Exploring characteristics of COPD patients with clinical improvement after integrated disease management or usual care: post-hoc analysis of the RECODE study.

ABSTRACT: BACKGROUND:The cluster randomized controlled trial on (cost-)effectiveness of integrated chronic obstructive pulmonary disease (COPD) management in primary care (RECODE) showed that integrated disease management (IDM) in primary care had no effect on quality of life (QOL) in COPD patients compared with usual care (guideline-supported non-programmatic care). It is possible that only a subset of COPD patients in primary care benefit from IDM. We therefore examined which patients benefit from IDM, and whether patient characteristics predict clinical improvement over time. METHOD:Post-hoc analyses of the RECODE trial among 1086 COPD patients. Logistic regression analyses were performed with baseline characteristics as predictors to examine determinants of improvement in QOL, defined as a minimal decline in Clinical COPD Questionnaire (CCQ) of 0.4 points after 12 and 24?months of IDM. We also performed moderation analyses to examine whether predictors of clinical improvement differed between IDM and usual care. RESULTS:Regardless of treatment type, more severe dyspnea (MRC) was the most important predictor of clinically improved QOL at 12 and 24?months, suggesting that these patients have most room for improvement. Clinical improvement with IDM was associated with female gender (12-months) and being younger (24-months), and improvement with usual care was associated with having a depression (24-months). CONCLUSIONS:More severe dyspnea is a key predictor of improved QOL in COPD patients over time. More research is needed to replicate patient characteristics associated with clinical improvement with IDM, such that IDM programs can be offered to patients that benefit the most, and can potentially be adjusted to meet the needs of other patient groups as well.

Project description:BACKGROUND:Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with loss of lung function and poor outcomes for patients. However, there are limited data on the time course of changes in forced expiratory volume in 1?s (FEV1) preceding the first reported symptom and after the start of an exacerbation. METHODS:WISDOM was a multinational, randomized, double-blind, active-controlled, 52-week study in patients with severe-to-very severe COPD. Patients received triple therapy (long-acting muscarinic antagonist and long-acting ?2-agonist/inhaled corticosteroid [ICS]) for 6?weeks, and were randomized to continue triple therapy or stepwise withdrawal of the ICS (dual bronchodilator group). After suitable training, patients performed daily spirometry at home using a portable, battery-operated spirometer. In the present post hoc analysis, patients who continued to perform daily home spirometry and completed at least one measurement per week for a 56-day period before and after the start of a moderate or severe exacerbation were included. Missing values were imputed by linear interpolation (intermittent), backfilling (beginning) or carry forward (end). Exacerbation onset was the first day of a reported symptom of exacerbation. RESULTS:Eight hundred and eighty-eight patients in the WISDOM study had a moderate/severe exacerbation after the complete ICS withdrawal visit; 360 of them contributed at least one FEV1 measure per week for the 8?weeks before and after the event and are included in this analysis. Mean daily FEV1 began to decline from approximately 2?weeks before the onset of symptoms of an exacerbation, dropping from 0.907?L (mean Days -?56 to -?36 before the exacerbation) to 0.860?L on the first day of the exacerbation. After the exacerbation, mean FEV1 improved but did not return to pre-exacerbation levels (mean Days 36-56 after the exacerbation, 0.875?L). The pattern of FEV1 changes around exacerbations was similar in the triple therapy and dual bronchodilator groups, and a similar pattern was seen in moderate and severe exacerbations when analysed separately. CONCLUSIONS:Mean lung function starts to decline prior to the first reported symptoms of an exacerbation, and does not recover to pre-exacerbation levels 8?weeks after the event.

