RESUMO
RATIONALE: There is no consensus as to when treatment for idiopathic pulmonary fibrosis (IPF) should be initiated. Some physicians prefer not to treat patients with preserved lung volume. OBJECTIVE: To investigate whether patients with IPF and preserved lung volume receive the same benefit from nintedanib as patients with more impaired lung volume. METHODS: Post hoc subgroup analyses of pooled data from the two replicate phase III INPULSIS trials by baseline FVC % predicted (≤90%, >90%). RESULTS: At baseline, 274 patients had FVC >90% predicted and 787 patients had FVC ≤90% predicted. In patients treated with placebo, the adjusted annual rate of decline in FVC was consistent between patients with FVC >90% predicted and FVC ≤90% predicted (-224.6â mL/year and -223.6â mL/year, respectively). There was no statistically significant difference between these subgroups in the effect of nintedanib on annual rate of decline in FVC, change from baseline in St George's Respiratory Questionnaire total score or time to first acute exacerbation. In patients with baseline FVC >90% predicted and ≤90% predicted, respectively, the adjusted annual rate of decline in FVC with nintedanib was -91.5â mL/year (difference vs placebo: 133.1â mL/year (95% CI 68.0 to 198.2)) and -121.5â mL/year (difference vs placebo: 102.1â mL/year (95% CI 61.9 to 142.3)). Adverse events associated with nintedanib were similar in both subgroups. CONCLUSIONS: Patients with IPF and preserved lung volume (FVC >90% predicted) have the same rate of FVC decline and receive the same benefit from nintedanib as patients with more impaired lung volume. TRIAL REGISTRATION NUMBER: NCT01335464 and NCT01335477.

Time to first investigator-reported acute exacerbation was a key secondary end-point in the INPULSIS trials of nintedanib in patients with idiopathic pulmonary fibrosis (IPF).We used the INPULSIS trial data to investigate risk factors for acute exacerbation of IPF and to explore the impact of nintedanib on risk and outcome of investigator-reported and adjudicated confirmed/suspected acute exacerbations. Mortality following these events and events adjudicated as not acute exacerbations was analysed using the log rank test.Risk of acute exacerbations was most strongly associated with the following variables: baseline forced vital capacity (higher risk with lower value), baseline supplemental oxygen (higher risk with use), baseline antacid medication (higher risk with use), treatment (higher risk with placebo), and for confirmed/suspected acute exacerbations, cigarette smoking. Mortality was similar following investigator-reported and adjudicated confirmed/suspected acute exacerbations. Nintedanib had no significant effect on risk of mortality post-exacerbation.Investigator-reported acute exacerbations of IPF are associated with similar risk factors and outcomes as adjudicated confirmed/suspected acute exacerbations.

BACKGROUND: Combinations of long-acting bronchodilators are recommended to reduce the rate of chronic obstructive pulmonary disease (COPD) exacerbations. It is unclear whether combining olodaterol, a long-acting beta-agonist, with tiotropium, a long-acting anti-muscarinic, reduces the rate of exacerbations compared with tiotropium alone. METHODS: This 52-week, double-blind, randomised, parallel-group, active-controlled trial randomly assigned (1:1) patients with COPD with a history of exacerbations using a randomised block design to receive tiotropium-olodaterol 5 µg-5 µg or tiotropium 5 µg once daily. Patients using inhaled corticosteroids continued this therapy. Treatment was masked to patients, investigators, and those involved in analysing the data. The primary endpoint was the rate of moderate and severe COPD exacerbations from the first dose of medication until 1 day after last drug administration. The primary analysis included all randomly assigned patients who received any dose of study medication but were not from a site excluded due to on-site protocol violations. The trial is registered with ClinicalTrials.gov, number NCT02296138. FINDINGS: Overall, 9009 patients were screened from 818 centres in 51 countries. We recruited 7880 patients between Jan 22, 2015 and March 7, 2016 (mean age 66·4 years [SD 8·5], 5626 [71%] were men, mean FEV1 percent predicted 44·5% [SD 27·7]): 3939 received tiotropium-olodaterol and 3941 tiotropium. The rate of moderate and severe exacerbations was lower with tiotropium-olodaterol than tiotropium (rate ratio [RR] 0·93, 99% CI 0·85-1·02; p=0·0498), not meeting the targeted 0·01 significance level. The proportion of patients reporting adverse events was similar between treatments. INTERPRETATION: Combining tiotropium and olodaterol did not reduce exacerbation rate as much as expected compared with tiotropium alone. FUNDING: Boehringer Ingelheim International GmbH.

