Performances and limits of Bag-Valve-Device for pre-oxygenation and manual ventilation: A comparative bench and cadaver study. Resuscitation 2024; 194:109999. [PMID: 37838142 DOI: 10.1016/j.resuscitation.2023.109999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 10/02/2023] [Accepted: 10/05/2023] [Indexed: 10/16/2023]
Abstract
INTRODUCTION Bag-Valve-Device (BVD) is the most frequently used device for pre-oxygenation and ventilation during cardiopulmonary resuscitation (CPR). A minimal expired fraction of oxygen (FeO2) above 0.85 is recommended during pre-oxygenation while insufflated volume (VTi) should be reduced during manual ventilation. The objective was to compare the performances of different BVD in simulated conditions. METHODS Nine BVD were evaluated during pre-oxygenation: spontaneous breathing patients were simulated on a test lung (mild and severe conditions). FeO2 was measured with and without positive end-expiratory pressure (PEEP). CO2 rebreathing was evaluated. Then, manual ventilation was performed by 36 caregivers (n = 36) from three hospitals on a specific manikin; same procedure was repeated by 3 caregivers (n = 3) on two human cadavers with three of the nine BVD: In non-CPR scenario and during mechanical CPR with Interrupted Chest Compressions strategy (30:2). RESULTS Pre-oxygenation: FeO2 was lower than 0.85 for three BVD in severe condition and for two BVD in mild condition. FeO2 was higher than 0.85 in eight of nine BVD with an additional PEEP valve (PEEP 5 cmH2O). One BVD induced CO2 rebreathing. Manual ventilation: For non-CPR manual ventilation, mean VTi was within the predefined lung protective range (4-8 mL/kg PBW) for all BVD on the bench. For CPR manual ventilation, mean VTi was above the range for three BVD on the bench. Similar results were observed on cadavers. CONCLUSIONS Several BVD did not reach the FeO2 required during pre-oxygenation. Manual ventilation was significantly less protective in three BVD. These observations are related to the different BVD working principles.

Lung Cancer 2023; 185:107379. [PMID: 37757576 DOI: 10.1016/j.lungcan.2023.107379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 09/13/2023] [Accepted: 09/14/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND Small cell lung cancer (SCLC) has a tendency towards recurrence and limited survival. Standard-of-care in 1st-line is platinum-etoposide chemotherapy plus atezolizumab or durvalumab,based on landmarkclinical trials. METHODS IFCT-1905 CLINATEZO is a nationwide, non-interventional, retrospectivestudy of patients with extensive-SCLC receivingatezolizumab plus chemotherapy as part of French Early Access Program. Objectives were to analyse effectiveness,safetyand subsequent treatments. RESULTS The population analyzed included 518 patients who received atezolizumabin 65 participating centers. There were 66.2% male,mean age was 65.7 years; 89.1% had a performance status (PS) 0/1 and 26.6% brain metastases. Almost all(95.9%) were smokers. Fifty-five (10.6%) received at least 1 previous treatment. Median number of atezolizumab injections was 7.0 (range [1.0-48.0]) for a median duration of 4.9 months (95% CI 4.5-5.1). Atezolizumab was continued beyond progression in 122 patients (23.6%) for a median duration of 1.9 months (95% CI: [1.4-2.3]). Best objective response was complete and partialin 19 (3.9%) and 378 (77.1%)patients. Stable diseasewas observed in 50 patients (10.2%). Median follow-up was30.8 months (95% CI: [29.9-31.5]). Median overall survival (OS), 12-, 24-month OS rates were 11.3 months (95% CI: [10.1-12.4]), 46.7% (95% CI [42.3-50.9]) and 21.2% (95% CI [17.7-24.8]). Median real-world progression-free survival, 6-, 12-month rates were 5.2 months (95% CI [5.0-5.4]), 37.5% (95% CI [33.3-41.7]) and 15.2% (95% CI [12.2-18.6]). For patients with PS 0/1, median OS was 12.2 months (95% CI [11.0-13.5]). For patients with previous treatment, median OS was 14.9 months (95% CI [10.1-21.5]). Three-hundred-and-twenty-six patients(66.4%) received subsequent treatment and27 (5.2%) were still underatezolizumabat date of last news. CONCLUSIONS IFCT-1905 CLINATEZO shows reproductibility, in real-life,ofIMpower-133survival outcomes, possibly attributed to selection of patients fit for this regimen, adoption of pragmatic approaches,including concurrent radiotherapy and treatment beyond progression.

VEGFR2 and CD34 expression associated with longer survival in patients with pleural mesothelioma in the IFCT-GFPC-0701 MAPS phase 3 trial. Lung Cancer 2023; 182:107287. [PMID: 37393757 DOI: 10.1016/j.lungcan.2023.107287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/19/2023] [Accepted: 06/24/2023] [Indexed: 07/04/2023]
Abstract
OBJECTIVES VEGF/VEGFR autocrine loop is a hallmark of pleural mesothelioma (PM). We thus assayed the prognostic and predictive values of VEGFR-2 [vascular endothelial growth factor receptor 2 or Flk-1] and CD34, a marker of endothelial cells, in samples from patients accrued in the Mesothelioma Avastin Cisplatin Pemetrexed Study ('MAPS', NCT00651456). MATERIALS AND METHODS VEGFR2 and CD34 expression were assayed using immunohistochemistry in 333 MAPS patients (74.3%), and their prognostic value was evaluated in terms of overall survival (OS) and progression-free survival (PFS) in univariate and multivariate analyses, before validation by bootstrap methodology. RESULTS Positive VEGFR2 or CD34 staining was observed in 234/333 (70.2%) and 322/323 (99.6%) of tested specimens, respectively. VEGFR2 and CD34 staining correlated weakly, yet significantly, with each other (r = 0.36, p < 0.001). High VEGFR2 expression or high CD34 levels were associated with longer OS in PM patients in multivariate analysis (VEGFR2: adjusted [adj.] hazard ratio [HR]: 0.91, 95% confidence interval [CI] [0.88; 0.95], p < 0.001; CD34: adj. HR: 0.86, 95 %CI [0.76; 0.96], p = 0.010), with only high VEGFR2 expression resulting in significantly longer PFS (VEGFR2: adj. HR: 0.96, 95 %CI [0.92; 0.996], p = 0.032). Stability of these results was confirmed using bootstrap procedure. Nevertheless, VEGFR2 expression failed to specifically predict longer survival in bevacizumab-chemotherapy combination trial arm, regardless of whether the VEGFR2 score was combined or not with serum VEGF concentrations. CONCLUSION VEGFR2 overexpression independently correlated with longer OS or PFS in PM patients, such biomarker deserving prospective evaluation as stratification variable in future clinical trials.

