Abstract
INTRODUCTION The climate crisis poses an immediate threat to human health and well-being, demanding urgent adaptions across sectors, including healthcare. The development of pressurized metered dose inhalers (MDIs) with greater sensitivity to the climate emergency using novel propellants with lower global warming potentials (GWPs), but comparable pharmacokinetic (PK) parameters to currently marketed MDIs, is a vital step toward reducing the impact of healthcare for respiratory disorders on climate change. This study evaluated the relative bioavailabilities of the individual components of a fixed-dose combination of budesonide/glycopyrrolate/formoterol fumarate (BGF) 160/9/4.8 μg per actuation between three different propellant formulations. METHODS Healthy male participants (aged 18-60 years) were randomized into a single-blind, three-period, single-dose, single-center, crossover study (NCT04600505). The PK and safety and tolerability profiles of BGF MDI formulated with two novel propellants with low GWP (hydrofluoroolefin-1234ze [HFO]; hydrofluorocarbon-152a [HFC]) were compared with BGF MDI formulated with the propellant used in the currently marketed reference product (hydrofluoroalkane-134a [HFA]). The study included a screening period, three treatment periods (with 3- to 7-day washout periods between each dose), and a follow-up. The primary PK parameters assessed were maximum observed plasma concentration (Cmax), area under the plasma concentration curve (AUC) from time zero extrapolated to infinity (AUCinf), and AUC from time zero to the time of the last quantifiable analyte concentration (AUClast). The study was not powered to statistically demonstrate bioequivalence. RESULTS Forty-seven participants completed the study, and 24 participants were evaluable for PK assessments. Systemic exposure, based on geometric mean ratios (90% confidence interval), to each BGF component from the test propellants delivered in a standard MDI was comparable with the reference propellant for AUClast (HFO vs. HFA: budesonide, 107.30 [94.53, 121.90]; glycopyrrolate, 106.10 [86.18, 130.60]; formoterol, 98.13 [86.44, 111.40]; HFC vs. HFA: budesonide, 98.80 [84.59, 115.40]; glycopyrrolate, 99.71 [80.84, 123.00]; formoterol, 107.00 [88.82, 128.90]); AUCinf (where evaluable) and Cmax followed the same trend. There were no serious adverse events or adverse events leading to treatment discontinuation. No new safety signals were observed. CONCLUSIONS Systemic BGF component exposure was similar for both test propellants (HFO and HFC) compared with the HFA reference propellant, with an acceptable safety profile in the studied population. Therefore, both novel low GWP propellants show strong potential as candidates for development of MDIs with greater sensitivity to the climate crisis, a vital step toward ameliorating the detrimental impact of healthcare on the environment. Further investigation in larger studies is warranted.

Abstract
Purpose Blood eosinophil (EOS) count can guide treatment decisions for chronic obstructive pulmonary disease (COPD). In the 52-week ETHOS study (NCT02465567), budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) triple therapy at two inhaled corticosteroid doses reduced moderate/severe exacerbation rates and improved lung function, symptoms, and disease-related quality of life (QoL) versus dual therapy with glycopyrronium/formoterol fumarate dihydrate (GFF) or budesonide/formoterol fumarate dihydrate (BFF) in patients with moderate-to-very severe COPD. This subgroup analysis evaluated treatment benefits in ETHOS by baseline EOS count. Methods Patients (40-80 years) with a COPD history were randomly assigned 1:1:1:1 to receive BGF 320/14.4/10 µg, BGF 160/14.4/10 µg, GFF 14.4/10 µg, or BFF 320/10 µg via a metered-dose inhaler. This post-hoc analysis assessed endpoints by baseline EOS count using Global Initiative for Obstructive Lung Disease thresholds (<100, ≥100, ≥100-<300, ≥300 cells/mm3), and investigated continuous relationships between treatment effects and EOS count on exacerbations, symptoms, disease-related QoL, lung function, and safety. Results In the modified intention-to-treat population (n=8509), 82.6% had EOS counts ≥100 cells/mm3. BGF 320 reduced moderate/severe exacerbation rates versus GFF in the ≥100, ≥100-<300, and ≥300 subgroups; treatment differences increased with EOS count. BGF 320 improved rescue medication use and lung-function outcomes across all subgroups, and St George's Respiratory Questionnaire total score, Transition Dyspnea Index focal score, and Exacerbations of Chronic Pulmonary Disease Tool total score in all except the <100 subgroup versus GFF. Benefits of BGF 320 versus BFF were generally consistent across subgroups. Safety data were comparable across subgroups. Conclusion Benefits of BGF versus GFF were observed across EOS counts, particularly at ≥100 cells/mm³; versus BFF, benefits were largely independent of EOS. These findings confirm that benefits of ICS-containing triple therapy are not restricted to EOS counts ≥300 cells/mm³, supporting recommendations to consider triple therapy in patients with an exacerbation history and EOS counts ≥100 cells/mm³.

Abstract
BACKGROUND The major drivers of cost-effectiveness for chronic obstructive pulmonary disease (COPD) therapies are the occurrence of exacerbations and deaths. Exacerbations, including acute and long-term events, can cause worsening of COPD and lead to an increased risk of further exacerbations, and ultimately may elevate the risk of death. In contrast to this, health economic models are based on COPD severity progression. In this post hoc analysis of the ETHOS study, we focus on the progression of COPD due to exacerbations and deaths. METHODS We fitted semi-parametric and fully parametric multi-state Markov models with the following five progressive states: State 1, no exacerbation; State 2, 1 moderate exacerbation; State 3, ≥ 2 moderate exacerbations; State 4, ≥ 1 severe exacerbations; State 5, death. The models only allowed a patient to transition to a worsened health state, and transitions did not necessarily have to be to the next adjacent state. We used the multi-state models to analyse data from ETHOS, a phase III, 52-week study assessing the efficacy and safety of triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate in moderate-to-very severe COPD. RESULTS The Weibull multi-state Markov model showed good fit of the data. In line with clinical evidence, we found a higher mortality risk after a severe exacerbation (11.4-fold relative ratio increase [95% CI, 7.7-17.0], 6.4-fold increase [95% CI, 3.8-10.8] and 5.4-fold increase [95% CI, 2.9-10.3] relative to no exacerbations, 1 moderate exacerbation or ≥ 2 moderate exacerbations, respectively). One moderate exacerbation increased mortality risk 1.8-fold (95% CI, 1.1-2.9) vs no exacerbations. We also found a higher risk of severe exacerbation and mortality following ≥ 2 moderate exacerbations. CONCLUSION Multi-state modelling of patients with COPD in ETHOS found an acute and chronic effect of severe exacerbations on mortality risk. Risk was also increased after a moderate exacerbation. Clinical management with effective pharmacotherapies should be optimised to avoid even moderate exacerbations. Modelling with exacerbations could be an alternative to current COPD models focused on disease progression. TRIAL REGISTRATION NCT02465567.

Abstract
Introduction Velsecorat (AZD7594) is a non-steroidal, selective, glucocorticoid receptor modulator (SGRM), being developed for the treatment of asthma. This article reports the initial, first-in-human, single and repeat dose-escalating study in healthy male volunteers. Methods The study comprised two parts, a single ascending dose part (n=47) and a multiple ascending dose part (n=26). Inhaled velsecorat was administered by nebulization as one single dose in the first part of the study and as a single dose with subsequent multiple daily doses (day 5–16) for 12 days once daily in the second part of the study. At each dose level, participants were randomized to velsecorat (n=6) or placebo (n=2/3). The safety, pharmacokinetics (PK) and pharmacodynamics (PD) of velsecorat were evaluated. Results Inhaled velsecorat was safe and well tolerated up to and including the highest dose tested (1872 µg). Plasma exposure suggested dose proportional PK. The terminal half-life following repeated dosing was 25–31 hours and steady state conditions for velsecorat in plasma were generally reached within 4 doses. The accumulation ratio was low (≤2), and data did not indicate any time-dependent PK. There were dose-related effects on 24-hour plasma cortisol, plasma cortisol after ACTH stimulation and osteocalcin, systemic PD markers of glucocorticoid activity. There were no effects on other biomarkers tested (DHEA-S and 4βOH-cholesterol). Conclusion The early clinical evaluation of inhaled velsecorat suggests that this novel SGRM is well tolerated in the dose range investigated. It shows dose proportional plasma exposure, low accumulation, and has dose-dependent effects on markers of glucocorticoid activity.

