L-citrulline supplement for deployment-related asthma symptoms
Treatments studied
Part of Immune system & allergy, Lungs & breathing clinical trials.
This trial studies whether an L-citrulline supplement can improve asthma control in people who developed persistent asthma symptoms after military deployment. If you qualify, you may be asked to track symptoms and breathing test results to see if the supplement helps.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 70 years old and can sign consent forms
- You have deployment-related asthma (symptoms started or worsened after post-9/11 Southwest Asia deployment) and past breathing-test results support asthma
- Your baseline asthma control is not well controlled (for example, ACQ is 0.5 or higher, or ACT is under 19)
- You can do breathing tests (spirometry) in a repeatable way, as the study asks
- You have not had a respiratory infection, or a breathing-related ER visit, within the last 4 weeks
- You can’t be pregnant, and you don’t have known allergy/intolerance to L-arginine or L-citrulline

This Phase 2 study tests anti-inflammatory lipid mediators in people with asthma. You may be eligible if your asthma is not well controlled despite regular inhaler use and you meet the specific lung function and health criteria.
This Phase 2 trial tests whether adding L-citrulline can improve asthma control in overweight adults whose asthma started later in life. It compares your asthma symptoms and lung testing results to see if the supplement helps when asthma is already being treated.
This study tests an investigational drug (called JNJ-95597528) taken as a pill, to see if it can reduce asthma attacks and improve control in people with moderate to severe asthma that isn't well controlled by current inhalers. It may be a new option to help reduce airway inflammation and improve your breathing.
This trial tests a new inhaled medication called LQ036 to see if it can help people whose asthma is not well controlled with their current inhalers. Participants must have had at least one severe asthma flare-up in the last year and show signs of airway inflammation.
This study tests a slow-release form of the hormone DHEA as an add-on treatment for asthma. It aims to see if it can improve asthma control and reduce inflammation, possibly helping you breathe better.
This study tests a program that combines exercise and other support to help people with difficult-to-control asthma feel better and be more active. It aims to improve your symptoms and quality of life.
