Abstract
PURPOSE HER2 exon 20 insertions and point mutations are oncogenic drivers found in 1%-2% of patients with non-small-cell lung cancer (NSCLC). No targeted therapy is approved for this subset of patients. We prospectively evaluated the effectiveness of the combination of two antibodies against human epidermal growth factor 2 (HER2 [HER2] trastuzumab and pertuzumab with docetaxel; trastuzumab and pertuzumab) and docetaxel. METHODS The IFCT 1703-R2D2 trial is a multicenter, nonrandomized phase II study. Patients with HER2-mutated, advanced NSCLC who progressed after ≥ 1 platinum-based treatment were enrolled. Patients received pertuzumab at a loading dose of 840 mg and 420 mg thereafter; trastuzumab at an 8 mg/kg loading dose and 6 mg/kg thereafter; and docetaxel at a dose of 75 mg/m2 every 3 weeks. The primary outcome was the objective response rate (ORR). Other end points included the duration of response, progression-free survival, and safety (NCT03845270). RESULTS Forty-five patients were enrolled and treated. The median age was 64.5 years (range, 31-84 years), 35% were smokers, 72% were females, 15% had an Eastern Cooperative Oncology Group performance status of 2, and 30% had brain metastases. The objective response rate was 29% (n = 13), and 58% had stable disease (n = 26). The median progression-free survival was 6.8 months (95% CI, 4.0 to 8.5). The median duration of response in patients with a confirmed response (n = 13) was 11 months (95% CI, 2.9 to 14.9). Grade 3/4 treatment-related adverse events were observed in 64% of the patients. No patient discontinued treatment because of toxicity. The most frequent grade ≥ 3 treatment-related adverse events were neutropenia (33%), diarrhea (13%), and anemia (9%). CONCLUSION Triple therapy with trastuzumab, pertuzumab, and docetaxel is feasible and effective for HER2-mutated pretreated advanced NSCLC. These results highlight the effectiveness of the HER2 antibody-based strategy, which should be considered for these patients.

Abstract
INTRODUCTION The third-generation tyrosine kinase inhibitor (TKI) osimertinib is recommended as a first-line treatment in advanced non-small cell lung cancer harboring an activating mutation of Epidermal Growth Factor Receptor (EGFR). Adverse pulmonary events related to osimertinib exposure have been reported, primarily in Japanese patients. They rarely occur in the Caucasian population. OBSERVATION Herein we report two clinical cases of osimertinib-induced lung toxicities in patients diagnosed with advanced lung adenocarcinoma harboring an EGFR mutation. In the first case, interstitial pneumonia was asymptomatic and evolved favorably after osimertinib discontinuation. The second patient presented a more extensive form of lung injuries and despite systemic corticosteroid therapy, the evolution was fatal. CONCLUSION Osimertinib-related lung toxicities remain exceptional. While most forms are mild, consideration of TKI treatment discontinuation may be necessitated. Introduction of another TKI or rechallenge with osimertinib might be considered along with corticosteroid therapy if necessary. Diffuse alveolar damage is a pejorative prognostic factor.

Abstract
Background Idiopathic pulmonary fibrosis is a disease with a poor prognosis and has been associated with increased lung cancer incidence. Case presentation We report the case of a Caucasian 75-year-old woman, a former smoker, hospitalized for breathlessness with a chest computed tomography scan showing an interstitial lung disease. A surgical lung biopsy was performed, confirming a pattern of usual interstitial pneumonia but also numerous disseminated foci of well-differentiated focally invasive squamous cell carcinoma without hypermetabolic lung nodule, mass, or enlarged lymph node visualized on chest computed tomography or positron emission tomography scan. Nintedanib was started for its antifibrotic and antitumor properties, without any other antineoplastic treatment. Three years after initiation of nintedanib, clinical, functional, and computed tomography scan evaluations were stable, and there was no evidence for evolution of the squamous cell carcinoma. Conclusions Data are scarce regarding the benefit of nintedanib in patients with idiopathic pulmonary fibrosis-associated lung cancer, and it is unclear whether nintedanib could have a preventive role in lung carcinogenesis in idiopathic pulmonary fibrosis patients. This experience could help the scientific community in case of similar incidental findings.

