Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by the aberrant accumulation of extracellular matrix in the lungs. nintedanib is one of the two FDA-approved drugs for IPF treatment; however, the exact pathophysiological mechanisms of fibrosis progression and response to therapy are still poorly understood. In this work, the molecular fingerprint of fibrosis progression and response to nintedanib treatment have been investigated by mass spectrometry-based bottom-up proteomics in paraffin-embedded lung tissues from bleomycin-induced (BLM) pulmonary fibrosis mice. Our proteomics results unveiled that (i) samples clustered depending on the tissue fibrotic grade (mild, moderate, and severe) and not on the time course after BLM treatment; (ii) the dysregulation of different pathways involved in fibrosis progression such as the complement coagulation cascades, advanced glycation end products (AGEs) and their receptors (RAGEs) signaling, the extracellular matrix-receptor interaction, the regulation of actin cytoskeleton, and ribosomes; (iii) Coronin 1A (Coro1a) as the protein with the highest correlation when evaluating the progression of fibrosis, with an increased expression from mild to severe fibrosis; and (iv) a total of 10 differentially expressed proteins (padj-value ≤ 0.05 and Fold change ≤−1.5 or ≥1.5), whose abundance varied in the base of the severity of fibrosis (mild and moderate), were modulated by the antifibrotic treatment with nintedanib, reverting their trend. Notably, nintedanib significantly restored lactate dehydrogenase B (Ldhb) expression but not lactate dehydrogenase A (Ldha). Notwithstanding the need for further investigations to validate the roles of both Coro1a and Ldhb, our findings provide an extensive proteomic characterization with a strong relationship with histomorphometric measurements. These results unveil some biological processes in pulmonary fibrosis and drug-mediated fibrosis therapy.

Lineage dedifferentiation toward a mesenchymal-like state displaying myofibroblast and fibrotic features is a common mechanism of adaptive and acquired resistance to targeted therapy in melanoma. Here, we show that the anti-fibrotic drug nintedanib is active to normalize the fibrous ECM network, enhance the efficacy of MAPK-targeted therapy, and delay tumor relapse in a preclinical model of melanoma. Acquisition of this resistant phenotype and its reversion by nintedanib pointed to miR-143/-145 pro-fibrotic cluster as a driver of this mesenchymal-like phenotype. Upregulation of the miR-143/-145 cluster under BRAFi/MAPKi therapy was observed in melanoma cells in vitro and in vivo and was associated with an invasive/undifferentiated profile. The 2 mature miRNAs generated from this cluster, miR-143-3p and miR-145-5p, collaborated to mediate transition toward a drug-resistant undifferentiated mesenchymal-like state by targeting Fascin actin-bundling protein 1 (FSCN1), modulating the dynamic crosstalk between the actin cytoskeleton and the ECM through the regulation of focal adhesion dynamics and mechanotransduction pathways. Our study brings insights into a novel miRNA-mediated regulatory network that contributes to non-genetic adaptive drug resistance and provides proof of principle that preventing MAPKi-induced pro-fibrotic stromal response is a viable therapeutic opportunity for patients on targeted therapy.

OBJECTIVE: The aim of these analyses was to investigate the rate of decline in forced vital capacity (FVC) in patients with SSc-associated interstitial lung disease (SSc-ILD) with and without cough or dyspnoea in the SENSCIS trial. METHODS: Patients in the SENSCIS trial were randomized to receive nintedanib or placebo. Subgroups with and without cough or dyspnoea at baseline were defined by responses to the St Georges Respiratory Questionnaire. RESULTS: At baseline, 114/575 patients (19.8%) did not have cough and 172/574 patients (30.0%) did not have dyspnoea. In the placebo group, the rate of FVC decline over 52 weeks was similar in patients with and without cough (-95.6 and -83.4 mL/year, respectively) or dyspnoea (-95.8 and -87.7 mL/year, respectively). The effect of nintedanib vs placebo on reducing the rate of FVC decline was numerically more pronounced in patients without than with cough [difference: 74.4 (95% CI -11.1, 159.8) vs 31.5 (-11.1, 74.1)] and without than with dyspnoea [79.8 (9.8, 149.7) vs 25.7 (-19.9, 71.3)], but interaction P-values did not indicate heterogeneity in the treatment effect between these subgroups (P = 0.38 and P = 0.20, respectively). CONCLUSION: In the placebo group of the SENSCIS trial, the rate of FVC decline was similar irrespective of the presence of cough or dyspnoea at baseline. The effect of nintedanib on reducing the rate of FVC decline was numerically more pronounced in patients without than with cough or dyspnoea at baseline, but no statistically significant heterogeneity was observed between the subgroups.

Systemic sclerosis (SSc) is a rare, systemic autoimmune disease of unknown etiology. Among the systemic rheumatic diseases, SSc carries the highest mortality, in part due to the historical lack of disease modifying therapies. Recently, landmark randomized controlled trials (RCTs) have been conducted that have illustrated the heterogeneous nature of SSc and furthered our understanding of the key inflammatory and fibrotic pathways involved in SSc pathogenesis. Although SSc affects various organ systems, RCTs have focused on investigating treatments for diffuse cutaneous sclerosis (dcSSc) and interstitial lung disease (ILD). While recent RCTs for dcSSc have failed to demonstrate a treatment benefit, the outcomes of two RCTs led to the approval of two novel therapies for SSc-ILD: nintedanib and tocilizumab. This review summarizes the salient outcome data from recent SSc trials within a practical clinical framework and points out gaps in knowledge that may help inform the design of future SSc studies.

Background: Despite intensive risk-based treatment protocols, 15% of paediatric patients with B-Cell Precursor Acute Lymphoblastic Leukaemia (BCP-ALL) experience relapse. There is urgent need of novel strategies to target poor prognosis subgroups, like PAX5 translocated. Methods: We considered 289 childhood BCP-ALL cases consecutively enrolled in Italy in the AIEOP-BFM ALL2000/R2006 protocols and we performed extensive molecular profiling, integrating gene expression, copy number analyses and fusion genes discovery by target-capture NGS. We developed preclinical strategies to target PAX5 fusion genes. Findings: We identified 135 cases without recurrent genetic rearrangements. Among them, 59 patients (43·7%) had a Ph-like signature; the remaining cases were identified as ERG-related (26%), High-Hyperdiploid-like (17%), ETV6::RUNX1-like (8·9%), MEF2D-rearranged (2·2%) or KMT2A-like (1·5%). A poor prognosis was associated with the Ph-like signature, independently from other high-risk features. Interestingly, PAX5 was altered in 54·4% of Ph-like compared to 16·2% of non-Ph-like cases, with 7 patients carrying PAX5 fusions (PAX5t), involving either novel (ALDH18A1, IKZF1, CDH13) or known (FBRSL1, AUTS2, DACH2) partner genes. PAX5t cases have a specific driver activity signature, extending to multiple pathways including LCK hyperactivation. Among FDA-approved drugs and inhibitors, we selected Dasatinib, Bosutinib and Foretinib, in addition to Nintedanib, known to be LCK ligands. We demonstrated the efficacy of the LCK-inhibitor BIBF1120/Nintedanib, as single agent or in combination with conventional chemotherapy, both ex vivo and in patient-derived xenograft model, showing a synergistic effect with dexamethasone. Interpretation: This study provides new insights in high-risk Ph-like leukaemia and identifies a potential therapy for targeting PAX5-fusion poor risk group.