Abstract
Background and aims: Low peak inspiratory flow (PIF) is common following severe exacerbations of
chronic obstructive pulmonary disease (COPD). Patients with COPD and low PIF
may be at risk of suboptimal delivery of inhaled therapies to the airways,
especially when using devices such as dry powder inhalers (DPIs), which
require greater inspiratory effort than metered dose inhalers (MDIs). We
report the results from a 2-week crossover study evaluating the effects of
inhaled dual therapy with budesonide/formoterol fumarate dihydrate with an
MDI with a spacer versus a DPI in patients with COPD and
low PIF. Methods: This randomized, open-label, two-period (each 1 week in duration) crossover
efficacy and safety study included patients with severe-to-very severe COPD
and PIF < 50 L/min (NCT04078126). Patients were randomized 1:1 to
twice-daily budesonide/formoterol fumarate dihydrate MDI (BFF MDI) 320/10 µg
with a spacer for 1 week followed by twice-daily budesonide/formoterol
fumarate dihydrate DPI (BUD/FORM DPI) 320/9 µg for 1 week, or the inverse.
The primary endpoint was peak change from baseline in forced expiratory
volume in 1 s (FEV1) within 4 h post-dose following 1 week of
treatment. Other assessments included pre-dose lung function,
pharmacokinetics, and safety, as assessed by adverse events. Results: The modified intention-to-treat analysis set comprised 30 patients (mean age:
66.9 years; mean baseline FEV1: 766 mL; mean COPD assessment test
score: 22.20). Following 1 week of treatment, both BFF MDI and BUD/FORM DPI
improved mean [95% confidence interval (CI)] peak FEV1 4 h
post-dose [256 (190, 322) mL and 274 (208, 340) mL, respectively]. No
clinically meaningful difference between treatments was observed for any
lung function endpoint. There were no unexpected safety findings. Conclusion: Dual therapy with BFF MDI and with BUD/FORM DPI led to improvements in lung
function in patients with severe-to-very severe COPD and low PIF.

Abstract
BACKGROUND Triple therapy with inhaled corticosteroids/long-acting muscarinic antagonists/long-acting β2-agonists (ICS/LAMA/LABA) is recommended for patients with chronic obstructive pulmonary disease (COPD) with continued symptoms or exacerbations, despite treatment with LAMA/LABA or ICS/LABA. The pulmonary, extrathoracic, and regional lung deposition patterns of a radiolabeled ICS/LAMA/LABA triple fixed-dose combination budesonide/glycopyrrolate/formoterol fumarate (BGF 320/18/9.6 μg), delivered via a single Aerosphere metered dose inhaler (MDI) were previously assessed in healthy volunteers and showed good deposition to the central and peripheral airways (whole lung deposition: 37.7%). Here, we report the findings assessing BGF in patients with moderate-to-very severe COPD. METHODS This phase I, single-dose, open-label gamma scintigraphy imaging study (NCT03906045) was conducted in patients with moderate-to-very severe COPD. Patients received two actuations of BGF MDI (160/9/4.8 μg per actuation) radiolabeled with technetium‑99‑pertechnetate, not exceeding 5 MBq per actuation. Immediately following each inhalation, patients performed a breath-hold of up to 10 s, then exhaled into an exhalation filter. Gamma scintigraphy imaging of the anterior and posterior views of the lungs and stomach, and a lateral head and neck view, were performed immediately after exhalation. The primary objective of the study was to assess the pulmonary deposition of BGF. Secondary objectives assessed the deposited dose of radiolabeled BGF in the oropharyngeal and stomach regions, on the actuator, and on the exhalation filter in addition to regional airway deposition patterns in the lungs. RESULTS The mean BGF emitted dose deposited in the lungs was 32.1% (standard deviation [SD] 15.6) in patients with moderate-to-very severe COPD, 35.2% (SD 12.8) in patients with moderate COPD, and 28.7% (SD 18.4) in patients with severe/very severe COPD. Overall, the mean normalized outer/inner ratio was 0.55 (SD 0.19), while the standardized central/peripheral ratio was 2.21 (SD 1.64). CONCLUSIONS Radiolabeled BGF 320/18/9.6 μg was efficiently delivered and deposited throughout the entire lung, including large and small airways, in patients with moderate-to-very severe COPD, with similar deposition in patients with moderate COPD and patients with severe/very severe COPD.

Abstract
BACKGROUND In the phase III, 52-week ETHOS study in patients with moderate to very severe chronic obstructive pulmonary disease (COPD), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF), at two inhaled corticosteroid dose levels, resulted in significantly lower moderate/severe exacerbation rates versus glycopyrrolate/formoterol fumarate (GFF) and budesonide/formoterol fumarate (BFF). Here, we report results from the ETHOS pulmonary function test (PFT) sub-study, which assessed lung function in a subset of ETHOS patients. METHODS ETHOS (NCT02465567) was a randomized, double-blind, multi-center, parallel-group study in patients with moderate to very severe COPD who had experienced ⩾1 moderate/severe exacerbation in the previous year. Patients received BGF 320/18/9.6 µg, BGF 160/18/9.6 μg, GFF 18/9.6 µg, or BFF 320/9.6 µg twice daily via a single metered dose Aerosphere inhaler for 52 weeks. A subset of patients participated in the 4-hour PFT sub-study; primary endpoints were change from baseline in morning pre-dose trough forced expiratory volume in one second (FEV1) versus GFF and FEV1 area under the curve from 0 to 4 hours (AUC0-4) versus BFF at week 24. RESULTS The PFT modified intent-to-treat population included 3088 patients (mean age 64.4 years; mean reversibility post-albuterol 16.7%; mean post-albuterol FEV1% predicted 42.8). BGF 320/18/9.6 µg and 160/18/9.6 µg significantly improved morning pre-dose trough FEV1 at week 24 versus GFF (p ⩽ 0.0035 for both). Improvements in trough FEV1 were also observed at week 52 for BGF 320/18/9.6 µg and 160/18/9.6 µg versus GFF (p ⩽ 0.0005 for both). For FEV1 AUC0-4 at week 24, BGF 320/18/9.6 µg and 160/18/9.6 µg showed significant improvements versus BFF (p < 0.0001 for both). Improvements were maintained at week 52 (p < 0.0001). CONCLUSIONS BGF 320/18/9.6 µg and 160/18/9.6 µg significantly improved trough FEV1 versus GFF and FEV1 AUC0-4 versus BFF at week 24. The lung function benefits with both doses of BGF were maintained following 52 weeks of treatment.The reviews of this paper are available via the supplemental material section.

