Efficacy of chemotherapy according to BRCA status in patients with high-grade serous ovarian carcinoma at first platinum-sensitive relapse.

OBJECTIVE: Chemotherapy for high-grade serous ovarian cancers in platinum-sensitive relapse includes carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin. According to in vitro data, BRCA mutated patients are sensitive to replicative stress agents but BRCA status is not yet used for the choice of chemotherapy at relapse. Our aim was to assess these doublets according to BRCA status in first platinum-sensitive relapse. METHODS: The ESME ovarian cancer database comprises a multicenter retrospective cohort of patients with ovarian cancer treated in French cancer centers between January 2011 and December 2017. Patients with high-grade serous ovarian cancers at first platinum-sensitive relapse who received one of these doublets were included. The objective was to compare progression-free survival of each chemotherapy doublet according to BRCA status. RESULTS: Among the 10 263 patients in the database, 1539 patients had a first platinum-sensitive relapse: 825 BRCA wild type patients (53.6%) and 304 BRCA mutated patients (19.8%) (7 patients had a homologous recombination mutation and BRCA status was unkown for 403 patients). Median progression-free survival was longer in BRCA mutated patients than in BRCA wild type patients when receiving carboplatin/pegylated liposomal doxorubicin without maintenance treatment (15.8 vs 11.8 months; p<0.001). In contrast, we observed no difference in patients treated with carboplatin/paclitaxel (14.6 vs 14.3 months, respectively; p=0.70) or in those treated with carboplatin/gemcitabine (12.0 vs 9.8 months, respectively; p=0.18). In BRCA wild type patients without maintenance, better progression-free survival occurred with carboplatin/paclitaxel (median progression-free survival 14.3 months) than with carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin (9.8 and 11.8 months, respectively; p=0.017). In BRCA mutated patients without maintenance, there was no difference between the three doublets (median progression-free survival of 14.6, 12.0, and 15.8 months with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin, respectively; p=0.40). CONCLUSION: While treatment with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin shows comparable efficacy in BRCA mutated patients, treatment with carboplatin/paclitaxel appears to be more effective than carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin in BRCA wild type patients with high-grade serous ovarian cancers at first platinum-sensitive relapse.

An Adjusted Treatment Comparison Comparing Amivantamab Versus Real-World Clinical Practice in Europe and the United States for Patients with Advanced Non-Small Cell Lung Cancer with Activating Epidermal Growth Factor Receptor Exon 20 Insertion Mutations.

INTRODUCTION: Patients with advanced, epidermal growth factor receptor (EGFR)-mutated, non-small cell lung cancer (NSCLC) with Exon 20 insertion mutations (Exon20ins) have poor prognoses, exacerbated by a previous lack of specific treatment guidelines and unmet need for targeted therapies. Amivantamab, an EGFR and MET bispecific antibody, demonstrated efficacy and tolerability in patients with advanced EGFR-mutated NSCLC with Exon20ins following platinum-based therapy in CHRYSALIS (NCT02609776; Cohort D+). Since CHRYSALIS was single-arm, individual patient data (IPD)-based adjusted analyses versus similar patients in real-world clinical practice (RWCP) were conducted to generate comparative evidence. METHODS: RWCP cohorts were derived from seven European and US real-world sources, comprising patients fulfilling CHRYSALIS Cohort D+ eligibility criteria. Amivantamab was compared with a basket of RWCP treatments. Differences in prognostic characteristics were adjusted for using inverse probability weighting (IPW; average treatment effect among the treated [ATT]). Balance between cohorts was assessed using standardized mean differences (SMDs). Overall response rate (ORR; investigator- [INV] and independent review committee-assessed [IRC]), overall survival (OS), progression-free survival (PFS; INV and IRC) and time-to-next treatment (TTNT) were compared. Binary and time-to-event endpoints were analyzed using weighted logistic regression and proportional hazards regression, respectively. RESULTS: Pre-adjustment, baseline characteristics were comparable between cohorts. IPW ATT-adjustment improved comparability, giving closely matched characteristics. ORR (INV) was 36.8% for amivantamab versus 17.0% for the adjusted EU + US cohort (response rate ratio [RR]: 2.16). Median OS, PFS (INV) and TTNT were 22.77 versus 12.52 months (hazard ratio [HR]: 0.47; p < 0.0001), 6.93 versus 4.17 months (HR: 0.55; p < 0.0001) and 12.42 versus 5.36 months (HR: 0.44; p < 0.0001) for amivantamab versus the adjusted EU + US cohort, respectively. Results were consistent versus EU- and US-only cohorts, and when using IRC assessment. CONCLUSION: Adjusted comparisons demonstrated significantly improved outcomes for amivantamab versus RWCP, highlighting the value of amivantamab in addressing unmet need in patients with advanced EGFR Exon20ins NSCLC following platinum-based therapy. TRIAL REGISTRATION: CHRYSALIS: NCT02609776.

