Summary The FORWARD study is a randomised, double-blind trial that compares the efficacy and safety of 48 weeks treatment with extrafine beclomethasone dipropionate/formoterol fumarate (BDP/FOR), ...100/6 μg pMDI, 2 inhalations BID, vs. FOR 12 μg pMDI, 1 inhalation BID, in severe COPD patients with a history of exacerbations. Co-primary endpoints were exacerbation rate over 48 weeks and pre-dose morning FEV1 at 12 weeks. The ITT population included 1186 patients (69% males, mean age 64 years) with severe airflow limitation (mean post-bronchodilator FEV1 42% predicted). Salbutamol as rescue therapy, theophylline and tiotropium (if stable regimen prior to screening) were allowed. Compared to FOR, BDP/FOR: (1) reduced the exacerbation rate (rate ratio: 0.72 95% confidence interval 0.62–0.84, p < 0.001); (2) improved pre-dose morning FEV1 (mean difference: 0.069 L 0.043–0.095 p < 0.001); (3) prolonged the time to first exacerbation; (4) improved the SGRQ total score. The percentage of patients with adverse events was similar (52.1% with BDP/FOR and 49.2% with FOR). Pneumonia incidence was low, slightly higher with BDP/FOR (3.8%) than with FOR (1.8%). No difference for laboratory values, ECG or vital signs. Extrafine BDP/FOR significantly reduces the exacerbation rate and improves lung function of patients with severe COPD and history of exacerbations as compared to FOR alone.
Summary Omalizumab is a humanized murine monoclonal antibody directed toward a portion of the IgE indicated in Europe for the treatment of severe persistent allergic asthma, inadequately controlled ...despite high-dose of ICS (mean BDP equivalent dose of inhaled corticosteroid 2224.68 μg/die) in association with long-acting β2 agonists. Our aim was to describe the experience, efficacy and safety in a cohort of Italian patients treated with omalizumab in a real-life clinical setting. One hundred and forty two patients from 13 Italian Centers were observed and analysed. The dosage of omalizumab was established according to the labelling indication, with a median dose of IgE of 297.38 IU/ml or kU/l. During the previous year, all patients experienced frequent exacerbations (mean = 4.87), emergency visits (mean = 4.45) and hospitalisation (mean = 1.53). Following treatment with omalizumab, the annual rate of exacerbations, emergency visits and hospitalisation decreased by 79%, 88% and 95%, respectively. The proportion of patients without exacerbation, not needing emergency visits and hospitalization increased by 610%, 154% and 28%, respectively. The response to omalizumab measured with the GETE (global evaluation of treatment effectiveness) scale rated as good to excellent in 77% of patients. Overall, 9.6% ( n = 9) of the patients experienced one single adverse effect. Only one patient reported a serious adverse event (local reaction at the site of injection) leading to interruption of treatment. The observed reduction of asthma-related events in particularly poorly controlled patients in this Italian real-life setting is consistent with the results of other observational studies.
Background. Oxidative stress plays a role in the pathogenesis of many chronic inflammatory lung diseases. Exhaled breath condensate (EBC) collection is a noninvasive method to investigate pulmonary ...oxidative stress biomarkers such as malondialdehyde (MDA). Subjects and Methods. We measured MDA levels in EBC in a large number of patients (N=194) with respiratory diseases: asthma (N=64), bronchiectasis (BE, N=19), chronic obstructive pulmonary disease (COPD, N=73), idiopathic pulmonary fibrosis (IPF, N=38). Fourteen healthy nonsmoking subjects were included as controls. Results. Excluding IPF subjects, MDA levels were significantly higher in all disease groups than in control group. MDA was significantly higher in COPD than asthmatic and BE subjects. Among asthmatics, corticosteroids-treated subjects had lower MDA levels than untreated subjects. COPD subjects showed an inverse correlation between MDA concentrations and FEV1% (rho: −0.24, P<.05). Conclusions. EBC-MDA is increased in subjects with chronic airway disorders, particularly in COPD, and it is related to FEV1 reduction.