Abstract
Background For patients with chronic obstructive pulmonary disease (COPD), greater improvements in lung function have been demonstrated for triple versus dual inhaled therapies in traditional spirometry studies. This study was the first to use functional respiratory imaging (FRI), known for increased sensitivity to airway changes versus spirometry, to assess the effect of the inhaled corticosteroid (ICS) component (budesonide) on lung function in patients with moderate-to-severe COPD and a blood eosinophil count > 150 cells/mm3. Methods Patients in this Phase IIIb (NCT03836677), randomized, double-blind, crossover study received twice-daily budesonide/glycopyrrolate/formoterol fumarate (BGF) 320/18/9.6 μg fixed-dose triple therapy and glycopyrrolate/formoterol fumarate (GFF) 18/9.6 μg fixed-dose dual therapy over 4 weeks, each delivered via a single metered dose Aerosphere inhaler. Primary endpoints were the improvements from baseline for each treatment in specific (i.e. corrected for lobar volume) image-based airway volume (siVaw) and resistance (siRaw) measured via FRI taken at total lung capacity (Day 29). Secondary outcomes included spirometry and body plethysmography. Adverse events were monitored throughout the study. Results A total of 23 patients were randomized and included in the intent-to-treat analysis (mean age 64.9 years, 78.3% males, 43.5% current smokers, mean predicted post-bronchodilator forced expiratory volume in 1 s [FEV1] 63.6%). BGF and GFF both statistically significantly increased siVaw from baseline at Day 29 (geometric mean ratio [GM], 95% confidence interval [CI]: 1.72 [1.38, 2.13] and 1.53 [1.28, 1.83], respectively, both p < 0.0001), with a greater increase observed for BGF versus GFF (GM, 95% CI 1.09 [1.03, 1.16], p = 0.0061). Statistically significant reductions in siRaw were also observed with both BGF and GFF (GM, 95% CI 0.50 [0.39, 0.63] and 0.52 [0.40, 0.67], respectively, both p < 0.0001). Additionally, significant improvements from baseline in post-dose FEV1 were observed with BGF and GFF (mean 346 mL, p = 0.0003 and 273 mL, p = 0.0004, respectively). Safety findings were consistent with the known profiles of BGF and GFF. Conclusions As observed using FRI, triple therapy with BGF resulted in greater increases in airway volume, and reductions in airway resistance versus long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) dual therapy with GFF, reflecting the ICS component’s contribution in patients with moderate-to-severe COPD.

Abstract
Rationale: In the phase III, 52-week ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial in chronic obstructive pulmonary disease (COPD) (NCT02465567), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) significantly reduced all-cause mortality compared with glycopyrrolate/formoterol fumarate (GFF). However, 384 of 8,509 patients were missing vital status at Week 52 in the original analyses.Objectives: To assess the robustness of the ETHOS mortality findings after additional data retrieval for patients missing Week 52 vital status in the original analyses.Methods: Patients with moderate to very severe COPD and prior history of exacerbation received twice-daily dosing with 320/18/9.6 μg of BGF (BGF 320), 160/18/9.6 μg of BGF (BGF 160), 18/9.6 μg of GFF, or 320/9.6 μg of budesonide/formoterol fumarate (BFF) (all delivered via a single metered-dose Aerosphere inhaler). Time to death (all-cause) was a prespecified secondary endpoint.Measurements and Main Results: In the final retrieved dataset, which included Week 52 vital status for 99.6% of the intent-to-treat population, risk of death with BGF 320 was significantly lower than GFF (hazard ratio, 0.51; 95% confidence interval, 0.33-0.80; unadjusted P = 0.0035). There were no significant differences in mortality when comparing BGF 320 with BFF (hazard ratio, 0.72; 95% confidence interval, 0.44-1.16; P = 0.1721), nor were significant differences observed when comparing BGF 160 against either dual comparator. Results were similar when the first 30, 60, or 90 days of treatment were excluded from the analysis. Deaths from cardiovascular causes occurred in 0.5%, 0.8%, 1.4%, and 0.5% of patients in the BGF 320, BGF 160, GFF, and BFF groups, respectively.Conclusions: Using final retrieved vital status data, triple therapy with BGF 320 reduced the risk of death compared with GFF, but was not shown to significantly reduce the risk of death compared with BFF, in patients with COPD. Triple therapy containing a lower dose of inhaled corticosteroid (BGF 160) was not shown to significantly reduce the risk of death compared with the dual therapy comparators.

Abstract
Purpose In the Phase III, 24-week KRONOS study (NCT02497001), triple therapy with budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) reduced exacerbation rates versus glycopyrrolate/formoterol fumarate (GFF) MDI in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD) and no requirement for a history of exacerbations. We report a post hoc analysis investigating whether the benefits observed were driven by patients with ≥1 exacerbation in the 12 months prior to the study. Patients and Methods Patients received BGF MDI 320/18/9.6 µg, GFF MDI 18/9.6 µg, budesonide/formoterol fumarate (BFF) MDI 320/9.6 µg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12 µg twice-daily. Post hoc analyses were conducted on exacerbation and lung function results from patients with and without a documented exacerbation in the 12 months prior to the study. Results Overall, 74% (1411/1896) of the modified-intent-to-treat (mITT) population had no moderate/severe exacerbations in the 12 months prior to the study. BGF MDI reduced exacerbation rates versus GFF MDI in the prior (58%; unadjusted p=0.0003) and no prior (48%; unadjusted p=0.0001) exacerbations subgroups. The magnitude of reduction in exacerbation rates was generally similar within subgroups for BGF MDI versus BFF MDI and BUD/FORM DPI. In the prior exacerbations subgroup, risk during treatment for time to first exacerbation was lower with BGF MDI versus GFF MDI (p=0.0022) and BFF MDI (p=0.0110); excluding the first 30 days of data yielded similar results. The magnitude of reduction in exacerbation rates for BGF MDI compared with GFF MDI increased with eosinophil count. Conclusion In patients with or without a history of exacerbations in the 12 months prior to the study, BGF MDI reduced exacerbation rates versus GFF MDI, suggesting results observed in the overall population were not driven by the small subgroup with a prior history of exacerbations.

Abstract
This gamma scintigraphy imaging study assessed pulmonary, extrathoracic and regional lung deposition patterns of a radiolabelled inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist triple fixed-dose combination budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF 320/14.4/10 μg), delivered by pressurised metered dose inhaler (pMDI) using innovative co-suspension delivery technology (Aerosphere™). In this Phase I, randomised, single-centre, single-dose, two-period, crossover study (NCT03740373), 10 healthy male adults received two actuations of BGF MDI (160/7.2/4.8 μg per actuation) radiolabelled with 99mTc, not exceeding 5 MBq per actuation. Immediately following each inhalation, subjects performed a 10- or 3-second breath-hold, then exhaled into an exhalation filter. The primary objective was to assess the pulmonary deposition of BGF MDI following the 10-second breath-hold. The secondary objectives were to assess deposition after the 3-second breath-hold and lung regional and extrathoracic deposition after each breath-hold length. Imaging of the lungs, stomach, head and neck was recorded by gamma scintigraphy immediately after exhalation. The mean BGF MDI emitted dose deposited in the lungs was 37.7% for the 10-second breath-hold and 34.5% for the 3-second breath-hold. Emitted dose detected in the exhalation filter was ≤0.4% for both breath-hold lengths. The mean normalised peripheral/central ratio was 0.65 and 0.75 for the 10- and 3-second breath-holds, respectively, while the standardised central/peripheral ratios were 1.79 and 1.40, respectively. There were no new or unexpected safety findings. In conclusion, BGF MDI was efficiently deposited in the central and the peripheral regions of the lungs, with similar regional deposition patterns following a 10- and 3-second breath-hold.

