Early mortality in real-life nationwide epidemiological study on lung cancer in nonacademic French public hospitals

Background: Each decade since 2000, the French College of General Hospital Pulmonologists (CPHG) conducts a real-life nationwide prospective epidemiological, observational, multicenter study on lung cancer (LC). In 2020, the CPHG constituted the third cohort, KBP-2020-CPHG. We reported here the data on one-month and three-month mortality among general population of this cohort and compared them with 2010 cohort. Methods: Collection of all consecutive LC histologically or cytologically confirmed between 01/01 and 12/31/2020 in non-academic public hospital pulmonology or oncology units in France. A Scientific Committee controlled inclusion exhaustivity and quality in each center. Results: 82 centers collected 8,999 patients in 2020. One-month mortality was 8.8% (734/8,999) and 9.7% (680/7,051) in 2010. Three-month mortality was 21.5% (1,771/8,999) in 2020 and 23.3% (1,624/7,051) in 2010 (Table 1). According to sex, mortality at one and three months mainly affected men (525/734;71.5% and 1,259/1,771;71.1% respectively). Mean age at diagnosis was older than in the cohort population (67.8 y-o);respectively 69.9 and 69.8 at one and three months. At diagnosis, patients were in poorer ECOG mainly grade 2 (211/697;30.3%) or 3 (194/697;27.8%) for one-month and mainly grade 1 (549/1,703;32.2%) or 2 (547/1,703;32.1%) for three-month mortality. Among ECOG grade 3 and 4, 34.8% (194/557) and 57.1% (93/163) were dead at one month respectively;63.5% (350/551) and 83.4% (136/163) respectively were dead at three months. According to histology, adenocarcinoma was the most common (308/734;42%), followed by small cell lung cancer (170/734;23.2%) at one-month;adenocarcinoma was also the most common (822/ 1,771;46.4%), followed by squamous cell carcinoma (380/1771;21.5%) at three-month mortality. Most patients who died early were stage 4, metastatic/disseminated (respectively 625/702;89% and 1,488/1,715;86.8% for one- and three-month mortality). In patients with COVID19 infection (n=547), mortality at one and three months was respectively 36.4% (174/478) and 46.7% (228/ 488). Conclusions: Early mortality has not improved over the two decades and remains high. KBP- 2020-CPHG study was performed during COVID-19 pandemic, which may have generated delays in diagnosis and limited access to care and hospital. Early mortality at one and three months concerned mostly men, mean age nearly 70 y-o, adenocarcinoma, metastatic disease and frail patients. This confirms the potential value of LC screening program in a targeted population.

LBA47 Activity of OSE-2101 in HLA-A2+ non-small cell lung cancer (NSCLC) patients after failure to immune checkpoint inhibitors (IO): Final results of phase III Atalante-1 randomised trial

Background: OSE2101 (Tedopi®) is an anticancer vaccine (modified epitopes restricted to HLA-A2+ from 5 tumor-associated antigens). Atalante-1 is a randomized phase 3 trial of OSE2101 vs Standard of Care (SoC docetaxel or pemetrexed) in pretreated HLA-A2+ patients with advanced NSCLC, with IO as last treatment. Methods: EGFR and ALK negative NSCLC patients, ECOG PS 0-1 were randomized 2:1 to receive OSE2101 subcutaneously Q3W for 6 cycles, followed by maintenance Q8W for 1 year and Q12W until progression, versus SoC (docetaxel or pemetrexed Q3W). Primary endpoint was OS (initial hypothesis of HR 0.7 for 401 pts). Secondary endpoints were disease control rate (DCR), quality of life (QoL - EORTC QLQ-C30/LC13), and Progression free survival (PFS). Toxicities were reported using CTCAE 5.0. Positive pre-specified analyses (ESMO 2020 #1260MO) identified a Population of Interest (PoI) comprised by patients with IO secondary resistance defined as failure after a minimum of 12 weeks IO in sequential CT-IO patients. Due to the risk of COVID-19 pandemic on data integrity, the study was stopped prematurely following IDMC recommendations. PoI was chosen as primary population for the final analysis. Results: 219 pts were enrolled: median age 65 years, 29% female, 10% never-smoker, 70% non-squamous. 183 (84%) pts received sequential CT-IO from whom 118 pts (54%) complied with the definition of PoI, with otherwise similar characteristics that the overall population. In PoI, mOS was 11.1 mo for OSE2101 vs 7.5 for SoC [HR 0.59 (0.38-0.91) p= 0.02]. 6 mo-DCR 25% vs 24% (NS), mPFS 2.7 mo vs 3.4 (NS), ORR 8% vs 18% (p=0.07). Post progression survival was 7.7 mo vs 4.6 [HR 0.46 p= 0.004], time to worsening ECOG PS 8.6 mo vs 3.3 [HR 0.45 p= 0.0005]. In the total population, HR for OS was 0.86 (0.62-1.19) p=0.36. QoL Global Health Status was maintained for OSE2101 (p<0.05). Severe Adverse Events were 38% vs 68% (p<0.001). There was no TEAE of concern in the OSE2101 group. Conclusions: OSE2101 had a favorable benefit/risk of versus SoC in advanced HLA-A2+ NSCLC patients. HR for OS improved from 0.86 to 0.59 in patients with secondary resistance to IO with a meaningful gain of median OS of 3.6 months with OSE2101.

