Phase 2 Study: GCRC: Effects of L-arginine Supplementation on Exhaled Nitric Oxide and Clinical Exacerbations in Adults With Moderate to Severe Asthma

University of California, Davis·interventional·Posted Jan 23, 2006·Updated May 30, 2017

In Brief

A Phase 2 clinical trial evaluating L-arginine and Placebo for Asthma. Completed, enrolled 20 participants across 1 site.

Detailed Summary

Nitric oxide is an important marker of airway inflammation in asthma. Nitric oxide may have a protective role in patients with moderate to severe asthma. The investigators believe that a natural amino acid, L-arginine, that augments nitric oxide levels can decrease asthma exacerbations and improve the asthma care of moderate to severe asthma patients. This study is a randomized, placebo controlled trial in which subjects will receive either 3 months of L-arginine supplementation or a placebo. The investigators will monitor subjects' symptoms, the number of asthma exacerbations, and lung function. In addition, we will draw blood, obtain induced sputum samples and measure exhaled breath nitric oxide levels at each monthly visit.
