Efficacy, Safety, and Systemic Exposure of Once-Daily Indacaterol Acetate in Pediatric Asthma: A Randomized, Double-Blind, Controlled Dose-Finding Study. Clin Drug Investig 2023; 43:719-728. [PMID: 37682405 PMCID: PMC10514176 DOI: 10.1007/s40261-023-01300-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/08/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Indacaterol acetate (IND), a long-acting β2-agonist in combination with mometasone furoate (MF), an inhaled corticosteroid (ICS), is being explored as a once-daily (od) treatment for asthma in children. This study examined the efficacy, safety, and systemic exposure of IND 75 µg and IND 150 µg in children with persistent asthma. METHODS In this Phase IIb, multicenter, randomized, double-blind, parallel-group study, pediatric patients (aged ≥ 6 to < 12 years) with persistent asthma were randomized (1:1) to receive either IND 75 µg od or IND 150 µg od via Breezhaler® in combination with ICS background therapy. The primary endpoint was change from baseline in pre-dose trough forced expiratory volume in one second (FEV1) after two weeks of treatment. RESULTS In total, 80 patients received IND 75 µg (n = 39) or IND 150 µg (n = 41). The study met its primary endpoint; both doses demonstrated improvements in pre-dose trough FEV1 from baseline to Day 14 (mean change [Δ]: 212 mL, IND 75 µg; 171 mL, IND 150 µg). The secondary spirometry parameters (post-dose FEV1 after 1-h, post-dose forced vital capacity; morning and evening peak expiratory flow) also improved. Overall, 36.1% in IND 75 μg group and 25% patients in IND 150 μg group achieved a decrease from baseline in Pediatric Interviewer-administered Asthma Control Questionnaire score of ≥ 0.5 units. A dose-dependent increase in plasma IND concentration was noted between the two groups. Both IND doses demonstrated an acceptable safety profile. CONCLUSIONS Once-daily IND 75 μg and IND 150 μg via Breezhaler® in combination with background ICS therapy provided substantial bronchodilation in children with asthma and were well tolerated. Taken together, these clinical and systemic exposure findings support IND 75 μg as the most appropriate dose for evaluation in Phase III trials in combination with MF in pediatric asthma. TRIAL REGISTRATION ClinicalTrials.gov (NCT02892019; 08-Sep-2016).

Quantitative comparison of different inhaled corticosteroids in the treatment of asthma in children. Pediatr Res 2023; 93:31-38. [PMID: 35545660 DOI: 10.1038/s41390-022-02095-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 03/23/2022] [Accepted: 04/09/2022] [Indexed: 01/28/2023]
Abstract
BACKGROUND The GINA recommends inhaled corticosteroids (ICSs) for the treatment of steps 2-3 of childhood asthma. However, the difference in efficacy between these drugs remains unclear. The purpose of this study was to compare the efficacy of different ICS drugs in the treatment of childhood asthma. METHODS We searched PubMed and EMBASE for randomized controlled trials of ICSs in the treatment of childhood asthma. Using forced expiratory volume in the first second (FEV1) as the primary outcome, a time-course model of ICSs was constructed. In addition, the symptom-free days% were analyzed as a secondary outcome. RESULTS Six studies involving 2237 children that reported FEV1 were included. The results showed that the ET50 of ciclesonide (CIC) and budesonide (BUD) was 1.23 and 2.97 weeks, respectively. Compared with them, FP had a higher efficacy. In terms of symptom-free days%, we found that the efficacy of beclometasone dipropionate was lower than that of CIC and fluticasone propionate. CONCLUSION In this study, the efficacy of three ICS drugs was quantitatively compared, providing necessary information for the implementation of medication guidelines for steps 2-3 of asthma in children. IMPACT This study analyzed the entire time-course of the drug efficacy of Inhaled corticosteroids in the treatment of asthma in children aged 5-12, which found that although the maximum efficacy of both ciclesonide and budesonide was the same, the onset speed of ciclesonide was faster than that of budesonide. The above information provides the necessary quantitative information for the implementation of medication guidelines for steps 2-3 asthma in children.