Abstract
BACKGROUND Triple fixed-dose regimens of an inhaled glucocorticoid, a long-acting muscarinic antagonist (LAMA), and a long-acting β2-agonist (LABA) for chronic obstructive pulmonary disease (COPD) have been studied at single dose levels of inhaled glucocorticoid, but studies at two dose levels are lacking. METHODS In a 52-week, phase 3, randomized trial to evaluate the efficacy and safety of triple therapy at two dose levels of inhaled glucocorticoid in patients with moderate-to-very-severe COPD and at least one exacerbation in the past year, we assigned patients in a 1:1:1:1 ratio to receive twice-daily inhaled doses of triple therapy (inhaled glucocorticoid [320 μg or 160 μg of budesonide], a LAMA [18 μg of glycopyrrolate], and a LABA [9.6 μg of formoterol]) or one of two dual therapies (18 μg of glycopyrrolate plus 9.6 μg of formoterol or 320 μg of budesonide plus 9.6 μg of formoterol). The primary end point was the annual rate (the estimated mean number per patient per year) of moderate or severe COPD exacerbations, as analyzed in the modified intention-to-treat population with the use of on-treatment data only. RESULTS The modified intention-to-treat population comprised 8509 patients. The annual rates of moderate or severe exacerbations were 1.08 in the 320-μg-budesonide triple-therapy group (2137 patients), 1.07 in the 160-μg-budesonide triple-therapy group (2121 patients), 1.42 in the glycopyrrolate-formoterol group (2120 patients), and 1.24 in the budesonide-formoterol group (2131 patients). The rate was significantly lower with 320-μg-budesonide triple therapy than with glycopyrrolate-formoterol (24% lower: rate ratio, 0.76; 95% confidence interval [CI], 0.69 to 0.83; P<0.001) or budesonide-formoterol (13% lower: rate ratio, 0.87; 95% CI, 0.79 to 0.95; P = 0.003). Similarly, the rate was significantly lower with 160-μg-budesonide triple therapy than with glycopyrrolate-formoterol (25% lower: rate ratio, 0.75; 95% CI, 0.69 to 0.83; P<0.001) or budesonide-formoterol (14% lower: rate ratio, 0.86; 95% CI, 0.79 to 0.95; P = 0.002). The incidence of any adverse event was similar across the treatment groups (range, 61.7 to 64.5%); the incidence of confirmed pneumonia ranged from 3.5 to 4.5% in the groups that included inhaled glucocorticoid use and was 2.3% in the glycopyrrolate-formoterol group. CONCLUSIONS Triple therapy with twice-daily budesonide (at either the 160-μg or 320-μg dose), glycopyrrolate, and formoterol resulted in a lower rate of moderate or severe COPD exacerbations than glycopyrrolate-formoterol or budesonide-formoterol.

Abstract
Background Budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) is a triple fixed-dose combination for COPD. The long-term safety of triple therapy for COPD has not been investigated in Japanese patients. In this 28-week extension study (NCT03262012), we investigated the long-term safety and tolerability of BGF MDI in Japanese patients with moderate-to-very severe COPD who completed the 24-week Phase III randomized, double-blind, multicenter KRONOS study (NCT02497001). Materials and methods Patients randomized to BGF MDI 320/18/9.6 μg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6 μg, budesonide/formoterol fumarate (BFF) MDI 320/9.6 μg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12 μg twice-daily in KRONOS continued treatment for up to 28 additional weeks. Safety was evaluated over 52 weeks via adverse event (AE) monitoring, electrocardiograms, clinical laboratory testing, and vital sign measurements. Results The safety population included 416 patients who received BGF MDI (n=139), GFF MDI (n=138), BFF MDI (n=70), or BUD/FORM DPI (n=69). Treatment-emergent AE (TEAE) rates were similar across treatment groups (range: 82.6-82.9%). The most frequent TEAEs overall were nasopharyngitis (32.2%) and bronchitis (9.9%). The incidence of major adverse cardiovascular events was low across groups (range: 0.0-2.9%). Over 52 weeks, the incidence of confirmed pneumonia was 9.4% (BGF MDI), 3.6% (GFF MDI), 5.7% (BFF MDI), and 2.9% (BUD/FORM DPI); in the 28-week extension period, rates were comparable across groups (range: 2.9-5.7%). Six deaths were reported (0.7-2.2% per group); none were considered treatment-related. No clinically meaningful trends were observed in electrocardiograms, laboratory parameters, or vital signs over time in any of the treatment groups. Conclusion All treatments were well tolerated over 52 weeks, and the safety profile of BGF MDI was generally comparable to dual long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) and inhaled corticosteroid (ICS)/LABA therapies. These findings support the long-term tolerability of BGF MDI in Japanese patients with COPD.

Abstract
Background KRONOS, a Phase III, multicenter, randomized, double-blind study (NCT02497001) conducted in Canada, China, Japan, and the USA, assessed the efficacy and safety of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI), a triple fixed-dose combination therapy, relative to dual therapies in patients with moderate-to-very severe COPD. Here we present findings from the Japanese subgroup of KRONOS. Methods Patients received BGF MDI 320/18/9.6μg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6μg, budesonide/formoterol fumarate (BFF) MDI 320/9.6μg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12μg twice-daily for 24 weeks. The primary endpoint was the change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over Weeks 12-24. Symptoms, quality of life, exacerbations, and safety were also assessed. Results In total, 416 Japanese patients (21.9% of the global KRONOS population) were randomized and treated with BGF MDI (n=139), GFF MDI (n=138), BFF MDI (n=70), or BUD/FORM DPI (n=69). Nominally significant improvements in the change from baseline in morning pre-dose trough FEV1 over Weeks 12-24 were observed for BGF MDI vs GFF MDI (least squares mean [LSM] difference 37 mL, 95% confidence interval [CI] 3, 72; P=0.0337) and BFF MDI (67 mL; 95% CI 25, 109; P=0.0020). Treatment with BGF MDI led to a nominally significant reduction in the rate of moderate/severe exacerbations vs GFF MDI (rate ratio 0.40, 95% CI 0.19, 0.83; P=0.0142). Compared with dual therapies, numerical improvements were observed with BGF MDI for Transition Dyspnea Index focal score and the change from baseline in Evaluating Respiratory Symptoms in COPD total score (P≤0.3899). All treatments were generally well tolerated. Conclusion BGF MDI nominally significantly improved lung function and numerically improved symptoms vs GFF MDI and BFF MDI. BGF MDI nominally significantly reduced exacerbations vs GFF MDI in Japanese patients with COPD. Efficacy and safety findings were generally comparable to those in the global KRONOS population.

Abstract
Purpose Accessorized prefilled syringes (APFS) have demonstrated functionality and reliability for subcutaneous (SC) delivery, including self-administration, of benralizumab 30 mg in the clinic or at home. The multicenter, open-label GRECO study (NCT02918071) assessed functionality and reliability of a single-use autoinjector (AI) for at-home benralizumab administration by patients or their caregivers. Patients and methods Adults with severe asthma received benralizumab SC injections at the study site at Weeks 0, 4, and 8. The first dose was administered by health care providers. Patients/caregivers had the option of administering the second dose and were required to administer the third dose under supervision. At Weeks 12 and 16, patients/caregivers administered benralizumab via AI at home. After each administration, patients/caregivers completed questionnaires concerning administration and device functioning. All AI devices used were returned for evaluation. Results A total of 595 AIs were used for 121 patients (mean age 48.5 years; 64% female) in the clinic and at home. Of 116 participants, 113 (97.4%; 95% confidence interval [CI]: 92.63–99.46) and 112 (96.6%; 95% CI: 91.41–99.05) successfully administered benralizumab at home at Weeks 12 and 16, respectively; 108 (93.1%; 95% CI: 86.86–96.98) were successful on both occasions. Throughout the study, 10 (1.7%) AI administrations were unsuccessful: 8 (1.3%) because of user error, 1 (0.2%) with undetermined cause, and 1 (0.2%) because of a manufacturing defect. Benralizumab efficacy (assessed by Asthma Control Questionnaire 6 score) and pharmacokinetics for patients using the AI were comparable to published results for patients receiving benralizumab via syringe in a clinical setting. No new or unexpected safety findings were observed. Conclusion AIs were functional, reliable, and performed well in the clinic and at home. Nearly all patients and caregivers successfully administered SC benralizumab via AI. Benralizumab availability in AI and APFS could provide patients with choices for self-administration.

