamous, 43% KRAS mutated, 51% with PD-L1 expression ≥1%, 8% chemotherapy naïve. 43% had PD, 41% stability (SD), 16% partial response (PR). Median PFS and OS were 2.7 (95% CI 1.8; 7.3) and 13 (95% CI 4.8-NR) months, respectively, median follow-up was 9.3 (95% CI 6.2-14.9) months. SIP (% CD28-CD57+KLRG1+) median value on circulating CD8+ lymphocytes was 12.2% (min 1.7%, max 56.1%). 32% of pts had >20.47% CD8+ lymphocytes with a CD28-CD57+KLRG1+ phenotype, being classified SIP+. SIP status did not significantly correlate with age, pts’ characteristics or CT exposure. 2 (17%) of 12 SIP+ had PR/SD (DCR), vs 19 (76%) of 25 SIP- pts (p = 0.001); median PFS was significantly lower in SIP+ (1.5 months 95% CI 1;2.2) vs SIP- pts (7.4 months 95% CI 5.5, 9.3) (p = 0.001). Among 61 aNSCLC pts treated with 1st line PCT, 18% had PD, 43% SD, 39% PR. SIP median value on circulating CD8+ lymphocytes was 17.9% (min 0.89%, max 66.1%), 43% of pts were SIP+. SIP did not significantly correlate with DCR (OR: 0.82, 95% CI 0.22-3.13, p = 0.82) upon PCT.
fd69c5cf902969e6fb71d043085ddee6 Conclusions
iSenescence, monitored by FC measurement of 3 surface molecules on circulating CD8 + lymphocytes, is observed in 32% and 43% of aNSCLC pts before IO or PCT, respectively. SIP correlated with lower DCR upon IO and not PCT.

113O - Entrectinib in NTRK fusion-positive non-small cell lung cancer (NSCLC): Integrated analysis of patients (pts) enrolled in STARTRK-2, STARTRK-1 and ALKA-372-001 (ID 540)
08:00 - 08:50 | Author(s): Benjamin Besse
- Abstract
- Presentation
Background
Neurotrophic receptor tyrosine kinase (NTRK) gene fusions lead to the expression of chimeric TRK proteins with constitutively activated kinase function, conferring oncogenic potential across several tumour types. Entrectinib is a CNS-active, potent inhibitor of TRKA/B/C and ROS1. We present integrated efficacy and safety data for entrectinib in NTRK fusion-positive (NTRK-FP) solid tumours focusing on pts with NSCLC.
a9ded1e5ce5d75814730bb4caaf49419 Methods
Pts with locally advanced/metastatic NTRK-FP tumours (with or without baseline CNS disease) confirmed by nucleic acid-based methods, enrolled in global (>150 sites, 15 countries) phase 1/2 entrectinib trials (ALKA-372-001 [EudraCT 2012-000148-88], STARTRK-1 [NCT02097810], STARTRK-2 [NCT02568267]) were included. Disease burden was assessed per BICR using RECIST v1.1, after cycle 1 (4 wks) then every 8 wks. Primary endpoints: ORR, DOR by BICR. Secondary endpoints: PFS, OS, and safety.
20c51b5f4e9aeb5334c90ff072e6f928 Results
Outcomes in the total efficacy-evaluable population (n = 54; 10 tumour types, >19 histopathologies) are shown in the table; responses were seen in all tumour types, median PFS 11.2 mo. In the cohort of pts with NTRK-FP NSCLC (n = 10), BICR ORR was 70% (7/10). In NSCLC pts with CNS disease per investigator at baseline (n = 6), 4 had an intracranial response (2 complete, 2 partial); 1 had stable disease and 1 was not evaluable. In the safety population (68 pts with NTRK-FP solid tumors who received at least 1 dose of entrectinib), most treatment-related adverse events (TRAEs) were grade 1–2; grade 3: 32.4%, grade 4: 2.9%; no grade 5 TRAEs. TRAEs resulted in discontinuation in 4.4% and dose reduction in 39.7% of pts.
fd69c5cf902969e6fb71d043085ddee6 Conclusions
In this integrated analysis of global multicentre clinical trials, entrectinib was well tolerated and induced clinically meaningful, durable systemic and intracranial responses in pts with NTRK-FP solid tumours, including those with NSCLC. (Table).

