Marco-Ariño N, Jauhiainen A, Betts J, Da Silva CA. Complexity of design in early phase respiratory clinical trials; evaluating impact of primary endpoints and sponsor size. Contemp Clin Trials Commun 2021; 22:100793. [PMID: 34136720 PMCID: PMC8181183 DOI: 10.1016/j.conctc.2021.100793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 09/30/2020] [Accepted: 05/20/2021] [Indexed: 11/17/2022] Open
Abstract
Asthma and COPD represent most of the clinical trials in the respiratory area. The Primary Endpoint (PE) defines how trials are conducted. We hypothesised that small and mid-sized pharmaceutical companies may be innovative in the selection of their trial endpoints, to be time- and cost-effective. To test this, a record of industry-sponsored phase II trials in asthma, COPD and Asthma/COPD over 11 years was obtained. The type of PE and the influence these had on length, number of subjects and investigational trial sites were evaluated for the different disease categories. Differences in the type of PE used by large versus small/mid-sized companies were found for both asthma and COPD trials (p = 0.011 and 0.025), with sponsorship influencing the conduction of these. In asthma, studies sponsored by large companies were significantly longer than those from smaller companies (p = 0.0001). Additionally, large companies intended to recruit more subjects (asthma: p = 0.0048, COPD: p ≤ 0.0001) and use more investigational sites (asthma: p = 1 × 10-7, COPD: p = 1 × 10-5) than those from small and mid-size companies. A sub-analysis of the time and subject requirements associated with each type of PE did not provide an explanation for the differences observed. In conclusion, this exploratory analysis indicates differences in study size, duration and type of PE used by small/mid-sized and large companies. For some types of endpoints, differences in length and study size were found. However, it wasn't possible to attribute these differences between sponsors solely to the choice of PE, pointing out to the complexity of running clinical trials.

Abstract
RATIONALE Asthma is one of the most common chronic respiratory diseases in the United States. Several outdoor air pollutants have been associated with asthma morbidity. Previous studies of the effects of short-term air pollution exposure have been limited by potential exposure misclassification and limited spatial and temporal resolution of asthma outcome measures. OBJECTIVES We aimed to assess the association of short-term air pollutant exposure with the use of short-acting beta-2 agonists (SABA) for asthma by monitoring the time and place of occurrence with electronic medication monitors. METHODS In a cohort of adults and children with asthma (n = 287; 60% female), we deployed electronic medication monitors fitted to metered-dose inhalers to monitor SABA use, capturing the date, time and location of use. We assigned pollutant exposures based on each actuation's time and location (4-h mean measures for ozone and particulate matter of 2.5 µm or smaller (PM2.5)), assessed associations using generalized linear models and explored age-specific effects. MEASUREMENTS AND MAIN RESULTS Ambient ozone exposure was positively associated with SABA use (p = 0.01). Age-specific associations were identified (interaction p = 0.01), with a larger increase in SABA use for children (11.3%; 95% CI: 7.0%-18.2%) than adults (8.4%; 95% CI: 6.4%-11.0%) per IQR increase of ozone (16.8 ppb). CONCLUSIONS These findings support existing evidence that short-term exposure to ozone can cause morbidity in individuals with asthma, and suggest that ozone exposures below the current U.S. EPA standard may be associated with increased SABA use.

Abstract
Asthma is the leading chronic disease in children. Several studies have identified genetic biomarkers associated with susceptibility and severity in both adult and pediatric cases. In this study, we evaluated outcomes in 400 African American and European American pediatric cases all of whom were regular users of inhaled corticosteroids. Patients were stratified by genotype using two single nucleotide polymorphisms in the β-2-adrenergic receptor (ADRB2) gene - rs1042713 and rs1042714, previously associated with asthma outcome. These correspond to nonsynonymous single nucleotide polymorphisms at positions 16 [arginine to glycine (Arg16Gly); rs1042713] and 27 [glutamic acid to glutamine (Glu27Gln); rs1042714], which are relatively common (minor allele frequencies ∼40-50%), and have been well characterized in asthma pharmacogenetics. We controlled for adherence to the National Heart, Lung and Blood Institute guidelines using deep mining of electronic health record data to determine treatment course. We found no significant effect for rs1042713 (Arg16Gly) but did identify an effect for rs1042714, where participants homozygous for Gln27 had increased exacerbations while taking inhaled corticosteroids in comparison with those who were either heterozygous or homozygous for Glu27. This is consistent with previous studies and demonstrates for the first time that the Glu27 variant in the ADRB2 gene is associated with increased frequencies of asthma exacerbations. Moreover, this study also lends an important proof-of-principle on how electronic health records linked to genotype can be efficiently and systematically mined to delineate health outcomes.