Abstract
OBJECTIVE We compared the pharmacokinetic exposure following a single subcutaneous dose of benralizumab 30 mg using either autoinjectors (AI) or accessorized prefilled syringes (APFS). APFS and AI functionality and reliability for at-home benralizumab delivery have been demonstrated in the GREGALE and GRECO studies, respectively. METHODS In the open-label AMES study (NCT02968914), 180 healthy adult men and women were randomized to one of two device (AI or APFS) and three injection site (upper arm, abdomen, or thigh) combinations. Randomization was stratified by weight (<70 kg, 70-84.9 kg, and ≥85 kg). Blood eosinophil counts were measured on Days 1, 8, 29, and 57. RESULTS Benralizumab pharmacokinetic exposure was similar between AI and APFS. Geometric mean ratios (AI/APFS) (90% CI) were 92.8% (87.4-98.6) and 94.5% (88.2-101.2) for two area under the concentration‒time curve measurements (AUClast and AUCinf). Benralizumab exposure was approximately 15-30% greater for thigh vs. abdomen or upper arm administration. Exposure was slightly greater for APFS vs. AI regardless of injection site or weight class. These differences were unlikely to be clinically relevant, as eosinophil depletion was achieved consistently with both devices at all injection sites. No device malfunctions were reported. No new or unexpected safety findings were observed. CONCLUSION Benralizumab pharmacokinetic exposure was similar between AI and APFS, with consistent blood eosinophil count depletion observed with both devices. These results support benralizumab administration with either AI or APFS, providing patients and physicians increased choice, flexibility, and convenience for potential at-home delivery.

Abstract
BACKGROUND Inhaled corticosteroids have been used in patients with chronic obstructive pulmonary disease (COPD), but the potential benefits of their use in triple therapy are not well known. We aimed to compare the efficacy of a triple therapy with corresponding dual therapies in symptomatic patients with moderate to very severe COPD, without a requirement for a history of exacerbations. METHODS In this double-blind, parallel-group, multicentre phase 3 randomised controlled trial, we recruited patients from hospitals and care centres in Canada, China, Japan, and the USA. Eligible patients were 40-80 years of age, were current or former smokers (with a smoking history of ≥10 pack-years), had an established clinical history of COPD, and were symptomatic for COPD, despite receiving two or more inhaled maintenance therapies for at least 6 weeks before screening. We randomly assigned patients (2:2:1:1) using an interactive web response system to receive budesonide/glycopyrrolate/formoterol fumarate metered-dose inhaler 320/18/9·6 μg (BGF MDI), glycopyrrolate/ formoterol fumarate metered-dose inhaler 18/9·6 μg (GFF MDI), budesonide/formoterol fumarate metered-dose inhaler 320/9·6 μg (BFF MDI), or open-label budesonide/formoterol fumarate dry-powder inhaler 400/12 μg (BUD/ FORM DPI). Primary endpoints for the Europe/Canada statistical analysis approach were FEV1 area under the curve from 0-4 h (AUC0-4) for BGF MDI versus BFF MDI and BGF MDI versus BUD/FORM DPI over 24 weeks; and change from baseline in morning pre-dose trough FEV1 for BGF MDI versus GFF MDI and non-inferiority of BFF MDI versus BUD/FORM DPI (margin of -50 mL from lower bound of 95% CI) over 24 weeks. Comparisons with BUD/FORM DPI were made for the Europe/Canada statistical analysis approach only. This study is registered with ClinicalTrials.gov, number NCT02497001. FINDINGS Between Aug 20, 2015, and Jan 5, 2018, 3047 patients were screened from 215 sites, and 1902 were randomly assigned to receive BGF MDI (n=640), GFF MDI (n=627), BFF MDI (n=316), or BUD/FORM DPI (n=319). Over 24 weeks, BGF MDI significantly improved FEV1 AUC0-4 versus BFF MDI (least squares mean difference 104 mL, 95% CI 77 to 131; p<0·0001) and BUD/FORM DPI (91 mL, 64 to 117; p<0·0001). BGF MDI also significantly improved pre-dose trough FEV1 versus GFF MDI (22 mL, 4 to 39; p=0·0139) and was non-inferior to BUD/FORM DPI (-10 mL, -36 to 16; p=0·4390). At week 24, patients in the BGF MDI group had a significantly improved FEV1 AUC0-4 compared with patients receiving BFF MDI (116 mL, 95% CI 80 to 152; p<0·0001); there was a non-significant improvement in the change from baseline in morning pre-dose trough FEV1 at week 24 versus GFF MDI (13 mL, -9 to 36 mL; p=0·2375). The most common treatment-emergent adverse events were nasopharyngitis (n=49 [8%] in the BGF MDI group; n=41 [7%] in the GFF MDI group; n=26 [8%] in the BFF MDI group; and n=30 [9%] in the BUD/FORM DPI group) and upper respiratory tract infection (n=65 [10%]; n=38 [6%]; n=18 [6%]; and n=22 [7%]). Pneumonia incidence was low (<2%) and similar across treatments. There were two treatment-related deaths, both in the GFF MDI group. INTERPRETATION BGF MDI was efficacious, well tolerated, and could be a more appropriate treatment than the corresponding dual therapies for symptomatic patients with moderate to very severe COPD, irrespective of exacerbation history.

Abstract
BACKGROUND In the Phase III CALIMA trial, benralizumab significantly reduced asthma exacerbations, increased lung function, and alleviated symptoms for patients with severe, uncontrolled eosinophilic asthma. The aim of this subgroup analysis was to evaluate the efficacy and safety of benralizumab for Japanese patients in the CALIMA trial. METHODS CALIMA was a randomised, controlled trial of 1306 patients (aged 12-75 years; registered at ClinicalTrials.gov: NCT01914757) with severe asthma uncontrolled by medium- to high-dosage inhaled corticosteroids and long-acting β2-agonists (ICS/LABA). Patients received 56 weeks' benralizumab 30 mg either every 4 weeks (Q4W) or every 8 weeks (Q8W; first three doses Q4W), or placebo Q4W. The primary analysis population was patients receiving high-dosage ICS/LABA with blood eosinophils ≥300 cells/μL. This subgroup analysis covered Japanese patients from this group. RESULTS Of 83 patients randomised in Japan, 46 were receiving high-dosage ICS/LABA and had blood eosinophils ≥300 cells/μL. Compared with placebo, benralizumab reduced the annual rate of asthma exacerbations by 66% (Q4W; rate ratio 0.34, 95% CI, 0.11-0.99) and 83% (Q8W; rate ratio 0.17, 95% CI, 0.05-0.60); increased prebronchodilator FEV1 by 0.334 L (Q4W; 95% CI, 0.020-0.647) and 0.198 L (Q8W; 95% CI, -0.118 to 0.514); and decreased total asthma symptom score by 0.17 (Q4W; 95% CI, -0.82 to 0.48) and 0.24 (Q8W; 95% CI, -0.87 to 0.40). Percentages of adverse events were consistent with the overall CALIMA group. CONCLUSIONS Benralizumab reduced annual asthma exacerbations and symptoms, increased lung function, and was well-tolerated by Japanese patients with severe, uncontrolled eosinophilic asthma.

Abstract
AZD5423 is a novel, inhaled, selective glucocorticoid receptor modulator (SGRM), which in an allergen challenge model in asthma patients improved lung function and airway hyper-reactivity. In the current trial, AZD5423 was for the first time tested in patients with chronic obstructive pulmonary disease (COPD). In this double-blind, randomized and parallel group study, we examined airway and systemic effects of two doses of AZD5423, inhaled via Turbuhaler for 12 weeks, in 353 symptomatic patients with COPD (average pre-bronchodilator forced expiratory volume in one-second (FEV1) at screening was 50-52% of predicted normal). Pre-bronchodilator FEV1 was primary variable, with other lung function parameters plus symptoms and 24-hr plasma cortisol being secondary variables. Plasma concentrations of AZD5423 were also measured. Effects were compared against placebo and a reference glucocorticoid receptor agonist control. Neither AZD5423, at doses which have shown to be efficacious in allergen-induced asthma, nor the reference control, at double the approved dose, had any clinically meaningful effect in the patient population studied in regard to lung function or markers of inflammation. Both GR modulators were well tolerated and did suppress 24-hr cortisol. This study suggests that the selected population of patients with COPD does not respond to treatment with AZD5423 as regards lung function, while showing the expected systemic effects. It cannot be ruled out that a favourable lung function response of AZD5423 can be evoked using another experimental setting and/or within a different population of patients with COPD.

