First Data on Efficacy and Safety of Nintedanib in Patients with Idiopathic Pulmonary Fibrosis and Forced Vital Capacity of ?50 % of Predicted Value.

ABSTRACT: In the Phase III INPULSIS(®) trials, 52 weeks' treatment with nintedanib reduced decline in forced vital capacity (FVC) versus placebo in patients with idiopathic pulmonary fibrosis (IPF). Patients who completed the INPULSIS(®) trials could receive nintedanib in an open-label extension trial (INPULSIS(®)-ON). Patients with FVC <50 % predicted were excluded from INPULSIS(®), but could participate in INPULSIS(®)-ON. In patients with baseline FVC ?50 % and >50 % predicted at the start of INPULSIS(®)-ON, the absolute mean change in FVC from baseline to week 48 of INPULSIS(®)-ON was -62.3 and -87.9 mL, respectively (n = 24 and n = 558, respectively). No new safety signals were identified in INPULSIS(®)-ON compared with INPULSIS(®). The decline in FVC in INPULSIS(®)-ON in both subgroups by baseline FVC % predicted was similar to that in INPULSIS(®), suggesting that nintedanib may have a similar effect on disease progression in patients with advanced disease as in less advanced disease.

Project description:Importance:Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic lung disease with poor prognosis. Approved therapies do not halt disease progression. Objective:To determine the effect of recombinant human pentraxin 2 vs placebo on change from baseline to week 28 in mean forced vital capacity (FVC) percentage of predicted value. Design, Setting, and Participants:Phase 2, randomized, double-blind, placebo-controlled trial conducted at 18 sites in 7 countries of eligible patients with IPF (N = 117; aged 40-80 years; FVC ≥50% and ≤90% predicted; ratio of forced expiratory volume in the first second/FVC >0.70; diffusing capacity for carbon monoxide [Dlco] ≥25% and ≤90% predicted; and distance of ≥150 m on the 6-minute walk test). Study period was August 2015-May 2017. Interventions:Patients were randomized to receive either recombinant human pentraxin 2 (10 mg/kg intravenous every 4 weeks, n = 77) or placebo (n = 39) for 24 weeks, and stratified by concurrent IPF treatment status. Main Outcomes and Measures:The primary end point was the least-squares mean change in FVC percentage of predicted value from baseline to week 28 (minimal clinically important difference, decline of 2%-6%). Secondary end points included mean change in lung volumes (total, normal, and interstitial lung abnormalities) on high-resolution computed tomography (HRCT) and 6-minute walk distance (minimal clinically important difference, 24-45 m). Results:Of 117 randomized patients, 116 received at least 1 dose of study drug (mean age, 68.6 years; 81.0% men; mean time since IPF diagnosis, 3.8 years), and 111 (95.7%) completed the study. The least-squares mean change in FVC percentage of predicted value from baseline to week 28 in patients treated with recombinant human pentraxin 2 was -2.5 vs -4.8 for those in the placebo group (difference, +2.3 [90% CI, 1.1 to 3.5]; P = .001). No significant treatment differences were observed in total lung volume (difference, 93.5 mL [90% CI, -27.7 to 214.7]), quantitative parenchymal features on HRCT (normal lung volume difference, -1.2% [90% CI, -4.4 to 1.9]; interstitial lung abnormalities difference, 1.1% [90% CI, -2.2 to 4.3]), or measurement of Dlco (difference, -0.4 [90% CI, -2.6 to 1.7]). The change in 6-minute walk distance was -0.5 m for patients treated with recombinant human pentraxin 2 vs -31.8 m for those in the placebo group (difference, +31.3 m [90% CI, 17.4 to 45.1]; P < .001). The most common adverse events in the recombinant human pentraxin 2 vs placebo group were cough (18% vs 5%), fatigue (17% vs 10%), and nasopharyngitis (16% vs 23%). Conclusions and Relevance:In this preliminary study, recombinant human pentraxin 2 vs placebo resulted in a slower decline in lung function over 28 weeks for patients with idiopathic pulmonary fibrosis. Further research should more fully assess efficacy and safety. Trial Registration:clinicaltrials.gov Identifier: NCT02550873.

Project description:Mortality is an impractical primary endpoint for clinical trials in patients with idiopathic pulmonary fibrosis who have mild-to-moderate physiological impairment because event rates are low. Change in forced vital capacity (FVC) is widely accepted as a surrogate for mortality and is the most common primary endpoint in clinical trials for this disorder. Use of hospital admission as a predictor for mortality, independent of FVC decline, has not been well defined. We aimed to ascertain the independent and combined association of hospital admission and at least a 10% decrease in FVC with all-cause mortality.We did a pooled cohort study of 517 patients with idiopathic pulmonary fibrosis from three IPFnet multicentre randomised controlled trials. We compared the incidence of non-elective hospital admission and a 10% or greater reduction in FVC across strata of baseline physiological impairment. We used Cox proportional-hazards models to assess the risk of all-cause mortality associated with these surrogate events, occurring up to a predefined landmark timepoint. The three studies are registered at ClinicalTrials.gov, numbers NCT00650091, NCT00517933, and NCT00957242.Seven patients died before the landmark timepoint. Of the 510 patients remaining, 38 (7%) were admitted to hospital up to the predefined timepoint and 58 (11%) had a categorical decrease in FVC of at least 10%. Most patients admitted to hospital did not have a 10% or greater decrease in FVC (30 vs eight). Both surrogate events were associated with subsequent time to death from any cause (hazard ratio [HR] for admission 4·05, 95% CI 1·36-12·11 vs HR for 10% or greater decline in FVC 4·68, 1·83-11·99). When causes of hospital admission were considered, only respiratory events were associated with mortality (5·97, 1·81-19·74).Hospital admission might be an appropriate component of a clinically meaningful composite endpoint that improves the feasibility of clinical trials in idiopathic pulmonary fibrosis. Further studies are needed to refine the most appropriate definition of hospital admission for future trials.US National Heart, Lung, and Blood Institute (NHLBI), and The Cowlin Family Fund at the Chicago Community Trust.