La fibrose pulmonaire idiopathique (FPI) est une maladie chronique, à progression lente, caractérisée par une rigidification du tissu pulmonaire. Cette maladie entraîne une défaillance des organes et la mort, avec une survie médiane de 3 à 5 ans suite au diagnostic. Environ 3 millions de personnes sont touchées dans le monde et l’incidence ainsi que la prévalence de cette pathologie semblent augmenter au fil des années. Il n’existe actuellement aucun traitement pharmacologique curatif de la FPI. De plus, les modèles d’études précliniques actuels ne récapitulent généralement pas la physiopathologie humaine, les rendant peu prédictifs du succès clinique des médicaments en développement pour cette maladie. Il existe donc un besoin urgent de développer de nouveaux modèles animaux afin d’améliorer la fiabilité des études précliniques et ainsi faciliter le processus de développement de nouveaux médicaments pour la FPI. Dans cette optique, nous avons développé un nouveau modèle in vivo utilisant des tissus provenant de patients atteints de FPI, ainsi que des cellules dérivées de ces tissus. Pour ce faire, des fragments de poumons ou des suspensions de fibroblastes FPI ont été implantés sur la membrane chorioallantoïdienne (CAM) d’embryons de poulets. Ces xénogreffes ont été cultivées pendant 7 jours sur la CAM, en présence ou non de traitements anti-fibrotiques. Nos résultats ont démontré que ces xénogreffes sont viables et prolifèrent sur la CAM et que les tissus cultivés conservent le phénotype FPI du tissu d’origine. De leur côté, les fibroblastes implantés semblent mimer des foyers fibroblastiques. Des traitements topiques quotidiens avec le nintedanib, une molécule actuellement approuvée pour le traitement de la FPI, ont mené à une diminution significative du volume, de l’expression de gènes associés à la fibrose (ACTA2, COL1A1 et CTGF), ainsi que des niveaux de collagènes des xénogreffes. Des modulations significatives ont aussi été observées avec le PBI-4050, un méd, Idiopathic pulmonary fibrosis (IPF) is a chronic and slowly progressive disease characterized by lung tissue stiffening. This disease leads organ failure and death, with a median survival of 3 to 5 years following diagnosis. Around 3 million people are affected worldwide, and the incidence and prevalence of this disease seems to be increasing over the years. There is currently no curative pharmacological treatment for IPF. Furthermore, current preclinical models fail to replicate the human pathophysiology and thus are poor predictors of the success or failure of clinical trials for drugs in development for this disease. There is therefore an urgent need to develop new animal models in order to improve the reliability of preclinical studies and thus facilitate the development of new drugs for IPF. In this regard, we have developed a novel in vivo model using tissue from IPF patients who have undergone lung transplantation, as well as cells derived from these tissues. To do so, lung fragments or IPF fibroblast suspensions were implanted on the chorioallantoic membrane (CAM) of chick embryos. These xenografts were cultivated for 7 days on the CAM, with or without antifibrotic treatments. Our results showed that these xenografts are viable and proliferate on the CAM, and that the tissue xenografts retain their IPF phenotype. For their part, the implanted fibroblasts appear to mimic fibroblastic foci. Daily topical treatments with nintedanib, a molecule currently approved for the treatment of IPF, led to a significant decrease in volume, expression of fibrosis-associated genes (ACTA2, COL1A1 and CTGF), and collagen levels in xenografts. Significant modulations were also observed with PBI-4050, a drug candidate in development for IPF, as well as with compounds that target the immune microenvironment, GLPG1205 and fenofibric acid. Altogether, these results demonstrate the versatility of the CAM-IPF model to test the efficacy of different therapeutic strategies re

A novel synthetic approach involving an Eschenmoser coupling reaction of substituted 3-bromooxindoles (H, 6-Cl, 6-COOMe, 5-NO2) with two substituted thiobenzanilides in dimethylformamide or acetonitrile was used for the synthesis of eight kinase inhibitors including Nintedanib and Hesperadin in yields exceeding 76%. Starting compounds for the synthesis are also easily available in good yields. 3-Bromooxindoles were prepared either from corresponding isatins using a three-step synthesis in an average overall yield of 65% or by direct bromination of oxindoles (yield of 65-86%).

Introduction: In recent decades, the primary focus of pharmaceutical research in interstitial lung diseases (ILD) has been on idiopathic pulmonary fibrosis (IPF). Recently, pharmaceutical development has also focused on other forms of ILDs, including connective tissue diseases associated ILD, fibrotic hypersensitivity pneumonitis, and sarcoidosis. Areas Covered: The authors summarize the advances in pharmacotherapy for the treatment of ILD. Specifically, the authors review the most recent studies and discuss the most recent research findings and future prospects. Expert opinion: Data collected over the past years have confirmed the efficacy of antifibrotic drugs on slowing disease progression in IPF. The usual strategy for CTD-ILD management is represented by the combined use of corticosteroids and immunosuppressive agents. There is an urgent need for new target therapies. The concept of progressive fibrosing ILD has emerged in the ILD community in recent years, which has led to grouping several diseases with a common disease behavior to find an effective treatment. At present, selecting the best therapy in ILDs should be reasonably performed on a case-by-case basis through a multidisciplinary team discussion in tertiary ILD centers, taking into consideration patients’ symptoms, lung functional trends, and radiological changes.