Guide for follow-up of patients with SARS-CoV-2 pneumonia. Management proposals developed by the French-language Respiratory Medicine Society. Version of 10 May 2020 / Guide pour le suivi respiratoire des patients ayant présenté une pneumonie à SARS-CoV-2. Propositions de prise en charge élaborées par la Société de pneumologie de langue française. Version du 10 mai 2020

The French-language Respiratory Medicine Society (SPLF) proposes a guide for the follow-up of patients who have presented with SARS-CoV-2 pneumonia. The proposals are based on known data from previous epidemics, on acute lesions observed in SARS-CoV-2 patients and on expert opinion. This guide proposes a follow-up based on three categories of patients: (1) patients managed outside hospital for possible or proven SARS-CoV-2 infection, referred by their physician for persistent dyspnoea; (2) patients hospitalized for SARS-CoV-2 pneumonia in a medical unit; (3) patients hospitalized for SARS-CoV-2 pneumonia in an intensive care unit. The subsequent follow-up will have to be adapted to the initial assessment. This guide emphasises the possibility of others causes of dyspnoea (cardiac, thromboembolic, hyperventilation syndrome…). These proposals may evolve over time as more knowledge becomes available.

Propositions de prise en charge élaborées par la Société de Pneumologie de Langue Française. Version du 10 novembre 2020.

The French-speaking Respiratory Medicine Society (SPLF) proposes a guide for the management of possible respiratory sequelae in patients who have presented with SARS-CoV-2 pneumonia (COVID-19). The proposals are based on known data from previous epidemics, preliminary published data on post COVID-19 follow-up and on expert opinion. The proposals were developed by a group of experts and then submitted, using the Delphi method, to a panel of 22 pulmonologists. Seventeen proposals were validated ranging from additional examinations after the minimum assessment proposed in the SPLF monitoring guide, to inhaled or systemic corticosteroid therapy and antifibrotic agents. These proposals may evolve over time as knowledge accumulates. This guide emphasizes the importance of multidisciplinary discussion.

The GCO-002 CACOVID-19 cohort: A French nationwide multicenter study of COVID-19 infected cancer patients and consequences on cancer management