Pharmacokinetics, biodistribution and toxicology of novel cell-penetrating peptides. Sci Rep 2023; 13:11081. [PMID: 37422520 PMCID: PMC10329699 DOI: 10.1038/s41598-023-37280-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 06/19/2023] [Indexed: 07/10/2023] Open
Abstract
Cell-penetrating peptides (CPPs) have been used in basic and preclinical research in the past 30 years to facilitate drug delivery into target cells. However, translation toward the clinic has not been successful so far. Here, we studied the pharmacokinetic (PK) and biodistribution profiles of Shuttle cell-penetrating peptides (S-CPP) in rodents, combined or not with an immunoglobulin G (IgG) cargo. We compared two enantiomers of S-CPP that contain both a protein transduction domain and an endosomal escape domain, with previously shown capacity for cytoplasmic delivery. The plasma concentration versus time curve of both radiolabelled S-CPPs required a two-compartment PK analytical model, which showed a fast distribution phase (t1/2α ranging from 1.25 to 3 min) followed by a slower elimination phase (t1/2β ranging from 5 to 15 h) after intravenous injection. Cargo IgG combined to S-CPPs displayed longer elimination half-life, of up to 25 h. The fast decrease in plasma concentration of S-CPPs was associated with an accumulation in target organs assessed at 1 and 5 h post-injection, particularly in the liver. In addition, in situ cerebral perfusion (ISCP) of L-S-CPP yielded a brain uptake coefficient of 7.2 ± 1.1 µl g-1 s-1, consistent with penetration across the blood-brain barrier (BBB), without damaging its integrity in vivo. No sign of peripheral toxicity was detected either by examining hematologic and biochemical blood parameters, or by measuring cytokine levels in plasma. In conclusion, S-CPPs are promising non-toxic transport vectors for improved tissue distribution of drug cargos in vivo.

Neoadjuvant durvalumab for resectable non-small-cell lung cancer (NSCLC): results from a multicenter study (IFCT-1601 IONESCO). J Immunother Cancer 2022; 10:jitc-2022-005636. [PMID: 36270733 PMCID: PMC9594538 DOI: 10.1136/jitc-2022-005636] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/26/2022] [Indexed: 11/07/2022] Open
Abstract
Background The IONESCO (IFCT-1601) trial assessed the feasibility of neoadjuvant durvalumab, for early-stage resectable non-small-cell lung cancer (NSCLC). Methods In a multicenter, single-arm, phase II trial, patients with IB (≥4 cm)-IIIA, non-N2, resectable NSCLC received three doses of durvalumab (750 mg every 2 weeks) and underwent surgery between 2 and 14 days after the last infusion. The primary endpoint was the complete surgical resection rate. Secondary endpoints included tumor response rate, major histopathological response (MPR: ≤10% remaining viable tumor cells), disease-free survival (DFS), overall survival (OS), durvalumab-related safety, and 90-day postoperative mortality (NCT03030131). Results Forty-six patients were eligible (median age 60.9 years); 67% were male, 98% were smokers, and 41% had squamous cell carcinoma. Regarding tumor response, 9% had a partial response, 78% had stable disease, and 13% had progressive disease. Among the operated patients (n=43), 41 achieved complete resection (89%, 95% CI 80.1% to 98.1%)), and eight achieved MPR (19%). The 12-month median OS and DFS rates were 89% (95% CI 75.8% to 95.3%) and 78% (95% CI 63.4% to 87.7%), respectively (n=46). The median follow-up was 28.4 months (12.8–41.1). All patients in whom MPR was achieved were disease-free at 12 months compared to only 11% of those with >10% residual tumor cells (p=0.04). No durvalumab-related serious or grade 3–5 events were reported. The unexpected 90-day postoperative mortality of four patients led to premature study termination. None of these four deaths was considered secondary to direct durvalumab-related toxicity. Conclusions Neoadjuvant durvalumab given as monotherapy was associated with an 89% complete resection rate and an MPR of 19%. Despite an unexpectedly high rate of postoperative deaths, which prevented us from completing the trial, we were able to show a significant association between MPR and DFS.

Abstract
9082 Background: BRAF V600E mutations occur up to 2% of advanced non-small cell lung (NSCLC). Dabrafenib-trametinib (D-T) combination was associated with improved OS rates in phase II study and was approved in the 1st-line setting and further. The IFCT-2004 BLaDE study reports the D-T combination efficacy in a large French real-world multicenter cohort of advanced BRAF V600E-mutated NSCLC. Methods: Patients (pts) with advanced NSCLC harboring BRAF V600E mutation diagnosed between 01.01.2016 and 31.12.2019 and treated with D-T combination (D 300 mg + T 2 mg daily) whatever the treatment line were included. Demographic, clinical, pathological data were collected as well as data of efficacy and reason of treatment discontinuation. The primary endpoint was 12 months-OS rate in pts receiving the D-T as 2nd-line or subsequent treatment (L2+). Results: 163 pts were included in 54 centers through 32 national testing labs: 50.3 % were female, 30.2% never-smokers, 95.1 % had adenocarcinoma and PDL1 was > 1% in 78.2%. Median age was 68.3 years. At D-T initiation, 80.8 % of pts were PS 0/1, 93.9 % were stage IIIB/C ineligible for surgery or local therapy and IV, 20.9% had brain metastases and 27% received D+T as 1st line treatment (L1). At the data cutoff (30.06.2021), median (m) follow-up was 27.4 months [95% CI 22.2-31.9] and 47 pts (28.8%) remained on study treatment. 12 months-OS rate in pts receiving D+T in L2+ (n = 119) was 67.4% [95% CI 57.8-75.3] with a median progression-free survival (mPFS) of 10.4 months [95% CI 7.3-13.1]. In the 44 pts receiving D+T in L1, 12 months-OS rate was also 67.4% [95% CI 51.2-79.3] with a mPFS of 18.2 months [95% CI 7.7-21.3]. Objective response rates were 73.8% [95% CI 65.5 - 82.2] and 82.9% [95% CI 71.4 - 94.4], disease progression was observed as best response in 3.7% [95% CI 0.1 - 7.3] and 0% in L2+ and L1, respectively. Other efficacy results are detailed in the table. D-T discontinuation for toxicity was reported in 10.3% of pts. 51.2% and 43.7% of pts received subsequent treatment in L2+ and L1 respectively. For L2+ pts, subsequent treatments were immunotherapy (IO)-based in 37.2 % and chemotherapy in 58.3%. For L1 pts, subsequent treatments were (IO)-based in 42.9% and chemotherapy in 42.7%. Conclusions: Our series confirms significant efficacy of D-T combination in BRAF V600E-mutated metastatic NSCLC. These results in real-world conditions are consistent with registration studies but also support its use in 1st line setting. [Table: see text]

