RESUMO

BACKGROUND: Morbidity from asthma is disproportionately higher among black patients than among white patients, and black patients constitute the minority of participants in trials informing treatment. Data indicate that patients with inadequately controlled asthma benefit more from addition of a long-acting beta-agonist (LABA) than from increased glucocorticoids; however, these data may not be informative for treatment in black patients. METHODS: We conducted two prospective, randomized, double-blind trials: one involving children and the other involving adolescents and adults. In both trials, the patients had at least one grandparent who identified as black and had asthma that was inadequately controlled with low-dose inhaled glucocorticoids. We compared combinations of therapy, which included the addition of a LABA (salmeterol) to an inhaled glucocorticoid (fluticasone propionate), a step-up to double to quintuple the dose of fluticasone, or both. The treatments were compared with the use of a composite measure that evaluated asthma exacerbations, asthma-control days, and lung function; data were stratified according to genotypic African ancestry. RESULTS: When quintupling the dose of fluticasone (to 250 µg twice a day) was compared with adding salmeterol (50 µg twice a day) and doubling the fluticasone (to 100 µg twice a day), a superior response occurred in 46% of the children with quintupling the fluticasone and in 46% of the children with doubling the fluticasone and adding salmeterol (P = 0.99). In contrast, more adolescents and adults had a superior response to added salmeterol than to an increase in fluticasone (salmeterol-low-dose fluticasone vs. medium-dose fluticasone, 49% vs. 28% [P = 0.003]; salmeterol-medium-dose fluticasone vs. high-dose fluticasone, 49% vs. 31% [P = 0.02]). Neither the degree of African ancestry nor baseline biomarkers predicted a superior response to specific treatments. The increased dose of inhaled glucocorticoids was associated with a decrease in the ratio of urinary cortisol to creatinine in children younger than 8 years of age. CONCLUSIONS: In contrast to black adolescents and adults, almost half the black children with poorly controlled asthma had a superior response to an increase in the dose of an inhaled glucocorticoid and almost half had a superior response to the addition of a LABA.

RESUMO

BACKGROUND: In many patients with mild, persistent asthma, the percentage of eosinophils in sputum is less than 2% (low eosinophil level). The appropriate treatment for these patients is unknown. METHODS: In this 42-week, double-blind, crossover trial, we assigned 295 patients who were at least 12 years of age and who had mild, persistent asthma to receive mometasone (an inhaled glucocorticoid), tiotropium (a long-acting muscarinic antagonist), or placebo. The patients were categorized according to the sputum eosinophil level (<2% or ≥2%). The primary outcome was the response to mometasone as compared with placebo and to tiotropium as compared with placebo among patients with a low sputum eosinophil level who had a prespecified differential response to one of the trial agents. The response was determined according to a hierarchical composite outcome that incorporated treatment failure, asthma control days, and the forced expiratory volume in 1 second; a two-sided P value of less than 0.025 denoted statistical significance. A secondary outcome was a comparison of results in patients with a high sputum eosinophil level and those with a low level. RESULTS: A total of 73% of the patients had a low eosinophil level; of these patients, 59% had a differential response to a trial agent. However, there was no significant difference in the response to mometasone or tiotropium, as compared with placebo. Among the patients with a low eosinophil level who had a differential treatment response, 57% (95% confidence interval [CI], 48 to 66) had a better response to mometasone, and 43% (95% CI, 34 to 52) had a better response to placebo (P = 0.14). In contrast 60% (95% CI, 51 to 68) had a better response to tiotropium, whereas 40% (95% CI, 32 to 49) had a better response to placebo (P = 0.029). Among patients with a high eosinophil level, the response to mometasone was significantly better than the response to placebo (74% vs. 26%) but the response to tiotropium was not (57% vs. 43%). CONCLUSIONS: The majority of patients with mild, persistent asthma had a low sputum eosinophil level and had no significant difference in their response to either mometasone or tiotropium as compared with placebo. These data provide equipoise for a clinically directive trial to compare an inhaled glucocorticoid with other treatments in patients with a low eosinophil level.