Abstract
BACKGROUND More than 100 million individuals in the USA have been diagnosed with a chronic disease, yet chronic disease care has remained fragmented and of inconsistent quality. Improving chronic disease management has been challenging for primary care and internal medicine practitioners. Practice facilitation provides a comprehensive approach to chronic disease care. The objective is to evaluate the impact of practice facilitation on chronic disease outcomes in the primary care setting. METHODS This systematic review examined North American studies from PubMed, EMBASE, and Web of Science (database inception to August 2017). Investigators independently extracted and assessed the quality of the data on chronic disease process and clinical outcome measures. Studies implemented practice facilitation and reported quantifiable care processes and patient outcomes for chronic disease. Each study and their evidence were assessed for risk of bias and quality according to the Cochrane Collaboration and the Grade Collaboration tool. RESULTS This systematic review included 25 studies: 12 randomized control trials and 13 prospective cohort studies. Across all studies, practices and their clinicians were aware of the implementation of practice facilitation. Improvements were observed in most studies for chronic diseases including asthma, cancer (breast, cervical, and colorectal), cardiovascular disease (cerebrovascular disease, coronary artery disease, dyslipidemia, hypertension, myocardial infarction, and peripheral vascular disease), and type 2 diabetes. Mixed results were observed for chronic kidney disease and chronic illness care. DISCUSSION Overall, the results suggest that practice facilitation may improve chronic disease care measures. Across all studies, practices were aware of practice facilitation. These findings lend support for the potential expansion of practice facilitation in primary care. Future work will need to investigate potential opportunities for practice facilitation to improve chronic disease outcomes in other health care settings (e.g., specialty and multi-specialty practices) with standardized measures.

Abstract
BACKGROUND The longitudinal associations between psychological dysfunction (PD) and asthma exacerbations (AE) have not been adequately addressed. This study aimed to systematically assess the influence of PD on AE, and to determine whether different PD affects AE differentially. METHODS Electronic databases (PubMed, Cochrane library, Web of Science, Embase, and Ovid) were searched for prospective cohort studies on the influence of PD on AE in individuals with asthma. Relative risk (RR) and adjusted RR (RRadj) were pooled across studies. Subgroup analyses assessed the effects of different types of PD and the time-dependent response to the duration of PD exposure. RESULTS Ten articles that involved 31,432 adults with asthma with follow-up of 6.0-86.4 months were included. PD significantly increased the risk of AE [RRadj =1.06, 95% confidence interval (95%CI): 1.04-1.09, P<0.001], presenting as hospitalizations (RRadj =1.22, 95% CI: 1.12-1.34, P<0.001), unscheduled doctor visits (RR =4.26, 95% CI: 2.52-7.19), and emergency department (ED) visits (RRadj =1.06, 95% CI: 1.01-1.10, P=0.009) because of asthma. Depression significantly increased the risk of AE (RRadj =1.07, 95% CI: 1.04-1.11, P<0.001), presenting as hospitalizations (RRadj =1.26, 95% CI: 1.07-1.49, P=0.007) and ED visits (RRadj =1.06, 95% CI: 1.02-1.11, P=0.007) because of asthma. Anxiety was only associated with an increased risk of AE in pregnant women (RR =1.05, 95% CI: 1.01-1.08), possibly due to the small amount of data available on anxiety. The influence of PD on AE was only significant when the PD exposure time exceeded one year. CONCLUSIONS Co-morbid PD adversely affects AE, and there are differential effects of depression and anxiety. Asthmatic subjects with PD may benefit from more attention when establishing a treatment regimen in clinical practice.

