Active clinical trials for "Airway Obstruction"

This study is to evaluate the efficacy of a new therapy (Automatic Expiratory Positive Airway Pressure with intelligent Volume Assured Pressure Support (AutoEPAP iVAPS)) designed to treat respiratory insufficiency, respiratory failure and/or nocturnal hypoventilation with upper airway obstruction. The study will be performed in two phases: In a sleep unit and in the home environment. The new therapy will be compared against two existing ventilator therapies: "Spontaneous Timed (ST) mode" and "Intelligent Volume Assured Pressure Support (iVAPS)".

Chronic Obstructive Pulmonary Disease (COPD) is an increasing global health problem, which primarily increases among the female population. The purpose of this study is to perform in-depth clinical and molecular characterizations of early stage COPD patients, as well as healthy never-smoker and at-risk smoking control populations to identify molecularly related subgroups patients, including gender-related sub-phenotypes of COPD.

In asthma, the significant role of pathogenesis is chronic airway inflammation, bronchial hyperresponsiveness, and variable airflow obstruction. Asthma with irreversible or fixed airflow obstruction (FAO) is a clinical phenotype resulting from chronic airway inflammation with having longer disease duration, suggesting that airway remodeling contributes to the decline in lung function seen in individuals with asthma. Although this condition frequently occurs in patients with severe asthma, there are pieces of evidence occurring in those with mild to moderate asthma. According to previous research, low lung function, FEV1 less than 60% predicted, is a robust independent predictor of subsequent asthma attacks and other asthma outcomes, including asthma control and SABA use. In a recent study, the patients with mild to moderate asthma who received mild to medium dosed inhaled corticosteroid plus long-acting beta-2 agonist with or without asthma control showed evidence of FAO with or without bronchodilator reversibility. Therefore parasympathetic activity may be affected by FAO in those patients. The autonomic nervous system plays an essential role in asthma, especially from the parasympathetic, promoting bronchoconstriction and regulating airway inflammation and remodeling. This study hypothesizes that a cholinergic mechanism may play a significant role in FAO across patients with mild, moderate, and severe asthma. This might increase the fundamental evidence leading to early-step treatment with anti-cholinergic medication in early asthma severity driven by FAO.

Pilot Study of the Aerin Medical Wand used for Improvement in Nasal Breathing

This Phase II, double-blind, placebo-controlled, randomized, parallel-group study is designed to evaluate the efficacy, safety, and tolerability of huMAb OX40L administered to patients by IV infusion for the treatment of allergen-induced asthma.

The investigators are attempting to demonstrate a decrease in the frequency and severity of sedation-induced respiratory arrhythmias(central and obstructive apneas) with pharmacological pre-treatment in this pilot project and then eventually to understand the mechanisms behind this decrease. The efficacy and mechanisms of these treatments, while evaluated during sleep in Obstructed Sleep Apnea (OSA) patients, have not been systematically studied during sedation in either normal subjects or OSA patients. The agent to be assessed in this study in physostigmine versus placebo.

The purpose of this study is to evaluate how two different aerosol medications may improve airway function in infants with respiratory illness. We are using two different medications and comparing the difference in lung function after each medication. We will also be taking a nasal wash sample for VEGF. We will be using this in comparing how infants respond to the aerosol medications as well. We hope to help standardize medications used for infants with bronchiolitis and RSV.

Background. Recently, treatment of endobronchial hamartomas with interventional bronchoscopic methods has become possible. Although there are several reports of therapeutic benefits, the protocol of administration varies between centers and high recurrence rates continue to be a problem. In this study, the investigators aimed to show that cryotherapy applied to the root of the bronchial wall after removal of the intraluminal portion of endobronchial hamartoma with interventional bronchoscopic methods can prevent recurrences. Methods. Between 2012 and 2016, the treatment outcomes and long-term follow-up data of 21 consecutive patients with symptomatic endobronchial hamartomas treated by interventional bronchoscopic methods were prospectively recorded. After debulking, cryotherapy was applied to the root of the bronchial wall of all lesions. The data were analyzed retrospectively.

Evaluation of the Aerin Medical Device used for the treatment of nasal obstruction.

This is a multicenter, randomized, double-blind, placebo-controlled study designed to demonstrate the safety and efficacy of MILR1444A compared with placebo in reducing the airway reaction to an inhaled aeroallergen solution in adult patients with mild allergic asthma. The study will randomize approximately 24 patients at five study centers. In the event of patient discontinuation from the study, additional patients may be enrolled at the discretion of the Sponsor.