RESUMO

BACKGROUND: PT027 is a fixed-dose combination of albuterol (salbutamol) and budesonide in a single pressurized metered-dose inhaler. OBJECTIVE: To evaluate the efficacy and safety of albuterol/budesonide compared with placebo in patients with asthma and exercise-induced bronchoconstriction (EIB). METHODS: In this randomized, double-blind, 2-period, single-dose crossover study, adolescents and adults with asthma and EIB (defined by ≥20% decrease from pre-exercise challenge forced expiratory volume in 1 second [FEV1]) were randomized to albuterol/budesonide (180/160 µg) followed by placebo (n = 29) or the reverse sequence (n = 31). Subjects were stratified by background therapy (as-needed short-acting ß2-agonist alone or low-to-medium dose inhaled corticosteroid plus as-needed short-acting ß2-agonist). FEV1 was measured 5 minutes pre-dose, 30 minutes postdose (5 minutes pre-exercise challenge [baseline]), and 5, 10, 15, 30, and 60 minutes postexercise. The primary end point was maximum percentage fall from baseline in FEV1 up to 60 minutes postexercise challenge. RESULTS: Least squares mean maximum percentage fall in FEV1 up to 60 minutes postexercise challenge was 5.45% with albuterol/budesonide vs 18.97% with placebo (difference, -13.51% [95% confidence interval, -16.94% to -10.09%]; P < .001). More subjects were fully protected (maximum percentage fall in FEV1 post-exercise challenge < 10%) with albuterol/budesonide than with placebo (78.3% vs 28.3%; P < .001). The treatment effect was consistent irrespective of background inhaled corticosteroid therapy, and albuterol/budesonide was well tolerated. CONCLUSION: In adolescents and adults with asthma and EIB, a single dose of albuterol/budesonide 180/160 µg taken approximately 30 minutes before exercise was significantly more effective than placebo in preventing EIB.

RESUMO

BACKGROUND: A novel, inhalation-driven, multidose dry powder inhaler (MDPI) that does not require coordination of actuation with inhalation has been developed. OBJECTIVE: To evaluate the efficacy and safety of albuterol MDPI versus placebo MDPI after chronic dosing in children with asthma. METHODS: This phase III, double-blind, parallel-group study included children with asthma (ages, 4-11 years) with forced expiratory volume in 1 second (FEV1) of 50-95% of predicted. After a 14-day run-in period wherein the patients continued their current asthma therapy and received single-blind placebo MDPI, they were randomized to albuterol MDPI 90 µg per inhalation, two inhalations four times daily (total daily dose, 720 µg), or placebo for 3 weeks. Pulmonary function was assessed on days 1 and 22. Efficacy and safety were evaluated by measuring the baseline-adjusted percent-predicted FEV1 (PPFEV1) area under the time curve over 6 hours (AUC0-6) after the dose and adverse events, respectively. RESULTS: The full analysis set included 184 patients. Patients treated with albuterol MDPI versus patients treated with placebo MDPI had significantly greater baseline-adjusted PPFEV1 AUC0-6 over 3 weeks (least squares mean difference, 25.0%•hour, which favored albuterol; p < 0.001). The benefit of albuterol (mean change in PPFEV1) was evident 5 minutes after dosing and lasted several hours; the maximal effect was noted 1 to 2 hours after dosing. Albuterol MDPI was well tolerated. CONCLUSIONS: In children with persistent asthma, albuterol MDPI improved pulmonary function significantly better than placebo MDPI over 3 weeks of treatment. Clinical efficacy was evident within 5 minutes of dosing and maintained for >2 hours. Four times daily administration was well tolerated.

RESUMO

BACKGROUND: Asthma is characterized by a complex interaction of inflammatory mediators. The prostaglandin D2 receptor, chemoattractant receptor-homologous molecule on Th2 cells (CRTH2), plays a pivotal role in the pathogenesis of allergic airway inflammation. OBJECTIVE: To ealuate the efficacy, safety, and pharmacokinetics of BI 671800, a CRTH2 antagonist, when added to inhaled corticosteroid therapy in adult patients with symptomatic asthma. METHODS: In this phase IIa, 12-week, randomized, double-blind, three-period, four-treatment, incomplete block crossover trial, BI 671800 was administered either as a single 400-mg dose in the morning (A.M.) or evening (P.M.), or 200 mg twice daily (A.M. and P.M.) versus placebo, together with fluticasone propionate (44 µg, two inhalations twice daily). The primary end point was the change from baseline in trough forced expiratory volume in 1 second percentage predicted after 4 weeks. The secondary end point was the change in Asthma Control Questionnaire score from baseline. RESULTS: A total of 108 patients were randomized and treated. After 4 weeks, the adjusted mean (± SE) treatment differences for the primary end point versus placebo were 0.08 ± 0.62%, 0.28 ± 0.61%, and 0.67 ± 0.63% for BI 671800 at 200 mg twice daily, 400 mg A.M., and 400 mg P.M., respectively (not statistically significant). No statistically significant or clinically meaningful differences in the Asthma Control Questionnaire score were observed versus placebo. Each treatment was well tolerated. CONCLUSION: BI 671800 at a dose of 400 mg administered for 4 weeks with fluticasone propionate did not provide clinical improvement in patients with asthma; reasons for this are unclear, but it may be due to insufficient inhibition of the CRTH2 receptor at the doses used.