Background: The efficacy of nintedanib in progressive fibrosing interstitial lung diseases (ILDs) was demonstrated in the randomised, double-blind, placebo-controlled INBUILD trial. This subgroup analysis evaluated the efficacy and safety of nintedanib in the Japanese population. Methods: Patients with progressive fibrosing ILDs (evaluated by physicians within 24 months of screening) were randomised (1:1) to twice-daily 150-mg nintedanib or placebo; treatment continued until the last patient completed 52 weeks. The primary endpoint was the annual rate of decline in forced vital capacity (FVC) over 52 weeks. Time-to-first acute ILD exacerbation or death and time-to-death up until the last patient had completed the week 52 visit were evaluated. This subgroup analysis included 108 Japanese patients. Results: The adjusted annual rates of FVC decline (mL/year) over 52 weeks for Japanese patients were −148.31 (nintedanib) and −240.36 (placebo), adjusted difference: 92.05 (95% CI: −10.69–194.80) and for non-Japanese patients were −67.41 (nintedanib) and −177.65 (placebo), adjusted difference: 110.24 (95% CI: 64.97–155.52). No heterogeneity in treatment effect between Japanese and non-Japanese subgroups was observed (treatment-by-subgroup interaction, p = 0.75). The risks of “acute exacerbation or death” (hazard ratio, 0.30 [95% CI: 0.10–0.91]) and mortality (hazard ratio, 0.54 [95% CI: 0.14–2.11]) in Japanese patients were numerically lower for nintedanib than placebo. There were no new or unexpected safety findings. Conclusions: In Japanese patients, nintedanib slowed ILD progression, evidenced by a reduction in the annual rate of decline in FVC vs placebo. The efficacy and safety of nintedanib in Japanese patients were consistent with the overall INBUILD population.

Nonidiopathic pulmonary fibrosis (non-IPF) progressive fibrotic interstitial lung diseases (PF-ILDs) are a heterogeneous group of ILDs, often challenging to diagnose, although an accurate diagnosis has significant implications for both treatment and prognosis. A subgroup of these patients experiences progressive deterioration in lung function, physical performance, and quality of life after conventional therapy. Risk factors for ILD progression include older age, lower baseline pulmonary function, and a usual interstitial pneumonia pattern. Management of non-IPF P-ILD is both pharmacologic and nonpharmacologic. Antifibrotic drugs, originally approved for IPF, have been considered in patients with other fibrotic ILD subtypes, with favorable results in clinical trials.

Background: FIBRONET was an observational, multicentre, prospective cohort study investigating the baseline characteristics, clinical course of disease and use of antifibrotic treatment in Italian patients with idiopathic pulmonary fibrosis (IPF). Methods: Patients aged ≥ 40 years diagnosed with IPF within the previous 3 months at 20 Italian centres were consecutively enrolled and followed up for 12 months, with evaluations at 3, 6, 9 and 12 months. The primary objective was to describe the clinical course of IPF over 12 months of follow-up, including changes in lung function measured by % predicted forced vital capacity (FVC% predicted). Results: 209 patients (82.3% male, mean age 69.54 ± 7.43 years) were enrolled. Mean FVC% predicted was relatively preserved at baseline (80.01%). The mean time between IPF diagnosis and initiation of antifibrotic therapy was 6.38 weeks; 72.3% of patients received antifibrotic therapy within the first 3 months of follow-up, and 83.9% within 12 months of follow-up. Mean FVC% predicted was 80.0% at baseline and 82.2% at 12 months, and 47.4% of patients remained stable (i.e. had no disease progression) in terms of FVC% predicted during the study. Conclusions: FIBRONET is the first prospective, real-life, observational study of patients with IPF in Italy. The short time between diagnosis and initiation of antifibrotic therapy, and the stable lung function between baseline and 12 months, suggest that early diagnosis and prompt initiation of antifibrotic therapy may preserve lung function in patients with IPF.

The primary analysis of the INBUILD trial showed that in subjects with progressive fibrosing interstitial lung diseases (ILDs), nintedanib slowed the decline in forced vital capacity (FVC) over 52 weeks. We report the effects of nintedanib on ILD progression over the whole trial.Subjects with fibrosing ILDs other than idiopathic pulmonary fibrosis, who had ILD progression within the 24 months before screening despite management deemed appropriate in clinical practice, were randomised to receive nintedanib or placebo. Subjects continued on blinded randomised treatment until all subjects had completed the trial. Over the whole trial, mean (sd) exposure to trial medication was 15.6 (7.2) and 16.8 (5.8) months in the nintedanib and placebo groups, respectively.In the nintedanib (n=332) and placebo (n=331) groups, respectively, the proportions of subjects who had ILD progression (absolute decline in FVC ≥10% predicted) or died were 40.4% and 54.7% in the overall population (HR 0.66 [95% CI: 0.53, 0.83]; p=0.0003), and 43.7% and 55.8% among subjects with a usual interstitial pneumonia (UIP)-like fibrotic pattern on high-resolution computed tomography (HRCT) (HR 0.69 [0.53, 0.91]; p=0.009). In the nintedanib and placebo groups, respectively, the proportions who had an acute exacerbation of ILD or died were 13.9% and 19.6% in the overall population (HR 0.67 [95% CI: 0.46, 0.98]; p=0.04), and 15.0% and 22.8% among subjects with a UIP-like fibrotic pattern on HRCT (HR 0.62 [0.39, 0.97]; p=0.03).Based on data from the whole INBUILD trial, nintedanib reduced the risk of events indicating ILD progression.

Introduction The approval of antifibrotic agents nintedanib and pirfenidone revolutionized the management of idiopathic pulmonary fibrosis (IPF). These treatments showed acceptable tolerability in randomized-clinical trials; however, they have been associated with a spectrum of potential side effects which require careful assessment of risks and benefits in the individual patient before commencing and during antifibrotic therapy. Areas covered The accrued evidence on safety of nintedanib and pirfenidone is summarized, from the first randomized clinical trials to the open-label extension studies and post-marketing clinical experiences which helped clarify the long-term tolerability of these drugs. Expert opinion The data collected over the last years confirmed the comparable tolerability profile of nintedanib and pirfenidone. The physician's assessment of expected side effects may help decide the optimal first-line therapy for the individual patient. Patient's counseling during treatment remains essential to manage emerging adverse events and eventually inform the decision of drug discontinuation.

Introduction: The last two decades witnessed an increasing number of well-designed late phase trials in patients with Idiopathic Pulmonary Fibrosis (IPF), leading to the approval of the first effective therapies for these patients, pirfenidone and nintedanib. Currently, novel putative agents for the treatment of IPF are being tested in phase III trials, possibly marking a new breakthrough in IPF management. Areas covered: In this review, the available evidence on completed phase III trials in IPF is summarized, from the past failures of immunosuppressive and anti-inflammatory agents, anticoagulants and endothelin-receptor antagonists to the positive results of the antifibrotic treatments that revolutionized IPF therapeutic landscape. Literature search was performed using Medline and Clinicaltrials.org databases (1999–2020). Expert opinion: In the relatively young history of pharmaceutical research in IPF, most phase III trials provided disappointing results, however the lessons learned helped paving the way to the success of the first therapies capable of modifying the natural history of this deadly disease. To date, the conduction of robustly designed phase III trials on novel drugs remains crucial to pursue the goal of halting disease progression in these patients, using a therapeutic approach that should become more and more tailored to the individual.

