RESUMO

BACKGROUND: The safety of long-acting ß-agonists added to inhaled corticosteroids for the treatment of persistent asthma has been controversial. OBJECTIVE: We sought to determine whether administering formoterol in combination with mometasone furoate increases the risk of serious asthma outcomes (SAOs) compared with mometasone furoate alone. This clinical trial is registered as NCT01471340. METHODS: We conducted a 26-week, randomized, double-blind trial in adolescent and adult patients (≥12 years) with persistent asthma in 35 countries with the primary objective of evaluating whether mometasone furoate-formoterol increases the risk of SAOs (adjudicated hospitalization, intubation, or death) compared with mometasone furoate alone. The key efficacy end point was asthma exacerbation (composite of hospitalization of ≥24 hours, emergency department visits of <24 hours requiring systemic corticosteroids, or use of systemic corticosteroids for ≥3 consecutive days). RESULTS: Among 11,729 patients (mometasone furoate-formoterol, n = 5,868; mometasone furoate, n = 5,861), a total of 81 SAOs, all asthma-related hospitalizations, were observed in 71 patients: 45 events from 39 patients receiving mometasone furoate-formoterol and 36 events from 32 patients receiving mometasone furoate. The hazard ratio for the first SAO in the mometasone furoate-formoterol versus mometasone furoate group was 1.22 (95% CI, 0.76-1.94; P = .411). Asthma exacerbation occurred in 1,487 patients: 708 receiving mometasone furoate-formoterol and 779 receiving mometasone furoate. The hazard ratio for the first asthma exacerbation in the mometasone furoate-formoterol versus mometasone furoate group was 0.89 (95% CI, 0.80-0.98; P = .021). CONCLUSIONS: The addition of formoterol to mometasone furoate maintenance therapy did not increase the risk of serious asthma-related events and reduced the risk of asthma exacerbation.

RESUMO

The effect of cetirizine on quality of life (QOL) in subjects with perennial allergic rhinitis (PAR) has been previously evaluated using generic instruments. While generic QOL tools are used across various conditions, disease-specific instruments evaluate the impact of treatment on areas that are affected by that particular condition. This study evaluated the effect of cetirizine on symptom severity and health-related QOL, using a disease-specific instrument, in adults with PAR. This randomized, double-blind, placebo-controlled study was conducted at 15 U.S. centers outside the pollen allergy season. After a 1-week placebo run-in period, qualified subjects aged 18-65 years with PAR were randomized to once-daily cetirizine 10 mg (n = 158) or placebo (n = 163) for 4 weeks. Change from baseline in total symptom severity complex (TSSC) and overall Rhinitis Quality of Life Questionnaire (RQLQ) scores were primary efficacy end points. Cetirizine produced significantly greater improvements in mean TSSC for each treatment week (p < 0.05) and for the entire 4-week treatment period (p = 0.005) compared with placebo. After 4 weeks, cetirizine-treated subjects reported significantly greater overall improvement in RQLQ scores compared with placebo-treated subjects (p = 0.004). After 1 week, cetirizine produced significant improvements in the nasal symptoms, practical problems, and activities RQLQ domain scores compared with placebo (p < 0.05). After 4 weeks, cetirizine-treated subjects reported significant reductions in these RQLQ domain scores and in emotion domain scores compared with placebo-treated subjects (p < 0.05). Cetirizine 10 mg daily produced significant improvements in symptom severity and allergic rhinitis-related QOL compared with placebo in adults with PAR.