110O - Plasma circulating tumor DNA analysis (ctDNA) for molecular alteration detection in advanced non-small cell lung cancer (NSCLC) patients (pts) with isolated central nervous system (CNS) metastases (mts) (ID 310)
09:00 - 10:30 | Author(s): Benjamin Besse
- Abstract
- Presentation
Background
In advanced NSCLC, ctDNA is an emerging tool in molecular profile testing at diagnosis and at resistance to targeted therapies. However, for CNS limited mts, ctDNA might have a reduced accuracy because of low concentrations. Aim: to assess feasibility of ctDNA in NSCLC with isolated CNS disease/progression (PD) (iCNS).
a9ded1e5ce5d75814730bb4caaf49419 Methods
This is a retrospective analysis of consecutive advanced NSCLC pts treated at Gustave Roussy from 01.2016 to 06.2018 included in 2 prospective studies (CEC-CTC, MSN). Included: any molecular tissue alteration at baseline (EGFR, ALK, BRAF, KRAS, HER2, ROS1, MET, TP53), CNS disease and ≥1 ctDNA sample at diagnosis/PD. CtDNA was performed by next generation sequencing (NGS- InVisionSeq™-Lung). Clinical/molecular/imaging data were collected. CtDNA in iCNS group were compared to systemic PD group (with CNS PD or stable disease, S-CNS). ctDNA was defined as positive if ≥ 1 mutation in the NGS panel.
20c51b5f4e9aeb5334c90ff072e6f928 Results
422/959 screened pts had ≥1 ctDNA sample. 183/422 pts had CNS disease. 58/182 pts had ctDNA sample at time of CNS disease and 66 samples were eligible for inclusion: 21 iCNS and 45 S-CNS (≥1 sample/patient as ≥ 1 PD). In iCNS and S-CNS, pts characteristics were: median age 55 vs 59 years, female gender 94% vs 59%, adenocarcinoma histology 100% vs 93%, smoking history 35% vs 44%, median mts sites at diagnosis 1 vs 2. Prevalence of EGFR mutation at diagnosis was 76 and 61%, ALK rearrangement 18 and 10%, KRAS 6 and 5% in iCNS and in S-CNS, respectively. HER2, TP53, BRAF and MET alterations were present only in S-CNS group (12%, 10%, 5% and 2%). CtDNA was positive in 38% in iCNS vs. 98% in S-CNS groups (Fisher test, p < 0.0001) (Table).
fd69c5cf902969e6fb71d043085ddee6 Conclusions
In NSCLC pts with isolated CNS involvement, genomic alterations assessed by ctDNA in plasma had a low detection rate. (Table).

21O - EPAC-Lung: Pooled analysis of circulating tumor cells in advanced non-small cell lung cancer (ID 434)
09:00 - 10:30 | Author(s): Benjamin Besse
- Abstract
- Presentation
Background
We assessed the clinical validity of circulating tumor cell (CTC) quantification for prognostication of patients with advanced non-small cell lung cancer (NSCLC) by undertaking a European pooled analysis of individual patient data. This is the largest study of its kind and the first to examine between-centre heterogeneity of CTC identification in NSCLC.
a9ded1e5ce5d75814730bb4caaf49419 Methods
Nine European NSCLC CTC centers were asked to provide reported/unreported anonymised data for patients with advanced NSCLC who participated in CellSearch CTC studies from January 2003 - March 2017. We used Cox regression models, stratified by centre, to establish the association between CTC count and survival. We assessed the added value of CTCs to prognostic clinico-pathological models using likelihood ratio (LR) statistics and c-indices.
20c51b5f4e9aeb5334c90ff072e6f928 Results
Seven out of nine eligible centers provided data for 550 eligible patients, including 209 patients whose prognostic information was previously unpublished. CTC counts of ≥ 2 and ≥5 per 7·5 mL were associated with reduced progression-free survival (≥2 CTCs: HR 1.72, p < 0·001; ≥5 CTCs: HR 2.21, p < 0·001) and overall survival (≥2 CTCs: HR 2·18, p < 0·001; ≥5 CTCs: HR 2·75, p < 0·001), respectively. Survival prediction was significantly improved by addition of baseline CTC count to LR clinico-pathological models (log-transformed CTCs p < 0·0001; ≥2 CTCs p < 0·0001; ≥5 CTCs p < 0·0001), while more moderate improvements were observed with the use of c-index models. There was minor evidence of between-center heterogeneity in the effect on PFS, but not OS.No difference in CTC profile was observed between key NSCLC molecular subsets such as EGFR, ALK, and KRAS.
fd69c5cf902969e6fb71d043085ddee6 Conclusions
These data confirm CTCs as an independent prognostic indicator of progression-free survival and overall survival in advanced NSCLC. CTC count improves prognostication when added to full clinico-pathological predictive models. ≥2 CTCs is an appropriate cutoff to move towards establishing clinical utility.