AGO-OVAR 12 investigated the effect of adding the oral triple angiokinase inhibitor nintedanib to standard front-line chemotherapy for advanced ovarian cancer. At the primary analysis, nintedanib demonstrated significantly improved progression-free survival (PFS; primary endpoint) compared with placebo. We report final results, including overall survival (OS). Patients with primary debulked International Federation of Gynaecology and Obstetrics (FIGO) stage IIB–IV newly diagnosed ovarian cancer were randomised 2:1 to receive carboplatin (area under the curve 5 or 6) plus paclitaxel (175 mg/m2) on day 1 every 3 weeks for six cycles combined with either nintedanib 200 mg or placebo twice daily on days 2–21 every 3 weeks for up to 120 weeks. Between December 2009 and July 2011, 1,366 patients were randomised (911 to nintedanib, 455 to placebo). Disease was considered as high risk (FIGO stage III with >1 cm residuum, or any stage IV) in 39%. At the final analysis, 605 patients (44%) had died. There was no difference in OS (hazard ratio 0.99, 95% confidence interval [CI] 0.83–1.17, p = 0.86; median 62.0 months with nintedanib vs. 62.8 months with placebo). Subgroup analyses according to stratification factors, clinical characteristics and risk status showed no OS difference between treatments. The previously reported PFS improvement seen with nintedanib did not translate into an OS benefit in the nonhigh-risk subgroup. Updated PFS results were consistent with the primary analysis (hazard ratio 0.86, 95% CI 0.75–0.98; p = 0.029) favouring nintedanib. The safety profile was consistent with previous reports.

Hypersensitivity Pneumonitis (HP) one of the most common interstitial lung diseases (ILDs) is characterized by exposure to an inhaled inciting antigen that leads to a host immunologic reaction determining interstitial inflammation and architectural distortion. The underlying pathogenetic mechanisms are unclear. The absence of international shared diagnostic guidelines and the lack of a "gold-standard" test for HP combined with the presence of several clinical and radiologic overlapping features makes it particularly challenging to differentiate HP from other ILDs, also in expert contests. Radiology is playing a more crucial role in this process; recently the headcheese sign was recognized as a more specific for chronic-HP than the extensive mosaic attenuation. Several classification proposals and diagnostic models have been advanced by different groups, with no prospective validation. Therapeutic options for HP have been limited to antigen avoidance and immunosuppressant drugs over the last decades. Several questions about this condition remain unanswered and there is a need for more studies.

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease that is, by definition, progressive. Progression of IPF is reflected by a decline in lung function, worsening of dyspnea and exercise capacity, and deterioration in health-related quality of life. In the short term, the course of disease for an individual patient is impossible to predict. A period of relative stability in forced vital capacity (FVC) does not mean that FVC will remain stable in the near future. Frequent monitoring using multiple assessments, not limited to pulmonary function tests, is important to evaluate disease progression in individual patients and ensure that patients are offered appropriate care. Optimal management of IPF requires a multidimensional approach, including both pharmacological therapy to slow decline in lung function and supportive care to preserve patients' quality of life.

BACKGROUND: Idiopathic Pulmonary Fibrosis (IPF) is an aggressive interstitial lung disease with an unpredictable course. Occupational dust exposure may contribute to IPF onset, but its impact on antifibrotic treatment and disease prognosis is still unknown. We evaluated clinical characteristics, respiratory function and prognostic predictors at diagnosis and at 12 month treatment of pirfenidone or nintedanib in IPF patients according to occupational dust exposure. METHODS: A total of 115 IPF patients were recruited. At diagnosis, we collected demographic, clinical characteristics, occupational history. Pulmonary function tests were performed and two prognostic indices [Gender, Age, Physiology (GAP) and Composite Physiologic Index (CPI)] calculated, both at diagnosis and after the 12 month treatment. The date of long-term oxygen therapy (LTOT) initiation was recorded during the entire follow-up (mean = 37.85, range 12-60 months). RESULTS: At baseline, patients exposed to occupational dust [≥ 10 years (n = 62)] showed a lower percentage of graduates (19.3% vs 54.7%; p = 0.04) and a higher percentage of asbestos exposure (46.8% vs 18.9%; p 0.002) than patients not exposed [< 10 years (n = 53)]. Both at diagnosis and after 12 months of antifibrotics, no significant differences for respiratory function and prognostic predictors were found. The multivariate analysis confirmed that occupational dust exposure did not affect neither FVC and DLCO after 12 month therapy nor the timing of LTOT initiation. CONCLUSION: Occupational dust exposure lasting 10 years or more does not seem to influence the therapeutic effects of antifibrotics and the prognostic predictors in patients with IPF.

The date of long-term oxygen therapy (LTOT) initiation was recorded during the entire follow-up (mean = 37.85, range 12-60 months). RESULTS: At baseline, patients exposed to occupational dust [≥ 10 years (n = 62)] showed a lower percentage of graduates (19.3% vs 54.7%; p = 0.04) and a higher percentage of asbestos exposure (46.8% vs 18.9%; p 0.002) than patients not exposed [< 10 years (n = 53)]. Both at diagnosis and after 12 months of antifibrotics, no significant differences for respiratory function and prognostic predictors were found. The multivariate analysis confirmed that occupational dust exposure did not affect neither FVC and DLCO after 12 month therapy nor the timing of LTOT initiation. CONCLUSION: Occupational dust exposure lasting 10 years or more does not seem to influence the therapeutic effects of antifibrotics and the prognostic predictors in patients with IPF.