Abstract Background This retrospective study aimed at evaluating long-term effects of Omalizumab in elderly asthmatics in a real-life setting. Methods 105 consecutive severe asthmatics (GINA step ...4–5; mean FEV1 % predicted:66 ± 15.7) treated with Omalizumab for at least 1 year (treatment mean duration 35.1 ± 21.7 months) were divided into 3 groups according to their age at Omalizumab treatment onset: 18–39, 40–64 and ≥ 65 years. Results Comorbidities, number of overweight/obese subjects and patients with late-onset asthma were more frequent among older people. A similar reduction of inhaled corticosteroids dosage and SABA on-demand therapy was observed in all groups during Omalizumab treatment; a similar FEV1 increased was also observed. Asthma Control Test (ACT) improved significantly (p < 0.001) in the three groups, increasing from 15 IQR:12-18 to 24 IQR:22-25 in younger subjects, from 14 IQR:10-16 to 21 IQR:20-23 in the 40-64-year-group and from 15 IQR:12-16 to 20 IQR:18-22 in elderly patients where improvement was lower (p = 0.039) compared to younger people. Asthma exacerbation decreased significantly after Omalizumab but the percentage of exacerbation-free patients was higher in younger people (76.9%) compared to middle aged patients (49.2%) and the elderly (29%) (p = 0.049). After Omalizumab treatment, the risk for exacerbations was lower in subjects aged 40–64 (OR = 0.284 CI95% = 0.098–0.826, p = 0.021) and 18–39 (OR = 0.133 CI95% = 0.026–0.678, p = 0.015), compared to elderly asthmatics. Also, a significantly reduced ACT improvement (β = −1.070; p = 0.046) passing from each age class was observed. Conclusion Omalizumab improves all asthma outcomes independently of age, although the magnitude of the effects observed in the elderly seems to be lower than in the other age groups.
Despite adding Omalizumab to conventional therapy, several severe asthmatics still show poor disease control. We investigated the factors that may affect a reduced Omalizumab response in a large ...population of severe asthmatics.
340 patients were retrospectively evaluated. FEV1%, FVC%, Asthma Control Test (ACT), fractional exhaled nitric oxide (FENO), possible step-downs/step-ups of concomitant therapies, exacerbations, disease control levels, ICS doses and SABA use, observed at the end of treatment, were considered as a response to Omalizumab.
Age was an independent risk factor for a reduced response concerning FEV1%, FVC%, ACT and for a lower asthma control. Obesity (vs normal weight) was a determinant condition for exacerbations (OR:3.1141.509–6.424, p = 0.002), for a disease partial/no control (OR:2.6651.064–6.680, p = 0.036), for excessive SABA use (OR:4.4481.837–10.768, p = 0.002) and for an unchanged/increased level of concomitant asthma medications. Furthermore, obesity also reduced the response in FEV1 (β = −6.981,p = 0.04), FVC (β = −11.689,p = 0.014) and ACT (β = −2.585, p = 0.027) and was associated with a higher FENO level (β = 49.045,p = 0.040). Having at least one comorbidity was a risk factor for exacerbations (OR:1.3831.128–1.697, p = 0.008) and for an ACT <20 (OR:2.4101.071–3.690, p = 0.008). Specifically, chronic heart disease was associated with both a lower ACT and FVC% whereas gastroesophageal reflux with a partial/no asthma control. Nasal polyps were a predisposing factor leading both to exacerbations and to the use of higher inhaled corticosteroids doses. Moreover, smoking habits, pollen or dog/cat dander co-sensitizations may negatively influence Omalizumab response.
Age, obesity, comorbidities, smoking habits, nasal polyps, allergic poly-sensitization might reduce Omalizumab effectiveness independently to other asthma-influencing factors.
•A fair proportion of severe asthmatics may have a reduced Omalizumab response.•Several factors may reduce Omalizumab effectiveness in these patients.•They are: age, obesity, comorbidities, smoking, nasal polyps, polysensitization.•These factors act independently of many asthma-influencing variables.•When managing these patients, we should consider multidisciplinary interventions.
Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) generally have a high symptom burden and poor health-related quality of life, often requiring recurring systemic corticosteroid use and ...repeated sinus surgery. Dupilumab is a fully human monoclonal antibody that inhibits signalling of interleukin (IL)-4 and IL-13, key drivers of type 2 inflammation, and has been approved for use in atopic dermatitis and asthma. In these two studies, we aimed to assess efficacy and safety of dupilumab in patients with CRSwNP despite previous treatment with systemic corticosteroids, surgery, or both.