Abstract
TPS9144 Background: Second generation ALK tyrosine kinase inhibitors (ALK-TKI), including brigatinib, provide substantial therapeutic benefit in first-line treatment of ALK-positive NSCLC patients (pts) but relapse eventually occurs in all pts due to development of drug resistance, possibly caused by emergence of drug-tolerant cells (DTC). Combining chemotherapy to TKI may prevent DTC emergence in preclinical studies, and results in prolonged progression-free survival (PFS) and overall survival in EGFR-mutant NSCLC. We hypothesize that combination of second generation ALK-TKI with chemotherapy will improve clinical outcomes in advanced ALK-positive NSCLC patients. The IFCT-2101 MASTERPROTOCOL ALK trial will evaluate the efficacy and safety of brigatinib and carboplatin-pemetrexed combination in treatment-naïve metastatic ALK-positive NSCLC. Methods: The IFCT-2101 MASTERPROTOCOL ALK randomized, open-label phase II trial will enrol 110 pts in 30 French centers over 24 months. Eligible pts will have metastatic NSCLC with ALK-fusion according to local testing, be untreated for advanced disease, and have an ECOG Performance Status (PS) of 0-1 and at least one measurable lesion per RECIST 1.1. Pts with asymptomatic and stable brain metastases (BM) will be eligible. Exclusion criteria include leptomeningeal metastases. Patients will be randomized 1:1 to receive brigatinib monotherapy (Arm A) or combination brigatinib and carboplatin-pemetrexed therapy (Arm B), with PS (0 vs 1) and BM (presence vs absence) as stratification factors. Brigatinib will be administered at a dose of 90 mg QD for a 7-day lead-in period followed by 180 mg QD continuously, in 28-day cycles. In Arm B, 4 cycles of carboplatin (AUC 5) and pemetrexed (500 mg/m2) therapy every 3 weeks will be added at Day 8 of brigatinib treatment. Treatment will continue until progression, intolerable toxicity or discontinuation. The first 26 pts enrolled in Arm B will represent the population of a safety phase, during which adverse events (AE) will be closely monitored by an independent data monitoring committee. The primary endpoint is investigator-assessed 12-month PFS rate. Secondary endpoints include independently-reviewed 12-month PFS rate, overall response rate (ORR), 12-month intracranial PFS and ORR, incidence, nature and severity of AEs, and impact of ALK-fusion detection, co-mutations and clearance of circulating tumor (ct) DNA (Guardant360) on outcome. Exploratory objectives include the evaluation of early blood ctDNA decrease on patient outcome. The study is enrolling and primary completion date is March 2025. Clinical trial information: NCT05200481.

A Defect of Amphiregulin Release Predicted Longer Survival Independently of YAP Expression in Patients with Pleural Mesothelioma in the IFCT-0701 MAPS Phase 3 Trial. Int J Cancer 2022; 150:1889-1904.

Abstract
The Hippo pathway effector YAP is dysregulated in malignant pleural mesothelioma (MPM). YAP's target genes include the secreted growth factor amphiregulin (AREG), which is overexpressed in a wide range of epithelial cancers and plays an elusive role in MPM. We assayed the expression of YAP and AREG in MPM pathology samples and that of AREG additionally in plasma samples of patients from the randomized phase 3 IFCT‐0701 Mesothelioma Avastin Cisplatin Pemetrexed Study (MAPS) using immunohistochemistry and ELISA assays, respectively. MPM patients frequently presented high levels of tumor AREG (64.3%), a high cytosolic AREG expression being predictive of a better prognosis with longer median overall and progression‐free survival. Surprisingly, tumor AREG cytosolic expression was not correlated with secreted plasma AREG. By investigating the AREG metabolism and function in MPM cell lines H2452, H2052, MSTO‐211H and H28, in comparison with the T47D ER+ breast cancer cell line used as a positive control, we confirm that AREG is important for cell invasion, growth without anchorage, proliferation and apoptosis in mesothelioma cells. Yet, most of these MPM cell lines failed to correctly execute AREG posttranslational processing by metalloprotease ADAM17/tumor necrosis factor‐alpha‐converting enzyme (TACE) and extracell secretion. The favorable prognostic value of high cytosolic AREG expression in MPM patients could therefore be sustained by default AREG posttranslational processing and release. Thus, the determination of mesothelioma cell AREG content could be further investigated as a prognostic marker for MPM patients and used as a stratification factor in future clinical trials.

Abstract
PURPOSE Roughly 20% of patients with non-small-cell lung cancer exhibit locally advanced, unresectable, stage III disease. Concurrent platinum-based chemoradiotherapy is the backbone treatment, which is followed by maintenance immunotherapy, yet with poor long-term prognosis. This phase II trial (IFCT-0803) sought to evaluate whether adding cetuximab to cisplatin and pemetrexed chemoradiotherapy would improve its efficacy in these patients. MATERIALS AND METHODS Eligible patients received weekly cetuximab (loading dose 400mg/m2 day 1; subsequent weekly 250mg/m2 doses until two weeks postradiotherapy). Chemotherapy comprised cisplatin (75mg/m2) and pemetrexed (500mg/m2), both delivered on day 1 of a 21-day cycle of maximally four. Irradiation with maximally 66Gy started on day 22. Disease control rate at week 16 was the primary endpoint. RESULTS One hundred and six patients were included (99 eligible patients). Compliance exceeded 95% for day 1 of chemotherapy cycles 1 to 4, with 76% patients receiving the 12 planned cetuximab doses. Maximal grade 3 toxicity occurred in 63% patients, and maximal grade 4 in 9.6%. The primary endpoint involving the first 95 eligible patients comprised two (2.1%) complete responses, 57 (60.0%) partial responses, and 27 (28.4%) stable diseases. This 90.5% disease control rate (95% confidence interval [95% CI]: 84.6%-96.4%) was achieved at week 16. After median 63.0-month follow-up, one-year and two-year survival rates were 75.8% and 59.5%. Median overall survival was 35.8months (95% CI: 23.5-NR), and median progression-free survival 14.4months (95% CI: 11.2-18.8), with one-year and two-year progression-free survival rates of 57.6% and 34.3%. CONCLUSION These survival rates compare favourably with published data, thus justifying further development of cetuximab-based induction chemoradiotherapy.

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.

IFCT-1502 CLINIVO: real-world evidence of long-term survival with nivolumab in a nationwide cohort of patients with advanced non-small-cell lung cancer. ESMO Open 2021; 7:100353. [PMID: 34953398 PMCID: PMC8764511 DOI: 10.1016/j.esmoop.2021.100353] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 11/17/2021] [Accepted: 11/20/2021] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Immunotherapy using inhibitors targeting immune checkpoint programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) is currently the standard of care in patients with advanced non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS We carried out a nationwide cohort retrospective study of consecutive patients with advanced, refractory NSCLC who received nivolumab as second to later lines of treatment as part of the expanded access program. Key objectives were to assess the efficacy and safety of nivolumab and the efficacy of first post-nivolumab treatment. RESULTS Nine hundred and two patients were enrolled: 317 (35%) with squamous cell carcinoma and 585 (65%) with non-squamous cell carcinoma. Median age was 64 years; there were 630 (70%) men, 795 (88%) smokers, 723 (81%) patients with an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0/1, 197 (22%) patients with brain metastases, and 212 (27%) with liver metastases. Best response was partial response for 16.2% and stable disease (SD) for 30.5%. Progression-free survival and overall survival (OS) rates at 2, 3, and 5 years were 8% and 25%, 6% and 16%, and 4% and 10%, respectively. At multivariate analysis, ECOG PS ≥2 [hazard ratio (HR) = 2.13, 95% confidence interval (95% CI) 1.78-2.55, P < 0.001], squamous histology (HR = 1.17, 95% CI 1.01-1.36, P = 0.04), and presence of central nervous system metastases (HR = 1.29, 95% CI 1.08-1.54, P = 0.005) were significantly associated with lower OS. Four hundred and ninety-two patients received at least one treatment after discontinuation of nivolumab, consisting of systemic therapies in 450 (91%). Radiation therapy was delivered to 118 (24%) patients. CONCLUSION The CLINIVO cohort represents the largest real-world evidence cohort with the use of immune checkpoint inhibitor in advanced, metastatic NSCLC after failure of first-line chemotherapy, with long-term follow-up and analysis of subsequent therapies. Our data confirm the efficacy of nivolumab in a cohort larger than that reported in landmark clinical trials and identify prognostic factors, which reinforces the need for accurate selection of patients for treatment with immune checkpoint inhibitors. Our data indicate that oligoprogression is frequent after nivolumab exposure and provide a unique insight into the long-term survival.