Background: Real-life data on the use of pirfenidone and nintedanib to treat patients with idiopathic pulmonary fibrosis (IPF) are still scarce. Methods: We compared the efficacy of either pirfenidone (n = 78) or nintedanib (n = 28) delivered over a 24-month period in patients with IPF, followed at two regional clinic centers in Italy, with a group of patients who refused the treatment (n = 36), and who were considered to be controls. All patients completed regular visits at 1- to 3-month intervals, where primary [forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO)] and secondary outcomes (side effects, treatment compliance, and mortality) were recorded. Results: Over time, the decline in FVC and DLCO was significantly higher (p = 0.0053 and p = 0.037, respectively) in controls when compared with the combined treated group, with no significant difference between the two treated groups. Compared to patients with less advanced disease (GAP (Gender, Age, Physiology) stage I), those in GAP stages II and III showed a significantly higher decline in both FVC and DLCO irrespective of the drug taken. Side effects were similarly reported in patients receiving pirfenidone and nintedanib (5% and 7%, respectively), whereas mortality did not differ among the three groups. Conclusion: This real-life study demonstrated that both pirfenidone and nintedanib were equally effective in reducing the decline of FVC and DLCO versus non-treated patients after 24 months of treatment; however, patients with more advanced disease were likely to show a more rapid decline in respiratory function

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease that is, by definition, progressive. Progression of IPF is reflected by a decline in lung function, worsening of dyspnea and exercise capacity, and deterioration in health-related quality of life. In the short term, the course of disease for an individual patient is impossible to predict. A period of relative stability in forced vital capacity (FVC) does not mean that FVC will remain stable in the near future. Frequent monitoring using multiple assessments, not limited to pulmonary function tests, is important to evaluate disease progression in individual patients and ensure that patients are offered appropriate care. Optimal management of IPF requires a multidimensional approach, including both pharmacological therapy to slow decline in lung function and supportive care to preserve patients' quality of life., SCOPUS: ar.j, info:eu-repo/semantics/published

The last years have led to advances in the therapeutic management of idiopathic pulmonary fibrosis (IPF), mainly through the discovery of new pathological pathways and drugs and better design of clinical trials. The objective of this review is both to describe the current therapies approved for the treatment of IPF and the emerging therapeutic approaches. Currently, nintedanib and pirfenidone are the basis of IPF therapy, based on the results of large randomized clinical trials showing their safety and efficacy in reducing disease progression. Nonetheless, the ideal IPF therapy is still lacking and trials are underway to test new therapeutic targets. The near future could bring to clinicians and patients a combined therapeutic strategy, hitting the disease from several simultaneous pathways and hopefully leading to clinical stabilization or improvement.

Background: Given the broad definition of an acute exacerbation of IPF, it is likely that acute exacerbations are heterogeneous in their aetiology, severity and clinical course. We used pooled data from the INPULSIS® trials of nintedanib versus placebo to investigate whether acute exacerbations reported as serious adverse events were associated with higher mortality than those reported as non-serious adverse events and to assess the effect of nintedanib on these types of events. Methods: Adverse events considered by an investigator to be an acute exacerbation were adjudicated as a confirmed acute exacerbation, suspected acute exacerbation, or not an acute exacerbation. Time to first investigator-reported acute exacerbation or confirmed/suspected acute exacerbation reported as a serious adverse event or non-serious adverse event over the 52-week treatment period was assessed post-hoc. Deaths were assessed based on data collected over the 52-week treatment period. Results: Of 63 patients who had ≥1 investigator-reported acute exacerbation, 48 (76.2%) had a first acute exacerbation reported as a serious adverse event. Thirty-six (3.4%) patients had ≥1 confirmed/suspected acute exacerbation, of whom 31 had a first event reported as a serious adverse event. Investigator-reported acute exacerbations reported as serious adverse events occurred in 23 patients in the nintedanib group and 26 in the placebo group. Confirmed/suspected acute exacerbations reported as serious adverse events occurred in 10 and 21 patients in these groups, respectively. Nintedanib significantly reduced the risk of a first acute exacerbation reported as a serious adverse event (HR 0.57 [95% CI: 0.32, 0.99]; p = 0.0476) and the risk of a first confirmed/suspected acute exacerbation reported as a serious adverse event (HR 0.30 [95% CI: 0.14, 0.64]; p = 0.0019) versus placebo. A higher proportion of patients with investigator-reported acute exacerbations reported as serious adverse events died than pat

AGO-OVAR 12 investigated the effect of adding the oral triple angiokinase inhibitor nintedanib to standard front-line chemotherapy for advanced ovarian cancer. At the primary analysis, nintedanib demonstrated significantly improved progression-free survival (PFS; primary end point) compared with placebo. We report final results, including overall survival (OS). Patients with primary debulked International Federation of Gynecology and Obstetrics (FIGO) stage IIB-IV newly diagnosed ovarian cancer were randomised 2:1 to receive carboplatin (area under the curve 5 or 6) plus paclitaxel (175 mg/m2 ) on day 1 every 3 weeks for six cycles combined with either nintedanib 200 mg or placebo twice daily on days 2-21 every 3 weeks for up to 120 weeks. Between December 2009 and July 2011, 1366 patients were randomised (911 to nintedanib, 455 to placebo). Disease was considered as high risk (FIGO stage III with >1 cm residuum, or any stage IV) in 39%. At the final analysis, 605 patients (44%) had died. There was no difference in OS (hazard ratio 0.99, 95% confidence interval [CI] 0.83-1.17, p = 0.86; median 62.0 months with nintedanib versus 62.8 months with placebo). Subgroup analyses according to stratification factors, clinical characteristics and risk status showed no OS difference between treatments. The previously reported PFS improvement seen with nintedanib did not translate into an OS benefit in the non-high-risk subgroup. Updated PFS results were consistent with the primary analysis (hazard ratio 0.86, 95% CI 0.75-0.98; p = 0.029) favouring nintedanib. The safety profile was consistent with previous reports.

Background: Idiopathic pulmonary fibrosis (IPF) is characterized by a progressive and irreversible respiratory failure. Non-invasive markers of disease activity are essential for prognosis and evaluation of early response to anti-fibrotic treatments. Objectives: The aims of this study were to determine whether fluorodeoxyglucose ([18F]-FDG) lung uptake is reduced after initiation of pirfenidone or nintedanib and to assess its possible use as a prognostic factor. Methods: [18F]-FDG PET/CT was performed in IPF patients and in a murine model of pulmonary fibrosis. PET/CTs were performed at day 8 and day 15 post-instillation of bleomycin in pirfenidone- or vehicule-treated mice. In IPF patients, PET-CT was performed before and 3 months after the initiation of pirfenidone or nintedanib. Results: In bleomycin-treated mice, pirfenidone significantly reduced the [18F]-FDG uptake compared to vehicule-treated mice at day 15 (p < 0.001), whereas no difference was observed at day 8 after bleomycin administration. In IPF patients, [18F]-FDG lung uptake before and after 3 months of treatment by nintedanib (n = 11) or pirfenidone (n = 14) showed no significant difference regardless the antifibrotic treatment. Moreover, no difference was noticed between patients with progressive or non-progressive disease at one year of follow up. Conclusions: Pirfenidone significantly reduces the lung [18F]-FDG uptake during the fibrotic phase in a mouse model of IPF. However, these preclinical data were not confirmed in IPF patients 3 months after the initiation of antifibrotic therapy. [18F]-FDG seems therefore not useful in clinical practice to assess the early response of IPF patients to nintedanib or pirfenidone., SCOPUS: ar.j, info:eu-repo/semantics/published