LIBERTY NP SINUS-24 and LIBERTY NP SINUS-52 were two multinational, multicentre, randomised, double-blind, placebo-controlled, parallel-group studies assessing dupilumab added to standard of care in adults with severe CRSwNP. SINUS-24 was done in 67 centres in 13 countries, and SINUS-52 was done in 117 centres in 14 countries. Eligible patients were 18 years or older with bilateral CRSwNP and symptoms despite intranasal corticosteroid use, receiving systemic corticosteroids in the preceding 2 years, or having had sinonasal surgery. Patients in SINUS-24 were randomly assigned (1:1) to subcutaneous dupilumab 300 mg or placebo every 2 weeks for 24 weeks. Patients in SINUS-52 were randomly assigned (1:1:1) to dupilumab 300 mg every 2 weeks for 52 weeks, dupilumab every 2 weeks for 24 weeks and then every 4 weeks for the remaining 28 weeks, or placebo every 2 weeks for 52 weeks. All patients were randomly assigned centrally with a permuted block randomisation schedule. Randomisation was stratified by asthma or non-steroidal anti-inflammatory drug-exacerbated respiratory disease status at screening, previous surgery at screening, and country. Patients with or without comorbid asthma were included. Coprimary endpoints were changes from baseline to week 24 in nasal polyp score (NPS), nasal congestion or obstruction, and sinus Lund-Mackay CT scores (a coprimary endpoint in Japan), done in an intention-to-treat population. Safety was assessed in a pooled population of both dupilumab groups in SINUS-52 up to week 24 and the dupilumab group in SINUS-24 and the placebo groups in both studies until week 24. The trials are complete and registered at ClinicalTrials.gov, NCT02912468 and NCT02898454.
Between Dec 5, 2016, and Aug 3, 2017, 276 patients were enrolled in SINUS-24, with 143 in the dupilumab group and 133 in the placebo group receiving at least one study drug dose. Between Nov 28, 2016, and Aug 28, 2017, 448 patients were enrolled in SINUS-52, with 150 receiving at least one dose of dupilumab every 2 weeks, 145 receiving at least one dose of dupilumab every 2 weeks for 24 weeks and every 4 weeks until week 52, and 153 receiving at least one dose of placebo. Dupilumab significantly improved the coprimary endpoints in both studies. At 24 weeks, least squares mean difference in NPS of dupilumab treatment versus placebo was −2·06 (95% CI −2·43 to −1·69; p<0·0001) in SINUS-24 and −1·80 (−2·10 to −1·51; p<0·0001) in SINUS-52; difference in nasal congestion or obstruction score was −0·89 (−1·07 to −0·71; p<0·0001) in SINUS-24 and −0·87 (−1·03 to −0·71; p<0·0001) in SINUS-52; and difference in Lund-Mackay CT scores was −7·44 (−8·35 to −6·53; p<0·0001) in SINUS-24 and −5·13 (−5·80 to −4·46; p<0·0001) in SINUS-52. The most common adverse events (nasopharyngitis, worsening of nasal polyps and asthma, headache, epistaxis, and injection-site erythema) were more frequent with placebo.
In adult patients with severe CRSwNP, dupilumab reduced polyp size, sinus opacification, and severity of symptoms and was well tolerated. These results support the benefits of adding dupilumab to daily standard of care for patients with severe CRSwNP who otherwise have few therapeutic options.

The choice of inhaler device for asthma patients depends upon multiple attributes. We investigated factors that may drive general practitioners (GPs) and respiratory specialists in the prescription ...of inhaler devices for asthma patients who initiated inhalation therapy.
We retrospectively analysed prescriptions by GPs and respiratory specialists to asthma patients commencing inhaled corticosteroid/long-acting β2-agonist combination therapy available as both pressurised metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs). Patient characteristics were compared by device and multivariate analysis was used to model the likelihood of receiving a pMDI as opposed to a DPI in order to identify drivers for prescription. A sample of the respiratory specialists completed an ad-hoc survey of their perceived success in achieving asthma control in their patients and barriers to attaining full control.