RESUMO

BACKGROUND: Limited data exist on the relative impact of moderate and severe exacerbations on asthma control and impairment. OBJECTIVE: To explore data from the CAPTAIN trial to evaluate the relationship between first moderate or severe exacerbation and changes in lung function, symptoms, physical activity limitation scores, and short-acting ß2-agonist (SABA) usage to determine the clinical relevance of moderate events. METHODS: CAPTAIN was a phase IIIA 24- to 52-week, multicenter, international, randomized controlled trial evaluating efficacy and safety of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI in patients with uncontrolled asthma on inhaled corticosteroid/long-acting ß2-agonist. Outcomes reported include first postrandomization exacerbation event by severity (wk 1-52), frequency and duration of moderate and severe exacerbations, and time course of changes over ± 14-day peri-exacerbation period for lung function, symptoms, limitations, and SABA use. RESULTS: Of the intent-to-treat population (n = 2,436), 550 patients (23%) continued to 52 weeks. There were 529 moderate and 546 severe exacerbations. Lung function changes were similar, but symptom, physical activity limitation scores, and SABA use were higher, for severe versus moderate exacerbations. Lung function decline preceded increases in symptom, physical activity limitation scores, and SABA use, irrespective of exacerbation severity. Lung function variables, limitation scores, and SABA use returned to pre-exacerbation baseline after approximately 8 to 12 days for both exacerbation severities. CONCLUSIONS: Whereas severe events were associated with greater impact on symptoms, physical activity limitations, and SABA use, onset and time to resolution were generally similar for moderate and severe events. Both exacerbation severities represent clinically important deteriorations comprising clinical and functional changes.

RESUMO

OBJECTIVE: Although interventions have been shown to alleviate symptoms in most patients suffering from asthma, only one-third of asthma patients have disease that is well-controlled. The purpose of this study is to investigate whether partly and uncontrolled asthmas are associated with increased costs for asthma-related healthcare utilization compared to well-controlled asthma and to determine whether these associations differed across racial groups. METHODS: We classified respondents from the Asthma Insights and Management survey into those with well-, partly and uncontrolled asthma and compared utilization of healthcare services and costs among these groups, as well as between whites and non-whites. RESULTS: Respondents categorized as having asthma that was not well-controlled reported lower income levels, higher rates of unemployment and more trouble paying for healthcare; similar results were found in analyses stratified by race. Patients whose asthma was partly or uncontrolled had greater use of asthma-related medications and medical services compared to patients whose asthma was well-controlled. Total unadjusted and adjusted costs were greater in patients whose asthma was classified as partly and uncontrolled. Similar results were found in analyses stratified on race. Across all levels of asthma control, non-whites had higher rates of utilization of emergency rooms and urgent care facilities and had greater rates of hospitalizations compared to whites. CONCLUSIONS: Our findings indicate that patients with asthma that is not well-controlled utilized more healthcare resources and had greater medical costs, despite lacking of health insurance which may suggest less access to care.

RESUMO

BACKGROUND: Despite effective medications, asthma remains a significant burden to the US health care system. OBJECTIVE: To determine whether partly and uncontrolled asthma in respondents to the Asthma Insights and Management (AIM) survey was associated with adverse outcomes (such as visits to health care professionals and medication use) compared with well-controlled asthma. METHODS: The AIM survey, conducted in 2009, included 2,500 patients with asthma who were 12 years or older. We classified patients into levels of control and compared use of health care services and limitations of activities in patients whose asthma was well controlled vs those with partly and uncontrolled asthma. RESULTS: Patients who reported lower income and educational status and lacked health insurance were less likely to have had well-controlled asthma. Respondents with uncontrolled asthma were more likely to report ever use of oral steroids (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.9-3.2) and over-the-counter medicine (OR, 2.7; 95% CI, 2.0-3.7) compared with patients whose asthma was well controlled. Respondents with partly and uncontrolled asthma were also significantly more likely to report ever visiting physicians, specialists, or the emergency department or being hospitalized for asthma compared with those whose asthma was well controlled (ORs ranging from 2.1 to 5.6). Finally, respondents whose asthma was uncontrolled had increased odds (ORs ranging from 14 to 34) of reporting that asthma limited their activities compared with respondents whose asthma was well controlled. CONCLUSION: Patients with partly and uncontrolled asthma defined by international guidelines reported use of significantly more health care resources and greater limitations of their daily activities compared with patients whose asthma was well controlled.

