Active clinical trials for "Asthma"

The purpose of this study is to determine whether RNS60, in combination with budesonide, is safe in mild to moderate asthmatics when taken by nebulization over a 28-day period, compared to a 28-day control period.

This will be a multi-center, randomized, placebo-controlled parallel-group study to evaluate nebulized fluticasone propionate (FP) dose response in adult subjects with partly controlled and uncontrolled asthma. Individual participation will be approximately 16 weeks, including 12 weeks of double-blind treatment.

The purpose of this study was to determine whether asthma control and reduced bronchial responsiveness could be achieved and maintained at a lower dose of inhaled corticosteroids with ADVAIR DISKUS BID or FP BID in adult and adolescent patients with persistent asthma

This was a 2-part study in participants with allergen-induced asthma. It included a procedural pilot component (Part 1). Part 1 tested the key procedures and timing of Part 2; no study drug was administered during Part 1. Part 2 included a pre-randomization placebo run-in (Period 1) and 3 treatment periods (Periods 2, 3, and 4) during which participants were randomized to receive double-blind placebo, MK-1029 60 mg or MK-1029 500 mg in a crossover design. The treatment periods were followed by a minimum 21-day washout. Part 2 assessed allergen-induced sputum eosinophils and allergen-induced late asthmatic response (LAR) compared to placebo.

This pilot intervention study will test the feasibility and acceptability and explore the outcomes of a primary care-based shared decision making (SDM) electronic medical record (EMR)-based portal that provides education, elicits and tracks patients/families' treatment concerns and goals, assesses symptoms and asthma control over time, and provides decision support to clinicians and families.

The INFANT study will test whether, in preschool children 12-59 months of age with persistent asthma, the following Step 2 asthma therapies will provide similar degrees of asthma control: Daily inhaled corticosteroid (ICS) treatment, Daily leukotriene receptor antagonist (LTRA) treatment, and As-needed ICS plus short-acting beta agonist (as-needed ICS/SABA) rescue treatment.

The investigators will study the biologic and chemical differences that cause the greater incidence, and severity of asthma in women as compared to men. Severe asthma affects boys more than girls, while severe asthma in adults is predominantly a disease of women. The investigators aim to identify the processes that occur in the body that are behind the onset of severe asthma in young women during the teenage years, and the resolution of severe asthma in boys. To further evaluate gender influences on asthma, asthmatic women at different stages of their menstrual cycle (period) will be also studied. The investigators aim to use biomarkers to develop testing procedures that will identify different types or characteristics of asthma in men and women; and to follow patients over time to uncover relevant clinical outcomes of biomarkers. The investigators anticipate that they will 1) develop clinically relevant tests to identify unique types or characteristics of asthma and severe asthma; 2) determine outcomes over time of biochemically-defined types of asthma; and 3) identify the reasons for why adult women are affected more than men with severe asthma.

Asthma is an extremely common disorder, which is becoming more prevalent. The purpose of this study is to examine how nocturnal lung volumes contribute to asthma severity, which may explain part of the link between asthma and obesity. The investigators seek to test the hypothesis that raising lung volumes during the night will improve asthma symptoms. The investigators work may lead to new targets for therapy.

The study looks at how vitamin D supplement will improve the severity of asthma and lung function as well as biomarkers in asthmatic children.

The investigators aim to pilot the role of school based intervention consisting of enhanced integrated pest management, classroom air purifiers and cleaning improves asthma morbidity.