Abstract
Asthma is a disease of the airways that is characterized by chronic inflammation and disordered airway function. The purpose of writing the current review paper is to review the history, current situation, control history, challenges, and ongoing management programs of asthma. Some official websites of known respiratory professional bodies were consulted for asthma guidelines, and information from Google Scholar® and PubMed® was also consulted. We reviewed around two hundred eight papers, and then, inclusion and exclusion criteria were applied to prepare this manuscript. Out of these papers, thirty papers, factsheets, and some official websites were used to prepare this manuscript. Physicians should follow already existing asthma guidelines in order to manage asthma. All prescribed medications should be continued. The government should make and adopt more strategies to promote the rational use of anti-asthmatic drugs and healthcare facilities and also make plans to disseminate more awareness among people about the schemes and programs made for safeguarding people against this life-threatening disease. We have done so much advancement to fight against this deadly disease, and we still need time to make the globe asthma-free. The number of people suffering from asthma is more than the number of people suffering from HIV infection and tuberculosis. Understanding the recommendations of professional bodies will assist in medical decision-making in asthma management. The individual needs of patients should be considered by healthcare professionals. Graphical Abstract

Abstract
Bronchodilators remain the cornerstone of the treatment of airway disorders such as asthma and chronic obstructive pulmonary disease (COPD). There is therefore considerable interest in understanding how to optimize the use of our existing classes of bronchodilator and in identifying novel classes of bronchodilator drugs. However, new classes of bronchodilator have proved challenging to develop because many of these have no better efficacy than existing classes of bronchodilator and often have unacceptable safety profiles. Recent research has shown that optimization of bronchodilation occurs when both arms of the autonomic nervous system are affected through antagonism of muscarinic receptors to reduce the influence of parasympathetic innervation of the lung and through stimulation of β 2-adrenoceptors (β 2-ARs) on airway smooth muscle with β 2-AR-selective agonists to mimic the sympathetic influence on the lung. This is currently achieved by use of fixed-dose combinations of inhaled long-acting β 2-adrenoceptor agonists (LABAs) and long-acting muscarinic acetylcholine receptor antagonists (LAMAs). Due to the distinct mechanisms of action of LAMAs and LABAs, the additive/synergistic effects of using these drug classes together has been extensively investigated. More recently, so-called "triple inhalers" containing fixed-dose combinations of both classes of bronchodilator (dual bronchodilation) and an inhaled corticosteroid in the same inhaler have been developed. Furthermore, a number of so-called "bifunctional drugs" having two different primary pharmacological actions in the same molecule are under development. This review discusses recent advancements in knowledge on bronchodilators and bifunctional drugs for the treatment of asthma and COPD. SIGNIFICANCE STATEMENT: Since our last review in 2012, there has been considerable research to identify novel classes of bronchodilator drugs, to further understand how to optimize the use of the existing classes of bronchodilator, and to better understand the role of bifunctional drugs in the treatment of asthma and chronic obstructive pulmonary disease.

Respir Med 2020; 170:106055. [PMID: 32843176 DOI: 10.1016/j.rmed.2020.106055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 05/26/2020] [Accepted: 05/28/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Pressurised metered dose inhalers (pMDIs) are effective drug delivery devices prescribed in obstructive airway diseases due to their convenience, portability, ease of enabling multiple doses in a single formulation, and storage in any orientation. For the management of asthma, the fixed-dose combination of a long-acting β2-agonist (LABA) and an inhaled corticosteroid (ICS) has been recommended by Global Initiative for Asthma guideline as a preferred treatment option for patients who are uncontrolled with only ICS doses. One of the available LABA/ICS combinations is the formoterol/budesonide (FB). AREAS COVERED This article systematically reviews the efficacy and safety of the FB pMDI compared with the FB dry powder inhaler (DPI), individual mono-components (formoterol and budesonide) or salmeterol/fluticasone (SF) combination in the treatment of asthma among paediatric and adult patients. PubMed was searched with the string: ''((Budesonide) AND Formoterol) AND ((((pMDI) OR MDI) OR Pressurised Metered-dose inhaler) OR Metered-dose inhaler)'', in ALL fields. Screening of all the articles was done till February 2020. We have included 24 articles from the total of 142 hits received. CONCLUSIONS The FB pMDI is efficacious for the long-term management of asthma in patients 6 years of age and above. It has been shown to improve lung function and asthma control, and to reduce daytime and night-time symptoms, the number of rescue medication doses and asthma exacerbations. It also showed rapid onset of bronchodilatory effect with a dose-response relationship that allows patients to utilise it as a Single Maintenance And Reliever Therapy (SMART) regimen.