Prescription of a particular inhaler device was unrelated to the characteristics of the patients. Multivariate analysis revealed that the main driver for the choice of inhaler device was the medication (Odds Ratio and 95% Confidence Interval, respectively for GPs and specialists: 0.19 0.16–0.23; 0.17 0.08–0.37). Specialists perceived asthma as being inadequately controlled in 41% of their patients, and considered patients' difficulties in using DPIs and pMDIs as instrumental in this, citing a need for a novel, more effective inhaler technology.
Physicians choose inhaler devices according to the prescribed drugs and not to the characteristics of the individual patient. This may reflect a lack of confidence in existing inhaler devices and underlines the need for technologies, which are more reliable and easier to use by patients.
•Inhaler choice is as critical as the choice of the medication itself.•Prescribers should select the inhaler based on the patient's characteristics and needs.•Prescription of a particular inhaler device is unrelated to the characteristics of the patients.•The strongest driver of inhaler choice is the medication.
The present study was designed to compare the fixed combination of beclomethasone and formoterol in a hydrofluoroalkane Modulite (Chiesi Farmaceutici, Parma, Italy) pressurised metered-dose inhaler ...(pMDI), with a combination of budesonide and formoterol administered via a Turbuhaler (AstraZeneca, Lund, Sweden) dry powder inhaler (DPI). This was a phase III, multinational, multicentre, double-blind, double-dummy, randomised, two-arm parallel groups, controlled study design. After a 2-week run-in period, 219 patients with moderate-to-severe asthma were randomised to a 12-week treatment with beclomethasone 200 microg plus formoterol 12 microg b.i.d. delivered via a pMDI or budesonide 400 microg plus formoterol 12 microg b.i.d. delivered via a DPI. The analysis of noninferiority on primary outcome, morning peak expiratory flow in the last 2 weeks of treatment, showed no difference between groups. A statistically significant improvement from baseline in lung function, symptoms and rescue medication use was observed in both groups at all time-points. No differences were observed between treatments in either rate of asthma exacerbations or frequency of adverse events. The new fixed combination of beclomethasone and formoterol in hydrofluoroalkane Modulite pressurised metered-dose inhaler is equivalent to the marketed combination of budesonide and formoterol in terms of efficacy and tolerability profile.
Summary Introduction At variance from office spirometry, telespirometry has not been tested as a tool for improving the ability of general practitioners (GPs) to manage chronic airway diseases. ...Methods After adequate training, 937 Italian GPs agreed to perform telespirometry in subjects attending their clinics who had risk factors, persistent respiratory symptoms, or a previous diagnosis of asthma or COPD. Each subject performed at least three forced expiratory manoeuvres using a turbine spirometer. Traces were sent by telephone to a Telespirometry Central Office, where they were interpreted by a pulmonary specialist, according to defined criteria. The result was sent in real time to the GP to assist the management of the patient. Results During 2 years, 20,757 telespirometries were performed, with a mean of 22.2 ± 25.2 examinations for each GP. 70% of the tests met the criteria for good or partial co-operation, allowing spirometric abnormalities to be detected in more than 40% of the tracings. The rate of telespirometries that could not be evaluated at all was reasonably low (9.2%). For a subset of the telespirometries, a comparison between acceptability criteria for telespirometry and those recommended for laboratory (ATS) or office spirometry showed that the majority of telespirometries with good co-operation satisfied completely, or with minor deviations, the ATS and Office criteria. Conclusions Telespirometry was well accepted by Italian GPs, who obtained acceptable screening traces in a large percentage of subjects. Therefore it might be considered a useful alternative to office spirometry in improving the management of chronic airway diseases by GPs.
Even if severe asthma (SA) accounts for 5-10% of all cases of the disease, it is currently a crucial unmet need, owing its difficult clinical management and its high social costs. For this reason ...several networks, focused on SA have been organized in some countries, in order to select these patients, to recognize their clinical features, to evaluate their adherence, to classify their biological/clinical phenotypes, to identify their eligibility to the new biologic therapies and to quantify the costs of the disease. Aim of the present paper is to describe the ongoing Italian Severe Asthma Network (SANI). Up today 49 centres have been selected, widespread on the national territory. Sharing the same diagnostic protocol, data regarding patients with SA will be collected and processed in a web platform. After their recruitment, SA patients will be followed in the long term in order to investigate the natural history of the disease. Besides clinical data, the cost/benefit evaluation of the new biologics will be verified as well as the search of peculiar biomarker(s) of the disease.