Abstract
OBJECTIVES To review and evaluate the efficacy and safety of tian jiu therapy on san fu tian for adults with asthma. METHODS A literature search through August 31, 2013, was done to identify comparative studies evaluating effective rate, pulmonary function, immune response, recurrence rate, quality of life, and adverse events. The Cochrane Library, PubMed, EMBASE, and Chinese National Knowledge Infrastructure were searched; only randomized controlled trials with treatment groups using tian jiu therapy were included. Cochrane Collaboration's risk of bias tool and Review Manager software, version 5.2, were used for the data synthesis. RESULTS Six studies involving 657 patients were identified. tian jiu therapy was more effective than the control intervention (odds ratio [OR], 3.51; 95% confidence interval [CI], 2.05-6.00; p<0.00001; I(2)=18%). The treatment group had a bigger decrease in IgE level (standard mean difference [SMD], -1.40; 95% CI, -2.18 to -0.63; p=0.0004; I(2)=85%) and Eosinophil (Eos) level (SMD, -4.26; 95% CI, -6.28 to -2.23; p<0.00001; I(2)=91%) compared with the control group. Included studies had a high risk of bias. Few adverse effects were reported in the included studies, and no serious adverse responses occurred. Adverse effects did not result in any dropouts. CONCLUSIONS All studies indicated that tian jiu therapy has a positive effect on adults with asthma and that it is relatively safe because of its noninvasive nature. However, the limitations of the research design of the existing studies resulted in high risk of bias. More randomized controlled trials of better methodologic quality are needed to further confirm efficacy and safety of this therapy.

Abstract
Patient-generated health data are coming into broader use across the health care spectrum and hold great promise as a means to improve care and health outcomes. At the same time, rapid evolution in the social media and mobile health (mHealth) market has promoted an environment in which creation and transmission of personal health information is easy, quick, and appealing to patients. However, adoption of social media and mHealth by providers is hampered by legal and regulatory concerns with regard to data ownership and data use. This article defines common forms of patient-generated health data (PGHD) and describes how PGHD is used in clinical settings. It explores issues related to protection of personal health information, including that of children and adolescents, data security, and other potential barriers such as physician licensure. It also discusses regulatory and legal considerations providers and patients should consider before using social media and mobile health apps.

Abstract
Aim: Our objectives were to create a conceptual framework for development of standard outcome measures and to design and pilot test a tool for displaying outcome measures. Materials & methods: Information on outcome measures used in registries was gathered through stakeholder discussions, which informed the development of the outcome measurement framework and the related tool. Results: The outcome measurement framework is a conceptual model for how information relevant to evaluating patient outcomes may be defined and collected in a standard way for a broad range of health areas. The related tool facilitates collecting, displaying and searching for information on outcome measures. Conclusion: The model developed through this process offers a framework that can be used to define outcome measures in a standard way across medical conditions.

Abstract
OBJECTIVES While big data offers enormous potential for improving healthcare delivery, many of the existing claims concerning big data in healthcare are based on anecdotal reports and theoretical vision papers, rather than scientific evidence based on empirical research. Historically, the implementation of health information technology has resulted in unintended consequences at the individual, organizational and social levels, but these unintended consequences of collecting data have remained unaddressed in the literature on big data. The objective of this paper is to provide insights into big data from the perspective of people, social and organizational considerations. METHOD We draw upon the concept of persona to define the digital persona as the intersection of data, tasks and context for different user groups. We then describe how the digital persona can serve as a framework to understanding sociotechnical considerations of big data implementation. We then discuss the digital persona in the context of micro, meso and macro user groups across the 3 Vs of big data. RESULTS We provide insights into the potential benefits and challenges of applying big data approaches to healthcare as well as how to position these approaches to achieve health system objectives such as patient safety or patient-engaged care delivery. We also provide a framework for defining the digital persona at a micro, meso and macro level to help understand the user contexts of big data solutions. CONCLUSION While big data provides great potential for improving healthcare delivery, it is essential that we consider the individual, social and organizational contexts of data use when implementing big data solutions.