INTRODUCTION: Tiotropium is prescribed for the treatment of chronic obstructive pulmonary disease (COPD) and delivered via HandiHaler(®) (18 µg once daily) or Respimat(®) Soft Mist™ inhaler (5 µg once daily). The recent TIOtropium Safety and Performance In Respimat(®) (TIOSPIR™) study demonstrated that both exhibit similar safety profiles. This analysis provides an updated comprehensive safety evaluation of tiotropium(®) using data from placebo-controlled HandiHaler(®) and Respimat(®) trials. METHODS: Pooled analysis of adverse event (AE) data from tiotropium HandiHaler(®) 18 µg and Respimat(®) 5 µg randomized, double-blind, parallel-group, placebo-controlled, clinical trials in patients with COPD (treatment duration ≥4 weeks). Incidence rates, rate ratios (RRs), and 95% confidence intervals (CIs) were determined for HandiHaler(®) and Respimat(®) trials, both together and separately. RESULTS: In the 28 HandiHaler(®) and 7 Respimat(®) trials included in this analysis, 11,626 patients were treated with placebo and 12,929 with tiotropium, totaling 14,909 (12,469 with HandiHaler(®); 2,440 with Respimat(®)) patient-years of tiotropium exposure. Mean age was 65 years, and mean prebronchodilator forced expiratory volume in 1 second (FEV1) was 1.16 L (41% predicted). The risk (RR [95% CI]) of AEs (0.90 [0.87, 0.93]) and of serious AEs (SAEs) (0.94 [0.89, 0.99]) was significantly lower in the tiotropium than in the placebo group (HandiHaler(®) and Respimat(®) pooled results), and there was a numerically lower risk of fatal AEs (FAEs) (0.90 [0.79, 1.01]). The risk of cardiac AEs (0.93 [0.85, 1.02]) was numerically lower in the tiotropium group. Incidences of typical anticholinergic AEs, but not SAEs, were higher with tiotropium. Analyzed separately by inhaler, the risks of AE and SAE in the tiotropium groups remained lower than in placebo and similarly for FAEs. CONCLUSION: This analysis indicates that tiotropium is associated with lower rates of AEs, SAEs, and similar rates of FAEs than placebo when delivered via HandiHaler(®) or Respimat(®) (overall and separately) in patients with COPD.

BACKGROUND: Tiotropium + olodaterol improves lung function and symptoms compared to monotherapies in chronic obstructive pulmonary disease (COPD). The OTEMTO 1 and 2 studies investigated the effects of tiotropium + olodaterol on lung function and health-related quality of life compared to placebo in patients with moderate to severe COPD. METHODS: In these two replicate, double-blind, parallel-group, placebo-controlled trials, patients were randomised to receive tiotropium + olodaterol 5/5 µg, 2.5/5 µg, tiotropium 5 µg or placebo for 12 weeks, via the Respimat(®) inhaler. Primary end points were St George's Respiratory Questionnaire (SGRQ) total score, forced expiratory volume in 1 s (FEV1) area under the curve from 0 to 3 h (AUC0-3) response and trough FEV1 response. RESULTS: In OTEMTO 1 and 2, tiotropium + olodaterol 5/5 µg improved SGRQ total score by 4.89 (95% confidence interval [CI] -6.90, -2.88) and 4.56 (95% CI -6.50, -2.63) units versus placebo (both p < 0.0001), and 2.49 (95% CI -4.47, -0.51; p < 0.05) and 1.72 (95% CI -3.63, 0.19) units versus tiotropium 5 µg. Tiotropium + olodaterol 2.5/5 µg significantly improved SGRQ score compared to placebo. Both doses significantly improved FEV1 AUC0-3 response compared to placebo and tiotropium 5 µg. Tiotropium + olodaterol 5/5 and 2.5/5 µg also significantly improved trough FEV1 response compared to placebo (both studies) and separated from tiotropium 5 µg in OTEMTO 2. Adverse-event incidence was similar between treatment groups. CONCLUSION: Tiotropium + olodaterol improved lung function and quality of life compared to placebo and tiotropium 5 µg.