Background: Two therapeutic options are currently available for patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF): pirfenidone and nintedanib. To date, there is still insufficient data on the efficacy of these 2 agents in patients with more severe disease. Objectives: This national, multicenter, retrospective real-life study was intended to determine the impact of nintedanib on the treatment of patients with severe IPF. Methods: All patients included had severe IPF and had to have at least 6 months of follow-up before and at least 6 months of follow-up after starting nintedanib. The aim of the study was to compare the decline in lung function before and after treatment. Patient survival after 6 months of therapy with nintedanib was assessed. Results: Forty-one patients with a forced vital capacity (FVC) ≤50% and/or a diffusing capacity of the lung for carbon monoxide (DLCO) ≤35% predicted at the start of nintedanib treatment were enrolled. At the 6-month follow-up, the decline of DLCO (both absolute and % predicted) was significantly reduced compared to the pretreatment period (absolute DLCO at the -6-month, T0, and +6-month time points (5.48, 4.50, and 5.03 mmol/min/kPa, respectively, p = 0.03; DLCO% predicted was 32.73, 26.54, and 29.23%, respectively, p = 0.04). No significant beneficial effect was observed in the other functional parameters analyzed. The 1-year survival in this population was 79%, calculated from month 6 of therapy with nintedanib. Conclusions: This nationwide multicenter experience in patients with severe IPF shows that nintedanib slows down the rate of decline of absolute and % predicted DLCO but does not have significant impact on FVC or other lung parameters.

Background: Idiopathic pulmonary fibrosis (IPF) is characterized by progressive loss of lung function with high mortality within the first 5 years from diagnosis. In 2011–2014, two drugs, pirfenidone and nintedanib, have been approved worldwide for prevention of IPF progression. National IPF-registries have been established in both Finland and Sweden. Our study explored potential differences in the care of IPF in these two countries. Methods: Patients included consecutively in the Finnish and Swedish IPF-registries from January 1, 2014 through December 31, 2016 were included in the study. Data on demographics and lung function at the time of inclusion were collected. Access to antifibrotic drugs and data on disease outcomes, mortality and the proportion of patients who underwent lung transplantation, was collected during a 3-year follow up. Results: One-hundred and fifty-two patients from the Finnish and 160 patients from the Swedish IPF-cohorts were included in the study. At inclusion, Finnish patients were significantly older than the Swedish patients (74.6 years vs 72.5 years, p = 0.017). The proportion of non-smokers was significantly higher in the Finnish cohort (41.7% vs 26.9%, p = 0.007). Forced vital capacity (FVC), % of predicted (78.2 vs 71.7 for Finnish and Swedish patients, respectively, p = 0.01) and diffusion capacity for carbon monoxide (DLCO), % of predicted (53.3 vs 48.2 for Finnish and Swedish patients, respectively, p = 0.002) were significantly higher in the Finnish cohort compared to the Swedish cohort at the time of inclusion. During the 3-year follow up period, 45 (29.6%) Finnish and 111 (69.4%) Swedish patients, respectively, were initiated on treatment with an antifibrotic drug (pirfenidone or nintedanib) (p < 0.001). When comparing possible determinants of treatment, patients with higher FVC % were less likely to start antifibrotic drugs (OR 0.96, 95%CI 0.93–1.00, p < 0.024). To be resident in Sweden was the main determinan

Idiopathic pulmonary fibrosis (IPF) is a relentlessly progressive and inevitably fatal lung disease. Although the etiology and pathogenesis of IPF remain incompletely understood, two drugs (e.g., pirfenidone and nintedanib) have proven effective in slowing down functional decline and disease progression and are now approved worldwide for treatment. Yet, as outlined by the recent guideline document on treatment of IPF, every therapeutic decision needs to be tailored to the individual patient, after discussing potential benefits and pitfalls. Comorbidities, which almost invariably complicate IPF, impact significantly clinical course and prognosis of the disease, making a holistic approach to the best care for these patients. Randomized-controlled trials remain a valid choice for selected IPF patients and their completion is critically important to achieving the ultimate goal of improving both survival and quality of life of patients suffering from this devastating disease.

La Fibrosis Pulmonar Idiopática (FPI) es una forma específica de neumonía intersticial fibrosante crónica, limitada a los pulmones. Actualmente hay dos fármacos autorizados para su tratamiento: nintedanib y pirfenidona. El principal objetivo del trabajo es evaluar la efectividad de ambos fármacos, y como objetivos secundarios, la evaluación de la adecuación de la prescripción y la seguridad. Para ello, se ha llevado a cabo un estudio observacional retrospectivo, incluyéndose todos los pacientes diagnosticados de FPI tratados con pirfenidona y nintedanib en el Hospital de Valme. Los datos se han obtenido de la historia clínica digital. Se incluyeron un total de 17 pacientes, ocho de ellos tratados con pirfenidona y nueve de ellos con nintedanib. Entre los pacientes con tratamiento antifibrótico por FPI, se observa que el perfil más abundante es el de hombre de edad avanzada, no fumador y con disnea de esfuerzo. En cuanto a la adecuación de la prescripción de pirfenidona, tres de los ocho pacientes en tratamiento cumplían todos los criterios de prescripción en base a la Guía Farmacoterapéutica del hospital (GFT). Y en el caso del nintedanib, de los nueve pacientes tratados, cinco cumplían todos los criterios de prescripción, en base al Informe de Posicionamiento Terapéutico (IPT). Así, la adecuación a la prescripción es aceptable. Ambos fármacos presentan una efectividad moderada en base a la variable espirométrica (Capacidad Vital Forzada o CVF), lo cual se ha observado realizando 3 mediciones, a los tres, seis y dice meses desde el inicio del tratamiento. En dichas mediciones se valoraba si el paciente presentaba o no una reducción de la CVF mayor del 10%. Los resultados muestran que algunos de los pacientes habían sufrido reducción de la CVF. Respecto a la seguridad de los fármacos, los resultados muestran que ambos fármacos presentaron eventos o efectos adversos (EA), siendo la mayoría de ellos gastrointestinales, en caso de la pirfenidona 37,5% de pacientes y 66

Background: Nintedanib has anti-fibrotic and anti-inflammatory activity and is approved for the treatment of idiopathic pulmonary fibrosis. The aim of this study was to noninvasively assess the efficacy of nintedanib in a mouse model of partial lung irradiation to prevent radiation-induced lung damage (RILD).Methods: 266 C57BL/6 adult male mice were irradiated with a single radiation dose (0, 4, 8, 12, 16 or 20 Gy) using parallel-opposed fields targeting the upper right lung using a precision image-guided small animal irradiator sparing heart and spine based on micro-CT images. One week post irradiation, mice were randomized across nintedanib daily oral gavage treatment (0, 30 or 60 mg/kg). CT density analysis of the lungs was performed on monthly acquired micro-CT images. After 39 weeks, lungs were processed to evaluate the fibrotic phenotype.Results: Although the CT density increase correlated with the radiation dose, nintedanib did not influence this relationship. Immunohistochemical analysis confirmed the ability of nintedanib to reduce the microscopic fibrotic phenotype, in particular interstitial edema, interstitial and perivascular fibrosis and inflammation, and vasculitis.Conclusions: Nintedanib reduces radiation-induced lung fibrosis after partial lung irradiation without adverse effects, however, noninvasive CT imaging measuring electron density cannot be applied for monitoring its effects.

