Summary

This trial aims to see if using albuterol/budesonide together is better than just using albuterol in treating mild asthma in adults. The study will last for up to

Who is the study for?
This trial is for adults with mild asthma who need to manage inflammation and symptoms. Participants should be able to commit to a study duration of up to 15 weeks, including clinic visits and video calls.
What is being tested?
The study is testing the effectiveness of two treatments: albuterol alone versus a combination of albuterol/budesonide. It focuses on how these treatments affect airway inflammation, control asthma symptoms, and reduce the need for rescue therapy over 12 weeks.
What are the potential side effects?
Possible side effects may include throat irritation, coughing, headaches, or an upset stomach from albuterol; budesonide might cause oral thrush or hoarseness. Each person's reaction can vary.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Group 1 - Participants randomized to receive albuterol/budesonideExperimental Treatment1 Intervention
Participants will be randomized based on Visit 1 FeNO levels (\< 50 ppb / ≥ 50 ppb) and geographic region. Participants who are randomized to receive albuterol/budesonide for as-needed rescue therapy will be compared to participants randomized to receive albuterol for as-needed rescue therapy.
Group II: Group 2 - Participants randomized to receive albuterolActive Control1 Intervention
Participants will be randomized based on Visit 1 FeNO levels (\< 50 ppb / ≥ 50 ppb) and geographic region. Participants who are randomized to receive albuterol/budesonide for as-needed rescue therapy will be compared to participants randomized to receive albuterol for as-needed rescue therapy.
