In patients with a progressive interstitial lung disease, 62% of whom had a CT pattern of usual interstitial pneumonia, those who received nintedanib had a lower annual rate of decline in the forced vital capacity than those who received placebo at 52 weeks.

In this randomized, placebo-controlled trial, treatment with nintedanib, an intracellular inhibitor of multiple tyrosine kinases, led to a reduced rate of loss of forced vital capacity in patients with idiopathic pulmonary fibrosis. Idiopathic pulmonary fibrosis is a fatal lung disease characterized by worsening dyspnea and progressive loss of lung function. 1 A decline in forced vital capacity (FVC) is consistent with disease progression and is predictive of reduced survival time. 1 – 6 Idiopathic pulmonary fibrosis is believed to arise from an aberrant proliferation of fibrous tissue and tissue remodeling due to the abnormal function and signaling of alveolar epithelial cells and interstitial fibroblasts. 7 The activation of cell-signaling pathways through tyrosine kinases such as vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), and platelet-derived growth factor (PDGF) has been implicated in the pathogenesis of . . .

Patients with autoimmune pulmonary alveolar proteinosis received inhaled molgramostim or matching placebo for 24 weeks. Patients receiving molgramostim had greater improvement in pulmonary gas transfer and alleviation of symptoms than those receiving placebo.

In patients with autoimmune pulmonary alveolar proteinosis, the use of inhaled recombinant granulocyte–macrophage colony-stimulating factor resulted in a significantly better alveolar–arterial oxygen gradient at 25 weeks than the use of placebo. The beneficial effect was not observed in smokers.

This document provides clinical recommendations for the diagnosis of idiopathic pulmonary fibrosis (IPF). It represents a collaborative effort between the American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society. The evidence syntheses were discussed and recommendations formulated by a multidisciplinary committee of IPF experts. The evidence was appraised and recommendations were formulated, written, and graded using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The guideline panel updated the diagnostic criteria for IPF. Previously defined patterns of usual interstitial pneumonia (UIP) were refined to patterns of UIP, probable UIP, indeterminate, and alternate diagnosis. For patients with newly detected interstitial lung disease (ILD) who have a high-resolution computed tomography scan pattern of probable UIP, indeterminate, or an alternative diagnosis, conditional recommendations were made for performing BAL and surgical lung biopsy; because of lack of evidence, no recommendation was made for or against performing transbronchial lung biopsy or lung cryobiopsy. In contrast, for patients with newly detected ILD who have a high-resolution computed tomography scan pattern of UIP, strong recommendations were made against performing surgical lung biopsy, transbronchial lung biopsy, and lung cryobiopsy, and a conditional recommendation was made against performing BAL. Additional recommendations included a conditional recommendation for multidisciplinary discussion and a strong recommendation against measurement of serum biomarkers for the sole purpose of distinguishing IPF from other ILDs. The guideline panel provided recommendations related to the diagnosis of IPF.

In the two replicate, placebo-controlled, 52-week, phase III INPULSIS trials, nintedanib 150 mg twice daily significantly reduced the annual rate of decline in FVC, the primary endpoint, in subjects with idiopathic pulmonary fibrosis (IPF). It is unknown if this effect was uniform across all subjects treated with nintedanib. To investigate the potential association of demographic and clinical variables with the effect of nintedanib in subjects with IPF. Subgroup analyses of pooled data from the INPULSIS trials were prespecified. Subgroups were analyzed by sex, age (<65, ≥65 yr), race (white, Asian), baseline FVC percentage predicted (≤70%, >70%), baseline St. George's Respiratory Questionnaire (SGRQ) total score (≤40, >40), smoking status (never, ex/current), systemic corticosteroid use (yes/no), and bronchodilator use (yes/no). A total of 1,061 subjects were treated (nintedanib n = 638, placebo n = 423). There was no statistically significant difference in the effect of nintedanib for the primary endpoint or the key secondary endpoints of change from baseline in SGRQ total score or time to first acute exacerbation in any subgroup. Treatment effects for the key secondary endpoints seemed more pronounced in subjects with baseline FVC ≤70% predicted, because the majority of acute exacerbations and a greater deterioration in SGRQ total score occurred in placebo-treated subjects in this subgroup. Pooled data from the INPULSIS trials support a consistent effect of nintedanib across a range of IPF phenotypes by slowing disease progression across a number of prespecified subgroups.

Idiopathic pulmonary fibrosis is an incurable disease of unknown etiology. Acute exacerbation of idiopathic pulmonary fibrosis is associated with high mortality. Excessive apoptosis of lung epithelial cells occurs in pulmonary fibrosis acute exacerbation. We recently identified corisin, a proapoptotic peptide that triggers acute exacerbation of pulmonary fibrosis. Here, we provide insights into the mechanism underlying the processing and release of corisin. Furthermore, we demonstrate that an anticorisin monoclonal antibody ameliorates lung fibrosis by significantly inhibiting acute exacerbation in the human transforming growth factorβ1 model and acute lung injury in the bleomycin model. By investigating the impact of the anticorisin monoclonal antibody in a general model of acute lung injury, we further unravel the potential of corisin to impact such diseases. These results underscore the role of corisin in the pathogenesis of acute exacerbation of pulmonary fibrosis and acute lung injury and provide a novel approach to treating this incurable disease. Here, the authors show that treatment with a monoclonal neutralizing antibody against the lung microbiota-derived proapoptotic peptide corisin ameliorates acute exacerbation of pulmonary fibrosis and severity of endotoxin-induced acute lung injury in mice.