Abstract
BackgroundMalignant pleural mesothelioma (MPM) is an aggressive malignancy without curative treatment. Standard of care (SOC) include pemetrexed/cisplatin and nivolumab/ipilimumab with median overall survival in unresectable disease of 12.1 months and 18.1 months respectively.1 2 ONCOS-102 is a granulocyte-macrophage colony stimulating factor (GM-CSF) expressing oncolytic adenovirus (Ad5/3-D24-GMCSF) with a unique ability to both prime and boost immune responses. The aim of the study was to assess efficacy and safety of ONCOS-102 in combination with SOC chemotherapy in 1st and 2nd line unresectable MPM.MethodsTwenty patients (experimental arm) were allocated to receive ONCOS-102 given intratumorally under CT or US guidance at a dose of 3 x 1011 VP on Day 1, 4, 8, 36, 78 and 120 plus six cycles of SOC starting on Day 22. Eleven patients (control group) received SOC. Imaging was done at baseline, Day 43–64 and 127–148 with regular monitoring of blood and biopsy based immune markers. Primary objective was safety and tolerability. Secondary objectives were ORR, PFS and OS as well as immunological activation. An analysis of 24 month survival data compared randomised only patients excluding six patients in the single-arm safety lead-in.Results24-month survival rate for 1st line pts was 50% in the experimental group and 0% in the control group with mOS of 25.0 months and 13.5 months respectively (N.S). Based on censoring, mOS in the experimental group will be within 21.9 – 25.0 months range. mOS across both 1st and 2nd line was 19.3 and 18.3 months for experimental and control patients (N.S). mPFS was 9.8 months in the experimental group and 7.6 in the control group (N.S.).ConclusionsThe survival rate of patients receiving ONCOS-102 in combination with SOC was seen to be numerically higher than previously reported for SOC or nivolumab/ipilimumab. Improved survival was associated with ONCOS-102 induced immune activation with a favourable TME modulation providing scientific rationale for combination with check point inhibition.Trial RegistrationClinicalTrials.gov NCT02879669ReferencesVogelzang, et al, Phase III study of pemetrexed in combination with cisplatin versus cisplatin alone in patients with malignant pleural mesothelioma.

Abstract
Introduction The optimal management of large cell neuroendocrine cancer of the lung (LCNEC) is unclear, and data regarding anti–programmed cell death protein 1 (PD-1) antibodies are scarce. This study reports the clinical efficacy of a PD-1 inhibitor in patients with advanced LCNEC. Methods All patients with stage III to IV LCNEC treated with at least one previous cycle of chemotherapy between January 1, 2015 and December 31, 2018 were reviewed retrospectively. Patients were divided into two groups depending on their exposure to nivolumab as second-line treatment or beyond. The primary objective was to assess nivolumab’s efficacy. Results A total of 51 patients with advanced LCNEC from eight centers were analyzed, including 17 who received nivolumab. The PD-1 inhibitor was used as second-line treatment in 77% of cases, with a median number of eight doses (range: 1–62). After nivolumab treatment, the median overall survival was 12.1 months (95% confidence interval [CI]: 7.10–14.20). The objective response rate was 29.4% (95% CI: 10.3–56.0), and median progression-free survival was 3.9 months (95% CI: 1.68–7.17). The programmed death-ligand 1 status was unknown. There was no difference in the efficacy of first-line chemotherapy; the objective response rate was 23.5% (n = four of 17) in the nivolumab group versus 32.4% (n = 11 of 34) in the conventional treatment group, and progression-free survival was 3.5 months (95% CI: 1.7–4.4) versus 2.1 months (95% CI: 1.4–4.2), respectively. Conclusions In a real-world setting, nivolumab seems to be an effective second-line treatment in patients with advanced LCNEC. Large prospective studies in this setting are still required.