RESUMO

BACKGROUND: Pharmacologic treatment is a mainstay of allergy therapy and many caregivers use over-the-counter antihistamines for the treatment of seasonal allergic rhinitis (SAR) symptoms in children. OBJECTIVE: To assess the efficacy and safety of cetirizine 10 mg syrup versus loratadine 10 mg syrup versus placebo syrup in a randomized double-blind study of children, ages 6-11 years, with SAR. METHODS: This randomized, double-blind, parallel-group, placebo-controlled study was conducted at 71 U.S. centers during the spring tree and grass pollen season. After a 1-week placebo run-in period, qualified subjects were randomized to once-daily cetirizine 10 mg (n = 231), loratadine 10 mg (n = 221), and placebo (n = 231) for 2 weeks. The primary efficacy end point was change from baseline in the subject's mean reflective total symptom severity complex (TSSC) score over 14 days. RESULTS: Children treated with cetirizine experienced significantly greater TSSC score reductions versus children treated with placebo over 14 days (least square mean change, -2.1 versus -1.6; p = 0.006). The differences in TSSC score improvement over 14 days between the cetirizine versus loratadine groups (-2.1 versus -1.8; p = 0.124) and between the loratadine versus placebo groups (-1.8 versus -1.6; p = 0.230) were not statistically significant. Predominant adverse events in the cetirizine, loratadine, and placebo groups were headache (3.5, 3.6, and 3.1%, respectively) and pharyngitis (3.5, 2.7, and 3.5%, respectively). Somnolence was reported in three subjects (1.3%) treated with cetirizine and in none of the other subjects. CONCLUSION: Cetirizine 10 mg was statistically significantly more efficacious than placebo in the treatment of SAR symptoms in children ages 6-11 years. Symptom improvement was not significantly different between the loratadine 10 mg and placebo groups.

RESUMO

BACKGROUND: A Phase II, multicentre, randomised, double-blind, placebo-controlled, crossover trial comparing the 24-h forced expiratory volume in 1 s (FEV1) time profile after 3 weeks' treatment with once-daily (QD) or twice-daily (BID) olodaterol (at the same total daily dose) versus placebo delivered via Respimat® in patients with moderate to severe asthma. METHODS: Patients were randomised to different sequences of olodaterol with 2-week washout, either as a total daily dose of 5 µg (5 µg QD [AM] or 2.5 µg BID) or placebo, or 10 µg (10 µg QD [AM] or 5 µg BID) or placebo. Primary end point was FEV1 area under the curve from 0 to 24 h (AUC0-24) response (defined as change from study baseline FEV1) after 3 weeks. Key secondary end points were FEV1 AUC0-12 and AUC12-24 responses. RESULTS: Two hundred and six patients received treatment. All olodaterol treatments demonstrated statistically significant improvements in FEV1 AUC0-24 response at 3 weeks versus placebo (p < 0.0001); adjusted mean treatment difference versus placebo was 0.191 L for olodaterol 2.5 µg BID (95 % confidence interval [CI] 0.152, 0.229), 0.150 L for 5 µg QD (95 % CI 0.111, 0.189), 0.228 L for 5 µg BID (95 % CI 0.190, 0.266) and 0.209 L for 10 µg QD (95 % CI 0.170, 0.247). These results were supported by the key secondary end points. Olodaterol 5 µg QD provided numerically lower mean values for 24-h bronchodilation than olodaterol 2.5 µg BID (p = 0.0465), with no statistically significant difference between treatment with olodaterol 10 µg QD and 5 µg BID. No relevant differences in morning and evening peak expiratory flow or Asthma Control Questionnaire scores at 3 weeks were observed between different doses and regimens. Adverse events were generally mild to moderate and comparable between groups. CONCLUSIONS: All doses and dose frequencies provided adequate 24-h bronchodilation superior to placebo. Based on the results of this study, it would be reasonable to include both posologies of 5 µg olodaterol daily (5 µg QD or 2.5 µg BID, both delivered in two puffs per dose from the Respimat® inhaler) in subsequent studies. Further studies are necessary to confirm the optimum dosing regimen in asthma. No safety concerns were identified. TRIAL REGISTRATION: ClinicalTrials.gov NCT01311661.