Abstract
Asthma is a chronic respiratory disorder canonically associated with type 2 airway inflammation as characterized by elevated levels of eosinophils, immunoglobulin E, and cytokines including interleukin (IL) 4, IL5, IL9, and IL13 and tumor necrosis factor (TNF) α. However, mounting evidence has shown that considerable heterogeneity exists in human asthma in terms of the nature and intensity of airway inflammation. While many asthma patients achieve acceptable control of symptoms with standard-of-care therapies such as β₂-adrenergic agonists and inhaled corticosteroids, a minority remains symptomatic despite maximal standard-of-care therapy and constitutes a significant unmet medical need. A growing number of investigational therapeutics under clinical development for asthma are biologic therapies that specifically target mediators of type 2 airway inflammation. In this chapter, we consider the biological functions of therapeutic targets in asthma and data from clinical trials of biologic agents directed against these targets. We discuss recent clinical trial results in terms of four key components of drug development: target selection, molecule selection, outcome selection, and patient selection, with particular attention paid to the emerging role of biomarkers in clinical development for asthma.

Abstract
Objectives Asthma trials suggest that patients reaching total disease control have an optimal Health Related Quality of Life (HRQoL). Moreover, rhinitis is present in almost 80% of asthmatics and impacts asthma control and patient HRQoL. We explored whether optimal HRQoL was reachable in a real-life setting, and evaluated the disease and patient related patterns associated to optimal HRQoL achievement. Methods and Findings Asthma and rhinitis HRQoL, illness perception, mood profiles, rhinitis symptoms and asthma control were assessed by means of validated tools in patients classified according to GINA and ARIA guidelines. Optimal HRQoL, identified by a Rhinasthma Global Summary (GS) score ≤20 (score ranging from 0 to 100, where 100 represents the worst possible HRQoL), was reached by 78/209 (37.32%). With the exception of age, no associations were found between clinical and demographic characteristics and optimal HRQoL achievement. Patients reaching an optimal HRQoL differed in disease perception and mood compared to those not reaching an optimal HRQoL. Asthma control was significantly associated with optimal HRQoL (χ2 = 49.599; p<0.001) and well-controlled and totally controlled patients significantly differed in achieving optimal HRQoL (χ2 = 7.617; p<0.006). Conclusion Approximately one third of the patients in our survey were found to have an optimal HRQoL. While unsatisfactory disease control was the primary reason why the remainder failed to attain optimal HRQoL, it is clear that illness perception and mood also played parts. Therefore, therapeutic plans should be directed not only toward achieving the best possible clinical control of asthma and comorbid rhinitis, but also to incorporating individualized elements according to patient-related characteristics.

Abstract
OBJECTIVE To estimate the prevalence of complementary and alternative medicine (CAM) use among children with current asthma. DESIGN We analyzed data from the Asthma Call Back Survey (ACBS) 2006-2008. ACBS is a follow-up to the state-based Behavioral Risk Factor Surveillance System (BRFSS) survey that collects information on asthma and related factors including CAM use for asthma. The survey is administered to the parents who report in a subset of BRFSS states that their children have asthma. 5435 children had current asthma and were included in this analysis. RESULTS Overall, 26.7% (95% confidence interval [CI]=24.5-29.0) of children with current asthma reported CAM use in the previous 12 months. Among them, the three most commonly used therapies were breathing techniques (58.5%; 95% CI=53.6-63.5), vitamins (27.3%; 95% CI=23.0-31.5), and herbal products (12.8%; 95% CI=9.2-16.4). Multivariate analysis of CAM use revealed higher adjusted odds ratios (aOR) among children who experienced cost barriers to conventional health care compared with children with no cost barrier (aOR=1.8; 95% CI=1.2-2.8). Children with poorly controlled asthma were most likely to use all types of CAM when compared to their counterpart with well-controlled asthma: aOR=2.3 (95% CI=1.6-3.3) for any CAM; aOR=1.7 (95% CI=1.2-2.6) for self-care based CAM; and aOR=4.4 (95% CI=1.6-9.3) for practitioner-based CAM. CONCLUSIONS Children with poorly controlled asthma are more likely to use CAM; this likelihood persists after controlling for other factors (including parent's education, barriers to conventional health care, and controller medication use). CAM is also more commonly used by children who experienced cost barriers to conventional asthma care. CAM use could be a marker to identify patients who need patient/family education and support thus facilitate improved asthma control.
