Asthma Exacerbation

The study is a randomized controlled trial on the effect of emergency department initiation of Airsupra on acute asthma "recurrence" at 3 months and other related outcomes (acute asthma relapse, asthma control).

This study evaluates the diagnostic performance, usability, and clinical utility of the Medentum Diagnostik platform, a multisensor device with integrated software and artificial intelligence, in pediatric patients with asthma and ENT conditions. Participants will be assigned to either home-based use of the Diagnostik platform with telehealth-supported clinician evaluation or standard in-person care. The primary objective is to assess agreement between AI-generated diagnoses and clinician diagnoses obtained during study encounters, including telehealth evaluations in the Diagnostik arm and in-person evaluations in the standard-of-care arm. Secondary objectives include evaluating agreement between AI-generated diagnoses and independent research team diagnoses, as well as assessing usability, patient and caregiver satisfaction, healthcare utilization, and clinical outcomes such as asthma control and symptom resolution. This study will also evaluate differences in healthcare utilization, including in-person visits, emergency care use, and time to diagnosis and treatment, between study groups.

Nested Phase 1-2 Trial of RIG-101 in Healthy and Asthmatic Participants Assessing Safety, Tolerability and Viral Challenge Efficacy

The goal of this clinical trial is to learn if adding Air Quality Index (AQI) information to asthma action plans works to improve asthma outcomes in children. It will also learn about children with asthma who report being more sensitive to outdoor air pollution. The main questions it aims to answer are: * Does adding either information about the EPA-AQI or commercial AQI improve asthma outcomes over time? * Are there changes in nasal gene expression in children with asthma who report they are more sensitive to outdoor air pollution? Researchers will compare EPA-AQI and the commercial-AQI groups to a control group to either AQI works to improve asthma. Participants will: * Receive standardized outdoor air pollution education and an asthma action plan * Provide nose and blood specimens * Have visits every 4 weeks for 48 weeks, 10 will be conducted by telephone calls and 3 visits will be in person.