Impact of immune checkpoint inhibitors on the management of locally advanced or metastatic non-small cell lung cancer in real-life practice in patients initiating treatment between 2015 and 2018 in France and Germany.

OBJECTIVES: To describe the impact of immune checkpoint inhibitors (ICIs) on treatment patterns and survival outcomes in patients with locally advanced or metastatic non-small cell lung cancer (aNSCLC) in France and Germany. MATERIALS AND METHODS: Patients with aNSCLC without known ALK or EGFR mutations receiving first-line (1L) therapy were included from (i) the retrospective Epidemiological-Strategy and Medical Economics Advanced and Metastatic Lung Cancer cohort (ESME-AMLC, France; 2015-2018) and (ii) the prospective Clinical Research platform Into molecular testing, treatment and outcome of non-Small cell lung carcinoma Patients platform (CRISP, Germany; 2016-2018). Analyses were stratified according to histology. Survival outcomes were estimated using Kaplan-Meier methodology and stratified by year of 1L therapy. Data sources were analysed separately. RESULTS: In ESME-AMLC and CRISP, 8,046 and 2,359 patients were included in the study, respectively. In both countries, approximately 20 % of all patients received pembrolizumab monotherapy as 1L treatment in 2018. In ESME-AMLC, the proportion receiving an ICI over the course of treatment (any line) increased from 42.2 % (2015) to 56.1 % (2018) in patients with squamous histology, and 28.9 % to 51.9 % with non-squamous/other; in CRISP, it increased from 50.6 % (2016) to 65.2 % (2018) with squamous histology, and 40.8 % to 62.7 % with non-squamous/other. Two-year overall survival from 1L initiation was 36.8 % and 25.6 % in the squamous cohorts and 36.5 % and 30.8 % in the non-squamous/other cohorts in ESME-AMLC and CRISP, respectively. No significant change in overall survival was observed over time; however, the follow-up time available was limited in the later years of the analysis. CONCLUSION: The results of this joint research from two large clinical databases in France and Germany demonstrate the growing use of ICIs in the management of aNSCLC. Future analyses will allow for the evaluation of the impact of ICIs on long-term survival of patients with aNSCLC.

Effectiveness of Nivolumab in Second-Line and Later in Patients with Advanced Non-Small Cell Lung Cancer in Real-Life Practice in France and Germany: Analysis of the ESME-AMLC and CRISP Cohorts.

This study reports characteristics and outcomes in patients with locally advanced or metastatic non-small cell lung cancer (aNSCLC) receiving nivolumab in second-line or later (2L+) in France and Germany between 2015 and 2020. Patients with aNSCLC (stage IIIB-C/IV) receiving nivolumab in 2L+ were included from the retrospective Epidemiological Strategy and Medical Economics of Advanced and Metastatic Lung Cancer cohort (ESME-AMLC, France; 2015-2019) and Clinical Research platform Into molecular testing, treatment and outcome of non-Small cell lung carcinoma Patients (CRISP, Germany; 2016-2020). Overall, 2262 ESME-AMLC and 522 CRISP patients were included. Median treatment duration (95% confidence intervals) was 2.8 months (2.5-3.2) in squamous and 2.5 months (2.3-2.8) in non-squamous/others patients in ESME-AMLC, and 2.3 months (1.4-3.1) and 2.3 months (2.0-2.8), respectively in CRISP. One-year and two-year overall survival (OS) were 47.2% and 26.7% in squamous and 50.8% and 32.8% in non-squamous/others patients in ESME-AMLC, and 43.1% and 20.9%, and 37.7% and 18.9%, respectively in CRISP. Poorer performance score and shorter time from start of previous line of therapy initiation were significantly associated with shorter treatment duration and OS. This study confirms, in real-world clinical databases, the efficacy of nivolumab previously observed in clinical trials.

A Real-World Study of Patients with Advanced Non-squamous Non-small Cell Lung Cancer with EGFR Exon 20 Insertion: Clinical Characteristics and Outcomes.

