This is an interventional, randomized, parallel group, treatment, Phase 3b/4, double blind, 2-arm study to assess the effect of dupilumab compared to standard of care therapy on preventing or slowing the rate of lung function decline in adult patients with uncontrolled moderate to severe asthma. The estimated duration is 4±1 weeks of screening and run-in period, followed by a 3-year double blinded treatment period. There will be a post-treatment follow-up (FU) period up to 12 weeks.

Patients with obese late onset (after childhood) asthma can have lower FeNO levels, yet be highly symptomatic and poorly responsive to inhaled steroids. This is a common asthma phenotype, particularly among females. This reduction of NO occurs through increased arginase activity and uncoupling of NO synthase (NOS), by accumulation of asymmetric di-methyl arginine (ADMA), which further lowers the L-arginine/ADMA ratio, preferentially promoting reactive oxygen species (ROS) formation and inflammation at the expense of NO. Indeed, in patients with obese late onset asthma, lower L-arginine/ADMA plasma ratios are associated with reduced FeNO, increased bronchial hyperreactivity, and greater asthma morbidity. In our pilot studies, the administration of L-citrulline, as an L-arginine donor, to patients with obese late onset asthma increased the L-arginine/ADMA ratio, FeNO levels, and improved asthma control and lung function. Therefore, the objectives of the protocol are to: a) determine the efficacy of L-citrulline, as an add-on treatment to improve the asthma control and lung function in obese late onset asthmatics; b) leverage the use of asthmatic and control cells to further understand obesity-related changes in epithelial airway NO metabolism, and how these changes relate to bronchoconstriction and lung function, c) determine airway epithelial changes in mitochondrial function and bioenergetics in obese late onset asthmatics and how these are modified by L-citrulline. To do this, 54 obese late onset asthmatics with suboptimal control will be blindly randomized, in a cross over study, comparing 15g/day of L-citrulline vs. placebo, in two 8-week treatment periods with a 6-week washout in between. The co-primary study outcomes are asthma control (ACQ, ACT) and FeNO, and secondary endpoints plasma L-arginine/ADMA, FEV1 and PC20 methacholine. Parallel to this study, a small study of 10 healthy obese controls will receive open label L-citrulline for 7 weeks to establish comparative reference values for the study aims. During the initial treatment phase, 50% of study participants will be randomly allocated to undergo pre and post L-citrulline treatment bronchoscopy to obtain BAL and airway epithelial cells. The research group proposing this study is highly experience in asthma clinical trials, implementation of cross over design studies, and in the use of research bronchoscopies. Read Less

This is a dose-range finding, double-blind, placebo-controlled, phase IIb study designed to assess efficacy and safety of tozorakimab administered subcutaneously in adult participants with uncontrolled asthma receiving medium-to-high dose inhaled corticosteroids. Read Less

The purpose of this study is to compare the effect of budesonide/albuterol metered-dose inhaler (BDA MDI) with albuterol sulfate metered-dose inhaler (AS MDI), both administered as needed, on the annualized rate of severe asthma exacerbations in adolescents with a documented clinical diagnosis of asthma and at least one severe exacerbation in the prior year.

This is a randomised, placebo-controlled, double-blind study to assess the efficacy and safety of Atuliflapon administered once daily over a 12-week treatment period to adult participants with moderate to severe uncontrolled asthma. Read Less

Background: - Asthma is a serious clinical and public health problem. Researchers want to collect data to better understand how bacteria and other things in the environment can affect people's asthma. Eligibility: - Nonsmoking adults age 18 - 60 who have moderate to severe asthma. Design: * Participants will complete a medical history form before the first visit. * Study visits will include collecting medical history, and conducting physical exam, lung and smoking tests. Participants will give blood, urine, stool, dust, saliva, and sputum samples. * Participants will take tests that measure their breathing abilities. They will give saliva samples for DNA study. They will get kits to collect stool and dust samples at home. They will fill out surveys. * Participants will have visits every 6 months for 5 years. They can schedule sick visits, if needed, at no cost to the participant. For all visits, they will have asthma check-ups and get treatment, at no cost to the participant. * Some participants may take part in a sub-study that includes one 4-hour visit. They will have medical history, physical exam, and lung tests. They will have urine tests to check for pregnancy and tobacco exposure. Then they will have bronchoscopy. For this, an intravenous line will be placed in an arm vein. The nose and throat will be numbed. A flexible fiber-optic tube will be inserted into their airways through the nose. Their airways will be examined and areas of their lung will be washed. A small sample of cells will be taken. Read Less

This is a parallel-group, Phase 2, randomized, double-blind, placebo-controlled, 2-arm study for the treatment of asthma. The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with SC lunsekimig compared with placebo in male and female participants (aged 18 to 80 years, inclusive) with asthma, who are not currently eligible for biologic treatments. Study details include: * The study duration will be approximately 64 weeks for participants not transitioning into the LTS study and approximately 60 weeks for participants transitioning into the LTS study. * The investigational treatment duration will be up to approximately 52 weeks. * The number of visits will be 18.

This is a phase 2, open-label extension study to evaluate the long-term safety and efficacy of lunsekimig in adult participants with moderate-to-severe asthma who have previously completed the parent study. After completion of the parent study, eligible participants will be offered the opportunity to participate in the long-term extension (LTE) study with lunsekimig. The study duration will be up to 100 weeks with a treatment duration being up to 96 weeks. Read Less

The goal of this study is to evaluate the implementation of the Coach McLungsSM shared decision making (SDM) intervention into primary care across a large healthcare system. Coach McLungsSM is a virtual evidence-based asthma intervention with built-in asthma education and clinical decision support. All asthma patients aged 5-17 who attend these practices will be assessed for uncontrolled asthma. Asthma exacerbations attributed to emergency department visits, hospitalizations, and oral steroid use, will be evaluated to serve as surrogate measures for patient-centered asthma outcomes.

Background: - Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation. Researchers are interested in studying how the body responds to certain environmental factors, and whether the body s response can contribute to chronic illnesses or diseases such as asthma and certain types of cancers. Objectives: - To examine how specific genes and proteins in blood cells respond to environmental exposures. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: * The study will involve one visit of 45 to 60 minutes. * Participants will be screened with a brief physical examination and finger stick to determine if they are eligible to donate blood for the study, and will complete a questionnaire about any medications or other drugs (e.g., cigarettes) they may be taking. * Participants will provide a blood sample for research purposes.
