A randomised, placebo-controlled trial of anti-interleukin-1 receptor 1 monoclonal antibody MEDI8968 in chronic obstructive pulmonary disease.

ABSTRACT: BACKGROUND:Interleukin-1 receptor 1 (IL-1R1) inhibition is a potential strategy for treating patients with chronic obstructive pulmonary disease (COPD). MEDI8968, a fully human monoclonal antibody, binds selectively to IL-1R1, inhibiting activation by IL-1? and IL-1?. We studied the efficacy and safety/tolerability of MEDI8968 in adults with symptomatic, moderate-to-very severe COPD. METHODS:This was a phase II, randomised, double-blind, placebo-controlled, multicentre, parallel-group study. Subjects aged 45-75 years and receiving standard maintenance therapy with ?2 exacerbations in the past year were randomised 1:1 to receive placebo or MEDI8968 300 mg (600 mg intravenous loading dose) subcutaneously every 4 weeks, for 52 weeks. The primary endpoint was the moderate/severe acute exacerbations of COPD (AECOPD) rate (week 56 post-randomisation). Secondary endpoints were severe AECOPD rate and St George's Respiratory Questionnaire-COPD (SGRQ-C) score (week 56 post-randomisation). RESULTS:Of subjects randomised to placebo (n = 164) and MEDI8968 (n = 160), 79.3% and 75.0%, respectively, completed the study. There were neither statistically significant differences between treatment groups in moderate/severe AECOPD rate ([90% confidence interval]: 0.78 [0.63, 0.96], placebo; 0.71 [0.57, 0.90], MEDI8968), nor in severe AECOPD rate or SGRQ-C scores. Post-hoc analysis of subject subgroups (by baseline neutrophil count or tertiles of circulating neutrophil counts) did not alter the study outcome. The incidence of treatment-emergent adverse events (TEAEs) with placebo and MEDI8968 treatment was similar. The most common TEAE was worsening of COPD. CONCLUSIONS:In this phase II study, MEDI8968 did not produce statistically significant improvements in AECOPD rate, lung function or quality of life.

Project description:BACKGROUND:Chronic obstructive pulmonary disease (COPD) is associated with eosinophilic airway inflammation in 10-20% of patients. Benralizumab, an anti-interleukin-5 receptor ? monoclonal antibody, depletes blood and sputum eosinophils. We aimed to establish whether benralizumab reduces acute exacerbations of COPD in patients with eosinophilia and COPD. METHODS:We did this randomised, double-blind, placebo-controlled, phase 2a study between Nov 18, 2010, and July 13, 2013, at 26 sites in the UK, Poland, Germany, Canada, the USA, Denmark, and Spain. Adults aged 40-85 years, with moderate-to-severe COPD, at least one acute exacerbation of COPD, and a sputum eosinophil count of 3·0% or more within the previous year, were randomly assigned (1:1) via computer-generated permuted block randomisation (block size of four), with an interactive voice or web-response system, to receive placebo or 100 mg benralizumab subcutaneously, every 4 weeks (three doses), then every 8 weeks (five doses) over 48 weeks. Study site personnel included in study assessments, participants, and data analysts, were masked to treatment allocation. The primary endpoint was the annualised rate of acute exacerbations of COPD at week 56, defined as the number of acute exacerbations divided by total duration of person-year follow-up. Secondary and exploratory endpoints included COPD-specific Saint George's Respiratory Questionnaire (SGRQ-C), Chronic Respiratory Questionnaire self-administered standardised format (CRQ-SAS), pre-bronchodilator forced expiratory volume in 1 second (FEV1), and safety. We did a prespecified subgroup analysis by baseline blood eosinophil count. Analyses were by intention to treat and per-protocol. This trial is registered with ClinicalTrials.gov, number NCT01227278. FINDINGS:We randomly assigned 101 patients to receive placebo (n=50) or benralizumab (n=51), of whom 88 (87%) patients completed the study. Six patients who completed the study were excluded from the per-protocol population because of major protocol violations; the per-protocol population thus included 82 patients. Benralizumab did not reduce the annualised rate of acute exacerbations of COPD compared with placebo in the per-protocol population, with rates of 0·95 (0·68-1·29; n=40) versus 0·92 (0·67-1·25; n=42). Mean pre-bronchodilator FEV1 change from baseline to week 56 was -0·06 L (SD 0·24) with placebo, and 0·13 L (0·41) with benralizumab (p=0·014). Numerical, albeit non-significant, improvement in acute exacerbations of COPD, SGRQ-C, CRQ-SAS, and FEV1 were greater in benralizumab-treated patients with baseline blood eosinophil concentrations of 200 cells per ?L or more or 300 cells per ?L or more. Incidence of treatment-emergent adverse events was similar between the two groups, with the most common events being respiratory disorders (31 [62%] of 50 patients given placebo vs 32 [63%] of 51 given benralizumab) and infections (28 [56%] vs 27 [53%]). A higher incidence of serious treatment-emergent adverse events were recorded in patients in the benralizumab group than in those in the placebo group (14 vs nine patients), although none of these events were considered by the investigator to be benralizumab related. INTERPRETATION:Compared with placebo, benralizumab did not reduce the rate of acute exacerbations of COPD. However, the results of prespecified subgroup analysis support further investigation of benralizumab in patients with COPD and eosinophilia. FUNDING:MedImmune.

