Efficacy and safety of ipratropium bromide/albuterol compared with albuterol in patients with moderate-to-severe asthma: a randomized controlled trial.

ABSTRACT: Many patients with asthma require frequent rescue medication for acute symptoms despite appropriate controller therapies. Thus, determining the most effective relief regimen is important in the management of more severe asthma. This study's objective was to evaluate whether ipratropium bromide/albuterol metered-dose inhaler (CVT-MDI) provides more effective acute relief of bronchospasm in moderate-to-severe asthma than albuterol hydrofluoroalkaline (ALB-HFA) alone after 4 weeks.In this double-blind, crossover study, patients who had been diagnosed with asthma for ?1 year were randomized to two sequences of study medication "as needed" for symptom relief (1-7 day washout before second 4-week treatment period): CVT-MDI/ALB-HFA or ALB-HFA/CVT-MDI. On days 1 and 29 of each sequence, 6-hour serial spirometry was performed after administration of the study drug. Co-primary endpoints were FEV1 area under the curve (AUC0-6) and peak (post-dose) forced expiratory volume in 1 s (FEV1) response (change from test day baseline) after 4 weeks. The effects of "as needed" treatment with ALB-HFA/CVT-MDI were analyzed using mixed effect model repeated measures (MMRM).A total of 226 patients, ?18 years old, with inadequately controlled, moderate-to-severe asthma were randomized. The study met both co-primary endpoints demonstrating a statistically significant treatment benefit of CVT-MDI versus ALB-HFA. FEV1 AUC0-6h response was 167 ml for ALB-HFA, 252 ml for CVT-MDI (p <0.0001); peak FEV1 response was 357 ml for ALB-HFA, 434 ml for CVT-MDI (p <0.0001). Adverse events were comparable across groups.CVT-MDI significantly improved acute bronchodilation over ALB-HFA alone after 4 weeks of "as-needed" use for symptom relief, with a similar safety profile. This suggests additive bronchodilator effects of ?2-agonist and anticholinergic treatment in moderate-to-severe, symptomatic asthma.ClinicalTrials.gov No.: NCT00818454 ; Registered November 16, 2009.

Project description:BackgroundIpratropium bromide/albuterol Respimat inhaler (CVT-R) was developed as an environmentally friendly alternative to ipratropium bromide/albuterol metered-dose inhaler (CVT-MDI), which uses a chlorofluorocarbon propellant.ObjectiveThe objective of this study was to evaluate patient satisfaction, device usage, and long-term safety of CVT-R compared to CVT-MDI, and to the simultaneous administration of ipratropium bromide hydrofluoroalkane (HFA; I) and albuterol HFA (A) metered-dose inhalers as dual monotherapies (I + A).DesignThis is a 48-week, open-label, randomized, active-controlled, parallel-group study (n = 470) comparing CVT-R to CVT-MDI and to I + A.ParticipantsPatients were at least 40 years of age, diagnosed with chronic obstructive pulmonary disease (COPD), and current or exsmokers.InterventionsPatients were randomized to receive: (1) CVT-R, one inhalation four times daily (QID); or (2) CVT-MDI, two inhalations QID; or (3) I + A two inhalations of each inhaler QID.Main measuresPatient Satisfaction and Preference Questionnaire (PASAPQ) performance score (primary endpoint) and adverse events.Key resultsPASAPQ performance score was significantly higher (CVT-R versus CVT-MDI, 9.6; and CVT-R versus I + A, 6.2; both P < 0.001) when using CVT-R compared to CVT-MDI or I + A at all visits starting from week 3, while CVT-MDI and I + A treatment groups were similar. Time to first COPD exacerbation was slightly longer in the CVT-R group compared to the other treatment groups, although it did not reach statistical significance (CVT-R versus CVT-MDI, P = 0.57; CVT-R versus I + A, P = 0.22). Rates of withdrawal and patient refusal to continue treatment were lower in CVT-R compared with CVT-MDI and I + A groups (CVT-R versus CVT-MDI, P = 0.09; CVT-R versus I + A, P = 0.005). The percentage of patients reporting adverse events and serious adverse events was similar across all three treatment groups.ConclusionCVT-R is an effective, environmentally friendly inhaler that provides patients with a high level of user satisfaction and may positively impact clinical outcomes while having no adverse impacts on patients using the device.

