The overall aim of the study is to determine the clinical efficacy and mechanisms of action of anti-IL-4a (dupilumab) as treatment for patients with Aspirin-Exacerbated Respiratory Disease (AERD).
Nasal Polyps, Asthma, Aspirin-Induced, Aspirin-Exacerbated Respiratory Disease, Aspirin-Sensitive Asthma With Nasal Polyps
Aspirin Exacerbated Respiratory Disease (AERD) is a relatively homogeneous disease characterized by adult-onset severe asthma, development of non-cancerous growths in the nasal canal (i.e. nasal polyps) and aspirin allergy. The cause of AERD is unknown, although likely results from environmental insults in combination with genetic susceptibility. AERD disease homogeneity increases the possibility of discovering narrowly-defined genetic contributors, and makes it an ideal population to study the genetic and epigenetic changes that cause asthma. Researchers recently discovered that gene expression of epithelial growth and repair (EGR) genes are substantially decreased in bronchial airway epithelial cells of severe asthmatics compared to less severe asthmatics and healthy controls. This new finding indicates that epithelial integrity and related processes may be of primary importance to the development of severe asthma, and potentially the severe asthma subtype, AERD. This finding was later supported in a subsequent lab model, which showed that blocking a central epithelial repair and differentiation gene, human epidermal growth factor receptor 2 (ERBB2), decreased healing time of bronchial epithelial cells after injury. Thus, the objective of the proposed study is to determine whether EGR gene are also down-regulated in AERD, a homogeneous severe asthma subtype. As an extension, the researchers will also determine whether genetic mutations and/or epigenetic changes relate to and potentially explain this down-regulation of EGR genes. Specifically, the researchers plan to obtain gene expression of freshly brushed nasal airway epithelial cells of 140 AERD patients, 70 non-aspirin sensitive asthma patients, and 35 healthy controls, noting that nasal epithelial gene expression has recently been shown to mirror lung epithelial changes in asthmatic airways. Swabbing the nasal canal for epithelial cells allows to evaluate airway epithelial cell gene expression non-invasively. Our experimental design contrasts AERD gene expression profiles against healthy controls, and determines whether EGR genes are depressed in AERD relative to health controls. As a corollary, the researchers look to discover an AERD-specific gene expression profile which may one-day aid in diagnosis and expand current knowledge of disease mechanisms. As an extension, the researchers will correlate gene expression changes, specifically any finding of down-regulated EGR genes, with methylation changes (i.e. epigenetic changes) and genetic mutations.
Aspirin Exacerbated Respiratory Disease, Aspirin-Sensitive Asthma, Nasal Polyps
The overall aim of the study is to determine the efficacy of oral ifetroban, a novel antagonist of T prostanoid (TP) receptors, as a treatment for patients with aspirin-exacerbated respiratory disease (AERD).
Nasal Polyps, Asthma, Aspirin-Induced, Aspirin-exacerbated Respiratory Disease, Aspirin-Sensitive Asthma With Nasal Polyps
The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.

Gamma tocopherol (gt) is a naturally occurring form of vitamin E that is found in many foods, and is also commercially available as a vitamin supplement. The purpose of this Phase 1 research study is to see if two doses of gt, 600mg and 1200mg, are safe (do not cause gastrointestinal distress or other problems), and can cause changes in your blood levels of gt and other antioxidants. This study will also examine if there is a difference in response between asthmatic and non-asthmatic adults when taking the same dose of gt. Phase 1 research studies like this one are not intended to be a treatment, but are a scientific investigation.

This study was a 2-treatment period, randomized, multicenter parallel-group study. The overall purpose of this study was to provide long- term safety data for fevipiprant (QAW039) (Dose 1 and Dose 2), compared with placebo, when added to the Global Initiative for Asthma (GINA) steps 3, 4, and 5 standard-of-care (SoC) asthma therapy (GINA 2016), in patients with moderate-to- severe asthma. The purpose of this study was to provide long-term safety data for QAW039 150 mg once daily and 450 mg once daily, compared with placebo, when added to GINA steps 3, 4, and 5 standard-of-care asthma therapy (GINA 2020) in adult and adolescent (≥12 years) patients with moderate-to-severe asthma. The study included 2 cohorts of patients: 1. Rollover patients who had completed any of the four Phase 3 pivotal efficacy studies with QAW039 (QAW039A2307, QAW039A2314, QAW039A2316, or QAW039A2317, hereafter referred to as Studies A2307, A2314, A2316, and A2317), thus providing data for a longer duration of exposure, and 2. New patients who had not previously participated in a study of QAW039, permitting an increase in the number of patients with long-term exposure to QAW039. By including these 2 categories of patients, the total number of patients treated with QAW039 as well as the duration of exposure to QAW039 treatment was substantially increased, supporting evaluation of the safety profile of QAW039.

Endotoxin is a component of outdoor air pollution, an air contaminant found in a number of different workplaces, and is even found in homes. The endotoxin used for this study is obtained from the National Institutes of Health, and is called "Clinical Center Reference Endotoxin", or CCRE. The purpose of this Phase 1 research study is to identify a dose of inhaled endotoxin that is safe (does not cause prolonged cough, shortness of breath or other problems), but causes changes in your sputum cell samples that the scientists can measure. Phase 1 research studies like this one are not intended to be a treatment, but are a scientific investigation. Eventually, with these types of studies we will be able to examine why some people are more sensitive to endotoxin. Scientists at other universities have found that while most people do not have a considerable lung response to endotoxin at doses as high as 60,000 EU (endotoxin units), a few respond to as little as a total dose of 4500 EU. Our study is designed to identify if using a dose of 20,000 EU causes changes in the lung cells but does not cause symptoms in our study subjects. In our previous studies in our lab, using an endotoxin from another source, we have used higher doses (15,000 EUs) in subjects with asthma with no major problems, and we have used 10,000 EUs of CCRE in subjects with allergies and asthma without problems. We have used 20,000 EUs of CCRE in healthy individuals with no major problems.