RESUMO

BACKGROUND: Asthma management in an outpatient setting is best accomplished by clinical evaluation coupled with spirometry and symptom evaluation, but these assessments do not provide information about airway inflammation. Exhaled nitric oxide (fraction of exhaled nitric oxide [FeNO]) measures T-helper cell type 2-mediated airway inflammation and may be a useful adjunct in asthma management. OBJECTIVE: To determine whether the use of FeNO in the specialist management of asthma results in more effective and cost-effective treatment decisions. METHODS: Fifty subjects 7 to 60 years old with established asthma participated in this observational study. Subjects were evaluated by clinical examination, spirometry, and symptom assessment using the Asthma Control Test, and clinicians estimated airway inflammation and made treatment decisions based on these assessments. Then, FeNO was measured, and changes in therapy based on FeNO levels were documented. The estimated cost impact of using FeNO was calculated presuming ongoing FeNO use in patient management. RESULTS: Without FeNO, the clinician's assessment of airway inflammation was incorrectly classified in 50% of subjects. FeNO results substantially altered treatment decisions in more than one third of subjects, notably medication augmentation in 10 (20%) and medication decreases in 8 (16%). Use of FeNO in addition to standard of care was estimated to save $629 per subject per year. CONCLUSION: Measurement of FeNO augments routine clinical assessment of asthma by measuring airway inflammation. Knowledge of FeNO affects medication treatment decisions to augment or decrease pharmacotherapy, which has important long-term asthma management implications, most notably the potential to lower the costs and morbidity associated with 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

IMPORTANCE: In asthma and other diseases, vitamin D insufficiency is associated with adverse outcomes. It is not known if supplementing inhaled corticosteroids with oral vitamin D3 improves outcomes in patients with asthma and vitamin D insufficiency. OBJECTIVE: To evaluate if vitamin D supplementation would improve the clinical efficacy of inhaled corticosteroids in patients with symptomatic asthma and lower vitamin D levels. DESIGN, SETTING, AND PARTICIPANTS: The VIDA (Vitamin D Add-on Therapy Enhances Corticosteroid Responsiveness in Asthma) randomized, double-blind, parallel, placebo-controlled trial studying adult patients with symptomatic asthma and a serum 25-hydroxyvitamin D level of less than 30 ng/mL was conducted across 9 academic US medical centers in the National Heart, Lung, and Blood Institute's AsthmaNet network, with enrollment starting in April 2011 and follow-up complete by January 2014. After a run-in period that included treatment with an inhaled corticosteroid, 408 patients were randomized. INTERVENTIONS: Oral vitamin D3 (100,000 IU once, then 4000 IU/d for 28 weeks; n = 201) or placebo (n = 207) was added to inhaled ciclesonide (320 µg/d). If asthma control was achieved after 12 weeks, ciclesonide was tapered to 160 µg/d for 8 weeks, then to 80 µg/d for 8 weeks if asthma control was maintained. MAIN OUTCOMES AND MEASURES: The primary outcome was time to first asthma treatment failure (a composite outcome of decline in lung function and increases in use of ß-agonists, systemic corticosteroids, and health care). RESULTS: Treatment with vitamin D3 did not alter the rate of first treatment failure during 28 weeks (28% [95% CI, 21%-34%] with vitamin D3 vs 29% [95% CI, 23%-35%] with placebo; adjusted hazard ratio, 0.9 [95% CI, 0.6-1.3]). Of 14 prespecified secondary outcomes, 9 were analyzed, including asthma exacerbation; of those 9, the only statistically significant outcome was a small difference in the overall dose of ciclesonide required to maintain asthma control (111.3 µg/d [95% CI, 102.2-120.4 µg/d] in the vitamin D3 group vs 126.2 µg/d [95% CI, 117.2-135.3 µg/d] in the placebo group; difference of 14.9 µg/d [95% CI, 2.1-27.7 µg/d]). CONCLUSIONS AND RELEVANCE: Vitamin D3 did not reduce the rate of first treatment failure or exacerbation in adults with persistent asthma and vitamin D insufficiency. These findings do not support a strategy of therapeutic vitamin D3 supplementation in patients with symptomatic asthma. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01248065.

