New treatment option for Post Deployment Related Asthma
Official title Study to Improve Deployment Related Asthma by Using L-Citrulline Supplementation
ClinicalTrials.gov ID: NCT05259904
What this study is testing
What is L-citrulline?
L-citrulline is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for post deployment related asthma.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Service men and women returning from deployment are significantly more likely to develop asthma and severe respiratory symptoms from airway obstruction. Why this happens is not well known, but exposure to diesel, burn pits, biomass smoke, and sandstorms are thought to play a role.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
