Official title

Phase II Study of L-arginine in Severe Asthma Patients Grouped by Exhaled Nitric Oxide Level

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The major impact of this study will be to identify the adult severe asthma cohort that will benefit from supplemental L-arginine therapy. The investigators hypothesize that a subset of adult severe asthma patients will respond to supplemental L-arginine and derive clinical benefit from the addition of this therapy to standard-of-care asthma medications. The investigators hypothesize that the patients that benefit most will have low exhaled nitric oxide concentrations (\< 20 ppb) at baseline.