A comparison of tiotropium, long-acting β 2-agonists and leukotriene receptor antagonists on lung function and exacerbations in paediatric patients with asthma. Respir Res 2020; 21:19.

Abstract
Diagnosing and treating asthma in paediatric patients remains challenging, with many children and adolescents remaining uncontrolled despite treatment. Selecting the most appropriate pharmacological treatment to add onto inhaled corticosteroids (ICS) in children and adolescents with asthma who remain symptomatic despite ICS can be difficult. This literature review compares the efficacy and safety of long-acting β2-agonists (LABAs), leukotriene receptor antagonists (LTRAs) and long-acting muscarinic antagonists (LAMAs) as add-on treatment to ICS in children and adolescents aged 4-17 years.A literature search identified a total of 29 studies that met the inclusion criteria, including 21 randomised controlled trials (RCTs) of LABAs versus placebo, two RCTs of LAMAs (tiotropium) versus placebo, and four RCTs of LTRA (montelukast), all as add-on to ICS. In these studies, tiotropium and LABAs provided greater improvements in lung function than LTRAs, when compared with placebo as add-on to ICS. Although exacerbation data were difficult to interpret, tiotropium reduced the risk of exacerbations requiring oral corticosteroids when added to ICS, with or without additional controllers. LABAs and LTRAs had a comparable risk of asthma exacerbations with placebo when added to ICS. When adverse events (AEs) or serious AEs were analysed, LABAs, montelukast and tiotropium had a comparable safety profile with placebo.In conclusion, this literature review provides an up-to-date overview of the efficacy and safety of LABAs, LTRAs and LAMAs as add-on to ICS in children and adolescents with asthma. Overall, tiotropium and LABAs have similar efficacy, and provide greater improvements in lung function than montelukast as add-on to ICS. All three controller options have comparable safety profiles.

