Active clinical trials for "Asthma"

This is a pilot study of the effect of montelukast in subjects with asthma who are 65 years old and older. Montelukast is a leukotriene receptor antagonist U.S. F.D.A. approved for the treatment of asthma in subjects who are 12 month old and older. This study is being done because there has been no placebo controlled study of montelukast focused on this group of patients. Elderly asthmatics have been mostly ignored in asthma studies. They are more likely to be underdiagnosed, undertreated, and hospitalized for asthma when compared to younger asthmatics. The pathophysiology of asthma in the elderly is typically different than in younger patients. This is a double-blind, placebo-controlled, crossover study. Investigators plan to enroll thirty subjects who have been diagnosed with asthma for at least one year, are non smoker, and did not smoke for more than 10 pack/year of tobacco products in their lifetime. After a run-in period of one week, the study subjects will take montelukast 10 mg orally for 8 weeks first and then placebo for 8 weeks, or vice versa. Primary objectives of this study are to evaluate the effect of montelukast on asthma symptoms assessed by daily symptom scores, the Asthma Control Test and the number of puffs of albuterol, and spirometric values (FEV1). Secondary objectives include studying whether montelukast affects peripheral blood eosinophils counts and serum IgE levels.

This study is the second Phase-II trial analyzing efficacy outcomes of PBF-680 in asthmatic subjects, following the supportive data from the proof-of-concept trial on the effect of PBF-680 on airway hyperresponsiveness to adenosine monophasphate (AMP). The purpose of the present study is to provide an assessment on the efficacy of a 5-day treatment course of once daily, orally administered, 10-mg PBF-680 doses, to attenuate "Late Asthmatic Responses" (LAR) as a primary efficacy outcome. The study also aims at analyzing the effect of the PBF-680 treatment course on airway inflammation-related outcomes including airway hyperresponsiveness to AMP at 24 h after allergen bronchoprovocation, plus nitric oxide fraction in exhaled air (FeNO) and airway inflammatory cells counts in induced sputum under the effect of an additional 10-mg PBF-680 dose on the 6th treatment period day. Overall, the study aims at providing evidence on the efficacy of PBF-680 on outcomes, particularly the LAR, that are well established to screen valid drugs for asthma maintenance therapy.

Primary Objective: To evaluate the effect of dupilumab, compared to placebo, on airway inflammation in participants with persistent asthma. Secondary Objective: To assess the safety, tolerability, and immunogenicity of dupilumab compared to placebo.

This is a blinded observer randomized controlled trial comparing two nebulizer devices. The objective of this study is to evaluate the efficacy of two different nebulizers.

Primary aim: Evaluating the effect of Asthmatuner on patients´ self-reported asthma control test (ACT/C-ACT)compared with conventional asthma management. Secondary aim: Evaluating patients´ health-related quality of life (HR-QoL) medical adherence by using Asthmatuner compared with conventional management. Total sample size: Stratified study population consisting of 43 females and males with diagnosed asthma at the age of at least 6 years pediatric specialist care and 43 females/males in primary care. Study design: This is a multi-centre, blinded, randomized controlled, cross-over trial over to at least 16 weeks. Subjects: Two stratified groups of participants with uncontrolled asthma will be recruited; (1) children and adolescents from Astrid Lindgren's Children's Hospital, Karolinska University Hospital, and (2) adolescents and adults from the primary health care sector in Stockholm, Sweden. The asthma control test (ACT/C-ACT) will be applied for evaluation of asthma control, a score less than 20 will be required for inclusion. Intervention: Asthmatuner is an app supporting self-management evaluating symptoms and lung function with external spirometry. The app gathers the information to define patients´ asthma control. Subsequently, Asthmatuner provides the patient with a treatment recommendation based on the individual treatment plan. Procedures: Participants are randomized (1:1) into the one of two-arms of asthma self-management with Asthmatuner - conventional or conventional - Asthmatuner. Questionnaires will collect information about asthma control, HR-QoL, Medicine adherence report scale (MARS) and history of medical health concerning health care utilization and personal costs and income. Analysis: The study hypothesis will be tested by examining difference in patients´ change in asthma control (ACT/C-ACT) and HR-QoL (PAQLQ/Mini-AQLQ). Results will be summarized at each management period as mean scores and analysed by paired t-tests.

This study is a double-blind, randomized, placebo-controlled, 2-period, crossover study to evaluate safety and PK of 3 doses of CVT 301 levodopa (l-dopa) in adults with asthma.

The combination of FF, an ICS and VI, an orally inhaled LABA has been developed as a once-daily combination therapy for the long-term maintenance treatment of asthma in adults and children >=12 years of age. Pivotal phase III studies have demonstrated the safety and efficacy of FF/VI in asthma. However, it is increasingly acknowledged that randomised clinical trials tend to be highly controlled and enrol a more highly selected subject population than is expected to be prescribed the medication post-approval. There is a need for data in a more representative population in close to a 'real life' conditions, where physicians have the ability to choose the best treatment in their view for any individual subject and adapt treatments to subjects' characteristics and response. This multi-center, open-label, randomized, parallel group study will evaluate the efficacy and safety of FF/VI compared with two usual ICS/LABA fixed combination (fluticasone propionate/salmeterol [FP/S] or budesonide/formoterol [BUD/F]) in subjects with persistent asthma, in a "close to real life" settings. FF/VI will be administered once-daily (QD) via ELLIPTA dry powder inhaler (DPI) and FP/S or BUD/F will be administered twice daily (BID) via DISKUS™ and TURBUHALER™ DPI respectively. ELLIPTA is a new powder inhaler designed to be easy to use. The total duration of subject participation will be approximately 6 months (24 weeks). ELLIPTA and DISKUS are registered trademarks of the GSK group of companies. TURBUHALER is a registered trademark of AstraZeneca.

The purpose of this study is to determine the efficacy of indacaterol 55µg once daily (and 27.5 µg twice) in QVA149 compared to 75 µg indacaterol monotherapy.

The purpose of this study is to find the best asthma treatment to add for Blacks who have asthma that is not well controlled on a low dose of inhaled steroid. This study will also try to find out if Black adults and children differ in how they respond to the medications used in this study.

This is a multi-center, randomized, double-blinded, placebo-controlled, crossover, single dose study in 24 pediatric patients (4-11 years old) with asthma. The entire study consists of (i) a Screening Visit and (ii) a Study Period with two (2) Study Visits. All study subjects must be properly consented, under adult supervision, and screened against the inclusion and exclusion criteria, at the Screening Visit.