Abstract
In the management of cystic fibrosis, treatments against Staphylococcus aureus and Haemophilus influenzae such as amoxicillin or cotrimoxazole have to be prescribed and the antibiotherapy's efficacy may be linked to the concentration that reaches the infected site. As cystic fibrosis patients present disturbed pharmacokinetics parameters, drug monitoring would be relevant to assess the lung distribution of antibiotics and to optimize dosing regimens. In this context, the aim of the study was to develop and validate HPLC-based methods for the determination of both antibiotics in bronchial sputum from cystic fibrosis patients, in order to assess the distribution of the drugs into the lungs. Plasma proteins were precipitated by acetonitrile and amoxicillin concentrations in sputum were determined by HPLC coupled with tandem-mass spectrometry. Following liquid extraction with ethyl acetate, cotrimoxazole was quantified by HPLC using ultraviolet detection. Both methods were rapid, specific, accurate and reproducible. The method was applied to patient samples. In three treated patients, concentrations of amoxicillin in sputum were similar and below the lower limit of quantification (0.1 μg/g) and in six patients, sputum concentrations up to 11.1 and 6.4 μg/g were measured for sulfamethoxazole and trimethoprim, respectively.

Abstract
Lung cancer prognosis has improved in the last decade, including in patients with brain metastasis. However, few of these patients who receive corticosteroids have a primary prophylaxis for Pneumocystis jirovecii pneumonia (PJP). We report the case of an 80-year-old man diagnosed with non-small cell lung cancer and concomitant symptomatic brain metastases, treated with 50 mg/day of prednisolone without any prophylaxis, who presented an acute PJP. After 72 hours of unsuccessful treatment of PJP, the patient died. In our review of this case and the existing literature, we emphasise the importance of a wide use of prophylaxis for PJP, especially in advanced lung cancer treated with corticosteroid therapy. We discuss this issue and report current evidence for primary prophylaxis by trimethoprim–sulfamethoxazole.

Abstract
Pembrolizumab plus chemotherapy is currently used in the first-line treatment of advanced non-small-cell lung cancer without EGFR mutations or ALK rearrangements, regardless of PD-L1 expression status. A study comparing chemotherapy plus pembrolizumab versus pembrolizumab alone has never been performed in patients with PD-L1 ≥50%. The aim of this trial is to perform such a comparison as first-line treatment in patients not eligible for locally advanced treatment who have expression of PD-L1 on ≥50% of tumor cells. The expected results are a reduction in the risk of early progression. A higher objective tumor response is also expected with the combination of chemotherapy and pembrolizumab compared with pembrolizumab alone. The study will allow a direct comparison of the proportion of patients who derive long-term benefit from the treatment. Clinical trial number: EudraCT (2020-002626-86); ClinicalTrials.gov (NCT04547504).

Abstract
9015 Background: Human epidermal growth factor receptor 2 ( HER2) exon 20 insertions and mutations are oncogenic drivers found in 1-2% of NSCLC. However, there are no approved therapies for these patients. Many studies suggest that the use of HER2 inhibitors developed for breast cancer patients might be of interest in this setting. The aim of this trial was to prospectively evaluate the interest of a combination of two antibodies against HER2 (trastuzumab and pertuzumab) with docetaxel. Methods: IFCT-1703 R2D2 trial is a multicenter, non-randomized phase 2 study with a two-stage design, a power of 90% and an alpha risk at 5% (one-sided). HER2 mutational status was assessed locally in certified molecular genetic centers. Main other inclusion criteria were advanced NSCLC, progression after ≥ 1 platinum-based chemotherapy, asymptomatic brain metastases, left ventricular ejection fraction (LVEF) ≥ 50%, and PS 0-2. Patients were treated every 3 weeks with pertuzumab at a loading dose of 840 mg, and 420 mg thereafter; plus trastuzumab at a loading dose of 8 mg/kg and 6 mg/kg thereafter; and docetaxel at 75 mg/m². Treatment was given until toxicity or disease progression. The primary outcome was overall response rate (ORR). Other endpoints included duration of response, progression-free survival and safety. NCT number: NCT03845270. Results: From May 2019 to October 2020, 45 patients were enrolled in 17 centers and received study treatment. Median age was 64.5 years (range 31–84), 72% females, 35% smokers, 100% non-squamous histology and 15% with ECOG PS 2. 31.1% patients had brain metastases. PD-L1 was expressed ≥ 1% and ≥ 50% in 36% and 7% of the patients, respectively. No other oncogene driver was found associated with HER2 exon 20 mutation. With a median follow-up of 12 months, 44 (98%) patients were evaluable for the primary endpoint. Overall response rate was 29% (n = 13), stable disease 56% (n = 26). Median PFS was 6.8 months (95% CI[4.0-8.5]). Median duration of treatment in patients with confirmed response (n = 13) was 10 months (95% CI[2.7-14.9]). At the time of data cut-off, 15 patients (33%) were still under treatment. Grade 3/4 treatment-related adverse events (AEs) were observed in 64% of patients. No patient experienced treatment discontinuation because of toxicity. One sudden death was possibly related to treatment. Most frequent grade ≥ 3 AEs were neutropenia (33%), diarrhea (13%) and anaemia (9%). Grade 1/2 dyspnea was observed in 3 (6.7%) patients. No ILD were reported. Variation LVEF was -1.72% on average (min: -18 %; max: 10 %). Conclusions: The triplet trastuzumab, pertuzumab and docetaxel is feasible and active in HER2 pretreated advanced NSCLC. These results confirm the activity of HER2 antibodies-based strategy which should be considered in these patients. Clinical trial information: NCT03845270.