RESUMO

BACKGROUND: This is the first study, to our knowledge, to evaluate the ocular effects of an intranasal corticosteroid during 2 years of treatment for perennial allergic rhinitis (PAR). OBJECTIVE: To assess ocular safety in adult and adolescent patients 12 years and older with PAR after 2 years of continuous treatment with fluticasone furoate nasal spray (FFNS), 110 µg once daily, and placebo. METHODS: This was a 2-year, randomized, double-blind, placebo-controlled study of once-daily FFNS, 110 ìg, and placebo in 548 patients 12 years and older with PAR. The primary ocular safety end points were time to first occurrence of an event for the Lens Opacities Classification System, Version III (LOCS III), posterior subcapsular opacity (PSO) and time to first occurrence of an event for intraocular pressure (IOP). RESULTS: On the basis of survival analyses, the difference between the treatment groups for time to first occurrence of a LOCS III PSO and time to first occurrence of an IOP event was not statistically significant (P = .39 and P = .34, respectively). Changes from baseline in visual acuity, LOCS III PSO, cortical opacity, LOCS III nuclear opacity and nuclear color, IOP, and horizontal cup-to-disc similar between treatment groups. There were no ophthalmic-related adverse events of LOCS III PSO or IOP that led to early withdrawal. The most common drug-related adverse event was epistaxis (FFNS, 28%; placebo, 14%). CONCLUSION: These data neither support nor negate current recommendations for regular ophthalmic monitoring in patients treated with intranasal corticosteroids.

A new nasal aerosol solution formulation of ciclesonide containing a hydrofluoroalkane propellant (CIC-HFA) delivered via a metered-dose inhaler is currently in clinical development as a potential treatment for allergic rhinitis (AR). This study evaluated the efficacy and tolerability of CIC-HFA 74- or 148-microgram doses compared with placebo in patients with perennial AR (PAR). Patients ≥12 years of age with a ≥ 2-year history of PAR were randomized in a placebo-controlled, double-blind, parallel-group, multicenter study to CIC-HFA 74 micrograms, CIC-HFA 148 micrograms, or placebo q.d. in the morning (A.M.) for 26 weeks. Change from baseline in reflective total nasal symptom score (rTNSS), instantaneous total nasal symptom score (iTNSS), and rhinoconjunctivitis quality-of-life questionnaire with standardized activities (RQLQ[S]) in patients with baseline RQLQ of ≥3.00 were evaluated for the first 6 weeks of treatment. Treatment-emergent adverse events (TEAEs) were monitored throughout the study. Eleven hundred eleven patients were randomized. CIC-HFA 74- and 148-microgram doses showed statistically significant improvements in rTNSS (least squares [LS] mean change, 0.70 and 0.54, respectively; p ≤ 0.001 versus placebo for both), iTNSS (LS mean change, 0.58 and 0.42, respectively; p < 0.05 versus placebo for both), and RQLQ[S] (LS mean change, 0.55 and 0.37, respectively; p < 0.01 versus placebo for both) from baseline. The overall incidence of TEAEs was comparable between the CIC-HFA treatment groups and placebo. In this study, once-daily treatment with CIC-HFA 74- or 148-micrograms showed statistically significant improvements in nasal symptoms of PAR. Both doses were well tolerated.

RESUMO

Many patients with allergic rhinitis (AR) have uncontrolled symptoms despite available treatment options. This study was designed to evaluate the efficacy and safety of MP29-02 (a novel intranasal formulation of fluticasone propionate [FP] and azelastine [AZ] hydrochloride), compared with monotherapy with FP, AZ, and placebo sprays for the treatment of seasonal allergic rhinitis (SAR). This 2-week randomized, double-blind, placebo-controlled trial was conducted in 779 patients with moderate-to-severe SAR. Treatments were administered 1 spray/nostril twice daily in the same vehicle and delivery device. Daily doses of AZ and FP were 548 and 200 micrograms, respectively. The primary efficacy variable was the 12-hour reflective total nasal symptom score (rTNSS), consisting of nasal congestion, sneezing, itchy nose, and runny nose. Secondary efficacy variables were (1) 12-hour reflective individual nasal symptom scores; (2) onset of action; (3) 12-hour reflective total ocular symptom score (rTOSS), including itchy eyes, watery eyes, and red eyes; and (4) the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) overall score. MP29-02 significantly reduced the mean rTNSS from baseline by -5.54 points compared with FP (-4.55; p = 0.038), AZ (-4.54; p = 0.032), and placebo (-3.03; p < 0.001), improving the rTNSS by 39% beyond the contribution of FP. All individual nasal symptoms contributed to the efficacy of MP29-02. Onset of action was within 30 minutes. MP29-02 significantly improved rTOSS compared with placebo, provided a clinically important improvement in the overall RQLQ score, and was well tolerated. In this study, MP29-02 provided more complete symptom relief than two widely used first-line AR treatments and was well tolerated.