Project description:BackgroundA combination of ipratropium bromide (IB) and salbutamol is commonly used to treat asthma in children and adolescents; however, there has been a lack of consistency in its usage in clinical practice.ObjectiveTo evaluate the efficacy and safety of IB + salbutamol in the treatment of asthma in children and adolescents.MethodsThe MEDLINE, Embase, and Cochrane Library as well as other Chinese biomedical databases (including China Biological Medicine Database, Chinese National Knowledge Infrastructure, Chongqing VIP, and Wanfang Chinese language bibliographic database) were systematically searched from the earliest record date to September 2020 for randomized controlled trials in children and adolescents (≤18 years) with asthma who received IB + salbutamol or salbutamol alone. The primary outcomes included hospital admission and adverse events. A random effects model with a 95% confidence interval (CI) was used. Subgroup analysis was performed according to age, severity of asthma, and co-interventions with other asthma controllers. This study was registered with PROSPERO.ResultsOf the 1061 studies that were identified, 55 met the inclusion criteria and involved 6396 participants. IB + salbutamol significantly reduced the risk of hospital admission compared with salbutamol alone (risk ratio [RR] 0.79; 95% CI 0.66-0.95; p = 0.01; I2 = 40%). Subgroup analysis only showed significant difference in the risk of hospital admission in participants with severe asthma exacerbation (RR 0.73; 95% CI 0.60-0.88; p = 0.0009; I2 = 4%) and moderate-to-severe exacerbation (RR 0.69; 95% CI 0.50-0.96; p = 0.03; I2 = 3%). There were no significant differences in the risk of adverse events between IB + salbutamol group and salbutamol alone group (RR 1.77; 95% CI 0.63-4.98).ConclusionIB + salbutamol may be more effective than salbutamol alone for the treatment of asthma in children and adolescents, especially in those with severe and moderate to severe asthma exacerbation. The very low to high quality of evidence indicated that future well-designed double-blind RCTs with large sample are needed for research on evaluating the effectiveness of IB + salbutamol treatment for asthma in children and adolescents.

Project description:INTRODUCTION:Dupilumab, a fully human anti-IL-4Rα monoclonal antibody, inhibits signaling of both interleukin (IL)-4 and IL-13, which are key drivers of type 2-mediated inflammation. Dupilumab is approved in the EU, USA, and other countries for the treatment of adults with inadequately controlled moderate-to-severe atopic dermatitis. Following positive phase 2 results in asthma, the phase 3 Liberty Asthma QUEST trial was initiated to provide further evidence for dupilumab efficacy and safety in patients with uncontrolled, moderate-to-severe asthma. METHODS:Liberty Asthma QUEST is a phase 3, multinational, multicenter, randomized, double-blind, placebo-controlled, parallel-group trial (NCT02414854) in patients with persistent asthma who are receiving continuous treatment with inhaled corticosteroids (ICS) plus one or two other asthma controller medicines. A total of 1902 patients (aged ≥ 12 years) were randomized in a 2:2:1:1 ratio to receive 52 weeks of add-on therapy with subcutaneously administered dupilumab 200 or 300 mg every 2 weeks or matched placebo. The study consisted of a 4 ± 1-week screening period, 52-week randomized treatment period, and 12-week post-treatment follow-up period. All patients continued to receive their prescribed ICS plus up to two additional controller medications. The primary efficacy endpoints were annualized rate of severe exacerbation events during the 52-week treatment period and absolute change from baseline in pre-bronchodilator FEV1 at week 12. CONCLUSION:Uncontrolled asthma patients with persistent symptoms represent a population of significant unmet need, for whom new treatments are required. Patients with severe asthma are at high risk of asthma exacerbations, and face an accelerated decline in lung function and impaired quality of life. QUEST examines the efficacy of dupilumab in this at-risk patient population; it is the largest placebo-controlled study in uncontrolled, moderate-to-severe asthma with a biologic agent to date, and the only phase 3 study of a biologic therapy of asthma that enrolled patients irrespective of baseline type 2 inflammatory biomarker levels.

Project description:BackgroundRoflumilast is a targeted inhibitor of phosphodiesterase (PDE)-4 and has been approved for treatment of severe chronic obstructive pulmonary disease for more than a decade. Generic versions are available in the United States. PDE-4 is involved in the psoriasis pathogenesis, but the efficacy and safety of oral roflumilast in patients with psoriasis have not previously been studied.MethodsA company-independent, multicenter, randomized, double-blind, placebo-controlled trial (ClinicalTrials.govNCT04549870). Patients were randomized 1:1 to receive monotherapy with oral roflumilast 500 μg once daily or placebo. At week 12, placebo patients were switched to open-label roflumilast through week 24. The primary endpoint was a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI75) at week 12.FindingsIn all, 46 patients were randomized (roflumilast, n = 23; placebo, n = 23). At week 12, significantly more patients in the active arm achieved PASI75 (8 of 23 patients [35%]) vs. placebo (0 of 23 patients [0%], with a difference vs. placebo of 8 [35%] patients, 95% CI: 3 [13%]-13 [57%] patients) (p = 0.014). At week 24, 15 (65%), 10 (44%), 5 (22%), and 2 (9%) of patients treated with roflumilast from week 0 had PASI50, PASI75, PASI90, and PASI100 responses (key secondary endpoints), respectively. The most prevalent, drug-related adverse events in both treatment groups were transient gastrointestinal symptoms, weight-loss, headache, and insomnia. A total of three patients (roflumilast n = 2; placebo, n = 1) discontinued therapy due to adverse events.InterpretationOral roflumilast was efficacious and safe in treating moderate-to-severe plaque psoriasis over 24 weeks. With generic versions available, this drug may represent an inexpensive and convenient alternative to established systemic psoriasis treatments.FundingFinancial support was received from Herlev and Gentofte Hospital, University of Copenhagen, and independent grants from private foundations in Denmark. No pharmaceutical company, including the market authorization holder of roflumilast, was involved in the study at any point.