Abstract
9091 Background: To determine real-world outcomes with first line pembrolizumab monotherapy, for aNSCLC with PD-L1 TPS ≥50%. Methods: Bispective, national and multicentric study including consecutively aNSCLC patients who initiated first-line pembrolizumab monotherapy from May 5, 2017 (marketing authorization of pembrolizumab monotherapy in France) to Nov 22, 2019 (marketing authorization of pembrolizumab-chemotherapy for non-squamous aNSCLC). Data were collected on medical charts. Responses were locally assessed according to RECIST v1.1; overall survival (OS) and real-world progression-free survival (rwPFS) were assessed by Kaplan-Meier method. Results: 845 patients (pts) were included by 33 centres: 67.8% were men, PS 0/1/≥2: 25.5%/46.9%/27.6%, active/former/nonsmokers: 39.1%/51.7%/6.4%, adenocarcinoma: 70.8%; stage IV at diagnosis: 91.6%; median number of metastatic sites at baseline: 2±1 (brain (20.8%), liver (13.9%) and bone (35%)); KRAS mutated: 27.7%, PDL1 TPS > 75%: 53.7% At the cut off date (31 December 2020), on the 783/845 (92.7%) evaluable pts, CR, PR, disease stabilization and progression were reported on 4.7%, 42.6%, 24.1% and 28.6% of cases, respectively; 588 (69.6%) pts had discontinued pembrolizumab, 390 (66.4%) had a first disease progression; 320/390 (82.1%) received a second line treatment, mainly platinum-based chemotherapy (90.6%). With a median follow up of 25,8 [95%CI: 24,8-26,7] months, median rwPFS and median OS were 8,2 [95%CI: 6,9-9,5] and 22,6 [95%CI: 18,5-27,4] months, respectively; 6, 12, 18-months survival rates were 76,8%, 64,8% and 54,3%. 835 adverse events were reported in 48% of the patients, grade ≥3 in 13.8% of cases, mainly asthenia, colitis, pneumonitis. For evaluable patients receiving a platinum-based doublet in second line (266/290, 89%), CR, PR, disease stabilization and progression were reported on 1.9%, 41%, 35.3% and 21.8% of cases, respectively. Uni and multivariate analysis of factors related to OS will be presented at the congress. Conclusions: Despite a less stringent selection of patients, pembrolizumab as a single agent achieves similar tumor shrinkage, rwPFS and OS than those of pivotal clinical trials.