Background: Nintedanib, a tyrosine kinase inhibitor that is specific for platelet-derived growth factor receptors (PDGFR), fibroblast growth factor receptors (FGFR), and vascular endothelial growth factor receptors (VEGFR), has recently been approved for idiopathic pulmonary fibrosis. Fibrocytes are bone marrow-derived progenitor cells that produce growth factors and contribute to fibrogenesis in the lungs. However, the effects of nintedanib on the functions of fibrocytes remain unclear. Methods: Human monocytes were isolated from the peripheral blood of healthy volunteers. The expression of growth factors and their receptors in fibrocytes was analyzed using ELISA and Western blotting. The effects of nintedanib on the ability of fibrocytes to stimulate lung fibroblasts were examined in terms of their proliferation. The direct effects of nintedanib on the differentiation and migration of fibrocytes were also assessed. We investigated whether nintedanib affected the accumulation of fibrocytes in mouse lungs treated with bleomycin. Results: Human fibrocytes produced PDGF, FGF2, and VEGF-A. Nintedanib and specific inhibitors for each growth factor receptor significantly inhibited the proliferation of lung fibroblasts stimulated by the supernatant of fibrocytes. Nintedanib inhibited the migration and differentiation of fibrocytes induced by growth factors in vitro. The number of fibrocytes in the bleomycin-induced lung fibrosis model was reduced by the administration of nintedanib, and this was associated with anti-fibrotic effects. Conclusions: These results support the role of fibrocytes as producers of and responders to growth factors, and suggest that the anti-fibrotic effects of nintedanib are at least partly mediated by suppression of fibrocyte function.

Objectives Molecular profiling of advanced non-small-cell lung cancer (NSCLC) is recommended according to European and Italian guidelines. However, molecular routine assessment remains still heterogeneous. This observational study aimed to take a picture of the real clinical practice in molecular testing and therapeutic choices in advanced Italian NSCLCs. Materials and methods This study prospectively enrolled newly diagnosed advanced or recurrent NSCLCs referred to 38 Italian centres, from November 2014 to November 2015. Information regarding molecular profiling and treatment choices were collected. Description of patients’ outcome included overall survival (OS), progression-free survival in first (PFS1) and second-line (PFS2). Results and conclusion Among 1787 patients enrolled, 1388 (78%) performed at least one molecular analysis during the history of disease: 76% were tested for EGFR, 53% for ALK, 27% for KRAS, 16% for ROS1, 14% for BRAF, 5% for HER2, 4% for MET and 1% for FGFR. The remaining 399 patients (22.3%) did not receive any molecular test. Among patients receiving at least one molecular analysis, 583 (42%) presented a molecular alteration. Considering EGFR mutated and/or ALK rearranged patients (402), for which target agents were routinely reimbursed at time of study in Italy, the 86% received a personalized treatment as first and/or second line: the 90% (286) of EGFR mutants received an EGFR tyrosine kinase inhibitor, mostly gefitinib (41.1%) or afatinib (36.4%) while 74% (62) of ALK translocated patients received an ALK inhibitor, mostly crizotinib (64%). Median OS was 9.34 months (95% CI 8.62–10.0), median PFS1 was 4.61 months (95%CI 4.31–4.84) and median PFS2 was 2.76 months (95%CI 2.57–3.19). In the Italian clinical practice, routine molecular assessment was largely applied in NSCLC patients, according to national guidelines, but a low level of ALK test was reached. Most of EGFR mutants an ALK rearranged patients received a personalized treatment a

Lung cancer is still considered a big killer among cancer diseases, due to high incidence and mortality rates. The newer frontiers of therapeutic development regard the discovery of oncogene driven tumours: however, the majority of NSCLC patients are wild type and they cannot be treated with targeted based agents. The recent positive results obtained with immunotherapy and with the combination of angiogenesis inhibitors and docetaxel, changed the therapeutic scenario of the second line therapy of non squamous NSCLC without actionable mutations. A major issue is currently the lack of predictive biomarkers that could help the oncologists in the choice of the best second-line treatment. Aim of this project was to define an optimal therapeutic pathway for patients with non-squamous NSCLC, through a working group of a large number of Italian lung cancer oncologists. Panellists have identified and discussed the more significant criteria in the second-line setting for a therapeutic decision between the combination of angiogenesis inhibitors plus chemotherapy or immunotherapy. Finally, they expressed their preference on each criterion, building a proposal of a decision-making tree for a second-line treatment of non-squamous NSCLC.

[EN] Idiopathic pulmonary fibrosis is defined as chronic fibrosing interstitial pneumonia limited to the lung, with poor prognosis. The incidence has been rising in recent years probably due to improved diagnostic methods and increased life expectancy. In 2013, the SEPAR guidelines for the diagnosis and treatment for idiopathic pulmonary fibrosis were published. Since then, clinical trials and meta-analyses have shown strong scientific evidence for the use of pirfenidone and nintedanib in the treatment of idiopathic pulmonary fibrosis. In 2015, the international consensus of 2011 was updated and new therapeutic recommendations were established, prompting us to update our recommendation for the medical treatment of idiopathic pulmonary fibrosis accordingly. Diagnostic aspects and non-pharmacological treatment will not be discussed as no relevant developments have emerged since the 2013 guidelines., [ES] La fibrosis pulmonar idiopática es una enfermedad intersticial fibrosante limitada al pulmón, con mal pronóstico. Su incidencia ha aumentado en los últimos años, probablemente por la optimización de los métodos diagnósticos y el aumento en la esperanza de vida. En 2013 se publicó la normativa SEPAR sobre el diagnóstico y tratamiento de la fibrosis pulmonar idiopática. Desde entonces, se han publicado los resultados de ensayos clínicos y metaanálisis que han supuesto, con base en la evidencia científica, la introducción de pirfenidona y nintedanib en el tratamiento de la enfermedad. En 2015 se ha actualizado el consenso internacional de 2011, en el que se describen los cambios en las recomendaciones terapéuticas. Debido a ello cabía actualizar el apartado de la normativa sobre el tratamiento farmacológico de la fibrosis pulmonar idiopática. No se tratarán aspectos diagnósticos ni el tratamiento no farmacológico, ya que no se han producido cambios relevantes desde la normativa de 2013.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a challenging and multifactorial disease that has been thought for some time to lack effective treatments. The approval of two drugs, nintedanib and pirfenidone, has heralded a new era in its management. Areas covered: Currently, there is a growing interest on therapeutic strategies. Many studies have been designed and performed, although few of them turned out to be successful. Nowadays, nintedanib and pirfenidone are considered disease modifying drugs, recommended treatments by current evidence-based guidelines. A combined approach with more than one drug could be an effective strategy in IPF. However, data on combination therapy of the two approved drugs are still scarce, and ongoing trials are evaluating pharmacodynamic interactions and safety. The approved disease modifying drugs are also being assessed in combination with new molecules, showing promising results in preclinical models. Expert opinion: A deeper understanding of pathogenesis and key molecular mechanisms driving disease inception and progression will be key to identify novel agents to be tested both pre-clinically and clinically, possibly in combination with approved treatments. Looking at the near future, it is likely that clinical trials will adopt a phenotype-specific and pathway-specific approach, thus leading towards a personalized approach to IPF management.

