10 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists and long acting muscarinic antagonists. We are interested in determining whether the large and/or small airways are the predominant site of airflow limitation. We are also interested in determining whether intrinsic small airways obstruction and/or loss of lung elastic recoil is responsible for expiratory airflow limitation and to what extent may be attributed to loss of lung elastic recoil vs decreased airway conductance in peripheral airways. We are also interested to evaluate the role of varying doses of inhaled corticosteroids to suppress large and small airway inflammation using exhaled nitric oxide as surrogate markers of inflammation. For comparison purposes, spirometry and measurements of exhaled nitric oxide will also be obtained if possible during a naturally occurring exacerbation of asthma. High resolution thin section CT of the lung will also be obtained. Analysis will evaluate integrity of the lung parenchyma as to absence and or presence of emphysema and extent of emphysema using voxel quantification. We will also investigate optical coherence tomography to detect clinically unsuspected emphysema. We will also obtain autopsy material when available in asthmatics who expire. Will also measure serum periostin as a marker of inflammation by collaborating with Genetech in San Francisco.
This study is a two strata, dose escalation Phase I clinical trial designed to assess the safety and determine the maximal tolerated dose (MTD) of allogenic cord tissue derived MSCs (cMSCs, stratum 1) and allogeneic, interferon-γ primed bone marrow MSCs (γMSCs, stratum 2). Each stratum is designed to independently accrue 3 children at a dose level 1 of 2x106 cells/kg and 6 children at dose level 2 of 10x106 cells/kg, resulting in 9 children in each stratum. The primary objectives are to determine the safety and toxicity of allogeneic cord tissue derived MSCs and allogeneic interferon-γ primed bone marrow derived MSCs.
This study will evaluate the efficacy, safety of two dose levels of CBP-201 in patients with moderate to severe persistent asthma with Type 2 inflammation.
This study aims to investigate the effect of omalizumab on the number of tissue eosinophils and other markers of airway inflammation and remodeling, including thickness of the lamina reticularis, in moderate to severe asthmatics with persistent symptoms and evidence of airway inflammation despite treatment with inhaled corticosteroids and long acting beta-agonists. This study will also investigate the correlation between systemic and pulmonary inflammation, and the correlation between clinical outcomes and changes within the tissue, to assist in the future identification of patients with tissue eosinophilia and their response to treatment, without the need for invasive bronchoscopy.
This study was designed to assess the safety of indacaterol (300 µg and 600 µg (2 x 300 μg capsules) once daily \[od\]), compared with salmeterol (50 μg twice a day \[b.i.d.\]), over 26 weeks, in patients with moderate to severe persistent asthma.
OBJECTIVE: Determine whether home asthma telemonitoring using store-and-forward technology improves outcomes when compared to in-person, office-based visits.
Nitric oxide is an important marker of airway inflammation in asthma. Nitric oxide may have a protective role in patients with moderate to severe asthma. The investigators believe that a natural amino acid, L-arginine, that augments nitric oxide levels can decrease asthma exacerbations and improve the asthma care of moderate to severe asthma patients. This study is a randomized, placebo controlled trial in which subjects will receive either 3 months of L-arginine supplementation or a placebo. The investigators will monitor subjects' symptoms, the number of asthma exacerbations, and lung function. In addition, we will draw blood, obtain induced sputum samples and measure exhaled breath nitric oxide levels at each monthly visit.
The purpose of this study is to measure the density of a temperature-sensitive protein, named TRPV1, in the airway mucosa tissue of both non-asthmatic and moderate to severe persistent asthmatic patients. This study may generate information for developing new therapeutic strategy.
The purpose of the study is to determine whether IPL512,602 is safe and effective for the treatment of asthma symptoms in patients who remain symptomatic on a background therapy of inhaled corticosteroids.
Primary Objective: To investigate the effects of Dupilumab (SAR231893/REGN668) administered subcutaneously (SC) once weekly (qw) for 12 weeks as compared to placebo on reducing the incidence of asthma exacerbation in participants with persistent moderate to severe eosinophilic asthma. Secondary Objectives: * To assess the safety and tolerability of Dupilumab administered SC qw for 12 weeks in participants with persistent moderate to severe eosinophilic asthma. * To assess Dupilumab serum concentrations following qw SC dosing for 12 weeks in participants with persistent moderate to severe eosinophilic asthma.