Abstract
OBJECTIVES The duration of stereotactic body radiotherapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) may affect patient outcomes. We aimed to determine the impact of a continuous versus discontinuous SBRT schedule on local control (LC) and overall survival (OS) in NSCLC patients. MATERIALS AND METHODS Consecutive NSCLC stage I patients (475) treated with SBRT in four centers were retrospectively analyzed. The delivered dose ranged from 48 to 75 Gy in 3-10 fractions. Based on the ratio between the treatment duration (TD) and number of fractions (n), patients were divided into two groups: continuous schedule (CS) (TD ≤ 1.6n; 239 patients) and discontinuous schedule (DS) (TD > 1.6n; 236 patients). LC and OS were compared using Cox regression analyses after propensity score matching (216 pairs). RESULTS The median follow-up period was 41 months. Multivariate analysis showed that the DS (hazard ratio (HR): 0.42; 95 % confidence interval (CI): 0.22-0.78) and number of fractions (HR: 1.24; 95 % CI: 1.07-1.43) were significantly associated with LC. The DS (HR: 0.67; 95 % CI: 0.51-0.89), age (HR: 1.02; 95 % CI: 1-1.03), WHO performance status (HR: 2.27; 95 % CI: 1.39-3.7), and T stage (HR: 1.4; 95 % CI: 1.03-1.87) were significantly associated with OS. The 3-year LC and OS were 92 % and 64 % and 81 % and 53 % for DS and CS treatments, respectively (p < 0.01). Cox analysis confirmed that the discontinuous SBRT schedule significantly increased LC and OS. CONCLUSION DS is associated with significantly improved LC and OS in early-stage NSCLC patients treated with SBRT.

[PMID: 34016488 DOI: 10.1016/j.lungcan.2021.05.013] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 04/27/2021] [Accepted: 05/09/2021] [Indexed: 12/22/2022]
Abstract
INTRODUCTION HIV is an exclusion criterion for most lung cancer (LC) trials, however LC is the most common non-AIDS-defined malignancy in people living with HIV (PLHIV), poorer prognosis than the general population. Circulating tumor DNA (ctDNA) was a prognostic marker in LC patients from the general population. This study assessed ctDNA's prognostic value in PLHIV from a dedicated phase II trial. METHODS Overall, 61 PLHIV with advanced non-squamous non-small-cell lung cancer (NSCLC) participated in the IFCT Phase II trial evaluating first-line four-cycle carboplatin (Ca) AUC5 pemetrexed (P) 500 mg/m2 induction therapy every 3 weeks, followed by P maintenance therapy. Blood samples collected before treatment were analyzed to detect ctDNA using ultra-deep targeted next-generation-sequencing (NGS). RESULTS Appropriate samples were available from 55 PLVIH and analyzed for ctDNA detection. Including 42 males (76.4 %), 52.9 years median age, 51 smokers (92.7 %), five with non-squamous NSCLC Stage III (9%), 50 Stage IV (91 %), and performance status (PS) 0-2. ctDNA was detected in 35 patients (64 %), 22 with high and 13 with low ctDNA levels. Overall, 77 % were positive for TP53, 29 % for KRAS, and 11 % for STK11 mutations, more than one alteration was detected in 43 % of samples. Multivariate analysis showed that positive ctDNA was significantly associated with shorter PFS (HR, 4.31, 95 %CI: 2.06-8.99, p < 0.0001), and shorter OS (HR, 3.52, 95 %CI: 1.72-7.19, p < 0.001). Moreover, OS was significantly longer for patients with low ctDNA levels at diagnosis as compared to high (p = 0.01). CONCLUSION We show that ctDNA detection using ultra-deep NGS is an independent prognostic factor in PLHIV with advanced NSCLC.