Project description:BACKGROUND:Increased iron availability modifies cardiorespiratory function in healthy volunteers and improves exercise capacity and quality of life in patients with heart failure or pulmonary hypertension. We hypothesised that intravenous iron would produce improvements in oxygenation, exercise capacity and quality of life in patients with chronic obstructive pulmonary disease (COPD). METHODS:We performed a randomised, placebo-controlled, double-blind trial in 48 participants with COPD (mean±SD: age 69±8 years, haemoglobin 144.8±13.2?g/L, ferritin 97.1±70.0?µg/L, transferrin saturation 31.3%±15.2%; GOLD grades II-IV), each of whom received a single dose of intravenous ferric carboxymaltose (FCM; 15?mg/kg bodyweight) or saline placebo. The primary endpoint was peripheral oxygen saturation (SpO2) at rest after 1?week. The secondary endpoints included daily SpO2, overnight SpO2, exercise SpO2, 6?min walk distance, symptom and quality of life scores, serum iron indices, spirometry, echocardiographic measures, and exacerbation frequency. RESULTS:SpO2 was unchanged 1?week after FCM administration (difference between groups 0.8%, 95%?CI -0.2% to 1.7%). However, in secondary analyses, exercise capacity increased significantly after FCM administration, compared with placebo, with a mean difference in 6?min walk distance of 12.6?m (95%?CI 1.6 to 23.5?m). Improvements of ?40?m were observed in 29.2% of iron-treated and 0% of placebo-treated participants after 1?week (p=0.009). Modified MRC Dyspnoea Scale score was also significantly lower after FCM, and fewer participants reported scores ?2 in the FCM group, compared with placebo (33.3% vs 66.7%, p=0.02). No significant differences were observed in other secondary endpoints. Adverse event rates were similar between groups, except for hypophosphataemia, which occurred more frequently after FCM (91.7% vs 8.3%, p<0.001). CONCLUSIONS:FCM did not improve oxygenation over 8 weeks in patients with COPD. However, this treatment was well tolerated and produced improvements in exercise capacity and functional limitation caused by breathlessness. These effects on secondary endpoints require confirmation in future studies. TRIAL REGISTRATION NUMBER:ISRCTN09143837.

Project description:The efficacy of inhaled salmeterol plus fluticasone propionate (SFC) in patients with severe or very severe COPD is well documented. However, there are only limited data about the influence of GOLD severity staging on the effectiveness of SFC, particularly in patients with milder disease.TORCH was a 3-year, double-blind, placebo-controlled trial of 6112 patients with moderate/severe COPD with pre-bronchodilator FEV1 < 60% predicted (mean age 65 years, 76% male, mean 44% predicted FEV1, 43% current smokers). To understand the relative efficacy of SFC and its components by GOLD stages, we conducted a post-hoc analysis of the TORCH dataset using baseline post-bronchodilator FEV1 to segment patients into three groups: moderate COPD (GOLD stage II and above: >or= 50%; n = 2156), severe COPD (GOLD stage III: 30% to < 50%; n = 3019) and very severe COPD (GOLD stage IV: < 30%; n = 937).Compared with placebo, SFC improved post-bronchodilator FEV1: 101 ml (95% confidence interval [CI]: 71, 132) in GOLD stage II, 82 ml (95% CI: 60, 104) in GOLD stage III and 96 ml (95% CI: 54, 138) in GOLD stage IV patients, and reduced the rate of exacerbations: 31% (95% CI: 19, 40) in GOLD stage II, 26% (95% CI: 17, 34) in GOLD stage III and 14% (95% CI: -4, 29) in GOLD stage IV. SFC improved health status to a greater extent than other treatments regardless of baseline GOLD stage. Similarly, SFC reduced the risk of death by 33% (hazard ratio [HR] 0.67; 95% CI: 0.45, 0.98) for GOLD stage II, 5% (HR 0.95; 95% CI: 0.73, 1.24) for GOLD stage III, and 30% (HR 0.70; 95% CI: 0.47, 1.05) for GOLD stage IV. The rates of adverse events were similar across treatment arms and increased with disease severity. Overall, there was a higher incidence of pneumonia in the fluticasone propionate and SFC arms, compared with other treatments in all GOLD stages.In the TORCH study, SFC reduced moderate-to-severe exacerbations and improved health status and FEV1 across GOLD stages. Treatment with SFC may be associated with reduced mortality compared with placebo in patients with GOLD stage II disease. The effects were similar to those reported for the study as a whole. Thus, SFC is an effective treatment option for patients with GOLD stage II COPD.Clinicaltrial.gov registration NCT00268216; Study number: SCO30003.

