SMART@Home Feasibility Trial

The proposed research addresses the limitations or lack of a digital platform to provide remote care of medically complex patients. Previous attempts have had poor clinical validity and suffered lack of patient engagement. The study team will deconstruct the previously implemented SMART platforms to create a roadmap, platform, and template to guide clinicians to create new tools. Results from Phase 1 of this project highlighted the need for connectivity between the SMART@Home app and Bluetooth-enable devices to provide objective disease activity data as well as integration with Epic electronic health record so that providers can use the data to inform treatment planning and decision making. A subsequent pilot user validation trial is also needed to confirm development goals were met. Conducting a pilot user validation trial of the SMART@Home asthma tracker, spirometer, and action plan is the purpose of the next phases of this study. A beta test the SMART@Home Asthma Tracker and asthma action plan algorithm will take place with approximately 8 participants. Beta testing will have participants record simulated increases in symptoms to ensure appropriate levels of care is communicated via the app. Then, a group of 40 adolescent (ages 12-17) patients with asthma for a 6-month pilot Randomized Control Trial (RCT). Participants will be randomized into either the IMAAP SMART@Home (n=20) or control (n=20) groups following the completion of baseline measures to test the interactive asthma action plan functionality and impact.

Personalized Environment and Genes Study

Despite the overwhelming focus on genetic and genomic causes of human disease over the past two decades, it has been estimated that genetics is currently known to explain only 20% and 40% of the etiology of common disease. Thus, it is becoming increasingly apparent that human disease is a consequence of both genetic susceptibility and environmental exposures. Importantly, while individuals cannot change their genetic composition, we do have the ability both personally and as a society, to influence our environment, promoting health and decreasing the risk of disease. The Personalized Environment and Genes Study (PEGS) aims to determine how the environment and gene-environment interactions can inform our understanding of human health and disease. As science has evolved, so too has the science of this project. This evolution was reflected in a change in the title of this project from the Environmental Polymorphisms Registry (EPR) to the Personalized Environment and Genes Study (PEGS) to more accurately reflect the science that can be conducted. PEGS is a unique resource because of the depth of environmental phenotyping which includes extensive information from exposome surveys, as well as whole genome sequencing on a significant number of participants in the cohort. While it is small relative to genomic cohorts, none of these have the extensive environmental data that is present in PEGS. In addition, other cohorts with deep environmental data lack the depth of genomic data that is present in PEGS. Importantly, PEGS has already provided important analytic advances that are of great interest to and can be confirmed in larger cohorts such as All of Us. The Personalized Environment and Genes Study (PEGS) aims to provide a resource for environmental health translational research by examining gene-environment interactions in health and disease. PEGS is an extension of two previous efforts where it began as a pilot study, the Environmental Polymorphisms Study (EPS; IRB# 02E9004) and was approved subsequently as a full protocol titled the Environmental Polymorphisms Registry (EPR) (IRB #04-E-N0053 and transitioned to its current ID# 04-E-0053). The EPR was envisioned as a phenotype-by-genotype registry of participants who had donated DNA samples, and who had agreed to be contacted for follow-up clinical translational studies based on their DNA genotypes. At the time, the only information available was a participant s age, sex, race, and ethnicity. Further phenotyping of a participant and/or any biospecimens obtained were investigated during a follow-up translational clinical study on participants recruited based on their genotype (hence phenotype-by-genotype) and the PEGS was the first recruit-by- genotype study at the NIH. Following a period focused on recruiting approximately 15,000 participants to enable genotyping of rare (approximately 1% minor allele frequency) single nucleotide polymorphisms (SNPs), the PEGS Consortium Project was undertaken in 2010- 2011 to examine, using the DNA of nearly 4,000 participants, approximately 700 SNPs in approximately 80 environmental response genes that work in concert with environmental exposures to elicit a phenotype. Several clinical follow-up studies, genotype-phenotype association studies, and publications have resulted from the PEGS Consortium Project. To expand phenotype information available to researchers, the Health and Exposure Questionnaire was administered between 2013-2014. In 2017, a more detailed Exposome Questionnaire which includes questions relating to the external and internal exposome was administered. This was an important resource through which to integrate exposures with genotype-phenotype association studies. Whole genome sequencing has now been performed on approximately 4700 participants who were reconsented for this purpose, as indicated above. Questionnaire data was fully adjudicated and combined in a robust and searchable database. With the increased power of the data available, the project was renamed as the Personalized Environment and Genes Study (PEGS) and rolled out in Sept. 2021.

A Study to Learn How Different Amounts of the Study Medicine Called PF-08103402 Are Tolerated and Act in the Body in Healthy Adults or Adults With Mild To-moderate Asthma