[PMID: 33948123 PMCID: PMC8053829 DOI: 10.1177/17588359211006983] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 03/11/2021] [Indexed: 12/25/2022] Open
Abstract
Background: The role and timing of whole or stereotaxic brain radiotherapy (BR) in patients with advanced non-small cell lung cancer (aNSCLC) and asymptomatic brain metastases (aBMs) are not well established. This study investigates whether deferring BR until cerebral progression was superior to upfront BR for patients with aNSCLC and aBM. Methods: This open-label, multicenter, phase III trial, randomized (1:1) aNSCLC patients with aBMs to receive upfront BR and chemotherapy: platin–pemetrexed and bevacizumab in eligible patients, followed by maintenance pemetrexed with or without bevacizumab, BR arm, or the same chemotherapy with BR only at cerebral progression, chemotherapy (ChT) arm. Primary endpoint was progression-free survival (PFS), secondary endpoints were overall survival (OS), global, extra-cerebral and cerebral objective response rate (ORR), toxicity, and quality of life [ClinicalTrials.gov identifier: NCT02162537]. Results: The trial was stopped early because of slow recruitment. Among 95 included patients, 91 were randomized in 24 centers: 45 to BR and 46 to ChT arms (age: 60 ± 8.1, men: 79%, PS 0/1: 51.7%/48.3%; adenocarcinomas: 92.2%, extra-cerebral metastases: 57.8%, without differences between arms.) Significantly more patients in the BR-arm received BR compare with those in the ChT arm (87% versus 20%; p < 0.001); there were no significant differences between BR and ChT arms for median PFS: 4.7, 95% confidence interval (CI):3.4–7.5 versus 4.8, 95% CI: 2.4–6.5 months, for median OS: 8.5, 95% CI:.6–11.1 versus 8.3, 95% CI:4.5–11.5 months, cerebral and extra-cerebral ORR (27% versus 13%, p = 0.064, and 30% versus 41%, p = 0.245, respectively). The ChT arm had more grade 3/4 neutropenia than the BR arm (13% versus 6%, p = 0.045); others toxicities were comparable. Conclusion: The significant BR rate difference between the two arms suggests that upfront BR is not mandatory in aNSCLC with aBM but this trial failed to show that deferring BR for aBM is superior in terms of PFS from upfront BR.

Abstract
The new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), now recognised by the World Health Organization as a pandemic, emerged in late 2019 in China [1]. Patients infected with SARS-CoV-2 can develop severe pneumonia and respiratory failure, which often require treatment in intensive care units (ICU) in Western European countries [2]. Oxygen therapy and supportive care are still the main forms of therapy for SARS-CoV-2 pneumonia until suitable anti-infective therapies become available. SARS-CoV-2 infected patients with nonhypercapnic acute hypoxaemic respiratory failure can benefit from high-flow nasal oxygen outside an ICU. The technique appears to be safe for healthcare workers and could well liberate critical ICU resources.https://bit.ly/2Xq80iu

Abstract
Thoracic splenosis is the autotransplantation of splenic tissue in the left thoracic cavity as a result of a splenic injury. This rare pathology is usually asymptomatic and may be discovered on incidental imaging, but the diagnosis often requires invasive procedures such as surgery in order to eliminate a neoplasic origin. We report a rare symptomatic case of a 39-year-old man presenting with chest pain and multiple nodules revealed on a computed tomography scan. The patient underwent a surgical exploration and the pathological studies concluded to a thoracic splenosis. Indeed, the previous medical history of the patient revealed a left thoraco-abdominal traumatism during childhood. The aim of this paper is to emphasize that the diagnosis can now be performed using only imaging techniques such as technetium-99 sulfur colloid or labelled heat-denatured red blood cell scintigraphy to avoid unnecessary invasive procedures including thoracotomy.

Abstract
9072 Background: Thymic carcinomas are an aggressive and difficult to treat subset of thymic epithelial tumors (TETs) that represent a heterogeneous group of rare intrathoracic malignancies. Most of the current knowledge and guidelines tumors rely on surgically-oriented databases focusing on early-stage disease, and small prospective, single-arm trials conducted in metastatic thymic carcinomas, mostly in a refractory, late-line setting. “Réseau tumeurs THYMiques et Cancer” (RYTHMIC) is the nationwide network for TETs in France. The management of any patient has to be systematically discussed on a real-time basis at a national multidisciplinary tumor board; a database is hosted by the French Thoracic Cancer Intergroup (IFCT). Methods: We took advantage of the RYTHMIC prospective database to describe baseline characteristics, analyze treatment strategies, and provide landmark outcomes in a cohort of consecutive patients with thymic carcinoma. The inclusion period was January 2012 to April 2017. Results: A total of 213 patients were analyzed. Overall, 60 (28%) patients were considered as surgical candidates upfront, 91 (43%) received primary chemotherapy, and 62 (29%) received exclusive chemotherapy. Median OS was 49.2 months (IC95%: 34.8-63.6); OS was significantly longer in patients with a lower stage at diagnosis (p < 0.001), who were operated on upfront, as opposed to patients who received primary or exclusive chemotherapy (p < 0.001). Surgery, conducted upfront or after primary chemotherapy, was significantly associated with more prolonged OS (p < 0.001); complete resection and postoperative radiotherapy were also predictors of better outcome (p = 0.018 and p = 0.081, respectively). Exclusive chemotherapy was delivered to 62 patients with advanced disease, who all received platinum-based regimen as first-line treatment; PAC regimen was delivered to 66% of patients. Best objective response to first-line chemotherapy was partial response in 33 (53%) patients. Median PFS was 8.0 months (IC95%: 5.0-11.1). Median OS was 32.9 months (IC95%: 20.6-45.1). Response to first-line chemotherapy and squamous histology were the only significant predictors of OS (p = 0.002 and p = 0.040, respectively). Conclusions: Our cohort is the first to analyze in depth outcomes and treatment strategies in a prospective cohort of consecutive patients with thymic carcinoma. While we confirm the major prognostic impact of surgery, our data highlight the need for optimized multidisciplinary management and innovative therapies as the survival of patients remains limited.