Abstract
BACKGROUND Epidemiological evidence has suggested a link between beta2-agonists and increases in asthma mortality. There has been much debate about whether regular (daily) long-acting beta2-agonists (LABA) are safe when used in combination with inhaled corticosteroids (ICS). This updated Cochrane Review includes results from two large trials that recruited 23,422 adolescents and adults mandated by the US Food and Drug Administration (FDA). OBJECTIVES To assess the risk of mortality and non-fatal serious adverse events (SAEs) in trials that randomly assign participants with chronic asthma to regular formoterol and inhaled corticosteroids versus the same dose of inhaled corticosteroid alone. SEARCH METHODS We identified randomised trials using the Cochrane Airways Group Specialised Register of trials. We checked websites of clinical trial registers for unpublished trial data as well as FDA submissions in relation to formoterol. The date of the most recent search was February 2019. SELECTION CRITERIA We included randomised clinical trials (RCTs) with a parallel design involving adults, children, or both with asthma of any severity who received regular formoterol and ICS (separate or combined) treatment versus the same dose of ICS for at least 12 weeks. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We obtained unpublished data on mortality and SAEs from the sponsors of the studies. We assessed our confidence in the evidence using GRADE recommendations. The primary outcomes were all-cause mortality and all-cause non-fatal serious adverse events. MAIN RESULTS We found 42 studies eligible for inclusion and included 39 studies in the analyses: 29 studies included 35,751 adults, and 10 studies included 4035 children and adolescents. Inhaled corticosteroids included beclomethasone (daily metered dosage 200 to 800 µg), budesonide (200 to 1600 µg), fluticasone (200 to 250 µg), and mometasone (200 to 800 µg). Formoterol metered dosage ranged from 12 to 48 µg daily. Fixed combination ICS was used in most of the studies. We judged the risk of selection bias, performance bias, and attrition bias as low, however most studies did not report independent assessment of causation of SAEs.DeathsSeventeen of 18,645 adults taking formoterol and ICS and 13 of 17,106 adults taking regular ICS died of any cause. The pooled Peto odds ratio (OR) was 1.25 (95% confidence interval (CI) 0.61 to 2.56, moderate-certainty evidence), which equated to one death occurring for every 1000 adults treated with ICS alone for 26 weeks; the corresponding risk amongst adults taking formoterol and ICS was also one death (95% CI 0 to 2 deaths). No deaths were reported in the trials on children and adolescents (4035 participants) (low-certainty evidence).In terms of asthma-related deaths, no children and adolescents died from asthma, but three of 12,777 adults in the formoterol and ICS treatment group died of asthma (both low-certainty evidence).Non-fatal serious adverse eventsA total of 401 adults experienced a non-fatal SAE of any cause on formoterol with ICS, compared to 369 adults who received regular ICS. The pooled Peto OR was 1.00 (95% CI 0.87 to 1.16, high-certainty evidence, 29 studies, 35,751 adults). For every 1000 adults treated with ICS alone for 26 weeks, 22 adults had an SAE; the corresponding risk for those on formoterol and ICS was also 22 adults (95% CI 19 to 25).Thirty of 2491 children and adolescents experienced an SAE of any cause when receiving formoterol with ICS, compared to 13 of 1544 children and adolescents receiving ICS alone. The pooled Peto OR was 1.33 (95% CI 0.71 to 2.49, moderate-certainty evidence, 10 studies, 4035 children and adolescents). For every 1000 children and adolescents treated with ICS alone for 12.5 weeks, 8 had an non-fatal SAE; the corresponding risk amongst those on formoterol and ICS was 11 children and adolescents (95% CI 6 to 21).Asthma-related serious adverse eventsNinety adults experienced an asthma-related non-fatal SAE with formoterol and ICS, compared to 102 with ICS alone. The pooled Peto OR was 0.86 (95% CI 0.64 to 1.14, moderate-certainty evidence, 28 studies, 35,158 adults). For every 1000 adults treated with ICS alone for 26 weeks, 6 adults had an asthma-related non-fatal SAE; the corresponding risk for those on formoterol and ICS was 5 adults (95% CI 4 to 7).Amongst children and adolescents, 9 experienced an asthma-related non-fatal SAE with formoterol and ICS, compared to 5 on ICS alone. The pooled Peto OR was 1.18 (95% CI 0.40 to 3.51, very low-certainty evidence, 10 studies, 4035 children and adolescents). For every 1000 children and adolescents treated with ICS alone for 12.5 weeks, 3 had an asthma-related non-fatal SAE; the corresponding risk on formoterol and ICS was 4 (95% CI 1 to 11). AUTHORS' CONCLUSIONS We did not find a difference in the risk of death (all-cause or asthma-related) in adults taking combined formoterol and ICS versus ICS alone (moderate- to low-certainty evidence). No deaths were reported in children and adolescents. The risk of dying when taking either treatment was very low, but we cannot be certain if there is a difference in mortality when taking additional formoterol to ICS (low-certainty evidence).We did not find a difference in the risk of non-fatal SAEs of any cause in adults (high-certainty evidence). A previous version of the review had shown a lower risk of asthma-related SAEs in adults taking combined formoterol and ICS; however, inclusion of new studies no longer shows a difference between treatments (moderate-certainty evidence).The reported number of children and adolescents with SAEs was small, so uncertainty remains in this age group.We included results from large studies mandated by the FDA. Clinical decisions and information provided to patients regarding regular use of formoterol and ICS need to take into account the balance between known symptomatic benefits of formoterol and ICS versus the remaining degree of uncertainty associated with its potential harmful effects.

