The European MultiPartner IPF registry (EMPIRE): validating long-term prognostic factors in idiopathic pulmonary fibrosis
Background/Objectives: Idiopathic pulmonary fibrosis (IPF) registries are established to enhance understanding of its natural history. Methods: Serbia (RS) participated in the EMPIRE (European Multi-Partner IPF Registry) from June 2015 to October 2022, involving four centers. The registry included patients over 18 diagnosed with IPF based on the 2011 international criteria. We aimed to gather key clinical, functional, and survival data, along with treatment information for IPF patients in RS, using a centralized electronic case report for consistency. Results: 188 RS patients participated (median age at diagnosis 65, 63.8% male, 51% smoking history, 56% radiological usual interstitial pneumonia (UIP) pattern). At the diagnosis, median forced vital capacity (FVC) was 73.7% and diffusion capacity for carbon monoxide (DLCO) was 38%. At initiation of antifibrotic therapy, median FVC was 73.2% (71.5% for deceased, 75.8% for survivors (p = 0.455), and DLCO was 33.8% (19.9% for deceased, and 35.6% for survivors (p = 0.046)). The median long-term survival from diagnosis was 29.4 months (95% CI: 22.6-36.2 months), and 9.4 months (95% CI: 5.9-12.9 months) from the initiation of therapy, with no difference in the duration of antifibrotic treatment between survivors and deceased (p = 0.598). Conclusions: The RS EMPIRE cohort represents a younger, less comorbid population with fewer smokers and more probable UIP, factors linked to a favorable prognosis. Nevertheless, survival was poorer than expected, mainly due to advanced disease severity at the time of antifibrotic initiation, as indicated by lower DLCO. These findings highlight the importance of earlier diagnosis and treatment before significant physiological decline to improve outcomes.

BACKGROUND: There is no clear evidence whether pirfenidone has a benefit in patients with probable or possible UIP, i.e. when idiopathic pulmonary fibrosis (IPF) is diagnosed with a lower degree of diagnostic certainty. We report on outcomes of treatment with pirfenidone in IPF patients diagnosed with various degrees of certainty. METHODS AND FINDINGS: We followed patients in the multi-national European MultiPartner IPF Registry (EMPIRE) first seen between 2015 and 2018. Patients were assessed with HRCT, histopathology and received a multi-disciplinary team (MDT) IPF diagnosis. Endpoints of interest were overall survival (OS), progression-free survival (PFS) and lung function decline. RESULTS: A total of 1626 patients were analysed, treated with either pirfenidone (N = 808) or receiving no antifibrotic treatment (N = 818). When patients treated with pirfenidone were compared to patients not receiving antifibrotic treatment, OS (one-, two- and three-year probability of survival 0.871 vs 0.798; 0.728 vs 0.632; 0.579 vs 0.556, P = 0.002), and PFS (one-, two- and three-year probability of survival 0.597 vs 0.536; 0.309 vs 0.281; 0.158 vs 0.148, P = 0.043) was higher, and FVC decline smaller (-0.073 l/yr vs -0.169 l/yr, P = 0.017). The benefit of pirfenidone on OS and PFS was also seen in patients with probable or possible IPF. CONCLUSIONS: This EMPIRE analysis confirms the favourable outcomes observed for pirfenidone treatment in patients with definitive IPF and indicates benefits also for patients with probable or possible IPF.

Idiopathic pulmonary fibrosis (IPF) is a rare lung disease with poor prognosis. The diagnosis and treatment possibilities are dependent on the health systems of countries. Hence, comparison among countries is difficult due to data heterogeneity. Our aim was to analyse patients with IPF in Central and Eastern Europe using the uniform data from the European Multipartner IPF registry (EMPIRE), which at the time of analysis involved 10 countries. Newly diagnosed IPF patients (N = 2,492, between March 6, 2012 and May 12, 2020) from Czech Republic (N = 971, 39.0%), Turkey (N = 505, 20.3%), Poland (N = 285, 11.4%), Hungary (N = 216, 8.7%), Slovakia (N = 149, 6.0%), Israel (N = 120, 4.8%), Serbia (N = 95, 3.8%), Croatia (N = 87, 3.5%), Austria (N = 55, 2.2%), and Bulgaria (N = 9, 0.4%) were included, and Macedonia, while a member of the registry, was excluded from this analysis due to low number of cases (N = 5) at this timepoint. Baseline characteristics, smoking habit, comorbidities, lung function values, CO diffusion capacity, high-resolution CT (HRCT) pattern, and treatment data were analysed. Patients were significantly older in Austria than in the Czech Republic, Turkey, Hungary, Slovakia, Israel, and Serbia. Ever smokers were most common in Croatia (84.1%) and least frequent in Serbia (39.2%) and Slovakia (42.6%). The baseline forced vital capacity (FVC) was >80% in 44.6% of the patients, between 50 and 80% in 49.3%, and <50% in 6.1%. Most IPF patients with FVC >80% were registered in Poland (63%), while the least in Israel (25%). A typical usual interstitial pneumonia (UIP) pattern was present in 67.6% of all patients, ranging from 43.5% (Austria) to 77.2% (Poland). The majority of patients received antifibrotic therapy (64.5%); 37.4% used pirfenidone (range 7.4-39.8% between countries); and 34.9% nintedanib (range 12.6-56.0% between countries) treatment. In 6.8% of the cases, a therapy switch was initiated between the 2 antifibrotic agents. Significant differences in IPF patient characteristics and access to antifibrotic therapies exist in EMPIRE countries, which needs further investigation and strategies to improve and harmonize patient care and therapy availability in this region.