Abstract
9505 Background: We report updated safety and efficacy of DM4-conjugated anti-CEACAM5 ADC from the expansion part of the first-in-human study (NCT02187848; Gazzah A et al. J Clin Oncol. 2019;37:15, 9072) in 92 NSQ NSCLC pts. Methods: CEACAM5 expression was assessed by immunohistochemistry on archived tumor samples. Two cohorts of pts have been analyzed: moderate and high expressors, with CEACAM5 expression at ≥2+ intensity between ≥1% to < 50% and ≥50% of the tumor cell population, respectively. SAR408701 was administered at 100 mg/m2 IV every 2 weeks. Tumor assessments were done every 4 cycles (8 weeks). Primary endpoint was overall response rate (ORR). Results: As of January 2020, 92 pts were treated: 28 moderate and 64 high expressors, with median age 62.5 years (31–91; 42.4% of pts ≥65), 51.1% male, 71.7% ECOG PS ≥1; median of 3 prior treatments (1–10 lines) for advanced disease, including anti-tubulin agents (60.9%) and anti-PD1/PD-L1 (75%). In the moderate expressor cohort, 2 confirmed partial responses (PR) were observed (ORR 7.1%). In the high expressor cohort, 13 pts had confirmed PRs (ORR 20.3% [95% confidence interval 12.27%–31.71%]); 27 (42.2%) had stable disease; ORR of 17.8% was observed in 45 pts who had prior anti-PD1/PD-L1. Pts had a median of 7 (1–49) cycles; median relative dose intensity was 0.98. Six pts discontinued due to treatment-emergent adverse events (TEAEs). Most frequent TEAEs (all grades) were asthenia (38.0%), keratopathy/keratitis (38.0%), peripheral neuropathy (26.1%), dyspnea (23.9%), and diarrhea (22.8%). 31 pts had dose modification due to a TEAE, including dose reduction for keratopathy/keratitis in 10 pts. Hematological toxicity included leukopenia (14.4%), neutropenia (4.4%), and thrombocytopenia (13.3%). Grade ≥3 TEAEs occurred in 47.8% of pts and were assessed as drug-related in 15.2%. Conclusions: SAR408701 shows promising antitumor activity in heavily pretreated advanced NSQ NSCLC pts with high CEACAM5 expression. SAR408701 was well tolerated, with minimal hematological toxicity compared to conventional chemotherapy; keratopathy was reversible and manageable with dose modification. These data support the activity of SAR408701 in NSQ NSCLC CEACAM5 high expressors. A phase 3 trial evaluating the activity of CEACAM5-DM4 ADC monotherapy in comparison with docetaxel in NSQ NSCLC CEACAM5 high expressors after failure of standard first line chemotherapy and anti-PD1/PD-L1 is underway. Clinical trial information: NCT02187848 .