RESUMO

Intranasal corticosteroids are recommended as first-line therapy for the treatment of the symptoms of persistent allergic rhinitis (AR). Since the phase-out of chlorofluorocarbon nasal aerosols, intranasal corticosteroids have been available only as aqueous nasal sprays. This study was designed to assess the efficacy, safety, and quality-of-life benefits of beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol in subjects with perennial AR (PAR). After a 7- to 21-day placebo run-in period, eligible subjects aged ≥12 years with PAR were randomized to 6 weeks of once-daily treatment with BDP nasal aerosol at 320 µg or placebo. Reflective and instantaneous total nasal symptom scores (rTNSS and iTNSS, respectively), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score, and physician-assessed total nasal symptom score were evaluated. The primary end point was change from baseline in average morning (A.M.) and evening (P.M.) subject-reported rTNSS over the 6-week treatment period. Safety and tolerability were also assessed. Treatment with BDP nasal aerosol showed significantly greater improvement in average A.M. and P.M. rTNSS compared with placebo (mean treatment difference, -0.84; 95% confidence interval, -1.2, -0.5; p < 0.001). Greater improvements in rTNSS were reported as early as day 1 and were maintained throughout the 6-week treatment period with the exception of day 2. Greater improvements were seen for all four individual nasal symptoms (nasal congestion, nasal itching, rhinorrhea, and sneezing) with BDP nasal aerosol compared with placebo. Similarly, significant improvements were seen in average A.M. and P.M. iTNSS (p < 0.001) and RQLQ score (p = 0.001) with BDP nasal aerosol compared with placebo. In addition, BDP nasal aerosol treatment was well tolerated, and its safety profile was comparable to that of placebo. This clinical study indicated that treatment with BDP nasal aerosol provides statistically significant and clinically meaningful nasal symptom relief accompanied by improved quality of life in subjects with PAR. Additionally, treatment with BDP nasal aerosol was well tolerated with a safety profile comparable to that of placebo. This study was part of the clinical trial NCT01134705 registered in www.ClinicalTrials.gov.

RESUMO

PURPOSE: Indacaterol is a novel, once daily, inhaled ultra-long-acting ß2-agonist for the treatment of chronic obstructive pulmonary disease (COPD). Here we compared the 24-h spirometry profile of once daily indacaterol 300 µg with that of placebo and twice daily salmeterol 50 µg in patients with COPD. METHODS: This randomized, multicenter, placebo-controlled, crossover study comprised three 14-day treatment periods (with 14-day washouts). Patients (male/female ≥ 40 years) with moderate-to-severe COPD were randomized to receive double-blind indacaterol 300 µg or placebo once daily, or open-label salmeterol 50 µg twice daily. The primary outcome measure was 24-h post-dose (trough) FEV1 (mean of FEV1 at 23 h 10 min and 23 h 45 min post-indacaterol dose) after 14 days. FEV1 was assessed at multiple time points on Days 1 and 14 of each treatment period. Safety and tolerability were also monitored. RESULTS: Of 68 randomized patients, 61 completed. Trough FEV1 (primary endpoint) on Day 14 for indacaterol was 200 mL higher than placebo (p < 0.001), exceeding the prespecified minimum clinically important difference (120 mL), and was 90 mL higher than for salmeterol (p = 0.011). After Day 1, trough FEV(1) for indacaterol was 150 mL higher than placebo (p < 0.001). Indacaterol provided superior bronchodilation compared with placebo (p < 0.001) across the full 24-h assessment period on Days 1 and 14. In addition, on both days, indacaterol provided superior FEV1 compared with salmeterol (p < 0.05) at many post-baseline time points, including 5 min post-dose. All treatments were well tolerated. CONCLUSIONS: Once daily indacaterol 300 µg produced effective sustained 24-h bronchodilation from the first dose, an efficacy profile superior to placebo and twice daily salmeterol. Given its effective bronchodilation with once daily dosing, indacaterol is likely to be a useful treatment option for patients with moderate-to-severe COPD.