Abstract
OBJECTIVE Although many children with asthma do not experience persistence into adulthood, recent studies have suggested that poorly controlled asthma in childhood may be associated with significant airflow obstruction in adulthood. However, data regarding disease progression are lacking, and clinicians are not yet able to predict the course of a child's asthma. The goal of this article was to assess the current understanding of childhood asthma treatment and progression and to highlight gaps in information that remain. DATA SOURCES Nonsystematic PubMed literature search and authors' expertise. STUDY SELECTION Articles were selected at the authors' discretion based on areas of interest in childhood asthma treatment and progression into adulthood. RESULTS Uncontrolled asthma in early childhood can potentially have lasting effects on lung development, but it is unclear whether traditional interventions in very young children preserve lung function. Although not all children respond to standard interventions, certain asthma phenotypes have been identified that can help to understand which children may respond to a particular treatment. CONCLUSION Clinicians should monitor children's asthma control and pulmonary function over time to assess the long-term impact of an intervention and to minimize the effect of uncontrolled asthma, especially exacerbations, on lung development. New biologic therapies have shown promise in treating adults with severe, uncontrolled asthma, and some of these therapies are approved in the United States for children as young as age 6. However, knowledge gaps regarding the efficacy and safety of these treatments in younger children hamper our understanding of their effect on long-term outcomes.

Abstract
OBJECTIVE Despite the availability of effective treatments, asthma control in children and adolescents remains inadequate and rates of health care use are high. This follow-up to a recent review (O'Byrne et al, Eur Respir J. 2017;50[3]) examines a number of challenges in current pediatric asthma management compared with that of an adult perspective and discusses possible alternative strategies that might improve pediatric asthma management and control. DATA SOURCES The evidence base for this review is limited because, historically, much of the research has been performed in adults. STUDY SELECTIONS Not applicable. RESULTS Pediatric asthma management is complicated by variability in asthma severity and control and difficulty in measuring pulmonary function and airway inflammation. Current challenges in pediatric asthma management include the recommended initial therapy treating only the symptoms rather than the underlying inflammation and switching to controller therapy only when asthma subsequently worsens. CONCLUSION Alternative strategies that might improve pediatric asthma management and control include replacement of short-acting β2-agonist relievers by an inhaled corticosteroid plus a fast-acting β2-agonist (short-acting β2-agonist or fast- and long-acting β2-agonist) combination at Global Initiative for Asthma step 1 or 2 to ensure that patients receive an inhaled corticosteroid whenever they feel the need for symptomatic relief. Such an approach could eliminate the problem of learned overuse or over-reliance on short-acting β2-agonist reliever medication and address the other challenges in current pediatric asthma management. Clinical studies in pediatric patients or large studies involving a proportion of pediatric patients are required to provide the supporting evidence needed to help advance such new approaches and improve asthma control from a pediatric perspective.

Abstract
Objective: To investigate the clinical effect of budesonide nebulization in the treatment of ventilator associated pneumonia of newborns and its safety. Methods: Forty-five newborns who had ventilator associated pneumonia and were admitted into the Binzhou People’s Hospital between May 2014 and May 2015 were selected and included as an observation group. Moreover, another forty-five newborns who had ventilator associated pneumonia but did not undergo budesonide treatment in 2014 were randomly selected and included as a control group. Patients in the observation group were given budesonide suspension nebulization in addition to the conventional treatment. The evaluation indicators for therapeutic effect were compared between the two groups. The changes of head circumference, height and weight and death rate were observed by follow up after treatment. Results: The mechanical ventilation time, time for recovering from chest X-ray scan and hospitalization time of patients in the observation group were shorter than that of the control group, and the difference had statistical significance (P<0.05). The oxygen index of the patients in the observation group was significantly improved compared to that of the control group, and the difference had statistical significance (P<0.05). Patients in the two groups were followed up for six months after discharge. The head circumference, height and weight of the patients in the observation group in the 3rd and 6th month were compared to those of the control group, suggesting no significant differences (P>0.05). The cumulative death rate of the observation group in the 6th month after treatment was significantly lower than that of the control group, and the difference had statistical significance (P<0.05). Conclusion: Treating ventilator associated pneumonia of newborns with budesonide nebulization can effectively shorten mechanical ventilation time, time for recovering from chest X-ray scan and hospitalization time, improve pulmonary diffusion function and reduce the death rate, without affecting the growth and development of patients in the future.