Abstract
9615 Background: Lorlatinib, a third-generation tyrosine kinase inhibitor targeting ALK and ROS1, has been made available in France starting October 2015 through an EAP for advanced, refractory, ALK+ NSCLC after the failure of chemotherapy and TKIs. Besides the landmark, multi-cohort phase II trial that assessed lorlatinib in ALK+ NSCLC, real-life evidence regarding the efficacy and safety, as well as treatment sequences including lorlatinib, is lacking. Methods: We report the cohort of consecutive patients with advanced, refractory, ALK or ROS1+ NSCLC enrolled in the French EAP of lorlatinib from October 2015 to October 2019. Data were collected from medical records by French Cooperative Thoracic Intergroup (IFCT) research study assistants on site. Primary endpoint was progression-free survival. Results: 200 patients were included: 143 (71.5%) ALK+, 57 (28.5%) ROS1+, 87 (44%) men, 127 (66%) never-smokers, and 167 (85%) stage IV disease. Mean age was 59 years. At the time of initiation of lorlatinib, 146 (74%) patients had Central Nervous System (CNS) disease (78 % for ALK+, 63% for ROS1+), 131 (76%) were PS 0/1. Lorlatinib was delivered as 2nd/3rd/4th/5th+ line in 3%/17%/27%/53%of ALK+ patients and in 30%/30%/16%/24%of ROS1+ patients, respectively. 150 (75%), 185 (93%), 138 (69%), and 80 (40%) patients had received prior chemotherapy, crizotinib, 2nd generation TKIs, and brain radiotherapy, respectively. Median PFS and OS from the initiation of lorlatinib were 11.8 (95% CI 7.3-14.6) months and NR (95% CI 18.6-NR) months, respectively for ALK+ patients and 7.6 (95% CI 6.2-10.2) months and 20.9 (95% CI 10.0-NR) months, respectively for ROS1+ patients. ORR and DCR were 46.2% (95% CI 37.6-54.7) and 86.2% (95% CI 80.2-92.1), respectively for ALK+ patients and 47.1% (95% CI 33.4-60.8) and 88.2% (95% CI 79.4-97.1), respectively for ROS1+ patients. CNS ORR was 41.7% (95% CI 33.3-50.1) and 37.7% (95% CI 24.7-50.8), respectively. With a median follow-up of 15.6 (95% CI 14.0-17.6) months, progression under lorlatinib treatment was observed in 71 (50%) ALK+ patients and 35 (61%) ROS1+ patients, and CNS progression in 24 (34%) and 8 (23%) patients, respectively. The safety profile of lorlatinib was consistent with published data. Conclusions: These real-life results confirmed lorlatinib as a major treatment option for patients with advanced refractory ALK or ROS1+ NSCLC.

Abstract
Introduction KRAS mutations are detected in 20% to 30% of NSCLC. However, KRAS mutation subtypes may differently influence the outcome of patients with advanced NSCLC. Methods In the Biomarkers France study, 4894 KRAS mutations (26.2%) were detected in 4634 patients from the 17,664 enrolled patients with NSCLC. Survival and treatment data on noncurative stage III to IV NSCLC were available for 901 patients. First- and second-line treatment effects on progression-free survival and overall survival were analyzed according to the KRAS mutations subtype. Results Over 95% of patients with KRAS mutation were smokers or former smokers who were white (99.5%), presenting with adenocarcinoma (82.5%). The most common KRAS mutation subtype was G12C (374 patients; 41.5%), followed by G12V (168; 18.6%), G12D (131; 14.5%), G12A (62; 6.9%), G13C (45; 5.0%), G13D (31; 3.4%), and others (10; 1%). Approximately 21% of patients had transition mutation and 68.2% had a transversion mutation. G12D and transition mutations were predominant in never-smokers. The median overall survival for patients with KRAS-mutated NSCLC was 8.1 months (95% confidence interval [CI]: 7.5-9.5), without any differences according to the different KRAS subtypes mutations. The median progression-free survival was 4.6 months (95% CI: 4.2-5.1) for first-line treatment and 4.8 months (95% CI: 4.3-6.8) for second-line treatment, without any differences according to the different KRAS subtypes mutations. Conclusions KRAS mutation subtypes influenced neither treatment responses nor outcomes. The KRAS G12C mutation was detected in 41.5% of patients, who are now eligible for potent and specific G12C inhibitors.