Abstract
BACKGROUND Benralizumab is a humanised, afucosylated, anti-interleukin-5 receptor α monoclonal antibody that induces direct, rapid, and nearly complete depletion of eosinophils. We aimed to assess the efficacy and safety of benralizumab as add-on therapy for patients with severe, uncontrolled asthma and elevated blood eosinophil counts. METHODS In this randomised, double-blind, parallel-group, placebo-controlled, phase 3 study (CALIMA) undertaken at 303 sites in 11 countries, we enrolled patients aged 12-75 years with severe asthma uncontrolled by medium-dosage to high-dosage inhaled corticosteroids plus long-acting β₂-agonists (ICS plus LABA) and a history of two or more exacerbations in the previous year. Patients were randomly assigned (1:1:1) to receive 56 weeks of benralizumab 30 mg every 4 weeks (Q4W), benralizumab 30 mg every 8 weeks (Q8W; first three doses 4 weeks apart), or placebo (all subcutaneous injection). Patients were stratified (2:1) by baseline blood eosinophil counts 300 cells per μL or greater and less than 300 cells per μL, respectively. Patients and study centre staff were masked to treatment allocation. The primary endpoint was annual exacerbation rate ratio versus placebo for patients receiving high-dosage ICS plus LABA with baseline blood eosinophils 300 cells per μL or greater (intention-to-treat analysis). Key secondary endpoints were pre-bronchodilator forced expiratory volume in 1 s (FEV1) and total asthma symptom score. This study is registered with ClinicalTrials.gov, number NCT01914757. FINDINGS Between Aug 21, 2013, and March 16, 2015, 2505 patients were enrolled, of whom 1306 patients were randomised; 425 patients were randomly assigned to and received benralizumab 30 mg Q4W, 441 to benralizumab 30 mg Q8W, and 440 to placebo. 728 patients were included in the primary analysis population. Benralizumab resulted in significantly lower annual exacerbation rates with the Q4W regimen (rate 0·60 [95% CI 0·48-0·74], rate ratio 0·64 [95% CI 0·49-0·85], p=0·0018, n=241) and Q8W regimen (rate 0·66 [95% CI 0·54-0·82], rate ratio 0·72 [95% CI 0·54-0·95], p=0·0188, n=239) compared with placebo (rate 0·93 [95% CI 0·77-1·12], n=248). Benralizumab also significantly improved pre-bronchodilator FEV1 (Q4W and Q8W) and total asthma symptom score (Q8W only) in these patients. The most common adverse events were nasopharyngitis (90 [21%] in the Q4W group, 79 [18%] in the Q8W group, and 92 [21%] in the placebo group) and worsening asthma (61 [14%] in the Q4W group, 47 [11%] in the Q8W group, and 68 [15%] in the group). INTERPRETATION Benralizumab significantly reduced annual exacerbation rates and was generally well tolerated for patients with severe, uncontrolled asthma with blood eosinophils 300 cells per μL or greater. Our data further refine the patient population likely to receive the greatest benefit from benralizumab treatment. FUNDING AstraZeneca and Kyowa Hakko Kirin.

Abstract
BACKGROUND Eosinophilia is associated with worsening asthma severity and decreased lung function, with increased exacerbation frequency. We assessed the safety and efficacy of benralizumab, a monoclonal antibody against interleukin-5 receptor α that depletes eosinophils by antibody-dependent cell-mediated cytotoxicity, for patients with severe, uncontrolled asthma with eosinophilia. METHODS We did a randomised, double-blind, parallel-group, placebo-controlled phase 3 study at 374 sites in 17 countries. We recruited patients (aged 12-75 years) with a physician-based diagnosis of asthma for at least 1 year and at least two exacerbations while on high-dosage inhaled corticosteroids and long-acting β2-agonists (ICS plus LABA) in the previous year. Patients were randomly assigned (1:1:1) by an interactive web-based voice response system to benralizumab 30 mg either every 4 weeks (Q4W) or every 8 weeks (Q8W; first three doses every 4 weeks) or placebo Q4W for 48 weeks as add on to their standard treatment. Patients were stratified 2:1 according to blood eosinophil counts of at least 300 cells per μL and less than 300 cells per μL. All patients and investigators involved in patient treatment or clinical assessment were masked to treatment allocation. The primary endpoint was annual exacerbation rate ratio versus placebo, and key secondary endpoints were prebronchodilator forced expiratory volume in 1 s (FEV1) and total asthma symptom score at week 48, for patients with blood eosinophil counts of at least 300 cells per μL. Efficacy analyses were by intention to treat (based on the full analysis set); safety analyses included patients according to study drug received. This study is registered with ClinicalTrials.gov, number NCT01928771. FINDINGS Between Sept 19, 2013, and March 16, 2015, 2681 patients were enrolled, 1205 of whom met the study criteria and were randomly assigned: 407 to placebo, 400 to benralizumab 30 mg Q4W, and 398 to benralizumab 30 mg Q8W. 267 patients in the placebo group, 275 in the benralizumab 30 mg Q4W group, and 267 in the benralizumab 30 mg Q8W group had blood eosinophil counts at least 300 cells per μL and were included in the primary analysis population. Compared with placebo, benralizumab reduced the annual asthma exacerbation rate over 48 weeks when given Q4W (rate ratio 0·55, 95% CI 0·42-0·71; p<0·0001) or Q8W (0·49, 0·37-0·64; p<0·0001). Both benralizumab dosing regimens significantly improved prebronchodilator FEV1 in patients at week 48 compared with placebo (least-squares mean change from baseline: Q4W group 0·106 L, 95% CI 0·016-0·196; Q8W group 0·159 L, 0·068-0·249). Compared with placebo, asthma symptoms were improved by the Q8W regimen (least-squares mean difference -0·25, 95% CI -0·45 to -0·06), but not the Q4W regimen (-0·08, -0·27 to 0·12). The most common adverse events were worsening asthma (105 [13%] of 797 benralizumab-treated patients vs 78 [19%] of 407 placebo-treated patients) and nasopharyngitis (93 [12%] vs 47 [12%]). INTERPRETATION These results confirm the efficacy and safety of benralizumab for patients with severe asthma and elevated eosinophils, which are uncontrolled by high-dosage ICS plus LABA, and provide support for benralizumab to be an additional option to treat this disease in this patient population.

Abstract
INTRODUCTION Respiratory allergic disorders like rhinitis and asthma are common conditions that not only affect target organs, but complicate the daily life of affected children and adolescents. OBJECTIVES The aim of this study was to investigate the QoL (quality of life) in children with grass pollen allergy in and out of grass pollen season. METHODS We used the Pediatric Allergic Disease Quality of Life Questionnaire (PADQLQ), a disease-specific questionnaire including both asthma and rhinitis symptoms. We also used the DISABKIDS (a European project which aims at enhancing the quality of life and the independence of children with chronic health conditions and their families) questionnaire, a generic questionnaire covering non-organ-specific effects of disease. RESULTS Ninety-eight children 7–18 years old with grass pollen allergy were included. Eighty-nine children (91%) completed the study. The QoL was significantly decreased during pollen season assessed both with DISABKIDS and PADQLQ. The correlation between the questionnaires was 0.73. Not only the physical domain score (P = 0.00093) but also the emotional domain score (P = 0.034) was significantly lowered. Children with multiple manifestations (asthma and rhinitis) had lower QoL than children with rhinitis alone (P = 0.01). Multiple regression analysis showed a highly significant impact on QoL for symptoms from nose, eyes and lungs. They were equally important (standardized coefficient 047, 0.47 and 0.46, respectively). CONCLUSION The QoL in children and adolescents with respiratory allergy deteriorates during pollen season. This was shown both with generic (DISABKIDS) and disease-specific instrument (PADQLQ).