Project description:IntroductionChronic obstructive pulmonary disease (COPD) represents one of the leading causes of death worldwide. Published clinical trials suggest that the Chinese patent herbal medicine Shufeng Jiedu capsule (SFJD) is safe and may be effective for treating acute exacerbations of COPD (AECOPD). However, these effects have been reported with low or very low certainty evidence. This trial aims to evaluate the effectiveness and safety of SFJD for AECOPD.Methods and analysisThis study is designed as a multicentre, randomised, double-blind, placebo-controlled trial. Three hundred patients with moderate or severe hospitalised AECOPD will be recruited in Beijing, Shanghai and Hefei. Participants will be randomly assigned to SFJD and usual care or placebo and usual care at a ratio of 1:1. SFJD and placebo will be administered orally four capsules three times daily for 7 consecutive days followed by an 8-week follow-up period. The primary outcome will be COPD symptom severity as measured by the EXAcerbation of Chronic Pulmonary Disease Tool score. Secondary outcomes include clinical symptoms, quality of life, length of hospital stay, a total dose of antibiotics, the frequency of recurrence of AECOPD, haematological biomarkers, death and adverse events. This study will answer the question of whether SFJD was safe to use and will improve symptoms in people with AECOPD, and will therefore reduce the necessity for antibiotics, the risk and duration of admission to hospital, and the risk of recurrence.Ethics and disseminationThe ethics committee of the first affiliated hospital of Anhui Medical University, Beijing University of Chinese Medicine affiliated Dongzhimen hospital and fifth people's hospital of Shanghai Fudan University approved the study protocol. Informed written consent will be obtained from all the participants. The results of this trial will be disseminated at academic conferences and in peer-reviewed publications.Trial registration numberISRCTN99049821.

Project description:ObjectiveTo obtain evidence whether the online pulmonary rehabilitation(PR) programme 'my-PR' is non-inferior to a conventional face-to-face PR in improving physical performance and symptom scores in patients with COPD.DesignA two-arm parallel single-blind, randomised controlled trial.SettingThe online arm carried out pulmonary rehabilitation in their own homes and the face to face arm in a local rehabilitation facility.Participants90 patients with a diagnosis of chronic obstructive pulmonary disease (COPD), modified Medical Research Council score of 2 or greater referred for pulmonary rehabilitation (PR), randomised in a 2:1 ratio to online (n=64) or face-to-face PR (n=26). Participants unable to use an internet-enabled device at home were excluded.Main outcome measuresCoprimary outcomes were 6 min walk distance test and the COPD assessment test (CAT) score at completion of the programme.InterventionsA 6-week PR programme organised either as group sessions in a local rehabilitation facility, or online PR via log in and access to 'myPR'.ResultsThe adjusted mean difference for the 6 min walk test (6MWT) between groups for the intention-to-treat (ITT) population was 23.8 m with the lower 95% CI well above the non-inferiority threshold of -40.5 m at -4.5 m with an upper 95% CI of +52.2 m. This result was consistent in the per-protocol (PP) population with a mean adjusted difference of 15 m (-13.7 to 43.8). The CAT score difference in the ITT was -1.0 in favour of the online intervention with the upper 95% CI well below the non-inferiority threshold of 1.8 at 0.86 and the lower 95% CI of -2.9. The PP analysis was consistent with the ITT.ConclusionPR is an evidenced-based and guideline-mandated intervention for patients with COPD with functional limitation. A 6-week programme of online-supported PR was non-inferior to a conventional model delivered in face-to-face sessions in terms of effects on 6MWT distance, and symptom scores and was safe and well tolerated.