Tailoring maintenance chemotherapy upon response to induction chemotherapy as compared with pemetrexed continuation maintenance in advanced non-squamous NSCLC patients: Results of the IFCT-GFPC-1101 multicenter randomized phase III trial. Lung Cancer 2021; 164:84-90. [PMID: 35051725 DOI: 10.1016/j.lungcan.2021.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 11/16/2021] [Accepted: 11/22/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND Benefit from maintenance in advanced non-squamous non-small cell lung cancer (NS-NSCLC) might favor switch maintenance after disease stabilization (SD) and continuation after objective response (OR). This trial assessed a maintenance strategy conditioned by response to cisplatin-gemcitabine (CG) with G continuation for patients with OR or switch to pemetrexed (P) for patients with SD as compared with a control arm based on the Paramount regimen. METHODS Eligibility criteria: age 18-70 years, ECOG PS 0-1, untreated stage IV NS-NSCLC without EGFR or ALK alteration, ineligibility to bevacizumab. Patients were randomized 1:1 to receive either CG (4 cycles) followed by G maintenance in case of OR followed by P at progression, or switch to P for patients with SD, or 4 cycles of CP followed by P (control arm). Primary endpoint: overall Survival. RESULTS Between 2012 and 2016, 932 patients were randomized (CG: 467, CP: 465) with well-balanced characteristics. 257 patients (56.7%) in the CG arm received maintenance (G: 142, P: 113) versus 277 patients (59.7%) in the CP arm. Median number of maintenance cycles was 5 for G and P (CG induction) and 4 for P (CP induction). OS adjusted HR was 0.97 (95% CI 0.84, 1.13; p = 0.71) with a median of 10.9 months (CG) versus 10.4 (CP). HR for PFS was 0.95 (95% CI 0.83, 1.09; p = 0.45) with a median of 4.8 months for CG versus 4.5 for CP. Safety profile was as expected. CONCLUSIONS Adapting maintenance strategy according to response to induction chemotherapy does not improve patient outcome. CLINICAL TRIAL INFORMATION NCT01631136.

Risque thromboembolique veineux chez les patients traumatisés d’un membre inférieur nécessitant une immobilisation : vers une approche individualisée. ANNALES FRANCAISES DE MEDECINE D URGENCE 2021.

Abstract
Un traumatisme d’un membre inférieur nécessitant une immobilisation est une situation à risque de développement de maladie thromboembolique veineuse (MTEV). Cependant, les recommandations et les pratiques varient notablement d’un pays à un autre et d’un centre à un autre. Cette revue narrative a pour objectifs de décrire l’épidémiologie, la prévention et les algorithmes de prédiction de la MTEV chez les patients traumatisés d’un membre inférieur nécessitant une immobilisation. L’incidence de la MTEV varie selon les études du fait de la grande hétérogénéité des patients inclus (de l’entorse de cheville à une lésion chirurgicale) et du fait des différents critères d’évaluation utilisés. L’incidence des événements thromboemboliques veineux symptomatiques est estimée à 2,0 % (intervalle de confiance à 95 % : 1,3 à 2,7). L’efficacité de la thromboprophylaxie a été démontrée dans des méta-analyses récentes. Cependant, la confiance à accorder à ces résultats est médiocre, car de nombreux essais présentaient des faiblesses méthodologiques. L’étude la plus importante et la plus récente ne montre pas de bénéfice de la prévention par héparine de bas poids moléculaire sur les événements symptomatiques dans une population non ciblée. Ces résultats suggèrent d’adopter une démarche personnalisée en réservant la prophylaxie aux patients à risque. Plusieurs scores existent pour évaluer le risque thromboembolique individuel. La prise en compte des caractéristiques du patient, du traumatisme et de l’immobilisation permet d’identifier un large sous-groupe de patients chez qui la prévention ne semble pas utile et un sous-groupe de patients à haut risque où la prévention devrait être prescrite, voire renforcée. En conclusion, lors d’un traumatisme d’un membre inférieur nécessitant une immobilisation, l’indication d’une thromboprophylaxie devrait être guidée par l’évaluation individuelle du risque thrombotique.

Abstract
Abstract
BACKGROUND
Glioblastoma (GB) is the most aggressive brain primary tumor. The prognosis remains poor mainly due to the invasiveness of glioma cells, radio and/or chemoresistance and GB-induced immunosuppressive environment. Here, we propose to use a local delivery system based on a biocompatible hydrogel containing the chemopeptide urotensin II (hUII) or a biased synthetic analog DAB8-hUII, to “trap” GB cells, and/or to control immune cells expressing its G protein-coupled receptor UT, leading to tumor regression and neurological benefit, in a mouse model of GB resection.
MATERIAL AND METHODS
In vitro, invasion towards UII/analog across different hydrogels or glue of human or murine GB-GFP cell lines was evaluated in Boyden chamber and cloning ring assays. In vivo GB cells were intrastriatally xenografted, then resected while hydrogel- or glue-containing UII/analog was injected in the cavity resection. Behavioral tests, brain immunohistochemical analyses and mouse survival were then investigated.
RESULTS
In vitro, invasive capacity of human U87 and 42MG or murine GL261 and CT2A GB cells was stimulated by UII loaded into hydrogel-based hyaluronic acid supplemented with collagen or other chemicals, PNIPAAm-PEG, or thrombin-fibrin glue. In vivo, injection of UII- or DAB8-hUII-loaded glue into the cavity resection of GL261 and CT2A GB in C57BL/6 mice significantly improved survival compared with tumor and resected experimental conditions. Neurological status was also tested before and after GB resection. We found that GL261 and CT2A cell-bearing mice expressed altered spontaneous activity, emotion and cognitive functions. Intracavity injection of the glue improved resignation and anxiety and increased motor activity and cognition with a best cognitive recovery with hUII and DAB-8-hUII-loaded glue groups. Ex vivo brain analyses revealed high expression of UT and UII in some GB GFP-positive cells and macrophages within GB core and at the interface with the normal brain, GB cells expressing UT migrating along tortuous podocalyxin+ vascular components. In brains bearing hydrogel/hUII glue, vascularization appears modified and GFAP+ astrocytes and F4/80+ macrophages were highly recruited in the border of the cavity, compared with the other conditions.
CONCLUSION
A local glue containing UII may trap GB cells and remodel the tumor microenvironment responsible for survival and cognitive improvements, providing new option in the therapeutic arsenal of GB.