Abstract
RATIONALE Effective antiinflammatory therapies are needed for the treatment of asthma, but preferably without the systemic adverse effects of glucocorticosteroids. OBJECTIVES We evaluated the effect of an inhaled nonsteroidal glucocorticoid receptor agonist, AZD5423, on allergen-induced responses. METHODS Twenty subjects with mild allergic asthma were randomized to receive 7 days of treatment with nebulized AZD5423 (75 or 300 μg) once daily, budesonide 200 μg twice daily via Turbuhaler, or placebo in a double-blind, four-period, crossover design study. Allergen challenge was performed on Day 6. MEASUREMENTS AND MAIN RESULTS FEV1 was measured repeatedly for 7 hours after allergen challenge for early and late asthmatic responses. Sputum inflammatory cells was measured before and at 7 and 24 hours after allergen challenge, and methacholine airway responsiveness was measured before and 24 hours after allergen challenge. AZD5423 significantly attenuated the fall in FEV1 during the late asthmatic response (both doses led to an 8.7% fall) versus placebo (14% fall) (P < 0.05) with no effect of budesonide (12.5% fall) versus placebo (P > 0.05). There was no effect on the fall in FEV1 during early asthmatic response. AZD5423 300 and 75 μg significantly attenuated allergen-induced sputum eosinophilia by 63 and 61% at 7 hours, respectively, and by 46 and 34% at 24 hours after allergen challenge, respectively, versus placebo (all P < 0.05). Budesonide did not reduce allergen-induced sputum eosinophilia versus placebo. AZD5423 at 300 μg significantly attenuated allergen-induced airway hyperresponsiveness at 24 hours after allergen challenge versus placebo (P < 0.05). Both doses of AZD5423 were well tolerated. CONCLUSIONS Seven-day treatment with inhalation of the nonsteroidal glucocorticoid receptor agonist AZD5423 effectively reduced allergen-induced responses in subjects with mild allergic asthma. Clinical trial registered with www.clinicaltrials.gov (NCT01225549).

Abstract
AIM The aim of the study was to translate and validate the PADQLQ (Pediatric Allergic Disease Quality of Life Questionnaire), a disease-specific quality of life questionnaire for the assessment of quality of life in children with pollen allergy. METHODS The PADQLQ was translated into Swedish according to guidelines. Children aged 7-18 with grass pollen allergy were included. Quality of life was assessed in parallel with ordinary symptom scales (VAS) before, during and after the pollen season. RESULTS A total of 98 children were included and 89 (91%) completed the study. The results for PADQLQ showed good cross-sectional and longitudinal validity. The retrospective estimation after the season showed good consensus with the assessment during pollen season. CONCLUSION Quality of life in children assessed with the PADQLQ (Pediatric Allergic Disease Quality of Life Questionnaire) is a reliable strategy for evaluating the burden of disease in children with pollen allergy and for the evaluation of treatment.

Abstract
AIM Respiratory syncytial virus (RSV) is a prominent cause of airway morbidity in children under 1 y of age. It is assumed that host factors influence the severity of disease presentation, and thus the need for hospitalization. The variation of IGHG genes from chromosome 14q32 are linked to serum IgG subclass levels but also to the variations in IgG responses to pneumococcal, meningococcal and Haemophilus influenzae antigens. The aim of this investigation was to clarify whether IGHG genes are involved in the development of severe RSV lower respiratory tract infection (LRTI). METHODS The alternative expressions of IGHG3(b) and (g), IGHG1(f) and (a), and IGHG2(n) and (-n) genes were studied in a cohort of 49 previously healthy children hospitalized for RSV LRTI. The gene frequencies were compared to a population of healthy individuals. RESULTS The homozygous IGHG2(-n/-n) genotypes dominated in hospitalized children with severe RSV infection: 55.1%, compared with 34.2% in the healthy population (OR 2.3; p = 0.004). The IGHG2 genotypes containing (n/n) and (n/-n) were significantly decreased. The IGHG(bf-n) alleles were significantly increased (OR 1.7; p = 0.025) and the IGHG(bfn) alleles significantly decreased (OR 0.5; p = 0.005). CONCLUSION The IGHG(bf-n) allele and homozygous IGHG2(-n/-n) genotypes are associated with the development of severe RSV LRTI.

Abstract
UNLABELLED A 6-y-old boy presented with a mild, and apparently non-progressive, congenital myopathy, primarily affecting explosive movements such as running and jumping. Five other cases, spanning four generations, were identified in his family. A dominant inheritance pattern was suggested. Quadriceps muscle histology showed a selective type II fibre atrophy, which is otherwise considered a non-specific change associated with a number of conditions. CONCLUSION A Norwegian boy with an inherited muscle weakness is presented. Based on clinical and laboratory investigations, and in light of the inheritance pattern, a previously undescribed congenital myopathy is suggested.

Abstract
Gm allotypes are genetic variants of the immunoglobulin heavy G chains (IGHG) of IgG molecules, coded from chromosome 14q32, characterized by differences in amino acid epitopes of the constant heavy G chains and inherited in the Mendelian manner. Gm allotypes have influence on IgG subclass levels, and serum Gm allotype levels have been given for different Gm genotypes in adults. Four hundred and thirty healthy children, aged 1-15 years, were examined for serum Gm allotypes and IgG subclasses from the six most common Gm genotypes and different age groups were measured using competitive enzyme-linked immunosorbant assay and radial immunodiffusion methods. Quantities (in g/l) of G1m(a) and G1m(f) of IgG1, G2m(n) and G2m(-n) of IgG2 and G3m(g), and G3m(b) of IgG3 are given. Different maturation rates of the alternative Gm allotypes within IgG1, IgG2 and IgG3 were shown. G2m(n) development was strikingly retarded compared with G2m(-n) from the gamma2 locus. This was found comparing IgG2 levels from homozygous G2m(-n-n) and G2m(nn) individuals, but was also seen in heterozygous G2m(n-n) genotypes. From the gamma1 locus G1m(f) levels dominated significantly, but inconstantly, over G1m(a) levels in heterozygous G1m(af) individuals. In homozygous G1m genotypes, G1m(aa) compared with G1m(ff) of the same age, one or the other dominated, sometimes significantly. Serum levels of G3m(b) from the gamma3 locus of homozygous G3m(bb) individuals were increased significantly compared with G3m(g) levels of homozygous G3m(gg) individuals, in ages over 3 years. However, in heterozygous G3m(gb) individuals G3m(b) dominance was not evident. There is a relatively rapid development of G1m(f) molecules and a retarded development of G2m(n) in the Gm(f;n;b) haplotype. In comparison, G1m(a) is retarded and G2m(-n) is enhanced in the Gm(a;-n;g) haplotype. The retarded serum G2m(n) development is comparable with serum IgA development during childhood. Different maturation rates of Gm allotypes within the same IgG subclass provide further explanation for the variation of the antibody response during childhood. Quantitative Gm allotype determinations give information of the activity from IGHG genes. The genetic variation constitutes an additional basis for evaluation of IgG antibodies in different diseases in childhood.