Recently, two clinical trials of novel agents in metastatic ovarian cancer were published: a phase 3 study of nintedanib and a phase 2 study of volasertib. There seemed to be discordance between the results and conclusions in the publication of both these trials. Despite not very optimistic results, the studies concluded optimistically in favor of the new agents under study. Using these examples, we point out the discrepancies and the risks of concluding optimistically based on statistical significance when the actual benefit is minimal. We also appeal against conducting large phase 3 trials that require significant resources without good phase 2 evidence for doing so.

Background: It has been suggested that circulating fibrocytes and endothelial cells actively participate in the intense remodelling of the pulmonary vasculature in patients with idiopathic pulmonary fibrosis (IPF). Indeed, fibrotic areas exist that have fewer blood vessels, whereas adjacent non-fibrotic tissue is highly vascularized. The number of circulating endothelial cells (CEC) and endothelial progenitor cells (EPC) might reflect the balance between vascular injury and repair. Thus, fibrocytes as well as endothelial cells could potentially be used as biomarkers of disease progression and treatment outcome. Methods: Peripheral blood samples were collected from 67 patients with a multidisciplinary diagnosis of IPF and from 45 age-matched and sex-matched healthy volunteers. Buffy coat was isolated according to standard procedures and at least 20 million cells were stained with different monoclonal antibodies for the detection of CEC, EPC and circulating fibrocytes. For the detection of CEC and EPC, cells were stained with anti-CD45, anti-CD34, anti-CD133, anti-CD14, anti-CD309 and with the viability probe Far-Red LIVE/DEAD. For the detection of circulating fibrocytes, cells were first stained with LIVE/DEAD and the following monoclonal antibodies: anti-CD3, anti-CD19, anti-CD45, anti-CD34 and anti-CD14, then cells were fixed, permeabilized and stained with fluorochrome-conjugated anti-collagen I monoclonal antibodies. Results: Patients with IPF displayed almost undetectable levels of circulating fibrocytes, low levels of CEC, and normal levels of EPC. Patients treated with nintedanib displayed higher levels of CEC, but lower levels of endothelial cells expressing CD309 (the type II receptor for vascular endothelial growth factor). Treatment with both nintedanib and pirfenidone reduced the percentage of CEC and circulating fibrocytes. Conclusions: Levels of CEC were reduced in patients with IPF as compared to healthy individuals. The anti-fibrotic treatments ninted

Despite survival gains achieved nearly two decades ago with combination platinum- and taxane-based intravenous chemotherapy, overall survival curves have remained relatively unchanged during the 21st century using newer cytotoxic agents. Although combined intravenous-intraperitoneal (IV-IP) chemotherapy is promising, tolerability remains a significant issue. An emphasis has been placed on exploring dose dense schedules and targeted agents. Vascular endothelial growth factor (VEGF) has emerged as an important therapeutic target in several solid tumors including ovarian carcinoma. The monoclonal antibody, bevacizumab, binds VEGF, thus preventing activation of the VEGF receptor (VEGFR) leading to inhibition of tumor angiogenesis. To date eight phase 3 randomized controlled trials incorporating anti-angiogenesis therapy in the treatment of newly diagnosed and recurrent ovarian carcinoma have met their primary endpoints. Four of these trials included bevacizumab and were reported from 2010 to 2012. During 2013, the other four studies were reported, each studying one of the following novel anti-angiogenesis agents: pazopanib, cediranib, trebananib, and nintedanib. Importantly, none of these drugs have been approved by the United States Food and Drug Administration (US FDA) for the treatment of ovarian cancer. The purpose of this review will be to highlight both VEGF-dependent and non-VEGF dependent angiogenic pathways in ovarian cancer and discuss the phase 3 experiences and regulatory implications of targeting the tumor microenviroment with anti-angiogenesis therapy.

Despite survival gains achieved nearly two decades ago with combination platinum- and taxane-based intravenous chemotherapy, overall survival curves have remained relatively unchanged during the 21st century using newer cytotoxic agents. Although combined intravenous-intraperitoneal (IV-IP) chemotherapy is promising, tolerability remains a significant issue.

Therapeutic options for idiopathic pulmonary fibrosis (IPF) have been significantly extended last decade due to clinical use of drugs with confirmed antifibrotic activity, nintedanib and pirfenidone. Results of completed randomized phase III clinical trials (RCT) showed the ability of these drugs to decrease IPF progression and all-cause mortality compared to placebo. No direct comparison of efficacy and safety of different pharmacothera-peutic regimens with nintedanib and pirfenidone in IPF patients was published. The pooled odds ratio for mortality was 0.70 (95% confidential interval (CI), 0.47 – 1.03) in three trials of nintedanib (INPULSIS-1, INPULSIS-2, and TOMORROW; 2015) and 0.70 (0.47 – 1.02) in three trials of pirfenidone (CAPACITY-1, CAPACITY-2, and ASCEND). RCTs evaluating clinical efficacy of nintedanib and pirfenidone were not designed to assessment of mortality as the primary end-point; the primary end-point in all the trials was the change in the forced vital capacity of the lungs. Published metaanalyses demonstrated similar effects of nintedanib and pirfenidone on all-cause mortality and mortality from respiratory causes and confirmed favourable effects of both the drugs on course and progression of IPF. © 2017 Medical Education.