Project description:BackgroundIn chronic obstructive pulmonary disease (COPD), both the time needed for patients to gain symptom improvement with long-acting bronchodilator therapy and whether an early response is predictive of a sustained response is unknown. This study aimed to investigate how quickly meaningful symptom responses are seen in patients with COPD with bronchodilator therapy and whether these responses are sustained.MethodsEarly MAXimisation of bronchodilation for improving COPD stability (EMAX) was a 24-week, double-blind, double-dummy, parallel-group trial that randomised patients to umeclidinium/vilanterol (UMEC/VI), umeclidinium or salmeterol. Daily Evaluating Respiratory Symptoms in COPD (E-RS:COPD) score and rescue salbutamol use were captured via an electronic diary and analysed initially in 4-weekly periods. Post hoc analyses assessed change from baseline in daily E-RS:COPD score and rescue medication use weekly (Weeks 1-8), and association between E-RS:COPD responder status at Weeks 1-4 and later time points.ResultsIn the intent-to-treat population (n = 2425), reductions from baseline in E-RS:COPD scores and rescue medication use were apparent from Day 2 with all treatments. Treatment differences for UMEC/VI versus either monotherapy plateaued by Week 4-8 and were sustained at Weeks 21-24; improvements were consistently greater with UMEC/VI. For all treatments, most patients (60-85%) retained their Weeks 1-4 E-RS:COPD responder/non-responder status at Weeks 21-24. Among patients receiving UMEC/VI who were E-RS:COPD responders at Weeks 1-4, 70% were responders at Weeks 21-24.ConclusionPatients with symptomatic COPD had greater potential for early symptom improvements with UMEC/VI versus either monotherapy. This benefit was generally maintained for 24 weeks. Early monitoring of treatment response can provide clinicians with an early indication of a patient's likely longer-term response to prescribed bronchodilator treatment and will facilitate appropriate early adjustments in care.Clinical trial registrationNCT03034915, 2016-002513-22 (EudraCT Number).

Project description:IntroductionAssessing clinically important measures of disease progression is essential for evaluating therapeutic effects on disease stability in chronic obstructive pulmonary disease (COPD). This analysis assessed whether providing additional bronchodilation with the long-acting muscarinic antagonist umeclidinium (UMEC) to patients treated with inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) therapy would improve disease stability compared with ICS/LABA therapy alone.MethodsThis integrated post hoc analysis of four 12-week, randomized, double-blind trials (NCT01772134, NCT01772147, NCT01957163, NCT02119286) compared UMEC 62.5 µg with placebo added to open-label ICS/LABA in symptomatic patients with COPD (modified Medical Research Council dyspnea scale score ≥ 2). A clinically important deterioration (CID) was defined as: a decrease from baseline of ≥ 100 mL in trough forced expiratory volume in 1 s (FEV1), an increase from baseline of ≥ 4 units in St George's Respiratory Questionnaire (SGRQ) total score, or a moderate/severe exacerbation. Risk of a first CID was evaluated in the intent-to-treat (ITT) population and in patients stratified by Global initiative for chronic Obstructive Lung Disease (GOLD) classification, exacerbation history and type of ICS/LABA therapy. Adverse events (AEs) were also assessed.ResultsOverall, 1637 patients included in the ITT population received UMEC + ICS/LABA (n = 819) or placebo + ICS/LABA (n = 818). Additional bronchodilation with UMEC reduced the risk of a first CID by 45-58% in the ITT population and all subgroups analyzed compared with placebo (all p < 0.001). Improvements were observed in reducing FEV1 (69% risk reduction; p < 0.001) and exacerbation (47% risk reduction; p = 0.004) events in the ITT population. No significant reduction in risk of a SGRQ CID was observed. AE incidence was similar between treatment groups.ConclusionSymptomatic patients with COPD receiving ICS/LABA experience frequent deteriorations. Additional bronchodilation with UMEC significantly reduced the risk of CID and provided greater short-term stability versus continued ICS/LABA therapy in these patients.FundingGlaxoSmithKline (study number: 202067).

Project description:A previous Phase IIIb study (NCT01462929) in patients with moderate to severe COPD demonstrated that 6 weeks of treatment with aclidinium led to improvements in 24-hour bronchodilation comparable to those with tiotropium, and improvement of symptoms versus placebo. This post hoc analysis was performed to assess the effect of treatment in the symptomatic patient group participating in the study.Symptomatic patients (defined as those with Evaluating Respiratory Symptoms [E-RS™] in COPD baseline score ?10 units) received aclidinium bromide 400 ?g twice daily (BID), tiotropium 18 ?g once daily (QD), or placebo, for 6 weeks. Lung function, COPD respiratory symptoms, and incidence of adverse events (AEs) were assessed.In all, 277 symptomatic patients were included in this post hoc analysis. Aclidinium and tiotropium treatment improved forced expiratory volume in 1 second (FEV1) from baseline to week 6 at all time points over 24 hours versus placebo. In addition, improvements in FEV1 from baseline during the nighttime period were observed for aclidinium versus tiotropium on day 1 (aclidinium 157 mL, tiotropium 67 mL; P<0.001) and week 6 (aclidinium 153 mL, tiotropium 90 mL; P<0.05). Aclidinium improved trough FEV1 from baseline versus placebo and tiotropium at day 1 (aclidinium 136 mL, tiotropium 68 mL; P<0.05) and week 6 (aclidinium 137 mL, tiotropium 71 mL; P<0.05). Aclidinium also improved early-morning and nighttime symptom severity, limitation of early-morning activities, and E-RS Total and domain scores versus tiotropium (except E-RS Chest Symptoms) and placebo over 6 weeks. Tolerability showed similar incidence of AEs in each arm.In this post hoc analysis of symptomatic patients with moderate to severe COPD, aclidinium 400 ?g BID provided additional improvements compared with tiotropium 18 ?g QD in: 1) bronchodilation, particularly during the nighttime, 2) daily COPD symptoms (E-RS), 3) early-morning and nighttime symptoms, and 4) early-morning limitation of activity.