First-Line Afatinib plus Cetuximab for EGFR-Mutant Non-Small Cell Lung Cancer: Results from the Randomized Phase II IFCT-1503 ACE-Lung Study. Clin Cancer Res 2021; 27:4168-4176. [PMID: 34031056 DOI: 10.1158/1078-0432.ccr-20-4604] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 02/12/2021] [Accepted: 05/20/2021] [Indexed: 11/16/2022]
Abstract
PURPOSE Double inhibition of epidermal growth factor receptor (EGFR) using a tyrosine kinase inhibitor plus a monoclonal antibody may be a novel treatment strategy for non-small cell lung cancer (NSCLC). We assessed the efficacy and toxicity of afatinib + cetuximab versus afatinib alone in the first-line treatment of advanced EGFR-mutant NSCLC. PATIENTS AND METHODS In this phase II, randomized, open-label study, patients with stage III/IV EGFR-positive NSCLC were randomly assigned (1:1) to receive afatinib (group A) or afatinib + cetuximab (group A + C). Oral afatinib 40 mg was given once daily; cetuximab 250 mg/m² was administered intravenously on day 15 of cycle 1, then every 2 weeks at 500 mg/m² for 6 months. The primary endpoint was time to treatment failure (TTF) rate at 9 months. Exploratory analysis of EGFR circulating tumor DNA in plasma was performed. RESULTS Between June 2016 and November 2018, 59 patients were included in group A and 58 in group A + C. The study was ended early after a futility analysis was performed. The percentage of patients without treatment failure at 9 months was similar for both groups (59.3% for group A vs. 64.9% for group A + C), and median TTF was 11.1 (95% CI, 8.5-14.1) and 12.9 (9.2-14.5) months, respectively. Other endpoints, including progression-free survival and overall survival, also showed no improvement with the combination versus afatinib alone. There was a slight numerical increase in grade ≥3 adverse events in group A + C. Allele frequency of the EGFR gene mutation in circulating tumor DNA at baseline was associated with shorter PFS, regardless of the treatment received. CONCLUSIONS These results suggest that addition of cetuximab to afatinib does not warrant further investigation in treatment-naïve advanced EGFR-mutant NSCLC.

Abstract
8526 Background: MRD aims to detect circulating biomarkers of micrometastatic disease and ultimately predict recurrences. The IFCT-0703 randomized phase II trial failed to show a benefit of 6 months adjuvant pazopanib (P) vs. placebo after resection of stage I NSCLC (7th TNM edition). The outcome of pts based on their MRD status has been evaluated. Methods: Blood samples were collected in EDTA tubes (Becton Dickinson Company) after surgery (T0), after 3 months (T3) of P or placebo and at the end of treatment (T6). Plasmas were obtained after double centrifugation of total blood. Total nucleic acid was extracted using the Maxwell RSC LV plasma kit (Promega) according to the manufacturer’s protocol. Samples were quantified using the QuBit dsDNA HS Assay kit on a QuBit 3.0 flurometer (Thermo Fisher Scientific). Molecular analysis was performed by next generation sequencing using the Oncomine Lung cfDNA Assay (ThermoFisher Scientific). Two MRD definitions were tested : 1) high level of DNA in the blood or 2) any mutation detected by the standard bioinformatic pipeline was considered present, whatever the allelic fraction. Results: 143 pts were randomized in 29 centers between March 2009 and August 2012, 71 and 72 in the placebo and P arms respectively. Among the 119 pts with evaluable T0 samples, 27 pts recurred and 14 died. Median DNA concentration ([DNA]) was 6.6 ng/ml and an increase of [DNA] of 10 ng/ml was found prognostic of poor DFS and OS, HR=1.4, 95%CI [1.14-1.72], p=0.0016 and HR=1.62, 95%CI [1.15-2.30], p=0.0057 respectively. In 81 pts with available T0-T6 samples, [DNA] variation had no different impact on DFS and OS, in the P arm and the placebo arm. ctDNA mutations (ctDNA+) were detected in 31/119 pts. ctDNA+ were more frequent in samples with high DNA quantity (p=0.0002). Genes mutated at T0 were TP53 in 16, NRAS in 6, MAP2K1 in 2, KRAS in 1, EGFR in 5, BRAF in 1, ALK in 2. 29 pts had 1 mutation, 2 had 2 mutations. DFS and OS were similar between pts with or without ctDNA+ : HR= 1.038 (95%CI 0.438-2.456, p=0.93) and 1.193 (95% CI 0.367-3.882, p=0.77) respectively. Among 27 pts with ctDNA+ at T0 and available sample at T6, 23 had no more mutations at T6. Two pts had a ctDNA+ only at T6 (not at T3), one of them had a recurrence at 7 months. Conclusions: Post-operative ctDNA mutations are found in 26.0% of the pts but their positivity had no impact on DFS or OS. In contrast, DFS and OS were poorer in pts with increased plasma DNA concentration. ctDNA mutations status do not recapitulate the complexity of MRD characterization. NGS will be performed on matched tissues in order to refine MRD definition. Clinical trial information: NCT00775307.

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
Background:B-lymphocyte stimulator (BLyS) is increased in primary Sjögren’s syndrome (pSS) and plays a role in the B-cell hyperactivity thought to contribute to pSS. Belimumab (BEL, anti-BLyS) and rituximab (RTX, anti-CD20) target B cells through distinct and potentially complementary mechanisms.Objectives:To evaluate the safety and efficacy of subcutaneous (SC) BEL/intravenous (IV) RTX combination (BEL/RTX) in patients with pSS.Methods:This Phase 2, double-blind study (GSK Study 201842; NCT02631538) randomised 86 adults with active pSS to 4 treatment arms stratified for baseline EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) scores 5-12 or >12: placebo (PBO; N=13), BEL/RTX (N=24; BEL 200 mg SC weekly to Week [Wk] 24 followed by weekly PBO SC to Wk 52 + RTX 1000 mg IV, Wk 8 + 10), BEL monotherapy (N=24; BEL 200 mg SC weekly to Wk 52) or RTX monotherapy (N=25; RTX 1000 mg IV, Wk 8 + 10). Follow-up was at Wk 68. Safety to Wk 68 was the primary endpoint (safety population; patients received ≥1 dose of study treatment). Secondary/other endpoints (completer population; patients completed treatment and follow-up phase) were ESSDAI score, stimulated salivary flow, CD20+ B-cell count within salivary gland biopsies, patient-reported oral dryness, and EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) score.Results:Baseline demographics and disease characteristics were similar among arms. Adverse events (AEs) were balanced across arms. Serious AEs were infrequent but occurred only in active treatment arms (Table). No unexpected safety issues were identified with BEL/RTX relative to BEL or RTX. Treatment phase and follow-up were completed by 60/86 patients. ESSDAI reductions with BEL/RTX were numerically greater over time than PBO, with greatest difference at Wk 68 (Table), but were not differentiated from monotherapy. Stimulated salivary flow showed a trend favouring BEL/RTX vs PBO over later time points (Table). In contrast with PBO, BEL, and RTX, salivary gland biopsies from BEL/RTX showed almost complete B-cell depletion (Wk 24).

Circulating Tumor DNA as a Prognostic Determinant in Small Cell Lung Cancer Patients Receiving Atezolizumab. J Clin Med 2020; 9:E3861. [PMID: 33261056 PMCID: PMC7760916 DOI: 10.3390/jcm9123861] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 11/16/2020] [Accepted: 11/25/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The IFCT-1603 trial evaluated atezolizumab in small cell lung cancer (SCLC). The purpose of the present study was to determine whether circulating tumor DNA (ctDNA), prospectively collected at treatment initiation, was associated with the prognosis of SCLC, and whether it identified patients who benefited from atezolizumab. METHODS 68 patients were included in this study: 46 patients were treated with atezolizumab and 22 with conventional chemotherapy. Circulating DNA was extracted from plasma and NGS (Next Generation Sequencing) looked for mutations in the TP53, RB1, NOTCH1, NOTCH2, and NOTCH3 genes. ctDNA was detectable when at least one somatic mutation was identified, and its relative abundance was quantified by the variant allele fraction (VAF) of the most represented mutation. RESULTS We found that 49/68 patients (70.6%) had detectable baseline ctDNA. The most frequently identified mutations were TP53 (32/49; 65.3%) and RB1 (25/49; 51.0%). Patients with detectable ctDNA had a significantly lower disease control rate at week 6 compared with patients with no detectable ctDNA, regardless of the nature of the treatment. Detection of ctDNA was associated with a poor OS prognosis. The detection of ctDNA at a relative abundance greater than the median value was significantly associated with poor overall survival (OS) and progression free survival (PFS). Interestingly, the benefit in overall survival (OS) associated with low ctDNA was more pronounced in patients treated with atezolizumab than in patients receiving chemotherapy. Among patients whose relative ctDNA abundance was below the median, those treated with atezolizumab tended to have higher OS than those in the chemotherapy arm. CONCLUSION ctDNA is strongly associated with the prognosis of SCLC patients treated with second-line immunotherapy. Its analysis seems justified for future SCLC clinical trials.