Abstract
Most genetic studies of bronchial asthma deal with IgE responsiveness. The manner by which allergens trigger IgE production and activate mast cells suggests that several genetic loci may be involved. Several reports of candidate genes include chromosome 6 and HLA antigens, chromosome 14q11 and the alpha chain of the T cell receptor, chromosome 11q32 and the beta chain of the high-affinity IgE receptor and chromosome 5 and the gene cluster for IL-4, respectively. In addition, the immunoglobulin heavy chain G (IGHG) genes on chromosome 14q32 have been associated with both atopic and non atopic bronchial asthma in children. In order to further investigate the role of IGHG genes in asthmatic children, the phenotypes of patients with homozygous but alternative IGHG genes were investigated. IGHG gene expression of patients with childhood asthma was determined by serum Gm allotypes with a quantitative competitive indirect ELISA method. The groups consisted of 24 children with the homozygous G3m(b/b)-G1m(f/f)-G2m(n/n) and 16 with the alternative G3m(g/g)-G1m(a/a)-G2m(-n/-n) genes. The two different genotypes were investigated for serum IgE (PRIST), serum IgG subclass levels (radial immunodiffusion), Gm allotype levels (competitive ELISA), IgA and IgM levels (radial immunodiffusion), peripheral blood eosinophils, specific IgE antibodies (skin prick test, SPT, or radioallergosorbent test, RAST), number of peripheral blood CD lymphocyte markers (flow cytometry) and serum IL-4 and IFN-gamma levels (ELISA). Comparison of the two genotypes in children with bronchial asthma revealed significantly increased IgE (p < 0.001), increased specific IgE (p < 0.001), as investigated by SPT or RAST (n = 10 allergens tested), increased number of peripheral blood eosinophils (p < 0.01), increased serum IgG1(f/f)(p < 0.001), IgG2(n/n) (p < 0.001) and IgG3(b/b)(p < 0.01) levels, and decreased CD8 given in percent of the total number of peripheral lymphocytes, (p < 0.02) in the G3m(b/b)-G1m(f/f)-G2m(n/n) genotype. The asthmatic children with the G3m(g/g)-G1m(a/a)-G2m(-n/-n) genes instead showed low IgE levels, practically no specific IgE antibodies, a lower number of peripheral blood eosinophils, lower IgG1(a/a), IgG2(-n/-n) and IgG3(g/g) serum levels and higher CD8 lymphocyte numbers. The results show that the IGHG3(b/b)-IGHG1(f/f)-IGHG2(n/n) genes are in linkage disequilibrium with allergen-specific high-responding IGHE genes and present the atopic phenotype of bronchial asthma, while the IGHG3(g/g)-IGHG1(a/a)-IGHG2(-n/-n) genes present the nonatopic phenotype of childhood asthma. The two genotypes with different amino acid epitopes of their constant heavy gamma1, gamma2 and gamma3 chains presented qualitatively different IgG1, IgG2 and IgG3 molecules, respectively, and also different serum IgG1, IgG2 and IgG3 levels, together with different numbers of peripheral blood eosinophils and CD8 lymphocytes. The two IGHG genotypes represent different pathways of human immune regulation. An association of atopic IGHG genotype with other candidate genes for atopy could be suggested.

Abstract
Peptide growth factors have been reported to contribute to the atherogenic process, and they are known to mediate signals for vascular remodeling. Using syngeneic and allogeneic rat aorta transplant models, we analyzed the impact of cold ischemia time up to 24 hours and reperfusion injury on development of transplant arteriosclerosis during the first 2 months after transplantation. The expression of the transforming growth factor-beta (TGF-beta) family as well as the platelet-derived growth factor (PDGF) and its receptors was studied by use of immunohistochemistry, followed by semiquantitative evaluation and multivariate analysis. In the syngeneically transplanted aortas, the expression of TGF-beta 1, PDGF, and the two PDGF receptors in the neointima increased significantly with the extent of cold ischemia time. Furthermore, there was a significant induction of the latent TGF-beta binding protein in the neointima as well as TGF-beta 2 in the media, both correlating with the observation time after transplantation. In the allogeneic grafts, all examined proteins were already induced strongly 2 weeks after transplantation, even at the shortest ischemic period studied (1 hour). However, no positive correlation between growth factor expression and cold ischemia or observation time could be found. Double immunohistochemistry revealed that macrophages express PDGF and its receptors as well as TGF-beta 1. Smooth muscle cells express both types of PDGF receptors, and a few T cells express TGF-beta 1 as well as PDGF receptors. In summary, TGF-beta and PDGF are induced by allogeneic as well as ischemic stimuli in transplanted aortas, suggesting a role in the pathogenesis of transplant arteriosclerosis and representing a potential target for therapeutic intervention.

Abstract
The influence of the somatostatin analogue angiopeptin on transplant arteriosclerosis was investigated using two aortic transplantation rat models. One was characterized by ischemia/reperfusion-induced changes in syngeneic transplants while immunologically induced changes dominated in the other allogeneic model. Angiopeptin, 100 micrograms/kg per day, was administered continuously until the sacrifice of the rats after 8 weeks. No additional immunosuppression was used in either model. An image analysis system was used to quantify the intimal and medial thicknesses of the grafts. In the syngeneic grafts, the intimal thickness was less than 50% of that of control grafts (P < 0.05), but no difference was seen in the allogeneic model. The expression of selected cells, TGF-beta s, and PDGF and PDGF alpha-receptors was detected immunohistochemically and displayed a similar picture in control and angiopeptin-treated grafts in both models. We conclude that angiopeptin has no clear immunosuppressive properties but may counteract ischemia-induced transplant arteriosclerosis.

Abstract
C-CAM (Cell-CAM 105) is a transmembrane cell adhesion molecule belonging to the immunoglobulin superfamily. It mediates intercellular adhesion of rat hepatocytes and occurs in various isoforms in several epithelia, vessel endothelia and leukocytes. We now report that purified liver C-CAM interacts specifically with calmodulin. Binding was observed both when 125I-labeled C-CAM was used in a dot-blot assay and when 125I-labeled calmodulin was used in a gel overlay assay. Experiments with protease-generated peptides indicated that calmodulin bound to the cytoplasmic domain of C-CAM. Analyses of whole liver membranes demonstrated that C-CAM is one of five major proteins that bind calmodulin in a calcium-dependent manner.

Abstract
Cell-CAM 105 (C-CAM), a cell adhesion molecule in rat hepatocytes, was digested with trypsin, and peptides were isolated and sequenced by Edman degradation. The sequences of 4 peptides agreed with different regions of rat liver ecto-ATPase. Detailed biochemical analyses confirmed the identity between C-CAM and the ecto-ATPase. C-CAM/ecto-ATPase is a transmembrane protein having 4 immunoglobulin-like domains in the extracellular portion, demonstrating membership of the immunoglobulin superfamily. The ATPase activity suggests that ATP might influence cell adhesion, which would explain the inhibitory effect of exogenously added ATP on adhesion of several cell types.

Abstract
C-CAM (Cell-CAM 105) is a cell surface glycoprotein that is involved in cell-cell adhesion of rat hepatocytes in vitro. To elucidate the adhesion mechanism the binding properties of purified C-CAM were investigated. Using proteins immobilized on nitrocellulose it was found that radiolabeled C-CAM bound to C-CAM but not to a variety of other proteins. Partitioning in Triton X-114 showed that C-CAM has hydrophobic properties. In accordance with this, C-CAM was effectively incorporated into phosphatidylcholine liposomes by dialysis from octylglucoside-containing solutions. The C-CAM-containing liposomes bound specifically to isolated hepatocytes. This binding was blocked by Fab fragments of anti-C-CAM antibodies. Furthermore, preincubation of hepatocytes with anti-C-CAM antibodies followed by washing of the cells blocked binding of C-CAM-containing liposomes. At increasing C-CAM contents in the reconstituted liposomes a marked self-aggregation of the liposomes occurred. This aggregation was blocked by Fab fragments of anti-C-CAM antibodies and by alkaline pH. After neutralization a rapid reaggregation occurred. Neither C-CAM binding to C-CAM immobilized on nitrocellulose nor C-CAM-liposome aggregation required calcium ions. Liposomes reconstituted with C-CAM-depleted membrane glycoproteins did not self-aggregate or bind to hepatocytes. Thus, it is concluded that C-CAM can bind specifically to C-CAM in a homophilic binding reaction that does not require calcium. Accordingly, C-CAM has the potential of directly mediating cell-cell adhesion via C-CAM-C-CAM binding between adjacent cells.