The purpose of this study is to learn about the safety of a new study medicine called PF-08103402 in healthy adults (do not have disease) and or in adults with mild-to-moderate asthma. This is the first time the study medicine is being given to people. For Parts A, B, C, D and F, the study is seeking participants who: * Are healthy (do not have disease) males or females who can no longer have children, * Are 18 to 65 years old, * Have a body mass index (BMI) of 16 to 32 kilograms per meter squared and a body weight of more than 50 kilograms (110 pounds). Body mass index is a way to measure body fat by using a person's height and weight For Part A (optional group or cohort 3: Japanese participants only): * A body weight of more than 45 kilograms (100 pounds). * Have 4 biological Japanese grandparents who were born in Japan. For Part E only: * Adults with a documented history of asthma (confirmed by a doctor) for at least 12 months before entering the study. * Have a body mass index (BMI) of 16 to 35 kilograms per meter squared and a total body weight of more than 50 kilograms (110 pounds). The study has six parts: Part A, Part B, Part C, Part D, Part E and Part F. The study medicine will be taken as a suspension or tablet by mouth 1 time a day (except in Parts B and E where it will be taken 1 time a day for 14 days) at the study clinic. The study will help understand: * how the body processes the study medicine in healthy participants (Parts A and B), * how much of the study medicine gets into the bloodstream and if food affects the amount of study medicine in the blood in healthy participants (Part C), * how the study medicine is broken down and leaves the body in healthy participants (Optional Part D), * how the study medicine is processed in adults with mild-to-moderate asthma (Optional Part E), * if taking the study medicine together with another medicine affects how each medicine is processed by the body in healthy participants (Optional Part F). Participants will take part in the study for about 10 weeks (Parts A and F), 12 weeks (Part B), 9 weeks (Parts C and D), and 16 weeks (Part E). During this time, they will have 2 study visits at the study clinic and up to 28 overnight stays (Part A), 18 overnight stays (Parts B and E), 10 overnight stays (Part C), 11 overnight stays (Part D), and 16 overnight stays (Part F). The study team will also call participants 1 time over the phone at the end of the study to assess how they are doing. Study measurements will be taken by body examination, monitoring side effects, blood and urine tests, heart tests (ECG), vital signs (blood pressure and pulse), questionnaires (Parts C and E), stool samples (Part D only), and breathing tests (Part E only).

Dose-Ranging Study of LQ036 Single-Domain Antibody Nebulization Solution in Poorly Controlled Asthma

What is the goal of this study? The goal of this clinical trial is to find out whether the study drug LQ036 (a nebulized solution taken by inhaling through a nebulizer) works to improve lung function and asthma control in people whose asthma is not well controlled. The study will also learn about the safety of LQ036, how the body processes it, and whether the body develops an immune response to it. What are the main questions? The most important question is: • Does LQ036 improve lung function (measured by FEV₁ - the amount of air you can blow out in one second) more than a placebo at Week 12? Other important questions include: * Does LQ036 improve lung function at other time points (weeks 1, 2, 4, 8, 16, 20, 24)? * Does LQ036 reduce asthma attacks (sudden worsening of asthma that needs extra treatment)? * Does LQ036 help people use less rescue medication (inhaler for quick relief) and have more days without asthma symptoms? * Does LQ036 improve scores on asthma control and quality of life questionnaires? * What medical problems do participants have when taking LQ036?

Remote Anxiety Management for ICS-resistant Asthma Study

This study, the Remote Anxiety Management for ICS-resistant Asthma Study (RAMICS), explores strategies to improve medication adherence and anxiety management in asthma patients who are resistant to using inhaled corticosteroids (ICS) due to anxiety. Asthma is a chronic respiratory disease affecting millions worldwide, and ICS therapy is essential for controlling symptoms and preventing severe exacerbations. However, many patients struggle with adherence, especially those with anxiety about ICS side effects. RAMICS is a multicenter, open-label, randomized controlled trial designed to evaluate the effectiveness of personalized telephone-based interventions, including medication education, progressive muscle relaxation (PMR), motivational interviewing (MI), and lung rehabilitation guidance. The study will enroll 216 adult asthma patients with poor ICS adherence and clinically significant anxiety. Participants will be randomized into two groups: the intervention group, receiving weekly telephone sessions, and the control group, receiving standard follow-up calls. The study aims to assess improvements in ICS adherence, reductions in anxiety and depression, better asthma symptom control, and enhanced quality of life. Outcomes will be evaluated immediately after the 8-week intervention and during a 3-month follow-up. By addressing both psychological and medication adherence challenges, this research aims to provide practical solutions for improving asthma management.

NHALES (Natural History of Asthma With Longitudinal Environmental Sampling)

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.

Execise Intervention in Adult Severe Asthma

Physical activity has been shown to improve asthma control in individuals with asthma. Patients with severe asthma frequently experience exacerbations, which often result in a physically inactive lifestyle. The investigators therefore hypothesize that patients with severe asthma who initiate biological therapy may particularly benefit from increased physical activity, both in terms of exercise capacity and asthma control. The aim of this study is to determine whether an individually tailored exercise program improves exercise capacity and asthma control in patients with severe asthma. Additionally, the study evaluates the effects of the intervention on asthma symptoms, frequency of exacerbations, lung function, quality of life, and body composition. The primary outcome is the change in exercise tolerance, measured as peak oxygen uptake during cardiopulmonary exercise testing. Secondary outcomes include asthma symptoms (proportion of patients reporting improvement based on the Asthma Control Test), frequency of exacerbations, changes in lung function (FVC and FEV1), asthma-related quality of life (AQLQ), and changes in body composition (body mass index and waist circumference). At baseline, all participants undergo fitness assessments, including cardiopulmonary exercise testing and muscle strength tests. Participants are then randomized into two groups. The intervention group receives an individually tailored 6-month exercise program designed by a sports medicine physician and a physiotherapist based on baseline fitness level. The control group receives standard advice to increase physical activity. Asthma medication is managed according to standard clinical practice in both groups. Fitness assessments are repeated at 6 months for all participants, and asthma control is evaluated at 6 and 12 months