RESUMO

INTRODUCTION: Inhaled delivery devices that are easy to use and facilitate dose tracking may lead to improved patient satisfaction and adherence. Patient satisfaction with a metered-dose inhaler (MDI) with an integrated dose counter containing a fixed-dose mometasone furoate/formoterol combination (MF/F MDI dose counter) was evaluated in subjects with persistent asthma or chronic obstructive pulmonary disease. METHODS: In this multicenter study (N = 272, age range: 12-92 years), subject experience and satisfaction with MDI devices was evaluated using baseline and poststudy surveys. Subjects responded to the baseline survey based on their previous MDI experience, then received MF/F MDI 100/10 µg with the integrated dose counter for 4 weeks before completing the poststudy survey. This evaluation was part of a broader study objective to assess performance of the MF/F MDI dose counter. RESULTS: At baseline, 52% of subjects reported being extremely satisfied with their previous MDI. After using the MF/F MDI dose counter, a relative increase of 43% in overall satisfaction was observed. Approximately 90% of subjects agreed the MF/F dose counter helped them track doses and was easy to use; >80% agreed the inhaler was of good quality and well designed. Subjects agreed the dose counter relieved anxiety about running out of medication (68%) or taking a subtherapeutic dose (65%). Nearly 80% of subjects had no reservations about the MF/F MDI dose counter, and most subjects stated they would request it from their physician (66%) and recommend it to a friend (75%). CONCLUSIONS: The MF/F MDI dose counter was found to be easy to use and have overall high patient satisfaction.

RESUMO

BACKGROUND: Interleukin-9 (IL-9)-targeted therapies may offer a novel approach for treating asthmatics. Two randomized placebo-controlled studies were conducted to assess the safety profile and potential efficacy of multiple subcutaneous doses of MEDI-528, a humanized anti-IL-9 monoclonal antibody, in asthmatics. METHODS: Study 1: adults (18-65 years) with mild asthma received MEDI-528 (0.3, 1, 3 mg/kg) or placebo subcutaneously twice weekly for 4 weeks. Study 2: adults (18-50 years) with stable, mild to moderate asthma and exercise-induced bronchoconstriction received 50 mg MEDI-528 or placebo subcutaneously twice weekly for 4 weeks. Adverse events (AEs), pharmacokinetics (PK), immunogenicity, asthma control (including asthma exacerbations), and exercise challenge test were evaluated in study 1, study 2, or both. RESULTS: In study 1 (N = 36), MEDI-528 showed linear serum PK; no anti-MEDI-528 antibodies were detected. Asthma control: 1/27 MEDI-528-treated subjects had 1 asthma exacerbation, and 2/9 placebo-treated subjects had a total of 4 asthma exacerbations (one considered a serious AE). In study 2, MEDI-528 (n = 7) elicited a trend in the reduction in mean maximum decrease in FEV1 post-exercise compared to placebo (n = 2) (-6.49% MEDI-528 vs -12.60% placebo; -1.40% vs -20.10%; -5.04% vs -15.20% at study days 28, 56, and 150, respectively). Study 2 was halted prematurely due to a serious AE in an asymptomatic MEDI-528-treated subject who had an abnormal brain magnetic resonance imaging that was found to be an artifact on further evaluation. CONCLUSIONS: In these studies, MEDI-528 showed an acceptable safety profile and findings suggestive of clinical activity that support continued study in subjects with mild to moderate asthma.

RESUMO

Olopatadine hydrochloride nasal spray 0.6% (OLO) and azelastine nasal spray 137 micrograms (AZE) are effective in treating allergic rhinitis and AZE is indicated for nonallergic vasomotor rhinitis (VMR). This study evaluates the relative safety and efficacy of OLO and AZE in patients with VMR. This randomized, double-blind, parallel-group, multicenter study compared OLO (an investigational use) with AZE over 14 days in patients (n = 129) ≥12 years of age with chronic VMR. Efficacy included the severity of nasal symptom scores. Safety included adverse events (AEs) and nasal examinations. Patient perceptions of treatment satisfaction and changes in allergy condition were determined using the Treatment Satisfaction Questionnaire for Medication and Patient Global Assessment scores. In the OLO and AZE groups, reflective scores for individual nasal symptoms (nasal congestion, rhinorrhea, postnasal drip, and sneezing) and total nasal VMR symptom scores decreased significantly from baseline to day 14 (p < 0.05). No significant between-group differences were observed (p > 0.05). No serious AEs were reported in either group. Overall, 22 and 20 AEs were reported in the OLO and AZE groups, respectively. The most common AE was taste disturbance, reported by three (5.3%) and six (10.3%) patients in the OLO and AZE groups, respectively. Patients in both groups reported similar treatment satisfaction scores and a majority of patients in both groups perceived an overall improvement in their rhinitis condition. OLO has a similar efficacy and safety profile to AZE for the management of VMR in patients ≥12 years of age.