RESUMO

BACKGROUND: Surveys have consistently shown that many patients with asthma do not have their disease well controlled. OBJECTIVES: The CHOICE (Comprehensive Survey of Healthcare Professionals and Asthma Patients Offering Insight on Current Treatment Gaps and Emerging Device Options) survey was designed to evaluate the current status of inhalation devices used in asthma treatment, but questions also were included about asthma severity and control. METHODS: A total of 1,000 patients with asthma were interviewed about their use of inhalation devices and asthma-related burden, medication use, and hospital/emergency care. Based on the responses to these questions, asthma severity and control were categorized using methods established in the Expert Panel Report III (EPR 3). RESULTS: Almost half (490) of the patients with asthma participating in the CHOICE survey were not using controller medications. Most of those not using controllers (79%) had persistent asthma; 47% had either mild or moderate persistent asthma. Of those on controllers (510), only 14.3% were well controlled. Acute care utilization was greater for patients with persistent asthma than those with intermittent asthma and for patients with not well and poorly controlled asthma than those with well-controlled asthma. CONCLUSION: The CHOICE survey is particularly pertinent clinically, because it demonstrates for the first time, using EPR 3 methods, the current extent of poor asthma control in the United States. This situation falls far short of national asthma management targets.

RESUMO

BACKGROUND: This study investigated the efficacy and safety of a new asthma therapy combining fluticasone propionate and formoterol fumarate (fluticasone/formoterol; flutiform®), administered twice daily (b.i.d.) via a single aerosol inhaler, compared with its individual components administered separately and placebo, in patients with mild-to-moderate asthma. METHODS: Patients aged ≥ 12 years were evenly randomised to 12 weeks of treatment with fluticasone/formoterol (100/10 µg b.i.d.), fluticasone (100 µg b.i.d.), formoterol (10 µg b.i.d.), or placebo, in this double-blind, parallel group, multicentre study. The three co-primary endpoints were: a) change in forced expiratory volume in the first second (FEV(1)) from morning pre-dose at baseline to pre-dose at week 12 for the comparison with formoterol; b) change in FEV(1) from morning pre-dose at baseline to 2 hours post-dose at week 12 for the comparison with fluticasone, and c) time to discontinuation due to lack of efficacy from baseline to week 12 for the comparison with placebo. Safety was assessed based on adverse events, clinical laboratory tests and vital sign evaluations. RESULTS: Statistically significant differences were demonstrated for all the three co-primary endpoints. Fluticasone/formoterol combination therapy showed significantly greater improvements from baseline to end of study in the change in pre-dose FEV(1) compared with formoterol (Least Squares (LS) mean treatment difference: 0.101 L; 95% Confidence Interval (CI): 0.002, 0.199; p = 0.045) and the change in pre-dose compared with 2 hours post-dose FEV(1) versus fluticasone (LS mean treatment difference: 0.200 L; 95% CI: 0.109, 0.292; p < 0.001). The time to discontinuation due to lack of efficacy was significantly longer for patients in the combination therapy group compared with those receiving placebo (p = 0.015). Overall, the results from multiple secondary endpoints assessing lung function, asthma symptoms, and rescue medication use supported the superior efficacy of the combination product compared with fluticasone, formoterol, and placebo. The fluticasone/formoterol combination therapy had a good safety and tolerability profile over the 12 week treatment period. CONCLUSIONS: Fluticasone/formoterol had a good safety and tolerability profile and showed statistically superior efficacy for the three co-primary endpoints compared to fluticasone, formoterol, and placebo, in adolescents and adults with mild-to-moderate asthma.