Background: The novel COVID-19 outbreak spread rapidly around the world. Cancer patients (pts) consist of a highly vulnerable group due to underlying malignancy and/or treatment-induced immunosuppression. A high mortality rate from COVID-19 in cancer pts was previously reported. France is the fourth most affected country, with more than 150,000 infected individuals and over 28,000 deaths. GCO-002 CACOVID-19 study is a large French nationwide cohort of COVID-19 pts with solid tumors with the aim to identify risk factors of COVID-19 severity and evaluate impact on cancer treatment. Methods: Bispective multicenter cohort set up by the French Cooperative Groups in solid cancers: ANOCEF-IGCNO (CNS tumors), ARCAGY-GINECO (gynecological and breast cancers), FFCD (digestive cancers), GERCOR (digestive and other solid cancers), GORTEC/intergroupe ORL (head and neck cancers (H&N), and IFCT (thoracic cancers). French pts with solid cancers and COVID-19 diagnosed since 1 March 2020 were accrued. Exclusion criteria: pts treated curatively > 5 years ago. Results: From 6 April to 15 May 2020, 835 pts from 136 institutions (general hospitals 35%, university hospitals 35%, private centers 25%, cancer centers 5%) were registered. Men: 61%, median age: 69 years (20-100). Digestive cancers: 43% (16%/9% colorectal/pancreatic cancers), lung cancers: 22%, gynecological: 14%, (9% breast cancers), H&N: 10%, CNS: 4%, urologic cancers: 3%. Advanced or metastatic: 61%. Within 3 months before COVID-19 diagnosis, 69% of pts received a systemic anticancer treatment (chemotherapy, targeted or immune therapy) and 22% a local therapy (surgery, radiotherapy or local destruction). Diagnosis of COVID-19 was confirmed by RT-PCR, CT-scan or both in 91% or serology in 1.4%. COVID was treated in the same oncological center in 78%. During the follow-up period (mean 14 days), 208 (25%) pts died, including 173 (21%) COVID-19 related deaths. Conclusions: This first nationwide study of cancer pts with COVID-19 from France reports a high mortality rate. Updated and detailed data on anti-cancer treatments, risk factors of severe and fatal COVID-19 and impact of COVID-19 on cancer management will be presented.

Activity of OSE-2101 in HLA-A2+ non-small cell lung cancer (NSCLC) patients after failure to immune checkpoint inhibitors (ICI): Step 1 results of phase III ATALANTE-1 randomised trial

Background: Tedopi® is an anticancer vaccine with modified neoepitopes restricted to HLA-A2+ targeting five tumor-associated antigens frequently expressed in lung cancer: CEA, HER2, MAGE2, MAGE3 and P53. ATALANTE-1 was a randomized, open-label, 2-Step phase 3 study comparing the efficacy of Tedopi® with standard treatment (SoC) in HLA-A2+ NSCLC patients in 2nd or 3rd line treatment after progression on ICI. Methods: HLA-A2+ NSCLC patients, EGFR and ALK negative, having progressed to platinum-based chemotherapy (CT) and anti-PD(L)1, ECOG PS 0-1 were randomized 2:1 to receive Tedopi® subcutaneously Q3W for 6 cycles, followed by maintenance Q8W up to first year, then Q12W, or SoC (docetaxel 75 mg/m2 Q3W or pemetrexed 500 mg/m2 Q3W). The Step-1 hypotheses were based on the evaluation of 1y-OS rate (Fleming design: H0 futility boundary at 25%;H1 alternative efficacy: 40% of OS rate at 12 months). Step-2 was a superiority study with OS as primary endpoint. Results: At cutoff of February 2020, 99 patients (Tedopi® n=63;SoC n=36) were randomized and analyzable for Step-1. The 1y-OS was 29/63 (46%) [95%CI 33-59]) in Tedopi® group and 13/36 (36%) [95%CI 21-54] in SoC. The Step-1 endpoint has shown a lower limit of the 95% confidence interval above the futility boundary (25%) with an OS estimate of 10% above the estimate of SoC. Secondary endpoints and subgroup data will be further presented. Grade 3-4 related TEAEs were 11 % in Tedopi® group and 43 % in SoC. There was no related grade 5 TEAE. Related TEAE leading to withdrawal from the study were also less frequent in Tedopi® group (6%) versus SoC (14%). Due to the risk of COVID-19 pandemic on data integrity, following recommendation of the Independent Data Monitoring Committee and Steering Committee, the decision was taken to early terminate the study at Step-1 and definitely stop new accrual while continuing the OS follow-up in all patients. Conclusions: The Step-1 primary endpoint was positively achieved with a 1y-OS rate of 46% and a good safety profile. Step-1 results shown a favorable benefit/risk of Tedopi® over SoC as 2nd or 3rd line treatment in advanced HLA-A2+ NSCLC patients after failure to ICI.