Project description:Purpose: Moderate and severe COPD exacerbations are a significant health-care burden, but patients also experience "mild" exacerbations, or COPD symptom-related attacks, which often go unreported. We aimed to define and then determine the incidence of COPD symptom-related attacks and their impact on future risk of moderate/severe exacerbations, health-related quality of life (HRQoL), and lung function. The effect of COPD maintenance therapy on the attack definition was then evaluated by comparing budesonide/formoterol with formoterol alone.Patients and methods: This post hoc analysis of the RISE study defined COPD symptom-related attacks as ?2 consecutive days of both worsening symptoms and increased daily rescue medication use based upon thresholds of >2 and >4 short-acting ?2-agonist (SABA) inhalations/day above baseline. The impact of these events on subsequent moderate/severe exacerbation risk was estimated using a time-varying Cox proportional hazards model. The effects of COPD symptom-related attacks on St George's Respiratory Questionnaire (SGRQ) total score and pre-bronchodilator forced expiratory volume in 1 second (FEV1) were evaluated as average changes from baseline to first post-attack measurement. Rates of attacks were compared between treatment groups using negative binomial regression models.Results: COPD symptom-related attacks elevated the risk of subsequent moderate/severe exacerbations at both >2 and >4 inhalations/day above baseline (HR 1.86 and 2.21, respectively; p<0.0001), with a cumulative increase in risk with increasing attacks. HRQoL and lung function were reduced for patients with ?1 versus no COPD symptom-related attacks at both rescue medication thresholds. There were fewer COPD symptom-related attacks with budesonide/formoterol versus formoterol alone, with no increased risk of pneumonia and lower respiratory tract infections.Conclusion: COPD symptom-related attacks are common and typically unreported. Importantly, these attacks can account for considerable morbidity and should not be regarded as "mild". Detection of such exacerbations may be valuable in identifying patients at greater risk and guiding preventive therapeutic interventions.

Project description:IntroductionLong-acting muscarinic antagonists (LAMAs), long-acting β2-agonists (LABAs), inhaled corticosteroids (ICS), and their combinations, are recommended for the treatment of chronic obstructive pulmonary disease (COPD). This study aimed to determine whether the safety and efficacy of aclidinium bromide differs by baseline maintenance LABA and ICS therapies.MethodsASCENT-COPD was a phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study of patients with moderate-to-very severe COPD and increased cardiovascular risk. Patients were randomized 1:1 to receive aclidinium 400 μg or placebo twice daily, via a multidose dry-powder inhaler for up to 3 years. Outcomes included time to first major adverse cardiovascular events (MACE), all-cause mortality, change from baseline in trough forced expiratory volume in 1 s (FEV1), and COPD assessment test (CAT) total score over 3 years, and annual moderate-to-severe COPD exacerbation rate in patients receiving aclidinium or placebo with maintenance LABA monotherapy, ICS monotherapy, LABA + ICS (fixed/free), or no maintenance therapy (neither LABA nor ICS) at baseline.ResultsA total of 3589 patients were included (LABA, n = 227; ICS, n = 290; LABA + ICS, n = 2058; no maintenance, n = 1130). Aclidinium did not increase the risk of MACE or all-cause mortality versus placebo, regardless of baseline maintenance treatment. Reductions in moderate-to-severe exacerbation rates were observed with aclidinium versus placebo in all subgroups [LABA 43% (P = 0.046); ICS 25% (P = 0.202); LABA + ICS 22% (P = 0.003); no maintenance 18% (P = 0.130)]. Aclidinium improved morning trough FEV1 irrespective of baseline therapy and CAT total scores, except for LABA and ICS subgroups, versus placebo at several time points.ConclusionIn patients with moderate-to-severe COPD and CV risk factors, the addition of aclidinium to maintenance therapy with LABA or LABA + ICS provided further benefit.Trial registrationClinicalTrials.gov identifier NCT01966107.