RESUMO

BACKGROUND: Concerns exist that regular long-acting beta(2)-adrenergic agonist (LABA) therapy may increase the risk of serious asthma-related events. OBJECTIVE: To assess risks of formoterol-containing versus non-LABA treatment by using a large asthma database. METHODS: This analysis included all blind, parallel-arm, randomized, active-controlled and/or placebo-controlled AstraZeneca-sponsored asthma studies with formoterol-containing and non-LABA comparator arms. Serious adverse events were assessed for inclusion in all-cause death, asthma-related death, asthma-related intubation, and asthma-related hospitalization categories by using blind adjudication. Data were combined across trials; relative risk (RR) was assessed by using Mantel-Haenszel methods. RESULTS: Data were from 13,542 formoterol-randomized and 9968 non-LABA patients 4 years or older (42 trials), of whom 93% and 89%, respectively, received inhaled corticosteroid as part of randomized treatment or allowed medication. Incidence of all-cause death was low (n=3 and n=4, respectively), with numerically lower all-cause deaths/1000 patient-treatment years in the formoterol-treated group (0.53) versus the non-LABA group (0.82) (RR, 0.64; 95% confidence interval [CI], 0.14-2.92). No asthma-related deaths and 1 asthma-related intubation (formoterol-treated group) occurred. Asthma-related hospitalizations/1000 patient-treatment years were lower numerically in the formoterol-treated group (12.1) versus the non-LABA group (16.4) (RR, 0.73; 95% CI, 0.54-1.01), with fewer study discontinuations in the formoterol-treated group (12.7% vs 15.4%, respectively; RR, 0.79; 95% CI, 0.74-0.85). Relative to non-LABA, increasing daily formoterol dose (>/=4.5, 9, 18, 36 mug) did not increase the rate or incidence of asthma-related hospitalization. CONCLUSION: No evidence of increased risk of asthma-related hospitalization, no asthma-related deaths, and a low incidence of all-cause death and asthma-related intubation were seen with formoterol-containing versus non-LABA treatment.

RESUMO

BACKGROUND AND OBJECTIVES: Co-suspension Delivery™ Technology has been developed for the administration of albuterol sulfate pressurised inhalation suspension via metered-dose inhaler (AS MDI, PT007). We assessed the efficacy and safety of AS MDI versus Proventil® in order to determine the optimal dose of AS MDI to take to Phase III clinical trials. METHODS: ASPEN (NCT03371459) and ANTORA (NCT03364608) were Phase II, randomised, crossover, multicentre studies of AS MDI versus Proventil® in patients with persistent asthma. In ASPEN, 46 patients received cumulative-dose treatments (90 µg/inhalation using 1 + 1 + 2 + 4 + 8 inhalations at 30-minute intervals) in 1 of 2 possible sequences: AS MDI/Proventil or Proventil/AS MDI. In ANTORA, 86 patients were randomised to one of 10 treatment sequences of AS MDI (90 µg or 180 µg), placebo MDI, or Proventil (90 µg or 180 µg). The primary endpoints were baseline-adjusted forced expiratory volume in 1 second (FEV1) 30 minutes after each cumulative dose (ASPEN) and change from baseline in FEV1 area under the curve from 0 to 6 h (ANTORA). Safety was assessed in both studies. RESULTS: In ASPEN, AS MDI was equivalent to Proventil (within pre-specified bounds of ± 200 mL) following cumulative doses of albuterol up to 1440 µg for the primary endpoint. In ANTORA, 90 µg and 180 µg doses of AS MDI and Proventil were significantly superior to placebo MDI (p < 0.0001), and AS MDI was non-inferior to Proventil at both doses, based on a margin of 100 mL. No new safety concerns were identified. CONCLUSION: The effects of albuterol delivered via AS MDI and Proventil on bronchodilation were equivalent, supporting the selection of AS MDI 180 µg to be taken into Phase III clinical trials, either alone or in combination with an inhaled corticosteroid.