RESUMO

Past asthma surveys have shown suboptimal management and control of asthma in the United States. No major survey of asthma management has been conducted since the Third Expert Panel Report for the National Asthma Education and Prevention Program (NAEPP) guidelines on diagnosis and treatment of asthma (August 2007). This study was designed to report asthma management and control results from the Asthma Insight and Management survey of U.S. patients and physicians. A telephone-based survey was conducted during 2009 in 2500 patients with asthma, aged ≥12 years, and 309 physicians (104 allergists, 54 pulmonologists, 101 family practitioners, and 50 internists). Patients' asthma control perceptions (71% "completely controlled" or "well controlled") were inconsistent with their NAEPP control level as determined by self-reported symptoms (29% well controlled). Patients and physicians had low expectations for effective asthma management; patients considered asthma well managed if rescue medication was used three times per week (46%), urgent care visits occurred twice per year (67%), or emergency department visits occurred once per year (60%). Asthma-related syncope, seizure, intensive care unit admission, and intubation were associated with uncontrolled asthma based on NAEPP guidelines. Respiratory specialists (allergists/pulmonologists) implemented asthma management recommendations more than other physicians surveyed. However, only 22% of patients visited a specialist for usual asthma care and 48% had never visited a specialist. Despite detailed NAEPP guidance, asthma management and control in U.S. patients is unsatisfactory. Improved asthma control assessment (impairment and risk) and implementation of NAEPP management recommendations are needed to improve asthma control and outcomes.

RESUMO

Updated guidelines and new treatments for asthma have become available since the last major survey of asthma management in the United States was completed ∼11 years ago. The Asthma Insight and Management (AIM) survey was conducted to assess the current status of asthma burden in the United States. A geographically stratified screening of 60,682 households provided a national sample of 2500 patients with current asthma (2186 adults aged ≥18 years; 314 adolescents aged 12-17 years). A national sample of 1004 adults without current asthma was interviewed for comparison with the adult asthma population, and 309 asthma health care providers were surveyed for their opinions about the burden of asthma. Asthma prevalence in the United States was estimated at 8%. Twice as many adult asthma patients rated their health as "only fair," "poor," or "very poor," or experienced limitations in activity because of health problems, compared with the general population. Asthma also frequently caused negative emotional symptoms in patients. Most patients experienced asthma throughout the year (63%) and symptoms within the 4 weeks before the summer survey (68%). Overall, 41% of patients responded that asthma interfered with their/their child's life "some" or "a lot". During the year before the survey, 69% of patients experienced at least one severe asthma episode. Asthma burden in the United States remains high despite the availability of updated treatment guidelines and new therapies. Asthma care in the United States remains suboptimal, indicating the need for continued improvements in patient management.

RESUMO

Long-term achievement of asthma control is dependent in part on the use of mutually understandable asthma terminology in all verbal and written patient-physician communications. Using data from the Asthma Insight and Management (AIM) survey, the objective of this analysis is to provide a contemporary depiction of asthma deterioration terminology as used by current asthma patients and physicians in the United States. As part of the 2009 AIM survey, current asthma patients (≥12 years of age; weighted n = 2499) and physicians (n = 309) were queried about their recognition, understanding, and/or use of the terms "asthma attack," "asthma flare-up," and "asthma exacerbation" in telephone interviews. Nearly all patients had heard the term "asthma attack" (97%), but relatively few had heard the term "asthma exacerbation" (24%); 71% had heard "asthma flare-up." In contrast, physicians reported using the term "asthma attack" least (65%) and the term "asthma exacerbation" most (77%) when discussing asthma with their patients; 70% reported using "asthma flare-up." Among patients familiar with "asthma flare-up" and "asthma exacerbation" (n = 502), only 38% said that the terms mean the same thing; nearly all physicians (94%) said that the terms mean the same thing. Collectively, data from the AIM survey suggest that patients and physicians use different asthma deterioration terminology and, more importantly, that they do not necessarily understand each other's terms. Standardizing asthma deterioration terminology may help optimize asthma patient-physician communication to improve patient understanding of written asthma action plans and therefore, enhance patient outcomes.