Inhaled corticosteroids are widely used as the primary therapy for asthma, which affects approximately 20 million people in the United States. While many patients respond to corticosteroid therapy, as many as 25-30% of patients with severe asthma have asthma that is difficult to treat or steroid insensitive. Predictive biomarkers for the rapid identification of patients with asthma who will achieve adequate control of their symptoms with inhaled corticosteroids has the potential to significantly improve asthma management. This proposal is based on the hypothesis that alterations in gene expression in epithelial cells of the buccal mucosa can be used as a reliable biomarker to predict corticosteroid response in patients with asthma. The goals of this proposal will determine if gene expression in epithelial cells of the buccal mucosa from patients with asthma is in concordance with gene expression profiles that have been identified through more invasive sampling techniques of the airway epithelium of asthma patients. The Specific Aims of this proposal are to 1) investigate the level of variability in gene expression of a subset of inflammatory markers in buccal epithelium from adult patients with asthma. Aim 1 will be carried out by collecting buccal samples from three cohorts of subjects (18-55 years of age) from the Pulmonology and Allergy Clinics at Truman Medical Center during regularly scheduled outpatient visits as follows: 1) healthy control adult subjects (n=10), 2) patients with asthma treated only with a short-acting beta2-agonist (SABA, n=10), and 3) patients with asthma treated with low-dose ICS (n=10). Relative gene expression of inflammatory markers will be determined using quantitative RT (reverse transcription)-PCR and variability in gene expression will be determined within and between the three cohorts. Data from the pilot studies described in this proposal will aid in the determination of appropriate study population sizes for future investigations with the long-term objective to use changes in gene expression (in buccal epithelial cells) as a dynamic biomarker for determining corticosteroid response in patients with asthma.

Background: Allergic or sinus diseases can affect the skin, sinuses, airways, and other parts of the body. Examples include pollen and environmental allergies, food allergies, asthma, and eczema. To learn more about how to prevent and treat these diseases, researchers need to study data, blood, fluid, and tissue samples from people affected by them. Objective: To collect data, blood, fluid, and tissue samples from people with allergic or sinus diseases. Eligibility: People aged 3 to 100 years with allergic or sinus diseases. Design: Participants will have at least one clinic visit, and most participants will have a baseline visit, annual visit, and an end of study visit. The duration of the study is 1 to 3 years. During the first clinic visit, the following procedures will be done to collect data, blood, fluid, and tissue samples: * Blood will be collected. * Cells and fluid may be collected from the inside of the nose using a long swab, and a small piece of skin may be scraped from inside the nose. * Skin cells will be collected by rubbing with a cotton swab. * A urine sample will be collected. * Allergy skin prick tests. Allergy-causing substances will be placed on the back or arm and the skin underneath gently scratched. If the participant is allergic to the substance, the skin may become red, itchy, and swollen locally ( at the site of the test). * Lung function test. Participants will breathe into a machine that measures the air moving in and out of their lungs. * If, as part of their routine care, participants are undergoing procedures such as having nasal polyps removed, skin tissue samples taken, or gastrointestinal biopsies, additional tissues may be collected for this study. * Participants will complete online questionnaires regarding their symptoms, health, and life. Participants may return for more visits for up to 3 years. ...

In this clinical study we aim to determine the effect of allergy immunotherapy in decreasing asthma and allergy related disease in children who had multiple episodes of wheezing and who are at high risk for developing persisting asthma. These risks include a history of asthma in the parents, allergies to environmental allergens (such as dust mite, cockroach or mouse) and other allergic diseases such as eczema or food allergies. Allergy Immunotherapy is not new and has been practiced for many years to treat asthma and environmental allergies in older children and adults, but has not yet been systematically studied in young children.

Gluococorticoids are commonly prescribed to treat a number of diseases including the majority of inflammatory diseases. Despite considerable inter-personal variability in responses to glucocorticoids between asthmatics, an insensitivity rate of about 30% and the risk of adverse side effects of glucocorticoid therapy, no assay is currently performed to determine sensitivity in severe and non-severe asthmatics prior to treatment. The purpose of this study is to perform a whole blood ex vivo stimulation assay to interrogate known glucocorticoid receptor (GR) up- and down-regulated genes to indicate glucocorticoid sensitivity and compare the results between severe and non-severe asthmatics.

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) for the potential treatment of moderate-to-severe asthma. Asthma is a condition that makes it challenging to breathe, which negatively impacts the quality of life and functioning of people who are affected. This study is seeking participants who: * Are 18 to 70 years old * Have had moderate-to-severe asthma for at least 12 months that is not well controlled * Have been taking their regular maintenance treatment(s) for asthma over the last 12 months All participants will receive PF-07275315 or a placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. PF-07275315 or placebo will be given as multiple shots in the clinic over the course of 12 weeks. We will compare the experiences of people receiving PF-07275315 to those of the people who do not. This will help us determine if PF-07275315 is safe and effective. Participants will be involved in this study for about 9.5 months. During this time, they will have 10 visits at the study clinic.
