IntroductionThis study describes treatment and retreatment patterns and outcomes in patients in France following nivolumab as a second-line or later (2L+) treatment in locally advanced or metastatic non-small cell lung cancer (LAM NSCLC).Materials and methodsThis analysis included adults with tumor, node, metastasis stage IIIB–IV NSCLC (as defined in the 7th or 8th edition American Joint Committee on Cancer/Union for International Cancer Control) treated with nivolumab monotherapy in 2L+ using data from the retrospective Epidemiological-Strategy and Medical Economics Lung Cancer database. The inclusion period was from January 1, 2015, to September 30, 2020, with a follow-up until September 30, 2021. Analyses were stratified according to the duration of index nivolumab treatment and tumor programmed death ligand 1 expression levels.ResultsIn total, the study included 4,001 patients (68% male; mean age [standard deviation] at index date, 63.6 [9.7] years) with a median follow-up of 34.3 months. The median nivolumab duration was 2.5 months (interquartile range, 1.4–6.3). The median overall survival (OS) from nivolumab initiation was 10.2 months (95% confidence interval [CI], 9.6–10.8). The median real-world progression-free survival and time to treatment discontinuation or death (95% CI) were 2.2 (2.1–2.3) and 2.7 (2.5–2.8) months, respectively. In total, 2,985 (74.6%) patients discontinued index nivolumab treatment: 226 (7.6% of discontinuers) received a further immune checkpoint inhibitor (ICI; 12.3% of discontinuers receiving further systemic treatment), and 1,604 (53.7%) received chemotherapy and/or targeted therapy. The proportion of ICI-retreated patients was the highest among those with the longest index treatment duration (15.8% among discontinuers receiving ≥26 weeks’ index nivolumab). The median OS from retreatment was longer in the resumption (ICI restart without another therapy for ≥6 weeks) compared with the rechallenge (ICI restart following non-ICI therapy) patient subgroup.ConclusionFew patients with LAM NSCLC in France received ICI retreatment following index nivolumab discontinuation, but the proportion increased with a longer duration of index nivolumab.

Background: Malignant pleural mesothelioma (MPM) is a rare thoracic malignancy with poor prognosis and limited treatment options. Immunotherapy shows potential for improved outcomes; however, real-world evidence on its use will take time to accumulate. This study examined patient characteristics, treatment patterns, overall survival (OS), and predictors of mortality among patients diagnosed with MPM in Denmark prior to the introduction of newer treatments. Methods: This historical cohort study based on routinely collected Danish National Registry data included adults newly diagnosed with MPM between 01 January 2011 and 31 May 2018. Summary statistics were used to describe patient characteristics and initial treatment. OS was estimated using Kaplan-Meier methods; Cox regression was used to compare patient mortality against the (age/sex-matched) general population and to investigate mortality predictors. Results: Overall, 880 patients were included; 44% had advanced MPM, 37% had non-advanced MPM, and 19% had unknown MPM stage. Median age at diagnosis was 71.9 years, and 82% of the patients were male. Within 180 days of diagnosis, no treatment was recorded for 215 patients (54%) with advanced MPM and 150 (46%) with non-advanced MPM. Median time-to-initial treatment (interquartile range) was 47 days (31–111) overall, 40 days (28–77) in patients with advanced MPM, and 53 days (35–121) with non-advanced MPM. Median OS was 13.7 months overall (non-advanced MPM: 18.0 months vs. advanced MPM: 10.0 months). Predictors of higher mortality were older age at diagnosis, histology, and advanced MPM stage. Interpretation: These findings provide a baseline upon which to evaluate MPM epidemiology as newer treatments are adopted in routine practice.

Abstract Background Precise data about ATTR-CM incidence rates at national level are scarce. Consequently, this study aimed to estimate the annual incidence and survival of transthyretin amyloid cardiomyopathy (ATTR-CM) in France between 2011 and 2019 using real world data. We used the French nationwide exhaustive data (SNDS database) gathering in- and out-patient claims. As there is no specific ICD-10 marker code for ATTR-CM, diagnosis required both amyloidosis (identified by E85. ICD-10 code or a tafamidis meglumine delivery) and a cardiovascular condition (identified by ICD-10 or medical procedure codes related to either heart failure, arrhythmias, conduction disorders or cardiomyopathies), not necessarily reported at the same visit. Patients with probable AL-form of amyloidosis or probable AA-form of amyloidosis were excluded. Results Between 2011 and 2019, 8,950 patients with incident ATTR-CM were identified. Incidence rates increased from 0.6 / 100,000 person-years in 2011 to 3.6 / 100,000 person-years in 2019 (p