BACKGROUND: The antifibrotic drugs nintedanib and pirfenidone are used for the treatment of idiopathic pulmonary fibrosis (IPF). We analysed the association of common profibrotic polymorphisms in MUC5B (mucin 5B, rs35705950) and DSP (desmoplakin, rs2076295) on antifibrotic treatment outcomes in IPF. METHODS: MUC5B rs35705950 and DSP rs2076295 were assessed in IPF patients (n = 210, 139 men/71 women) from the Czech EMPIRE registry and age- or sex-matched healthy individuals (n = 205, 125 men/80 women). Genetic data were collated with overall survival (OS), acute exacerbation episodes, worsening lung function and antifibrotic treatment. RESULTS: We confirmed overexpression of the MUC5B rs35705950*T allele (55.2% versus 20.9%, p < 0.001) and the DSP rs2076295*G allele (80.4% versus 68.3%, p < 0.001) in IPF compared with controls. On antifibrotic drugs, lower mortability was observed in IPF patients with DSP G* allele (p = 0.016) and MUC5B T* allele (p = 0.079). Carriers of the DSP rs2076295*G allele benefitted from nintedanib treatment compared with TT genotype by a longer OS [hazard ratio (HR) = 7.99; 95% confidence interval (CI) = 1.56-40.90; p = 0.013] and a slower decline in lung function (HR = 8.51; 95% CI = 1.68-43.14; p = 0.010). Patients with a TT genotype (rs2076295) benefitted from treatment with pirfenidone by prolonged OS (p = 0.040; HR = 0.35; 95% CI = 0.13-0.95) compared with nintedanib treatment. Both associations were confirmed by cross-validation analysis. After stratifying by MUC5B rs35705950*T allele carriage, no difference in treatment outcome was observed for nintedanib or pirfenidone (p = 0.784). In the multivariate model, smoking, age, forced vital capacity (FVC) and DLCO (diffuse lung capacity) at the IPF diagnosis were associated with survival. CONCLUSION: Our real-world study showed that IPF patients with MUC5B T* allele or DSP G* allele profit from antifibrotic treatment by lower mortability. Moreover, carriers of the DSP rs2076295*G allele benefit from treatment with nintedanib, and TT genotype from treatment with pirfenidone. MUC5B rs35705950 did not impact the outcome of treatment with either nintedanib or pirfenidone. Our single-registry pilot study should be confirmed with an independent patient cohort.

INTRODUCTION: Nintedanib, a tyrosine kinase receptor inhibitor, may be associated with increased bleeding risk. Thus, patients with an inherited predisposition to bleeding, or those receiving therapeutic doses of anticoagulants or high-dose antiplatelet therapy, have been excluded from clinical trials of nintedanib in idiopathic pulmonary fibrosis (IPF). OBJECTIVE: Our objective was to examine real-world bleeding events in patients with IPF treated with antifibrotics, including those receiving anticoagulants and/or antiplatelet therapy. METHODS: The European MultiPartner IPF Registry (EMPIRE) enrolled 2794 patients with IPF: group A (1828: no anticoagulant or antiplatelet treatment), group B (227: anticoagulant treatment), group C (659: antiplatelet treatment), and group D (80: anticoagulant and antiplatelet treatment). Overall, 673 (24.1%) received nintedanib and 933 (33.4%) received pirfenidone. Bleeding events and their relationship to antifibrotic and anticoagulation treatment were characterized. RESULTS: Group A patients, versus those in groups B, C, and D, were typically younger and generally had the lowest comorbidity rates. A higher proportion of patients in groups A and C, versus group B, received nintedanib. Pirfenidone, most common in group D, was more evenly balanced across groups. In patients with reported bleeding events, seven of eight received nintedanib (groups A, C, and D). Bleeding incidence was 3.0, 0, 1.3, and 18.1 per 10,000 patient-years (groups A, B, C, and D, respectively). CONCLUSION: Real-world data from EMPIRE showed that patients on anticoagulant medications received nintedanib less frequently, perhaps based on its mechanism of action. Overall, bleeding incidence was low (0.29%: nintedanib 0.25%; pirfenidone 0.04%) and irrespective of anticoagulant or antiplatelet therapy received (P = 0.072).