BACKGROUND: In Europe, few data regarding the characteristics of EGFR exon 20 insertion (20ins) mutations in non-small cell lung cancer (NSCLC) are available. OBJECTIVE: Using a large real-world cohort, we assessed the incidence, characteristics, and outcomes of patients with non-squamous (nsq) NSCLC harboring EGFR exon 20ins. PATIENTS AND METHODS: The Epidemio-Strategy and Medical Economics advanced and metastatic lung cancer data platform including advanced/metastatic nsqNSCLC patients from January 2015 was analyzed (cut-off date: June 30, 2020). Characteristics, epidermal growth factor receptor (EGFR) mutation and other mutations, treatment patterns, and clinical outcomes were assessed for patients harboring EGFR exon 20ins, common EGFR mutations, other EGFR mutations, and wild-type EGFR. Survival parameters were estimated by the Kaplan-Meier method in these four groups. RESULTS: Out of 9435 nsqNSCLC patients tested for EGFR, 1549 (16.4%) had a mutation, including 61 with EGFR exon 20ins (3.9% of all mutated EGFR). These 61 patients had a mean age of 63.6 years, were mostly female (68.9%) and non-smokers (55.7%), with de novo stage IV disease (73.8%) and performance status 0-1 (76.9%). Almost all patients (95.1%) with exon 20ins received systemic therapy (median, three lines). First-line systemic treatments consisted mainly of combination chemotherapy (70.7%), single-agent EGFR tyrosine kinase inhibitors (10.3%), and single-agent immunotherapy (5.2%). After a median follow-up of 25.0 (95% confidence interval [CI] 22.3-32.4) months, the median real-world overall survival was 24.3 (19.1-32.6) months in patients with exon 20ins compared to 35.4 (95% CI 32.6-37.5) in patients with common EGFR mutation (n = 1049) (p = 0.049) and 19.6 (95% CI 18.6-20.5) in patients with wild-type EGFR (n = 7866) (p = 0.2). CONCLUSIONS: This large national study in nsqNSCLC patients confirms that EGFR exon 20ins is a rare condition (0.6%). The prognosis associated with exon 20ins appears to be in line with that of wild-type EGFR, but worse than common EGFR mutations, highlighting the need for advancements for this rare population.

2008 French national guidelines for the treatment of venous thromboembolism in patients with cancer: report from the working group.

Venous thromboembolism (VTE) is a major therapeutic issue in cancer patients. Advances in this field and heterogeneities in clinical practices prompted us to establish guidelines in the management of VTE in cancer patients according to the SOR (Standards, Options and Recommendations) methodology. A literature review of the studies published on this topic between 1999 and 2007 was performed. The guidelines were developed from the analysis of 38 out of 418 publications selected. They were peer-reviewed by 65 independent experts. The treatment of VTE in patients with cancer, including those with intracranial malignancies, should be based on low-molecular-weight heparins administered at therapeutic doses for at least 3 months. In the event of recurrent VTE, pulmonary embolism with hemodynamic failure or contra-indication to anticoagulant treatment, the indications and usages of vena cava filters and thrombolytic drugs should be the same as in non-cancer patients.

The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. OBJECTIVES: To update clinical practice guidelines for first line palliative chemotherapy in patients with metastatic colorectal cancer previously validated in 1995, then updated in 1997 and published again in 1998. These recommendations do not cover second line treatment. METHODS: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guidelines have been developed, they are reviewed by independent reviewers. RESULTS: This article is a summary version of the updated clinical practice guidelines with algorithms. The main questions addressed by the expert group in this update concerned (1) Which patients should be treated? (2) What is the best treatment duration? (3) Which treatment should be administered? The new data identified concerning which patients to treat and the duration of treatment were consistent with the data presented in the initial report and did not modify the original recommendations from 1997. The new data available represent stronger evidence than those in the original report (Two good-quality meta-analyses published since 1997). A new guideline concerning patients who are 75 years old or more has been added. Concerning, the new evidence identified has modified the guidelines for the therapeutic schema to adopt from 1997. These modifications concern irinotecan, oxaliplatin, oral fluoropyrimidines and methotrexate. Treatment with irinotecan or oxaliplatin associated with continuous 5FU infusion, modulated with folinic acid (LV5FU2-like) has become a standard. The use of oral fluoropyrimidines has become an option for patients who refuse hospitalisation or treatment by infusion. The use of methotrexate combined with 5FU is no longer recommended.