PTEN, ATM, IDH1 mutations and MAPK pathway activation as modulators of PFS and OS in patients treated by first line EGFR TKI, an ancillary study of the French Cooperative Thoracic Intergroup (IFCT) Biomarkers France project. Lung Cancer 2020; 151:69-75. [PMID: 33248711 DOI: 10.1016/j.lungcan.2020.11.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 10/22/2020] [Accepted: 11/10/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Tumor mutation screening is standard of care for patients with stage IV NSCLC. Since a couple of years, widespread NGS approaches used in routine diagnostics to detect driver mutations such as EGFR, KRAS, BRAF or MET allows the identification of other alterations that could modulated the intensity or duration of response to targeted therapies. The prevalence of co-occurring alterations that could affect response or prognosis as not been largely analyzed in clinical settings and large cohorts of patients. Thanks to the IFCT program "Biomarkers France", a collection of samples and data at a nation-wide level was available to test the impact of co-mutations on first line EGFR TKI in patients with EGFR mutated cancers. MATERIALS AND METHODS Targeted NGS was assessed on available (n = 208) samples using the Ion AmpliSeq™ Cancer Hotspot Panel v2 to screen for mutations in 50 different cancer genes. RESULTS This study showed that PTEN inactivating mutations, ATM alterations, IDH1 mutations and complex EGFR mutations were predictors of short PFS in patients with a stage 4 lung adenocarcinoma receiving first line EGFR TKI and that PTEN, ATM, IDH1 and KRAS mutations as well as alterations in the MAPK pathway were related to shorter OS. CONCLUSION These findings may lead to new treatment options in patients with unfavorable genotypes to optimize first line responses.

Switch maintenance chemotherapy versus observation after carboplatin and weekly paclitaxel doublet chemotherapy in elderly patients with advanced non-small cell lung cancer: IFCT-1201 MODEL trial. Eur J Cancer 2020; 138:193-201. [PMID: 32898792 DOI: 10.1016/j.ejca.2020.07.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/28/2020] [Accepted: 07/31/2020] [Indexed: 11/20/2022]
Abstract
PURPOSE Maintenance chemotherapy is a reasonable choice for patients with metastatic non-small cell lung carcinoma (NSCLC) not progressing after induction therapy with a platinum-based doublet. Nevertheless, there have been no studies dedicated to elderly patients. PATIENTS AND METHODS We conducted a randomised trial in patients aged 70-89 years, with advanced NSCLC (with neither EGFR mutation nor ALK rearrangement), who had not progressed after four cycles of monthly carboplatin and weekly paclitaxel in order to compare maintenance with either pemetrexed (500 mg/m2 d1, 22) in patients with non-squamous cell carcinoma or gemcitabine (1,150 mg/m2 d1, 8, 22) in squamous cell carcinoma to simple observation. The patients were required to have a performance status (PS) 0-2, mini-mental score >23, and creatinine clearance ≥45 mL/min. The primary end-point was overall survival (OS). RESULTS 632 patients were enrolled from May 2013 to October 2016. Of the 328 (52.3%) patients randomised after induction therapy, 166 patients were assigned to the observation arm, versus 162 to the switch maintenance arm, 119 of whom received pemetrexed and 43 gemcitabine. The median OS from randomisation was 14.1 months (95% confidence interval [CI]: 12.0-17.0) in the observation arm and 14 months (95% CI: 10.9-16.9) in the maintenance arm (p = 0.72). The median progression-free survival (PFS) from randomisation was 2.7 months (95% CI: 2.6-3.1) in the observation arm versus 5.7 months (95% CI: 4.8-7.1) in the maintenance arm (p < 0.001). CONCLUSION Switch maintenance therapy significantly prolonged PFS but not OS and, thus, should not be proposed to elderly patients with advanced NSCLC.

Abstract
Dès la fin du mois de février 2020, les urgentistes français ont été confrontés à une situation inédite et complexe dans la gestion des cas les plus sévères d’infections pulmonaires associées au nouveau coronavirus (SARSCoV- 2). Les informations en provenance de Chine et les recommandations initiales de l’Organisation mondiale de la santé ont rapidement amené à considérer l’intubation et la ventilation mécanique précoce des malades atteints par la pneumonie de la Covid-19. Or, dès la fin du mois de mars 2020, grâce aux retours d’expérience et de prise en charge, d’abord de la part des réanimateurs et urgentistes italiens, puis espagnols, les pratiques et les recommandations concernant les modalités d’oxygénation et de ventilation des patients Covid-19 ont évolué. Le caractère exceptionnel de cette pandémie et la grande adaptabilité des services de Samu/Smur de France, en l’espace de quelques semaines, pour prendre en charge ces patients oxygénodépendants, justifient que nous en fassions le retour d’expérience, et ce, d’autant plus que nous sommes exposés à un risque de recrudescence d’infections respiratoires graves associées au SARS-CoV-2 à court terme, risquant de saturer une nouvelle fois notre système de santé. Nous détaillons donc ici le retour d’expérience des prises en charge médicales préhospitalières concernant principalement les supports d’oxygénation et de ventilation mécanique.

Abstract
HIV infection is an exclusion criterion in lung cancer trials. This multicentre phase II trial aimed to assess feasibility, efficacy and safety of first-line carboplatin plus pemetrexed (CaP) followed by pemetrexed (P) maintenance in people living with HIV (PLHIV) with advanced non-squamous non-small cell lung cancer (NS-NSCLC).Four cycles of CaP were followed by P-maintenance therapy in patients with Eastern Cooperative Oncology Group performance status ≤2. The primary objective was a disease control rate (DCR) ≥30% after 12 weeks.Of the 61 PLHIV enrolled, 49 (80%) had a performance status of 0-1, and 19 (31%) had brain metastases. Median CD4 lymphocyte count was 418 cells·µL-1 (range 18-1230), median CD4 lymphocyte nadir was 169.5 cells·µL-1 (1-822); 48 (80%) patients were virologically controlled. Four-cycle inductions were achieved by 38 (62%) patients, and 31 (51%) started P-maintenance (median of 4.1 cycles (range 1-19)). The 12-week DCR was 50.8% (95% CI 38.3-63.4) and partial response rate 21.3%. Median progression-free survival and overall survival were 3.5 (95% CI 2.7-4.4) and 7.6 months (5.7-12.8), respectively. Patients with a performance status of 0-1 had the longest median progression-free survival (4.3 months, 95% CI 3.1-5.2) and overall survival (11.9 months, 95% CI 6.4-14.3). During induction, CaP doublet was well tolerated apart from grade 3-4 haematological toxicities (neutropenia 53.8%; thrombocytopenia 35.0%; anaemia 30.0%). Two fatal treatment-related sepses were reported. No opportunistic infections were experienced.In PLHIV with advanced NS-NSCLC, first-line four-cycle CaP induction followed by P-maintenance was effective and reasonably well-tolerated. Further studies should evaluate combination strategies of CaP with immunotherapy in PLHIV.