In 2002 the American Thoracic Society/European Respiratory Society (ATS/ERS) classification of idiopathic interstitial pneumonias (IIPs) defined seven specific entities, and provided standardized terminology and diagnostic criteria. In addition, the historical \"gold standard\" of histologic diagnosis was replaced by a multidisciplinary approach. Since 2002 many publications have provided new information about IIPs. The objective of this statement is to update the 2002 ATS/ERS classification of IIPs. An international multidisciplinary panel was formed and developed key questions that were addressed through a review of the literature published between 2000 and 2011. Substantial progress has been made in IIPs since the previous classification. Nonspecific interstitial pneumonia is now better defined. Respiratory bronchiolitis-interstitial lung disease is now commonly diagnosed without surgical biopsy. The clinical course of idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia is recognized to be heterogeneous. Acute exacerbation of IIPs is now well defined. A substantial percentage of patients with IIP are difficult to classify, often due to mixed patterns of lung injury. A classification based on observed disease behavior is proposed for patients who are difficult to classify or for entities with heterogeneity in clinical course. A group of rare entities, including pleuroparenchymal fibroelastosis and rare histologic patterns, is introduced. The rapidly evolving field of molecular markers is reviewed with the intent of promoting additional investigations that may help in determining diagnosis, and potentially prognosis and treatment. This update is a supplement to the previous 2002 IIP classification document. It outlines advances in the past decade and potential areas for future investigation.

Recommendations regarding key aspects related to the diagnosis and pharmacological treatment of lymphangioleiomyomatosis (LAM) were recently published. We now provide additional recommendations regarding four specific questions related to the diagnosis of LAM and management of pneumothoraces in patients with LAM. Systematic reviews were performed and then discussed by a multidisciplinary panel. For each intervention, the panel considered its confidence in the estimated effects, the balance of desirable (i.e., benefits) and undesirable (i.e., harms and burdens) consequences, patient values and preferences, cost, and feasibility. Evidence-based recommendations were then formulated, written, and graded using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. For women who have cystic changes on high-resolution computed tomography of the chest characteristic of LAM, but who have no additional confirmatory features of LAM (i.e., clinical, radiologic, or serologic), the guideline panel made conditional recommendations against making a clinical diagnosis of LAM on the basis of the high-resolution computed tomography findings alone and for considering transbronchial lung biopsy as a diagnostic tool. The guideline panel also made conditional recommendations for offering pleurodesis after an initial pneumothorax rather than postponing the procedure until the first recurrence and against pleurodesis being used as a reason to exclude patients from lung transplantation. Evidence-based recommendations for the diagnosis and treatment of patients with LAM are provided. Frequent reassessment and updating will be needed.

IntroductionNintedanib slows disease progression in patients with idiopathic pulmonary fibrosis (IPF) by reducing the rate of decline in forced vital capacity, with an adverse event profile that is manageable for most patients. We used data from six clinical trials to characterise the safety and tolerability profile of nintedanib and to investigate its effects on survival.MethodsData from patients treated with ≥1 dose of nintedanib 150 mg two times per day or placebo in the 52-week TOMORROW trial and/or its open-label extension; the two 52-week INPULSIS trials and/or their open-label extension, INPULSIS-ON; and a Phase IIIb trial with a placebo-controlled period of ≥6 months followed by open-label nintedanib were pooled. All adverse events, irrespective of causality, were included in descriptive analyses. Parametric survival distributions were fit to pooled Kaplan-Meier survival data from the trials and extrapolated to estimate long-term survival.ResultsThere were 1126 patients in the pooled nintedanib group and 565 patients in the pooled placebo group. The mean duration of nintedanib treatment was 28 months. No new safety signals were observed. Incidence rates of bleeding, liver enzyme elevations and cardiovascular events were consistent with those observed in the INPULSIS trials. Diarrhoea was reported at a lower event rate in the pooled nintedanib group than in nintedanib-treated patients in the INPULSIS trials (76.5 vs 112.6 events per 100 patient exposure-years) and infrequently led to permanent treatment discontinuation (3.6 events per 100 patient exposure-years). Based on the Weibull distribution, mean (95% CI) survival was estimated as 11.6 (9.6, 14.1) years in nintedanib-treated patients and 3.7 (2.5, 5.4) years in placebo-treated patients.ConclusionsBased on pooled data from six clinical trials, the adverse event profile of nintedanib was manageable for most patients. Exploratory analyses based on extrapolation of survival data suggest that nintedanib extends life expectancy in patients with IPF.