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
9073 Background: TET are associated with autoimmune disorders (AID) in up to 30% of patients (pts). However, there have been wide variations in the reported prevalence of AID in TET pts in small single-center series. RYTHMIC (Réseau tumeurs THYMiques et Cancer) is a French network mandated to systematically discuss every case of TET. We aimed to describe the prevalence of AID in a large French population. Methods: RYTHMIC database, hosted by IFCT (Intergroupe Francophone de Cancérologie Thoracique), prospectively includes all consecutive pts with a diagnosis of TET discussed in French national or regional tumor boards. We analyzed epidemiologic, clinical and pathological characteristics of pts with TET’s related AID. Results: From January 2012 to December 2019, 2909 pts were included in the database. The mean age at diagnosis of TET was 54 and 52% were male. In the overall population, Masaoka Koga stages were well balanced with 12.6% (n = 187) stage I, 8.8% (n = 131) stage IIa, 8.4% (n = 124) stage IIb, 11.1% (n = 164) stage III and 8.5% (n = 125) stage IV. There were 364 (12.5%) events of AID in 302 pts. 62 pts (17%) had more than 1 AID. Among the events, 236 were myasthenia gravis (MG) (64.8%), 19 Hypo-gammaglobulinemia syndrome (5.2%), 15 pure red cell aplasia (4.1%), 18 thyroiditis (4.9%) and 16 systemic erythematous lupus (4.4%). Diagnosis of AID was mostly done at tumor diagnosis (n = 239, 65.7%) but some patient had AID diagnosed before diagnosis (n = 67, 18.4%) or during follow up (n = 32, 8.8%). Among pts presenting AID, B2 was the most common subtype (n = 133, 36.5%). The incidence of AID per subtype was as follow: A (n = 10/81, 12.3%), AB (n = 48/225, 21.3%), B1 (n = 35/130, 26.9%), B2 (n = 133/295, 45.0%), B3 (n = 46/113, 40.7%), thymic carcinoma (n = 16/275, 5.8%). Conclusions: The prevalence of AID in pts with TET was 12.5%, > 40% in B2 and B3 subtypes. Diagnosis of AID can be delayed compared to the diagnosis of TET. Immunotherapy indication should be carefully assessed in pts with TET other than thymic carcinoma.

Abstract
BACKGROUND Lung cancer in women is on the rise, with a higher proportion occurring in lifelong never-smokers. Lung cancer in never-smokers (LCINS) exhibits a high frequency of driver oncogene alterations. In this study, we aimed to investigate whether exposure to reproductive factors in women with LCINS may modulate the molecular pattern. METHODS All newly diagnosed LCINSs were included in a prospective, observational study (IFCT-1002 BioCAST). Each patient responded to a questionnaire including reproductive factors. Biomarker test results were also collected. RESULTS Two hundred and sixty women were included in this analysis, and 166 alterations were characterized. EGFR mutation frequency proved greater among patients with late menarche (74% in age>14 vs. 40% and 41% for 12-14 and ≤12 years, respectively; P=0.020) and tended to decrease with increasingly late age at menopause. In multivariate analysis, EGFR mutation frequency increased by 23% per increment of 1 year of age at menarche (P=0.048), and by 9% for each year at age at first birth (P=0.035). ALK alteration frequency was greater in women with high parity (50% in≥5 vs. 12% and 7% for 1-4 and nulliparity, respectively; P=0.021). CONCLUSION In a cohort of women LCINSs, female hormonal factors appear to impact molecular pattern.

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.

Weekly paclitaxel plus bevacizumab versus docetaxel as second- or third-line treatment in advanced non-squamous non-small-cell lung cancer: Results of the IFCT-1103 ULTIMATE study. Eur J Cancer 2020; 131:27-36. [PMID: 32276179 DOI: 10.1016/j.ejca.2020.02.022] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Accepted: 02/22/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE Second-line chemotherapy regimens have demonstrated poor benefit after failure of platinum-based chemotherapy in advanced non-squamous non-small-cell lung cancer (nsNSCLC). METHODS In this multicentre, open-label phase III trial, patients with advanced nsNSCLC treated with one or two prior lines, including one platinum-based doublet, were centrally randomised to receive 90 mg/m2 of paclitaxel (D1, D8, D15) plus 10 mg/kg of bevacizumab (D1, D15) every 28 days or docetaxel (75 mg/m2) every 21 days; crossover was allowed after disease progression. Primary end-point was progression-free survival (PFS). ClinicalTrials.gov registration number: NCT01763671. RESULTS One hundred sixty six patients were randomised (paclitaxel plus bevacizumab: 111, docetaxel: 55). The median PFS was longer in patients receiving paclitaxel plus bevacizumab than in patients receveing docetaxel [5·4 months versus 3·9 months, adjusted hazard ratio (HR) 0·61 (95% confidence interval [CI]: 0·44-0·86); p = 0·005]. Objective response rates (ORRs) were 22·5% (95% CI: 14·8-30·3) and 5·5% (95% CI: 0·0-11·5) (p = 0·006), respectively. Median overall survivals were similar (adjusted HR 1·17; p = 0·50). Crossover occurred in 21 of 55 (38·2%) docetaxel-treated patients. Grade III-IV adverse events (AEs) were reported in 45·9% and 54·5% of patients treated with paclitaxel and bevacizumab or docetaxel, respectively (p = NS), including neutropenia (19·3% versus 45·4%), neuropathy (8·3% versus 0·0%) and hypertension (7·3% versus 0·0%). Three patients died due to treatment-related AEs (1·8% in each group). CONCLUSION Weekly paclitaxel plus bevacizumab as second- or third-line improves PFS and ORR compared with docetaxel in patients with nsNSCLC, with an acceptable safety profile. These results place weekly paclitaxel plus bevacizumab as a valid option in this population. CLINICAL TRIALS REGISTRATION NUMBER ClinicalTrials.gov Identifier: NCT01763671.

Development and Validation of a Simplified Prognostic Score in SCLC. JTO Clin Res Rep 2020; 1:100016.

Abstract
Introduction This study aimed at generating a new simplified prognostic score (SPS) using common clinical and biological variables to discriminate a limited number of subgroups of patients with SCLC differing by their overall survival (OS). Methods The SPS was developed exploring the Montpellier University Hospital retrospective database of 401 patients over a 16-year period. All patients had received etoposide - platinum-based chemotherapy as first-line treatment. The SPS development took into account significant determinants of OS in the Cox model, weighted by their regression β coefficients. Validation of the consequent SPS has been done separately in a combined population of 213 patients accrued from two different published trials (NCT03059667 and NCT00930891). Results The significant independent determinants of OS included the following: (1) American Joint Committee on Cancer TNM stage IV (hazard ratio [HR]: 2.52; 95% confidence interval [CI]: 1.91–3.33); (2) Eastern Cooperative Oncology Group performance status greater than 1 (HR: 2.27; 95% CI: 1.79–2.87); (3) the presence of liver metastases (HR: 1.66; 95% CI: 1.29–2.15); and (4) neutrophil-to-lymphocyte ratio greater than 4 (HR: 1.39; 95% CI: 1.11–1.92). The SPS generated with these four variables, segregated three groups (good, intermediate, and poor prognosis) with respective median OS of 26.9 months (95% CI: 20.1–38.9), 11.5 months (95% CI: 9.8–13.0), and 6.8 months (95% CI: 5.8–8.3; log-rank p < 10–4). Harrell's C statistic estimate was 0.68 ± 0.012, suggesting goodness of calibration. In the validation cohort, the SPS segregated the aforementioned three subgroups in a nearly similar manner, with respective median OS: 27.2, 12.3, and 8.6 months (log-rank p < 10–3; Harrell’s C statistic: 0.58 ± 0.02). Conclusions The SPS is easy to calculate in real-life practice and efficiently discriminates three populations with different prognoses. This study deserves further validation of this score in patients with SCLC receiving immunochemotherapy.

Role of the YAP-1 Transcriptional Target cIAP2 in the Differential Susceptibility to Chemotherapy of Non-Small-Cell Lung Cancer (NSCLC) Patients with Tumor RASSF1A Gene Methylation from the Phase 3 IFCT-0002 Trial. Cancers (Basel) 2019; 11:cancers11121835. [PMID: 31766357 PMCID: PMC6966477 DOI: 10.3390/cancers11121835] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 11/12/2019] [Accepted: 11/19/2019] [Indexed: 12/27/2022] Open
Abstract
RASSF1 gene methylation predicts longer disease-free survival (DFS) and overall survival (OS) in patients with early-stage non-small-cell lung cancer treated using paclitaxel-based neo-adjuvant chemotherapy compared to patients receiving a gemcitabine-based regimen, according to the randomized Phase 3 IFCT (Intergroupe Francophone de Cancérologie Thoracique)-0002 trial. To better understand these results, this study used four human bronchial epithelial cell (HBEC) models (HBEC-3, HBEC-3-RasV12, A549, and H1299) and modulated the expression of RASSF1A or YAP-1. Wound-healing, invasion, proliferation and apoptosis assays were then carried out and the expression of YAP-1 transcriptional targets was quantified using a quantitative polymerase chain reaction. This study reports herein that gemcitabine synergizes with RASSF1A, silencing to increase the IAP-2 expression, which in turn not only interferes with cell proliferation but also promotes cell migration. This contributes to the aggressive behavior of RASSF1A-depleted cells, as confirmed by a combined knockdown of IAP-2 and RASSF1A. Conversely, paclitaxel does not increase the IAP-2 expression but limits the invasiveness of RASSF1A-depleted cells, presumably by rescuing microtubule stabilization. Overall, these data provide a functional insight that supports the prognostic value of RASSF1 gene methylation on survival of early-stage lung cancer patients receiving perioperative paclitaxel-based treatment compared to gemcitabine-based treatment, identifying IAP-2 as a novel biomarker indicative of YAP-1-mediated modulation of chemo-sensitivity in lung cancer.

Independent prognostic value of ultra-sensitive quantification of tumor pre-treatment T790M subclones in EGFR mutated non-small cell lung cancer (NSCLC) treated by first/second generation TKI, depends on variant allele frequency (VAF): Results of the French cooperative thoracic intergroup (IFCT) biomarkers France project. Lung Cancer 2019; 140:19-26. [PMID: 31841714 DOI: 10.1016/j.lungcan.2019.10.013] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 10/09/2019] [Accepted: 10/11/2019] [Indexed: 01/12/2023]
Abstract
OBJECTIVES T790M mutations inEGFR-mutated non-small cell lung cancer (NSCLC) account for nearly 50% of acquired resistance mechanisms to EGFR-TKIs. Earlier studies suggested that tumor T790M could also be detected in TKI-naïve EGFR-mutated NSCLC. The aim of the study is to assess the prevalence and clinical significance of quantification of tumor pre-treatment T790M subclones. MATERIALS AND METHODS We analyzed 366 EGFR-mutated NSCLC patients of the real-life IFCT Biomarkers France study with available pre-treatment formalin-fixed paraffin-embedded (FFPE) tumor DNA before treatment by first/second-generation EGFR-TKI. We used ultra-sensitive Droplet Digital Polymerase Chain Reaction (ddPCR) QX200 (BIO-RAD®, Hercules, CA, USA). All samples were tested in duplicate. RESULTS ddPCR identified T790M in 19/240 specimens (8%). T790M-positive and T790M-negative populations were not different for clinical baseline characteristics. T790M Variant Allele Frequency (VAF) was > 0.01% <0.1%, > 0.1% <1%, > 1% <10%, and >10% in five (26.3%), six (31.6%), six (31.6%), and two (10.5%) patients, respectively. T790M VAF was >0.1% in 11/13 (84%) patients with rapid (<3 months) or usual progression (3-20 months) compared to 0/3 with low progression (>20 months) (p = 0.02). In a Cox model, T790M mutation positivity was correlated with overall survival (OS) and progression-free survival (PFS) for 10% > VAF >1% (hazard ratio [HR] = 2.83, 95% confidence interval [CI] 1.13-7.07, p = 0.03; HR=3.62, 95%CI 1.43-4.92, p = 0.007, respectively) and for VAF >10% (HR = 19.14, 95%CI 4.35-84.26, p < 0.001; HR = 17.89, 95%CI 2.21-144.86, p = 0.007, respectively). CONCLUSION Ultra-sensitive detection of tumor T790M mutation concerned 8% of EGFR-mutated TKI-naïve NSCLC patients and has a negative prognostic value only for T790M VAF over 1%.

Abstract
INTRODUCTION Patients with stage IV non-small-cell lung cancer (NSCLC) and BRAF V600 mutations may benefit from targeted therapies. Chemotherapy outcomes are little known in this population. METHODS The French Cooperative Thoracic Intergroup (IFCT) Biomarkers France study was a national prospective cohort study aiming to describe the molecular characteristics and clinical outcome of all consecutive NSCLC patients (N = 17,664) screened for molecular alterations. We used this data set to set up a case-control analysis. Cases had stage IV BRAF-mutated (BRAF-MT) NSCLC, whereas controls had NSCLC that was wild-type for EGFR, KRAS, HER2, BRAF, PIK3CA and ALK. Each case was matched for sex, age at diagnosis and smoking status to two controls randomly selected. RESULTS Overall, 83 cases with BRAF mutant disease (66.3% V600E) were matched to 166 controls. Five cases received tyrosine kinase inhibition in the first-line and 16 in the second-line. All others were treated with standard chemotherapy. There was no significant difference in first-line and second-line progression-free survival (PFS) between the groups, as well as in the disease control rate, BRAF mutation was not found to be prognostic of overall survival. We found no significant difference in outcome between the treatment types used in first-line or second-line in patients with BRAF-MT disease compared with controls nor between BRAF V600E or non-V600E compared with controls. CONCLUSIONS BRAF mutation is not a strong prognostic factor in NSCLC. Although taxan-based therapy shows poorest PFS in first-line, no chemotherapy regimen was associated with prognosis.
